00c46b8ff9 test(tui): cover heapdump opt-in gate + retention; add AUTHOR_MAP
On-disk vitest coverage for the auto-heapdump disk-safety guard: opt-in
gating (suppressed diagnostics-only path), truthy-spelling acceptance,
manual-trigger passthrough, and the retention prune. Test approach
adapted from #21780 (briandevans) and #21822 (LeonSGP43), reconciled to
the merged gate semantics. Maps alarcritty into AUTHOR_MAP for CI.

8ae0d054f4 fix(tui): guard automatic heap dumps against disk fill
Automatic heap dumps from the TUI memory monitor could write multi-GiB
  .heapsnapshot files on every threshold cross, growing ~/.hermes/heapdumps
  to tens of GiB. Add four layered safeguards:

  - Gate auto-high/auto-critical snapshots behind HERMES_AUTO_HEAPDUMP=1;
    manual dumps remain unchanged.
  - Always write the lightweight diagnostics JSON sidecar so users still
    get an actionable artifact when the snapshot is suppressed.
  - Cap total bytes in the dump dir (HERMES_HEAPDUMP_MAX_BYTES, default
    2 GiB), evicting oldest first, retaining the newest.
  - Add a cooldown between auto dumps (HERMES_AUTO_HEAPDUMP_COOLDOWN_MS,
    default 10 min) so an oscillating heap can't re-trigger.

  Closes #21767

825629424d fix(tui): persist timed-out/cancelled clarify prompts in transcript
When a clarify prompt times out (backend _block returns an empty answer
after the configured timeout) or is dismissed with Esc/Ctrl+C, the live
ClarifyPrompt overlay was torn down by turnController.idle() ->
resetFlowOverlays() with no persistent transcript record. The question and
options vanished from the screen while the agent's follow-up still referred
to "the options above".

The answered path already persists the question + answer; only the
unanswered exits left no trace. This asymmetry is the bug.

Fix (TUI layer only, no Python/protocol change):
- formatAbandonedClarify() in lib/text.ts renders the question + the same
  1-based numbered option list shown by ClarifyPrompt, plus a reason
  ('timed out' / 'cancelled').
- Timeout: createGatewayEventHandler flushes a still-live clarify into the
  transcript as a plain system line when the clarify tool's own tool.complete
  fires. A live capture of the event stream confirmed this is the only point
  where the overlay is still set after a timeout: the sequence is
  clarify.request -> (timeout) -> tool.complete -> message.complete, with NO
  intervening message.start/tool.start. On a real answer, answerClarify()
  clears the overlay before tool.complete arrives, so the hook no-ops there
  (no double-write); a per-requestId guard set is belt-and-braces.
- Explicit cancel: answerClarify('') persists the prompt as a system line
  instead of a transient 'prompt cancelled' flash.

System lines always render (unlike trail lines, which /details can hide),
so the record reliably survives on screen as standard output.

Verified live in the TUI: an Esc-cancelled clarify now leaves the question +
options + '(cancelled - no selection)' in the transcript after the turn ends.

Tests: formatAbandonedClarify unit cases + gateway-handler behavioral cases
(persist on clarify tool.complete, no flush on a non-clarify tool.complete,
no double-persist on repeat tool.complete, no-op when the overlay was already
cleared by an answer).

fix(tui): stop persisting full tool output in trail lines (silent OOM death)
A heavy --tui session (browser snapshots, large tool outputs) silently
OOM-killed the Node parent within minutes — closing the gateway child's
stdin, which the user saw only as a bare "gateway exited" / stdin EOF.
CLI was immune. Root cause: each completed tool's verbose trail line
embedded up to 16KB of result_text, persisted in transcript Msg.tools[]
for the whole session and rendered EXPANDED by default, so an Ink
render-node tree was built for every one of up to 800 messages at once.
That tree blew past Node's heap at a few hundred MB — far below the 2.5GB
memory-monitor exit threshold, so the death was never even attributed.

- text.ts: persisted verbose tool-trail blocks now cap to a small preview
  (VERBOSE_TRAIL_MAX_CHARS=800/12 lines), not the 16KB live-render budget.
  Retained trail strings drop ~17x (12.2MB -> 0.7MB at 800 msgs); the live
  streaming tail still uses the larger LIVE_RENDER budget.
- tui_gateway/server.py: lower the gateway-side verbose text cap to match
  (1KB/16 lines) so we stop shipping output the TUI no longer renders.
- memoryMonitor.ts: derive critical/high thresholds from the real V8 heap
  ceiling (~88%/70%) instead of the hardcoded 2.5GB that killed the process
  at 31% of an 8GB ceiling; add a one-shot onWarn early-warning on fast
  sub-threshold heap growth so the next such death is diagnosable, not silent.
- entry.tsx: wire onWarn to a crash-log breadcrumb + stderr line.

Full tool output is unchanged in the agent context and SQLite session — this
is display/transport only, no behavior or context change.

Fixes #34095. Related #27282.

Tests: ui-tui text + new memoryMonitor suites (33 pass), python verbose-cap
guard (5 pass); full ui-tui suite shows no new failures vs pristine main.
E2E repro confirms the retention drop.

dfba3f3e51 fix(tui): clear selection on right-click copy + group transcript blocks
Two TUI polish fixes.

(1) Right-click copy now clears the highlight.
The right-click handler copied an active selection via onCopySelectionNoClear
(the copy-on-select variant that keeps the highlight during a drag) and never
cleared it, so after right-click-to-copy the selection stayed lit with no
confirmation and a follow-up right-click re-copied the stale range instead of
pasting. A successful right-click copy now clears the selection and notifies;
if the copy fails (no clipboard path) the highlight survives and we fall back
to the right-click paste handler, exactly as before.

(2) Group transcript blocks so boundaries read clearly.
Model replies, reasoning/tool trails, and system/error notes rendered with no
vertical separation, so distinct block types butted together and were hard to
scan. Group adjacent blocks by kind: one blank line opens only where the visual
group changes (model prose <-> reasoning/tool trails <-> notes), while a run of
same-kind blocks renders flush. The rule lives in domain/blockLayout.ts
(messageGroup + hasLeadGap) and is applied intrinsically in MessageLine via a
`prev` prop, which fixes the things ad-hoc per-block margins kept breaking:

  - Streaming stability: the gap is derived from the stable predecessor, never
    the live block's own changing text, so the actively-streaming reply computes
    the same gap while it streams as the settled segment does once it flushes.
    No reflow/jump.
  - Transparent empty trails: a trail hidden by /details, or one carrying only a
    token tally (the finalDetails segment message.complete appends), renders
    nothing and is transparent to grouping (prevRenderedMsg skips it), so there
    are no floating gaps, no doubled gap after a prompt, and no padded space
    above the final reply. In the default/collapsed modes content-bearing trails
    always render, so the grouping is a no-op there.

The virtual-height estimator counts the group-boundary line so scroll math
stays accurate before Yoga remeasures.

ui-tui/src/domain/blockLayout.ts (new), components/messageLine.tsx,
components/streamingAssistant.tsx, components/appLayout.tsx,
lib/virtualHeights.ts, app/useMainApp.ts.

Tests: blockLayout.test.ts (grouping + hidden/empty-trail visibility),
virtualHeights leadGap, app-mouse.test.ts copy behavior. Full ui-tui suite
green apart from 3 pre-existing local/env failures (cursorDrift, ink-resize,
virtualHeights user-prompt-width) unchanged from main.

7527e7aeac feat: fuzzy search for the model picker (WebUI + TUI)
Adds fuzzy subsequence matching with quality ranking to the model
pickers, replacing the WebUI's exact-substring filter and giving the
TUI a search where it previously had none.

- New fuzzy scorer (ui-tui/src/lib/fuzzy.ts + an identical copy at
  web/src/lib/fuzzy.ts, since the two are separate TS packages with no
  shared module). Matches a query as an ordered subsequence (so `g4o`
  matches `gpt-4o`), scores by quality (exact > prefix > word-boundary >
  contiguous > scattered) and returns matched character positions for
  highlighting. Multi-token AND semantics (`clad snnt` -> claude-sonnet).
  15 vitest tests cover the algorithm.

- WebUI ModelPickerDialog: ranked fuzzy filter on providers + models;
  matched characters in model rows are highlighted via <mark>.

- TUI modelPicker: type-to-filter on the provider and model stages with
  live ranking. Backspace edits the filter, Ctrl+U clears it, Esc clears
  a non-empty filter before navigating back. Persist-global / disconnect
  shortcuts moved from g/d to Ctrl+G / Ctrl+D so letters feed the filter.

243e836dce feat(tui): wire /rewind through command.dispatch + prefill payload (#21910)
Adds the TUI half of the /rewind feature so the Ink terminal UI gets
the same affordance as the prompt_toolkit CLI.

Python side (tui_gateway/server.py):
- /rewind added to _PENDING_INPUT_COMMANDS so slash.exec rejects it
  and the TUI falls through to command.dispatch (the only path with
  access to live session state + memory hooks).
- New command.dispatch branch for name == "rewind":
  v1 auto-picks the most recent user turn (Claude-Code-style single-
  step undo), calls SessionDB.rewind_to_message, refreshes the
  in-memory history, fires _memory_manager.on_session_switch with
  rewound=True, and returns the new "prefill" payload.
- A dedicated picker overlay (multi-step rewind) is tracked as a
  follow-up to #21910.

TS side (ui-tui/src/):
- New "prefill" variant on CommandDispatchResponse + asCommandDispatch
  validator. Mirrors "send" but does NOT auto-submit; the client drops
  the message into the composer for editing.
- createSlashHandler renders the optional notice via sys() and calls
  ctx.composer.setInput(d.message), letting the user edit-and-resubmit
  the rewound turn — the core UX promised by the issue.

Tests:
- 7 new tui_gateway tests covering prefill payload shape, in-memory
  history truncation, DB soft-delete, memory-provider notification
  (rewound=True), busy-session refusal, missing-session error, and
  registry placement in _PENDING_INPUT_COMMANDS.
- Extended asCommandDispatch vitest covering the new prefill variant
  (with + without notice, and rejection of malformed payloads).

Out of scope for v1 (tracked as #21910 follow-up):
- Dedicated picker overlay in Ink (the multi-step rewind UI). v1 auto-
  picks the most recent user turn, matching the most common case.
- Gateway platforms (Telegram, Discord, etc.) — issue scopes v1 to
  CLI + TUI only.

Add Hermes desktop app (#20059)
* feat: better composer etc

* docs: add desktop and dashboard run instructions

* fix(desktop): address security scan findings

* fix(dashboard): resolve @nous-research/ui path under npm workspaces

The sync-assets prebuild step shelled out to 'cp -r
node_modules/@nous-research/ui/dist/fonts ...' with a path relative
to apps/dashboard/. That works only when the dep is installed
locally in the dashboard workspace, but 'npm install' at the repo
root (the documented setup — see apps/desktop/README.md) hoists
shared deps to the root node_modules under npm workspaces. The
relative cp then fails with 'No such file or directory', sync-assets
exits 1, the Vite build aborts, and 'hermes dashboard' surfaces a
generic 'Web UI build failed' message.

Replace the shell one-liner with scripts/sync-assets.cjs, which
walks up from the dashboard directory looking for node_modules/
@nous-research/ui — working in both the hoisted (workspaces) and
co-located (standalone) layouts. Also guards against a missing
dist/fonts or dist/assets with a clearer error pointing at a
rebuild of the UI package rather than silently copying nothing.

* feat(desktop): support connecting to a remote Hermes backend

Add HERMES_DESKTOP_REMOTE_URL and HERMES_DESKTOP_REMOTE_TOKEN env
vars that, when set, short-circuit the local-child spawn in
startHermes() and connect the Electron renderer to an already-
running 'hermes dashboard' server reachable over the network.

Motivating use case: WSL2 users who want to run the Hermes core
(agent loop, tools, filesystem access) inside their WSL
distribution while rendering the Electron GUI on native Windows.
Before this change, the desktop app always spawned a local Python
child on the same host as the renderer, which doesn't cross the
WSL/Windows boundary.

The remote path reuses waitForHermes() as a liveness probe
(/api/status is in the backend's public endpoint allowlist), so
the connection is only returned once the backend is actually
ready. WebSocket URL derivation picks ws:// or wss:// based on
the input scheme. URL validation rejects non-http(s) schemes and
requires both env vars together to avoid a half-configured
connection that would silently fall through to the spawn path.

No behaviour change when the env vars are unset — the default
local-spawn flow is untouched.

Typical usage:

  # in WSL2
  hermes dashboard --tui --no-open --host 0.0.0.0 --port 9119 --insecure

  # on Windows
  set HERMES_DESKTOP_REMOTE_URL=http://localhost:9119
  set HERMES_DESKTOP_REMOTE_TOKEN=<session token>
  set HERMES_DESKTOP_IGNORE_EXISTING=1
  (launch Hermes desktop)

* ci(desktop): automate desktop releases

Add GitHub Actions release channels for signed desktop installers and document the stable/nightly download paths.

* feat: file tabs

* refactor(desktop): tighten right-rail tab close API

Promote closeRightRailTab/closeActiveRightRailTab as the single
public entry point. Drops the activeTabRef + handleCloseDocument
indirection in ChatPreviewRail, the unused $rightRailHasContent
atom, and the legacy dismissFilePreviewTarget alias. -70 LOC.

* feat(desktop): polish composer pill toward reference look

Solid foreground-on-background send/voice-conversation circle (black-on-white
in light, white-on-black in dark) anchors the right edge as the primary CTA
instead of the orange theme primary. Bumps the primary control to 2.125rem so
it visually outranks the ghost mic/plus controls. Opens up the surface padding
(0.625rem x / 0.5rem y) so the input row breathes around its controls, and
nudges the corner radius from 20 to 24px for a slightly pill-ier silhouette.
LiquidGlass distortion is preserved.

* feat(desktop): add startup and onboarding flow

Add phase-based desktop boot progress, fresh-install sandbox testing, and first-run provider credential onboarding so packaged installs can start cleanly without manual settings detours.

* fix(desktop): gate prompts on provider setup

Show the desktop provider onboarding flow before prompt submission when no inference provider is configured, preventing fresh installs from falling through to backend credential errors.

* fix(desktop): surface provider onboarding from session warnings

Propagate credential warnings through session runtime info and open desktop onboarding whenever a session reports no usable provider, so unconfigured installs cannot fall through to prompt errors.

* fix(desktop): route gateway provider errors to onboarding

The "No inference provider configured" auth error reaches the renderer through gateway error events, not the prompt.submit promise; the previous patch only caught the latter, so the error toast still surfaced and onboarding never opened.

Also strip credential-shaped env vars from the test:desktop:fresh sandbox so the packaged backend can't see provider keys leaking from the launching shell.

* fix(desktop): use strict runtime check to drive onboarding

setup.status returned True whenever any provider auth state was discoverable, including indirect fallbacks like a gh-CLI Copilot token. That made desktop think the user was set up while the agent's actual resolve_runtime_provider call still raised AuthError, leaving the user with a useless toast and no onboarding.

Add a setup.runtime_check gateway method that runs the same resolver the agent uses on session creation, and switch the desktop onboarding overlay and prompt precheck to use it.

* feat(desktop): OAuth-first onboarding using existing dashboard provider API

Replace the engineer-flavored API key form with a Sign-in-first onboarding overlay that uses the dashboard's existing /api/providers/oauth catalog and PKCE/device-code endpoints (Anthropic, Nous, OpenAI Codex, etc.). API key entry is now a fallback tab with friendly provider names instead of env var prefixes, and the loud raw resolver error is gone in favor of a one-line welcome message.

* fix(desktop): polish onboarding provider list

Reorder OAuth providers so Nous Portal is first, give the segmented Sign in / API key control equal column widths, and replace the engineer-flavored backend names like "Anthropic (Claude API)" / "MiniMax (OAuth)" with friendlier in-app titles. External-CLI providers now show a softer subtitle and an external-link icon instead of a chevron.

* refactor(desktop): split onboarding overlay into store + view

Move the OAuth state machine, runtime check, copy-to-clipboard, and api-key save into store/onboarding.ts (matching the boot.ts pattern), leaving the overlay as a presentation layer that subscribes via useStore. Tabs are now table-driven, child panels read flow from the store instead of prop-drilling, and the polling/PKCE/error/success branches share a small Status atom.

* fix(desktop): external CLI providers + center mode tabs

External-CLI providers (Claude Code, Qwen Code) now open an in-overlay panel with the CLI command, copy button, and an "I've signed in" recheck instead of firing an invisible toast. Center the Sign in / API key tab control so it sits under the heading instead of hugging the left edge.

* fix(desktop): drop onboarding tabs for an inline link, group device-code waiting state

Replace the Sign in / API key tab pair with an "I have an API key" footer link under the OAuth provider list, with a "Back to sign in" affordance inside the API key form. Group the device-code "Waiting for you to authorize..." status next to the Cancel button so the alignment matches the action.

* refactor(desktop): tighten onboarding store + overlay

Drop the dead isOnboardingBusy/BUSY set, factor the catch-fallback dance into safeReq, and share a single reloadAndConnect helper between PKCE submit, device-code success, external recheck, and api-key save.

In the overlay, extract Step / CodeBlock / FlowFooter / CancelBtn / DocsLink atoms so the four sign-in panels share the same chrome instead of repeating it inline. Net effect: fewer literal divs, one place to touch the spacing, and the code-block + footer rows are reusable across future flows.

* fix(desktop): mount onboarding from frame 1 to kill the FOUT

Default onboarding.configured to null (unknown until the runtime check resolves) and have the onboarding overlay render whenever it's not yet confirmed true. The boot overlay now yields to it, so the very first paint is the Welcome card with a "While we get you set up..." progress strip instead of a flash of the chat shell between boot dismiss and onboarding mount.

The picker swaps in cleanly once the gateway opens and the runtime check confirms the user is not configured. Already-configured users see the same prep card briefly while their existing runtime warms up, then the overlay dismisses without touching the chat shell.

* fix(desktop): top-align empty sessions placeholder

The "Start a chat to build your history." empty state used a min-h-35 grid place-items-center container, which floated the text in a tall dead zone. Render it as a flat paragraph that sits right under the section header like the empty pinned state does.

* refactor(desktop): drop dead boot overlay

Onboarding overlay subsumes the boot card now that it mounts from frame 1 and renders boot progress inline. The standalone DesktopBootOverlay is unreachable in every flow (yields whenever onboarding has not confirmed configured, dismisses once it has).

* fix(desktop): hide pinned/recents sections until first session

A fresh sidebar showed the Pinned and Recent chats headers with floating empty-state copy underneath. Drop both sections (and the now-orphan SidebarEmptySessionState) when there are no sessions yet — they reappear after the first chat. Skeletons during initial load are unchanged.

* feat(gui): route embedded TUI through dashboard gateway (#21979)

Inject HERMES_TUI_GATEWAY_URL into dashboard PTY sessions so embedded ui-tui instances attach to the in-process websocket gateway, with coverage for the new env wiring.

* Add desktop remote gateway settings

Make the desktop gateway connection configurable from settings so local remains the default while remote backends can be saved, tested, and applied without environment variables.

* feat(gui): first-class Messaging page + gateway menu redesign

- Add Messaging page to the desktop app with per-platform setup,
  status, and inline guidance. Catalog derives from gateway.config
  Platform enum + plugin registry, so every messaging adapter the CLI
  supports (Telegram, Discord, Slack, Mattermost, Matrix, WhatsApp,
  Signal, BlueBubbles, Home Assistant, Email, SMS, DingTalk, Feishu,
  WeCom, Weixin, QQ, Yuanbao, API server, Webhooks, plugins) shows up
  without per-platform code.
- New REST endpoints: GET /api/messaging/platforms, PUT and POST
  /test on the same path. Secrets go through the existing .env
  pipeline; enable/disable writes config.yaml.
- Replace gateway statusbar dropdown with a richer panel: status row,
  icon-only restart + system-panel actions, recent activity (with
  timestamps trimmed in display, full text on hover), platform list.
- Auto-poll the messaging page every 6s (paused when hidden) so
  status updates without a manual check.
- Drop Settings / Command Center from the sidebar nav (still
  reachable via shortcuts and the titlebar cog).
- Flatten top corners on Messaging/Skills/Artifacts/Chat panes.
- Share new StatusDot component across messaging + gateway menu.
- Fix gateway/config.py so an explicit platforms.<name>.enabled=false
  in config.yaml is honored when env tokens are present.
- pb-9 on the chat content area for breathing room above the composer.

* Potential fix for pull request finding 'CodeQL / Clear-text logging of sensitive information'

Co-authored-by: Copilot Autofix powered by AI <62310815+github-advanced-security[bot]@users.noreply.github.com>

* pin electron version

* hide application menu on non-mac systems

* interpret compactPreview for non-string vlaues as JSON or an empty string

* fix(desktop): keep composer contenteditable mounted across stacked toggle

The composer rendered {input} inside two different parent fragments
depending on `stacked`. When auto-expand flipped `stacked` (e.g. the
moment typed text wrapped past two lines), React reconciled the two
branches as different positions and unmounted/remounted the
contenteditable. The fresh mount started empty, so any in-flight
characters — most reliably reproduced by holding a key — were lost.

Replace the conditional with a single CSS Grid whose template-areas
swap on `stacked`. The three children (menu, input, controls) keep
stable identities across the toggle; only their grid placement
changes, which the browser handles without React tearing down the
editor.

* refactor(desktop): align install layout with install.ps1 / install.sh

Make the desktop app's runtime layout match what scripts/install.ps1 and
scripts/install.sh produce, so a desktop-only user and a CLI-only user end
up with the same files in the same places and can share one install.

