Subject: [PATCH 001/244] feat(pets): pet engine + display.pet config

Add the shared pet engine under agent/pet/: spritesheet manifest loading
and in-process caching, six-state animation model, frame rendering, and
the persistent pet store. Register the display.pet config block (pet,
scale, enabled, etc.) that every surface reads from. Covered by
tests/agent/test_pet_engine.py.

+"""Petdex pet engine — shared core for the CLI, TUI, and desktop surfaces.
+
+Petdex (https://github.com/crafter-station/petdex) is a public gallery of
+animated sprite "pets" for coding agents.  Each pet is a ``pet.json`` plus a
+``spritesheet.{webp,png}`` of 192×208 px cells. Current Codex/petdex sheets use
+an 8-column × 9-row atlas; older Hermes/petdex sheets used an 8-row atlas.
+Hermes infers the row taxonomy from the sheet and maps agent activity onto
+idle/run/review/failed/wave/jump.
+
+This package is the **single source of truth** for the feature so the base
+CLI (Python) and TUI (Ink, via ``tui_gateway``) never duplicate the hard
+parts:
+
+- :mod:`agent.pet.constants` — frame geometry + the :class:`PetState` enum.
+- :mod:`agent.pet.state`     — map agent activity → a :class:`PetState`.
+- :mod:`agent.pet.manifest`  — fetch the public petdex manifest.
+- :mod:`agent.pet.store`     — install / list / resolve pets on disk
+                               (profile-aware via ``get_hermes_home()``).
+- :mod:`agent.pet.render`    — decode a spritesheet and encode frames for a
+                               terminal (kitty / iTerm2 / sixel graphics
+                               protocols, with a Unicode half-block
+                               fallback).
+
+Rendering in the Electron desktop is necessarily TypeScript (canvas), but it
+reuses the same on-disk store and the same state semantics.
+
+The whole feature is a *display* concern: it adds no model tool, mutates no
+system prompt or toolset, and therefore has zero effect on prompt caching.

Subject: [PATCH 002/244] feat(pets): CLI pet pane + /pet command

Render the reactive pet pane in the classic CLI (steady redraw,
right-aligned) and wire the /pet command to list and switch pets, plus an
enable/disable toggle. Backed by hermes_cli/pets.py and the CLI commands
mixin, registered in the central command registry. Covered by the CLI pet
pane and toggle tests.

Subject: [PATCH 003/244] feat(pets): TUI pet pane, picker + gateway RPCs

Add the Ink pet sprite pane, the interactive /pet picker overlay, and live
pet switching/rescale driven by new tui_gateway RPCs (pet state, pet.scale,
per-state frames). Wires pet flash state and the picker into the TUI layout
and slash handler. Covered by the slash-handler test.

Subject: [PATCH 004/244] feat(desktop): floating pet, pop-out overlay + Cmd+K
 picker

Add the in-window floating pet (sprite, speech bubble, contact shadow,
profile-scoped, resize-safe) and a pop-out always-on-top overlay window
with gestures and notifications. Add the Cmd+K pet picker page plus the
appearance gallery and size slider in settings. Includes the pet stores,
electron overlay wiring, i18n strings, and store tests.

+name: petdex
+description: Install and select animated petdex mascots for Hermes.
+version: 1.0.0
+author: Hermes Agent
+license: MIT
+platforms: [linux, macos, windows]
+metadata:
+  hermes:
+    tags: [petdex, mascot, display, cli, tui, desktop]
+    category: productivity
+    homepage: https://petdex.dev
+---
+
+# Petdex Skill
+
+Browse, install, and select animated "pet" mascots from the public
+[petdex](https://github.com/crafter-station/petdex) gallery. An installed pet
+reacts to agent activity (idle, running a tool, reviewing, error, done) across
+the Hermes CLI, TUI, and desktop app. This skill drives the `hermes pets` CLI
+and the `display.pet` config — it does not generate sprites.
+
+## When to Use
+
+- The user wants a desktop/terminal mascot or asks about "pets" / petdex.
+- The user wants to change, preview, or disable the active pet.
+- Diagnosing why a pet isn't showing (terminal graphics support, config).
+
+## Prerequisites
+
+- Network access to `petdex.dev` for the gallery/manifest (read-only, no auth).
+- Pillow (a core Hermes dependency) for sprite decoding — already installed.
+- For full-fidelity terminal rendering: a graphics-capable terminal (kitty,
+  Ghostty, WezTerm, iTerm2, or sixel). Otherwise a truecolor Unicode
+  half-block fallback is used automatically.
+
+## How to Run
+
+Use the `terminal` tool to run `hermes pets <subcommand>`.
+
+## Quick Reference
+
+| Goal | Command |
+| --- | --- |
+| Browse the gallery | `hermes pets list` (add a substring to filter: `hermes pets list cat`) |
+| List installed pets | `hermes pets list --installed` |
+| Install a pet | `hermes pets install <slug>` (add `--select` to make it active) |
+| Set the active pet | `hermes pets select <slug>` (omit slug for a picker) |
+| Resize the pet everywhere | `hermes pets scale <factor>` (e.g. `0.5`, clamped 0.1–3.0) |
+| Preview/animate in terminal | `hermes pets show [slug] [--cycle] [--state run]` |
+| Disable the pet | `hermes pets off` |
+| Remove a pet | `hermes pets remove <slug>` |
+| Diagnose setup | `hermes pets doctor` |
+
+## Procedure
+
+1. Find a pet: `hermes pets list <query>` and note its `slug`.
+2. Install + activate: `hermes pets install <slug> --select`.
+3. Preview it: `hermes pets show` (Ctrl+C to stop).
+4. Confirm setup: `hermes pets doctor` — shows the resolved pet, configured
+   render mode, detected terminal graphics protocol, and effective mode.
+
+Pets install into `<HERMES_HOME>/pets/<slug>/` (profile-aware). Selecting a pet
+writes `display.pet.slug` + `display.pet.enabled` to `config.yaml`.
+
+## Configuration
+
+Under `display.pet` in `config.yaml`:
+
+- `enabled` (bool) — master on/off.
+- `slug` (str) — active pet; empty = first installed.
+- `render_mode` — `auto` (detect) | `kitty` | `iterm` | `sixel` | `unicode` | `off`.
+- `scale` (float) — on-screen size of the native 192×208 frames (default 0.33,
+  clamped 0.1–3.0). One knob resizes every surface; set it with
+  `hermes pets scale <factor>`, the `/pet scale` slash command, or the desktop
+  Appearance slider.
+- `unicode_cols` (int) — width in columns for the Unicode fallback.
+
+## Pitfalls
+
+- A pet only shows once one is installed AND selected (`enabled: true`).
+- Inside a pipe/redirect (no TTY) terminal rendering is disabled by design.
+- The petdex npm CLI installs to `~/.codex/pets`; Hermes uses its own
+  profile-scoped `<HERMES_HOME>/pets/` instead — install through `hermes pets`.
+
+## Verification
+
+- `hermes pets doctor` reports `✓ ready` when a pet is installed, selected,
+  enabled, and Pillow is importable.

+title: "Pets (Petdex Mascots)"
+description: "Adopt an animated mascot that reacts to agent activity across the CLI, TUI, and desktop app"
+---
+
+# Pets
+
+Hermes can show an animated **pet** — a small mascot sprite that reacts to what
+the agent is doing (idle, running a tool, thinking, finishing, failing) across
+the **CLI**, **TUI**, and **desktop app**. Pets come from the public
+[petdex](https://github.com/crafter-station/petdex) gallery.
+
+Pets are purely cosmetic. They have **no effect on prompt caching, tokens, or
+the agent's behavior** — the sprite is a display concern only. The feature is
+**off by default** and stays dormant until you install and select a pet.
+
+## How it works
+
+- Pets are installed into your profile's `pets/` directory
+  (`<HERMES_HOME>/pets/<slug>/`), so each [profile](../profiles.md) keeps its
+  own set.
+- Selecting a pet writes `display.pet.slug` and `display.pet.enabled` to
+  `config.yaml` — nothing is stored as a secret or env var.
+- Each surface watches the activity it already tracks and maps it to one of six
+  animation states. The mapping lives in one place so every surface behaves the
+  same:
+
+  | Agent activity | Pet state |
+  | --- | --- |
+  | A tool/turn just failed | `failed` |
+  | A plan finished (all todos done) | `jump` (celebrate) |
+  | A turn finished cleanly | `wave` |
+  | A tool is executing | `run` |
+  | The model is thinking/reading | `review` |
+  | Turn in flight (unspecified) | `run` |
+  | Blocked on you (a clarify/approval prompt is open) | `waiting` (falls back to `idle` on legacy 8-row sheets) |
+  | Nothing happening | `idle` |
+
+## Rendering
+
+In the terminal (CLI/TUI), Hermes renders the sprite at full fidelity when your
+terminal supports a graphics protocol (**kitty**, **Ghostty**, **WezTerm**,
+**iTerm2**, or **sixel**). Otherwise it falls back automatically to a truecolor
+Unicode **half-block** rendering. Inside a pipe or redirect (no TTY), terminal
+rendering is disabled by design.
+
+The desktop app draws the pet as a floating sprite on a canvas and toggles it
+from **Settings → Appearance**.
+
+## Quick start (CLI)
+
+```bash
+# Browse the gallery (filter by substring)
+hermes pets list
+hermes pets list cat
+
+# Install a pet and make it active in one step
+hermes pets install boba --select
+
+# Preview / animate it in your terminal (Ctrl+C to stop)
+hermes pets show
+
+# Check your setup
+hermes pets doctor
+```
+
+## `hermes pets` commands
+
+| Goal | Command |
+| --- | --- |
+| Browse the gallery | `hermes pets list [query] [--limit N]` |
+| List installed pets | `hermes pets list --installed` |
+| Install a pet | `hermes pets install <slug> [--select] [--force]` |
+| Set the active pet | `hermes pets select [slug]` (omit slug for a picker) |
+| Resize the pet everywhere | `hermes pets scale <factor>` (e.g. `0.5`, clamped 0.1–3.0) |
+| Preview/animate | `hermes pets show [slug] [--state <s>] [--cycle] [--once] [--mode <m>] [--scale <f>]` |
+| Disable the pet | `hermes pets off` |
+| Remove an installed pet | `hermes pets remove <slug>` |
+| Diagnose setup | `hermes pets doctor` |
+
+`hermes pets show` flags:
+
+- `--state` — play a single state (`idle`, `wave`, `run`, `failed`, `review`,
+  `jump`).
+- `--cycle` — cycle through every state.
+- `--once` — play once instead of looping.
+- `--mode` — override the render protocol (`kitty`, `iterm`, `sixel`,
+  `unicode`, `auto`).
+- `--scale` — override the on-screen scale (`0` = use config).
+
+## `/pet` slash command
+
+Inside the CLI and TUI you can manage the pet without leaving the session:
+
+- `/pet` — toggle the pet on/off (adopts the first installed pet if none is
+  active).
+- `/pet list` — browse the gallery.
+- `/pet scale <factor>` — resize the pet everywhere (e.g. `/pet scale 0.5`).
+- `/pet <slug>` — adopt a specific pet.
+- `/pet off` — disable the pet.
+
+In the TUI, `/pet list` opens an interactive picker overlay; in the desktop app
+it opens the Cmd+K pet palette.
+
+## Desktop app
+
+In the desktop app you can manage the pet two ways:
+
+- **Cmd+K → "Pets…"** — browse, search, adopt, and toggle pets without leaving
+  the keyboard (mirrors the theme picker).
+- **Settings → Appearance** — the same gallery plus a **size slider** that
+  resizes the floating mascot live as you drag.
+
+Both adopt/toggle/resize the floating mascot in place — size changes apply
+instantly; adopting a new pet lights it up within a moment.
+
+### Pop-out overlay
+
+**Shift-click** the floating pet to pop it out into its own transparent,
+always-on-top desktop window. Out there it stays visible while Hermes is
+minimized (Codex-style), so a glance tells you what the agent is doing.
+
+Gestures once it's popped out:
+
+| Gesture | Action |
+| --- | --- |
+| **Drag** | Move the pet anywhere on screen, even outside the app. Its spot and in/out state persist across restarts. |
+| **Single-click** | Open a mini composer to send a prompt to the most recent session — without surfacing the app. |
+| **Double-click** | Toggle the app window: minimize it if it's up front, restore it if it's hidden. |
+| **Shift-click** | Pop the pet back into the window. |
+| **Mail icon** | Appears only when a turn finished while you were away; click to raise the app on the most recent thread (and mark it read). |
+
+Only the popped-out pet shows a **speech bubble** (`working…`, `thinking…`,
+`your turn`, …) — in-window the app itself is the surface, so the pet stays
+quiet there.
+
+The overlay is a pure puppet of the in-app pet — it carries no separate gateway
+connection and never appears in the dock or app switcher.
+
+## Configuration
+
+All settings live under `display.pet` in `config.yaml`:
+
+```yaml
+display:
+  pet:
+    enabled: false        # master on/off (true once you select a pet)
+    slug: ""              # active pet; empty = first installed
+    render_mode: auto      # auto | kitty | iterm | sixel | unicode | off
+    scale: 0.33           # master size knob (relative to native 192x208 frames)
+    unicode_cols: 0       # hard override for terminal width (0 = derive from scale)
+```
+
+- **`scale`** is the single master size knob. One number shrinks every surface:
+  the desktop canvas scales its pixels by it, and the CLI/TUI derive their
+  terminal column width from it. The half-block fallback clamps to a legibility
+  floor — it can't shrink as far as true-pixel kitty/GUI rendering without
+  turning to mush, so the same `scale` looks crisp under kitty but is floored in
+  half-blocks.
+- **`render_mode: auto`** detects kitty/iTerm2/sixel and falls back to unicode
+  half-blocks. Set it explicitly to force a protocol or `off` to disable
+  terminal rendering while keeping the pet on the desktop.
+- **`unicode_cols`** pins the terminal column width independently of `scale`;
+  leave it at `0` to derive width from `scale`.
+
+## Troubleshooting
+
+Run `hermes pets doctor` — it reports:
+
+- the pets directory and which pets are installed,
+- `display.pet.enabled`, `display.pet.slug`, and the resolved active pet,
+- the configured `render_mode`, the detected terminal graphics protocol, and the
+  effective mode for a TTY,
+- whether Pillow (used for sprite decoding) is importable.
+
+It prints `✓ ready` once a pet is installed, selected, enabled, and Pillow is
+available.
+
+Common gotchas:
+
+- A pet only shows once one is **installed AND selected** (`enabled: true`).
+- Inside a pipe/redirect (no TTY), terminal rendering is disabled by design.
+- The petdex npm CLI installs to `~/.codex/pets`; Hermes uses its own
+  profile-scoped `<HERMES_HOME>/pets/` instead — install through `hermes pets`.
+
+## See also
+
+- The [`petdex` skill](../skills/bundled/productivity/productivity-petdex.md)
+  lets the agent install and switch pets for you on request.

+
+:::info
+The following is the complete skill definition that Hermes loads when this skill is triggered. This is what the agent sees as instructions when the skill is active.
+:::
+
+# Petdex Skill
+
+Browse, install, and select animated "pet" mascots from the public
+[petdex](https://github.com/crafter-station/petdex) gallery. An installed pet
+reacts to agent activity (idle, running a tool, reviewing, error, done) across
+the Hermes CLI, TUI, and desktop app. This skill drives the `hermes pets` CLI
+and the `display.pet` config — it does not generate sprites.
+
+## When to Use
+
+- The user wants a desktop/terminal mascot or asks about "pets" / petdex.
+- The user wants to change, preview, or disable the active pet.
+- Diagnosing why a pet isn't showing (terminal graphics support, config).
+
+## Prerequisites
+
+- Network access to `petdex.dev` for the gallery/manifest (read-only, no auth).
+- Pillow (a core Hermes dependency) for sprite decoding — already installed.
+- For full-fidelity terminal rendering: a graphics-capable terminal (kitty,
+  Ghostty, WezTerm, iTerm2, or sixel). Otherwise a truecolor Unicode
+  half-block fallback is used automatically.
+
+## How to Run
+
+Use the `terminal` tool to run `hermes pets <subcommand>`.

+- `enabled` (bool) — master on/off.
+- `slug` (str) — active pet; empty = first installed.
+- `render_mode` — `auto` (detect) | `kitty` | `iterm` | `sixel` | `unicode` | `off`.
+- `scale` (float) — on-screen size of the native 192×208 frames (default 0.33,

Subject: [PATCH 006/244] fix(model_switch): route typed configured models off
 openai-codex (#45006)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A typed `/model <name>` where `<name>` is declared under `providers.<slug>` or
`custom_providers` — but typed while the current provider is a soft-accepting
one (e.g. `openai-codex`) — stayed on the current provider and was swallowed as
an unknown hidden Codex model, instead of routing to the provider that actually
declares it.

Add configured-provider exact-match detection (`_configured_provider_matches`)
and a new Step d.5 in `switch_model`: if the typed model is declared in
user/custom provider config, route to that provider BEFORE
`detect_provider_for_model()` guesses from static catalogs and BEFORE the
common-path validation lets a soft-accepting current provider swallow the name.

- Matching is exact (case-insensitive) against explicitly-declared model
  collections only (`models`, `model`, `default_model`) — never fuzzy/family.
- Same-provider declarer → keep current provider (canonicalize the id).
- Multiple declarers → fail clearly and ask for `--provider <slug>`.
- Single declarer → route there; for `providers.<slug>` user providers, set
  `explicit_provider` so the credential block resolves base_url/key from config.
- Step e (`detect_provider_for_model`) is gated off when `config_routed`.

The deliberately-supported openai-codex / xai-oauth hidden-model soft-accept
(#16172 / #19729) is left untouched: when nothing in config matches, detection
is a no-op.

Salvaged from #45442 by harjothkhara (authorship preserved).

Tests: tests/hermes_cli/test_model_switch_configured_provider_routing.py
(7 tests). Full model_switch suite: 214 passed.

Fixes #45006

+"""Regression tests for #45006: typed `/model <name>` resolution must route a
+model declared in user/custom provider config to that provider instead of
+leaving it on the current provider and soft-accepting it.
+
+Repro: with the current provider set to ``openai-codex``, typing
+``/model qwen3.5-4b`` (a model the user declares under ``providers.<slug>`` or
+``custom_providers``) showed ``Provider: OpenAI Codex`` — because typed
+detection only consulted static catalogs / OpenRouter, never the user's
+configured provider model lists, so the name stayed on Codex and was
+soft-accepted as an unknown hidden Codex model.
+
+The fix adds an exact-match configured-provider detection step in
+``switch_model`` that runs before ``detect_provider_for_model`` and before
+common-path validation.  These tests pin its precedence rules and prove the
+deliberately-supported Codex hidden-model soft-accept (#16172 / #19729) is left
+intact when nothing in config matches.
+
+Hermetic: the model-resolution chain is fully mocked (no network), mirroring

Subject: [PATCH 007/244] fix(cron): fail closed when an unpinned job's
 provider drifts from creation snapshot (#44585)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

An unpinned cron job follows the global default provider (config.yaml
model.default + resolve_runtime_provider). If that global state is changed
after the job is created — e.g. a temporary switch to a paid provider like
nous/claude-fable-5 — the job silently inherits it on its next tick and spends
real money. This is the reported $7.73 incident: a job created under a
free/default provider later inherited a temporary paid switch.

Fix (ask #1 only) preserves the legitimate "unpinned job should follow
model.default" use case by detecting *drift* rather than freezing the model:

- create_job (cron/jobs.py): for UNPINNED, agent-backed jobs (no explicit
  provider, not no_agent), snapshot the provider that resolution WOULD pick
  right now into a new optional `provider_snapshot` field, resolved via the
  same resolve_runtime_provider() path the ticker uses. Fail-open to None on
  any resolution error so job creation never breaks.

- run_job (cron/scheduler.py): right after runtime resolution, if the job has
  a provider_snapshot AND is unpinned AND the currently-resolved provider
  DIFFERS from the snapshot, fail closed for that run — make no paid call and
  deliver a loud, actionable alert naming both providers and telling the user
  to pin explicitly (`cronjob action=update job_id=.. provider=..`).

Back-compat: jobs with no snapshot (pre-existing jobs, no_agent jobs, or any
job whose creation-time resolution failed) behave exactly as before — the
guard only engages when a snapshot exists. Explicitly-pinned jobs (job.provider
set) are unaffected since they don't drift with global state.

Tests: tests/cron/test_cron_provider_pin.py covers snapshot-matches (runs),
snapshot-differs (fail closed, no agent constructed), no-snapshot back-compat,
None-snapshot back-compat, explicitly-pinned (runs regardless), plus create_job
snapshot capture/skip/fail-open. The fail-closed case is load-bearing (fails
without the guard).

Issue #44585 asks #2-4 (hard-stop a running job, gateway-stop containment,
fail-closed on provider mutation) are out of scope for this change.

+"""Provider-drift fail-closed guard for cron jobs (#44585).
+
+Background: an UNPINNED cron job follows the global default provider. If that
+global state is changed (e.g. a temporary switch to a paid provider like
+nous/claude-fable-5), the job would silently inherit it on its next tick and
+spend real money — the $7.73 incident.
+
+The fix has two halves:
+  - create_job() snapshots the provider resolution WOULD pick at creation into
+    job["provider_snapshot"] (only for unpinned, agent-backed jobs).
+  - run_job() fails closed when an unpinned job's CURRENTLY-resolved provider
+    differs from that snapshot: it skips the run, makes no paid call, and
+    delivers a loud actionable error.
+
+These tests exercise the full run_job path (real imports, mocked AIAgent +
+resolve_runtime_provider against a temp HERMES_HOME) and the create_job
+snapshot capture. They are load-bearing: without the guard, cases (b) call the
+agent and "succeed" instead of failing closed.

If the global default later changes, the job **fails closed**: it skips the run, makes no inference call, and sends an alert telling you to pin the provider/model explicitly (`cronjob action=update job_id=… provider=… model=…`) to proceed. This prevents an unattended job from silently inheriting a switch to a paid provider/model and spending money you didn't intend (#44585).

Subject: [PATCH 008/244] fix(mcp): skip killpg when child shares gateway's
 process group (#47134)

/reload-mcp -> shutdown_mcp_servers -> _kill_orphaned_mcp_children(include_active=True)
-> _send_signal -> killpg(pgid, SIGTERM). When a tracked MCP stdio child shares
the gateway's OWN process group, killpg delivers SIGTERM to the gateway itself,
firing its SIGTERM handler -> os._exit(0): /reload-mcp crashes the gateway.

Pre-compute the gateway's own pgid (os.getpgrp(), None on Windows/restricted)
and, in _send_signal, skip killpg when pgid == own pgid, falling through to the
per-pid os.kill path so the child is still reaped without self-signaling.

Adds a regression test (folded in) that pins the guard: with a tracked pgid
equal to the gateway's own pgid, killpg is never called for that pgid and the
per-pid kill fallback is used. Mutation-checked.

Subject: [PATCH 009/244] fix(tui): preserve live session identity across
 compression (#49041)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When a session rotates id on compression, _sync_session_key_after_compress()
re-anchored the session_key, approval-notify routing, yolo state, and slash
worker — but never moved the active-session lease, which stayed keyed to the
pre-compression id. And _find_live_session_by_key() matched live sessions on
the stale session_key, not the live agent's current agent.session_id. After
compression a resume/create path failed to recognize the existing live agent
and could build a SECOND live agent against the same DB continuation -> forked
lineage / cross-session message mixing.

- active_sessions.transfer_active_session(): move a lease in place to the new
  id under the exclusive file lock (no slot drop).
- gateway _transfer_active_session_slot(): call it inside
  _sync_session_key_after_compress(); on the rare fallback (entry pruned)
  RESERVE the new slot before releasing the old lease (reserve-before-release),
  so a concurrent gateway at the session cap cannot grab the freed slot in a
  release-then-reacquire window and leave this session with no lease; if the
  reserve fails, keep the existing lease (review fix).
- _session_lookup_key(): make live-session lookup authoritative on
  agent.session_id, wired into all stale-session_key consumers
  (_find_live_session_by_key, _session_live_item, _live_session_payload) —
  fixes the whole lookup class.

Subject: [PATCH 010/244] fix(telegram): wire platform_httpx_limits into
 general-pool HTTPXRequest (#31599)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PTB's HTTPXRequest builds its httpx.AsyncClient with
`limits = httpx.Limits(max_connections=connection_pool_size)` and no
keepalive tuning, so httpx's default keepalive_expiry=5.0 applies. Behind
an HTTP proxy (Cloudflare Warp etc.) a peer-initiated FIN can sit in
CLOSE_WAIT longer than that, leaking fds in the general request pool
(_request[1], which routes bot.send_message/set_my_commands) — the pool
_drain_polling_connections never resets. Telegram was the lone holdout
adapter not using the shared #18451 CLOSE_WAIT helper.

Wire gateway.platforms._http_client_limits.platform_httpx_limits() into
the httpx client across ALL THREE request-construction branches —
fallback-transport, proxy, and plain — via httpx_kwargs["limits"], which
PTB spreads last into its client kwargs so our tuned limits win. PTB's
connection_pool_size (max_connections) is preserved; only keepalive
behaviour is tightened (max_keepalive_connections + keepalive_expiry<5.0).

The fix is macOS-import-safe: no Linux-only socket TCP_KEEPIDLE/INTVL/CNT
constants at module scope (unlike the broken candidate which crashed on
import on the reporter's OS), and it patches the actual proxy path the
repro hits rather than TelegramFallbackTransport, which the proxy repro
never instantiates.

Adds a mutation-survivable behavior-contract test asserting every
HTTPXRequest built by connect() receives httpx_kwargs["limits"] with
keepalive_expiry < httpx's 5.0 default, across both the proxy and plain
branches. Reverting the limits wiring fails the test.

+"""Regression test for #31599 — Telegram general-pool CLOSE_WAIT fd leak.
+
+Background
+----------
+PTB's ``telegram.request.HTTPXRequest`` builds the underlying
+``httpx.AsyncClient`` with ``limits = httpx.Limits(max_connections=...)``
+and *no* keepalive tuning, so httpx's default ``keepalive_expiry=5.0``
+applies.  Behind an HTTP proxy (Cloudflare Warp etc.) a peer-initiated
+FIN can sit in ``CLOSE_WAIT`` longer than that, leaking fds in the
+general request pool (``_request[1]`` — the pool that routes
+``bot.send_message`` / ``set_my_commands``), which
+``_drain_polling_connections`` never resets.
+
+The fix wires the shared ``gateway.platforms._http_client_limits``
+``platform_httpx_limits()`` helper into *every* HTTPXRequest the adapter
+builds — the fallback-transport branch, the proxy branch, and the plain
+branch — so idle keepalive sockets drain aggressively.
+
+Contract asserted here (mutation-survivable)
+---------------------------------------------
+Every ``HTTPXRequest`` constructed by ``TelegramAdapter.connect()`` must
+receive ``httpx_kwargs["limits"]`` that is an ``httpx.Limits`` with a
+``keepalive_expiry`` strictly below httpx's 5.0 default and a positive,
+bounded ``max_keepalive_connections``.  Reverting the limits wiring (so
+HTTPXRequest falls back to PTB's default 5.0s keepalive) fails this test.