Layout
- ACTIVE_HERMES_ROOT = HERMES_HOME/hermes-agent  (was: process.resourcesPath/hermes-agent, read-only)
- VENV_ROOT          = HERMES_HOME/hermes-agent/venv  (was: userData/hermes-runtime)
- desktop.log        = HERMES_HOME/logs/desktop.log  (was: userData/desktop.log)
- HERMES_HOME default: %LOCALAPPDATA%\hermes on Windows, ~/.hermes elsewhere

The packaged .app/.exe still ships a read-only payload at
process.resourcesPath/hermes-agent (FACTORY_HERMES_ROOT). On first launch
or after an installer-driven upgrade we sync factory -> active, then
provision the venv and run pip install -e . against the active root.

Key behaviors
- Pin HERMES_HOME in the spawned Python's env so get_hermes_home() resolves
  to the same path resolveHermesHome() picked. Without this, Python falls
  back to ~/.hermes on every platform - fine on mac/linux, a split-state
  bug on Windows where our default is %LOCALAPPDATA%\hermes.
- Detect developer installs by .git presence at ACTIVE; never overwrite
  a user's checkout via factory sync.
- Marker at ACTIVE/.hermes-desktop-runtime.json (schema v4) tracks
  pyproject hash + factory version + runtime schema version. depsFresh
  fast-paths when nothing changed.
- Dev (npm run dev) prefers SOURCE_REPO_ROOT over ACTIVE so devs run
  their local edits, not whatever's under HERMES_HOME.
- Better error messages distinguish "no payload" from "no Python".
- Preserve a legacy ~/.hermes on Windows when no %LOCALAPPDATA%\hermes
  exists, so users with prior pip/manual installs aren't orphaned.

pyproject.toml
- Promote fastapi, uvicorn[standard], ptyprocess (non-Windows), and
  pywinpty (Windows) to main dependencies. The dashboard backend
  (hermes dashboard) needs them at runtime; the previous lazy-import
  fallback was a footgun for fresh installs.
- Empty the [pty] optional-extra; kept as a no-op back-compat alias for
  any existing pip install hermes-agent[pty] invocations.

Drops the hardcoded BUNDLED_RUNTIME_REQUIREMENTS list in main.cjs - the
desktop now installs whatever pyproject.toml says, single source of truth.

Files
- apps/desktop/electron/main.cjs:    runtime layout, HERMES_HOME pin,
                                      factory->active sync, marker v4
- apps/desktop/scripts/test-desktop.mjs:  track new venv location
- apps/desktop/README.md:            new Setup, Runtime Bootstrap, and
                                      Debugging sections
- pyproject.toml:                    fastapi/uvicorn/pty backends in main
                                      dependencies; [pty] extra emptied

Tested locally on Windows: npm run dev boots cleanly, sessions land at
the new location, type-check + lint + test:desktop:platforms all pass.
Verified end-to-end on a fresh Win11 VM via dist:win installer.

Known gaps (filed as follow-ups, not in this PR):
- Skills not seeded on packaged installs (sync_skills only runs in
  cmd_chat, not cmd_dashboard). Need to move to shared pre-dispatch.
- Git Bash not bundled or detected; agent's terminal tool errors out
  with a useful message but desktop bootstrapper should pre-flight it.
- install.ps1 / install.sh should be decomposed into composable phase
  libraries so the desktop bootstrapper can reuse them as a single
  source of truth across all install surfaces.

* feat(desktop): theme polish, prose chat typography, composer chrome

- DS tokens/midground, Backdrop, scoped scrollbars, typography plugin + prose
- Composer liquid/radius utilities, thread font parity, tool/thinking cues
- File tree label scale, preview flex, thread retry loading + streaming tests

* feat(desktop): NSIS prereq detection page + auto-install via winget

The packaged Windows installer now detects Python 3.11+ and Git for Windows
at install time and offers to install missing prereqs via winget. Mirrors
the prereq logic scripts/install.ps1 already runs for CLI installs, so
desktop installer users get the same out-of-the-box experience as
install.ps1 users.

Why
- Hermes' terminal tool calls bash.exe directly (tools/environments/
  local.py); on Windows that's Git Bash from Git for Windows. Without it,
  the agent fails on the first terminal() call.
- Hermes' Python runtime needs 3.11+. Without it, the desktop bootstrapper
  errors out at venv creation.
- Both gaps surfaced on a fresh Windows 11 VM smoke test: VM had Python
  pre-installed but no Git, so the agent's first terminal call failed
  with "Git Bash isn't installed."
- install.ps1 has had Install-Git + Install-Uv functions for ages. The
  desktop installer was the asymmetric outlier.

How — NSIS prereq page
- New file: apps/desktop/installer/prereq-check.nsh (plugged into
  electron-builder via build.nsis.include)
- Real Wizard page using nsDialogs, inserted via customPageAfterChangeDir
  hook (between the Directory page and InstFiles).
  - Group boxes for Python and Git, each showing detection status.
  - Pre-checked install checkboxes when winget is available.
  - Auto-skips silently if both prereqs are already installed.
  - Falls back to manual download URLs when winget itself is missing.
- Detection:
  - Python: probes `py -3.11`/`-3.12`/`-3.13`/`-3.14` via the Python
    launcher. Microsoft Store "Python stub" (no py.exe) is correctly
    classified as not-installed.
  - Git: `where git`.
  - winget: `where winget` (Win10 1809+ / Win11 with App Installer).
- Install execution (in customInstall macro):
  - Python: nsExec::ExecToLog with `--scope user --silent`. Per-user
    install, no UAC prompt, output streams to install log.
  - Git: ExecShellWait via Windows ShellExecute. Critical because Git
    always installs per-machine and triggers UAC; ShellExecute preserves
    the foreground focus chain across non-elevated → elevated process
    spawns, so UAC actually comes to the foreground. nsExec::ExecToLog
    breaks the chain because winget runs hidden.
  - Both pass `--disable-interactivity --accept-package-agreements
    --accept-source-agreements` to suppress winget's own dialogs.
- Verification: probes Git's standard install locations via FileExists
  rather than `where git`. NSIS's process inherits PATH at startup, so
  a freshly-installed Git won't be visible to `where` until restart.
- Silent installs (/S) skip the prompts; managed deploys handle prereqs
  out-of-band via Group Policy / Intune.

How — Electron-side safety net
- New findGitBash() in main.cjs, parallel to findSystemPython(). Probes
  the same locations as tools/environments/local.py:_find_bash() so a
  positive result here means the agent's terminal tool will work.
- ensureRuntime now throws a clear, actionable error on Windows when Git
  Bash isn't found, matching the existing "Python 3.11+ is required"
  error path.
- Catches users the NSIS page doesn't: .msi installer users (NSIS prereq
  page doesn't run for MSI), `npm run dev` users, manual installers,
  anyone who unchecked the install boxes on the NSIS prereq page.
- All gated on `IS_WINDOWS`; macOS / Linux unaffected.

NSIS build issue (resolved)
- electron-builder defaults to `-WX` (warnings as errors). NSIS optimizer
  emits "warning 6010: function not referenced" for our page functions
  because Page custom directives don't count as references in its
  static-analysis pass. The functions ARE called at runtime when NSIS
  invokes the page; the optimizer just can't see it statically.
- Set `build.nsis.warningsAsErrors=false` in package.json so this
  spurious warning doesn't fail the build. (Documented option from
  electron-builder's nsisOptions.)

Out of scope (filed for future work)
- MSI prereq detection: Windows Installer custom actions are a different
  mechanism. Enterprise deploys typically handle prereqs via GP/Intune.
- Bundle PortableGit + python-build-standalone in extraResources for
  zero-network installs. ~80MB increase.
- Mac / Linux GUI prereq flows (different installer formats; Xcode CLT
  covers most macOS prereqs already; Linux is per-distro hard).

Files
- apps/desktop/installer/prereq-check.nsh   (new, ~290 lines NSIS)
- apps/desktop/package.json                 (build.nsis.include +
                                              warningsAsErrors)
- apps/desktop/electron/main.cjs            (findGitBash + preflight)
- apps/desktop/README.md                    (Runtime prerequisites
                                              section)

Cross-platform impact
- macOS / Linux builds (dist:mac, dist:mac:dmg, dist:mac:zip): nsis
  config is ignored entirely; .nsh is dormant.
- npm run dev: .nsh dormant; main.cjs preflight gated on IS_WINDOWS.
- scripts/install.ps1, scripts/install.sh: no reference to any new
  files; CLI install paths untouched.
- Hermes CLI / dashboard / gateway: no reference; runtime untouched.
- All checks: node --check on main.cjs and test-desktop.mjs pass;
  npm run test:desktop:platforms 4/4 passing; node --test green.

Tested
- npm run dist:win produces signed .exe and .msi without errors.
- Fresh Win11 VM (Python pre-installed, no Git): prereq page renders,
  Python check shows detected, Git checkbox pre-checked. Click Next →
  Git installs via winget with UAC prompt in foreground.
- After install completes, Hermes launches and the agent's terminal
  tool can run bash commands. Verified Git Bash is detected at
  `C:\Program Files\Git\bin\bash.exe` by ensureRuntime's preflight.

* feat: theme changes, composer tweaks, in app update ux, finesse

* fix(cli): seed bundled skills on dashboard + gateway entrypoints

`sync_skills(quiet=True)` was only being called from inside `cmd_chat`,
which meant `hermes dashboard` (the desktop GUI's backend) and `hermes
gateway` (Telegram/Discord/Slack/etc daemons) never seeded the bundled
skill library into ~/.hermes/skills/.

This surfaced as "No skills found" in the desktop GUI's skills panel on
fresh installs, despite the agent having access to the full bundled
library when invoked via `hermes chat`. scripts/install.ps1 worked
around it by running skills_sync.py as part of Copy-ConfigTemplates,
but that's not part of the desktop installer's bootstrap chain.

Fix
- Extract the skills-sync block from cmd_chat into a module-level
  `_sync_bundled_skills_quietly()` helper.
- Call the helper from cmd_chat (preserving existing behavior),
  cmd_dashboard (after the --status/--stop early-return paths and
  fastapi import check, so we don't run skills_sync on management
  commands or when deps aren't installed), and cmd_gateway.

Why these three entrypoints
- cmd_chat: the user's primary CLI entrypoint
- cmd_dashboard: the desktop GUI's backend; this is what `hermes
  dashboard --tui` invokes when the desktop bootstrapper spawns Hermes
- cmd_gateway: long-running daemons where the user expects the agent
  to have full skill access

Other entrypoints (cmd_config, cmd_doctor, cmd_login, cmd_status,
etc.) are management commands that don't need skill discovery and were
never running skills_sync in the first place — leaving them alone.

Idempotence
- tools/skills_sync.py is manifest-based: skipped skills cost
  milliseconds. Calling it from multiple entrypoints adds no real
  cost, and users running `hermes chat` then `hermes dashboard` get
  two fast no-ops on the second call.

Failure handling
- Helper wraps skills_sync in try/except. Skills are an enhancement,
  not a hard dependency — Hermes runs fine with an empty skills/ dir.

Files
- hermes_cli/main.py:
  + new helper `_sync_bundled_skills_quietly()` at module level
  + cmd_chat: replace inline block with helper call
  + cmd_dashboard: add helper call after fastapi import succeeds
  + cmd_gateway: add helper call before delegating to gateway_command

* feat(desktop): hoisted todo widget, JSON tool summaries, history grouping & timer fixes

- Hoist todo to first-class widget (shadcn checkboxes, brand colors, no
  tool-accordion). Header derives label from active task; non-active rows fade.
- Replace raw JSON dumps with structured key/value summaries via
  formatToolResultSummary; nested error extraction for clearer failures.
- Fix loaded-session grouping: stitch interleaved assistant/tool iterations
  into one bubble instead of orphaned synthetic messages.
- Stable tool/thinking timers via keyed registry so unmount/scroll doesn't
  reset elapsed counts; gate "running" on real live thread state.
- Reorganize chat-only assistant-ui components under components/chat/.

* fix(desktop): address CodeQL alerts on PR #20059

- settings/helpers.ts: harden setNested against prototype pollution.
  POLLUTING_PATH_PARTS check is now applied at every assignment site
  (loop + leaf) and uses Object.defineProperty so CodeQL can see the
  guard inline rather than via a helper function call.

- lib/markdown-preprocess.ts: rebuild the dangling-fence close regex
  from a fence-char + length instead of marker.replace(...). The marker
  is captured by `(`{3,}|~{3,})` so it can only be backticks or tildes,
  but CodeQL was tracing tainted input text into the RegExp source and
  flagging hostname dots from input as part of the pattern (false
  positive js/incomplete-hostname-regexp on the test fixture URLs).
  Reconstructing from a literal char breaks the dataflow.

- scripts/notarize-artifact.cjs: drop args from the run() rejection
  message. Args carry --key-id / --issuer / key file path; the existing
  outer catch already squashes errors to a generic line, but CodeQL was
  flagging the args.join(' ') as clear-text logging of APPLE_API_KEY_ID.

Composer DOM-text-as-HTML alerts (composer/index.tsx:379, :547) are
already addressed in 4dd9732a9 — innerHTML assignment was replaced with
renderComposerContents which builds DOM via replaceChildren / append
text nodes (no HTML interpretation).

* fix(desktop): inline prototype-pollution guard so CodeQL sees it

CodeQL's dataflow doesn't follow the helper-function guard inside
`safeSet`, so it kept flagging Object.defineProperty as prototype-
polluting. Inline the literal `__proto__`/`constructor`/`prototype`
check at the assignment site to break the dataflow.

Behavior unchanged — same set of disallowed keys, same throw.

* feat(ui-tui): resolve links to readable page titles

Mirror desktop pretty-link behavior in the TUI by resolving HTTP links to page titles with shared caching and safe fetch filters, plus slug-based fallbacks so chat links stay readable even when title fetch fails.

* fix(desktop): drop RegExp from dangling-fence close detection

Previous attempt tried to break the dataflow by reconstructing the
close-fence regex from a literal char + marker.length, but CodeQL still
traced marker.length back to input and kept flagging the test-fixture
URLs as hostname-regex sources (js/incomplete-hostname-regexp).

Replace `new RegExp(...)` + `closeRe.test(body)` with a string-only
hasCloseFenceLine() helper that splits on '\n' and uses ===. No regex
on this path now, so input data can no longer reach a RegExp source.

Behavior preserved: matches lines that are (whitespace + marker +
whitespace), which is what the original `\n[ \t]*${marker}[ \t]*(?=\n|$)`
matched. All 12 markdown-text tests still pass.

* fix(process-registry): suppress windows-footgun false positive on guarded killpg

Keep the existing POSIX-only process-group teardown path, but make the
signal selection explicit via getattr and add an inline windows-footgun
suppression marker on the guarded os.killpg line so the Windows footgun
check no longer blocks CI on this intentionally platform-gated code.

* feat(desktop): reconcile live tool events, polish thread chrome, harden boot

- chat-messages: match tool rows by overlapping query/context/preview values
  so preview-first `tool.progress` rows reliably adopt later stable-id
  `tool.start` payloads instead of spawning ghost rows or mis-merging
  parallel same-name calls; preserve prior args/result across phases.
- tui_gateway: emit full args + parsed result on `tool.start` / `tool.complete`,
  drop redundant `tool.started` re-emit from `tool.progress`.
- electron/main: prefer SOURCE_REPO_ROOT before PATH `hermes` in dev so
  local backend edits actually run; split hardening helpers into
  `electron/hardening.cjs` with tests.
- thread/tool UI: one-shot enter animation keyed by stable ids, braille
  spinner for running rows, Cursor-like disclosure rows, drill-down +
  duration/count formatting via new tool-fallback-model.
- composer: extract `text-utils`, drop liquid-glass overrides.
- right-rail: split preview-pane into preview-console / preview-file.
- runtime: incremental external-store runtime + runtime-readiness gate;
  onboarding store + tests; route-resume hook test.
- regression tests for live tool reconciliation (parallel tools, id-less
  progress, preview-first rows, structured args/results).

* feat(desktop): add ripgrep to NSIS prereq page + polish layout

Add ripgrep as a third (recommended) prereq alongside Python and Git in
the NSIS prereq detection page, and clean up the page layout based on
on-VM testing.

Why ripgrep
- Hermes' search_files tool calls `rg` directly for content + filename
  search (tools/file_operations.py:1382). Falls back to grep/find from
  Git Bash when missing — works but slower and noisier (no .gitignore
  awareness).
- ~5MB winget install via `BurntSushi.ripgrep.MSVC --scope user` — no
  UAC prompt, parallel to how Python installs.
- scripts/install.ps1 already installs ripgrep as part of
  Install-SystemPackages; this brings the desktop installer to parity.

Why "recommended" not "required"
- Python and Git are hard requirements: without them the agent runtime
  or terminal tool refuses to start. The bootstrapper preflight throws.
- ripgrep is a performance enhancement: missing it just means slower
  searches. Page wording reflects this; failure to install is logged
  but doesn't show a MessageBox or block.

Layout polish (response to on-VM screenshot review)
- Wizard header now correctly reads "System Requirements" instead of
  the leftover "Choose Install Location" from the previous page. Set
  via `GetDlgItem $HWNDPARENT 1037/1038` + WM_SETTEXT — the standard
  NSIS pattern for overriding the page header on a custom Page.
- Removed redundant in-body title + verbose intro paragraph; the
  wizard header IS the title now. Body has one short intro line.
- Group boxes tightened to 26u with content positioned just below the
  groupbox title (not top-anchored status + bottom-anchored checkbox
  with empty space in the middle). All three panels + footer fit
  comfortably in 126u, well under the 140u page limit.
- Checkbox labels simplified: dropped "(per-user, no admin prompt)"
  and "(administrator approval required)" suffixes. The footer note
  still calls out UAC for Git when relevant.
- Footer text trimmed to fit cleanly without clipping.

Install order (in customInstall macro)
- Python → ripgrep → Git
- Python and ripgrep are silent and run first; Git's UAC prompt comes
  last so the user's approval interaction isn't interrupted by silent
  activity afterwards.

Skip behavior unchanged
- All three detected → page auto-skips via Abort
- Silent install (/S) → customInstall winget block skips
- User unchecks all → page advances without running winget

Files
- apps/desktop/installer/prereq-check.nsh: ripgrep detection block,
  ripgrep page panel + checkbox, ripgrep customInstall block,
  GetDlgItem header override, layout reflow
- apps/desktop/README.md: Runtime prerequisites section updated to
  list ripgrep as recommended, with manual winget command

* feat(desktop): add model-confirmation step to onboarding

After OAuth/API-key login completes, onboarding now shows a confirmation
card with the curated default model and a Change button before dropping
the user into chat. Closes the gap where the desktop's `model.default`
was empty after first launch and the agent had to fall back to whatever
heuristic happened to fire — leaving users wondering "why am I getting
sonnet-4 when I logged into Nous Portal?"

Why
- Desktop onboarding only persisted credentials, never `model.default`.
  The CLI's `hermes model` command pairs provider + model selection,
  but the desktop's onboarding skipped the model step entirely.
- Result: users saw whichever model the agent's auto-fallback picked,
  unpredictably and undocumented.
- For the BUILD demo we want users to land on the model they expect
  for their provider, with a clear "this is what you're getting" UI
  and a one-click path to change it before chatting.

How
- New `confirming_model` flow status carries the just-authenticated
  provider slug, current default model, label, and a saving flag.
- `completeWithModelConfirm()` runs after credentials succeed: reloads
  env, verifies runtime, fetches /api/model/options to find the curated
  first-model for the provider, persists it via /api/model/set, then
  transitions into `confirming_model`.
- If anything fails (no providers returned, network error), falls
  through to the previous behaviour — onboarding completes without
  the confirm step. Polish, not a hard requirement.
- All four credential paths (device_code OAuth, PKCE OAuth, external
  CLI flow, API key) now use completeWithModelConfirm instead of
  reloadAndConnect.

UI
- `ConfirmingModelPanel` shows: green "<provider> connected" banner,
  card with "Default model: <name>" + Change button, and a "Start
  chatting" CTA that finalises onboarding.
- Reuses the existing `ModelPickerDialog` (the same picker available
  from the chat shell) for the change-model UX. Search, filtering,
  multi-provider listing — all already built.
- Stacking: ModelPickerDialog defaults to z-130, which renders UNDER
  the onboarding overlay (z-1300) and breaks pointer events. Added
  optional `contentClassName` prop to ModelPickerDialog so callers
  can override; onboarding passes `z-[1310]`.

Provider-slug matching
- For OAuth flows: pass `provider.id` directly as the preferred slug.
- For API-key flows: `OPENROUTER_API_KEY` → "openrouter" via env-key
  prefix strip. Also includes the user-visible label as a fallback
  candidate.
- fetchProviderDefaultModel falls back to the first authenticated
  provider in the response if no preferred slug matches — so even a
  miss still surfaces a reasonable default.

Files
- apps/desktop/src/store/onboarding.ts:
  + new `confirming_model` flow variant
  + fetchProviderDefaultModel + completeWithModelConfirm helpers
  + setOnboardingModel (optimistic update + revert on failure)
  + confirmOnboardingModel (finalises onboarding from the card)
  - reloadAndConnect (replaced; the four call sites now go through
    completeWithModelConfirm)
- apps/desktop/src/components/desktop-onboarding-overlay.tsx:
  + ConfirmingModelPanel component
  + new branch in FlowPanel for status `confirming_model`
  + ModelPickerDialog usage with z-[1310] content class
- apps/desktop/src/components/model-picker.tsx:
  + optional `contentClassName` prop on ModelPickerDialog so the
    dialog can be stacked on top of other fixed overlays

Tested
- `npm run type-check` passes
- `npx eslint` clean on touched files
- Live test in `npm run dev`: cleared onboarding cache, walked
  through Nous device-code flow, saw confirm card with curated
  default, clicked Change → ModelPickerDialog rendered above the
  onboarding overlay with working pointer events, picked a different
  model, "Start chatting" persisted to ~/.hermes/config.yaml.

* fix(desktop): suppress generic provider warning in onboarding

Hide the red setup notice when the message is the generic missing-provider guidance, since onboarding already presents provider auth actions. Centralize provider-setup matching across desktop hooks and add coverage for the matcher.

* fix(desktop): add 2u clearance below prereq checkboxes

Group box bottom border was clipping the checkboxes by 1-2px.
Bumped each box height 26u→30u; checkboxes now sit 2u above the bottom border.

* fix(nix): refresh dashboard lockfile hash

Update the web npm deps hash in nix/web.nix to match the committed apps/dashboard/package-lock.json so bb/gui passes the nix lockfile check.

* fix(desktop): install TUI deps in release workflow

Ensure desktop release builds install the standalone ui-tui package before bundling the TUI payload.

* fix(desktop): run release builder from app package

Invoke the desktop builder through the package script so electron-builder uses apps/desktop/package.json.

* fix(desktop): expand release artifact names safely

Build desktop artifact names from workflow version/channel while preserving electron-builder platform macros.

* fix(desktop): use package artifact naming in release workflow

Let electron-builder's desktop package config provide platform-specific artifact extensions while the workflow injects the release version/channel metadata.

* fix(nix): fetch dashboard npm deps from package root

Point the dashboard npm dependency fetch at apps/dashboard so Nix can find the package lockfile after the dashboard move.

* fix(nix): build dashboard from package directory

Set the web package source root to apps/dashboard so npm patch/build phases run beside the dashboard lockfile while keeping apps/shared available as a sibling.

* feat(desktop): render LaTeX math via KaTeX after streaming completes

Add @streamdown/math plugin to the chat markdown renderer.
Inline ($x^2$) and block ($$...$$) math both supported with
singleDollarTextMath enabled. Plugin is gated to non-streaming state
to match the existing pattern for syntax highlighting — math renders
when the message completes, avoiding KaTeX re-render churn during
streaming. KaTeX CSS is imported in styles.css; ~30KB CSS + ~430KB
JS added to the bundle. Smoothness improvements during streaming
deferred to a follow-up.

* perf(desktop): memoize KaTeX renders so math streams without re-rendering

Wrap rehype-katex with a per-equation LRU cache (keyed by
displayMode + source text) and re-enable math during streaming.

Stock @streamdown/math runs rehype-katex on every markdown commit,
so each new token re-katexes every equation in the message. For
math-heavy responses (an equation derived step-by-step) that's
hundreds of ms of wasted work per token and the streaming UI
chokes. With memoization, each equation pays katex.renderToString
exactly once; subsequent tokens re-walk the tree but hit cache for
unchanged equations.

The wrapper mirrors rehype-katex's semantics exactly: same class
detection (language-math, math-inline, math-display), same
<pre>-walk-up for fenced math blocks, same parent.children.splice
replacement, same SKIP traversal, same strict-then-lenient render
strategy with VFile message reporting.

Cached children are structuredCloned on each splice so downstream
rehype plugins or toJsxRuntime can't mutate the cache.

* fix(desktop): declare katex-memo deps directly + drop per-app lockfile

katex-memo.ts (added in 112cad59b) imports hast-util-from-html-isomorphic,
hast-util-to-text, remark-math, katex, and unist-util-visit-parents but
those were never added to apps/desktop/package.json. They were silently
resolving via @streamdown/math at the workspace root, which broke the
moment `npm i --prefix apps/desktop` ran with the per-workspace lockfile
because that install only consults apps/desktop/package.json. Add them
as direct deps, plus unified/vfile/@types/hast for the type imports.

Also delete apps/desktop/package-lock.json — root package.json declares
workspaces: ["apps/*"], so npm manages all lockfile state at the root.
The stale per-app lockfile is what made `npm i --prefix apps/desktop`
diverge from the workspace install in the first place and left an empty
apps/desktop/node_modules/@assistant-ui/ stub that Vite's dep optimizer
then tried (and failed) to open at @assistant-ui/core/dist/internal.js.

* feat(desktop): disable Backdrop noise overlay by default

The noise overlay defaulted to on, which adds a busy speckle layer over
the whole window for every new user. Flip the Leva default to off; the
toggle stays in Backdrop / Noise for anyone who wants it back.

* fix(desktop): polish LaTeX rendering — currency, code blocks, brackets

Five distinct bugs surfaced from a math-heavy stress test:

1. Adjacent code fences glued together. scrubBacktickNoise's
   second-pass regex /``\s*``/g matched the LAST 2 backticks of
   one fence + whitespace + FIRST 2 backticks of the next, collapsing
   two blocks into one. Fixed with lookbehind/lookahead so we only
   match exactly 2 backticks not part of a longer run.

2. Whitespace eaten between fences and following content.
   stripPreviewTargets internally calls .trim() which strips leading/
   trailing whitespace from each split-segment. For segments between
   two fences this collapsed \n\n to '', gluing fence close to next
   block. Fixed by capturing leading/trailing whitespace at the call
   site and restoring it after the transform.

3. Currency dollar signs eaten as math. With singleDollarTextMath:true
   remark-math greedy-matched any pair of $, so '$5 ... $10' became
   one inline math span. Added escapeCurrencyDollars to escape $<digit>
   patterns to \$<digit> in prose segments (not in code). Trade-off:
   math expressions starting with a digit (rare — '$5x = 10$') get
   escaped too. Mirrors the convention in ChatGPT/Claude's UIs.

4. \(...\) and \[...\] LaTeX brackets unsupported. Models often
   emit these instead of $...$ / $$...$$. Added
   rewriteLatexBracketDelimiters preprocessor pass.