+"""Behavior contracts for incremental tool-call persistence (#49045).
+
+A destructive or process-terminating tool that runs during tool execution
+must not lose the just-executed assistant(tool_calls) block or the tool
+results that were produced before it fired.  These tests pin the contract:
+
+    1. run_conversation flushes the assistant tool-call turn to the session
+       DB BEFORE handing control to _execute_tool_calls (so a tool that
+       restarts/kills the process never orphans the tool-call block).
+    2. The SEQUENTIAL tool path flushes each tool result to the session DB
+       immediately after appending it — BEFORE the next tool dispatches.
+    3. The CONCURRENT tool path flushes each tool result in append order.
+
+These exercise the REAL production dispatch surfaces:
+
+    * sequential -> ``run_agent.handle_function_call`` (tool_executor ~1256/1298)
+    * concurrent -> ``agent._invoke_tool`` (tool_executor ~539)
+
+Mocking the genuine dispatch surface keeps the tests deterministic (no real
+``web_search`` / network) AND mutation-survivable: the ordering assertions
+read snapshots captured at flush time, so removing any production flush call
+makes the corresponding assertion fail.

Open-ended skill learning across every surface. /learn <free text> takes a
description of any source — a directory, a URL, the workflow you just walked
the agent through, or pasted notes — and the live agent gathers it with the
tools it already has (read_file/search_files, web_extract, the conversation,
the pasted text), then authors a SKILL.md via skill_manage following the
house authoring standards (<=60-char description, the standard section order,
Hermes-tool framing, no invented commands).

No engine, no model-tool footprint, works on any terminal backend (local,
Docker, remote): /learn builds a standards-guided prompt and hands it to the
agent as a normal turn.

- agent/learn_prompt.py: shared standards-guided prompt builder
- /learn registry entry (both surfaces) + CLI handler (inject onto input
  queue) + gateway handler (rewrite turn, fall through, /blueprint pattern)
- tui_gateway command.dispatch returns a send directive -> TUI + dashboard chat
- dashboard Skills page 'Learn a skill' panel (dir + URL + open-ended text)
  composes a /learn request and runs it in chat
- docs (slash-commands ref + skills feature page), 11 targeted tests

Inspired by OpenAI Codex's Record & Replay and the /learn concept from #47234
(dir-distillation engine); reworked to be open-ended and engine-free per
review.

+"""``/learn`` — build the standards-guided prompt that turns whatever the user
+described into a reusable skill.
+
+``/learn`` is open-ended. The user can point it at anything they can describe:
+a directory of code, an API doc URL, a workflow they just walked the agent
+through in this conversation, or pasted notes. This module builds ONE prompt
+that instructs the live agent to:
+
+  1. Gather the sources the user named, using the tools it already has
+     (``read_file`` / ``search_files`` for dirs, ``web_extract`` for URLs, the
+     current conversation for "what I just did", the user's text for pasted
+     material).
+  2. Author a single ``SKILL.md`` via ``skill_manage`` that follows the Hermes
+     skill-authoring standards (description <=60 chars, the modern section
+     order, Hermes-tool framing, no invented commands).
+
+There is no separate distillation engine and no model-tool footprint: the
+agent does the work with its existing toolset, so this works identically on
+local, Docker, and remote terminal backends. Every surface (CLI ``/learn``,
+gateway ``/learn``, the dashboard "Learn a skill" panel) calls
+:func:`build_learn_prompt` and feeds the result to the agent as a normal turn.
+"""

+# The house-style rules, distilled from AGENTS.md "Skill authoring standards
+# (HARDLINE)" and the hermes-agent-dev new-skill salvage reference. Embedded in
+# the prompt so the agent authors skills the way a maintainer would by hand.
+_AUTHORING_STANDARDS = """\
+Follow the Hermes skill-authoring standards exactly:
+
+Frontmatter:
+- name: lowercase-hyphenated, <=64 chars, no spaces.
+- description: ONE sentence, <=60 characters, ends with a period. State the
+  capability, not the implementation. No marketing words (powerful,
+  comprehensive, seamless, advanced). Do NOT repeat the skill name. If the
+  description contains a colon, wrap the whole value in double quotes.
+- version: 0.1.0
+- metadata.hermes.tags: a few Capitalized, Relevant, Tags.
+
+Body section order (omit a section only if it genuinely has no content):
+1. "# <Human Title>" then a 2-3 sentence intro: what it does, what it does NOT
+   do, and the key dependency stance (e.g. "stdlib only").
+2. "## When to Use" — bullet list of concrete trigger phrases.
+3. "## Prerequisites" — exact env vars, install steps, credentials.
+4. "## How to Run" — the canonical invocation, framed through Hermes tools.
+5. "## Quick Reference" — a flat command/endpoint list, no narration.
+6. "## Procedure" — numbered steps with copy-paste-exact commands.
+7. "## Pitfalls" — known limits, rate limits, things that look broken but aren't.
+8. "## Verification" — a single command/check that proves the skill worked.
+
+Hermes-tool framing (this is what makes it a skill, not shell docs):
+- Frame running scripts as "invoke through the `terminal` tool".
+- Use `read_file` (not cat/head/tail), `search_files` (not grep/find/ls),
+  `patch` (not sed/awk), `web_extract` (not curl-to-scrape),
+  `vision_analyze` for images. Reference these tools by name in backticks.
+- Do NOT name shell utilities the agent already has wrapped.
+
+Quality bar:
+- Prefer exact commands, endpoint URLs, function signatures, and config keys
+  that appear VERBATIM in the source. NEVER invent flags, paths, or APIs — if
+  you didn't see it in the source, don't write it.
+- Keep it tight and scannable: ~100 lines for a simple skill, ~200 for a
+  complex one. Don't re-paste the source docs.
+- Don't write a router/index/hub skill that only points at other skills.
+- Larger scripts/parsers belong in a `scripts/` file (add via
+  `skill_manage` write_file), referenced from SKILL.md by relative path — not
+  inlined for the agent to re-type every run."""

+## Learning a skill from sources (`/learn`)
+
+`/learn` is the fast way to turn something you already know — or a pile of
+reference material — into a reusable skill, without hand-writing the
+`SKILL.md`. It is open-ended: point it at *anything you can describe* and the
+agent gathers the material with the tools it already has, then authors a skill
+that follows the [house authoring standards](#skillmd-format) (≤60-char
+description, the standard section order, Hermes-tool framing, no invented
+commands).
+
+```bash
+# A local SDK or doc directory — read with read_file / search_files
+/learn the REST client in ~/projects/acme-sdk, focus on auth + pagination
+
+# An online doc page — fetched with web_extract
+/learn https://docs.example.com/api/quickstart
+
+# The workflow you just walked the agent through in this conversation
+/learn how I just deployed the staging server
+
+# Pasted notes / a described procedure
+/learn filing an expense: open the portal, New > Expense, attach the receipt, submit
+```
+
+Because the live agent does the sourcing, `/learn` works the same in the CLI,
+the messaging gateway, the TUI, and the dashboard — and on any terminal backend
+(local, Docker, remote), since there is no separate ingestion engine. In the
+**dashboard**, the Skills page has a **Learn a skill** button that opens a panel
+with a directory field, a URL field, and an open-ended text box; it composes a
+`/learn` request and runs it in chat.
+
+There is no model-tool footprint: `/learn` builds a standards-guided prompt and
+hands it to the agent as a normal turn. The agent saves the result with the
+`skill_manage` tool, so the [write-approval gate](#gating-agent-skill-writes-skillswrite_approval)
+applies if you have it on.
+

Subject: [PATCH 014/244] fix(gateway): preserve _session_tasks on guard
 mismatch to enable stale lock healing (#48300)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_session_task_is_stale() failed to detect a stale session lock when the owner
task completed and cleaned _session_tasks (del in _process_message_background's
finally) but _active_sessions was NOT released because _release_session_guard
skipped on a guard mismatch (a concurrent reset/new command or drain handoff
swapped _active_sessions[key] to a different guard). With no owner task left to
inspect, _session_task_is_stale reported 'not stale', the orphaned guard was
never healed, and the session deadlocked permanently — later messages received
but never dispatched.

Reorder the finally cleanup to release-then-conditional-delete: release the
guard first, then drop the _session_tasks entry ONLY if the guard was actually
released (session_key no longer in _active_sessions). On a guard mismatch the
done-task entry survives, so the on-entry self-heal (_session_task_is_stale ->
_heal_stale_session_lock) detects the stale lock and clears it on the next
inbound message.

Extracted the cleanup into a callable _cleanup_finished_session_task() helper so
the regression test drives the REAL production code path rather than a copy of
its logic (the original test inlined the fixed logic and passed regardless of
the production order — mutation-verified the rewritten tests now fail on the
buggy del-first order). Added a positive-path test (guard matches -> release +
delete) so both branches are pinned.

Subject: [PATCH 016/244] fix(gateway): prevent double dispatch of Discord
 messages via thread-starter dedup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When _auto_create_thread() creates a thread from a user message via
message.create_thread(), Discord fires a second MESSAGE_CREATE event
for the 'thread starter message'.  That starter message carries
message.id == thread.id and may arrive with type=default instead of
type=21 (thread_starter_message), so the existing type filter in
on_message does not catch it — triggering a second call into
_handle_message and thus a second agent run and response.

Fix: after _auto_create_thread succeeds and returns a thread, pre-seed
the dedup cache with str(thread.id) via self._dedup.is_duplicate().
The dedup cache is the same TTL-based MessageDeduplicator that already
guards against Discord RESUME event replays.  Calling is_duplicate()
marks the ID as seen; when the duplicate thread-starter MESSAGE_CREATE
arrives, on_message's guard returns True and the event is dropped.

This is a minimal, targeted fix:
- No new state: reuses the existing _dedup instance
- No timing/race: the pre-seed happens synchronously inside the async
  _handle_message, before the thread-starter event can be dispatched
- Scoped: only fires when auto-threading is enabled AND thread creation
  succeeds (thread object is not None)

Also adds tests in tests/gateway/test_discord_double_dispatch.py
covering the pre-seed behaviour, failure modes (thread creation fails,
auto-thread disabled), and dedup cache integrity.

Closes #51057

+"""Detect when the gateway is running stale code after a hot ``git pull``.

+The gateway is a single long-lived process; its ``sys.modules`` is frozen at
+boot. If the checkout is updated underneath it (a manual ``git pull``, or the
+window before ``hermes update``'s graceful restart fires), a first-time lazy
+import on a new code path can resolve a freshly-pulled consumer module against a
+stale cached dependency -> ImportError (see
+``tests/test_stale_utils_module_import.py`` for the exact failure).
+
+We snapshot the checkout revision at gateway startup and compare on demand, so
+risky callers (e.g. ``/model`` switching) can refuse with a clear "restart the
+gateway" message instead of crashing on a cryptic import error.
+
+If the revision can't be read (non-git install, IO error), the boot snapshot
+stays ``None`` and skew detection no-ops — it never produces a false positive.

+"""Regression for the stale-``utils``-module ImportError after a hot ``git pull``.
+
+Real incident (gateway session 1518671026962174144)::
+
+    Sorry, I encountered an error (ImportError).
+    cannot import name 'env_float' from 'utils' (~/.hermes/hermes-agent/utils.py)
+
+Mechanism:
+
+1. A long-running gateway/agent process imported ``utils`` BEFORE ``env_float``
+   existed (added in 06ca1e99, 2026-06-20 14:00). The cached module object in
+   ``sys.modules`` therefore has no ``env_float`` attribute.
+2. ``hermes update`` ran ``git pull``, updating ``utils.py`` (now defining
+   ``env_float``) and ~22 consumer modules (now doing ``from utils import
+   env_float``) on disk -- WITHOUT restarting the process.
+3. Switching the live session's model (anthropic/opus -> opencode/glm) forced the
+   FIRST import of a consumer module on the new provider's code path. Its
+   top-level ``from utils import env_float`` resolved against the STALE cached
+   ``utils`` -> ImportError. The path in parentheses is the consumer-reported
+   ``utils.__file__`` on disk (which *does* define ``env_float``), which is why
+   the error is so confusing: the file on disk is fine, the in-memory module is not.
+
+``hermes_cli/main.py`` (the ``hermes update`` flow, ~line 9326) already
+acknowledges this exact hazard -- "source files on disk are newer than cached
+Python modules in this process" -- and reloads ``hermes_constants`` after the
+pull, but NOT ``utils``. Any ``utils`` consumer added in the same release stays
+exposed until the process restarts.
+
+The messaging client (Discord/Telegram/Feishu/...) is incidental: the trigger is
+a fresh import on a stale process, not the platform. We assert that below by
+reproducing the failure with the Discord adapter's exact import line.

Subject: [PATCH 018/244] fix(windows): harden gateway scheduled task (#45610)

* fix(windows): harden gateway scheduled task

* fix(windows): launch gateway scheduled task via console-less wscript

The Scheduled Task ran the gateway through cmd.exe, which allocates a
console. During logon Windows broadcasts CTRL_CLOSE_EVENT to console
process groups, reaping cmd.exe and the half-initialized gateway with
STATUS_CONTROL_C_EXIT (0xC000013A) - which Task Scheduler treats as a
user cancel, so RestartOnFailure never fires and the gateway vanishes on
every reboot (issue #45599 root cause #1).

Add a console-less .vbs launcher (wscript.exe -> pythonw.exe, both
GUI-subsystem) mirroring the gateway.cmd env + argv, and point the task
action at it. The .cmd stays for the Startup-folder fallback and /Run.

The gateway half of the going-idle/buffered-flip primitive (scale-to-zero
PRIMITIVE, not the behaviour). Integrates with the EXISTING drain transition:

- ws_transport: `go_idle()` sends `going_idle` + awaits the connector's
  `going_idle_ack` (connector-authoritative flip-then-ack, Q-5.3c — stays
  serving until the ack so nothing is lost in the flip window); acks a buffered
  inbound (bufferId present) via `inbound_ack` after the handler runs
  (drain-without-dup on the delivery leg); NET-NEW reconnect loop re-dials +
  re-handshakes after an unexpected close (off by default, on in production).
- adapter: emits `going_idle` from its existing `disconnect()` drain seam before
  tearing down the socket; best-effort + guarded (never blocks shutdown).
- transport Protocol + contract doc §3.2 document the 3 new frames.

+6 relay tests (124 pass). NOT in scope: the autonomous idle timer / machine
suspend / NAS health model (deferred behaviour). Ben's relay-adapter solo lane.

+### 3.2 Going-idle / buffered-flip primitive (§5.3)
+
+A scale-to-zero PRIMITIVE (not the behaviour — nothing here decides to sleep or
+suspends a machine; a later workstream consumes these frames). It lets a gateway
+enter a drain/idle transition without losing inbound that arrives while it is
+gone, by making the connector buffer for that instance and replay on reconnect.
+
+Three frames (all keyed by the connection's **authenticated** per-instance id —
+read off the stored secret record at the WS upgrade, never asserted in a frame):
+
+- `{"type":"going_idle"}` (gateway → connector) — emitted as part of the
+  gateway's EXISTING drain transition (the adapter sends it before tearing down
+  the socket). Asks the connector to flip this instance to **buffered-only**.
+- `{"type":"going_idle_ack"}` (connector → gateway) — the connector has flipped:
+  live delivery has stopped and subsequent inbound for this instance buffers
+  durably. The gateway **stays serving until this ack** (so an event landing in
+  the flip window is delivered live, not lost — the same SUBSCRIBE-before-serve
+  ordering discipline as the bus). Only after the ack is it safe to close.
+- `{"type":"inbound_ack", "bufferId"}` (gateway → connector) — durable receipt of
+  a buffered `inbound` delivery (which carries its `bufferId`) replayed on
+  reconnect. The connector acks the buffer entry only after this, giving
+  drain-without-dup on the **delivery leg**: an instance that dies mid-drain
+  redelivers exactly the unacked tail; an acked entry never redelivers.
+
+**Buffer + drain.** While flipped, the connector appends inbound to a durable
+per-instance delivery-leg buffer (`delivery:<instanceId>`) instead of pushing it
+live. On the gateway's **reconnect** (a NET-NEW reconnect loop re-dials +
+re-handshakes after an unexpected close), the new handshake triggers the
+connector to drain that backlog over the new socket **in order, ack-gated**,
+then clear the flip so live delivery resumes. This reuses the same
+`drainWithoutDup` machinery as the Discord→connector ingest leg, applied to the
+connector→gateway delivery leg. Connector-authoritative throughout: a gateway can
+only flip/drain ITS OWN instance.
+
+> NOT in scope (deferred behaviour): the autonomous idle timer that DECIDES to
+> drain, the actual machine suspend, and the NAS suspended-health model. The
+> primitive is "when the gateway drains, relay flips to buffered + replays on
+> reconnect, with no loss/dup"; WHAT triggers the drain is out of scope.

Subject: [PATCH 020/244] harden(pets): host-pin asset downloads + sanitize
 slug paths

install_pet now refuses spritesheet/pet.json URLs that aren't on a petdex
host (matching thumbnail_png's existing _is_petdex_host guard), so a
spoofed manifest can't redirect a download at an arbitrary host. Slugs
are normalized to a single path segment before indexing into pets_dir(),
closing a path-traversal vector in load_pet/remove_pet/install_pet.

Register a per-instance wakeUrl and forward it to the connector at
self-provision so a suspended gateway can be poked awake when buffered
work arrives (pairs with the connector-side WakePoker).

- relay_wake_url() resolver (env GATEWAY_RELAY_WAKE_URL, then
  gateway.relay_wake_url in config.yaml), mirroring relay_instance_id()
- thread wake_url through _post_provision (adds wakeUrl to the body only
  when set) + self_provision_relay (resolve, forward, log)
- hermes gateway enroll --wake-url <url> persists GATEWAY_RELAY_WAKE_URL
- document the §5.2 wake poke in relay-connector-contract.md §3.3
- tests: relay_wake_url resolution (env/config/absent), provision
  forwarding, body-only-when-set (6 new; 130 relay tests pass)

The actual reconnect+drain on wake is Unit B's loop; this unit only
wires the wake SIGNAL. Opt-in: absent wakeUrl => connector never pokes.

+### 3.3 Wake poke (§5.2)
+
+The other half of the sleep/wake loop: how a SUSPENDED gateway finds out it has
+buffered work waiting. A PRIMITIVE — nothing here suspends a machine; it wires
+the wake SIGNAL so a future scale-to-zero behaviour layer can rely on "buffered
+⇒ wake poked."
+
+- **Registration.** The gateway registers a **wake URL** at enroll/provision —
+  any reachable URL the connector can GET to wake it (a Fly autostart hostname,
+  a dashboard host). Self-hosted: `hermes gateway enroll --wake-url <url>` (or
+  `GATEWAY_RELAY_WAKE_URL` / `gateway.relay_wake_url`). Managed/NAS: stamped into
+  the container env beside `GATEWAY_RELAY_URL`. Forwarded in the
+  `/relay/provision` body as `wakeUrl` and stored per-instance on the connector's
+  secret record (gateway-asserted but safely scoped — same posture as
+  `instanceId`; the org/tenant stays token-verified, so a gateway can only
+  register a wake target for ITS OWN instance). DISTINCT from the retired
+  `gatewayEndpoint`: a **poke target**, not a delivery target.
+- **The poke.** When a buffered-only (going-idle) destination receives its FIRST
+  buffered event, the connector issues a **payload-free, unsigned GET** to that
+  instance's registered `wakeUrl`, **directly** (NOT NAS-mediated — relay stays
+  NAS-independent). It carries no tenant data and no inbound: it only says "you
+  have buffered work, reconnect." Tenant authority is re-established the normal
+  way when the gateway re-dials (the authenticated WS upgrade), so a leaked/
+  guessed wake URL can at worst cause a spurious reconnect of ITS OWN instance.
+  Rate-limited per instance (one poke per cooldown window, not per event), and
+  best-effort — a failed poke is swallowed; the gateway still drains whenever it
+  next reconnects on its own. No new frame: the wake is an out-of-band HTTP GET,
+  not a relay-WS message (the socket is down — that's the whole point).
+
+> NOT in scope (deferred behaviour): the actual machine suspend (Fly
+> `autostop:"suspend"`) and the autonomous idle timer that decides to sleep. The
+> primitive is "buffered event for a sleeping instance ⇒ its wakeUrl gets poked";
+> WHAT makes the instance sleep (and wake-to-serve) is the behaviour layer.

Subject: [PATCH 023/244] fix(update): reuse an existing PATH uv on Termux
 before pip

_ensure_uv_for_termux only checked resolve_uv() (the managed
$HERMES_HOME/bin/uv) before falling back to pip, so a uv installed via
`pkg install uv` lives on PATH but is invisible to the helper. Combined
with the cherry-picked wheel-only fallback, a Termux user with no managed
uv still hit `pip install uv`, which has no Android wheel and tried to
source-build the Rust crate, OOM-killing low-memory devices.

Probe shutil.which("uv") right after the Termux guard and reuse it before
pip. Add a regression test that keeps resolve_uv() returning None while a
uv exists on PATH and asserts pip is never invoked.

The contract already documents the scale-to-zero PRIMITIVES (§3.2 going-idle/
buffered-flip, §3.3 wake poke) and what's out of scope. This adds the missing
half: the contract FROM the primitives TO the behaviour layer — the guarantees
a separate scale-to-zero workstream must honour to consume them safely (register
a wakeUrl before suspend; drain+ack before teardown; keep the reconnect loop
live; treat suspended != down in the health model; don't assume exactly-once/
prompt wake; suspend only when genuinely idle, composing with the existing drain
machine). Docs-only; lets the independent scale-to-zero stream build against a
written contract instead of re-reading the connector.

+### 3.4 Obligations on a future scale-to-zero behaviour layer
+
+§3.2 and §3.3 ship the **primitives**; this section is the **contract a separate
+scale-to-zero behaviour workstream must honour to consume them safely.** It owns
+the *decision* to suspend, the actual machine suspend, and the platform/health
+model — none of which live here — but it MUST hold these guarantees, which the
+primitives assume:
+
+1. **Register a `wakeUrl` before the instance can ever be suspended.** A
+   suspended instance with no registered `wakeUrl` is a black hole — buffered
+   inbound never triggers a poke, so it sleeps through its own traffic until
+   something else reconnects it. The behaviour layer MUST ensure a reachable
+   wake target is registered (self-hosted: `--wake-url`; managed: stamped) as a
+   precondition of allowing suspend. A wake URL that is unreachable while the
+   machine is suspended (e.g. points at the suspended machine itself with no
+   platform autostart in front) is equivalent to none.
+2. **Drain through `going_idle` → await `going_idle_ack` BEFORE tearing down the
+   socket or suspending.** Never suspend with an un-acked flip in flight. The
+   ack is the connector's confirmation that delivery for this instance is now
+   buffered-only; a machine that suspends after sending `going_idle` but before
+   the ack can drop the inbound that races the flip. The gateway already gates
+   socket teardown on the ack (Q-5.3c); the suspend step MUST sit *after* a
+   clean drain completes, not race it.
+3. **Keep the NET-NEW reconnect loop live as a precondition of suspend.** The
+   wake→drain contract is "poke ⇒ the gateway re-dials ⇒ the connector drains on
+   the reconnect handshake." If the reconnect loop is disabled, a poke lands on a
+   machine that never re-dials and the buffer strands. The behaviour layer must
+   not suspend an instance whose relay transport won't reconnect on wake.
+4. **Treat suspended ≠ down in the health model (Q-5.3b).** A suspended instance
+   is healthy-asleep, not failed. The health/monitoring layer MUST distinguish
+   the two (e.g. via the platform machine-state) so a suspended instance is not
+   restarted, alerted on, or reaped as unhealthy — that would defeat the suspend
+   and can race the wake/drain.
+5. **The wake poke is best-effort and rate-limited — do not assume exactly-once
+   or immediate wake.** At most one poke per cooldown window per instance, and a
+   failed poke is swallowed. The behaviour layer must not rely on the poke as a
+   guaranteed/prompt signal; correctness still rests on "the gateway drains
+   whenever it next reconnects." A belt-and-suspenders wake (e.g. a scheduled
+   job that also reconnects) is the behaviour layer's call, not the primitive's.
+6. **Suspend only when genuinely idle — and idle is connector-observable, not
+   gateway-guessed.** WHAT counts as idle (no in-flight turn + no inbound for N
+   min) is the behaviour layer's policy, but it must compose with the existing
+   drain machinery (`gateway_state` running→draining) rather than introduce a
+   parallel relay-only idle path — the same integration constraint §3.2 places
+   on `going_idle`.
+
+These are guarantees the behaviour layer OWES the primitives; the primitives owe
+the behaviour layer only what §3.2/§3.3 already specify (a flip-on-going_idle,
+a durable per-instance buffer + ack-gated reconnect drain, and a poke on the
+first buffered event for a flipped instance).

Subject: [PATCH 026/244] fix(installer): re-resolve Python fallback at venv
 stage on Windows (#50769)

The Windows installer runs each -Stage NAME in its own powershell.exe under
Hermes-Setup.exe. Test-Python records a detected fallback (e.g. 3.12 when 3.11
is absent) via an in-memory $script:PythonVersion = $fallbackVer mutation,
which dies with the python stage's process. The fresh venv stage starts with
$PythonVersion back at its "3.11" default, so it logged "Creating virtual
environment with Python 3.11..." and ran uv venv venv --python 3.11, failing
with exit 2 on machines that only had the fallback installed.

Add a cross-process-safe Resolve-AvailablePythonVersion helper (preferring the
requested version, then the shared $PythonFallbackVersions list, probed via
uv python find) and call it at the top of Install-Venv before creating the
venv. Test-Python's fallback loop now iterates the same shared constant so
detection and venv creation can't drift.

Source-level regression guard (the script only runs on Windows, so there's no

Install-Venv re-resolves the interpreter before the venv-creation line, and
that Test-Python and the resolver share the single $PythonFallbackVersions

+"""Regression: the Windows installer must honor its Python fallback at venv time.
+
+A user on Windows 11 reported (#50769) that the installer correctly detected a
+Python 3.12 fallback when 3.11 was absent::
+
+    [OK] Found fallback: Python 3.12.8
+    ...
+    -> Creating virtual environment with Python 3.11...
+
+and then failed with ``Failed to create virtual environment (uv venv exited
+with 2)``.
+
+Root cause: ``Test-Python`` records the fallback via an in-memory
+``$script:PythonVersion = $fallbackVer`` mutation, but under Hermes-Setup.exe
+each ``-Stage NAME`` runs in its *own* fresh ``powershell.exe`` process.  The
+``venv`` stage therefore starts with ``$PythonVersion`` back at its ``"3.11"``
+default, so ``uv venv venv --python 3.11`` runs on a machine that has no 3.11.
+
+The fix re-resolves the interpreter inside ``Install-Venv`` (via the
+cross-process-safe ``Resolve-AvailablePythonVersion`` helper) before creating
+the venv, so the venv stage uses whatever interpreter is actually present.
+These tests lock that contract at the source level (the script only runs on

Subject: [PATCH 031/244] fix(photon): intercept console.log so 'stream
 interrupted' bursts escalate

spectrum-ts routes stream telemetry through @photon-ai/otel's createLogger,
which sends severity>=ERROR to console.error and WARN/INFO to console.log.
The two lines the health monitor keys off land on different channels:
log.error("stream persistently failing") -> console.error (caught), but
log.warn("stream interrupted; reconnecting") -> console.log (was missed).

The original interception patched console.error only, so the recovering->
degraded escalation counter never saw the interrupt bursts that are the
primary silent-inbound symptom. Verified live against spectrum-ts 3.1.0 +
@photon-ai/otel: 3 real log.warn('stream interrupted') calls now escalate
to degraded -> process.exit(75) -> adapter reconnect.

Adds a shared classifyStreamLog() fed by both console.error and console.log,
plus a regression test asserting both channels are intercepted.

Subject: [PATCH 033/244] test(docker): assert boot migration keeps .env
 byte-identical across reboots

Adds the #51579 regression test the issue asked for: run the real
docker_config_migrate.py boot path twice (host-reboot scenario under
--restart unless-stopped) and assert $HERMES_HOME/.env survives
byte-for-byte and the second boot is a no-op (no re-migration, no new
backup). Exercises real migrate_config + real file I/O via subprocess.

Subject: [PATCH 034/244] fix(cron): tell the user TUI/CLI cron jobs are
 local-only at create time (#51683)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

deliver=origin (or omitted) from a TUI or classic-CLI session produces a
job with origin=null, because those sessions never populate the
HERMES_SESSION_PLATFORM/CHAT_ID context vars that _origin_from_env reads.
The scheduler then resolves no delivery target and skips delivery — the
job runs and saves output to last_output, but nothing reaches the user
and they only find out by polling cronjob(action='list') (#51568).

This is by design (local sessions have no live-delivery channel), so the
fix surfaces it instead of silently dropping the intent:

- cronjob create now appends an informational notice to its result when
  a created job resolves to zero delivery targets and the user did not
  explicitly ask for deliver='local'. The check uses the scheduler's own
  _resolve_delivery_targets so it accounts for origin, home channels,
  'all', and explicit platform targets — no false positives.
- PLATFORM_HINTS gains a 'tui' entry (the TUI had none) and the 'cli'
  hint now states that cron jobs from these sessions are local-only and
  that deliver must target a gateway-connected platform to notify the
  user. This stops the agent promising a delivery that never happens.

No scheduler/delivery behavior change; no new env var; cron isolation
invariant untouched.

Subject: [PATCH 035/244] fix(config): write config.yaml as UTF-8 to stop
 emoji/personality corruption (#51676)

atomic_yaml_write (and two sibling config writers) called yaml.dump
without allow_unicode=True. The default personalities shipped in cli.py
contain emoji/kaomoji, so PyYAML escaped astral-plane chars as 8-digit
\\UXXXXXXXX sequences inside multi-line double-quoted strings wrapped
with \\ line-continuations. Stricter/non-PyYAML parsers, editors, and
hand-edits break that structure into unclosed quotes, failing the whole
config parse -> silent fallback to defaults -> custom_providers lost.

Add allow_unicode=True to the canonical writer plus tui_gateway/server.py
and the telegram adapter's atomic config write so config is written as
readable UTF-8 with no escape/fold artifacts.

Fixes #51356

Subject: [PATCH 037/244] fix(gateway): actively reap no-systemd gateway orphan
 before restart
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Builds on @wgu9's runtime-tracking fix: now that find_gateway_pids() can
see a no-supervisor `gateway restart` runtime, have stop_profile_gateway()
fall back to an orphan-aware, profile-scoped reap (SIGTERM then SIGKILL)
when the pidfile/runtime record is missing or stale. Closes the duplicate-
accumulation path in #51325 — a follow-up restart now kills the prior
orphan instead of stacking another listener on :8644. Gated on
not supports_systemd_services() so a transient `gateway restart` argv on
supervised hosts is never killed.

Also adds the AUTHOR_MAP entry for the salvaged contributor.

Subject: [PATCH 038/244] fix(tui): stop a cwd package named utils/proxy/ui
 from crashing the gateway child (#51693)

Launching Hermes from a directory that ships its own top-level package with a
Hermes-internal name (utils/, proxy/, ui/) crashed the gateway/TUI child with
an ImportError (exit 1, crash loop): from utils import atomic_replace resolved
to the user's package.

tui_gateway/entry.py already stripped the relative cwd forms ('' / '.'), but
the launch dir also reaches sys.path as its own ABSOLUTE path (venv activation
or a project that adds itself to PYTHONPATH), which the strip missed and which
sat ahead of the Hermes root.

Centralize a hardened guard in hermes_bootstrap.harden_import_path(): drop the
relative forms AND force the Hermes source root to the front even when an
absolute cwd entry is present. Wire it into tui_gateway/entry.py and
acp_adapter/entry.py (both spawn into arbitrary cwds); hermes_cli/main.py and
gateway/run.py already insert the root at front. gatewayClient.ts now also
exports HERMES_PYTHON_SRC_ROOT for defense in depth.

+
+    Hermes ships top-level modules with common names (``utils``, ``proxy``,
+    ``ui``).  Python always seeds ``sys.path`` with the current directory, so
+    launching an entry point from a project that has its own ``utils/`` package
+    makes ``from utils import ...`` resolve to the *user's* package and crash
+    with an ImportError before the gateway can even start.
+
+    The current directory reaches ``sys.path`` two ways, and a complete guard
+    has to handle both:
+
+      - As the empty string ``""`` (or ``"."``) that Python inserts at
+        ``sys.path[0]`` for ``-m`` / script launches.
+      - As its own *absolute* path, when a venv activation or a project that
+        adds itself to ``PYTHONPATH`` puts the directory there explicitly.
+
+    We drop the relative forms outright, then force the real Hermes source root
+    to the front — relocating it ahead of any absolute cwd entry rather than
+    only inserting when absent, so an absolute cwd path can't keep winning.
+
+    ``src_root`` defaults to the directory this module lives in, which is the
+    repository root for every shipped entry point, so the guard is
+    self-sufficient and does not depend on the spawner exporting an env var.

Subject: [PATCH 039/244] feat(cron): warn when gateway not running on cron
 create/list (#51696)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The cron ticker only runs inside the gateway (_start_cron_ticker); there
is no standalone cron daemon. When the gateway isn't running, next_run_at
passes but jobs never fire and last_run_at stays null — and manual
'hermes cron run' (which bypasses the ticker) appears to work, masking
the real cause. This is the most common cron support report (#51038).

cron list already warned; extend the same warning to cron create (the
moment the user is most likely to hit this) via a shared helper, and add
a pointer to 'hermes cron status'. Silent when a gateway is running, so
the gateway /cron path is unaffected.

Subject: [PATCH 040/244] fix(cron): anchor naive schedule timestamps to
 configured timezone (#51695)

A naive ISO timestamp (e.g. 2026-06-22T20:07:00) was anchored to the
server's local timezone via dt.astimezone(), but the due-check
(get_due_jobs -> _hermes_now()) runs in the CONFIGURED Hermes timezone.
When the two diverge (cloud host on UTC with a different timezone: set,
or vice-versa) the stored instant lands hours off the user's wall-clock
intent, so one-shots never become due and recurring jobs fire at the
wrong time. The ticker stays healthy (heartbeat + success markers fresh)
because every tick finds nothing due, matching the silent no-fire in #51021.

Anchor naive timestamps to _hermes_now().tzinfo so '20:07' means 20:07 on
the same clock the scheduler checks against. The legacy _ensure_aware path
still treats already-stored naive values as server-local for back-compat.

Fixes #51021

Subject: [PATCH 041/244] fix(gateway): exit 78 (EX_CONFIG) on fatal startup
 errors, s6 finish script stops restart loop
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Profiles without their own messaging token inherit the default
profile's token via os.getenv, hit a token collision, and exit with
startup_failed.  s6 restarts them immediately, creating ~30MB tirith
sandbox dirs in /tmp each cycle — filling the disk in hours (#51228).

Changes:
- gateway/restart.py: add GATEWAY_FATAL_CONFIG_EXIT_CODE = 78
- gateway/run.py: set exit_code=78 on non-retryable startup errors
  (token collision, no platforms)
- hermes_cli/service_manager.py: add _render_finish_script() that
  translates exit 78 → exit 125 (s6 permanent failure)
- hermes_cli/container_boot.py: write finish script alongside run
  script during profile registration

The s6 finish script pattern follows docker/s6-rc.d/dashboard/finish.

Closes #51228

Subject: [PATCH 042/244] fix(gateway): propagate fatal-config exit code
 through start_gateway clean-exit path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The contributor PR stamped runner._exit_code=78 on non-retryable startup
errors, but start_gateway()'s clean-exit branch returned True before the
SystemExit(runner.exit_code) site, so main() exited 0. The s6 finish
script's [ "$1" = "78" ] check never matched and s6 crash-looped the
gateway anyway — the fix was dead as shipped (#51228).

Honor runner.exit_code in the clean-exit branch: raise SystemExit(code)
when set, else return True (normal /restart clean exit). Add a
start_gateway()-level test that asserts process-level SystemExit(78)
propagation — the gap the PR's object-level test missed — plus exit_code
on the existing _CleanExitRunner mocks.

Subject: [PATCH 044/244] fix(profiles): detect a separate-process gateway in
 profile status
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The dashboard Profiles view showed "Gateway stopped" for a gateway that
is in fact running — while the sidebar status strip and `hermes gateway
status` (CLI) both correctly showed it running. Reported on v0.17.0
running the gateway + dashboard in one Docker container.

Root cause: three liveness surfaces with three detection strengths, all
reading the same `gateway.pid`:

  - `hermes gateway status` -> find_gateway_pids() (process-table scan)
  - sidebar /api/status     -> get_running_pid() + gateway_state.json PID
                               fallback + health-URL probe
  - Profiles view           -> _check_gateway_running() = get_running_pid()
                               ONLY, no fallback

`get_running_pid()` short-circuits to None the moment the runtime lock
(`gateway.lock`) doesn't register as held by the *calling* process —
which is always true when the reader is a separate process from the
gateway (the dashboard is its own s6 service in the container), and also
for any launch-service-managed gateway that left a fresh
`gateway_state.json` but no live PID file. So the Profiles view alone
reported the live gateway as stopped.

Fix: give _check_gateway_running the same fallback the sidebar already
has — after the pid-file/lock check misses, validate the PID recorded in
that profile's gateway_state.json against the live process table via the
existing get_runtime_status_running_pid(). read_runtime_status() gains an
optional path arg so a profile's state file can be read without mutating
the process-global HERMES_HOME (preserving the contextvar-based profile
isolation the dashboard relies on). Backward compatible: every existing
caller passes no argument.

Tests: a regression test that fails pre-fix (live gateway, lock check
returns None -> must still report running) and a guard test that a
'stopped' state file is never reported running even with a live PID.

Subject: [PATCH 046/244] fix(cron): complete plugins.cron_providers rename in
 2 missed test files
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

uperLu's #50958 renamed plugins/cron → plugins/cron_providers but left
two test files patching the now-gone plugins.cron.chronos.verify path,
which would fail collection. Point them at plugins.cron_providers.*.
Add uperLu to release.py AUTHOR_MAP.

Subject: [PATCH 047/244] fix(dashboard): serve uvicorn on SelectorEventLoop on
 Windows (#50641) (#51717)

On Windows, start_server() served uvicorn via a bare asyncio.run(_serve()),
which uses the default ProactorEventLoop. uvicorn's socket-serving stack
assumes a SelectorEventLoop on win32 (uvicorn/loops/asyncio.py forces it, and
uvicorn.Server.run threads config.get_loop_factory() into its runner for
exactly this reason). Driving uvicorn on the proactor loop makes
server.startup() bind a socket that never accepts: the dashboard and desktop
backend print "Skipping web UI build" then hang forever with the port
LISTENING but no TCP handshake completing.

Fix is win32-scoped to keep the blast radius minimal: POSIX keeps the exact
asyncio.run(_serve()) it had (its default loop is already a SelectorEventLoop /
uvloop, which is what uvicorn serves on). Only on Windows do we mirror
uvicorn.Server.run and run on the loop factory uvicorn picks, with a fallback
to WindowsSelectorEventLoopPolicy for uvicorn < 0.36.

Fixes hermes dashboard and hermes desktop (the Electron app spawns a
hermes dashboard backend). The gateway symptom in the report has a separate
root cause (no uvicorn) and is not addressed here.

Subject: [PATCH 048/244] fix(profiles): clone auth.json so OAuth credentials
 carry to cloned profiles (#51719)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Selective --clone / --clone-from / --clone-config copied .env but not
auth.json, silently dropping the credential pool — including OAuth tokens
(Anthropic `claude /login`, Codex, xAI) that never land in .env. A profile
cloned from an OAuth-authenticated default therefore resolved a different
provider (or none) than the source under provider: auto. --clone-all already
carried auth.json via the full copytree; only the selective path missed it.

Add auth.json to _CLONE_CONFIG_FILES and tighten it to 0o600 after copy,
matching .env semantics.

Subject: [PATCH 049/244] fix(desktop): guard composer mutations when the
 composer core isn't bound (#51728)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The desktop composer threw an uncaught "Composer is not available" at
startup and the input went unresponsive (#49903). assistant-ui's composer
mutators (setText/send/…) throw when the thread's composer core isn't bound
yet; the read path is null-safe but the writes are not. ChatBar pushes draft
text via aui.composer().setText() from mount-time effects (draft restore,
clearDraft, external inserts), and the v0.17.0 popout refactor (#49488)
widened the unbound window by moving the composer out of the contain wrapper
into a sibling of the thread — so the throw surfaced as an uncaught error
that wedged the input.

Wrap every composer mutation in a setComposerText helper that swallows the
unbound-core throw. The contentEditable DOM + draftRef already hold the text
and the draft-editor sync re-applies it once the core attaches, so the draft
is never lost — only the premature state push is skipped.

Subject: [PATCH 050/244] feat(gateway): configure Telegram command menu
 priority

Adds a configurable Telegram BotCommand menu cap and priority list via
platforms.telegram.extra.command_menu (max_commands clamped 1..100;
priority_mode prepend|append|replace). Default cap stays 30; hidden
commands remain invokable when typed and /commands lists the full set.

Salvaged from PR #42021. Cherry-picked onto current main; the original
edited gateway/platforms/telegram.py, now relocated to
plugins/platforms/telegram/adapter.py.

+### Command menu priority and cap (Optional)
+
+Hermes registers its command menu automatically when the Telegram gateway starts. The menu is built from the central slash-command registry plus eligible plugin/skill commands, then capped to a safe default of 30 commands so Telegram accepts the payload reliably.
+
+If you have local or plugin commands that should stay visible in Telegram's `/` picker, prioritize them in `~/.hermes/config.yaml`:
+
+```yaml
+platforms:
+  telegram:
+    extra:
+      command_menu:
+        max_commands: 30
+        priority_mode: prepend  # prepend | append | replace
+        priority:
+          - my_plugin_command
+```
+
+`priority_mode` controls how your list combines with Hermes' built-in priority list:
+
+- `prepend`: put your commands first, then Hermes defaults
+- `append`: keep Hermes defaults first, then your commands
+- `replace`: use only your list for priority ordering
+
+Telegram allows up to 100 BotCommands, but large command payloads can fail. Hermes defaults to 30 for reliability and clamps configured values to `1..100`; use `/commands` for the full command list.
+
 ## Step 3: Privacy Mode (Critical for Groups)
 
 Telegram bots have a **privacy mode** that is **enabled by default**. This is the single most common source of confusion when using bots in groups.

Subject: [PATCH 051/244] fix(telegram): raise default command-menu cap to 60
 so skills stay visible
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The 30-slot default could not fit Hermes's ~50 built-in commands, so
every skill command (and 20 built-ins) were silently dropped from the
Telegram \`/\` menu by default — they only worked when typed manually.
Raising the default to 60 keeps all built-ins plus common skill commands
visible out of the box while staying under Telegram's ~4KB payload limit.
Users can still tune it via platforms.telegram.extra.command_menu.

Subject: [PATCH 056/244] test(agent): cover interrupt tool-tail alternation
 close (#48879)

Regression coverage for the synthetic-assistant close: interrupt after a
successful tool must persist an assistant tail (placeholder when no
delivered text), real delivered text is preserved, and non-interrupted
or non-tool tails are left untouched.

+"""Regression test for #48879.
+
+When a turn is interrupted via ``/stop`` right after a tool completes — but
+before the assistant streams any final text — the transcript tail is a raw
+``tool`` message. Persisting that tail unmodified means the next user message
+lands as ``... tool → user``, a role-alternation violation that strict
+providers (Gemini, Claude) react to by hallucinating a continuation of the
+user's message before transitioning into the assistant persona.
+
+``finalize_turn`` closes the tool-call sequence on interrupt by appending a
+synthetic ``assistant`` message before persistence. ``final_response`` is
+typically empty on an interrupt, so the placeholder text is used rather than
+an empty-content assistant turn.

Subject: [PATCH 057/244] fix(discord): check pairing store for component
 button auth

Component button interactions (approve/deny, slash confirm, model
picker, clarify) were not checking the pairing store for authorization.
Users approved via `hermes pairing approve` could send messages and use
slash commands (which go through the gateway authz_mixin), but button
clicks were rejected because `_component_check_auth` only checked
env-var allowlists (DISCORD_ALLOWED_USERS, GATEWAY_ALLOW_ALL_USERS,
etc.) and not the pairing store.

This was a regression from commit f6f363662 which intentionally made
component auth fail-closed when no allowlist is set (security fix for
GHSA-mc26-p6fw-7pp6), but did not account for pairing-based auth.

Fix: add a `PairingStore.is_approved("discord", uid)` check to
`_component_check_auth`, mirroring `authz_mixin._check_authorization`.
The pairing store check runs after all allowlist checks, preserving the
fail-closed behavior for non-paired, non-allowed users.

Fixes #50627

Subject: [PATCH 058/244] docs(sessions): clarify sessions.json is the gateway
 routing index, not the session list (#51726)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Users who inspect ~/.hermes/sessions/sessions.json see only gateway entries
(e.g. agent:main:whatsapp:dm:...) and mistake it for the session index that
hermes sessions list / /sessions read — which is actually state.db. Issue
#49361 reported CLI sessions as 'invisible' on this premise.

- gateway/session.py: write a self-documenting _README sentinel at the top of
  sessions.json explaining it's the gateway routing index and that ALL sessions
  (CLI/TUI/gateway) live in state.db; skip _-prefixed keys on load so the
  sentinel never round-trips into a SessionEntry.
- Harden every sessions.json reader against the sentinel: mcp_serve loader,
  gateway/mirror.py, gateway/channel_directory.py all skip _-prefixed keys.
- docs/user-guide/sessions.md: warning callout naming the exact symptom.
- tests: assert prune ignores metadata sentinels; add round-trip coverage.

Subject: [PATCH 059/244] fix(matrix): use member_count as DM signal for named
 DM rooms

Most Matrix clients auto-set a room name when creating a DM (e.g.
"Alice & Bot" from participant display names), so the old
`is_direct and not has_explicit_name` heuristic classified virtually
all client-created DM rooms as "room", forcing require_mention gating
in legitimate one-on-one DMs.

member_count is now the primary DM signal: <=2 members means the room
is necessarily a 1:1 conversation, regardless of m.direct or an explicit
name. A room that grew to 3+ members but is still in stale m.direct is
still classified as a room (conflict flag set). Falls back to the
m.direct + name heuristic when the count is unavailable.

Also hardens _get_room_member_count with a joined_members API fallback
when the cache-backed state_store is empty.

Salvaged from #48554 by @justemu onto the current plugin adapter path
(gateway/platforms/matrix.py -> plugins/platforms/matrix/adapter.py).

Fixes #48551

Subject: [PATCH 061/244] fix(anthropic): use platform.claude.com for OAuth
 token exchange

Anthropic migrated the OAuth token endpoint from
console.anthropic.com/v1/oauth/token (now returns HTTP 404) to
platform.claude.com/v1/oauth/token. The token *refresh* path already
iterated both hosts, but the two initial code-exchange call sites were
hardcoded to the dead console host, so every new Claude OAuth login
failed with 'Token exchange failed: HTTP Error 404: Not Found' and saved
no credentials.

Fix the whole bug class:
- Add _OAUTH_TOKEN_URLS [platform.claude.com, console.anthropic.com] in
  agent/anthropic_adapter.py; _OAUTH_TOKEN_URL now points at the live
  host for backward-compat with existing imports.
- run_hermes_oauth_login_pure() (CLI flow) iterates the list, first
  success wins, mirroring the refresh path.
- hermes_cli/web_server.py (desktop dashboard flow) imports the list and
  iterates it too, so the GUI login path is fixed identically.

Probe: console.anthropic.com/v1/oauth/token -> HTTP 404 (gone),
platform.claude.com/v1/oauth/token -> HTTP 400 (alive). Verified a real
Claude MAX OAuth login now succeeds end-to-end.

Subject: [PATCH 062/244] test(anthropic-oauth): cover login token-endpoint
 host + fallback

Add two regression tests for the salvaged #48706 fix:
- login token exchange targets platform.claude.com first
- falls back to console.anthropic.com when the new host is unreachable

Also map the salvaged contributor's noreply email in release.py

Subject: [PATCH 063/244] refactor(dashboard): remove the dead tools box from
 the chat sidebar (#51737)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The dashboard chat sidebar's tool-call activity card was disabled in the
product — both ChatPage mounts passed showTools={false} (since #49077),
so the box never rendered. The sidebar still subscribed to tool.* events
and accumulated them in state for a panel nobody saw.

Remove the tools card, the showTools prop, the tool.* event handling and
state, and the now-orphaned ToolCall component. The /api/events
subscription stays for session.info (live title) and
dashboard.new_session_requested. The sidebar is now just the model
selector box; the session list (ChatSessionList) is unchanged.

No behavior change in the live dashboard — the tools box was already
hidden.

Subject: [PATCH 065/244] fix(gateway): detect launchd in /restart
 service-manager probe (#43475)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On a launchd-managed gateway (macOS), /restart stopped the gateway but
never relaunched it: the handler's service detection checks only
INVOCATION_ID (systemd) and container markers, so under launchd it takes
the detached path and exits 0 — which KeepAlive.SuccessfulExit=false
treats as a deliberate stop. The gateway stays silently dead until a
manual launchctl kickstart.

Detect launchd via XPC_SERVICE_NAME, which launchd sets to the job label
for processes it spawns. The probe deliberately excludes the literal
"0": interactive macOS shells inherit XPC_SERVICE_NAME=0 (a truthy
string), and routing an unsupervised interactive gateway to the service
path would make it exit non-zero with nothing to revive it.

Routing through via_service=True (rather than forcing a non-zero exit
on the detached path) matters: the detached path also spawns a helper
that relaunches the gateway, so exiting non-zero there would have BOTH
the helper and launchd respawn it — two gateways racing for the same
bot tokens. The service path spawns no helper; launchd is the single
respawner.

Fixes #43475. Supersedes the run.py-era probes in #19940/#33393 (the
handler has since moved to gateway/slash_commands.py) and avoids the
double-spawn risk in the exit-code-site approaches (#43498, #43596).

Subject: [PATCH 067/244] docs: stop recommending pip install; curl installer
 is the only supported path (#51743)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* docs: stop recommending pip install hermes-agent; point to install script

The install script is the only supported install path (it provisions a
managed, isolated uv environment). Replace bare `pip install hermes-agent`
primary-install recommendations with the curl install script, and rewrite
optional-extra snippets (`pip install "hermes-agent[X]"`) to the managed-env
form `cd ~/.hermes/hermes-agent && uv pip install -e ".[X]"` that matches the
installer and the English quickstart.

Covers English docs + zh-Hans mirrors, the achievements plugin README, and
realigns the zh-Hans quickstart to the English Desktop-installer-first layout
(dropping its stale "Method A — pip (simplest)" section).

* docs: drop pip as a supported install/update method

Removes the 'pip installs' supported-method sections from updating.md and
cli-commands.md (EN + zh-Hans): the curl install script is the only supported
way to install/update the Hermes CLI. The _cmd_update_pip pip/pipx branches
remain in code as an undocumented safety net for users who already have such an
install, but the docs no longer advertise pip as a path.

Also normalizes a bare `pip install -e '.[acp]'` to the managed-env form.

Leaves python-library.md untouched: importing AIAgent as a library dependency
into your own project is a distinct use case where pip is correct.

Subject: [PATCH 068/244] fix(browser): validate agent-browser is runnable, not
 just present (#51740)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After `hermes update`, a globally-installed agent-browser's npm postinstall
(fixUnixSymlink) re-points the global symlink (e.g. /opt/homebrew/bin/agent-browser)
at our local node_modules binary. The next update wipes node_modules, leaving a
dangling symlink that `which` still reports but exec fails on with exit 127 —
silently breaking every browser tool (#48521).

Root cause is trust-on-presence: shutil.which/Path.exists accept a name that
resolves but won't run. Add hermes_constants.agent_browser_runnable() (resolves
the path + runs --version) and gate all four resolution sites on it:
_find_agent_browser now skips a dead candidate and falls through to the next
working one (extended PATH -> local .bin -> npx), self-healing the dangling link.
dep_ensure/doctor/nous_subscription validate too; doctor warns on a broken link.

Closes #48521.

Phase 7 Unit 7d-B. When an operator opts an instance OUT of the Team Gateway
relay (Unit 7b deprovision), the connector revokes the per-gateway secret and
closes the gateway's WS with 4401. The reconnect supervisor previously treated
EVERY close as retryable, so the live process spun "retrying 4401" forever and
the dashboard showed a red error — opt-out looked like a failure.