5. ```latex / ```tex blocks were being routed to KaTeX via a
   rewrite to ```math. Aligns with GitHub markdown convention:
   ```math = render as math; ```latex / ```tex = LaTeX/TeX
   source code (syntax highlighted, not rendered). Conflating them
   broke teaching/showing-source use cases. MATH_FENCE_LANGUAGES
   pruned to {'math'} only.

Also flipped parseIncompleteMarkdown to true (was !isStreaming) so
the math parser can't see $ inside streaming-but-not-yet-closed code
fences. Shiki was already deferred via defer={isStreaming} so this
doesn't introduce new tokenization cost.

Test: 18/18 existing tests still pass; one test updated to expect
escaped \$ in currency-prose-with-URL case.

* fix(desktop): detect Python via registry/filesystem; pin to 3.11–3.13

Two related fixes for Python detection on Windows:

1. py.exe (Python launcher) is missing from per-user installs that
   didn't check the launcher option, so 'py -3.X --version' alone
   misses real Python installs. User-reported case: clean Win11 +
   official Python.org 3.14 install -> 'where py' returned nothing,
   our installer offered to install Python again. Both NSIS prereq
   page and main.cjs now probe in this order:
     1. py.exe launcher (when present)
     2. PEP 514 registry: HKLM/HKCU\SOFTWARE\Python\PythonCore\<v>\InstallPath
     3. Filesystem: %ProgramFiles%\Python<v>, %LocalAppData%\Programs\Python\Python<v>
   Crucially, we never fall back to running 'python.exe' from PATH
   on Windows — the WindowsApps stub at %LOCALAPPDATA%\Microsoft\
   WindowsApps\python.exe is a redirector that opens the Microsoft
   Store window if no Store Python is installed. Triggering that
   during boot would be terrible UX. Registry/filesystem probes
   never execute the binary.

2. Drop 3.14 from the supported version set. Several Hermes deps
   (notably pywinpty, which carries Rust crates like
   windows_x86_64_msvc) don't yet publish 3.14 wheels. With wheels
   missing, 'pip install -e .' falls back to building from sdist,
   which needs a Rust toolchain — users see 'could not compile
   windows_x86_64_msvc build script' on first run. install.ps1
   sidesteps this by pinning to 3.11 via uv; the desktop installer
   doesn't yet have the same uv-managed-Python pathway, so for now
   we accept 3.11/3.12/3.13 and tell winget to install 3.11 if
   none of those are present. Revisit when the wheel ecosystem
   catches up to 3.14 (~early 2026).

* feat(desktop): Cron, Profiles, usage analytics, and titlebar fixes

- Add Cron and Profiles sidebar routes with full CRUD-style flows and API wiring.
- Extend Command Center with auxiliary task overrides and a Usage panel (7d/30d/90d).
- Fix titlebar geometry for WSL/Windows (native overlay width, tool spacing).
- Remove stray merge conflict markers from pyproject.toml optional deps.

* fix(title-bar): position sidebar toggle button

* feat(desktop): composer queue — queue many, edit/delete/cancel-edit, Cursor-style

Press Enter while busy with a draft to queue it; with no draft to interrupt
and send the next queued turn. Auto-drains one queued turn each time the
session settles, same as Cursor. Queue persists across reloads so an
interrupted-and-queued turn isn't lost on refresh.

Each queued row supports edit-in-composer (with explicit Save/Cancel),
send-now (↑), and delete. Drain skips only the entry currently being
edited so the rest of the queue keeps flowing.

Queue dequeue is transactional — an entry only leaves the queue after
`prompt.submit` is accepted, so a rejected submit doesn't drop the turn.

Also shrinks the `[interrupted]` marker to a muted one-liner and drops
its assistant footer so it stops looking like a real reply.

* feat(desktop): add MCP settings and live subagent tree

Surface configured MCP servers in Settings with JSON edit/save and a gateway-backed reload action so users can manage tool servers without falling back to slash commands.

Track live subagent gateway events in a desktop store, show active subagent counts in the Agents statusbar item, and replace the Agents overlay stub with a live spawn tree for the active session.

Co-authored-by: Cursor <cursoragent@cursor.com>

* refactor(desktop): subagent overlay reads like a live transcript, not a dashboard

Strip the card chrome and rewire /agents to feel like peeking into the
child agent's stream:

- subagents store: single `stream` of typed entries (thinking/tool/progress/
  summary) replaces the parallel notes/thinking/tools arrays. Drop unused
  fields (toolsets, depth, apiCalls, reasoningTokens, sessionId).
- agents view: no OverlayCards, no boxed stream, no per-row borders. Goal +
  status pill + indented stream lines, full row width.
- Group root spawns into "Delegation N" sections when batch shape + spawn
  time match — hides task-index interleaving and makes hierarchy obvious.
- Sort tree by spawn time, then task_index. Step indicator is one colored
  pill (primary while running, emerald when done) inside the row, not a
  trailing pill that wrapped under the chevron.
- Tree picks up `subagent.start` (not only `spawn_requested`) and prunes
  delegate-tool fallback rows once native subagent events land for the
  session — fixes duplicate "Delegated task" rows alongside the real ones.

* feat(desktop): Esc closes every OverlayView-based overlay

Lift the keyboard handler into the shared OverlayView so Agents, Settings,
Command Center — and anything we build on top of it later — all dismiss on
Esc by default. Nested Radix dialogs stop propagation themselves, so a
modal opened inside an overlay (e.g. model picker inside Settings) still
closes the modal first, not the overlay underneath.

Drop the now-redundant Esc handlers in Settings (kept Cmd/Ctrl+P) and

* fix(desktop): drop numbered step pill on subagent rows

The pill was getting clipped at the overlay edge anyway. Just use the
status glyph (●/✓/✗/■/○) — the delegation header already conveys
"3 workers, 3 active", and order in the list implies which step you're
looking at.

* fix(desktop): drop noisy "returned N items / empty object" stub strings

When a tool returns nothing useful, the row should be silent — the title
("Search Files", etc.) already tells the user what happened. Counting the
fields in an opaque payload is engineer-noise.

`formatToolResultSummary` and `minimalValueSummary` now return '' for
empty arrays / records / unrecognized values; tool-fallback already hides
the detail section when its body is empty.

* refactor(desktop): subagent rows borrow chat tool patterns (fade-in, lucide glyphs, shimmer)

Pull the agents view closer to how chat tool blocks render:
- statusGlyph() returns the same lucide BrailleSpinner / CheckCircle2 /
  AlertCircle vocabulary as tool-fallback's statusGlyph
- Stream lines fade-in via useEnterAnimation (one-shot WAAPI), keyed per
  entry so streamed deltas settle in instead of popping
- Subagent rows fade in too, and pick up the existing data-slot=tool-block
  spacing rules between blocks
- Active stream line trails a BrailleSpinner instead of a hand-rolled
  pulsing rectangle
- Goal text drops FadeText (which forces nowrap); keep FadeText only for
  the single-line meta subtitle
- Running rows shimmer the title — same affordance the chat thinking row
  uses

* refactor(desktop): make /agents subagent-only, drop sidebar + dead sections

Activity rail and History stub were both noise. Strip the split layout,
sidebar, route enum, and the rail/stub helpers — the overlay is now just
the spawn tree, centered in a max-w-3xl column so it stops claiming the
whole screen for one section's worth of content.

* feat: update cron modals

* Add dedicated GUI log stream for dashboard debugging.

Capture dashboard and PTY websocket lifecycle failures in gui.log and expose it via hermes logs.

* Improve desktop runtime UX by surfacing inference readiness in gateway status and hardening WSL link opening.

This also stabilizes markdown code/table block spacing and adds root-install guards so desktop dev runs use a healthy workspace dependency tree.

* Log detailed GUI websocket failure metadata.

Capture richer reject/disconnect/send/parse context for dashboard gateway websocket flows so GUI connection failures are diagnosable from logs.

* Default dashboard startup logging to GUI mode.

Detect the dashboard subcommand during early CLI bootstrap so gui.log is attached from process start and GUI startup failures are always captured.

* Clean up gateway status conditionals and logging bootstrap mode detection.

Simplify nested dashboard gateway status branches for readability and use a concise first-subcommand check when selecting early GUI logging mode.

* add logging to nsis installer

* feat: glass ui pass

* fix(desktop): persist inline assistant errors across hydrate/resume

- Detect provider failure text arriving via message.complete
  (HTTP 4xx, "API call failed after N retries", Provider/Gateway
  error: ...) and persist as an inline assistant error instead of
  regular completion text, blocking the hydrate that was wiping it.
- preserveLocalAssistantErrors: merge by id so same-id hydrated
  messages keep their local error, and preserve the optimistic
  user+error pair as a unit (with tail-user dedupe).
- Hook all hydrate/resume writers (use-session-actions resume +
  fallback, hydrateFromStoredSession, syncSessionStateToView) into
  the merge so stale snapshots can't clobber a failed turn.
- Add error to chatMessagesEquivalent so the resume diff actually
  sees error-only changes and paints them.
- editMessage on a failed turn now submits a plain resend (no
  truncate_before_user_ordinal) and retries plainly on the
  "no longer in session history" race.

Style polish on touched files:
- Inline error: text-only treatment (no card).
- User stop / edit-composer send: shared Tabler IconPlayerStopFilled
  glyph + shared icon-button class slot for parity.

* feat(desktop): theme xterm with active light/dark mode

The right-sidebar terminal hardcoded a light palette, which read poorly
on the dark glass surface. Subscribe to `useTheme().resolvedMode` and
hot-swap `term.options.theme` so Shift+X (and any other mode change)
updates the terminal in place without tearing down the PTY session.

Dark mode uses xterm's built-in defaults (white fg/cursor + vivid ANSI
16) with just a transparent background so the glass shows through;
light mode keeps the existing hand-tuned overrides for legibility on a
bright surface.

* feat(sidebar): right-click + drag-reorder sessions and workspaces

- Wire right-click on session rows to open the same actions menu;
  suppresses the OS-native context menu so Windows stops looking awful.
- Share dropdown + context menu items via useSessionActions() driving
  a single declarative ItemSpec[]; render polymorphic over MenuItem.
- New shadcn ContextMenu primitive mirroring DropdownMenu styling.
- Restore drag-and-drop reordering for Agents (lost during the cwd
  cleanup) and add reordering of workspace groups via a right-side
  grab handle. Pinned reorder unchanged.
- Generic orderByIds<T> replaces the duplicated session/group orderers;
  useSortableBindings() hook collapses the two Sortable wrappers.
- cursor-pointer on every actionable element; cursor-grab on handles.
- KISS pass: baseName() helper, AGE_TICKS table, single WORKSPACE_PAGE
  constant, flatter SidebarSessionsSection render.

* feat(desktop): solarize the xterm palette in both light & dark

xterm's default ANSI 16 is tuned for dark and reads candy-bright on the
light glass surface (vivid cyans/greens). Ship the canonical Solarized
palette (Schoonover) for both modes — same 16 accents either way, only
fg/cursor swap between `base00/01` (light) and `base0/1` (dark), so a
prompt's colors look uniform across a Shift+X toggle.

Background stays transparent in both modes — Solarized's cream/slate
backgrounds would fight the glass.

* feat(desktop): virtualize chat thread + sidebar via TanStack Virtual

Replaces `use-stick-to-bottom` and per-row session rendering with
`@tanstack/react-virtual`, matching what Cursor uses.

Chat thread (`thread-virtualizer.tsx`):
- Natural-flow virtualization (padding spacers, not absolute items) so
  `position: sticky` on the human bubble still resolves cleanly against
  the scroller.
- Custom at-bottom anchor: pins when armed, disarms on user-driven
  upward scroll, re-arms at bottom, jumps on session switch +
  `thread.runStart`.
- Loading indicator and `--thread-last-message-clearance` move to a
  real `[data-slot=aui_composer-clearance]` node; drops the brittle
  `:nth-last-child(1 of …)` rule that can't fire reliably under
  virtualization.

Sidebar (`virtual-session-list.tsx`):
- Flat agents list virtualizes at >=25 rows; pinned and
  workspace-grouped paths stay direct-render.
- `SortableContext` keeps all IDs; only the window mounts; dnd-kit's
  `setNodeRef` is merged with `virtualizer.measureElement` so rows
  participate in both DnD hit-testing and TanStack measurement.

Drops `use-stick-to-bottom`. Streaming test gets a global
`offsetWidth/offsetHeight` stub so the virtualizer's viewport sizing
works in jsdom; the scroll-up-doesn't-pull-back invariant still passes.

* feat: more ui qa

* fix(desktop): trim sidebar terminal startup spacer

Drop zsh's initial spacer row before writing the first terminal prompt so new sidebar terminal sessions do not open with a selectable blank line.

* chore: uptick

* feat(desktop): thin installer + first-launch install.ps1 bootstrap

Converges the Windows packaged desktop installer onto a single canonical
install topology: drop the Electron shell only (~80MB instead of ~500MB),
clone Hermes Agent at a build-time-pinned commit on first launch via
install.ps1's stage protocol, and treat the resulting git checkout at
%LOCALAPPDATA%\hermes\hermes-agent\ as the canonical install location
(same path the CLI installer uses).  Future updates flow through the
existing applyUpdates() git-pull path.

Replaces the previous fat-installer architecture where the .exe bundled
a pre-staged hermes-agent source tree under resources/hermes-agent/ that
was then sync'd into ACTIVE_HERMES_ROOT at launch -- a complicated
factory-vs-active dance with several footguns (FACTORY_HERMES_ROOT
mismatch on path resolve, isGitCheckout guard regressions, pyproject
hash drift detection inside the sync loop).

Architecture overview
---------------------

  Build time
    apps/desktop/scripts/write-build-stamp.cjs writes
    apps/desktop/build/install-stamp.json with {commit, branch, builtAt,
    dirty}.  Honours $GITHUB_SHA / $GITHUB_REF_NAME in CI, falls back to
    `git rev-parse HEAD` locally.

    apps/desktop/scripts/stage-native-deps.cjs copies the runtime subset
    of @homebridge/node-pty-prebuilt-multiarch from the workspace-root
    node_modules into apps/desktop/build/native-deps/.  Workspace dedup
    hoists this dep to the root, out of reach of electron-builder's
    `files:`-restricted collector; staging gives us a deterministic
    path to extraResources.

    electron-builder ships both into resources/install-stamp.json and
    resources/native-deps/ respectively.

  Boot resolver (electron/main.cjs)
    Resolver order:
      1. HERMES_DESKTOP_HERMES_ROOT override
      2. SOURCE_REPO_ROOT (dev mode)
      3. ACTIVE_HERMES_ROOT git checkout WITH .hermes-bootstrap-complete
         marker -- the post-install fast path
      4. `hermes` on PATH (CLI-installed user adding the desktop)
      5. pip-installed hermes_cli via system Python
      6. bootstrap-needed sentinel -> hand off to runBootstrap

    Deletes the entire FACTORY_HERMES_ROOT / RUNTIME_MARKER /
    syncTreeExcludingVenv machinery (-200 lines).  The isGitCheckout
    guard that bit us in the install.ps1 PR is gone.

  First-launch bootstrap (electron/bootstrap-runner.cjs)
    1. Resolve install.ps1: prefer SOURCE_REPO_ROOT/scripts (dev), else
       download from GitHub raw at INSTALL_STAMP.commit (cached at
       HERMES_HOME\bootstrap-cache\install-<sha>.ps1).
    2. Fetch the stage manifest via install.ps1 -Manifest -Commit X
       -Branch Y.
    3. Iterate stages: install.ps1 -Stage <name> -NonInteractive -Json
       -Commit X -Branch Y per stage.
    4. On all stages green: write the .hermes-bootstrap-complete
       marker with {schemaVersion, pinnedCommit, pinnedBranch,
       completedAt, desktopVersion}.

    Per-run log to HERMES_HOME\logs\bootstrap-<ts>.log.  Cancellation
    via AbortSignal.  Manifest cache so retries don't re-download.

  Install overlay (src/components/desktop-install-overlay.tsx)
    Mounted alongside the existing onboarding overlay; flexbox card
    with header (static) + middle (scrollable) + footer (failure-only,
    static).  Subscribes to hermes:bootstrap:event IPC + resyncs from
    hermes:bootstrap:get on mount/reload.  Renders:
      - 14-stage checklist with per-stage state icons
      - Overall progress bar + current-stage spotlight
      - Auto-expanded installer-output panel on failure
      - "Copy output" button (full ring buffer + error to clipboard)
      - "Reload and retry" wired through hermes:bootstrap:reset to
        clear main.cjs's latched failure
    Synthetic empty-manifest event from main.cjs flips the overlay to
    'active' immediately so the slow install.ps1 download doesn't
    leave the user staring at the generic Preparing splash.

  Failure latching (main.cjs)
    bootstrapFailure module-scope variable holds the rejection after
    install.ps1 fails.  startHermes() throws the latched error
    immediately when set, bypassing the entire ensureRuntime +
    runBootstrap chain.  Without this, the renderer's ensureGatewayOpen
    retries would re-run install.ps1 in a 5-10 min hot loop while the
    user was still reading the failure overlay.  Cleared via
    hermes:bootstrap:reset on user-driven retry.

  Unsupported-platform overlay (1F)
    macOS / Linux packaged builds (no install.sh stage protocol yet)
    emit an unsupported-platform event with a copy-pasteable install
    command + docs URL.  Dedicated overlay branch with "Copy command"
    + "I've run it -- retry" buttons.

install.ps1 additions (Phase 1F.3 + 1F.5)
-----------------------------------------

  New -Commit and -Tag string params.  Precedence Commit > Tag >
  Branch.  Honoured by all three code paths (update / fresh clone /
  ZIP fallback), with archive URL selection that handles each
  ref-type variant.  Detached-HEAD checkouts intentionally -- they're
  pins, not branches the user pulls into.

  EAP=Continue wrap around the new pin-step git invocations.  `git
  fetch origin <commit>` writes the routine 'From <url>' info line to
  stderr; under the script's global EAP=Stop that terminates the
  script even though fetch+checkout succeed.  Matches the established
  pattern in Install-Uv, Test-Python, _Run-NpmInstall.

Backend fix (hermes_cli/web_server.py)
--------------------------------------

  CORS allow_origin_regex now accepts Origin: 'null'.  Packaged
  Electron loads index.html via file://; Chromium sets the WebSocket
  upgrade Origin header to the opaque origin 'null', which the old
  regex rejected with HTTP 403 before gateway_ws() ever ran.  This
  failure mode was masked in the older FACTORY_HERMES_ROOT
  architecture because the resolver often found an existing hermes
  on PATH with different binding behavior.

  Security maintained: localhost-only bind keeps cross-machine pages
  out; per-process session token still gates every authenticated
  /api/ endpoint regardless of Origin.

Desktop QoL
-----------

  DevTools is now enabled in packaged builds (F12 / Cmd+Opt+I).
  Field-debugging trade-off: tiny attack surface increase versus
  a much better support story when CSP / WS / theme issues surface.

  NSIS prereq-check page deleted (-767 lines).  The standard
  Welcome -> License -> Directory -> InstallFiles -> Finish wizard
  now installs without custom Python/Git/ripgrep detection -- those
  prereqs are install.ps1's job at first launch.

Test infrastructure (Phase 1G)
------------------------------

  apps/desktop/scripts/test-desktop.mjs rewritten as a cross-platform
  bundle validator (was darwin-only and asserted on dead factory-
  payload paths):
    NEGATIVE: hermes_cli/main.py is NOT shipped (regression guard)
    POSITIVE: install-stamp.json carries a real commit + branch
    POSITIVE: node-pty native deps shipped under resources/native-deps
    POSITIVE: renderer dist/index.html reachable (asar or unpacked)
  New nsis mode and npm run test:desktop:nsis script.

Validated end-to-end on clean Win10 VM
--------------------------------------

  Confirmed: NSIS installer drops Electron shell, app launches,
  install overlay shows progress, install.ps1 clones the pinned
  commit, 14 stages run to completion, marker written, backend
  spawns, WebSocket connects, onboarding overlay asks for API key,
  main UI loads, integrated terminal works.

  Failures handled: bootstrap stays failed (no hot-loop retry),
  "Copy output" gives actionable transcript, "Reload and retry"
  explicitly re-runs install.ps1.

What's deferred
---------------

  - MSIX wrapping (Phase 2): same Electron .exe under MSIX manifest
    with runFullTrust, signed and submitted to Microsoft Store.
  - install.sh stage protocol parity (Phase 2): once shipped, the
    unsupported-platform overlay becomes drive-it-yourself and
    macOS/Linux packaged installers gain feature parity with Windows.

* feat(desktop): persistent terminal pane + fullscreen takeover

Adds a VSCode-style "focus terminal" toggle to the right sidebar's Terminal
tab that takes over the chat pane area without unmounting the shell. The
xterm host is mounted once at the layout root and CSS-overlayed onto
whichever <TerminalSlot /> is currently active, so the PTY session,
scrollback, selection, focus, and WebGL renderer survive every toggle.

Also:
- WebGL renderer (matching dashboard ChatPage) so Hermes' TUI skins paint
  faithfully instead of muting through xterm's default DOM renderer
- File drag/drop from the project tree or OS into xterm — paths are
  shell-quoted (zsh/bash/pwsh/cmd) and written straight into the PTY
- Solarized dark canvas with brights promoted to real accent variants
  (Schoonover's UI-gray brights washed out every TUI accent)
- Strip NO_COLOR/FORCE_COLOR/COLORFGBG/TERM=dumb leaking from non-tty
  parents (CI runners, Cursor's agent shell) so the embedded shell gets
  truecolor regardless of how Electron was launched
- rAF-debounced ResizeObserver — running fit.fit() synchronously during
  sibling pane transitions crashed the WebGL texture-atlas rebuild

* fix(install.ps1): strip UTF-8 BOM regression that broke 'irm | iex'

The canonical install flow

    irm https://raw.githubusercontent.com/.../scripts/install.ps1 | iex

fails on PowerShell 5.1 with a cascade of 'The assignment expression
is not valid' errors at every param() default value:

    [string]$Branch = 'main',
                      ~~~~~~
    The assignment expression is not valid. The input to an assignment
    operator must be an object that is able to accept assignments...

Root cause: scripts/install.ps1 carries a UTF-8 BOM (0xEF 0xBB 0xBF)
as its first three bytes. 'irm' returns the response body as a string;
on PS 5.1 the BOM survives into that string as a leading \ufeff
character. 'iex' then evaluates the string and PS's parser chokes
on the invisible character before param() -- error recovery proceeds
into the body but every assignment is reported as broken.

This was the exact failure mode the install.ps1 hardening pass (PR
#27224) deliberately fixed by stripping the BOM and ensuring the
file body is pure ASCII. Commit 4279da4db ('fix(windows): make
PowerShell installer parse in 5.1') re-introduced the BOM later,
unintentionally undoing the irm|iex compatibility fix; the merge
that brought it into bb/gui carried it forward.

Fix: strip the three BOM bytes. File body is verified pure ASCII
(any-byte > 127 returns false), so PS 5.1 with no BOM falls back to
Windows-1252 decoding which is identical to ASCII for our content.
Both install paths now work:
  - 'irm ... | iex' (canonical CLI)
  - 'powershell -File install.ps1' (programmatic / desktop bootstrap)

* install.ps1: detect ARM64 Windows reliably for Node and Git stages

Add a Get-WindowsArch helper that reads Win32_Processor.Architecture
via CIM (invariant to PowerShell host bitness) with PROCESSOR_ARCHITEW6432
fallback. Use it in:

- Install-Git: previously only triggered the arm64 PortableGit asset
  when invoked from a native-ARM64 PowerShell host. WoW64 / emulated
  x64 hosts (the default powershell.exe on Windows-on-ARM) saw
  PROCESSOR_ARCHITECTURE=AMD64 and fell through to the x64 PortableGit
  build, leaving ARM64 users on emulated Git for Windows.

- Test-Node: previously hardcoded the Node download to win-x64 on any
  64-bit OS, so ARM64 users always got x64 Node under Prism emulation
  even though Node ships an arm64 build for Windows. The winget
  fallback now also passes --architecture arm64 on ARM64.

Python remains x86_64 by design: uv intentionally prefers
windows-x86_64 cpython on ARM64 hosts for ecosystem (wheel)
compatibility (see astral-sh/uv#19015).

* install.ps1: harden Install-SystemPackages against winget msstore failures

The previous winget invocation discarded stdout/stderr and trusted no
signal at all -- not the exit code (winget exits 0 even when it bails
"please specify --source"), not output (sent to Out-Null), not the
catch handler (winget returning 0 means no exception fires). The only
trust signal was a post-install Get-Command rg / Get-Command ffmpeg
check, which would also miss the package because %LOCALAPPDATA%\
Microsoft\WinGet\Links (where winget puts command aliases) is added to
PATH by AppExecutionAlias machinery only in fresh shells. End result on
machines where the msstore source has a cert problem (0x8a15005e --
common on Windows-on-ARM and some corporate networks): silent failure,
no log, no breadcrumb, and the user is told the install succeeded.

Specifically:

- Pin --source winget on every winget install call. Defeats the broken-
  msstore-source path. We ship nothing from msstore so this is safe and
  forward-compatible.

- Add --exact --id for a tighter package match.

- Capture each winget invocation's combined stdout/stderr + exit code to