Now a 4401 close that arrives AFTER a successful handshake is recognized as a
terminal credential revocation:

- ws_transport.py: track `_handshake_succeeded` (set when a descriptor is
  received); on a 4401 close after a prior success, latch `auth_revoked` and do
  NOT spawn the reconnect supervisor. A 4401 BEFORE any successful handshake
  stays retryable (cold-start / not-yet-provisioned race, not a revocation).
  New `auth_revoked` property + a websockets-version-safe close-code reader
  (prefers `.rcvd`/`.sent` Close frames; `.code` is deprecated in websockets 13+).
- adapter.py: a revocation monitor turns `transport.auth_revoked` into a clean,
  NON-retryable `relay_disabled` fatal and notifies the gateway's fatal-error
  handler (so the adapter is removed and NOT queued for reconnection — the
  credential is dead until the instance is recreated). Monitor is cancelled on
  disconnect; only started when the transport exposes `auth_revoked` (prod WS).
- run.py: `_handle_adapter_fatal_error` maps the `relay_disabled` code to a
  `disabled` platform_state (not `fatal`/`retrying`).
- web: PlatformsCard renders the `disabled` state with a neutral outline badge,
  a PowerOff icon, and muted (not destructive-red) text + message. New optional
  `status.disabled` i18n string ("Disabled").

Also bundles the Phase 7 contract-doc update (this doc is authoritative in
hermes-agent): docs/relay-connector-contract.md gains an "Author-first
resolution + the account-link (DM) path" section documenting the
multi-tenant-guild rule (D-7.2 — route by authenticated author binding, never by
guild; unlinked → fail-closed), the `/link <code>` DM flow, and the
connector-authoritative opt-out + terminal-4401 behavior this PR implements.

Tests: +2 ws_transport (4401-after-handshake terminal / no-reconnect;
4401-before-handshake stays retryable) and +2 adapter (revocation → non-retryable
relay_disabled fatal + handler fired; no-revocation → no fatal). 138 relay tests
pass (incl. the contract-doc conformance test); ruff clean; web tsc clean.

Phase 7 Unit 7d-B (relay-adapter solo lane). Q17 → Option 2; Option 3 (live
de-register, no recreate) + the restart-re-provision hole deferred post-alpha.

 token/socket/process delivered it. This keeps one shared bot able to front many
 tenants (Phase 6) without overloading an existing field.
 
+### Author-first resolution + the account-link (DM) path (Phase 7)
+
+Phase 7 adds **self-serve, per-user onboarding to a shared bot**, which changes
+*which* discriminator resolves the instance for a routed inbound message — and
+adds a management path for users to bind their own account.
+
+**Author-first resolution (the multi-tenant-guild rule, D-7.2).** A single
+Discord guild may hold **many** tenants — different members each linked to their
+own agent. So for delivery the connector resolves the destination instance from
+the **authenticated author binding** (`user_instance_binding`, keyed by
+`(tenant, platform, platform_user_id)` via `resolveByUser`), **NOT** by a
+guild→instance route. Concretely:
+
+- A routed message authored by a **linked** user reaches **only that user's**
+  instance — even when a second linked user in the **same guild** is served by a
+  different instance (each reaches only their own).
+- A message authored by an **unlinked** user resolves to **no** instance and is
+  dropped (**fail-closed** — never broadcast to the guild's other tenants).
+- The author id used is the **authentic `user_id` off the observed event**, the
+  same `SessionSource.user_id` documented above — never a value asserted by a
+  gateway or carried in a management frame.
+
+This is the per-`user_id` owner-only routing the connector enforces in
+`WsGatewayDelivery` (the gateway-side multi-tenant-guild E2E driver
+`gateway_multitenant_guild_driver.py` is the cross-repo oracle).
+
+**The account-link (DM) path.** A user binds their account to an instance with a
+one-time code, redeemed by DMing the shared bot:
+
+1. The owner triggers a link from the Portal (or a self-hosted CLI). The
+   connector mints a short-lived **link code** for the **authenticated**
+   instance (`POST /manage/link`; instanceId comes from the caller's principal —
+   a NAS-signed `aud=agent:{instanceId}` token or the instance's own per-gateway
+   secret — **never** the request body).
+2. The user sends `/link <code>` as a **direct message** to the shared bot from
+   the account they want to bind.
+3. The connector's inbound observer **consumes** that DM (it is not routed to any
+   agent) and writes the `user_instance_binding` using the **authentic
+   `user_id`** off the observed DM event. From then on, author-first resolution
+   routes that user's messages to the bound instance.
+
+**Opt-out is connector-authoritative.** Deprovisioning an instance
+(`POST /manage/deprovision`) drops its author bindings (so its users stop
+resolving to it) **and** revokes its per-gateway secret (so its socket can no
+longer authenticate — the next WS upgrade is closed **4401**). A gateway that
+sees a **4401 close after a previously-successful handshake** treats it as a
+terminal revocation: it stops reconnecting and reports the relay platform as
+**disabled** (not a retryable error). A 4401 *before* any successful handshake
+stays retryable (a cold-start / not-yet-provisioned race, not a revocation).

Subject: [PATCH 070/244] docs(chronos): pin hop-1 auth to the hosted-agent
 bootstrap token
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The wire contract said hop 1 uses "the agent's existing Nous Portal
access token" but didn't name WHICH of an agent's two identities that is.
A hosted agent never holds an `agent:{instanceId}` OAuth client (that
shape is minted only by the interactive dashboard auth-code grant); its
own outbound portal calls use the bootstrap-session token (client
`hermes-cli-vps`) planted in auth.json on first boot. NAS must resolve
the instance id from either an `agent:{id}` client OR the bootstrap
session (AgentInstance.bootstrapSessionId), not gate on `agent:*` alone —
which 403'd every real hosted-agent provision in prod.

Documents the NAS-side fix (resolveAgentCronInstanceId) so the contract
and the implementation agree.

Subject: [PATCH 071/244] fix(cli): honor non-interactive context in
 prompt_yes_no

The dashboard/desktop spawn gateway actions with stdin=DEVNULL and
HERMES_NONINTERACTIVE=1 (hermes_cli/web_server.py), but prompt_yes_no
ignored that contract and called sys.exit(1) on the resulting EOFError.

On Windows, `gateway start` asks "Install it now so the gateway starts on
login? [Y/n]" when the scheduled task / startup entry is not yet
installed. Spawned from the desktop app there is no stdin to answer it, so
every desktop-triggered gateway restart aborted at that prompt and the
gateway never started ("Gateway service is not installed").

Fall back to the prompt's default when HERMES_NONINTERACTIVE is set, and
treat a bare EOFError as "accept default" rather than exiting. This lets
the Windows start path proceed unattended (Startup-folder fallback + direct
spawn) while interactive TTY usage is unchanged. Ctrl+C still exits.

 fallback runtime probe

When shouldPreserveConfiguredOnFallback keeps configured=true, also call
notifyError('runtime-not-ready', ...) so the user knows the backend wasn't
verified instead of silently proceeding. Adapted from @mohamedorigami-jpg's
approach in PR #37634.

Subject: [PATCH 076/244] fix(desktop): use notify() with stable id for
 fallback notification
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

hermes-pr-review findings:
- notifyError('runtime-not-ready', msg) misused the (error, fallback) API:
  the key became the notification body and the message became the title.
  Switch to notify({ id, kind, title, message }) which puts content in the
  right slots.
- The stable id 'runtime-not-ready' deduplicates: notify() replaces by id,
  so repeated refreshOnboarding calls during an outage no longer stack
  up to 4 persistent error toasts.
- Remove dead !state.manual guard from shouldPreserveConfiguredOnFallback:
  refreshOnboarding already short-circuits on manual before the helper.
- Test: seed localStorage with '1' before asserting it survives (was testing
  the wrong invariant — null in, null out).
- Test: use static import for spy instead of fragile await import.
- Test: add negative case for requested=true + configured=true (should
  still downgrade — requested overrides preservation).

Subject: [PATCH 077/244] fix(compression): abort (preserve context) on
 transient network summary failure (#29559, #25585)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When context compaction's summary generation fails, the compressor's default
path (abort_on_summary_failure=False) drops the middle window and inserts a
static 'summary unavailable' marker — destroying the compacted turns. #29559
reported the field impact: a Connection error at the compaction moment dropped
124->15 messages (110 lost) for a long browser-automation task; #25585 is the
same failure mode (failed summary commits a destructive compaction anyway).

compress() already has an EXCEPTION to the historical drop default: auth
failures (401/403) ALWAYS abort and preserve the session, because rotating into
a placeholder-summary child on a broken credential strands the user. A transient
network/connection error is the same situation in reverse: it WILL recover, and
retrying then is strictly better than discarding context for a momentary blip.

Extend the always-abort carve-out to terminal connection/network failures:
- new _last_summary_network_failure flag, set in _generate_summary's terminal
  failure branch when _is_connection_error(e) (reached only after any main-model
  fallback is exhausted), reset alongside the auth flag;
- compress() aborts when it's set (returns messages unchanged,
  _last_compress_aborted=True), independent of abort_on_summary_failure;
- a network-specific operator warning (distinct from the auth + config-flag
  messages).

Scoped to connection errors only: a generic 500/400 still takes the historical
fallback-drop path (test_non_auth_failure_still_uses_fallback_path stays green).

Tests: network-failure detection + abort-despite-flag-false, both mutation-checked
(removing the flag-set fails detection; removing the carve-out fails the abort).

Subject: [PATCH 078/244] fix(gateway): offload handoff watcher SessionDB
 polling off the event loop

The Discord gateway heartbeat stalled ('Shard ID None heartbeat blocked
for more than N seconds') because _handoff_watcher polled the synchronous,
blocking SQLite-backed SessionDB directly on the asyncio event loop every
2s. Each list_pending/claim/complete/fail call performed blocking disk I/O
on the loop thread, starving the Discord heartbeat coroutine.

Wrap every blocking SessionDB call inside the watcher loop in
asyncio.to_thread(...) so the SQLite work runs on a worker thread and the
event loop (and heartbeat) stays responsive. These four call sites are the
only synchronous self._session_db.* calls inside the watcher loop body.

Adds tests/gateway/test_handoff_watcher_async_db.py asserting the watcher
offloads its SessionDB calls via asyncio.to_thread (mutation-survivable:
reverting any to_thread wrap fails the corresponding assertion).

Fixes #40695

Subject: [PATCH 079/244] fix(gateway): offload /model provider-listing off the
 event loop (#41289)

The Discord/Telegram /model slash command listed providers synchronously
on the gateway's async event loop. list_picker_providers /
list_authenticated_providers are blocking and can fall through to a
synchronous urllib HTTP fetch when the on-disk provider cache is stale,
freezing the loop for 120-150s -> "application did not respond" and
delayed agent starts.

Port #41304's asyncio.to_thread offload to the current handler location.
The handler moved from gateway/run.py to gateway/slash_commands.py
(_handle_model_command); wrap BOTH blocking call sites so the whole bug
class is covered:

  - picker path        -> list_picker_providers
  - text-fallback path -> list_authenticated_providers

asyncio.to_thread is already idiomatic in this module (and asyncio is
imported), so the loop now stays responsive while the (possibly
network-bound) listing runs on a worker thread.

Adds tests/gateway/test_model_command_async_offload.py asserting the
offload contract at the real handler seam for both paths (mutation-
survivable: reverting either to_thread wrap fails the matching test).

+"""Regression tests for #41289: the Discord/Telegram ``/model`` slash command
+must not run the blocking provider-listing on the gateway's async event loop.
+
+``list_picker_providers`` / ``list_authenticated_providers`` are synchronous and
+can fall through to a blocking ``urllib`` HTTP fetch when the on-disk provider
+cache is stale. Running that directly on the event loop froze the gateway for
+120-150s ("application did not respond" + delayed agent starts).
+
+Fix (ported from #41304, which patched the old ``gateway/run.py`` location):
+``_handle_model_command`` offloads BOTH provider-listing calls via
+``asyncio.to_thread`` so the loop stays responsive:
+
+  * line ~1161 — picker path     -> ``list_picker_providers``
+  * line ~1382 — text-fallback   -> ``list_authenticated_providers``
+
+These tests assert the *offload contract* at the real handler seam: each listing
+function must be dispatched through ``asyncio.to_thread`` and must NOT be invoked
+directly. Reverting either ``to_thread`` wrap (calling the sync fn inline again)
+makes the corresponding test fail — i.e. the tests are mutation-survivable.

Subject: [PATCH 080/244] feat(openviking): add full recall prefetch policy
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Salvage of PR #48927 by @ehz0ah, which consolidates OpenViking recall
work from #41706 (@huangxun375-stack), #33260, #49975, and #32444.

Replaces stale background post-turn prefetch warming with synchronous
current-query recall. The old queue_prefetch warmed the PREVIOUS user
message while turn-start recall consumed the CURRENT one, so injected
context was always about the wrong topic.

Changes:
- prefetch() now does session-aware /api/v1/search/search with the
  current query, falls back to /api/v1/search/find on failure
- Contract-safe payloads: limit, score_threshold, context_type,
  session_id — no top_k, no search-body mode, no target_uri
- L2 content reads for items with level=2 or empty abstracts, capped
  at full_read_limit (default 2)
- Local ranking (score + query-token overlap + leaf boost), dedup,
  score threshold, and injected-char budget
- queue_prefetch() is now a no-op (background warming removed)
- Additive batched viking_read: uris param accepts up to 3 URIs
- Per-request timeout support on _VikingClient.get/post/delete
- Removes stale _prefetch_result/_prefetch_thread/_prefetch_generation
  state and _invalidate_prefetch_state()
- Strengthened system_prompt_block guidance

Salvage follow-up fixes:
- Expose all 8 recall config knobs in get_config_schema() (PR #48927
  had removed them; #41706 correctly exposed them). Env vars remain
  as internal mechanism but are now visible in setup wizard.
- Lower default timeout 8s→4s, request_timeout 6s→3s, full_read_limit
  3→2 to reduce per-turn blocking latency.

Subject: [PATCH 081/244] fix(gateway): consume was_auto_reset so /model
 survives session auto-reset
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When `/model X` is the FIRST message after an idle/daily/suspended auto-reset,
the slash-command path stores a session model override but leaves
`session_entry.was_auto_reset = True` (it never passes through
`_handle_message_with_agent`, which is where the flag was consumed). On the
NEXT regular message, the auto-reset cleanup block pops the freshly-stored
model/reasoning override BEFORE the flag is consumed — so the switch is
silently lost and resolution falls back to the config default, while the
session DB still shows the switched model (a two-sources-of-truth divergence).

Consume the flag at both sites:
  1. gateway/run.py — capture `was_auto_reset` into a local and set the
     attribute False immediately at the top of the cleanup block, so the
     cleanup can't re-fire on a later message and wipe an override stored
     between turns. Downstream reads use the captured local.
  2. gateway/slash_commands.py — the model path consumes the flag before
     storing the override, so a /model-first-after-auto-reset isn't wiped by
     the next message's cleanup.

Salvaged from #48062 by x7peeps (authorship preserved).

Tests: tests/gateway/test_48031_model_switch_after_auto_reset.py — AST
invariants pinning both consume sites (load-bearing; verified they fail when
either consume is removed). Mirrors the AST-pin approach in
test_35809_auto_reset_clean_context.py. Gateway session/reset suite: 16 passed.

Fixes #48031

+"""Regression test for #48031 — /model switch lost after session auto-reset.
+
+When `/model X` is the FIRST message after an idle/daily/suspended auto-reset,
+it stores a session model override but the `was_auto_reset` flag is left True
+(the slash-command path doesn't pass through the message handler that consumes
+it). On the NEXT regular message, the auto-reset cleanup block in
+`_handle_message_with_agent` pops the freshly-stored override BEFORE the flag
+is consumed, so the switch is silently lost and resolution falls back to the
+config default — while the session DB still shows the switched model (a
+two-sources-of-truth divergence).
+
+The fix consumes `was_auto_reset` at two sites:
+  1. the cleanup block in gateway/run.py captures it into a local and sets the
+     attribute False immediately (so it can't re-fire next message);
+  2. the slash-command model path in gateway/slash_commands.py consumes it
+     before storing the override (so a /model-first-after-reset isn't wiped).
+
+These are AST invariants — load-bearing pins that fail if either consume is
+removed (mirrors test_35809_auto_reset_clean_context.py's approach).

Subject: [PATCH 082/244] fix(models): gate openai-codex/xai-oauth soft-accept
 to family-shaped slugs (#45006)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Completes the #45006 fix. PR-base commit (configured-provider routing) handles
the case where a typed model IS declared in user/custom provider config. This
commit closes the other root: when a typed model is NOT in any config and the
current provider is a soft-accepting one (openai-codex / xai-oauth), the
hidden-model soft-accept (#16172 / #19729) would accept ANY unknown name as a
hidden model — so `qwen3.5-4b` typed on a Codex-default session "succeeded" and
mislabeled the provider as "OpenAI Codex" (the exact reported symptom), then
400'd on the next turn.

Gate the soft-accept to slugs that plausibly belong to the provider's family
(openai-codex -> gpt-/codex-/o1/o3/o4; xai-oauth -> grok-). Family-shaped
unknown slugs are still soft-accepted (preserving the #16172 entitlement-gated
hidden-model intent); unrelated names are rejected with actionable guidance to
pin the right provider via `--provider <slug>` or the picker.

Adds TestCodexSoftAcceptPlausibilityGate (5 tests): unrelated names rejected on
codex/xai, family-shaped hidden slugs still accepted, real catalog models
unaffected. Verified load-bearing.

Subject: [PATCH 083/244] fix(tui): targeted save_config_value for model
 persistence (#48305)

The TUI model-switch persistence (_persist_model_switch) rewrote the entire
model config block via save_config(), destroying sibling keys the user set
under model: (model_slots, model_fallback, base_url, ...) on every switch.

Use targeted, atomic, comment-preserving save_config_value("model.default" /
"model.provider" / "model.base_url") writes instead, so a model switch only
touches the keys it changes.

Subject: [PATCH 084/244] fix(model-switch): prevent custom-provider
 misattribution in model picker (#48305)

When the current provider is a custom endpoint (custom or custom:*), the model
switch pipeline must NOT auto-switch to a native provider/OpenRouter based on a
static-catalog match. The user explicitly configured their own endpoint and the
same model name may be served there; silently rewriting model.provider destroys
their config.

- detect_static_provider_for_model(): skip the static-catalog scan when the
  current provider is custom/custom:*
- switch_model() Step e: extend is_custom to cover custom:* so the
  detect_provider_for_model() last-resort fallback cannot fire

 apps/desktop 0.17.0

The apps/desktop workspace was bumped to 0.17.0 in apps/desktop/package.json
but package-lock.json still recorded 0.15.1, so npm install reports the lock
as out of date and rewrites it on every fresh install. Regenerate the lock
(npm install --package-lock-only) to record the current 0.17.0; one-line
change, no dependency resolution churn.

Subject: [PATCH 090/244] fix(install): kill gateway running from venv before
 recreating it (Windows)

The Windows venv-recreate guard only runs `taskkill /IM hermes.exe`, but the
gateway that a scheduled task or watchdog autostarts runs as
`pythonw.exe -m hermes_cli.main gateway run` straight out of venv\Scripts\.
Its image name is python/pythonw, so taskkill never matches it; it keeps the
venv's native extensions (e.g. tornado\speedups.pyd) loaded, and the following
Remove-Item fails with "Access to the path is denied" -- aborting boot at the
venv stage so the desktop app never loads.

Additionally stop any process whose executable lives under this venv, matched
by path so the image name is irrelevant and a global/system python outside the
venv is never touched.

Subject: [PATCH 091/244] fix(install): harden venv-resident process sweep on
 Windows
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow-up to the salvaged venv-recreate fix. Three changes to the
Install-Venv pre-delete sweep:

- Match the venv path with a case-insensitive StartsWith instead of the
  PowerShell -like operator. A venv path containing wildcard
  metacharacters ('[', ']') — legal in a Windows user name — silently
  fails to match under -like, which would let the locking process slip
  through and reintroduce the exact access-denied failure this fix
  closes.
- Retry Remove-Item once after a short pause. A force-killed process can
  take a moment to release its file handles, so the first delete may
  still hit a locked .pyd; retry before failing the stage.
- Note in a comment that the gateway autostart task runs at LIMITED
  integrity as the current user, so the installer always runs at
  equal-or-higher integrity and can read the process executable path,
  and that Get-CimInstance is preferred over Get-Process because it
  returns a null path for an uninspectable process instead of throwing.

Adds a regression test asserting the recreate branch sweeps by venv path
prefix, uses StartsWith rather than -like, and runs the sweep before
Remove-Item.

Covers issues #47036, #47557, #47910.

Subject: [PATCH 092/244] fix(gateway): surface retry hint instead of silently
 dropping turn after /stop (#31884)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After /stop, the next user message can hit a stale generation token and
return with api_calls=0, no failure, no interruption. _normalize_empty_agent_response
fell through to an empty string, so the gateway logged "response=0 chars"
and sent nothing — the message was silently lost while internal work
sometimes continued.

Add the api_calls==0 / not-failed / not-interrupted / not-partial branch
to the single normalization chokepoint so the user gets a short retry hint
instead of silence. Regression test asserts the hint surfaces.

Salvaged from #33851 (re-applied on current main; original was 1401 commits
behind and the function had moved).

Subject: [PATCH 093/244] feat(desktop): remember window
 size/position/maximized across launches (salvage #39154)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The desktop window opened at a hardcoded 1220×800 every launch, discarding
whatever size and position the user left it at (#39101) — on macOS the dock
reopen was the most visible case, but every restart reset it.

A small window-state.json under userData (same pattern as connection.json /
updates.json) records the window's normal bounds plus its maximized flag,
written debounced on resize/move/maximize and flushed on close, applied on the
next createWindow(). getNormalBounds() captures the pre-maximize size so an
un-maximize next session lands where the user actually sized it.

Restore is defensive: sanitize rejects garbage, drops off-screen positions
(window falls back to Electron centering), and caps a size saved on a
since-disconnected larger monitor to the largest current display. The geometry
math lives in a side-effect-free window-state.cjs so it unit-tests with
node --test, no Electron boot. No new dependency.

Salvages #39154 by @jeffrobodie-glitch — same userData approach and validation
intent, reimplemented tighter and folded into one module.

Subject: [PATCH 094/244] =?UTF-8?q?feat(pets):=20prompt=20=E2=86=92=20atla?=
 =?UTF-8?q?s=20sprite-generation=20engine?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Turn a text prompt into a petdex-spec spritesheet (8×9 grid of 192×208
cells), grounded so every animation row stays the same creature:

- orchestrate: base drafts (distinct variation nudges) → per-row grounded
  generation → atlas compose; one image call per row, rows fan out in parallel.
- atlas: frame-perfect registration in normalize_cells — 1-D cross-correlation
  of each frame's column-mass profile locks the body (robust to limbs/cape),
  one shared per-state scale, bottom-anchored; plus alpha-hole repair, gutter
  severing, and interior-seeded chroma-pocket clearing.
- prompts: pixel-art-by-default style hints + registration constraints.
- store: local pet write (register_local_pet), slugify/unique_slug,
  export_pet, slug-realigning rename_pet, createdBy provenance.

+"""Deterministic spritesheet assembly — generated row strips → Hermes atlas.
+
+Image-generation models are good at *drawing* a row of poses but bad at exact
+grid geometry, so the model never owns the atlas layout: it produces one loose
+horizontal strip per state, and these deterministic ops slice that strip into
+clean, centered, transparent ``192x208`` cells and pack them into the sheet our
+renderer reads.
+
+The atlas follows the **petdex/Codex standard**: 8 columns x 9 rows of
+``192x208`` cells (``1536x1872``), with the row order + per-row frame counts
+from OpenAI's ``hatch-pet`` skill. Our renderer (:mod:`agent.pet.render`) keys
+frames as ``rows = states, cols = frames`` via
+:data:`agent.pet.constants.CODEX_STATE_ROWS`, and a pet built here is a valid
+``petdex submit`` spritesheet. Rows shorter than 8 columns leave the trailing
+cells fully transparent.
+
+Note ``running`` is the *working* state (in-place processing), NOT locomotion —
+``running-right`` / ``running-left`` are the actual directional walk cycles.
+
+The frame-segmentation, fit-to-cell, and transparency-residue logic is adapted
+from OpenAI's ``hatch-pet`` skill (openai/skills, Apache-2.0).

Subject: [PATCH 095/244] feat(pets): OpenRouter + Nous Portal image backend
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reference-grounded image provider over the OpenRouter-compatible
chat-completions image protocol (Gemini Flash Image et al.). Nous Portal
proxies OpenRouter, so one provider serves both — giving pet generation a
reference-capable backend beyond OpenAI gpt-image.

+"""OpenRouter-compatible image generation backend (OpenRouter + Nous Portal).
+
+Both OpenRouter and the Nous Portal inference endpoint speak the same
+OpenAI-style ``/chat/completions`` image-generation protocol: send
+``modalities: ["image", "text"]`` with an image-output model (e.g.
+``google/gemini-2.5-flash-image``), pass reference images as ``image_url``
+content parts for grounding, and read the generated images back from
+``choices[0].message.images[].image_url.url`` (a ``data:image/...;base64`` URI).
+
+Nous Portal proxies OpenRouter, so one implementation services both — we only
+swap the resolved ``(base_url, api_key)``. Credentials are resolved through the
+agent's existing :func:`~hermes_cli.runtime_provider.resolve_runtime_provider`,
+which already understands OpenRouter's key pool and the Nous OAuth device-code
+token, so this plugin never reinvents auth.
+
+Reference grounding is the reason pet sprite generation cares about this
+backend: each animation row must stay the same character as the chosen base
+frame, which only works on models that accept image input. Gemini Flash Image
+("nano-banana") does, so both providers advertise image-to-image support.

Subject: [PATCH 096/244] feat(pets): generation RPCs, non-blocking gallery +
 gateway plumbing

- pet.generate / pet.hatch (parallel rows, off the reader thread) +
  cooperative pet.cancel; pet.export / pet.rename.
- pet.gallery localOnly fast path + background manifest prefetch so the
  picker never blocks on petdex; rename follows the active-pet config.
- gateway request gains optional timeout + AbortSignal for real Stop.

Dedicated generate modal (Cmd-K → Pets → Generate): prompt → 2×2 draft
grid → egg hatch → preview → adopt, width fits each phase.

- Reuses shared primitives (Button/Input/Dialog/Alert/GenerateButton);
  cards use selectableCardClass; only canvas + range stay raw.
- Animated creme pixel egg + PetStarShower hatch celebration (canvas).
- Live streamed drafts with a real Stop (AbortSignal); clean default name.
- Manage generated pets: badge + top ranking, rename (optimistic), safe
  delete (confirm + drop), export — in both the Cmd-K and Settings lists.
- pet-gallery routes every RPC through profile-scoped petRpc; i18n ×5.