  %TEMP%\hermes-winget-<pkg>-<n>.log instead of Out-Null. On the happy
  path the log is deleted after the post-install check confirms the
  binary is on PATH; on failure the log is kept and its path is named in
  a Write-Warn so the user has something to grep.

- Refresh PATH to include %LOCALAPPDATA%\Microsoft\WinGet\Links in
  addition to the User/Machine env-var hives, so Get-Command sees newly-
  installed winget aliases in the same process.

- No behavior change on the happy path. Same Write-Info/Success/Warn
  cadence, same fallback order (winget -> choco -> scoop -> manual),
  same $script:HasRipgrep / $script:HasFfmpeg outputs.

Verified end-to-end on a real Snapdragon ARM64 Windows host: ripgrep
uninstalled, stage re-run, [OK] ripgrep installed in 1.4s, ok:true.

* desktop: swap node-pty fork for upstream microsoft/node-pty 1.1.0

The previous dependency, @homebridge/node-pty-prebuilt-multiarch@0.13.1,
publishes no win32-arm64 prebuilds on its v0.13.x line, and its v0.14.x
betas (which do add an arm64 Windows build) ship no electron-vXXX-win32-
arm64 prebuilds at all -- so packaged Electron 40 builds (NMV 143) would
fail at runtime even on a successful npm install. Net effect: the
desktop's integrated terminal was unbuildable on Windows-on-ARM, in
both dev (npm install fails: 404 fetching the node-vXXX-win32-arm64
prebuilt) and packaged builds (no Electron-ABI prebuilt exists).

The homebridge fork was originally created because upstream node-pty
shipped no prebuilds at all. That hasn't been true since node-pty@1.0
(April 2024), which:

- bundles prebuilts for mac (arm64+x64) and Windows (arm64+x64) directly
  inside the npm tarball -- no GitHub-Releases fetch, no missing-binary
  failure mode
- uses N-API (node-addon-api) for ABI stability across Node and Electron
  major versions, so the same pty.node binary loads under Node 22 (dev)
  and Electron 40+ (packaged) without per-ABI rebuilds
- is what VS Code, Hyper, and Theia actually ship

API surface is identical (spawn / onData / onExit / write / resize /
kill) -- no call-site changes needed.

Specifically:

- apps/desktop/package.json: replace the @homebridge fork with
  node-pty@1.1.0 (exact pin). Widen `asarUnpack` from `["**/*.node"]`
  to also unpack `**/prebuilds/**`, because node-pty ships runtime-
  execed helpers alongside its .node files (darwin spawn-helper has no
  extension and would not be matched by `**/*.node`; conpty.dll,
  OpenConsole.exe, winpty.dll, winpty-agent.exe on Windows are also
  exec'd at runtime and cannot live inside asar).

- apps/desktop/electron/main.cjs: update both require() strings to
  match the new package name and the new staged path under
  resources/native-deps/node-pty/.

- apps/desktop/scripts/stage-native-deps.cjs: point at node_modules/
  node-pty. node-pty's prebuilts live under prebuilds/<plat>-<arch>/
  (not build/Release/), so update the include glob to copy that dir.
  Per-arch staging keeps the resource bundle small (target arch comes
  from npm_config_arch when electron-builder cross-builds, else
  process.arch). Explicitly enumerate file types in the prebuilds glob
  so the ~25 MB of .pdb debug symbols that prebuild-install bundles
  for Windows crash analysis don't bloat the installer (29 MB -> 2.6 MB
  staged on win32-arm64). Re-assert +x on the darwin spawn-helper
  defensively, since a stripped mode bit would manifest as a silent
  ENOENT at first pty.spawn().

- apps/desktop/scripts/test-desktop.mjs: update expectedNativeDepPaths()
  and its assertion site to look at prebuilds/<plat>-<arch>/ instead of
  build/Release/. Add an explicit spawn-helper-exists check on darwin
  so a regression in the asarUnpack glob would fail loudly in CI rather
  than at first PTY spawn.

Trade-off: Linux end-users lose prebuilts and fall back to building
node-pty from source on `npm install`. Acceptable because Hermes
ships no Linux desktop builds (desktop-release.yml matrix is mac + win
only, package.json declares no `linux` target), and Linux developers
hacking on the desktop already need a C++ toolchain for the rest of
the stack.

Verified on Windows 11 ARM64 (Snapdragon):
  npm install                                          -> exit 0
  node -e "require('node-pty').spawn(...)" round-trip  -> OK
  stage-native-deps                                    -> 27 files, 2.6 MB
  load from staged tree (simulates packaged fallback)  -> ConPTY
                                                           round-trip OK

* desktop+gateway: harden Slack socket recovery and Windows restart dedupe (#28873)

* desktop+gateway: harden Slack socket recovery and Windows restart dedupe

Fix Slack Socket Mode reliability by adding a watchdog/reconnect path so silent socket task drops no longer leave the adapter stuck. Harden Windows gateway lifecycle by avoiding desktop-binary path collisions, making gateway PID scans case/extension tolerant, and reusing in-flight restart actions to prevent duplicate gateway spawns.

* test(slack): add Socket Mode watchdog/reconnect behavioural coverage

Drive the new Slack Socket Mode self-healing logic through a fake AsyncSocketModeHandler so we can simulate the P0 silent-hang failure mode (task exit, transport disconnected, intentional shutdown, concurrent reconnect attempts) without touching real Slack.

* fix(slack,desktop): address Copilot review on watchdog races and path normalization

- connect(): explicitly cancel + await the prior socket watchdog before flipping _running, so an old monitor cannot exit between teardown and respawn (Copilot #1)
- _socket_watchdog_loop: wrap the body in try/except + add a done-callback that respawns on unexpected crash, so a transient bug cannot permanently disable self-healing (Copilot #2)
- normalizeExecutablePathForCompare: use the resolved path for realpathSync so non-string inputs cannot leak through (Copilot #3)
- Add tests for crash-recovery and atomic watchdog replacement across reconnects

* fix(slack): tighten connect() error path and clarify watchdog test intent

Address Copilot review round 2.

- connect(): wrap _start_socket_mode_handler/_ensure_socket_watchdog in a focused try/except so any failure rolls back partially-started handler/task state and leaves _running=False, ensuring the platform lock is always released by the outer finally
- Defer _running=True until after the handler is actually started so the watchdog observes a live socket task immediately and never spins against a half-built adapter
- Rename test_watchdog_self_restarts_after_unexpected_crash to test_watchdog_cancellation_does_not_respawn (matches what it actually asserts) and add test_watchdog_unexpected_exit_respawns_via_done_callback that drives a real RuntimeError through _on_socket_watchdog_done and verifies a fresh task replaces the crashed one

* fix(web_server): serialize action spawn check+store under a threading lock

Address Copilot review round 3.

FastAPI runs sync handlers on its threadpool, so two near-simultaneous /api/gateway/restart (or /api/hermes/update) requests could both observe "no live process" in _spawn_hermes_action's poll-based dedupe and double-spawn. Add a module-level _ACTION_SPAWN_LOCK around the entire check + Popen + _ACTION_PROCS store sequence so the dedupe is atomic across threads.

* fix: address Copilot review round 4

- slack.disconnect(): mirror connect()'s defensive cleanup — catch the broad Exception path on watchdog await so handler shutdown and lock release still run if the watchdog raised before cancellation took effect
- web_server._spawn_hermes_action: wrap subprocess.Popen in try/except so a missing executable / permission error closes the log file handle, writes a failure marker, and re-raises instead of leaking a file descriptor
- gateway._scan_gateway_pids: drop the over-broad "hermes.exe --profile" / "hermes.exe -p" patterns that would match any Hermes CLI subcommand using a profile flag (e.g. `hermes.exe --profile foo dashboard`); rely on the "hermes.exe gateway" + "hermes-gateway.exe" tokens instead
- tests: tighten _fake_create_task to assert coroutine input and return a real asyncio.Task that stays pending until pytest teardown, and update the three callsites whose mocked AsyncSocketModeHandler.start_async returned a non-coroutine value

* fix(slack): reset multi-workspace state on reconnect

Address Copilot review round 5.

connect() is reentrant (gateway restart, in-process reconnect), but it was leaving _bot_user_id / _team_clients / _team_bot_user_ids populated from the previous session. A reconnect that rotated the primary token or dropped a workspace would silently keep the stale bot user id and stale workspace client maps, leading to dispatch against gone workspaces.

Clear these three pieces of state right after _stop_socket_mode_handler() and before the auth_test loop, then let the loop repopulate from the current tokens. Add test_reconnect_refreshes_multi_workspace_state to lock it in.

* nix: package apps/desktop as .#desktop (#28964)

Adds nix/desktop.nix building the Electron renderer with buildNpmPackage
and wrapping nixpkgs' electron binary.  Reuses .#default by setting
HERMES_DESKTOP_HERMES to its hermes binary, so the desktop's resolver
picks up the fully-wired nix hermes (venv, bundled skills/plugins,
runtime PATH) without reimplementing agent resolution.

- nix/desktop.nix: renderer + electron wrapper
- nix/hermes-agent.nix: finalAttrs form, exposes hermesDesktop in passthru
- nix/packages.nix: exposes .#desktop + adds to fix-lockfiles
- apps/desktop/package-lock.json: standalone hermetic lockfile

nix build .#desktop && nix run .#desktop both clean.

* fix(desktop): probe steps 4 & 5 of resolveHermesBackend before trusting

A user-reported failure on Windows-on-ARM: a pre-installed Python 3.13
on PATH makes findSystemPython() succeed, so resolveHermesBackend
returns a backend pointing at it -- but hermes_cli isn't in that
interpreter's site-packages. The spawn dies with ModuleNotFoundError
and the user sees a dead GUI instead of the first-launch installer.

Same shape can hit step 4 (existing `hermes` on PATH) when a stale
shim survives a partial uninstall.

Add cheap exit-code probes -- `python -c "import hermes_cli"` for
step 5, `<hermes> --version` for step 4 -- and fall through to step 6
(bootstrap-needed) on failure. install.ps1 then runs as if on a clean
box and the venv gets built.

Probes live in a standalone electron/backend-probes.cjs module so they
can be unit-tested with node --test, same pattern as bootstrap-platform.cjs
and hardening.cjs. New test file wired into test:desktop:platforms.

* test(desktop): allow `node-pty` bare-require in packaged entrypoints

Pre-existing failure on bb/gui since c858484b4 swapped the node-pty
fork for upstream microsoft/node-pty 1.1.0. main.cjs intentionally
bare-requires node-pty (it's hoisted by workspace dedup in dev, and
staged to resources/native-deps via scripts/stage-native-deps.cjs +
extraResources for packaged builds, with a try/catch fallback at
line ~38). The allowlist hadn't been updated to match -- same shape
as `electron`, which was already allowed.

* chore(deps): refresh root lockfile for dashboard @nous-research/ui 0.14.0

apps/dashboard/package.json was bumped to @nous-research/ui 0.14.0 (+
flag-icons ^7.5.0, motion ^12.38.0) but the root package-lock.json was
never refreshed. Running `npm install` from the repo root now
materialises 0.14.0's transitive closure (launder, bumps for
@nanostores/react, nanostores, sanitize-html, tailwind-merge).

No code changes; purely a lockfile catch-up so fresh checkouts on bb/gui
get a working dashboard install.

* chore(desktop): bump version to 0.0.1

First non-placeholder version so electron-builder's artifactName template
produces `Hermes-0.0.1-win-x64.exe` instead of the obviously-unreleased
`Hermes-0.0.0-...`. No release process yet; this just stops the artifact
filename from telling users "you got a debug build."

Bumped in three slots that all carry the desktop app's version:
- apps/desktop/package.json (source of truth)
- apps/desktop/package-lock.json (per-app lockfile, kept for CI parity)
- root package-lock.json's apps/desktop workspace entry

Identity-of-build for first-launch bootstrap continues to come from
build/install-stamp.json (commit SHA + builtAt), unchanged.

* fix: fs icon color

* perf(desktop): cut per-keystroke layout + listener churn in chat composer

Empirical work via CDP harnesses under apps/desktop/scripts/ (see
profile-typing-lag.md):

  jsListeners growth (per round of 200 chars + GC):
    before: +35  (verified leak — listeners stuck after 1st trigger popover use)
    after:  +0

Four narrow edits in src/app/chat/composer/index.tsx:

1. Drop the per-keystroke `editorRef.current.scrollHeight` read used to
   decide composer expansion. Replace with `draft.length > 60` heuristic;
   the existing ResizeObserver still catches edge cases. `scrollHeight`
   is a forced-layout call and was firing on every char until the first
   wrap.

2. Bucket measured composer height to 8px before writing
   `--composer-measured-height` / `--composer-surface-measured-height`
   on `documentElement`. Without this, the editor grows ~1px per char,
   setProperty fires every keystroke, computed style is invalidated tree-
   wide.

3. Remove the dead `$composerDraft` two-way sync. Nothing outside the
   composer subscribed to that atom (verified via grep). Two useEffects
   on `[draft]` were pushing draft→atom and atom→aui per keystroke for
   no consumer. Also drop the per-keystroke
   `reconcileComposerTerminalSelections` call; it was pruning stale
   labels for `terminalContextBlocksFromDraft`, but that helper already
   ignores labels not in the current submitted text, so pruning per
   keystroke was just bookkeeping.

4. `refreshTrigger` fast-bails when the draft contains neither `@` nor
   `/`. Previously `textBeforeCaret(editor)` ran on every input/keyup
   regardless; `range.toString()` inside is O(n) over draft length.

Synthetic typing latency p50/p90/p99 is similar before vs after on a
freshly-loaded session (Blink can already handle ~30cps typing into a
contentEditable on its own); the real win is the listener leak being
gone and the global computed-style invalidations dropping ~8× when the
composer is sitting at a fixed height row.

The `Enter → stall` follow-up (see profile-typing-lag.md §"Submit /
TTFT stall") is unmeasured here — needs a throwaway session because
the harness fires a real prompt. Not blocking this commit.

* perf(desktop): cut FadeText forced layouts during streaming

The slowest user-felt path is typing into the composer while the
assistant is streaming. Profile (scripts/profile-under-stream.mjs):

  FadeText measureOverflow self time:  35.8 ms → 18.1 ms  (-50%)
  total active CPU during 7s window:   ~150 ms → ~50 ms

Two changes in src/components/ui/fade-text.tsx:

1. Drop the `useEffect([children])` that re-ran `measureOverflow`
   (reads scrollWidth + clientWidth — forced layout) on every parent
   re-render. `useResizeObserver` already fires the same callback on
   mount and whenever the host span's box size changes; that covers
   the only case where overflow state can legitimately change. The
   previous explicit useEffect was a forced-layout flush on every
   parent render, which during streaming meant every token tick.

2. Wrap the component in `memo` with a custom comparator that
   short-circuits the entire render when scalar string `children` and
   the className/fadeWidth/style props are unchanged. The hot path
   was tool-fallback's title chips being re-rendered by parent
   streaming updates even though their text was stable; memo+
   comparator skips that.

Also adds two harness scripts under apps/desktop/scripts/:
  - latency-under-stream.mjs (key→paint latency while a turn streams)
  - profile-under-stream.mjs (CPU profile while a turn streams)

Updates profile-typing-lag.md with the streaming numbers and confirms
the Enter→paint submit path is already fast (≤320ms on the populated
session; the 2s "stall after Enter" the user noticed once was a
one-time cold-start, not reproducible at the UI layer).

I'd guess the felt jank in real use is fast-burst typing during a
long-form streaming reply (code blocks + markdown lists multiply the
per-token render cost). The CPU savings here scale linearly with
token volume.

* chore(desktop): drop diag scratch scripts no longer needed

* docs(desktop): correct leak-typing numbers on a real session

Re-ran the leak harness on a populated session (Phaser thread) for both
unpatched and patched builds. The original 'listener leak' was transient
warm-up cost, not a steady-state leak — both versions show 0 listener
growth/round in steady state.

The load-bearing number is forced layouts per character:
  unpatched (HEAD~2):  7.02 layouts/char
  patched   (HEAD):    2.35 layouts/char  (3× fewer)

The patches reduce per-char forced-layout work to Blink's natural floor.
Document node count and heap are flat in both builds.

* perf(desktop): fix "Enter jumps up" on long threads

User reported: after pressing Enter on a long thread, the view jumps up
— the just-submitted message disappears below the fold. Confirmed via
apps/desktop/scripts/measure-jump.mjs:

  before:  distFromBottom 0 → 49.5px, sticks there permanently
  after:   distFromBottom 0 → ~0 (worst case 4px for one frame)

Root cause in useThreadScrollAnchor (thread-virtualizer.tsx):

1. The sticky-bottom logic disarmed on any scroll event where
   `scrollTop < lastTopRef.current`. That check can't distinguish a
   user scrolling up from a programmatic `pinToBottom` write that
   the browser clamped short of bottom (because content also grew in
   the same frame, so `scrollTop = scrollHeight` lands at
   `scrollHeight - clientHeight` for the OLD scrollHeight, which is
   now below the NEW scrollHeight). Result: sticky-bottom disarmed
   permanently on the user's first submit.

2. There was no synchronous pin tied to React's commit phase. By the
   time the ResizeObserver fired and re-pinned, the user had already
   seen ~50ms of "message below the fold" — visually that reads as the
   view jumping up.

Fix:

- `programmaticScrollPendingRef` counter tracks scroll events we
  expect to be ours (one per `pinToBottom` write). The scroll handler
  skips the disarm check when consuming a pending tick, keeps the
  arm bit true, and re-pins synchronously if the browser clamped us
  short of bottom. A depth cap (8) breaks runaway loops in
  pathological streaming-burst layouts.

- `useLayoutEffect` on `groupCount` increase pins BEFORE the browser
  paints, eliminating the visible ~50ms window between optimistic
  user-message insert and the RO/scroll-event chain firing.

Verified on the long Cloud Shadows thread (7-8 turns, ~11k px tall):
all three repro runs now hold within 0–4 px of bottom across the
post-Enter transition. Submit latency unchanged (paint 77–107 ms),
streaming-typing latency unchanged.

Also adds three debug harnesses:
  - measure-jump.mjs   — sample thread scroll across Enter
  - probe-thread.mjs   — dump current thread / scroll state
  - diag-jump.mjs      — intercept scrollTop + RO + mutations across Enter

* perf(desktop): rate-limit thread auto-pin during streaming

Follow-up to the Enter-jump fix. The first version did a synchronous
re-pin loop inside the on-scroll handler when the browser clamped our
`scrollTop = scrollHeight` write short of the new bottom; that gave a
tight 4 px visible jump on Enter, but during streaming the
ResizeObserver fires many times per second as content grows, and each
RO callback re-entered the pin loop. CPU profile showed
`Virtualizer.getMaxScrollOffset` climbing to 22 ms self over a typing-
during-streaming window — the sync re-pin path was paying tanstack-
virtual's recompute cost ~3× per token.

Re-architect:

- RO callback coalesces to one pin per animation frame. Streaming-rate
  RO bursts now cost the same as a single per-frame pin.
- The on-scroll programmatic-counter guard remains (it's what prevents
  the false-disarm bug when the browser clamps a write). It no longer
  does sync re-pins; the next RO/rAF will catch up.
- The useLayoutEffect on groupCount (the path that fires on user
  submit / new turn arrival) ALSO schedules one rAF pin in addition to
  the synchronous pin. This catches the case where React mounts the
  new message in a second commit (after our layout effect ran), which
  grows scrollHeight again. Two pins instead of a tight loop, paid only
  once per turn change.

Net effect on the Cloud Shadows long thread:

  enter-jump transient:   12–20 px for 1 frame (was 49 px permanent)
  CPU during stream+type: `getMaxScrollOffset` dropped out of top-5
                          self-time list
  typing-during-stream:   p50 ~10 ms paint, p99 ~20 ms (1 frame),
                          occasional 40 ms+ outliers during burst
                          token arrivals

Also adds scripts/profile-long-stream.mjs: 20-second streaming profile
with per-500ms FPS histogram + content-length tracking, so we can see
whether streaming render cost grows with message length (it doesn't —
sustained 60 fps).

* perf(desktop): use textContent for trigger precondition

Replace composerPlainText() call inside refreshTrigger's no-trigger
fast-bail with a textContent check. textContent is a browser-native
flat traversal; composerPlainText walks recursively with chip-aware
logic. We only need to know if @ or / appears; either way the trigger
char will be in textContent because chips contain @ in their refText.

Profile shows composerPlainText was ~18ms self over a 12s typing-during-
stream window, called from refreshTrigger on every keystroke. Most of
that was the precondition check (the trigger detection path is the
slow path but only runs when a trigger char is present).

* chore(desktop): synthetic-stream perf harness + scripts

Drops the React `<Profiler>` approach (no-op because Vite is currently
serving the production React build) in favor of an externally-observable
measurement stack: rAF frame intervals, `PerformanceObserver({entryTypes:
['longtask']})`, and a `MutationObserver` on the live streaming message.

Adds a synthetic stream driver — `window.__PERF_DRIVE__.stream({...})` —
that pushes tokens through the live `$messages` atom at a controlled rate,
so the assistant-ui runtime, incremental repository, and Streamdown
markdown pipeline see the same workload they'd see during a real LLM
stream, without the LLM cost.

The driver lives in `src/app/chat/perf-probe.tsx`; `main.tsx` side-imports
it under `import.meta.env.MODE !== 'production'` so it tree-shakes out of
prod builds. (Using `MODE` rather than `DEV` because our Vite setup
currently reports `DEV=false` even under `vite dev` — see the dev-build
note in `profile-typing-lag.md`.)

Scripts:
  - measure-synthetic-stream.mjs  drive synthetic + record frame/longtask/mutation
  - profile-synth-stream.mjs      CPU profile + top self-time during synthetic
  - measure-real-stream.mjs       same harness, real LLM stream
  - profile-real-stream.mjs       CPU profile bracketing the real stream window
  - eval.mjs / reload.mjs         small CDP helpers

A real-LLM measurement on Cloud Shadows (gpt-4o-mini, 39 s window) showed
12 longtasks in the same 75-127 ms range the synthetic predicted, so the
synthetic is a faithful proxy.

* perf(desktop): memo FadeText so it skips re-renders when text unchanged

FadeText is used 110+ times inside `tool-fallback.tsx` on a tool-heavy
thread. During streaming each parent re-render previously triggered the
component's `useEffect([children])`, which forced a `scrollWidth` layout
read even when the title text was unchanged. The `useResizeObserver` was
already covering the genuine resize case, so that effect was strictly
redundant work.

Drops the effect and wraps the component in `React.memo` with a custom
comparator that field-compares `className`, `fadeWidth`, and `style`,
plus identity-compares `children` (scalar fast-path; correct for JSX
nodes too since a new node should force a re-render).

Verified via temporary render counter on the 34 MB
`session_20260514_215353_fe0ac8` thread (110 FadeText instances): a
2 s synthetic stream went from ~11k FadeText render calls to 122 —
roughly one render per truly-new instance instead of one per parent
commit per instance.

Doesn't move the longtask needle on its own (Streamdown's markdown
re-parse dwarfs it) but eliminates a steady CPU floor and a class of
forced layouts during streaming. Profile-typing-lag.md documents the
full investigation, including the remaining Streamdown cost as the
real source of the perceived "5 fps moment" hitches.

* perf(desktop): memoize MarkdownText plugins to stop churning Streamdown

The inline `plugins={{ math: mathPlugin, ...(isStreaming ? {} : { code }) }}`
on `<StreamdownTextPrimitive>` constructed a new object literal on every
parent render. That broke `<Streamdown>`'s outer memo and forced its
internal `rehypePlugins` / `remarkPlugins` array useMemos to rebuild,
which propagates a new identity into every `<Block>` and defeats Block's
memoization for stable historical blocks.

After memoizing on `[isStreaming]` (the only real dimension of variance),
CPU profile during a 5 s synthetic stream on the 34 MB session shows
`parser` self-time dropping out of the top 10, `compile` cut roughly in
half, and `bn$1` / `m$1` (micromark internals) leaving the top entries.

Doesn't move the visible longtask count on its own — Streamdown's
per-Block parse cost still dominates whenever the last block's content
changes — but it removes a class of unnecessary re-parses for historical
blocks during streaming. See `scripts/profile-typing-lag.md` for the
full investigation.

* perf(desktop): floor assistant-text flush gap to 33ms for predictable batching

`scheduleDeltaFlush` previously coalesced via `requestAnimationFrame`
only. The "at most one flush per frame" guarantee that gives you is fine
for fast streams (>~80 tok/sec) where multiple tokens arrive within a
single frame, but breaks down at typical LLM token rates (30-80 tok/sec)
where each token arrives slower than the rAF cadence and triggers its
own React commit + Streamdown markdown re-parse.

Track `lastFlushAt` and require at least 33 ms between two flushes.
React 18+ auto-batching probabilistically already collapsed some of
these, but the floor makes it deterministic.

A/B on the 34 MB session, 300 tokens at 50 tok/sec (markdown chunks):

| | avgFps | p99 frame | LTs / 5 s | max LT |
|---|---|---|---|---|
| no floor (current rAF) | 54.0 | 38 ms | 2.0 | 145 ms |
| 33 ms floor (this PR) | 54.3 | 41 ms | 1.7 | 110 ms |

`inter-mutation` p50 also tightens from 22-28 ms to a clean 33 ms,
which is the expected signature of a deterministic floor. Doesn't fully
solve the user's perceived hitches — Streamdown's per-Block parse cost
when the last block grows past ~2 k chars is still the elephant — but
it consistently shaves the worst-case longtask and makes the streaming
cadence visibly steadier.

Also threads a matching `flushMinMs` option through the synthetic
stream driver in `perf-probe.tsx` + `scripts/measure-synthetic-stream.mjs`
so the harness can A/B both regimes without spending LLM credits.

See `scripts/profile-typing-lag.md` for the full investigation.

* perf(desktop): useDeferredValue for streaming markdown so parses don't block input

Streamdown's per-Block parse cost grows with the live tail's length and
is unavoidable inside the block-memo pattern (industry standard, see
findings doc). The fix is to stop having that work block the main thread.

`<DeferStreamingText>` is a 12-line wrapper that reads message-part state
via `useMessagePartText`, runs it through `useDeferredValue`, and
re-publishes via assistant-ui's `<TextMessagePartProvider>`. The inner
`<StreamdownTextPrimitive>` reads the deferred value through the normal
`useMessagePartText` hook — no fork, no internal-path imports, fully on
assistant-ui's public API. React's concurrent scheduler then:

  - abandons in-flight deferred renders when a newer token arrives, so
    intermediate states get skipped under fast streams
  - deprioritises the markdown render when the main thread has urgent
    work (typing, scroll), so input stays responsive even while a
    100ms parse is queued

Streamdown already uses `useTransition` for its block-array setState;
this lifts the deferral up to the consumer boundary so it covers the
whole pipeline (preprocess → split → repair → parse → render).

A/B on the 34 MB session, 300 tokens at 50 tok/sec, markdown chunks
(four trials each, with the 33ms flush throttle on for both):

| | avgFps | p99 frame | LTs/5s | max LT | typing-while-stream p95 |
|---|---|---|---|---|---|
| pre  | 54.3 | 41 ms | 1.7 | 110 ms | ~17 ms |
| post | 58.5 | 31 ms | 2.0 | 117 ms | 14-18 ms |

Longtask count + max LT unchanged — useDeferredValue doesn't reduce
CPU, only its priority. The avgFps lift and p99 frame drop are the
proof that the existing CPU is no longer blocking 60 fps cadence. One
clean run logged MUTATIONS=0 — React skipped every intermediate text
state and only committed the final one (textbook deferred-value
behaviour).

The actually-reduce-CPU path is replacing the parser with a state
machine like Flowdown — left for a future PR; see
`apps/desktop/scripts/profile-typing-lag.md` for the full investigation.

* feat(desktop): add hermes gui launcher

* feat(desktop): launch packaged gui builds by default

* bump gui version to 0.0.2

* fix(dashboard): allow file:// origin on loopback WS + diagnostic logging

Upstream commit 2e66eefbc ("fix(dashboard): validate WebSocket Host
and Origin") added a WebSocket Host/Origin guard to block DNS
rebinding against the dashboard.  The guard rejects any Origin whose
scheme is not http/https or whose netloc is empty — which includes
Electron's renderer Origin: file:// when the desktop app loads its
bundle from disk in production mode.

That makes the bb/gui Electron desktop unable to open the gateway
WebSocket against the embedded backend on Windows / macOS prod
builds.  The renderer reports "Desktop boot failed" and the backend
logs:

  WARNING hermes_cli.web_server: gateway-ws reject
      peer=127.0.0.1:NNNN reason=non_loopback_or_bad_origin
      bound_host=127.0.0.1 close_code=4403

DNS-rebinding requires a DNS-resolvable hostname; file:// has no
host component and therefore cannot be the attack vector this guard
exists to block.  When bound to a loopback interface (127.0.0.1 /
::1 / localhost), accept file:// origins so desktop wrappers can
attach.  Non-loopback binds (operator opted into network exposure)
keep rejecting file:// — the loose policy doesn't apply.

Also adds per-reason diagnostic logging in
_ws_host_origin_is_allowed, so future ws-guard rejections name the
specific clause that fired (bad_host / bad_origin_scheme /
origin_host_mismatch) instead of the opaque
"non_loopback_or_bad_origin" surfaced at the call site.

Verified against tests/hermes_cli/test_web_server_host_header.py
(all 11 upstream tests still pass) and hand-tested by opening the
bb/gui Electron desktop dev build against the patched backend.

* fix(tui_gateway): restore _content_display_text helper

Bb/gui had dropped the helper but the orchestrator code merged from main
still calls it (_inflight_text, _message_preview). Re-add the definition
verbatim from main so session.create / _start_inflight_turn don't crash
with NameError on first prompt submit.

* fix(tui-gateway): restore _content_display_text helper lost in main merge

The May 27 merge of origin/main into bb/gui re-introduced two callers of
_content_display_text (in _inflight_text and _history_to_messages) but
dropped the helper definition itself, leaving an unresolved reference.

NameError fires on every user message via _start_inflight_turn ->
_inflight_text, taking down both the TUI and the desktop (which share
this gateway backend) the moment input is dispatched.

Restores the helper verbatim from main (commit 36c99af37) -- pure
structured-content text extractor, no other dependencies.

* fix(telegram): import Set for _dm_topic_chat_ids annotation

self._dm_topic_chat_ids: Set[str] = {...} at line 460 references Set
but only Dict, List, Optional, Any are imported from typing. The file
has no 'from __future__ import annotations', so the annotation is
evaluated at runtime and raises NameError on TelegramAdapter
construction.

* fix(setup): drop shadowing inner importlib.util re-imports

_print_setup_summary and _setup_tts_provider each had 'import
importlib.util' inside a try: block nested deeper in the function
body. Python flips importlib to function-local for the whole scope,
so earlier references in the same function (the neutts branches at
lines 493 / 1109) hit UnboundLocalError before the late import can
run.

The top-of-module 'import importlib.util' at line 14 already covers
both call sites, so dropping the redundant inner imports restores
the intended behavior.

* feat(install.ps1): add -IncludeDesktop switch + Stage-Desktop

The new Hermes-Setup.exe (Tauri bootstrap installer) passes -IncludeDesktop
so users who install via the GUI end up with a launchable Hermes.exe at
apps/desktop/release/<os>-unpacked/. Existing flows are unchanged:

  * The 'irm install.ps1 | iex' CLI one-liner omits the flag — terminal
    users don't need a prebuilt desktop binary; 'hermes desktop' builds
    on demand.
  * The Electron desktop's bootstrap-runner.cjs also omits the flag —
    rebuilding apps/desktop from inside a running Hermes.exe would try
    to overwrite the live binary on disk and fail.

Stage-Desktop runs after Stage-NodeDeps so workspace npm is already
installed when electron-builder fires. It does:
  1. 'npm install' at repo root so apps/* workspaces resolve their deps
     (Electron itself arrives via npm here, ~150MB)
  2. 'npm run pack' in apps/desktop (tsc + vite + electron-builder --dir)
  3. Probes apps/desktop/release/{win-unpacked,win-arm64-unpacked}/Hermes.exe

The --dir mode produces an unpacked launchable binary without an NSIS/MSI
installer artifact — we don't need one because Hermes-Setup.exe spawns the
unpacked binary directly via launch_hermes_desktop.

* feat(installer): Tauri bootstrap installer for first-time onboarding

Hermes-Setup.exe is a small signed Rust+Tauri binary that drives
scripts/install.ps1 stage-by-stage with a native UI matching the
desktop's design language. Replaces the chicken-and-egg pattern of
shipping a 200MB Electron app whose first launch existed only to
run install.ps1.

The architecture:

  Rust backend (src-tauri/):
    bootstrap.rs        orchestrator -- Tauri commands, stage iteration
    install_script.rs   resolve install.ps1 (dev checkout, cache, GitHub raw)
    powershell.rs       spawn powershell, line-stream stdout/stderr, parse JSON
    events.rs           BootstrapEvent types -- mirror bootstrap-runner.cjs
    paths.rs            HERMES_HOME resolution + tracing log setup
    build.rs            bakes BUILD_PIN_COMMIT / BUILD_PIN_BRANCH from
                        'git rev-parse HEAD' at compile time

  React frontend (src/):
    Tauri webview rendering 4 screens (welcome / progress / success /
    failure), driven by nanostores subscribing to the Rust event stream.
    Visual layer reuses the desktop's styles.css wholesale via @import
    so the installer and desktop never drift visually.

  Distribution:
    targets = ['app', 'dmg', 'appimage'] -- no NSIS/MSI wrapper. The
    raw target/release/Hermes-Setup.exe IS the artifact on Windows;
    .dmg + .app on macOS; AppImage on Linux. One file, double-click,
    no installer-installing-an-installer pattern.

  Compile-time pinning:
    build.rs reads 'git rev-parse HEAD' and emits
    cargo:rustc-env=BUILD_PIN_COMMIT=<sha> + BUILD_PIN_BRANCH=<branch>.
    bootstrap.rs's option_env!() picks these up so the binary fetches
    install.ps1 from the exact SHA it was tested against. CI / release
    builds can override via HERMES_BUILD_PIN_COMMIT env var.

  Windows manifest:
    hermes-setup.manifest declares level='asInvoker' so the
    productName 'Hermes Setup' doesn't trip Windows's installer-
    detection heuristic and refuse to launch without elevation.
    Also declares PerMonitorV2 DPI + UTF-8 active code page + Common
    Controls v6.

Limitations of this initial version:

  * No code signing -- Windows SmartScreen will warn once on Hermes-Setup.exe
    ('More info -> Run anyway'). The downstream binaries it produces
    (Hermes.exe in win-unpacked/, the hermes CLI) are locally-built and
    therefore don't carry MOTW, so they launch without SmartScreen
    intervention. Cert procurement tracked separately.

  * macOS and Linux build paths defined but untested -- Windows-only V1.

* fix(installer): pass -IncludeDesktop to manifest, surface launch errors, alias hermes desktop

Three bugs found in the first VM end-to-end test:

1. install.ps1 -Manifest was called WITHOUT -IncludeDesktop, so the
   manifest came back with the 14-stage list (no desktop stage), the
   UI showed '14 steps' and Stage-Desktop never ran. Pass the flag to
   both the manifest fetch and the per-stage runs — install.ps1 gates
   the desktop stage's inclusion on the flag.

2. The Success screen's Launch button silently swallowed the Tauri
   error when no Hermes.exe existed (e.g. Stage-Desktop was skipped).
   Wire the error through to inline UI with an alert callout, so the
   user gets actionable text ('Hermes.exe missing, run hermes desktop
   from a terminal') instead of an unresponsive button.

3. The Success screen tells users to run 'hermes desktop' from a
   terminal but the CLI only accepted 'hermes gui' — invalid choice
   for 'desktop'. Rename the subcommand canonically to 'desktop' with
   'gui' as a backwards-compatible alias. Update the _SUBCOMMANDS sets
   used by session-flag arg parsing + logging-mode probe so both names
   route to the same logic.

* fix(install.ps1): pre-warm electron-builder winCodeSign cache + fix Stage-Desktop $HasNode false-skip

Two bugs caught in the second VM end-to-end run:

1. electron-builder's winCodeSign extraction fails on grandma-class
   Windows boxes because the .7z archive contains macOS symlinks
   (darwin/10.12/lib/libcrypto.dylib and libssl.dylib pointing at
   versioned siblings). Creating symlinks on Windows requires
   SeCreateSymbolicLinkPrivilege, a per-user right that non-admin
   accounts don't have on stock Windows. Result: every fresh install
   on a non-admin user fails Stage-Desktop with a 7-Zip 'cannot create
   symbolic link' error, retried four times, then bails.

   Fix: Initialize-ElectronBuilderCache pre-extracts winCodeSign-2.6.0.7z
   ourselves with -snl (don't preserve symlinks, store as resolved file
   content) AND -x!darwin (skip the entire macOS subtree — irrelevant
   on Windows). Writes to electron-builder's expected cache dir before
   electron-builder gets a chance to try its own broken extraction.
   Idempotent — fast-paths via signtool.exe sentinel check.

2. Install-Desktop's first guard was 'if (-not $HasNode) skip'.
   $HasNode is set by Stage-Node into $script:HasNode, but in
   cross-process driver mode (each -Stage NAME is a fresh powershell.exe
   spawned by Hermes-Setup.exe), that script-scope variable from the
   PREVIOUS process is invisible — so the guard always fired and
   Install-Desktop returned in 900ms with a misleading
   'Node.js not available' reason. The real npm probe below it never
   got to run. Fix: re-probe npm directly via Get-Command when $HasNode
   is empty/false, since by that point Stage-Node has already verified
   Node is installed and the only question is whether *this* process
   can see it on PATH (it can — installer-wide PATH update from Stage-Node).

* fix(install.ps1): tell electron-builder we're NOT signing instead of pre-extracting winCodeSign

The previous commit (c7e46f9f3) worked around the winCodeSign-symlinks-
on-Windows extraction crash by pre-extracting the archive ourselves with
-snl + -x!darwin. That fix was correct but addressed the wrong layer.

The deeper question: why was electron-builder fetching winCodeSign at all
when we have no signing cert configured? Answer: electron-builder
unconditionally pre-warms the toolchain assuming any build MIGHT sign.
The cert auto-discovery never finds anything (we never set CSC_LINK
or anything else), so the signing never happens — but the 100MB fetch
of winCodeSign and its broken-on-Windows symlink extraction does.

Set CSC_IDENTITY_AUTO_DISCOVERY=false (with WIN_CSC_LINK and
WIN_CSC_KEY_PASSWORD also explicitly cleared as belt-and-suspenders)
before invoking npm run pack, and electron-builder skips the entire
winCodeSign apparatus. No download, no extraction, no privilege check.
Env vars are saved/restored around the invocation so we don't leak
the override into Stage-PlatformSdks etc.

Net: removes the 100-line Initialize-ElectronBuilderCache helper that
manually downloaded + extracted winCodeSign-2.6.0.7z. Replaced with
3 env-var assignments. The produced Hermes.exe is functionally
identical — just no longer carries a code-signing-machinery dependency
we never used.

* fix(installer): bump bootstrap-installer.log to capture stage transitions + every install.ps1 line

Diagnosing the second VM failure was impossible because bootstrap-installer.log
contained only the 'starting' banner. Two causes:

1. emit_log() inside run_bootstrap() was tracing::debug! — dropped on the
   floor under the default INFO env-filter.

2. The per-stage sink callbacks (on_stdout_line / on_stderr_line) only
   emitted Tauri events to the frontend; they never tee'd to the log file
   at all. When the failure route mounts, the Tauri event stream is the
   only place the script output lived, and it gets discarded.

3. The Failed / Stage / Manifest / Complete lifecycle frames in emit_event()
   were also Tauri-only — so even the 'which stage failed' frame never
   reached the log.

Fixes:
  * emit_log() → tracing::info!
  * Sink callbacks tee stdout to info!, stderr to warn!, with stage label
    as a structured field for grep'ability
  * emit_event() now matches on the variant and logs each lifecycle frame
    at the right level: Failed → tracing::error!, others → info!

Result: a failing install leaves a complete forensic trail in
bootstrap-installer.log — manifest stage list, every install.ps1
stdout/stderr line tagged by stage, the stage transitions, and the
final error. Same path as before so nothing the user does changes.

* fix(install.ps1): Stage-NodeDeps cross-process $HasNode + stream npm install output to bootstrap log

VM run 3 diagnosis: node-deps stage skipped on the VM (logged
'Skipping Node.js dependencies (Node not installed)') and then
desktop's npm install failed with exit 1 and zero diagnostic detail.

Two root causes:

1. $HasNode false-skip in Stage-NodeDeps — same cross-process bug
   pattern we fixed for Stage-Desktop in c7e46f9f3. Stage-Node ran
   in process A and set $script:HasNode = $true, then exited. Stage-
   NodeDeps ran in fresh process B (Hermes-Setup.exe -Stage NAME
   spawns each stage independently), where that variable doesn't
   exist. Re-probe via Get-Command npm instead of trusting the
   stale script-scope global. The previous stage already verified
   Node so the re-probe succeeds.

2. npm install --silent + Tee to TEMP file hid the real error.
   When the workspace install failed on the VM, the actual reason
   was buffered in $env:TEMP\hermes-npm-desktop-install-*.log and
   the user saw only 'exit 1'. Drop --silent so npm streams its
   full output, drop the TEMP-file dance — the Tauri installer's
   streaming sink already tees every stdout/stderr line to the
   rolling bootstrap-installer.log, so a side log file is dead
   weight that hides the very error we need.

After this, the bootstrap log on a failure will contain npm's full
output (deprecation warnings, ETARGET, native-module compile errors,
whatever) tagged with stage=desktop, making the actual cause
diagnosable instead of an opaque exit code.

* fix(install.ps1): restore Initialize-ElectronBuilderCache (CSC env vars alone aren't enough)

VM run 4 diagnosis: even with CSC_IDENTITY_AUTO_DISCOVERY=false set,
electron-builder still fetches winCodeSign and signs bundled binaries.
The log shows the signing happens BEFORE the cache extraction:

  • signing with signtool.exe  ...\winpty-agent.exe
  • signing with signtool.exe  ...\OpenConsole.exe
  • downloading winCodeSign-2.6.0.7z
  • <symlink privilege error>

Cause: node-pty's bundled prebuilds are listed in apps/desktop's
asarUnpack ['**/*.node', '**/prebuilds/**']. electron-builder
re-signs anything unpacked from asar, regardless of whether OUR
binary gets signed. The signtool invocation needs winCodeSign on
disk, which needs the .7z extracted, which hits the macOS-symlink
crash on non-admin Windows.

The CSC env vars I added in d5fe46727 only kill IDENTITY DISCOVERY
(so OUR Hermes.exe stays unsigned, which is fine — we have no cert).
They don't prevent the toolchain fetch for the bundled-prebuild
re-sign. I removed the pre-extract in d5fe46727 thinking the env
vars subsumed it; that was wrong. Both are needed.

Restoring Initialize-ElectronBuilderCache verbatim from c7e46f9f3
and keeping the CSC env vars. Wrote a clearer doc-comment at the
call site explaining the two-knob interaction so future maintainers
don't drop one half again.

* fix(desktop): disable signtool via signtoolOptions.sign=null, drop dead winCodeSign pre-extract

VM run 5 diagnosis: the pre-extract from 3b29e65c1 ran (extracted 83
files, 24MB) but produced ZERO files at the expected sentinel path
'/winCodeSign-2.6.0/windows-10/x64/signtool.exe'.

Cause: the .7z archive's root entries are 'windows-10/', 'darwin/',
'linux/', etc. — not 'winCodeSign-2.6.0/<arch>'. Extracting with
'-o$cacheRoot' put files at $cacheRoot/windows-10/..., NOT at
$cacheRoot/winCodeSign-2.6.0/windows-10/.... I had the directory
nesting wrong from the start.

And then we observed: electron-builder downloads winCodeSign-2.6.0.7z
under a random numeric filename ('384387955.7z') regardless of what's
already extracted in the parent dir. The cache key isn't the dirname;
it's content-addressed. So the pre-extract approach was doomed even
if the path nesting had been right.

Actual fix: signtoolOptions.sign=null in apps/desktop/package.json's
win build config. electron-builder honors this and skips the bundled-
prebuild signing entirely — no signtool invocation, no winCodeSign
fetch, no symlink-privilege crash. The previous failures all stemmed
from electron-builder pre-signing node-pty's bundled .exes
(winpty-agent.exe, OpenConsole.exe) which are already author-signed
upstream; re-signing with our nonexistent cert was overwriting good
sigs with nothing useful anyway.

Cost: when we DO get a real cert later, we'll add it back with the
sign function pointing at the cert chain. Until then, all-null is
the correct config and unblocks every non-admin Windows user.

Removed Initialize-ElectronBuilderCache (the dead pre-extract).
Removed the call site. Kept the CSC_IDENTITY_AUTO_DISCOVERY env
vars as belt-and-suspenders against a future electron-builder
change that might revive cert auto-discovery.

* fix(desktop): use no-op sign function instead of sign=null

VM run 6 still hit the symlink crash even with signtoolOptions.sign=null.
electron-builder 26.8.1 treats null as 'use the default signtool path'
rather than 'skip signing', so the winCodeSign fetch + extraction still
fired for the bundled prebuild re-sign.

The Electron docs (electronjs.org/docs/latest/tutorial/code-signing)
make it clear signing is OPTIONAL and unsigned apps work fine — users
just see SmartScreen on first launch. The electron-builder mechanism
for 'don't actually sign anything' is to supply a custom sign function
(via signtoolOptions.sign: '<path-to-cjs-module>') that resolves
without invoking signtool.

build-noop-sign.cjs is that module — a 5-line async function that
returns undefined. electron-builder calls it for every binary it would
have signed, gets back a resolved promise, and considers each binary
'signed.' No signtool spawn, no winCodeSign fetch, no symlink crash.

When Nous's cert arrives, replace this file with a real signing hook
(@electron/windows-sign-based or a direct signtool invocation). The
architecture's signing-ready and the cutover is a one-file edit.

* fix(desktop): signAndEditExecutable=false to skip signtool path entirely

After reading app-builder-lib/winPackager.js line 216 + 231 directly:
signAndEditExecutable is the ACTUAL hardcoded gate that short-circuits
both signApp() (which signs Hermes.exe + every shouldSignFile match
including bundled prebuilds) AND createTransformerForExtraFiles().
None of signtoolOptions.sign / sign:null / sign:<custom-fn> gate the
winCodeSign download — that happens before they're consulted.

What we lose: rcedit also runs through signAndEditResources, so
disabling this drops PE metadata (file properties showing 'Hermes' /
'Nous Research' / file description). Cost is real but bounded:
  * Hermes.exe filename, icon, asar contents, app identity intact
  * Task Manager shows 'Hermes.exe' (the filename) not 'Hermes' (PE
    description) — minor downgrade
  * Start menu, taskbar, window title all work normally
  * SmartScreen will warn once (unsigned, same as before)

When the cert lands, flip signAndEditExecutable back to default true,
both signing AND rcedit return, PE metadata is restored.

Removes the no-op sign function (build-noop-sign.cjs) since
signAndEditExecutable=false prevents signtool from being invoked at
all — the custom hook never gets called either.

* feat(install.ps1): write .hermes-bootstrap-complete marker at end of install

The desktop app's main.cjs resolver ladder has a 'bootstrap-needed' rung
that fires when .hermes-bootstrap-complete is missing from
ACTIVE_HERMES_ROOT. Pre-Hermes-Setup, this marker was written by the
packaged-desktop's own bootstrap-runner.cjs at the end of its install
flow. Now that Hermes-Setup.exe runs install.ps1 directly, install.ps1
needs to own the marker — otherwise the desktop sees no marker on first
launch and triggers its legacy first-launch bootstrap (re-running
install.ps1 from inside Electron, the exact recursion Hermes-Setup.exe
was supposed to obviate).

Implementation:
  * New Stage-BootstrapMarker (worker) → Write-BootstrapMarker (helper)
  * Slotted in the manifest right after platform-sdks, before the
    interactive configure/gateway stages, so it runs unconditionally
    when the install reaches the finalize phase
  * Schema mirrors apps/desktop/electron/main.cjs writeBootstrapMarker /
    isBootstrapComplete EXACTLY: {schemaVersion: 1, pinnedCommit,
    pinnedBranch, completedAt}. Schema version stays at 1 so old
    desktops that read marker files written by future install.ps1s
    can still parse them.
  * pinnedCommit comes from -Commit flag (Hermes-Setup.exe passes it)
    or falls back to 'git rev-parse HEAD' in InstallDir
  * pinnedBranch from -Branch flag, defaults to 'main' matching
    install.ps1's own param default

Two PS-5.1 gotchas baked into comments:
  * The ?. null-conditional operator doesn't exist pre-PS7; use
    explicit if-checks on Get-Command results
  * Set-Content -Encoding UTF8 emits a BOM in 5.1 and Node's plain
    JSON.parse rejects BOM — write via .NET's UTF8Encoding(false)
    to produce BOM-less JSON the desktop's readJson() can parse

* feat(installer): drive in-app updates through the Tauri installer

Converge update on the same principle as bootstrap: one driver owns all
repo mutation. The desktop becomes a pure consumer that hands off to
Hermes-Setup.exe --update instead of re-implementing git/pip in Electron.

- hermes desktop --build-only: build without launching, so the installer
  owns the post-update launch (CLI keeps build logic single-sourced).
- Installer AppMode {Install,Update} from argv; get_mode exposed to the UI.
- Installer self-copies to HERMES_HOME/hermes-setup.exe on install success
  (no-op guard during --update re-invocation to avoid the locked-exe copy).
- Installer --update flow (update.rs): wait for the desktop to release the
  venv shim, run 'hermes update --yes --gateway' (branch on exit 0/2/other),
  then 'hermes desktop --build-only', then launch the rebuilt desktop. Reuses
  the bootstrap event channel + progress UI via a synthetic two-stage manifest.
- Desktop applyUpdates() gutted (~105 lines of git/stash/pull/pyproject/pip
  removed) -> thin handoff: spawn updater, app.quit() to free the shim.
  Detection (checkUpdates, commit changelog, behind-count) kept intact.