+ * Feature store for the "generate a pet" flow (Cmd-K → Pets → Generate).
+ *
+ * Three backend steps, mirrored as state here:
+ *  - `pet.generate` produces N cheap base-look *drafts* keyed by a `token`.
+ *  - `pet.hatch` turns the chosen draft into a full animated pet — installed but
+ *    NOT active — and returns its renderer payload so we can preview all frames.
+ *  - the user then *adopts* (`pet.select`) or *discards* (`pet.remove`) it.
+ *
+ * The store owns the draft set, the selected variant, the hatched preview, and
+ * the busy/error status so the page is a thin view. Retry == regenerate (new
+ * token). Kept separate from `pet-gallery` because its lifecycle (ephemeral
+ * drafts + an unadopted preview) is unrelated to the long-lived gallery cache.

Subject: [PATCH 098/244] fix(gateway): offload agent cleanup off the event
 loop in /new reset (#35994)

The /new (and /reset) confirmation-button callback runs the slash-confirm
handler on the asyncio event loop (see _request_slash_confirm). That handler
calls _handle_reset_command, which invoked the SYNCHRONOUS, potentially
long-blocking _cleanup_agent_resources inline: agent.close() tears down
terminal sandboxes, browser daemons and background processes (subprocess
waits), and shutdown_memory_provider() can make a network call. A slow
teardown wedged the entire event loop, so the bot went silent and stopped
processing all messages until a manual restart.

Offload _cleanup_agent_resources via the existing contextvar-preserving
_run_in_executor_with_context helper, bounded by asyncio.wait_for with a
named _RESET_CLEANUP_TIMEOUT_S (30s). The loop is never blocked; on timeout
the reset proceeds and the worker thread is left to finish on its own (it
cannot be cancelled). The text /new path is unaffected (already off-loop).

Tests (tests/gateway/test_35994_reset_button_deadlock.py): the loop keeps
ticking while close() blocks in its worker thread; a cleanup that raises is
swallowed (warning logged) and the reset still rotates the session; a
cleanup that times out degrades gracefully. All three are mutation-verified
to fail without their respective production branch.

Subject: [PATCH 099/244] feat(pets): offer backend setup when generation is
 unavailable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When no reference-capable image backend is configured, generating a pet is
impossible — so instead of a dead prompt + post-hoc error, the overlay now
detects it up front and offers a way out:

- pet.generate.status RPC reports whether a reference-capable provider
  (OpenRouter / Nous Portal / OpenAI) is set up; the overlay probes it on
  open and swaps the prompt for a friendly setup card (paw, one-line copy,
  "Set up image generation" → /settings?tab=providers, key links).
- useRouteOverlayActive(): reusable hook so any portaled modal yields the
  screen to a full-screen route overlay (e.g. settings) and reappears —
  re-running its mount effects — on return, instead of closing. The probe
  re-runs on that remount, so adding a key flips the card to the prompt.

Subject: [PATCH 100/244] fix(memory): skip drift guard for add (append-only)
 action (#42874)

The drift guard (introduced for #26045) correctly protects replace/remove
from clobbering un-roundtrippable content, but it also fires on the add
path. Since add only appends and never overwrites, the guard is
unnecessary and causes false positives when prior add() calls in the same
session shift the byte count of the on-disk file.

Add skip_drift parameter to _reload_target() and pass True from add().
Replace/remove continue to use the drift guard unchanged.

Salvaged from #42880 by @liuhao1024.

Closes #42874

Subject: [PATCH 101/244] fix(compression): make minimum context floor
 configurable (#31600)

Add compression.minimum_context_floor config key that allows users
to lower the compression threshold floor below the hardcoded 64K
default, preventing infinite tool-call loops on models whose
structured output degrades well before 64K tokens.

- agent/model_metadata.py: add get_configurable_minimum_context()
  helper with 16K hard safety limit
- agent/context_compressor.py: accept minimum_context_floor param,
  thread it through _compute_threshold_tokens
- agent/conversation_compression.py: use compressor's floor for
  aux model context validation
- agent/agent_init.py: read compression.minimum_context_floor from
  config and pass to ContextCompressor
- gateway/run.py: cache-busting includes new key

Salvaged from #31686 by @Tranquil-Flow onto current main.
Resolves conflicts with in-place compaction (#38763) and max_tokens
threshold computation (#43547) that landed after the original PR.

Closes #31600

From aacc6bb0a8117940b2f9279b07bf9124fb7cfe09 Mon Sep 17 00:00:00 2001
From: texhy <dev@pixlmedia.no>
Date: Thu, 25 Jun 2026 01:10:13 +0530
Subject: [PATCH 103/244] fix(agent): trigger preflight compression on
 few-but-huge sessions (#27405)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The preflight-compression gate only ran the (expensive) token estimate when
the message COUNT exceeded protect_first_n + protect_last_n + 1. A session
with a handful of very large messages never tripped the count condition, so
compression was never attempted and the turn eventually hit a hard
context-overflow error.

Add _should_run_preflight_estimate() with OR semantics: run the estimate when
either the message count exceeds the protected ranges (the historical gate)
OR a cheap char-based estimate already crosses the configured threshold. The
downstream estimate_request_tokens_rough() stays authoritative — this is only
a hint that decides whether to pay for the full estimate.

Salvaged from #27435 by @texhy (authorship preserved). Re-applied on current
main: the preflight gate moved from conversation_loop.py to turn_context.py
since the PR was opened, so the helper + gate are placed there; the test
imports the real MINIMUM_CONTEXT_LENGTH instead of a hardcoded literal.

Closes #27405.

Subject: [PATCH 104/244] fix(gateway): skip non-dict entries in session
 loading (#46994)

Corrupted sessions.json entries (e.g. a bare bool where a dict is
expected) caused TypeError on 'origin' in data' which escaped the
(ValueError, KeyError) inner except and aborted loading ALL remaining
sessions, not just the corrupted one.

Two-layer fix:
- Loop level: isinstance(entry_data, dict) guard before from_dict
- from_dict: isinstance(data['origin'], dict) instead of bare truthiness
- Added TypeError to the inner except as defense-in-depth

Closes #46994

Subject: [PATCH 105/244] fix(delegate): strip cronjob toolset from delegated
 children (#43466)

_strip_blocked_tools used a hardcoded set missing 'cronjob'. Children
on gateway platforms could inherit the cronjob toolset, scheduling
persistent jobs that outlive the delegation despite DELEGATE_BLOCKED_TOOLS.

Fix: derive the strip set from DELEGATE_BLOCKED_TOOLS at runtime so the
two lists can never drift. Add 'cronjob' to DELEGATE_BLOCKED_TOOLS for
documentation consistency. Two regression tests lock the invariant.

Salvaged from #43687 by @riyas22. Adapted test to current main (no
'messaging' toolset exists -- send_message is intentionally not
registered as an agent tool).

Closes #43466

Subject: [PATCH 107/244] fix(ddgs): bound DuckDuckGo search with a wall-clock
 timeout (#36776)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A single ddgs (DuckDuckGo) search could hang indefinitely and block the
shared agent loop — and therefore every platform (CLI, Telegram, Matrix...).
The DDGS constructor's timeout only bounds individual HTTP requests; ddgs's
multi-engine retry loop has no overall cap, so a slow/rate-limited response
could spin for 20+ minutes with no output and no error.

Run the synchronous ddgs call in a single-worker ThreadPoolExecutor and cap
it with future.result(timeout=_SEARCH_TIMEOUT_SECS=30). On timeout, return a
clear failure ("DuckDuckGo search timed out ... try a different provider")
instead of blocking; the pool is shut down with cancel_futures so a hung
worker is never awaited.

Salvaged from #37422 by @uzunkuyruk (authorship preserved). Re-applied on
current main (the PR's provider.py base had diverged). Added a load-bearing
timeout regression test (the original PR only updated the fake's constructor
and had no timeout-behavior test) — mutation-verified to fail without the cap.

Closes #36776.

From 8d1f6debfdb1ab58891c3d8f484f9e241a77ee11 Mon Sep 17 00:00:00 2001
From: liuhao1024 <sunsky.lau@gmail.com>
Date: Thu, 25 Jun 2026 02:06:54 +0530
Subject: [PATCH 108/244] fix(agent): deepcopy plugin context engine to prevent
 parent corruption on delegate_task (#42449)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When delegate_task spawns a child agent with a different model/provider, the
child's init_agent loaded the plugin context-engine GLOBAL singleton by
reference (`_selected_engine = _candidate`) and then called update_model() on
it with the child's (smaller) context_length. Because parent and child shared
the same object, this mutated the PARENT's compressor: e.g. DeepSeek 1M ctx
silently dropped to 204800 and the compression threshold from 200K to 40K
after any delegate_task with a different model.

Deepcopy the singleton before assigning/mutating it (agent_init.py) so the
child gets its own instance and the parent's compressor is untouched.

Salvaged from #42452 by @liuhao1024 (authorship preserved). Added a
source-pin regression test that fails if the production line reverts to the
bare alias, plus an end-to-end test driving get_plugin_context_engine() and a
StubEngine.update_model() — the original PR's tests exercised copy.deepcopy in
isolation but did not guard the actual agent_init code path.

Closes #42449. Supersedes #42469, #42474 (same one-line fix, no test).

Subject: [PATCH 109/244] fix(tools): catch mkdtemp OSError in tirith install
 to prevent unbounded retry and temp-dir leak (#51826)

When tempfile.mkdtemp() raises OSError (e.g. disk full), the exception
propagated past the try/finally block, so _mark_install_failed() was
never called. The 24h backoff marker never engaged, causing unbounded
retry on every command -- each attempt leaked a tirith-install-* temp
directory, eventually filling /tmp completely.

Fix: wrap mkdtemp in its own try/except OSError, returning
(None, "no_space") so the caller's normal failure path (including
_mark_install_failed) executes.

Salvaged from #51831 by @liuhao1024.

Closes #51826

Subject: [PATCH 110/244] fix(agent): validate context/memory tool schemas
 before wrapping

Closes #47707

Context engines and memory providers expose tool schemas via
get_tool_schemas(). agent_init.py wrapped each as
{"type":"function","function":_schema} without validating that
_schema carries a top-level name. A provider returning an entry already
in OpenAI tool form ({"type":"function","function":{...}}) was then
double-wrapped into a tool whose function has no name. Strict providers
(e.g. DeepSeek) reject the entire request with HTTP 400
'tools[N].function: missing field name', so one malformed schema
silently disables the whole toolset and breaks every turn. The schema
was also never added to valid_tool_names, so even lenient providers
could not call it.

Add a shared normalize_tool_schema() helper that unwraps an
already-wrapped entry and returns None for anything lacking a resolvable
string name. Wire it into the agent_init context-engine loop and all
three memory_manager surfaces (inject_memory_provider_tools,
add_provider routing index, get_all_tool_schemas), so a single bad
plugin schema is skipped with a warning instead of poisoning the
request.

Verification: 209 targeted agent/memory tests pass (incl. 9 new).
New tests assert the unwrap + skip-nameless behavior and fail without
the fix.

Subject: [PATCH 111/244] fix(gateway): honor server retry_after in
 _send_with_retry for Telegram flood control (#46762)

When Telegram's sendRichMessage returns a FloodWait/RetryAfter error,
_try_send_rich() now extracts the server-provided retry_after value and
propagates it through SendResult.retry_after. The base _send_with_retry()
layer honors this value instead of using its default short exponential
backoff (~2s, ~4s), preventing the retry budget from being exhausted
against a server that demands a 25-37s wait.

Salvaged from #46774 by @liuhao1024. Telegram adapter path moved from
gateway/platforms/telegram.py to plugins/platforms/telegram/adapter.py
since the original PR.

Closes #46762

Subject: [PATCH 112/244] fix(desktop): make Agents indicator match the
 Spawn-tree panel
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The status-bar "Agents" item conflated three unrelated signals — running
subagents (aggregated across all sessions), in-flight session turns, and
failed background *system* actions (gateway restarts, toolset installs,
computer-use grants via $desktopActionTasks/preview restart) — yet
clicking it opens AgentsView, which renders only subagents. A failed
gateway restart therefore showed "Agents (1 Failed)" over an empty
"No live subagents" tree. AgentsView also filtered to the active session,
so a subagent running in a background session showed "Agents N running"
with nothing in the tree (the desync reported in #49808).

Unify the scope both surfaces speak:
- AgentsView aggregates subagents across every session (salvages #49819).
- The indicator's running/failed counts come from subagents only
  (aggregated), never background system actions — those keep their own
  surfaces in settings / command center.

So "Agents (N …)" now always points at a populated Spawn tree.

Supersedes #49819. Fixes #49808.

Subject: [PATCH 113/244] fix(docker): redirect lazy installs to a durable
 target so opt-in backends work in the immutable image (#51136)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The published Docker image seals the agent venv (root-owned, read-only
/opt/hermes) and sets HERMES_DISABLE_LAZY_INSTALLS=1 so a runtime install
can't mutate and brick the core. But opt-in backends (Firecrawl web search,
Exa, Feishu, ...) deliberately keep their SDKs in tools/lazy_deps.py and out
of [all] (pyproject policy 2026-05-12: one quarantined release must not break
every install). The two policies collided: the SDK isn't baked in AND can't
lazy-install, so the default Firecrawl web_search/web_extract fail out of the
box in Docker (#51136), as do Exa (#49445) and Feishu (#50205).

Fix the whole class instead of baking in one backend: when
HERMES_LAZY_INSTALL_TARGET is set, lazy installs are redirected to a writable
dir on the durable /opt/data volume via `pip/uv install --target`, and that
dir is APPENDED to the end of sys.path. Because the core venv always wins
name collisions, a package installed this way can only ADD new modules — it
can never shadow, downgrade, or break a module the core ships. The worst a
bad/incompatible backend package can do is fail to import and report itself
unavailable; the agent core stays healthy. That structural guarantee is what
made it safe to seal the venv, and it is preserved here even with installs
re-enabled.

- tools/lazy_deps.py: durable-target mode — `--target` install + core-pinned
  `--constraint` file (shared deps resolve to core's versions, conflicts fail
  loudly at install time), append-only sys.path activation, ABI/Python-version
  stamp that wipes the store if an image rebuild bumps the interpreter, and a
  reworked gate so HERMES_DISABLE_LAZY_INSTALLS=1 redirects (rather than hard-
  blocks) when a target is set. security.allow_lazy_installs=false still
  disables installs in every mode.
- hermes_bootstrap.py: activate the durable target on sys.path at first import
  (before any backend imports its SDK) so packages installed on a previous run
  are importable on this run.
- Dockerfile: set HERMES_LAZY_INSTALL_TARGET=/opt/data/lazy-packages.
- docker/stage2-hook.sh: seed + chown the dir on the data volume.
- tests: real-install E2E proving installs land in the target, import cleanly,
  don't leak into the sealed venv, and that a core package is never shadowed;
  ABI-stamp wipe/preserve; gate matrix; Dockerfile/stage2 contract test.

Fixes #51136

Subject: [PATCH 114/244] test(lazy-deps): make durable-target tests
 network-free

CI test shard has no PyPI egress: the real 'pip install packaging==20.9'
in test_core_package_is_not_shadowed failed (the pypi.org reachability
probe passed but the actual install didn't), failing slice 2/6.

- Prove the anti-shadow invariant deterministically: synthesize a fake
  'packaging' in the durable target with a sentinel and assert the import
  still resolves to the core copy (TestCoreNeverShadowed). No network.
- Cover the install wire offline: stub subprocess and assert --target +
  --constraint are built in durable mode and absent in venv-scoped mode
  (TestInstallArgConstruction).
- Gate the genuine PyPI install behind HERMES_RUN_NETWORK_TESTS=1 (opt-in,
  skipped in CI) instead of a flaky reachability probe that doesn't predict
  install success.

Subject: [PATCH 115/244] fix(desktop): wire Ctrl+B voice, declutter voice
 settings, stop endless TTS hang
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three voice-mode papercuts in the desktop app:

1. Ctrl+B did nothing. The docs + `voice.record_key` advertise Ctrl+B to
   talk, but the desktop never bound it (only ⌘B = sidebar existed). Add a
   rebindable `composer.voice` action that toggles the voice conversation,
   defaulting to ⌃B on macOS (distinct from ⌘B; off-macOS `ctrl` folds to
   the sidebar chord, so it ships unbound there to avoid stealing it). The
   global keybind reaches the composer through a new focus-bus event.

2. The Voice settings page rendered every provider's options at once (~30
   fields). Filter to the *selected* TTS/STT provider's sub-fields; STT
   provider fields hide when STT is off. Picking "edge" now shows just the
   Edge voice, making it obvious voice chat also needs STT enabled.

3. Voice mode could hang "speaking" forever. Free Edge TTS sometimes returns
   audio that never fires `playing`/`ended`/`error`, so the playback promise
   never settled. Add a stall watchdog (rearmed on each progress tick, so
   long speech is never cut off) that rejects a stuck stream, letting the
   loop recover with a clear error.

Subject: [PATCH 116/244] fix(desktop): give the gateway reconnect loop an
 escape hatch
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When a remote gateway dropped after a healthy boot (internet loss,
sleep/wake, VPS restart), use-gateway-boot retried with backoff forever
and never surfaced an error. The renderer sat behind the fullscreen
CONNECTING overlay with gatewayState non-open and boot.error null — no
way to reach Settings, sign in again, or switch to a local gateway. To
the user the app was simply broken on connection loss.

Raise a recoverable boot error once the reconnect loop crosses
RECONNECT_ESCALATE_AFTER (6 attempts, ≈45s), so the BootFailureOverlay
(Retry / Sign in / Use local gateway) replaces the dead-end CONNECTING
screen. The loop keeps retrying underneath; the next successful reconnect
(or a manual/wake-driven one) clears the error and dismisses the overlay.

This implements the contract already specified — but never wired up — in
use-gateway-boot.test.tsx (desktop vitest isn't in CI, so the failing
"FIX:" specs went unnoticed). All 4 hook tests + the 3 connecting-overlay
tests pass.

Subject: [PATCH 117/244] fix(desktop): let the session watchdog heal a stuck
 "looping" turn
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The 8-minute stream-silence watchdog only removed a stuck session from
$workingSessionIds (the sidebar dot). The composer's busy state lives in
the session-state cache and was never cleared, so a hung or looping turn
that never delivered its terminal event — including an old session
re-opened while the backend still reports it "running" — stayed wedged on
"Thinking" / Stop indefinitely.

Have the watchdog notify subscribers when it force-clears a session, and
subscribe from the session-state cache to also drop that session's
busy/awaiting/needsInput flags. updateSessionState re-syncs $busy when the
healed session is the one on screen, so the composer recovers instead of
spinning forever.

Frontend-only safety net; doesn't touch the turn lifecycle. The backend
root (a stale in-memory session["running"] surviving a dead turn thread
and re-arming busy on every resume) is a separate follow-up.

Subject: [PATCH 118/244] fix(relay): authorize relay inbound via
 connector-enforced upstream authz
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A hosted instance fronted by the Team Gateway connector dropped EVERY relay
message as "Unauthorized user" and the agent never replied — despite the
message routing correctly through the connector to the instance.

Root cause: gateway authorization (_is_user_authorized) had no notion of
upstream-enforced authz. Platform.RELAY matches no {PLATFORM}_ALLOWED_USERS
allowlist and isn't in the HA/WEBHOOK always-authorized set, so a relay user
with no env allowlist configured hit the default-deny ("No user allowlists
configured. All unauthorized users will be denied."). The message was received,
then silently denied before reaching the agent.

This is incorrect for relay: the connector authenticates the gateway's WS with
a per-instance secret and performs owner-only author-binding resolution BEFORE
delivering. A message only reaches this gateway because the connector resolved
it to THIS instance's bound user (user_instance_binding), keyed on the author id
the connector OBSERVED off the event — never a gateway claim. The authorization
decision is already made by a trusted, authenticated upstream; there is no local
RELAY_ALLOWED_USERS allowlist to consult, and default-denying for its absence is
the bug.

Fix: add a generic BasePlatformAdapter.authorization_is_upstream capability
(default False) that the relay adapter overrides to True, plus a dedicated
trusted branch in _is_user_authorized that honors it. This is delegation to a
trusted upstream, NOT a fail-open: it fires only for an adapter that explicitly
declares the flag; every direct network-exposed adapter leaves it False and the
env-allowlist default-deny (SECURITY.md §2.6) is unchanged. Distinct from
enforces_own_access_policy, which mirrors a LOCAL config-driven allowlist —
this delegates to an authenticated upstream's decision.

Tests: behavior contract that the base defaults False, the relay adapter
declares True, a relay user (group + DM) is authorized with no env allowlist,
and crucially a non-upstream adapter with no allowlist still default-denies
(guards against the fix becoming a blanket fail-open). 6 new tests; relay +
authz + config-policy suites green (134 + 90).

Found via live staging debug of the Discord self-serve onboarding flow.

Subject: [PATCH 119/244] feat(pets): polish generate flow and reduce hatch CPU
 pressure

Ship the final pet-generation UX polish (provider picker behavior, step-2 cancel flow, banner integration, and visual consistency) and make saturated-chroma background removal C-op driven so hatch processing no longer hammers the machine during long runs.

Subject: [PATCH 120/244] fix(desktop): don't report a bogus update count for a
 shallow checkout

The desktop installer clones with `--depth 1`, so a public install's local
history often shares no merge-base with the freshly fetched origin tip. In
that state `git rev-list HEAD..origin/<branch> --count` enumerates the
entire remote ancestry and returns a meaningless huge number, surfacing as
e.g. "v0.17.0 (+12104)" in the update indicator (#51922).

The official-SSH branch of checkUpdates() already sidesteps this by reporting
a binary up-to-date check (`behind: currentSha === targetSha ? 0 : 1`), and
hermes_cli/banner.py guards the identical class for the CLI banner. The
passive desktop count path was the one place the shallow guard was missing.

Detect shallow + no-merge-base up front and fall back to the same SHA-based
binary check; full clones (developers / Docker dev images) keep the exact
count path unchanged. The resolution logic lives in a pure update-count.cjs
helper so it is unit-testable without booting Electron.

Subject: [PATCH 121/244] fix(desktop): skip the rev-list count when it is
 discarded anyway

checkUpdates() ran `git rev-list HEAD..origin/<branch> --count`
unconditionally in the parallel probe batch, even on the shallow +
no-merge-base path where resolveBehindCount() ignores the result and
falls back to a SHA compare. In the #51922 failure mode that count walks
the entire remote ancestry (thousands of commits), so the work was pure
latency on every update check for the exact case the fix targets.

Split the probes into two phases: resolve --is-shallow-repository and
merge-base first, then run rev-list --count only when shouldCountCommits
says the number is meaningful (full clone, or shallow-with-merge-base).
The shallow/no-merge-base SHA fallback is preserved unchanged.

Subject: [PATCH 122/244] fix(update): announce gateway drain waits so desktop
 updates don't look hung
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On macOS, the desktop updater's stage 1 (hermes update --gateway) ends by
restarting running gateways. launchd_restart() SIGTERMs the gateway and
silently waits up to agent.restart_drain_timeout (default 180s) for the
drain; the manual profile-gateway loop waits its drain budget per gateway
the same way. Neither path prints anything before the wait, so the desktop
updater's live output goes dead for minutes right after '✓ Update
complete!' — users read it as a hung update and force-kill their gateway
processes to make it move (#44515). The systemd branch already announces
its drain ('draining (up to Ns)...'); launchd and the manual loop did not.

Print the stop/drain (with PID and budget) before the wait in both paths,
mirroring the systemd branch, and assert the message in the existing
launchd drain test.

Fixes #44515

Subject: [PATCH 123/244] fix(desktop): route gateway restart / status / update
 to the active profile
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

restartGateway, getActionStatus, getStatus, updateHermes and
checkHermesUpdate all hit window.hermesDesktop.api WITHOUT spreading
profileScoped() — unlike their siblings (getModelInfo, setModelAssignment,
grantComputerUsePermissions). _apiProfile tracks the active gateway
profile, and the Electron proxy uses request.profile to pick which pooled
/ remote backend serves the call.

So for a multi-profile or global-remote user, the System-panel "Restart
gateway" (and its status poll, plus Update / status reads) targeted the
primary/default backend instead of the one they're on: the restart hit
the wrong gateway and the poll never saw the action → it looked like
restart silently failed. Single-profile users are unaffected
(profileScoped() returns {} when no profile is active).

Add ...profileScoped() to the five backend-action helpers so they follow
the active profile like the rest of the API surface.

Subject: [PATCH 124/244] fix(desktop): hide platform/internal toolsets from
 the Skills & Tools list
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GET /api/tools/toolsets returns the full CONFIGURABLE_TOOLSETS set with no
desktop curation, so the Skills & Tools → Toolsets list shows entries that
don't belong in a flat per-user toggle: platform-coupled toolsets (discord,
discord_admin, yuanbao — which `hermes tools` already platform-restricts off
the CLI) and internal plumbing (context_engine, moa). `hermes tools` curates
these out; the desktop didn't.

Add a small documented block-list + predicate (mirroring
desktop-slash-commands.ts) and apply it in the toolset list filter. Hiding a
row is cosmetic — enabled state and runtime gating are untouched.

Subject: [PATCH 125/244] fix(desktop): stop the update overlay looking frozen
 while it works
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two ways the update overlay read as stuck even though the update was
streaming progress underneath:

- In-app (macOS/Linux) UpdatesOverlay: runStreamedUpdate forwards every
  stdout line as a progress event with percent: null, and ingestProgress
  wrote that straight through — clobbering the milestone percents (10/60)
  so the bar fell back to indeterminate on every log line. Keep the last
  percent when a line carries null.

- Staged install/update overlay: the bar is completedCount / totalCount,
  which counts only *finished* stages, so a long first stage pinned it at
  "0 of 2" / 0% until the stage ended. Count the running stage as half a
  unit so the bar advances during the stage (the per-stage spinner already
  shows which step is live).

Both are display-only; no stage/event semantics change. (The Windows
hermes-setup Tauri progress UI in apps/bootstrap-installer has the same
counter-only-on-completion logic — parity follow-up.)

Subject: [PATCH 128/244] fix(gateway): scope dashboard liveness fallback to
 the profile
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PR #52151 hardened the runtime-status liveness check to trust a readable
live process command line over stale gateway_state.json argv, so a recycled
PID now owned by an s6 supervisor no longer counts as a running gateway.

That fix is correct but incomplete for the reported symptom: the web
dashboard showed a named profile's gateway green while
`hermes -p <name> gateway status` showed it stopped. Two further issues:

1. Cross-profile PID reuse. In per-profile Docker supervision, one profile's
   stale `gateway_state.json` can record a PID the OS later recycled onto a
   DIFFERENT profile's live gateway. That PID's command line still
   `looks_like_gateway`, so the dead profile was reported running. The
   recorded argv has its `-p <name>` selector stripped in-process by
   `_apply_profile_override`, so it cannot disambiguate; the live `/proc`
   cmdline still carries it. `get_runtime_status_running_pid` now accepts an
   `expected_home` and validates the live command line belongs to THAT
   profile (mirroring `hermes_cli.gateway._matches_current_profile`, the
   logic the CLI scan path already uses — which is why the CLI was correct).
   `_check_gateway_running` passes the enumerated profile dir.