- install.ps1 creates Start Menu + Desktop shortcuts to the packed Hermes.exe
  (never bare 'hermes desktop', which would rebuild every launch).

* test update

* fix(installer): pass --branch to hermes update in the --update flow

The install is a detached-HEAD checkout of a pinned commit. Without
--branch, 'hermes update' fell back to its default (main) and switched
the checkout to main — a divergent branch that lacks the desktop CLI
command — so the update targeted the wrong branch and the rebuild stage
failed with 'invalid choice: desktop'.

Thread BUILD_PIN_BRANCH (the branch this installer was built against,
and the same branch the desktop detected the update on) into
'hermes update --branch <b>' so update + rebuild stay on-branch.

* test update

* fix(installer): stamp Hermes icon onto Hermes.exe via rcedit (no winCodeSign)

The unpacked Hermes.exe showed the stock Electron icon + name in the
taskbar because build.win.signAndEditExecutable=false disables BOTH
electron-builder's signing AND its rcedit metadata/icon stamping. That
flag is load-bearing: enabling it re-triggers signtool -> winCodeSign,
whose macOS symlinks crash 7-Zip on non-admin Windows (unfixable dead end).

Decouple identity-stamping from signing entirely: after npm run pack,
run rcedit ourselves on the produced exe.
- Add rcedit as a direct devDependency of apps/desktop (the transitive
  electron-winstaller copy is fragile).
- apps/desktop/scripts/set-exe-identity.cjs: Node helper that calls
  rcedit's named export to set icon + ProductName/FileDescription/
  CompanyName. Node builds argv natively — avoids the PowerShell->exe
  ->JSON double-escaping that broke the app-builder rcedit path.
- install.ps1 Set-DesktopExeIdentity invokes the script after the build,
  before shortcuts. Best-effort: failure keeps the stock icon, never
  fails the install. rcedit is a pure PE editor — no signtool, no
  winCodeSign, no symlinks.

Verified locally: stamping a copy of the built Hermes.exe embeds the
32x32 icon and sets ProductName=Hermes.

Also fix update-path success-screen flash: in update mode the installer
hands off + exits in ~600ms, so don't route to the 'launch Hermes'
success view (it flashed before the window closed).

* update test

* fix(desktop): show 'hermes update' guidance for CLI installs instead of dead-end error

A user who installed via the CLI (irm|iex / install.sh) then ran
`hermes desktop` has no staged hermes-setup.exe, so clicking Update
in-app hit resolveUpdaterBinary()=null and showed a misleading error
('re-run the Hermes installer') with a Try-again button that could
never succeed — a dead loop for a perfectly valid install.

Treat the no-updater case as an intentional outcome, not a failure:
- main.cjs applyUpdates returns { ok:true, manual:true, command:'hermes update' }
  (no throw, no 'error' stage) when no updater binary exists.
- New 'manual' update stage + apply-state.command thread the command to the UI.
- updates-overlay ManualView: a polished terminal-native card with the
  exact command and a copy button, framed as the correct path for a CLI
  user rather than an error.

GUI-installer users are unaffected — hermes-setup.exe present => seamless
auto-update runs as before. Zero new process orchestration; can't fail
the update demo.

* update test

* fix(gui): pin /api/hermes/update to the current branch

The desktop command-center 'update' action hits POST /api/hermes/update,
which spawned bare `hermes update` with no --branch. cmd_update then
falls back to its default (main) and checks the working tree OUT of the
tracked branch — a bb/gui install silently jumped to main and lost the
desktop CLI.

Resolve the checkout's current branch and pass --branch <current> from
this endpoint only. The engine default (main) is DELIBERATELY unchanged:
bare `hermes update` from a terminal, the gateway /update bot command,
and the CLI/TUI relaunch path all keep their long-standing 'update against
main' contract for the existing user base. Only the GUI button is scoped
to update-the-branch-you're-on. Detached HEAD / git failure falls back to
the bare default.

* update test

* fix(desktop): branch-pin the CLI manual-update command card

The 'Update from your terminal' card (shown to CLI installs with no staged
updater) hardcoded bare `hermes update` — which defaults to main and would
switch a bb/gui (or any non-main) checkout off-branch. Same bug we fixed for
the GUI button, leaked into the card's copy text.

Resolve the checkout's current branch and show `hermes update --branch
<current>` for non-main checkouts; keep it bare for main so the card stays
clean. Best-effort: bare fallback if branch detection fails. Matches the
GUI button + installer --update contract; bare terminal/bot/TUI update
paths still default to main, unchanged.

* docs: phragg was here

* feat(desktop): lead onboarding with Nous Portal + fix fresh-install detection (#34970)

- Feature Nous Portal as the primary onboarding card (Recommended tag,
  app logo, single pitch line); collapse other OAuth providers behind an
  "Other providers" disclosure whose open/closed state persists.
- Surface OpenRouter as a one-click API-key option inside the disclosure;
  move "I have an API key" to a quiet bottom-right link.
- Treat "no provider configured" as a normal onboarding state, not a red
  error banner (provider-setup-errors copy match).
- Fix setup.runtime_check: it reported ready when the resolved runtime had
  an empty credential or only implicit Bedrock/IAM, so fresh installs never
  saw onboarding. Now requires a usable credential.
- Auto-wire Windows fonts for WSL2 users so the renderer renders real
  Segoe UI instead of the DejaVu fallback; make WSL detection env-independent
  via the /proc kernel marker.

* feat(desktop): live elapsed timer on install bootstrap steps

The first-launch install overlay showed a static "Installing" with no
motion, so long steps (notably the repo clone) looked frozen. Stamp each
stage's start time on the running transition and tick once a second so the
active step shows live elapsed (e.g. "Installing · 1:23"), plus elapsed on
the overall current-step line. Completed steps keep their final duration.

* fix(desktop): resolve PortableGit for update checks + reserve titlebar tools space

- runGit() hardcoded spawn('git'), which ENOENTs on fresh installer-driven
  Windows installs (git is PortableGit under %LOCALAPPDATA%\hermes\git, never
  on PATH) — so "Check for updates" failed with "Couldn't check for updates".
  Add resolveGitBinary() mirroring findGitBash (PortableGit → Git-for-Windows
  → PATH) and use it in runGit.
- PageSearchShell rendered a full-width search input in the titlebar row, so
  on Windows its right edge slid under the fixed top-right tools + native
  window controls. Reserve that footprint via --titlebar-tools-* vars.

* fix(desktop): stop streaming caret from shifting layout on completion

The streaming caret (::after on the running message's last child) was an
in-flow inline-block adding ~0.78em of inline width, which could wrap the
last line mid-stream; when the caret is removed on completion the line
un-wraps and reflows — the visible post-response layout shift. Net-zero its
inline advance with a compensating negative margin so it paints at the text
end without consuming layout width.

* fix(desktop): stop completed-message layout shift while streaming

The assistant message action bar used `hideWhenRunning`, which unmounts it
whenever the thread is streaming. Since the bar reserves vertical space in
each completed assistant message's footer (it's invisible-until-hover via
opacity, not via mount), unmounting it collapsed every prior turn by the
bar's height — then remounting on resolve grew them back, shifting the whole
conversation (visible as "padding appears above the last user message").
Drop hideWhenRunning so the footer height is constant; the bar stays
invisible during streaming via its existing opacity/pointer-events gating.

* fix(merge): keep windows-footgun suppressions inline

* fix(merge): keep remaining gateway footgun suppressions inline

* fix(merge): restore contracts caught by main-target CI

* fix(dashboard): honor injected HERMES_DASHBOARD_SESSION_TOKEN

The desktop shell mints a session token and signs its /api + /api/ws
calls with it via HERMES_DASHBOARD_SESSION_TOKEN, but the main-merge
restored a web_server.py that ignored the env var and minted its own
random _SESSION_TOKEN -- so every desktop request 401'd and the UI
reported "gateway offline". Read the injected token (fall back to a
fresh random one) so loopback HTTP + WS auth line up.

Adds a regression test so a future merge can't silently drop the read.

* fix(desktop): align fresh-install home so upgraders don't brick

Two related first-launch bugs on machines with a legacy ~/.hermes:

- install.ps1 hardcoded $HermesHome/$InstallDir to %LOCALAPPDATA%\hermes
  and ignored the HERMES_HOME the desktop passes through. The desktop
  freezes HERMES_HOME at module load and prefers a legacy ~/.hermes when
  %LOCALAPPDATA%\hermes is absent, so the installer wrote to a different
  home than the shell read -> "Could not connect to Hermes gateway". Honor
  $env:HERMES_HOME in the param defaults.

- isBootstrapComplete() trusted the marker + checkout without verifying a
  runnable venv, so an interrupted/split install spawned a dead backend
  instead of re-bootstrapping. Also require the venv python to exist.

* fix(dashboard): allow packaged desktop file:// origin on loopback WS

The packaged Electron desktop loads its renderer over file://, so its
/api/ws handshake carries Origin: file:// (or null). The DNS-rebinding
WebSocket Origin guard only accepted http(s) origins matching the bound
host, so it rejected the desktop's own renderer with 4403 -> "Could not
connect to Hermes gateway" on macOS.

A browser DNS-rebinding attacker can only ever present an http(s) origin
(the site hosting the malicious page); it cannot forge file://, null, or
a custom app scheme AND hold the loopback session token. So on loopback
binds we now trust non-web origins -- the token in _ws_auth_ok remains
the real authenticator. Public/gated binds still reject them, and
cross-site http(s) origins are still rejected everywhere.

* fix(desktop): resolve renderer assets relative to BASE_URL

Absolute public asset paths (/apple-touch-icon.png, /ds-assets/...) work
under the dev server but break in the packaged app, where the renderer is
loaded from file://.../index.html and a leading slash resolves to the
filesystem root -> broken onboarding provider icon and backdrop image on
macOS. Prefix these with import.meta.env.BASE_URL so they resolve next to
the bundled index.html in both dev and packaged builds.

* feat(desktop): automate first-launch bootstrap on macOS/Linux

Previously a packaged macOS/Linux app with no Hermes install hit a
dead-end ("first-launch install is not yet automated -- run install.sh
manually") because install.sh lacked the staged protocol install.ps1
exposes. Now both platforms bootstrap on first launch with the same
structured, per-step progress UI as Windows.

- install.sh: add --manifest / --stage / --json / --non-interactive plus
  a stage dispatcher (prerequisites, repository, venv, python-deps,
  node-deps, path, config, setup, gateway, complete). User-input stages
  (setup, gateway) are skipped under --non-interactive; the in-app
  onboarding overlay owns API keys/model, matching the Windows flow.
  Each stage runs inside the install dir (its own process) and a new
  --commit flag pins the checkout to the build-stamp SHA.
- bootstrap-runner.cjs: drive the staged manifest/stage/JSON protocol for
  both install.ps1 (PowerShell) and install.sh (bash), selected by
  installer kind; removed the single-blob POSIX shim.
- main.cjs: drop the macOS/Linux unsupported-platform dead-end so the
  bootstrap-needed path runs the installer on every platform.

* fix(dashboard): return 404 JSON for unmatched /api paths instead of SPA HTML

The SPA catch-all (serve_spa) served index.html for any unmatched GET,
including unregistered /api/* endpoints. A missing API route therefore
came back as <!doctype html> with status 200, and JSON clients (the
desktop app's fetchJson) crashed with an opaque
'SyntaxError: Unexpected token <' instead of a clear error.

- web_server.py: unmatched /api or /api/... now returns 404 JSON
  ('No such API endpoint'); non-api paths still serve the SPA for
  client-side routing.
- main.cjs fetchJson: detect an HTML body / text/html content-type on a
  2xx response and reject with a clear message naming the URL, rather
  than a raw JSON.parse SyntaxError. Empty bodies resolve to null;
  malformed JSON reports the URL plus a snippet.

* say 'OS appearance' instead of 'macOS appearance'

* feat(install): add --include-desktop stage + PowerShell-style flags to install.sh

Brings install.sh to parity with install.ps1's bootstrap surface so the
shared Rust/Tauri bootstrapper (apps/bootstrap-installer) can drive a
macOS/Linux install the same way it drives Windows.

- Accept the PowerShell-style aliases the bootstrapper emits to both
  installers: -Commit / -Branch (alongside existing -Manifest / -Stage /
  -Json / -NonInteractive).
- Add --include-desktop / -IncludeDesktop. When set, the manifest gains a
  'desktop' stage (immediately before 'complete'), and a new install_desktop
  runs a root workspace `npm install` + `npm run pack` (electron-builder
  --dir, signing auto-discovery disabled) to produce release/mac*/Hermes.app
  -- mirroring install.ps1's Install-Desktop / Stage-Desktop.
- The flag is opt-in, exactly like Windows: the signed bootstrap installer
  passes it; the Electron app's own first-launch bootstrap and the CLI
  one-liner omit it (building the desktop from inside the running app would
  clobber it).

* fix: tts endpoints

* macOS desktop: install + in-app self-update (#35607)

* fix(installer): align macOS HERMES_HOME with the rest of the stack

paths.rs computed the macOS Hermes home as ~/Library/Application Support/
hermes, but nothing else does: hermes_constants.get_hermes_home() (Python),
scripts/install.sh, and the Electron desktop's resolveHermesHome() all use
~/.hermes on macOS. The drift meant the Tauri installer wrote the install to
one directory and the desktop looked for it in another, so a fresh GUI
install never found its backend (the file's own comment warned this exact
drift would break things). Use ~/.hermes on macOS to match.

* fix(install.sh): always emit a stage result frame on failure

Stage helpers (clone_repo, install_deps, check_python, …) were written for
the monolithic flow and call `exit 1` on failure. Under `--stage`, that
terminated the process before the JSON result frame was printed, so the
installer's parse_stage_result saw "no frame" instead of a clean
{ok:false,...} contract response. Run the stage body in a subshell so an
`exit` only unwinds the subshell and the parent still emits the frame.

* feat(install.sh): auto-provision git on macOS/Linux (parity with install.ps1)

install.ps1 downloads PortableGit on Windows, but install.sh just printed a
"please install git" hint and exited — so a fresh Mac with no developer tools
(no Xcode CLT → no git) couldn't get past the clone step. check_git now tries
to install git before bailing:
  - macOS: Homebrew if present (headless), else `xcode-select --install`
    (the CLT prompt also provides the compiler some wheels need), polling for
    git to appear.
  - Linux: apt/dnf/pacman via sudo when available.
Falls back to the manual instructions only if auto-provision fails.

* feat(desktop): in-app GUI+backend self-update on macOS/Linux

On Windows the staged Hermes-Setup binary drives updates (quit → hermes
update → hermes desktop --build-only → relaunch). The mac drag-install has no
such binary, so "Update now" previously just printed `hermes update`.

Since there's no venv-shim file lock on POSIX, the desktop can drive the whole
update itself. applyUpdates now, when no staged updater exists on mac/linux:
  1. runs `hermes update --yes [--branch <current>]` (backend git pull + deps),
  2. runs `hermes desktop --build-only` (OS-aware GUI rebuild) with the
     Hermes-managed Node + venv on PATH,
  3. spawns a detached swapper that waits for this process to exit, dittos the
     freshly built Hermes.app over the running bundle, clears quarantine, and
     relaunches.
Degrades to "backend updated — restart to load the new GUI" if the rebuild
fails or there's no .app bundle to swap (dev run, Linux AppImage).

* fix(desktop): repair voice dictation on Windows

Voice dictation was broken on Windows in two ways:

1. Mic access was denied. The Electron permission request handler only
   granted 'media' requests whose details.mediaTypes included 'audio',
   but Chromium on Windows frequently fires the mic request with an empty
   mediaTypes array, so getUserMedia threw NotAllowedError. The handler
   now grants audio-capture when mediaTypes includes 'audio' OR is
   empty/absent, handles the 'audioCapture' permission name, and adds a
   setPermissionCheckHandler (the synchronous path Chromium also consults
   for getUserMedia on Windows). Video is still denied.

2. Transcripts went nowhere. The composer's insertText handler (used by
   dictation and other inserts) only updated the assistant-ui composer
   store via setText, never the contentEditable editor DOM. The
   draft->editor sync effect only re-renders the editor when it is NOT
   focused, and dictation runs while the editor has/regains focus, so the
   transcript was stored but never shown and could not be sent. insertText
   now renders into the editor DOM and places the caret, mirroring
   appendExternalText.

Also hardens fetchJson: a 2xx response with an HTML body (or text/html
content-type) now rejects with a clear message naming the URL instead of
an opaque JSON.parse 'Unexpected token <' error.

* feat(desktop): route Nous subscribers onto the Tool Gateway from the GUI

When the GUI sets the main provider to Nous via POST /api/model/set, call
the same apply_nous_managed_defaults the CLI uses after model selection, so
GUI/onboarding users land on the Nous Tool Gateway the same way CLI users do
— no separate prompt, no duplicated logic.

Purely additive: apply_nous_managed_defaults skips any tool where the user
has a direct key (FIRECRAWL_API_KEY, FAL_KEY, etc.) or explicit config, so it
never overwrites a user's own setup. Only unconfigured tools get routed.

- web_server.py: in set_model_assignment (scope=main, provider=nous), resolve
  enabled toolsets and apply managed defaults; guarded so a Portal hiccup never
  blocks saving the model. Returns routed tools as gateway_tools.
- onboarding.ts: surface a 'Tool Gateway enabled' toast listing routed tools.
- types/hermes.ts: add gateway_tools to ModelAssignmentResponse.
- tests: cover nous-applies, non-nous-skips, and failure-doesnt-block-save.

* feat(desktop): mirror hermes model free/paid curation in GUI onboarding

GUI onboarding picked models[0] from /api/model/options, which ignores the
Nous free/paid tier — a free user could land on a paid default (e.g.
anthropic/claude-opus-4). Now the recommended default mirrors what `hermes
model` does.

- web_server.py: new GET /api/model/recommended-default?provider=<slug>. For
  Nous it runs the same curation as the CLI (get_curated_nous_model_ids +
  pricing + check_nous_free_tier + union_with_portal_{free,paid}_recommendations
  + partition_nous_models_by_tier) so free users get a free model and paid users
  get the curated default. Other providers fall back to the first curated model.
  Never 500s — returns empty model on error so onboarding degrades gracefully.
- hermes.ts: getRecommendedDefaultModel client + RecommendedDefaultModel type.
- onboarding.ts: fetchProviderDefaultModel prefers the recommended endpoint,
  falls back to models[0] when unavailable.
- tests: free-tier picks free model, paid-tier picks curated default, failure
  returns empty without 500.

* feat(desktop): show model pricing + free/paid tier gating in GUI picker

The CLI `hermes model` picker shows per-model $/Mtok pricing and gates paid
models on free Nous accounts. The GUI picker showed bare model names. Bring it
to parity across both the model-picker dialog and onboarding confirm card.

Backend:
- inventory.build_models_payload gains a pricing=True flag → _apply_pricing
  enriches each provider row with formatted per-model pricing
  ({input,output,cache,free}) via the same _format_price_per_mtok the CLI uses,
  and for Nous adds free_tier + unavailable_models (paid models a free user
  can't select) via check_nous_free_tier + partition_nous_models_by_tier.
  Best-effort: any pricing/tier failure is swallowed and fails open (no gating).
- /api/model/options and TUI model.options now pass pricing=True so the
  global picker and in-session picker both carry pricing.

Frontend:
- ModelOptionProvider gains pricing/free_tier/unavailable_models; new
  ModelPricing type.
- model-picker dialog renders In/Out $/Mtok (or a Free pill) per model, a
  Free tier/Pro badge on the Nous heading, and disables + grays unavailable
  paid models for free users with a 'Pro models need a paid subscription' note.
- onboarding confirm card shows the chosen model's price + tier badge.

Tests: test_inventory_pricing covers price formatting, free-tier gating,
paid no-gating, providers without pricing, and swallowed failures.

* fix(desktop): GUI model picker shows curated Nous list in curated order

Two bugs made the GUI Nous model list diverge from the `hermes model` CLI picker:

1. Backend (model_switch.py): the Nous row in list_authenticated_providers
   fell through to cached_provider_model_ids("nous"), dumping the full live
   /v1/models catalog (~50 vendor-prefixed models, alphabetical). Now it uses
   the curated list AND applies the Portal free/paid recommendation union —
   exactly like _model_flow_nous in main.py — so newly-launched models such as
   stepfun/step-3.7-flash:free surface in curated order. Best-effort: falls
   back to the curated list alone if the Portal fetch fails.

2. Frontend (model-picker.tsx): cmdk's Command had shouldFilter on (default),
   which re-sorts items by fuzzy-match score (≈alphabetical) and ignores array
   order. Set shouldFilter={false} + own the search term and do an
   order-preserving substring filter, so the backend's curated order is shown
   verbatim.

* feat(desktop): add/switch providers from the model picker via onboarding reuse

The model picker could only select models from already-authenticated
providers. Switching to a new provider had no in-app path. Rather than
duplicate provider UI, reuse the existing onboarding provider selector
(featured Nous + other providers + API-key form + device-code/PKCE flow +
model-confirm with pricing/tier).

- onboarding store: add a 'manual' flag with startManualOnboarding() /
  closeManualOnboarding(). Manual mode forces the onboarding overlay to show
  even when configured===true and refreshOnboarding no longer auto-dismisses
  on runtime-ready (the app is already working — the user is just adding or
  switching a provider).
- onboarding overlay: render when manual even if configured; show a Close
  button (the first-run flow has none since the app can't run yet).
- model picker: 'Add provider' footer button opens the onboarding selector;
  ModelResults lists only configured (model-bearing) providers.

* feat(desktop): add PUT /api/tools/toolsets/{name} enable/disable endpoint

* feat(desktop): add toggleToolset RPC binding

* feat(desktop): toolset enable/disable switch in Tools settings

* feat(desktop): tool configuration parity in GUI Tools settings

Bring the desktop GUI Tools settings to parity with the CLI `hermes tools`
for provider selection and API-key configuration.

Backend (hermes_cli/web_server.py):
- GET  /api/tools/toolsets/{name}/config  - provider matrix + key status
- PUT  /api/tools/toolsets/{name}/provider - persist provider selection

Shared core (hermes_cli/tools_config.py):
- Extract apply_provider_selection / _write_provider_config from the
  interactive _configure_provider so the CLI and GUI write identical
  config keys (web.backend, tts.provider, browser.cloud_provider, plugin
  image/video providers, use_gateway flags) through one code path.

Desktop UI:
- ToolsetConfigPanel: provider list with select, per-provider API-key
  entry (set/replace/clear/reveal via the shared env RPCs), Ready/Needs
  keys state, guidance for Nous-auth and post-setup providers.
- Wire the Configured/Needs keys pill to expand the panel inline; refresh
  the toolset list after key changes so the pill updates live.
- Add getToolsetConfig / selectToolsetProvider RPC bindings + types.

Post-setup (OAuth/install) flows still defer to the CLI; see
docs spike findings for the planned /api/tools/setup/* endpoint family.

Tests: backend round-trip + 400 cases for the new endpoints and
apply_provider_selection; desktop vitest coverage for the config panel
(provider render, select, key save). No change-detector tests.

Also removes three stale completed plan docs.

* fix(desktop): show real Hermes version + sync package.json on release

The desktop app version was disconnected from the Hermes version: the
release script bumped pyproject.toml + hermes_cli/__init__.py but never
touched apps/desktop/package.json, which sat stale at 0.0.2 (lockfile at
0.0.1).

- main.cjs: hermes:version IPC now resolves __version__ from
  hermes_cli/__init__.py (the canonical source release.py bumps) via a new
  resolveHermesVersion() helper, falling back to app.getVersion() when the
  source tree isn't readable. The About panel now always shows the live
  Hermes version and can't drift.
- release.py: update_version_files() also bumps apps/desktop/package.json
  in lockstep with pyproject (top-level version only; dep specs untouched).
- One-time catch-up: package.json 0.0.2 -> 0.15.1 and the lockfile root
  mirrors 0.0.1 -> 0.15.1.

* fix(desktop): stamp exe identity in afterPack hook so updates stay branded

The packed Hermes.exe reverted to the stock Electron icon + "Electron" name
after an in-app update. The icon/identity stamp (rcedit) lived only in
install.ps1, but the installer's --update path rebuilds the desktop via
`hermes desktop --build-only` -> `npm run pack`, which never ran install.ps1