2. The existing regression test `test_gateway_running_check_falls_back_to_
   runtime_state` used the live pytest PID with a gateway-shaped record; once
   the live cmdline became authoritative it no longer looked like a gateway.
   Updated to mock the live cmdline to the real separate-process scenario it
   describes.

The active-profile path (`get_running_pid`) is intentionally left unscoped:
it is lock-verified and any live gateway cmdline is acceptable there. Multiplex
mode is unaffected — `running` state is only ever written to a gateway's own
home, never a secondary served profile's.

Adds coverage for: cross-profile PID reuse (named + default), matching
profile cmdline (`-p`, `--profile`, explicit HERMES_HOME=), the bare default
gateway, and the unreadable-cmdline cross-platform fallback. Each new
cross-profile assertion fails without the profile scope and passes with it.

Subject: [PATCH 129/244] fix(pets): make inline generate cancel discard draft
 flow

Wire the sparkle generate button's cancel action to the same discard/reset path as step-2 cancel so abort semantics are consistent and always return to step 1 while retaining the prompt input.

Subject: [PATCH 130/244] test(delegate): harden heartbeat in-tool stale timing
 assertion

Stabilize the long-running-tool heartbeat test by patching stale thresholds inside the test and asserting the heartbeat exceeds the idle ceiling, which preserves intent while removing scheduler-sensitive assumptions that flake in CI.

Subject: [PATCH 133/244] fix(desktop): stop refText crash on undefined
 composer attachment holes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A session switch or draft restore can leave undefined/null holes in the
composer attachments array. AttachmentList was guarded against this in
#49624, but the sibling submit path was not: submitPromptText maps the
same array through attachmentDisplayText/optimisticAttachmentRef and
buildContextText (a.kind / a.label / a.refText), so a hole threw
"Cannot read properties of undefined (reading 'refText')" — an uncaught
renderer error that blanks the chat pane and shows "Desktop app link
offline".

Close the whole bug class:
- attachmentDisplayText / optimisticAttachmentRef no-op on a falsy
  attachment (shared chokepoint, also protects thread.tsx drop handler).
- submitPromptText filters falsy entries from the source array, and
  buildContextText filters its (possibly post-sync) input before reading
  fields.

Subject: [PATCH 134/244] test(desktop): cover undefined/null attachment holes
 in ref helpers

Regression for the refText crash: attachmentDisplayText and
optimisticAttachmentRef must return null (not throw) when handed an
undefined/null attachment hole, so the submit path can't reproduce
"Cannot read properties of undefined (reading 'refText')".

Subject: [PATCH 135/244] feat(relay): add go_dormant() transport mode for
 scale-to-zero (0.E0)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Net-new WebSocketRelayTransport.go_dormant() + RelayAdapter.go_dormant() —
the third transport mode the scale-to-zero behaviour layer needs, distinct
from both disconnect() and an unexpected close (decisions.md D12/F14):

- disconnect() sets _closing=True and CANCELS the reconnect supervisor
  (terminal "shutting down for good") -> a suspended machine never re-dials
  on wake, stranding its buffered backlog.
- an unexpected close re-dials IMMEDIATELY -> the socket never stays down,
  so the platform proxy never suspends the machine.

go_dormant(): going_idle->ack (reuse go_idle), then close the socket WITHOUT
setting _closing, so the reader's fall-through still arms the reconnect
supervisor (wake path stays live) but on the longer _dormant_redial_s
cadence so it doesn't fight the platform suspend window. A successful re-dial
clears _dormant. Honors the §3.4 wake->reconnect->drain contract.

Tests: 6 new in test_relay_going_idle.py incl. the F14 regression guard
(routing dormancy through disconnect() fails exactly the 4 wake-path tests).
Full relay suite 140 passed.

Subject: [PATCH 136/244] feat(gateway): scale-to-zero idle detection +
 dormant-quiesce (Phase 0)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The gateway-side BEHAVIOUR layer that consumes the relay scale-to-zero
primitives (gateway-gateway Phase 5): the gateway decides it is idle and
drives the relay transport dormant so the platform (Fly autostop:"suspend")
can suspend the now-traffic-idle machine, which wakes on the connector's
wakeUrl poke (decisions.md Q3=C', D1-D13).

- gateway/scale_to_zero.py: pure helpers — scale_to_zero_enabled (the NAS
  Labs HERMES_SCALE_TO_ZERO stamp, D11/Q8=A), parse_idle_timeout_seconds
  (config.yaml gateway.scale_to_zero.idle_timeout_minutes, D2),
  messaging_is_relay_only_or_absent (F6/D1), should_arm (D1/D11/§3.4(1)),
  is_idle (D2/D3/F7).
- gateway/run.py: _last_inbound_at clock stamped on user inbound in
  _handle_message (F13); the arm-gate + idle predicate + the
  _scale_to_zero_watcher dormant sequence (mark draining -> adapter
  go_dormant() -> cooldown), started only when armed. Deliberately NOT the
  stop path and NOT mark_resume_pending (F12/D13).
- tools/process_registry.py: has_any_active() for the bg-work guard (D3/F7).
- hermes_cli/config.py: gateway.scale_to_zero.idle_timeout_minutes default 5.

Tests: 38 pure-logic + 6 watcher (incl. bg-work regression guard proven RED).
Full relay + scale-to-zero suites: 184 passed. The 20 unrelated failures in
the broader run are PRE-EXISTING on origin/main (custom-provider/tools tests),
confirmed via a pristine baseline worktree.

+"""Scale-to-zero idle detection + dormant-quiesce for the gateway (Phase 0).
+
+This is the gateway-side BEHAVIOUR layer that consumes the relay scale-to-zero
+PRIMITIVES (gateway-gateway Phase 5: the buffered-flip, the durable per-instance
+buffer, the wakeUrl poke, the reconnect supervisor). It owns the *decision* to go
+idle and drives the relay transport's ``go_dormant()`` (D12) — it does NOT itself
+suspend the machine. On Fly, the now-traffic-idle machine is suspended by
+``autostop:"suspend"`` and woken by autostart-on-wakeUrl (decisions.md Q3=C′).
+
+Design constraints (decisions.md):
+  - Per-instance enable is gated SOLELY by the NAS "Labs" toggle, carried to the
+    gateway as the ``HERMES_SCALE_TO_ZERO`` env stamp (D11/Q8=A). NOT a user
+    config key; ``scale_to_zero.idle_timeout_minutes`` IS config.yaml (D2).
+  - Arm only when messaging is relay-only or absent (D1/F6) AND a wakeUrl is
+    registered (§3.4(1)) AND the flag is set.
+  - Idle = no in-flight agent turn AND no inbound for N min AND no live
+    background work (D2/D3/F7).
+  - The quiesce uses ``go_dormant()`` (socket closed + supervisor preserved),
+    NEVER the stop/restart drain or ``disconnect()`` (F12/F14). The process stays
+    alive; Fly freezes+resumes it.
+  - ``mark_resume_pending`` is deliberately NOT called here (D13 — suspend
+    preserves RAM; revive only if we move to autostop:"stop" or see kills).
+
+The pure helpers (``parse_idle_timeout_seconds``, ``scale_to_zero_enabled``,
+``messaging_is_relay_only_or_absent``, ``is_idle``, ``should_arm``) take plain
+inputs so they unit-test without a live gateway.

Subject: [PATCH 137/244] fix(tui): route /learn through command.dispatch so
 the prompt fires (#52232)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Desktop GUI (tui_gateway) slash worker subprocess has no reader for
the CLI's _pending_input queue. /learn's CLI handler prints the ack and
puts the built prompt onto that queue, so in the TUI the prompt was
silently dropped — ack shown, no LLM turn, no skill created (#51829).

command.dispatch already handles 'learn' correctly (returns
{type: send, message: build_learn_prompt(arg)}), but 'learn' was missing
from _PENDING_INPUT_COMMANDS, so slash.exec fell through to the worker
instead of routing to command.dispatch. Add it to the frozenset, matching
the existing goal/queue/steer/plan pattern.

Subject: [PATCH 138/244] fix(soul): installers seed the real default persona,
 upgrade legacy empty templates (#52246)

The desktop bootstrap (and curl/PowerShell/docker installs) seeded
~/.hermes/SOUL.md with a comment-only scaffold that contained no persona
text. That shadowed the runtime default (_ensure_default_soul_md ->
DEFAULT_SOUL_MD), since seeding is guarded by 'if SOUL.md doesn't exist'.
Result: every fresh installer install got the empty template instead of
the documented Hermes persona; desktop just made it visible in onboarding.

- install.sh / install.ps1 / docker/SOUL.md now write DEFAULT_SOUL_MD.
- _ensure_default_soul_md() upgrades a SOUL.md still matching the known
  legacy scaffold in place; customized files (any deviation, incl. a
  persona appended below the comment) are never touched.
- Detection normalizes CRLF/BOM so Windows-installer drift still matches.

Subject: [PATCH 139/244] fix(terminal): sanitize host/relative cwd OVERRIDE
 before it reaches docker run -w (#50636)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

terminal_tool() resolves a per-task cwd override that WINS over config["cwd"]:

    cwd = overrides.get("cwd") or config["cwd"]

config["cwd"] is sanitized for container backends in _get_env_config() (host
prefixes /Users//home//C:\\/C:/ and relative paths are replaced with the
backend default /root). But the override was applied RAW — it was never run
through that guard. The gateway/TUI registers the host launch dir as a cwd
override for workspace tracking (tui_gateway/server.py _register_session_cwd
-> _terminal_task_cwd -> _session_cwd -> os.getcwd()), so on a container
backend a host path leaked straight to `docker run -w <host-path>`:

  - Windows desktop: -w C:\Users\<user>  -> container fails to start (exit 125)
  - POSIX:           -w /home/<user>      -> same

The ACP adapter translates its override cwd (acp_adapter/session.py
_translate_acp_cwd), but the gateway path did neither translation nor
sanitization, so the override bypassed the one guard that would have caught it.

Fix: extract the host/relative-path predicate into a shared
_is_unusable_container_cwd() helper (so the existing _get_env_config()
sanitizer and the new guard can't drift), and re-apply it to the *resolved*
cwd at the override-resolution site. Valid in-container override paths
(RL/benchmark sandboxes that set cwd to /workspace, /root, ...) are absolute
non-host paths and pass through untouched.

Tests: unit-pin the predicate (Windows backslash/forwardslash, POSIX home,
macOS /Users, relative, valid container paths) AND an E2E call-site pin that
drives terminal_tool() with a host-path override registered and asserts the
cwd reaching _create_environment is sanitized. Mutation-verified: reverting
the call-site guard makes the two host-path E2E tests fail (showing the raw
host path leaking) while the valid-/workspace-override test stays green.

Subject: [PATCH 140/244] fix(relay): re-attach DM author user_id on outbound
 for connector egress
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A DM reply carries no guild_id, so the connector's egress guard cannot
resolve the owning tenant from metadata.guild_id and declines the send
with "discord egress declined: target not routed to an onboarded tenant"
— the bug behind "the bot never replies in DMs". Guild replies are
unaffected (they carry guild_id), which is why the guild path worked
end-to-end while DMs looked broken.

The connector now resolves a DM reply's tenant from the recipient's
author binding (gateway-gateway #67, resolveByUser keyed on
metadata.user_id) — the outbound counterpart to inbound Phase 7a
author-first resolution. But it needs the recipient user_id ON the
outbound action, and the adapter only re-attached guild_id
(_capture_scope/_with_scope), no-op for DMs (the docstring even said so).

This extends the adapter's inbound-scope capture: for a DM (no guild_id)
remember chat_id -> the authentic author user_id we observed, and
re-attach it as metadata.user_id on outbound. Guild capture is unchanged
and wins when present; user_id is the DM-only fallback. The id is the one
the connector observed inbound (never gateway-asserted), so the trust
invariant holds.

+4 unit tests (DM reply re-attaches user_id + no guild_id; unknown chat
invents nothing; explicit user_id preserved; guild reply never carries
user_id). Proved load-bearing (reverting the re-attach fails the DM
test). 144 relay tests pass, ruff clean.

Pairs with gateway-gateway #67 (the connector-side resolver). Together
they close the DM-reply egress gap end-to-end.

Subject: [PATCH 141/244] perf(desktop): bound tool-result rendering so big
 /learn runs don't freeze (#52273)

ToolFallback rebuilt the `part` wrapper every render, defeating the
buildToolView memo and re-running a full JSON.stringify of the result on
every ~33ms stream delta. A /learn over a large directory (many ~100KB
tool results) saturated the renderer main thread (hang/throttle) and
spiked memory until it OOMd (crash).

- Re-derive a stable `part` from the referentially-stable args/result so
  the view/copy memos hold across deltas.
- Clamp every inline-painted payload (detail, stdout/stderr, rawResult,
  technical trace) to MAX_TOOL_RENDER_CHARS; the row's Copy button still
  reads the uncapped view.detail for the full output.

Subject: [PATCH 144/244] feat(cron): optional mirror of cron delivery into
 target chat session
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds an opt-in path so a cron job's delivered output is also appended to
the TARGET chat's gateway session transcript (as an assistant turn), so a
user reply to a recurring delivery (daily brief, reminder) is answered with
the delivery in context instead of 'what is that?' amnesia.

- Reuses the shipped gateway.mirror.mirror_to_session — the same primitive
  interactive send_message mirroring already uses. No messaging-toolset
  change (cron still can't call send_message; this rides delivery).
- Gated: per-job attach_to_session overrides global cron.mirror_delivery
  (config.yaml). Default OFF — historical isolation preserved byte-for-byte.
- Mirrors the CLEAN agent output, not the cron header/footer wrapper.
- Alternation/cache-safe: append lands at a turn boundary, never mid-loop,
  never mutates the cached system prompt. Cold-start (no target session)
  is a silent no-op; mirror errors never fail a successful delivery.
- Surfaced on the cronjob tool (attach_to_session) + config schema.

Driven by enterprise cron-as-control-plane use case. 10 new tests; full
cron + cronjob-tool suites pass (600).

Subject: [PATCH 145/244] refactor(cron): scope delivery mirror to the origin
 conversation

The cron->session mirror now fires ONLY for the delivery target that
equals the job's origin (platform+chat_id[+thread_id]). A job created
from a live gateway chat stamps that chat as origin, and that session is
guaranteed to exist (it is the conversation the user scheduled the job
in). Fan-out / broadcast / home-channel-fallback targets are never
mirrored: they are not a continuation of a conversation and may have no
session at all.

This makes the prior 'cold-start session seeding' concern a non-case by
construction: when the mirror semantically applies the session exists;
when none exists the target was never the origin, so we no-op.

Adds _target_matches_origin() + origin-scoping tests (exact match,
other-chat/other-platform/no-origin rejection, thread scoping, fan-out
mirrors only the origin target).

Subject: [PATCH 146/244] feat(cron): pass origin user_id to delivery mirror
 (send_message parity)

Multi-participant parity with interactive send_message, which passes
HERMES_SESSION_USER_ID to gateway.mirror.mirror_to_session so the mirror
lands in the exact participant's session.

- cronjob_tools._origin_from_env now captures user_id from the session
  context at job-create time (alongside platform/chat_id/thread_id).
- _maybe_mirror_cron_delivery forwards user_id to mirror_to_session.
- _deliver_result threads origin.user_id through for the origin target.

Effect: in a per-user-isolated group chat (group_sessions_per_user=True,
the default), the mirror resolves to the member who scheduled the job
instead of conservatively no-op'ing on ambiguous candidates. DMs and
shared group/thread sessions are unaffected (single candidate). Default
still OFF.

Tests: helper forwards user_id; E2E _deliver_result forwards origin
user_id. 17/17 in TestCronDeliveryMirror; 527 cron tests pass (4 failures
pre-existing: croniter-not-installed + TZ, identical on baseline).

Subject: [PATCH 147/244] feat(cron): thread-preferred continuable delivery
 (open a thread, mirror DM fallback)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Continuable cron jobs (attach_to_session / cron.mirror_delivery, default
OFF) now prefer a dedicated thread on thread-capable platforms, falling
back to origin-DM mirroring where threads don't exist.

- Thread-capable (Telegram topics, Discord/Slack threads): open a fresh
  thread for the job via the shipped adapter.create_handoff_thread,
  route the brief into it, and seed the thread-keyed session so the
  user's in-thread reply continues with full context. This is the
  'continuable cron opens its own thread' interface.
- DM-only (WhatsApp/Signal/SMS): create_handoff_thread returns None ->
  fall back to mirroring into the origin DM session (existing behaviour).

Reuses existing infrastructure end-to-end — no new adapter surface, no
provider-chain signature change:
- adapter.create_handoff_thread (already implemented per-platform,
  returns None on unsupported platforms = the fallback signal)
- the live SessionStore via adapter._session_store (already set on every
  adapter), reached without threading a new param through the frozen
  CronScheduler.start() contract
- gateway.mirror.mirror_to_session for the seed/append
- existing per-target delivery routing carries the new thread_id for free

Mirrors GatewayRunner._process_handoff's open-thread-or-fallback +
seed pattern, standalone for the cron delivery path. thread_seeded
guards against a double-mirror after seeding. Scoped to the origin
target only; fan-out/broadcast targets are never threaded or mirrored.

Config docs updated (cron.mirror_delivery) + cronjob tool
attach_to_session description reframed around continuable/thread-preferred.

Tests: +5 (thread id returned on thread platform; None on DM platform;
None without capability/loop; seed creates thread session + mirrors;
seed no-op on empty). 22/22 in TestCronDeliveryMirror; 532 cron tests

Subject: [PATCH 148/244] fix(cron): mirror continuable cron as a labelled user
 turn (alternation-safe)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Addresses review on #51077 (kxee). The continuable-cron mirror reused
gateway.mirror.mirror_to_session, which writes role=assistant — re-
introducing the exact alternation violation #2313 (37a997945)
deliberately removed: a cron brief landing as assistant after the
agent's last turn yields assistant->assistant, which breaks strict-
alternation providers (OpenAI/OpenRouter) per issue #2221. The mirror/
mirror_source metadata is also dropped at the SQLite boundary, so the
[Delivered from cron] label is lost on replay.

This is an intentional, opt-in (default OFF) reversal of #2313's
'cron output does not belong in interactive history' for the reply-to-
cron use case — gated behind cron.mirror_delivery / attach_to_session.

Fixes:
- mirror_to_session gains a role param (default 'assistant' — interactive
  send_message mirror unchanged, it IS the agent speaking). Cron paths
  pass role='user' with a '[Cron delivery: <task>]' prefix so the brief
  collapses via repair_message_sequence's consecutive-user merge on every
  provider, and stays distinguishable on replay despite the metadata drop.
- thread_seeded: defer seeding + the flag until delivery into the new
  thread actually succeeds. Previously set pre-delivery, so an open-
  succeeds / deliver-fails case both stranded a seeded-but-unseen brief
  AND suppressed the DM-fallback mirror.
- seed mirror now passes user_id='system:cron' to resolve the exact
  thread-keyed session row it just created.
- dedupe the duplicate BasePlatformAdapter import in _deliver_result.
- trim oversized docstrings to non-obvious WHY (AGENTS.md).
- docs: document cron.mirror_delivery / attach_to_session in
  website/docs/user-guide/features/cron.md.
- test: assert the cron mirror writes role='user' with the label prefix.

204 cron+mirror tests pass.

+### Continuable jobs (reply to a cron delivery)
+
+By default a cron delivery is fire-and-forget: the message is sent, but it does
+not live in the chat's conversation history, so if you reply to it the agent
+has no record of what it said. Set a job **continuable** and the delivered brief
+becomes a conversation you can reply into — the agent has the brief in context
+instead of asking "what is Task #2?".
+
+Opt-in, **default off**. Enable globally in config, or per-job via the `cronjob`
+tool's `attach_to_session` (which overrides the global setting for that one job):
+
+```yaml
+# ~/.hermes/config.yaml
+cron:
+  mirror_delivery: false   # set true to make cron deliveries continuable
+```
+
+Behaviour is **thread-preferred**, scoped to the job's origin chat:
+
+- **Thread-capable platforms** (Telegram topics, Discord/Slack threads): each
+  delivery opens its own dedicated thread and the brief is seeded into that
+  thread's session, so a reply in-thread continues with full context. A
+  recurring job (e.g. a daily brief) opens a fresh thread per run, keeping each
+  delivery's follow-up discussion isolated.
+- **DM-only platforms** (WhatsApp, Signal, SMS): no threads exist, so the brief
+  is mirrored into the origin DM session instead — the DM itself is the
+  continuation surface.
+
+Only the origin chat is ever touched: fan-out / broadcast targets (`all`,
+explicit other-chat deliveries) are never made continuable. The mirror is
+written as a labelled user turn (`[Cron delivery: <task name>]`), which keeps
+the conversation history alternation-safe across all model providers.
+
 ### Silent suppression
 
 If the agent's final response contains `[SILENT]`, delivery is suppressed entirely. The output is still saved locally for audit (in `~/.hermes/cron/output/`), but no message is sent to the delivery target.

Subject: [PATCH 154/244] feat(pets): quality-first OpenRouter model chain +
 stronger atlas gates + global pet-gen notifications

OpenRouter/Nous image gen now runs a quality-first model chain by default:
attempt the highest-fidelity OpenAI image model first, then fall back to
Gemini 3 Pro Image when it's access-gated/unavailable/times out. An explicit
OPENROUTER_IMAGE_MODEL / config model override pins one model with no fallback.

Atlas validation rejects malformed model output instead of shipping it: adds a
per-state collapse guard (a single sliver/fragment row no longer passes because
other rows are healthy), on top of the existing postage-stamp + multi-pose
checks.

Desktop: pet-gen native notifications are now "global" (not tied to a chat
session), so a background generation started from the command center fires an
OS notification when the user is away even with no active session. Adds a
neutral "This can take up to 5 minutes." banner on step 1, and lets the
provider picker auto-size.

Tests updated/added for the OpenRouter fallback chain, the collapse guard, and
the global notification path.

Subject: [PATCH 155/244] fix(relay): authorize relay-delivered events by
 delivery, not source.platform (#52306)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(relay): authorize relay-delivered events by delivery, not source.platform

The #52190 upstream-authz fix keyed _is_user_authorized off
source.platform via _adapter_authorization_is_upstream(source.platform).
But a relay *message* inbound carries the UNDERLYING platform
(source.platform == discord/telegram/...), NOT Platform.RELAY, because
ws_transport._event_from_wire maps the connector's wire payload
(platform="discord") straight onto SessionSource for session-keying and
egress. The relay adapter is registered only under Platform.RELAY, so
adapters.get(Platform.DISCORD) misses, the trusted-upstream branch is
skipped, and the user hits the env-allowlist default-deny:

    WARNING gateway.run: Unauthorized user: <id> (<name>) on discord

(Live staging bug: alpha tester linked successfully, then every
follow-up DM was silently dropped.)

Fix: the authentic trust signal is that the event was delivered over the
per-instance-authenticated relay WS, not which platform it underlies. Add
a wire-INVISIBLE SessionSource.delivered_via_upstream_relay flag, stamped
by the relay transport in _event_from_wire, and authorize on it. The flag
is excluded from to_dict/from_dict so a peer can neither forge it across
the wire nor have it restored from persistence. The existing adapter-flag
check is retained for events whose source.platform IS Platform.RELAY
(interaction-passthrough). A direct Discord event on a multiplexing
gateway (direct + relay adapters) is unmarked and still default-denies.

* fix(relay): use identity check on delivery marker to avoid MagicMock fail-open

A MagicMock() source (used by test_signal.py and other gateway tests) auto-
vivifies source.delivered_via_upstream_relay as a truthy Mock, which a bare
truthiness check would treat as authorized — flipping
test_signal_in_allowlist_maps from False to True. The marker is a real bool on
SessionSource, so check 'is True' explicitly: refuses to authorize any non-bool
stand-in, defensive against accidental fail-open.

Subject: [PATCH 156/244] fix(cache): content-address prompt_cache_key so
 recurring cron jobs reuse the warm prefix (#52295)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Recurring cron jobs were prompt-cache-cold on every fire. session_id is
built as cron_<job_id>_<timestamp>, and the Codex/Responses transport used
session_id directly as prompt_cache_key — so the timestamp changed the cache
key on every run and the static prefix (agent identity + tool schemas) was
re-paid each tick.

Derive prompt_cache_key from a SHA-256 of the static prefix (instructions +
sorted tool schemas) instead. Repeated fires of the same job share one
content-addressed key (pck_<hash>) and reuse the warm prefix within the
provider's cache TTL. The key changes exactly when the prefix changes —
edit the job's prompt or toolset and it re-keys; leave it alone and it stays
stable.

session_id is left untouched for transcript isolation, log correlation, and
the Codex/xAI session-scope routing headers (session_id, x-client-request-id,
x-grok-conv-id) — those are the per-fire identity, not the cache key. Only the
prompt_cache_key body field (standard OpenAI/Codex path and the xAI extra_body
field) is content-addressed.

Closes #51395.

Subject: [PATCH 157/244] fix(desktop): compact tool row titles

Make completed desktop tool rows read like useful activity labels instead of raw plumbing: terminal rows use a dispatch-style shell summarizer for agent wrappers, and read_file rows keep the action plus filename and requested line range.

The shell cleanup follows condensed-milk-pi's shape: split command compounds on real separators, strip pipe tails inside each segment, clean redirects/env prefixes, then classify setup/banner/status segments. Multi-command probes render as `first command + N commands`; the full command remains available in copy/detail.

Read rows now render as `Read package.json` or `Read main.ts L25-34`, using requested positive offset/limit and returned line numbers only as fallback for negative/unknown offsets.

Subject: [PATCH 158/244] fix(pets): raise generation timeouts for the slow
 quality-first model path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The quality-first default (OpenAI image via OpenRouter) is slow, and a full
hatch fans out ~8 rows with up to 3 retries each (300s/call) across 2 parallel
waves, so the absolute backend worst case is ~30 min. The old ceilings fired
mid-run:

- per-image HTTP call: 180s -> 300s (a single cold row can exceed 3 min)
- drafts RPC: 240s -> 420s (single wave, no retries — 7 min is ample)
- hatch RPC: 420s -> 1hr (sits above the ~30 min backend worst case)

The hatch ceiling is intentionally well above the realistic max so the frontend
never throws "request timed out" before the backend has exhausted its own
retries. The background-resumable notification path remains the real UX safety
net — the user can close the modal and get pinged on completion.

Subject: [PATCH 159/244] fix(pets): soften step-1 ETA copy to "several
 minutes"

The fixed "up to 5 minutes" wording undersells the slow quality-first path
(OpenAI image via OpenRouter), where a full hatch can run far longer. Use an
open-ended "several minutes" instead so the banner stays honest across the
fast and slow providers.

Subject: [PATCH 160/244] test(pets): make slow pet generation suite opt-in

The pet generation image-processing suite is deterministic but expensive enough
to blow the per-file CI timeout on Linux (140s), and it is not relevant to the
fast timeout PR's normal signal. Keep it available for manual validation, but do
not run it by default.

Set HERMES_RUN_SLOW_PET_TESTS=1 to enable the suite. The canonical test wrapper
now preserves that opt-in variable through its hermetic env.

Subject: [PATCH 161/244] fix(ui): share compact tool previews across clients

Move terminal/execute_code/read_file preview compaction into agent.display so CLI, gateway, and Ink TUI all inherit the same labels that desktop introduced in #52321.

The shared preview keeps raw args intact while trimming display-only shell plumbing (`cd`, pipe tails, banner/status echoes) and read_file line ranges. Desktop now prefers backend `context` for live rows and keeps its TypeScript fallback only for hydrated history.

Subject: [PATCH 162/244] feat(pets): remix a draft into a fresh round

Add a hover/focus "Remix" action on each completed draft card in the
generation grid. It re-runs generation with the chosen draft fed back in
as the reference image, keeping the same prompt and staying on step 2 so
the user can explore variations without starting over.

Because regenerating is slow and replaces the current drafts, the first
remix shows a one-time confirmation; the acknowledgement is persisted so
subsequent remixes fire immediately.

Subject: [PATCH 164/244] feat(setup): add _select_zai_endpoint helper for Z.AI
 endpoint picker
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Presents a curses-based picker (via _prompt_provider_choice) offering the
four official Z.AI endpoints — Global, China, Coding Plan Global, Coding
Plan China — plus a custom-proxy option. Sourced from ZAI_ENDPOINTS in
auth.py so it stays in sync with the probe list.

Not yet wired into the setup flow; that comes in the next commit.

Subject: [PATCH 165/244] feat(setup): wire Z.AI endpoint picker into
 _model_flow_api_key_provider

When provider_id == 'zai', replace the plain text Base URL input with
_select_zai_endpoint, which presents a curses picker offering Global,
China, Coding Plan Global, Coding Plan China, and custom proxy options.
Other API-key providers (MiniMax, DeepSeek, etc.) keep the text input.

Subject: [PATCH 166/244] test(setup): add ZAI endpoint picker tests, move
 base-URL tests to MiniMax

Z.AI now uses a curses picker instead of plain text input for base URL,
so the existing TestBaseUrlValidation tests (which used zai as their test
subject) are migrated to MiniMax, which still uses the text input path.

Add TestZaiEndpointPicker covering:
- Selecting each official endpoint (Global, China, Coding Plan Global,
  Coding Plan China) saves the correct base URL to config
- Custom proxy URL entry (valid + invalid rejection)
- Cancel keeps the existing base URL
- Current endpoint is the default choice in the picker
- Non-standard URL defaults to the Custom proxy option

- Remove dead `chosen_base or effective_base` fallback; _select_zai_endpoint
  always returns a non-empty base URL (returns current_base on cancel).
- Add .rstrip("/") to official-endpoint return for symmetry with custom-proxy
  path (both now return normalized URLs).
- Replace magic index 4 with len(ZAI_ENDPOINTS) in custom-proxy tests so they
  don't break if a 5th endpoint is added to ZAI_ENDPOINTS.

Subject: [PATCH 168/244] fix(auth): honor NOUS_INFERENCE_BASE_URL env override
 for Nous OAuth sessions (#52270)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The host-allowlist hardening (#30611) plus the refresh heal (#49735) left
the documented NOUS_INFERENCE_BASE_URL dev/staging escape hatch unreachable
for OAuth sessions, despite three code comments asserting it still works.

Root cause — resolution precedence in resolve_nous_runtime_credentials:

    inference_base_url = (
        _optional_base_url(state.get("inference_base_url"))  # stored — wins
        or os.getenv("NOUS_INFERENCE_BASE_URL")              # env — unreachable
        or DEFAULT_NOUS_INFERENCE_URL
    )

A staging OAuth login persists its inference_base_url, but the allowlist
rejects the staging host and the refresh heal rewrites the stored value to
the production default. The stored (now prod) value is then read BEFORE the
env var, so the override never takes effect — every request 401s against
prod or is pinned to prod, and setting the env var does nothing.

Fix: the user-set env override is the most-trusted source, so consult it
FIRST for the URL used to build the client / returned to callers — while
keeping the PERSISTED value the validated, network-provenance one (the
override is a runtime overlay, never written to auth.json, so unsetting it
cleanly reverts to prod). Applied at both chokepoints:

- resolve_nous_runtime_credentials (no-refresh read path AND refresh path)
- the nous_portal proxy adapter, which re-validates the resolver's returned
  base_url against the prod allowlist as defense-in-depth and would
  otherwise reject a legitimate staging override at the forward boundary.

New _nous_inference_env_override() / split of stored-vs-effective URL keep
the threat model intact: Portal-returned URLs are still allowlist-validated
at every network site, and the env path stays ungated (trusted OS user).

Also folds in the no-refresh read-path heal (supersedes the approach in
the open #50265): a poisoned stored staging host now heals to the prod
default on read even when no refresh fires.

Tests: TestEnvOverrideWins (env wins on read + refresh paths; override never
persisted; poisoned stored heals) and TestProxyAdapterEnvOverride. Verified
the 4 behavioral tests fail against pre-fix code and pass with the fix; full
inference-validation + nous-provider suites green (85 passed). E2E-validated
against a real temp HERMES_HOME exercising the real resolver + proxy adapter:
resolver→staging, persisted→prod, proxy→staging, unset→reverts to prod.

Subject: [PATCH 171/244] fix(learn): teach /learn the full CONTRIBUTING.md
 skill standards (#52372)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The /learn authoring prompt taught a subset of the HARDLINE skill rules,
and stated the <=60-char description rule without making the model enforce
it — so generated descriptions overshot (up to 202 chars), which the
60-char system-prompt skill index then silently truncates.

- description: add the index-truncation rationale, a count-and-trim
  self-check, and a good/bad length example so the model actually hits <=60.
- add platforms-gating rule (OS-bound primitives -> declare platforms:).
- add author-credits-human-first rule.
- round out the Hermes-tool framing with the full wrapped-tool mapping and
  references/templates layout.

Closes #52367.

Subject: [PATCH 174/244] fix(desktop): ad-hoc sign macOS self-update rebuilds

The desktop self-updater rebuilds and re-signs the .app on each user's own
machine (`hermes desktop --build-only` -> electron-builder `--dir`). With
CSC_IDENTITY_AUTO_DISCOVERY on (its default), electron-builder signs the
type=distribution, hardened-runtime bundle with whatever identity is in that
user's keychain -- typically a personal "Apple Development" cert -- which
stalls/fails the sign step (no Developer ID, no provisioning profile) or
clobbers the original notarized signature with an unusable one, tripping
Gatekeeper on every post-update launch.

Force ad-hoc signing for the local packaged rebuild instead: deterministic,
and exactly what _desktop_macos_relaunchable_fixup already finishes off.
No-op for source runs, off-macOS, when a real identity is configured
(CSC_LINK / APPLE_SIGNING_IDENTITY), or when the caller already pinned the flag.

Subject: [PATCH 175/244] fix(agent): close tool-call sequence on all interrupt
 aborts, not just finalize_turn
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

#48879 closed the tool-call sequence on interrupt inside finalize_turn so a
/stop after a tool no longer persists a `tool` tail that the next user message
turns into a `tool -> user` role-alternation violation (which strict providers
like Gemini/Claude react to by hallucinating a continuation and ignoring prior
context — what users see as "lost context after stop").

But the retry-wait, error-handling, and post-error retry-wait interrupt aborts
in conversation_loop return early and never reach finalize_turn, so they still
persisted and returned a raw `tool` tail. Interrupting during provider
backoff/rate-limiting (common under heavy work) hit exactly this path.

Extract the close into a shared close_interrupted_tool_sequence helper and apply
it at every interrupt abort (finalize_turn + the three early returns) so the
whole bug class is fixed, not just the one site.

Subject: [PATCH 176/244] fix(tui_gateway): queue mid-turn prompts instead of
 dropping them on a busy retry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A prompt sent while a turn was in flight got rejected with 4009 "session busy",
which pushed clients (the desktop app) into a deadline-bounded busy-retry. When
turn teardown outlived that deadline — e.g. the user hits stop while a slow,
non-interruptible tool (web_search, read_file, an MCP call) is mid-flight, since
the sequential executor only checks the interrupt flag between tools — the
resubmitted message was silently dropped: "it just doesn't listen".

Wire the previously-dead display.busy_input_mode config into prompt.submit:
instead of rejecting, apply the policy and queue the message to run as the next
turn (drained in run()'s tail, ahead of goal/notification follow-ups). Modes:
interrupt (default) interrupts the live turn so it winds down promptly then runs
the queued message; queue runs it after the current turn finishes; steer injects
it into the live turn when accepted, else queues. The queued slot pins the
sender's transport and losslessly merges a second arrival. No client deadline,
no dropped sends.

Subject: [PATCH 177/244] fix(terminal): improve sudo -S password delivery and
 cache invalidation

Pipe one password line per sudo invocation in compound commands so a correct
password is not rejected on the second `sudo` in `sudo a && sudo b`. Drop the
session cache when sudo returns Authentication failed, surface sudo_auth_failed
in the tool result, and add hints for interactive sessions.

 multi-sudo tip
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace _count_real_sudo_invocations (which called
_rewrite_real_sudo_invocations and discarded the rewritten string) with
a lightweight token scan that reuses the same tokeniser but skips string
building. Remove the agent-facing tip about nested sudo in heredocs —
the cache-cleared warning is enough.

Subject: [PATCH 180/244] fix(utils): unify YAML list indent across all config
 writers (#31999)

atomic_yaml_write used default yaml.dump which emits indentless
sequences (list items at column 0), while atomic_roundtrip_yaml_update
(ruamel.yaml) emits 2-space-indented sequences. Cross-path writes to
the same config.yaml toggled indentation on every save, eventually
producing a mixed-indent file that js-yaml rejects with 'bad indentation
of a mapping entry', silently dropping custom_providers and breaking
model switching.

Add IndentDumper SafeDumper subclass that forces indentless=False,
route atomic_yaml_write through it. Route tui_gateway._save_cfg and
the Telegram adapter's config writer through atomic_yaml_write so all
paths emit the same 2-indent layout.

Salvaged from #32034 by @xxxigm. Adapted to current main which already
has allow_unicode=True (from #51356) but was missing IndentDumper.

Closes #31999

Subject: [PATCH 181/244] fix(mcp): run OSV malware preflight off the event
 loop with a bounded timeout (#29184)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

During stdio MCP server startup, _run_stdio (an async method) called the
synchronous check_package_for_malware() inline. That makes a blocking
urllib HTTPS POST to api.osv.dev whose own timeout doesn't reliably cover a
stalled SSL handshake, so an intermittent network issue froze the entire
asyncio event loop for up to ~120s — blowing past the TUI/gateway's 15s
startup budget and showing "gateway startup timeout".

Run the check via asyncio.to_thread (off the loop) AND bound it with
asyncio.wait_for(timeout=_OSV_MALWARE_CHECK_TIMEOUT_S=12s). The malware check
is fail-open, so on timeout we log and proceed rather than blocking startup.

Salvaged from #29190 by @qdaszx (re-applied on current main — the call site
moved since the PR was opened), combining the to_thread approach also proposed
in #29192 by @ygd58. Two load-bearing tests: event-loop-not-blocked-during-
check and timeout-fails-open — both mutation-verified to fail against the old
inline blocking call.

Closes #29184.

Subject: [PATCH 182/244] fix(tools): defensive type coercion in todo_tool for
 malformed LLM input (#14185)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

todo_tool crashed with `AttributeError: 'str' object has no attribute 'get'`
when the LLM emitted the `todos` param as a JSON-encoded string instead of an
array, or as a list containing non-dict items (observed intermittently on
Claude 4.5/4.6/4.7, and after a prior tool-call rejection where the model
"self-corrects" by wrapping the list in json.dumps).

Three additive guards, no behavior change for well-formed input:
- todo_tool(): if `todos` is a str, json.loads it; reject unparseable strings
  and non-list values with a clear tool_error instead of crashing downstream.
- _validate(): non-dict items return a {id:"?", content:"(invalid item)"}
  placeholder rather than calling .get() on a str/int/None.
- _dedupe_by_id(): non-dict items get a synthetic key so _validate handles them.

Salvaged from #14785 by @Tranquil-Flow (authorship preserved via cherry-pick).
Comprehensive tests: JSON-string coercion (parse / unparseable / non-list /
non-string), non-dict list items (str/None/int/mixed), and a well-formed-
unchanged regression class — both guards mutation-verified to fail without them.

Closes #14185. Supersedes #14187, #22505, #14350 (same fix, less/no test
coverage) and #16952 (bundled unrelated scope-creep).

Subject: [PATCH 183/244] fix(gateway): dedupe user turns on transient failure
 (#47237)

When the gateway persists a user message after a transient provider
failure (429/timeout/auth error), subsequent retries of the same
Telegram message could stack duplicate user turns in the transcript,
causing the agent to fall behind by 1-2 messages.

Add has_platform_message_id() to SessionDB (using the existing
idx_messages_platform_msg_id partial index) and a SessionStore wrapper.
The gateway's transient-failure path checks this before
append_to_transcript -- if the platform_message_id is already
persisted, the duplicate write is skipped.

Salvaged from #47869 by @davidgut1982. Adapted to current main which
has additional append sites and an existing content-based dedupe in
the exception handler path.

Closes #47237

Subject: [PATCH 184/244] perf(desktop): make session switching fast under load
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Switching sessions in the desktop app could freeze the whole UI for
several seconds on heavy, tool-rich chats. Root causes and fixes:

- Cold `session.resume` built the AIAgent (MCP discovery, prompt/skill
  build) *before* returning, and the desktop awaits that RPC before it
  paints — so the entire switch blocked on the build. Add an opt-in
  `defer_build` resume path (the contract `session.create` already uses):
  return the full display transcript immediately, register an upgradable
  live session, and pre-warm the agent on a short timer. The persisted
  runtime identity (model/provider/base_url/api_mode/reasoning/tier) is
  restored on the deferred build so it can't drop the provider.

- Nothing bounded how many in-memory agents accumulate; a user who
  reconnects often piled up detached sessions for the full 6h TTL. Add a
  soft LRU cap (`max_live_sessions`, default 16) that evicts the
  least-recently-active DETACHED sessions (no live client) — never a
  running, awaiting-input, mid-build, or live-transport one. Reopening
  re-resumes from disk.

- On the prefetch-hit cold-resume path, skip rebuilding a throwaway
  merged-message array (and its 1000-entry Map) when the prefetch already
  painted the exact transcript; the downstream sameMessageList guard
  already drops the publish, so it was pure main-thread cost.

The desktop opts into `defer_build` for every non-watch cold resume; the
eager path stays for CLI/TUI and existing callers.

Subject: [PATCH 185/244] perf(desktop): make deferred resume the default, not
 an opt-in flag
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Per review: gating the faster path behind a `defer_build` flag that the
only caller always sends is pointless. Flip it — `session.resume` now
defers the agent build by default for every caller (desktop + Ink TUI);
a caller that needs the agent built synchronously passes `eager_build:
true` (used by the build-race test). The desktop no longer sends a flag.

While verifying the flip, fixed two real parity gaps the deferred path
had vs the old eager (`_init_session`) path:

- `_enable_gateway_prompts()` was never called on a deferred resume, so
  approvals/clarify wouldn't route through the gateway prompt callbacks.
- `_start_agent_build` never wired `background_review_callback` /
  `memory_notifications`, so a deferred-built session's self-improvement
  "💾 …" summary leaked to stdout instead of rendering in-transcript.
  Wiring it there also fixes it for `session.create` sessions, which
  build through the same path.

ACP is unaffected (it uses its own session_manager, not this RPC); the
Ink TUI already consumes the same lazy `info` shape from session.create
and upgrades on the later `session.info` event.

Subject: [PATCH 186/244] refactor(tui_gateway): DRY the deferred-session paths

Collapse the duplicated cold-resume / lazy-watch / create scaffolding into
shared helpers: _deferred_session_record (the live-session dict minus the
agent), _lazy_resume_info (the not-yet-built session.info), _claim_or_reuse_live
(lock + double-checked register-or-reuse), and _schedule_agent_build (the
pre-warm timer). Net -12 lines, three copies of the ~30-key session dict and
the lazy-info block down to one each. No behavior change.

Subject: [PATCH 187/244] fix(desktop): show statusbar item tooltips on hover
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Statusbar items declared a 'title' string (e.g. YOLO, gateway health,
agents, cron, version, context usage) that was populated by
use-statusbar-items.tsx but never forwarded to the rendered DOM in
StatusbarControls — so every statusbar button/menu/text/link had no
hover hint.

Wrap the four render branches (menu trigger, text, link, action) in
the existing 'Tip' component from components/ui/tooltip.tsx. Tip is
self-contained (carries its own Provider), instant (delayDuration=0),
themed (bg-foreground/text-background, auto-inverts per theme), and
already in use elsewhere in the desktop shell. Renders the child
untouched when label is falsy, so items without a title stay
zero-cost.

Subject: [PATCH 188/244] test(tui_gateway): pin synchronous-build resume tests
 to eager_build
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

These three assert the eager build contract — stored runtime overrides /
profile db reach _make_agent synchronously, and the agent binds to the
compression tip. Under deferred-by-default the build runs off-thread, so
they raced the timer (green in CI, flaky locally). Pin them to
eager_build; deferred coverage lives in the protocol tests.

Subject: [PATCH 189/244] fix(gateway): pass session_db to compress temp agents
 so persistence works
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Manual /compress and session hygiene auto-compress both create temporary
AIAgent instances to run compression. These agents were created without
a session_db, so compress_context computed the compressed messages in
memory, rotated the session ID, and reported success — but never wrote
to the database. The next user message reloaded the original full
transcript, making compression appear to do nothing.

Fix: pass session_db=self.session_store._db to both temp agents so the
session rotation is properly persisted. Also set _end_session_on_close
on the /compress temp agent (already done in hygiene path) to prevent
cleanup from ending the newly rotated session.

Subject: [PATCH 190/244] fix: use self._session_db directly + add regression
 test

- Replace getattr(self.session_store, '_db', None) with self._session_db
  (the GatewayRunner's own SessionDB, consistent with existing usage in
  slash_commands.py L240/L499).
- Remove verbose comment referencing a branch name as an issue number.
- Update stale comment in run.py that said 'today it has no session_db'.
- Add regression test verifying session_db is passed and rotated session
  is persisted (adapted from #51624 by @LeonSGP43).
- Add _session_db=None to _make_runner fixtures in test_compress_command,

Subject: [PATCH 195/244] fix(learn): name distilled skills as author Hermes,
 not the host OS user (#52388)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

/learn told the agent to fill the skill `author` field, and the system
prompt environment probe surfaces the OS login name (user=$(whoami) in
prompt_builder.py), so the model wrote the host username into published
SKILL.md frontmatter — a privacy leak the user never opted into, and
inconsistent run to run as the most-salient identity changed.

The /learn authoring prompt now sets `author` to the literal value
`Hermes` and explicitly forbids deriving it from the host environment
(OS/login user, git config, or any probeable identity). The skill names
itself as the tool that wrote it.

Closes #52368.

Subject: [PATCH 196/244] fix: persist non-NULL system prompt on fresh turn
 setup (#45499) (#52616)

build_turn_context() created the DB session row via _ensure_db_session()
before the system prompt was restored/built, so a fresh API/gateway agent
carrying client-managed history inserted a row with system_prompt=NULL. That
tripped the misleading 'stored system prompt is null; rebuilding from scratch
... investigate the previous turn's write path' warning and a guaranteed
first-turn prefix cache miss. Move row creation to after _cached_system_prompt
is populated.

Verified live (OpenRouter + claude-sonnet-4.5): persistent-agent turns show
cache_read jumping to the full prefix on turn 2+ (write 24411 -> read 24411),
and the persisted system_prompt is non-NULL so fresh-agent restore keeps the
prefix cache warm.

Tests: turn-context ordering regression asserting _ensure_db_session runs
after _cached_system_prompt is populated.

Subject: [PATCH 197/244] fix(gateway): read compaction result flag not config
 flag in hygiene guard (#50098)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Salvage of #50098 by @srojk34, cherry-picked onto current main.

The hygiene auto-compress guard and the /compress slash command both read
compression_in_place (config flag — is in-place mode enabled?) instead of
_last_compaction_in_place (result flag — did in-place compaction actually
succeed?). Both agents are built without a session_db, so archive_and_compact
always fails silently and _last_compaction_in_place stays False. Reading the
config flag makes the guard think in-place succeeded, triggering
rewrite_transcript() which replaces the original messages with only the
compressed summary — permanent data loss.

Subject: [PATCH 198/244] feat(compression): flip in_place default to True
 (#38763) [2/2]
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In-place compaction (single durable session id, non-destructive soft-archive)
becomes the default. Rotation is now the opt-out fallback via
compression.in_place: false.

Prerequisite: #50098 (hygiene guard reads result flag not config flag) merged
first — without it, flipping the default causes permanent transcript loss on
gateway hygiene-compress and /compress when no session_db is available.

Blast radius (empirically measured on current main): 7 rotation-asserting
tests broke and are pinned to in_place=False in the companion test commit:
- tests/agent/test_compression_concurrent_fork.py (2)
- tests/agent/test_compression_logging_session_context.py (1)
- tests/agent/test_compression_rotation_state.py (1)
- tests/run_agent/test_compression_boundary_hook.py (2 _make_agent helpers)
- tests/gateway/test_compression_concurrent_sessions.py (2)
Rotation stays as a working fallback and deserves continued coverage.

Subject: [PATCH 199/244] test(compression): pin rotation-fallback tests to
 in_place=False ahead of default flip
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

These 7 test sites assert rotation behavior (fork, child sessions, lock
contention, logging session-context follows id rotation, boundary hooks fire
on rotation). Pin each builder to in_place=False explicitly so they keep
exercising the retained rotation fallback regardless of the global default
(flipped to True in #38763). Rotation stays a working opt-out fallback and
deserves continued coverage — these are NOT deleted.

Pinned sites:
- test_compression_concurrent_fork._build_agent_with_db
- test_compression_logging_session_context._build_agent_with_db
- test_compression_rotation_state._build_agent_with_db
- test_compression_boundary_hook._make_agent (2 helpers: CompressionBoundaryHook + SessionCompressEvent)
- test_compression_concurrent_sessions._build_agent_with_db

Subject: [PATCH 201/244] fix(auxiliary): treat 403 subscription and
 session-usage-limit errors as payment errors for fallback

Ollama Cloud (and similar) return 403 with bodies like "this model requires
a subscription, upgrade for access" or "you have reached your session usage
limit, upgrade for higher limits". These are capacity/billing conditions
semantically identical to credit exhaustion, but _is_payment_error() did not
recognize them (403 missing from the status set; keywords missing), so the
configured fallback_chain was never tried and compression failed outright.

Adds 403 to the status set and the subscription/session-usage keywords.

Subject: [PATCH 202/244] fix: include rate-limit in auxiliary capacity-error
 fallback gate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rate-limit (429) errors on explicit-provider auxiliary tasks were
silently failing instead of triggering the fallback chain. The
is_capacity_error gate only checked payment and connection errors,
excluding rate limits — so when a configured provider like
openai-codex hit its rate limit, auxiliary tasks (kanban_decomposer,
vision, web_extract, approval, etc.) had zero resilience.

Add _is_rate_limit_error() to is_capacity_error at both call sites
(sync and async paths) so rate limits trigger fallback regardless
of whether the provider was auto-detected or explicitly configured.

Fixes #52228

Subject: [PATCH 203/244] fix(auxiliary): honor fallback chain when compression
 provider auth is unavailable

When an explicit aux provider cannot build a client before any request is
sent (missing raw env key, exhausted/unavailable OAuth or credential-pool
auth, resolver returning (None, None)), call_llm raised a misleading
"no API key was found" error and bypassed the configured fallback_chain
entirely. A provider authenticated through Hermes auth / the credential
pool (e.g. ollama-cloud) whose pool entry is exhausted hit this path, so
compression failed instead of routing to the configured fallback.

Adds _try_configured_fallback_for_unavailable_client() and wires it into
both sync and async call_llm before the raise, and into the startup
compression feasibility check.

Subject: [PATCH 204/244] fix(auxiliary): screen fallback chain by context
 window for compression (#52392)

The runtime auxiliary fallback chain (_try_configured_fallback_chain and
_try_main_fallback_chain) returned the first reachable candidate without
checking whether the candidate's context window was large enough for the
task. For task='compression' this meant a reachable but undersized
fallback (e.g. 32K) could be selected and then fail, even when a later
larger-context fallback was available.

This adds two small helpers:

  _task_minimum_context_length(task)
      Returns MINIMUM_CONTEXT_LENGTH (64K) for compression, None for
      other tasks (vision, web_extract, etc.).

  _candidate_context_window(provider, model, ...)
      Thin wrapper around get_model_context_length that returns None on
      probe failure so unknown/custom endpoints pass through unchanged
      (preserves the existing fallback surface).

Both fallback loops now skip reachable candidates whose resolved context
is below the task minimum and continue iterating. The success path
(first viable candidate wins) is unchanged. Return shape and ordering
for healthy candidates are preserved.

Six regression tests cover:
  L2 configured chain skips too-small candidate
  L2 chain continues after skipping, returns last viable
  L3 main chain skips too-small candidate
  L4 unknown-context candidate passes through
  L5 non-compression task is not filtered
  L6 minimum constant matches MINIMUM_CONTEXT_LENGTH (64K)

3/6 fail on upstream/main without the production change (verified); all
6 pass with the fix. Full test_auxiliary_client.py suite (231 tests)
and related compression tests (130 tests) remain green.

Subject: [PATCH 205/244] fix(auxiliary): fall back when a route can't run the
 model at all (400 capability mismatch)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The salvaged context-window screen (#52392) skips fallback candidates that
are too small, and the rate-limit/403 fixes skip candidates that are at
capacity. A third hard failure remained uncovered: a fallback that builds a
client fine but returns a 400 because it structurally cannot run the model.
The canonical case is a configured openai-codex / ChatGPT-account fallback
asked to compress a glm-5.2 conversation:

    400 - {'detail': "The 'glm-5.2' model is not supported when using
    Codex with a ChatGPT account."}

This is a request-validation error, so should_fallback was False and the
explicit-provider gate blocked it — the auxiliary task (compression) aborted
every turn, dropping middle turns without a summary and churning the session,
which is exactly what destroys the prompt cache.

Adds _is_model_incompatible_error() (400 + capability phrasing, excluding
not-found and billing 400s which the sibling predicates own) and treats it as
a fallback-worthy capacity error in both sync and async call_llm, so the chain
skips the incapable route and continues to the next viable candidate.

Subject: [PATCH 207/244] fix(telegram): auto-rich pipe tables and topic
 routing for sendRichMessage

Pipe-only markdown tables now use sendRichMessage even when rich_messages
is off, and resumed DM-topic sends route via direct_messages_topic_id
without requiring a reply anchor. Rich finalize edits forward topic kwargs.

Subject: [PATCH 209/244] fix(cron): restore [SILENT] silence + suppress
 empty-turn explainer on Telegram
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Scheduled jobs delivering to Telegram/etc. started posting a literal
'⚠️ No reply: the model returned empty content…' message instead of
staying silent. Two interacting causes:

1. The turn-completion explainer (#34452) replaces an empty model turn
   with a user-facing '⚠️ No reply…' string. In a cron context that is
   not a silence marker, so the scheduler delivered it — a regression
   from the previously-silent empty turn. run_job now detects the
   explainer text deterministically (via the same formatter that
   produced it) for abnormal-empty turn_exit_reasons and strips it to
   empty, so the existing empty-response suppression + soft-fail guard
   apply. The explainer is unchanged on CLI/gateway.

2. The cron suppression used a loose 'SILENT_MARKER in ...upper()'
   substring check. It leaked bracketless near-markers the model emits
   ('SILENT', 'NO_REPLY', 'NO REPLY' — #51438, #46917) and wrongly
   swallowed a real report that merely quoted '[SILENT]' mid-sentence.
   Replaced with _is_cron_silence_response(): suppresses a canonical
   token as the whole response, its own first/last line, or the
   documented bracketed '[SILENT] <note>' prefix — while a token buried
   mid-sentence in a genuine report is delivered. Preserves the
   intentional cron trailing/prefix tolerance (existing tests unchanged).

Tests: bracketless-variant suppression, mid-sentence-quote delivery,
direct matcher contract, and explainer-strip + defensive real-report
delivery.

Subject: [PATCH 210/244] feat(moa): expose MoA presets as selectable virtual
 models (#46081)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* feat(moa): expose MoA presets as selectable virtual models

Reconstructed onto current main (PR #46081's base had diverged with no common
ancestor, marking the PR dirty so CI never dispatched). MoA is now a virtual
provider: each named preset is a selectable model under provider 'moa', and the
preset's aggregator is the acting model that answers and calls tools.

Reference models fan out in parallel via a bounded ThreadPoolExecutor (the same
batch pattern delegate_task uses) — all references dispatched at once, collected
when every one finishes, then handed to the aggregator. Output order is
preserved, failures and the MoA-recursion guard stay isolated per reference.

- Removed the old mixture_of_agents model tool and moa toolset.
- Added moa as a virtual provider in the provider/model inventory.
- /moa is shortcut behavior over model selection (default preset / named preset
  / one-shot prompt).
- Dashboard + Desktop manage named presets; presets appear in model pickers.
- Parallel reference fan-out in agent/moa_loop.py with regression test.

* fix(moa): thread moa_config through _run_agent to _run_agent_inner

The reconstructed gateway MoA wiring declared moa_config on _run_agent (the
profile-scoping wrapper) and used it inside _run_agent_inner, but the wrapper
never forwarded it — _run_agent_inner had no such parameter, so the runtime hit
NameError: name 'moa_config' is not defined on the compression-failure session
sync path. Add moa_config to _run_agent_inner's signature and forward it from
both wrapper call sites (multiplex and non-multiplex). Caught by
tests/gateway/test_compression_failure_session_sync.py on CI shard test(4).

* fix(moa): classify moa as a virtual provider in the catalog

The moa virtual provider has no PROVIDER_REGISTRY/ProviderProfile entry, so
provider_catalog() fell through to the default auth_type="api_key" with no
env vars — tripping two catalog invariants:
  - test_provider_catalog: api_key providers must expose a credential env var
  - test_provider_parity: every hermes-model provider must be desktop-configurable

moa already declares auth_type="virtual" in HERMES_OVERLAYS; consult that
overlay as an auth_type fallback so the catalog reports moa as virtual (no real
credential, no network endpoint). Exempt virtual providers from the desktop
parity union check the same way 'custom' is exempt — derived from the catalog,
not a hardcoded slug, so future virtual providers are covered too.

-Mixture-of-Agents Tool Module
-
-This module implements the Mixture-of-Agents (MoA) methodology that leverages
-the collective strengths of multiple LLMs through a layered architecture to
-achieve state-of-the-art performance on complex reasoning tasks.
-
-Based on the research paper: "Mixture-of-Agents Enhances Large Language Model Capabilities"
-by Junlin Wang et al. (arXiv:2406.04692v1)
-
-Key Features:
-- Multi-layer LLM collaboration for enhanced reasoning
-- Parallel processing of reference models for efficiency
-- Intelligent aggregation and synthesis of diverse responses
-- Specialized for extremely difficult problems requiring intense reasoning
-- Optimized for coding, mathematics, and complex analytical tasks
-
-Available Tool:
-- mixture_of_agents_tool: Process complex queries using multiple frontier models
-
-Architecture:
-1. Reference models generate diverse initial responses in parallel
-2. Aggregator model synthesizes responses into a high-quality output
-3. Multiple layers can be used for iterative refinement (future enhancement)
-
-Models Used (via OpenRouter):
-- Reference Models: claude-opus-4.6, gemini-3-pro-preview, gpt-5.4-pro, deepseek-v3.2
-- Aggregator Model: claude-opus-4.6 (highest capability for synthesis)
-
-Configuration:
-    To customize the MoA setup, modify the configuration constants at the top of this file:
-    - REFERENCE_MODELS: List of models for generating diverse initial responses
-    - AGGREGATOR_MODEL: Model used to synthesize the final response
-    - REFERENCE_TEMPERATURE/AGGREGATOR_TEMPERATURE: Sampling temperatures
-    - MIN_SUCCESSFUL_REFERENCES: Minimum successful models needed to proceed
-
-Usage:
-    from mixture_of_agents_tool import mixture_of_agents_tool
-    import asyncio
-    
-    # Process a complex query
-    result = await mixture_of_agents_tool(
-        user_prompt="Solve this complex mathematical proof..."

+description: "Create named MoA presets that appear as selectable models under the Mixture of Agents provider"
+---
+
+# Mixture of Agents
+
+Mixture of Agents is a virtual model provider. Each named MoA preset appears as a selectable model under the `moa` provider.
+
+When you select a MoA preset, the preset's aggregator is the acting model. It is the model that writes the assistant response and emits tool calls. Reference models run first and provide analysis for the aggregator to use.
+
+Use MoA when a hard task benefits from multiple model perspectives but still needs Hermes' normal agent loop: tool calls, follow-up iterations, interrupts, transcript persistence, and the same session context as any other message.
+
+## Select a MoA preset as your model
+
+You can select a preset through the normal model picker surfaces:
+
+```bash
+/model default --provider moa
+/model review --provider moa
+```
+
+The Dashboard, TUI, and Desktop model pickers also show a `Mixture of Agents` provider row. Its models are your configured preset names.
+
+## Slash command shortcut
+
+`/moa` is convenience sugar over model selection:
+
+```bash
+/moa
+```
+
+Switches the current session to the default MoA preset.
+
+```bash
+/moa review
+```
+
+If `review` exactly matches a preset name, switches the current session to provider `moa`, model `review`.
+
+```bash
+/moa design and implement a migration plan for this flaky test cluster
+```
+
+If the text does not exactly match a preset name, Hermes treats it as a one-shot prompt. It temporarily switches to the default MoA preset for that turn, sends the prompt, then restores the previous model afterward.
+
+Preset matching is exact on purpose. Hermes does not fuzzy-match preset names, so normal prompts cannot accidentally become model switches.
+
+## How it works in the agent loop
+
+For each main model call when provider `moa` is selected, Hermes:
+
+1. resolves the selected preset by name;
+2. runs the configured reference models without tool schemas (they receive only the conversation's user/assistant text — not the Hermes system prompt or tool-call transcript — so reference calls stay cheap and avoid strict-provider rejections);
+3. appends the reference outputs as private context for the aggregator;
+4. calls the configured aggregator with the normal Hermes tool schema;
+5. treats the aggregator response as the real model response;
+6. if the aggregator calls tools, Hermes executes those tools normally;
+7. on the next model iteration, the same MoA process runs again over the updated conversation, including tool results.
+
+Because MoA is selected through the normal model system, it composes automatically with `/goal`, gateway sessions, TUI sessions, and Desktop chat.
+
+## Configure presets
+
+You can configure named MoA presets from:
+
+- Dashboard → Models → Model Settings → Mixture of Agents
+- Desktop app → Settings → Model → Mixture of Agents
+- `hermes moa configure [name]`
+- `config.yaml`
+
+The config stores explicit provider/model pairs, so you can mix providers and use multiple models from the same provider:
+
+```yaml
+moa:
+  default_preset: default
+  presets:
+    default:
+      reference_models:
+        - provider: openai-codex
+          model: gpt-5.5
+        - provider: openrouter
+          model: deepseek/deepseek-v4-pro
+      aggregator:
+        provider: openrouter
+        model: anthropic/claude-opus-4.8
+      reference_temperature: 0.6
+      aggregator_temperature: 0.4
+      max_tokens: 4096
+      enabled: true
+```
+
+Default preset:
+
+- reference: `openai-codex:gpt-5.5`
+- reference: `openrouter:deepseek/deepseek-v4-pro`
+- aggregator / acting model: `openrouter:anthropic/claude-opus-4.8`
+
+## Terminal preset management
+
+```bash
+hermes moa list
+hermes moa configure              # update the default preset
+hermes moa configure review       # create or update a named preset
+hermes moa delete review
+```
+
+## Notes
+
+- MoA is no longer listed under `hermes tools`; there is no `moa` toolset to enable.
+- Setting `enabled: false` on a preset disables the reference fan-out for that preset: the aggregator acts alone, exactly as if you selected it as a plain model. This is the per-preset off switch surfaced in the dashboard and desktop settings.
+- A preset's aggregator cannot be another MoA preset. Recursive MoA trees are intentionally blocked.
+- Credential failures on one reference model do not abort the turn. Hermes includes the failure in the reference context and continues with whatever models returned.
+- MoA increases model-call count. A single model iteration can involve multiple reference calls plus the aggregator call.

Subject: [PATCH 211/244] fix(desktop): reject cross-wired runtime-id cache on
 session resume

resumeSession's warm-cache fast-path trusted the
storedSessionId -> runtimeId -> ClientSessionState mapping without
checking the cached state still BELONGS to the session being resumed.
A pooled profile backend that gets idle-reaped and respawned
(pruneSecondaryGateways) re-mints runtime ids, so a recycled id can
resolve to a live-but-DIFFERENT session's cache entry. The only
existing guard was a session.usage 404 -- that catches a fully-dead
runtime id, but a recycled id still 200s, so the fast-path happily
painted the wrong transcript under the current route (open chat A,
chat B loads).

Fold the belongs-to check into a single takeWarmCache() helper used at
BOTH cache reads -- the early transcript-keep decision and the fast-path
itself -- so a cross-wired entry can't even briefly flash a stale
transcript before the full resume repaints. On a mismatch the helper
purges both stale map entries and reports a miss, falling through to a
full resume that rebinds a correct runtime id. The full-resume path
already guards its final paint with isCurrentResume(), so only the
cached fast-path was missing the belongs-to check.

Pre-existing bug from the initial desktop app (#20059); not introduced
by the session-switch perf work (#49807), which left these lines
untouched.

Tests: two cases in use-session-actions.test.tsx driven through a
harness that owns the two cache maps -- a cross-wired mapping is
rejected + purged (the bug), and a correctly-wired cache still serves
from memory with no needless refetch (no perf regression).

Supersedes #50464 by @professorpalmer, reimplemented to also guard the
early transcript-keep read (whole-class fix, not just the fast-path).

Subject: [PATCH 212/244] fix(desktop): recover the root error boundary from
 transient render races

A stale-index render race in assistant-ui (a just-shrunk thread rendered
at an old message index during a session switch / teardown) throws
errors like "tapClientLookup: Index N out of bounds", "Cannot read
properties of undefined (reading 'type')", or "Tried to unmount a fiber
that is already unmounted". These bubble to the root ErrorBoundary and
latch the WHOLE desktop app on the "Reload window" fallback even though
the next render against fresh state would be fine.

Teach the root boundary to treat that small set of known-transient
renderer errors as recoverable: log them and schedule a next-tick
reset() so React re-renders against current state instead of stranding
the user on the fallback.

Auto-recovery is BOUNDED -- at most MAX_RECOVERIES (3) attempts within a
5s window -- so a genuinely persistent error can't spin the boundary in
a reset -> throw -> reset loop; after the budget is spent the fallback
is left up for the user. Manual retry (the button) resets the budget.
Only the root boundary auto-recovers; scoped boundaries keep their own
fallbacks, and unrecognized errors are never swallowed.

Tests: transient race recovers (fallback never sticks), a persistent
recoverable error stops at the cap and surfaces the fallback (proving
the loop is bounded), and neither a non-root boundary nor an
unrecognized root error auto-recovers.

Closes #41693. Supersedes #41787 by @izumi0uu, reimplemented with a
bounded recovery budget so a non-transient error can't loop forever.

+A Project is a human-named workspace spanning one or more folders, with one

+convention. State lives in the per-profile ``$HERMES_HOME/projects.db`` store

+"""Per-profile first-class Project store.
+
+A **Project** is a human-named, multi-folder workspace. Unlike the desktop's
+old inferred "workspaces" (derived from each session's ``cwd`` + a git probe)
+and unlike kanban's self-generated worktrees, a Project is an explicit,
+persisted entity the user creates and names. It anchors:
+
+- **Desktop session grouping** — a session belongs to a project when its
+  ``cwd`` lives under one of the project's folders (longest-prefix match).
+- **Kanban task worktrees** — a task linked to a project creates its worktree
+  under the project's primary repo with a deterministic branch name, instead
+  of the random ``wt/<task-id>`` fallback.
+
+Scope: **per-profile**, stored at ``$HERMES_HOME/projects.db`` (resolved via
+``get_hermes_home()``), mirroring sessions / config / cron. This deliberately
+differs from kanban, whose board DB is root-anchored and shared across
+profiles. A Project may *bind* a kanban board (``board_slug``) so the two
+systems agree on the repo + branch convention without merging their stores.
+
+The schema is intentionally small and additive: column additions go through

+"""Git working-tree probing for the gateway: run git, resolve repo roots, fold
+linked worktrees under their common root.
+
+Probing runs where the gateway runs, so it resolves repos for both local and
+remote backends (unlike the desktop's electron probe, which only sees the local
+fs). Resolved roots are cached with a thread-safe, single-flight cache: the
+gateway's long handlers run on worker threads, so concurrent identical probes
+(e.g. two overlapping project-tree builds) share one `git` invocation instead of
+racing an unguarded dict.
+
+Positive results are cached for the process lifetime; negative results (a cwd
+that isn't a git repo, or a deleted/nonexistent dir) are cached only for a short
+TTL (`_NEG_TTL`). Caching negatives matters a lot for the desktop Projects tree:
+``project_tree.build_tree`` resolves a cwd once *per session* (not per distinct
+cwd), so a power user with hundreds of sessions in non-git/deleted dirs would
+otherwise re-spawn ``git`` hundreds of times on *every* sidebar open — the cause
+of the multi-second "Projects" load. The TTL keeps a not-yet-repo cwd
+re-probable (we `git init` a new project's folder on its first worktree, and a
+frozen "" would mislabel its main lane by the dir basename) — it just stops the
+same "not a repo" answer from being re-derived dozens of times within one build
+and across rapid re-opens. `invalidate()` drops everything after a known
+mutation.

+"""Authoritative project -> repo -> lane -> session tree builder.
+
+This is the single source of truth for how the desktop sidebar groups sessions
+into projects, repos, and lanes. It is pure (all git resolution is injected via
+``resolve``) so it can be unit-tested with fixtures and reused by the gateway's
+``projects.tree`` / ``projects.project_sessions`` RPCs.
+
+It deliberately mirrors the desktop's former client-side grouping (the old
+``workspace-groups.ts``) so the emitted ids and lane keys stay byte-compatible
+with the renderer's persisted state (pins, manual ordering, dismissal), which
+all key off these exact strings:

+  - repo node id ................. the repo root path
+  - main branch lane id .......... ``<repoRoot>::branch::<branch>`` (or ``::branch::``)
+  - kanban bucket lane id ........ ``<repoRoot>::kanban``
+  - linked worktree lane id ...... the worktree path
+
+The one correctness upgrade over the client version: linked worktrees are folded
+under their MAIN repo via a git common-dir probe (injected as ``resolve``),
+instead of being treated as separate repos (``git rev-parse --show-toplevel``
+returns the worktree's own root, which is why the client double-counted them).

+"""Project tools — the agent's INTENTIONAL handle on first-class Projects.
+
+Projects (per-profile ``projects.db``) are the named workspaces the desktop
+sidebar groups sessions into. Creating / switching a project is a deliberate act
+expressed as explicit tools — never a side effect of a terminal ``cd``.
+
+Exposed only on GUI sessions: the tools live in the `project` toolset (kept off
+``_HERMES_CORE_TOOLS``) which the desktop/TUI gateway folds into its resolved
+toolsets, so no CLI/messaging/cron schema carries them. The GUI also wires
+``set_project_workspace_callback`` so a create/switch re-anchors the live
+session's cwd and the sidebar follows the move; the DB write is the durable part.

 Design notes
 ------------
 * ``schtasks /Create /SC ONLOGON /RL LIMITED`` means the task runs at the
-  CURRENT USER's next logon without any elevation prompt. We also
-  ``schtasks /Run`` immediately after install so the gateway starts right
-  away without waiting for the next logon.
-* We write two files: a shared ``gateway.cmd`` wrapper script (cwd + env + the
-  actual ``python -m hermes_cli.main gateway run --replace`` invocation) and
-  EITHER a schtasks entry pointing at it OR a Startup-folder ``.cmd`` that
-  spawns it detached.
+  CURRENT USER's next logon without any elevation prompt. Manual starts and
+  install ``--start-now`` use the direct detached ``pythonw`` launcher instead
+  of ``schtasks /Run`` so start/restart behavior is consistent.
+* We write a shared ``gateway.cmd`` wrapper plus a console-less ``gateway.vbs``
+  launcher. Scheduled Task and Startup-folder persistence both route through
+  VBS/wscript; immediate manual starts route through direct ``subprocess`` spawn.
 * Status = merge of "is the schtasks entry registered?" + "is the startup
-  .cmd present?" + "is there a gateway process running?" so the status
+  login item present?" + "is there a gateway process running?" so the status
   command keeps working regardless of which install path was taken.
 * Quoting is tricky: schtasks parses ``/TR`` itself and cmd.exe parses the
   generated ``gateway.cmd``. Those are DIFFERENT parsers. We keep two

COALESCE(column, ?) in update_token_counts(), making them write-once.
When a user switches models mid-session via /model, the runtime (agent.provider,
agent.base_url) updates correctly, but the session row never reflects the new
provider. This causes the dashboard Models page to display a stale provider
badge and misattributes token usage / cost analytics.

Fix: add update_session_billing_route() that unconditionally sets
billing_provider, billing_base_url, and billing_mode (no COALESCE), and call
it from switch_model() in agent_runtime_helpers.py after the swap succeeds.

This follows the same pattern as update_session_model() which already
unconditionally updates the model column (added for the identical COALESCE
problem on the model field).

Closes #48248

Subject: [PATCH 234/244] test(hermes_state): cover
 update_session_billing_route overwrite + prompt null

Regression for the salvaged #48254 fix: billing route is first-writer-wins
via update_token_counts (COALESCE), so a mid-session provider switch left
the dashboard attributing cost to the original provider. Asserts the new
update_session_billing_route() overwrites unconditionally, nulls system_prompt
so the next turn rebuilds Model:/Provider:, and preserves billing_mode when
omitted (COALESCE on None).

Subject: [PATCH 236/244] fix: stop reporting cache-hit rate and cost across
 all UI surfaces (#52717)

* fix: stop reporting cache-hit rate and cost across all UI surfaces

Cost estimates and cache read/write token reporting are unreliable on
providers that don't surface cached_tokens (e.g. ollama-cloud, which doesn't
implement prompt_tokens_details.cached_tokens), producing misleading
near-zero 'cache hit' readouts and cost figures. Remove cost + cache-hit
reporting from every user-facing surface; keep input/output/total token
counts (provider-agnostic and accurate) and the Nous account billing UI
(real account money, separate from per-conversation estimates).

Surfaces:
- CLI /usage + model-info: drop cost lines + cache read/write token lines
- Gateway /usage + /model: drop cost + cache lines
- tui_gateway/server.py: stop emitting cost_usd / cache_read in usage and
  subagent.complete payloads
- TUI (Ink): drop cost from status bar (+ showCost plumbing), /usage panel,
  thinking rollup, agents overlay (incl. compare view); keep token counts
- Desktop Command Center: drop cost stat, per-model cost, actual-cost hint

Underlying estimate_usage_cost / format_cost / insights cost columns are
left intact but no longer surfaced (display-only change, reversible).

* test: update TUI + gateway + CLI tests for removed cost/cache-hit reporting

- CLI /usage test asserts cost/cache lines are absent, tokens present
- gateway /usage test drops cost + cache asserts; removes cost-included test
- TUI subagentTree summary expectation drops the cost segment
- useConfigSync + appChrome status-rule tests drop showCost prop/state

Subject: [PATCH 237/244] fix(cron): add default retention to per-run job
 output (#52383) (#52646)

* fix(cron): add default retention to per-run job output to bound disk usage (#52383)

Per-run cron output (cron/output/<job>/<timestamp>.md) is written once
per execution and was never pruned, so a frequently-scheduled job on
a long-running deploy accumulates one file per run indefinitely and
can fill the volume ('no space left on device').

save_job_output() now keeps the most recent N output files per job and
removes older ones. N defaults to 50 and is configurable via
cron.output_retention; a non-positive value disables pruning for
operators who manage cleanup externally.

Salvaged from #52402 by @0xDevNinja.

Closes #52383

* fix(config): add cron.output_retention to DEFAULT_CONFIG

Follow-up to #52383: the retention config key was functional via
get()-with-default but missing from DEFAULT_CONFIG, so the deep-merge
wouldn't auto-populate it for new installs. Add it explicitly.

Subject: [PATCH 238/244] fix(update): default pre-update backup to off
 (#52729)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The pre-update HERMES_HOME zip shipped on by default (DEFAULT_CONFIG +
runtime fallback both True), so every `hermes update` zipped the entire
~/.hermes — sessions DB, caches, skills — adding minutes to each update.
The shipped cli-config.yaml.example, the --backup help, and the example
config all already said "off by default," so the live default
contradicted its own documentation.

Flip the default to off everywhere: DEFAULT_CONFIG, the runtime
`.get(..., False)` fallback in _run_pre_update_backup, and the stale
--backup help string. Users who want the #48200 safety net opt in via
updates.pre_update_backup: true or --backup for a single run.

Updated test_default_enabled_creates_backup -> test_default_disabled_is_silent
to assert the new default (silent no-op, no zip).

Subject: [PATCH 239/244] fix(state): resolve compression chain tip in
 resolve_resume_session_id

After context compression, the parent session holds pre-compression messages
and a child (or deeper descendant) holds the continuation.
resolve_resume_session_id() short-circuited when the input session already
had messages (row is not None -> return session_id), causing REST API
endpoints, gateway resume, and CLI resume to serve stale parent messages.

Remove the early-return. Walk the full descendant chain, record the
deepest node that has messages (best), and return best if not None
else the original session_id (preserving the empty-chain fallback).

Callers (api_server.py, web_server.py, cli_agent_setup_mixin.py,
cli_commands_mixin.py) all use the resolved != input -> redirect pattern
and are transparent to this change.

Subject: [PATCH 242/244] fix(state): exclude delegate/branch/tool children
 from resume walk + reconcile salvaged fixes

Follow-up to the salvage of #45035 + #48682. The two PRs touched different
functions (resolve_resume_session_id vs get_compression_tip) but #45035's
descendant walk followed ANY parent_session_id child, so a delegate/subagent
child could hijack the resume target. Apply the same _branched_from /
_delegate_from / source!='tool' exclusion the rest of hermes_state.py uses,
so the resume walk only follows genuine compression continuations.

Also updates the unrealistic delegation test fixture to carry the real
_delegate_from marker, and updates 3 list_sessions_rich test mocks for the
order_by_last_active kwarg #48682 added.

AUTHOR_MAP: map PINKIIILQWQ + ailang323 salvage authors.

Subject: [PATCH 244/244] fix(approval): fold Windows absolute home paths in
 dangerous-command detection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The detector folds absolute home / Hermes-home prefixes into their canonical
~/ and ~/.hermes/ forms so static patterns catch /home/alice/.bashrc the same
way they catch ~/.bashrc (abd69b81). On native Windows this fold never fired,
so terminal commands writing to shell startup files, ~/.ssh/authorized_keys,
or ~/.hermes/config.yaml / .env returned "safe" and skipped the approval
prompt — and config.yaml carries the approval policy itself.

Two compounding causes:

1. The fold ran after the backslash-escape strip (r\m -> rm), which dissolves
   the backslash separators in a Windows path (C:\Users\alice\.bashrc ->
   C:Usersalice...) before the fold could match. It now runs before the strip.
2. The fold only recognized POSIX absolute paths and only the home prefix,
   leaving multi-segment backslash suffixes (\.ssh\authorized_keys) to be
   mangled by the strip.

Consolidated into _home_prefix_fold_regex / _fold_home_prefixes: match a home
prefix with either separator, capture the rest of the path token, and
normalize its separators to / so multi-segment patterns match. The
degenerate-path guard generalizes count("/") >= 2 to "at least two components
below the root" (also rejecting a bare drive root C:\). HOME is consulted
directly because Windows' expanduser ignores it; the more specific Hermes home
is folded first, longest candidate first, so neither fold clobbers the other.

POSIX behavior unchanged; the r\m -> rm anti-obfuscation strip still runs.
Adds TestWindowsAbsolutePathFolding, which monkeypatches a Windows-style
HOME/HERMES_HOME so the behavior is also exercised on the CI runner.