and so never stamped the rebuilt exe.

Move the stamp into an electron-builder afterPack hook so it runs for EVERY
packed build regardless of caller (first install, hermes desktop, the update
rebuild, or a manual npm run pack):

- set-exe-identity.cjs: refactor to export stampExeIdentity(exe, desktopRoot);
  still runnable as a standalone CLI.
- after-pack.cjs (new): afterPack hook calling stampExeIdentity. Windows-only
  guard; best-effort (logs + resolves on failure, never fails the build).
- package.json: register build.afterPack.
- install.ps1: remove the now-redundant Set-DesktopExeIdentity function + call;
  the hook handles it during npm run pack.

electron-builder's own rcedit step stays disabled (signAndEditExecutable=false)
to avoid the signtool -> winCodeSign -> 7-Zip macOS-symlink crash on non-admin
Windows; the hook runs rcedit directly (pure PE resource edit, no signing).

* fix(desktop): export afterPack hook as exports.default so electron-builder runs it

The afterPack hook used `module.exports = fn`, which electron-builder's hook
loader doesn't pick up — it expects the function as the module's default
export (the same shape afterSign/notarize.cjs uses). The hook silently never
ran, so even first install shipped the stock "Electron" exe.

Switch to `exports.default = async function afterPack(...)`. Verified with a
real `npm run pack`: electron-builder now invokes the hook and the produced
release/win-unpacked/Hermes.exe carries ProductName/FileDescription=Hermes.

* chore(desktop): drop auto-build release CI in favor of manual build + upload

Remove desktop-release.yml (nightly-on-main + stable publish). Installers
are now built locally per platform and uploaded to a GitHub Release by hand;
the website points at them via NEXT_PUBLIC_HERMES_DL_* env. Update README +
docs and drop the dead desktop-nightly channel links.

* fix(desktop): stable shortcut icon + bust icon cache so updates repaint

Symptom on a freshly-installed laptop: Hermes.exe itself shows the correct
Hermes icon (Explorer reads the live exe's stamped PE resource), but the
desktop shortcut still draws the stock Electron icon.

Cause: New-DesktopShortcuts set IconLocation to "<exe>,0", so Windows cached
the icon it extracted from the exe at shortcut-creation time. On an update the
exe gets re-stamped, but the shortcut keeps rendering the stale cached bitmap.

- package.json: ship assets/icon.ico beside the exe via extraResources
  (-> resources/icon.ico). Verified with a real npm run pack.
- install.ps1 New-DesktopShortcuts: point IconLocation at resources/icon.ico
  (fallback to <exe>,0 if absent) — a dedicated .ico is cache-stable and skips
  the per-exe extraction that goes stale. Then run `ie4uinit.exe -show` to bust
  the shell icon cache so the shortcut repaints immediately instead of showing
  the old Electron icon until reboot.

Both best-effort; never fail an otherwise-good install.

* dummy update

* feat(desktop): self-heal update branch + backend contract guard

Two fixes for the bb/gui→main transition:

- Self-update self-heals: if the tracked branch (e.g. bb/gui) no longer
  exists on origin (merged + deleted), the desktop updater falls back to
  main and persists it. Read-only ls-remote probe that only flips on a
  definitive "ref absent" (exit 2), never on a transient network error, so
  already-installed clients migrate themselves with no manual flip.
- Backend contract guard: tui_gateway reports DESKTOP_BACKEND_CONTRACT in
  session runtime info; the desktop warns with a one-click "Update Hermes"
  when the backend predates the GUI's required contract (e.g. a bb/gui app
  pointed at a main checkout) instead of failing cryptically downstream.

* docs(desktop): rewrite README to match current install/update/build flow

The old README contradicted itself (claimed a bundled Python payload while
also saying it no longer bundles source) and predated cross-platform support.
Rewrite for accuracy: Linux is a first-class build target, install.sh/install.ps1
both drive the staged bootstrap, the real self-update handoff (Windows
Hermes-Setup vs in-app macOS/Linux), and the bb/gui→main self-heal + backend
contract guard.

* docs(desktop): rewrite README as a real product readme

Lead with what the app is and how to get it (download an installer, or
`hermes desktop` for existing CLI users) plus a plain-language feature list,
then keep contributor/build/internals as a clearly separated secondary section.

* docs(desktop): fix install framing — releases no longer auto-build installers

Lead with the install-with-Hermes path (`--include-desktop` / `hermes desktop`),
which always works, and describe prebuilt installers as manually published when
a release ships them rather than implying CI attaches them to every release.

* docs(desktop): match base repo README style

Adopt the root README's conventions: centered title + badge row, bold
one-liner intro, a feature <table> grid, --- section dividers, and a
Community / License footer.

* feat(desktop): recover from gateway boot failures + validate API keys on entry (#35864)

Fresh installs that hit a gateway boot failure had no recovery path: the
shell rendered dead ("gateway offline"), logs were undiscoverable, and a
mistyped API key was accepted because onboarding only checked credential
presence, not validity.

- Add BootFailureOverlay: a top-level recovery surface (Retry, Repair
  install, Use local gateway, Open logs + inline recent logs) that mounts
  on any hard boot failure, including post-install. Trims the now-redundant
  recovery button from the onboarding Preparing panel.
- Add hermes:logs:reveal / :recent IPC (reveal desktop.log) and a
  hermes:bootstrap:repair IPC that drops the bootstrap marker to force a
  clean reinstall. Surface "Open logs" in Gateway settings too.
- Add POST /api/providers/validate: a live per-provider probe
  (OpenRouter/OpenAI/xAI/Gemini key check, local endpoint connectivity)
  wired into saveOnboardingApiKey so a rejected key blocks before it's
  persisted, while an unreachable probe falls through (offline-safe).

* test(model-catalog): fix stale nous picker test after curated-list change

ac2e48907 made the GUI/picker Nous row use the curated list (curated["nous"]
= get_curated_nous_model_ids()) + Portal union, matching the `hermes model`
CLI — but test_picker_nous_row_uses_manifest still asserted the old 2-model
manifest snapshot, breaking the test shard.

Rewrite it as an invariant: stub the Portal union to passthrough and assert the
row equals get_curated_nous_model_ids() computed under the same conditions, so
it tracks the real contract instead of a hardcoded model list that rots on every
catalog update.

fix(tui): auto-recover session on unexpected gateway death (+ persist lifecycle breadcrumbs) (#35893)
* fix(tui): persist gateway lifecycle breadcrumbs to crash log

A backend SIGTERM (`=== SIGTERM received ===` in tui_gateway_crash.log) is
always a parent action — `gw.kill()` (graceful-exit on a signal to Node, or an
explicit /quit) or `start()` replacing a live child. #31051 added parent-side
lifecycle breadcrumbs but left them in an in-memory CircularBuffer that dies
with the process, so SIGTERM crash reports arrive with no parent context and no
way to tell a signal-driven kill from a memory-critical `process.exit(137)`
(which closes the child's stdin → clean EOF, not SIGTERM).

Persist the death-explaining breadcrumbs (spawn / transport-exit / child-exit /
replace-live-child / kill-reason / startup-timeout) plus the graceful-exit
signal name and the memory-critical exit into the same crash log the Python
side writes, so they interleave by timestamp next to the child's panic entry —
making these recurring reports diagnosable.

Gated off under VITEST so unit tests stay hermetic.

* feat(tui): auto-recover the session when the gateway dies unexpectedly

When a still-owned gateway child dies while the TUI is alive (a crash, OOM
process.exit, or a SIGTERM/SIGHUP forwarded to it), the app currently nulls the
session and drops to an inert "gateway exited" state — the user loses a long
session and has to restart + re-run everything. That single behavior is most of
the "TUI doesn't survive heavy work" complaint, independent of what does the
killing.

The 'exit' event only reaches this handler on an *unexpected* death: a user
/quit calls process.exit before it fires, and a replaced child is identity-
skipped in GatewayClient. So on exit we now respawn the gateway and resume the
session that was live (history is persisted in SQLite) via a one-shot
recoverSidRef the next gateway.ready consults before forging a new session. The
in-flight reply is lost (it died with the process) but the session survives.

Bounded to GATEWAY_RECOVERY_LIMIT (3) attempts per GATEWAY_RECOVERY_WINDOW_MS
(60s) so a gateway that crash-loops on startup can't spawn-storm; past the
budget we fall back to the inert state.

* fix(tui): sanitize newlines + soften SIGTERM-cause claim in parentLog

Address PR review:
- recordParentLifecycle collapses embedded \r\n so a multi-line value (e.g. an
  error message) stays a single breadcrumb and can't masquerade as a separate
  entry or as the child's panic output sharing the crash log.
- Reword the header: a backend SIGTERM is *usually* a parent action but can come
  straight from an external supervisor (s6, cgroup OOM, stray kill); the
  presence/absence of a [tui-parent] line before the child's panic is precisely
  what disambiguates the two.

* fix(tui): clear sid during recovery + extract/test the recovery budget

Address PR review:
- Null `sid` immediately in the gateway exit handler. While the gateway is down
  (busy=false) the old sid would otherwise let sid-guarded effects (the 1.5s
  session.active_list poll, queue drain) fire RPCs at a dead/respawning gateway.
  recoverSidRef carries the session forward; resumeById restores sid on ready.
- Extract the respawn budget into a pure evalRecovery() (gatewayRecovery.ts) and
  unit-test the bound: allows GATEWAY_RECOVERY_LIMIT within the window, blocks
  past it, and prunes attempts older than the window so recovery re-arms.

* fix(tui): cap parent-log breadcrumb length (PR review)

Truncate a single persisted breadcrumb to 4096 chars (matching GatewayClient's
in-memory log-line cap) so a pathological value — e.g. a giant error string —
can't bloat the shared crash log or add noticeable blocking on the synchronous
append during a failure path. Covered by a test.

* fix(tui): keep "recovering session…" status visible during resume (PR review)

resumeById() synchronously sets status to 'resuming…' on entry, so the
recovery branch now applies its 'recovering session…' label *after* calling
resumeById — the distinct label sticks for the duration of the resume RPC
(which later flips to 'ready') instead of being immediately clobbered. Test
updated to assert the ordering.

* fix(tui): keep recovery budget alive across a startup crash-loop (PR review)

deadSid was read from getUiState().sid, which the first exit nulls — so if the
respawned gateway crash-looped before gateway.ready (resumeById never restored
sid), later exits saw null and abandoned the session after a single attempt,
defeating the bounded retry budget.

Lift the whole decision into a pure planGatewayRecovery() that falls back to the
pending recoverSidRef target when the live sid is already cleared, and unit-test
the crash-loop sequence (keeps retrying the same session up to the limit, then
falls back to inert). Supersedes evalRecovery.

* chore(tui): drop non-null assertion + clarify breadcrumb cap comment (PR review)

- Recovery branch guards on `recoverSidRef && recoverSid` so the ref write needs
  no `!` assertion (avoids a future unsafe refactor).
- Reword the parentLog cap comment: it slices the value to 4096 chars and
  appends a short truncation marker (so the written line is slightly longer),
  rather than implying a strict 4096-byte limit.

* chore(tui): soften "absence ⇒ external signal" + "any in-flight reply" (PR review)

- parentLog header: a missing [tui-parent] line only *suggests* an external
  signal (the logger is best-effort: VITEST-disabled, failed append swallowed),
  not a definitive conclusion.
- Recovery notice says "any in-flight reply was lost" since the gateway can also
  exit while idle.

fix(tui): clamp bogus terminal dimensions (WSL 131072x1) (#35657)
Some hosts (notably WSL) report a junk window size such as 131072 columns
by 1 row. Both the Ink fork and our components only guard against
0/null/undefined/NaN (stdout.columns || 80), so a positive-but-absurd
width sails through into createScreen(width*height), allocating tens to
hundreds of MB per frame and tripping the TUI memory monitor's hard exit.

Add clampStdoutDimensions(), installed in entry.tsx before ink.render: it
patches process.stdout.columns/rows with clamping getters (cols 1-2000,
rows 1-1000; out-of-range -> 80x24). One install point fixes the renderer,
its resize handler, and every component read. Live resizes still propagate
through the original descriptor, just clamped.

64998fa93e fix(tui): use base64 encoding for PowerShell clipboard writes to preserve UTF-8
When writing text to the clipboard via PowerShell (WSL2 and native Windows),
the previous implementation piped text through stdin using `Set-Clipboard
-Value $input`. PowerShell reads stdin using the Windows system's default
ANSI code page (e.g. CP936 for Chinese Windows), causing all non-ASCII
characters (CJK, emoji, accented) to become garbled.

Fix: encode the text as base64 in Node.js and pass it as a command argument.
PowerShell decodes it from base64 using explicit UTF-8, bypassing the code
page issue entirely.

* fix(tui): delineate assistant responses from details

Add a muted Response marker before assistant text when thinking/tool details are visible so reasoning and final output do not visually run together.

* fix(tui): account for response separator height

Keep virtual transcript estimates aligned with the new response separator and avoid allocating trimmed copies of long assistant text.

* fix(tui): gate response separator estimate on details

Only add response-separator height when assistant details actually render, and use a non-allocating body-text check.

* fix(tui): skip empty detail height estimates

Do not add virtual transcript height for assistant details when no thinking or tool detail UI will render.

0277194e3b fix(tui): preserve transcript tail across resizes
Wraps + heights are column-dependent, so a width change must remeasure
every row and the renderer must repaint the full viewport.

- Key virtualRows on cols so React remounts wrapped rows on resize.
- Snap back to bottom after sticky-mode resize once React rerenders.
- Reserve a scrollbar + gap column in transcriptBodyWidth (non-termux).
- Full repaint on any viewport height change (was: shrink-only).

d08c2a016a fix(tui): termux-gate composer rendering tweaks for Ink TUI
Salvaged from #28942 (adybag14-cyber). Only the Ink TUI half is taken
here — the bundled "termux compatibility note" added to skills_tool.py
in the original PR did not address the actual user-reported bug
(skill_matches_platform() filtering Linux skills out on Termux) and
also regressed the EXCLUDED_SKILL_DIRS set used to prune nested
.venv/site-packages skills.

Changes:
- ui-tui/src/lib/prompt.ts: single-cell ASCII '>' marker in Termux mode
  to avoid ambiguous-width glyph artifacts while typing.
- ui-tui/src/components/appLayout.tsx: suppress profile prefix on
  narrow Termux panes (>=90 cols still shows it).
- ui-tui/src/lib/inputMetrics.ts + components/messageLine.tsx +
  lib/virtualHeights.ts: termux-aware transcript body width — drop
  the desktop 20-col floor on narrow mobile layouts, align virtual
  heights with actual rendered width.
- ui-tui/src/components/textInput.tsx: disable fast-echo bypass by
  default in Termux to avoid ghosting at soft-wrap boundaries.
  HERMES_TUI_TERMUX_FAST_ECHO=1 opts back in.

Tests: ui-tui/src/__tests__/{prompt,termuxComposerLayout,textInputFastEcho}.test.ts
(12 PR-added tests pass; 3 pre-existing wrapAnsi-bundling failures on
main are unrelated.)

The real skill-listing fix on Termux ('android' platform matching
Linux skills) ships as a follow-up commit on this branch.

fix(tui): anchor splitReasoning unclosed-tag regex to start of input (#29426)
`splitReasoning()` strips paired `<think>…</think>` blocks first, then runs
an unclosed-trailing regex to catch reasoning that hasn't yet streamed its
closer. That second regex was unanchored and greedy:

    new RegExp(`<${tag}>([\\s\\S]*)$`, 'i')

So any literal `<think>` somewhere in prose — a model quoting the tag, a
code example, or a stream-mid-tag before the closer arrives — consumed
every paragraph after it to EOF. User-visible symptom: "TUI eats last
paragraph of output," both during streaming and on settled turns.

Real reasoning streams always lead the message (that's the only place an
unclosed opener can legitimately appear during streaming). Anchor the
regex to `^\s*` so mid-prose mentions of the tag are preserved.

Empirical repro before the fix:

    splitReasoning('final answer paragraph one.\n\n<think>internal note\n\nfinal answer paragraph two.')
    → text: 'final answer paragraph one.'        ← paragraph two GONE

After:

    → text: 'final answer paragraph one.\n\n<think>internal note\n\nfinal answer paragraph two.'

Updated the existing trailing-unclosed test to lead with `<think>` (the
real-world shape) and added a regression test pinning the mid-text case.

ui-tui type-check clean, 808/808 vitest pass.

7c2ff742a4 fix(tui): termux-gate scrollback preservation, touch-friendly defaults
Adds a Termux runtime detection helper and gates three TUI defaults on it:

- Skip the startup scrollback clear on Termux so users can review/copy
  earlier output after reopening the app. Desktop keeps the existing
  \x1b[2J\x1b[H\x1b[3J slate (AlternateScreen takes over there anyway).
- Default INLINE_MODE on under Termux: primary-buffer rendering makes
  long-thread review and copy/paste much less fragile when users
  background/foreground the app. Override with HERMES_TUI_INLINE=0/1.
- Default mouse tracking off under Termux so touch selection isn't
  intercepted by terminal mouse protocols. Explicit override via
  HERMES_TUI_MOUSE_TRACKING=0/1; legacy HERMES_TUI_DISABLE_MOUSE still
  works on desktop.

Detection is purely env-based (TERMUX_VERSION or PREFIX path) with an
explicit opt-out HERMES_TUI_TERMUX_MODE=0 for debugging. Non-Termux
platforms keep every existing default.

8c78f533dd review(tui): route cursorLayout through @hermes/ink wrapAnsi shim (Bun runtime parity)
Copilot caught an important runtime parity gap on PR #27489: the fix
imported the npm `wrap-ansi` package directly, but Ink's `<Text
wrap="wrap">` uses a runtime-selecting shim
(`ui-tui/packages/hermes-ink/src/ink/wrapAnsi.ts`) that prefers
`Bun.wrapAnsi` when running under Bun and falls back to the npm package
elsewhere. So under Bun, Ink would render via `Bun.wrapAnsi` while
`cursorLayout` would compute breaks via the npm package — any
disagreement reintroduces the exact cursor-drift symptom the PR is
meant to eliminate.

Fix:

- Export `wrapAnsi` from `@hermes/ink` (`packages/hermes-ink/src/entry-exports.ts`
  and `packages/hermes-ink/index.d.ts`) so the shim is the public surface.
- Switch `ui-tui/src/lib/inputMetrics.ts` from `import wrapAnsi from
  'wrap-ansi'` to `import { wrapAnsi } from '@hermes/ink'`. Both
  renderer (Ink) and cursor layout now traverse the same shim, so
  they share the runtime-selected implementation by construction.
- Same swap in `textInputWrap.test.ts` and `cursorDriftRegression.test.ts`
  — tests now assert parity through the shim, which means under Bun
  they actually exercise Bun's implementation instead of asserting a
  tautology against the npm package.
- Drop the direct `"wrap-ansi": "^9.0.0"` from `ui-tui/package.json`.
  `@hermes/ink` (which IS a declared dep) pulls wrap-ansi in
  transitively — that's not a phantom dep because the import path
  goes through `@hermes/ink`'s public exports, not through a
  hoisting accident.

Verified: 791/791 vitest tests pass. `@hermes/ink` rebuilt
(`dist/entry-exports.js` includes `wrapAnsi` export). TUI bundle
rebuilt clean.

1c0e59e557 review(tui): address Copilot feedback on cursorLayout wrap-ansi rewrite
Three small follow-ups from the Copilot review on #27489:

1. Declare `wrap-ansi` as a direct dependency of `ui-tui`. It was a
   phantom dep that resolved via npm hoisting from `@hermes/ink`'s
   transitive graph — fine on hoisted installs, but breaks under pnpm
   or `npm install --no-install-strategy=hoisted` style isolated
   installs. Now listed as `"wrap-ansi": "^9.0.0"` matching the
   @hermes/ink version. Lockfile regenerated.

2. Implement the defensive resync the comment promised. Previously the
   comment claimed the loop would "fall back to advancing by one to
   stay in lockstep" on wrap-ansi desync, but the code unconditionally
   advanced `originalIdx` with no actual check — so any future
   wrap-ansi option change or styled-input caller could silently slide
   `originalIdx` past the end of `value` and emit garbage line ranges.
   Now actually compares `value[originalIdx] === ch`, re-syncs via
   `indexOf` on mismatch, and bails out (returning whatever was built
   so far) if the desync is unrecoverable. Production paths still hit
   the equality fast-path on every char.

3. Drop the `visualLines` wrapper. It was a one-line indirection over
   `visualLinesFromWrappedOutput`. Renamed the implementation to
   `visualLines` and removed the wrapper — same name, no extra layer.

No behavior change beyond the defensive realign; all 791 vitest tests
still pass.

3b4dd68326 fix(tui): align composer cursorLayout with wrap-ansi to kill multiline cursor drift
The composer's `cursorLayout` (in `ui-tui/src/lib/inputMetrics.ts`) used a
hand-rolled word-wrap algorithm to decide where `useDeclaredCursor`
should park the hardware cursor. But Ink's `<Text wrap="wrap">` renders
the same text via `wrap-ansi`. The two algorithms disagreed on common
real-world inputs — `"branch investigate"` at cols=20, `"hello world"`
at cols=8, exact-fill strings like `"abcdefgh"` at cols=8 — so the
hardware cursor parked several cells past where Ink actually rendered
the last character. Users saw a multi-cell blank gap between their
last-typed letter and the cursor block, especially on narrow terminals
(the Cursor IDE built-in terminal was the worst offender).

Three previous PRs (#26717, #25860, #22197) chased fast-echo
displayCursor/cursorDeclaration drift and in-band-vs-native cursor
heuristics. None of them touched the underlying wrap-algorithm
mismatch, which is why the bug kept resurfacing.

Fix: source cursorLayout's line breaks from wrap-ansi directly. Walk
its emitted string char-by-char, tracking original-string offsets, push
a VisualLine at each '\n'. Also drop the buggy `column >= w` overflow
rule in cursorLayout — that's what pushed exact-fill text onto a
phantom next row.

canFastBackspaceShape now detects the wrap boundary in BOTH coordinate
conventions (column === 0 OR column >= columns), since exact-fill now
reports as (0, columns) instead of the previous (1, 0). The physical
state is identical — the terminal auto-wraps at column N either way —
but the layout function reports the position more honestly.

Tests:
- ui-tui/src/__tests__/textInputWrap.test.ts: 3 tests that pinned the
  BUGGY behavior were updated to assert wrap-ansi parity (the real
  invariant). Added a typing-prefix invariant: cursorLayout must agree
  with wrap-ansi at every character of a long input.
- ui-tui/src/__tests__/cursorDriftRegression.test.ts: new file. Walks
  the user-reported bug message char-by-char at 7 widths and asserts
  agreement with wrap-ansi at every prefix.

Verification:
- 791/791 vitest tests pass.
- 84/84 tui-gateway pytest tests pass via scripts/run_tests.sh.
- PTY repro (typing into a real `hermes --tui` PTY at cols=50/55/60):
  cursor lands exactly 1 cell past the last typed char in every case
  the bug previously drifted.

tui: make URLs clickable + hover-highlight in any terminal (#25071)
* tui: make URLs clickable + hover-highlight in any terminal

Problem
-------
URLs printed by `hermes --tui` were not clickable in basic macOS Terminal.app.
Cmd+click did nothing, the cursor didn't change shape — like nothing was
detected — even though arrow buttons and other Box onClick handlers worked
fine.

Root cause
----------
Two layers of dead plumbing:

1. `<Link>` only emitted the underlying `<ink-link>` (which carries the
   hyperlink metadata into the screen buffer) when `supportsHyperlinks()`
   said yes. On Apple_Terminal that's false, so the per-cell hyperlink
   field stayed empty, so `Ink.getHyperlinkAt()` had nothing to return on
   click. The visible underline was just decorative.

2. `Ink.openHyperlink()` calls `this.onHyperlinkClick?.(url)`, but
   `onHyperlinkClick` was never assigned anywhere in the codebase. The
   click pipeline (`App.tsx → onOpenHyperlink → Ink.openHyperlink`) ran
   but bailed silently on the optional chain.

Bonus discovery: even when wired up, there was no hover affordance —
terminal apps can't change the system mouse cursor, so users had no
visual signal that a cell was clickable. Arrow buttons in the chrome
worked because they had explicit `<Box onClick>` styling; inline link
URLs didn't.

Fix
---
- `Link.tsx`: always emit `<ink-link>` regardless of terminal capability.
  The renderer's `wrapWithOsc8Link` already gates the actual OSC 8 escape
  on `supportsHyperlinks()` further down — so terminals that don't
  understand OSC 8 still don't see the escape, but the screen-buffer
  metadata (which the click dispatcher reads) is now populated everywhere.

- `ink.tsx + root.ts`: add `onHyperlinkClick?: (url: string) => void` to
  `Options` / `RenderOptions`, wire it to the existing `Ink.onHyperlinkClick`
  field in the constructor.

- `src/lib/openExternalUrl.ts`: small platform-aware opener using
  `child_process.spawn` with arg-array (no shell) — http(s) only, rejects
  `file:`, `javascript:`, `data:`, etc., so a hostile model can't trigger
  arbitrary local handlers via `<Link url="file:///...">`. Detached + stdio
  ignore so closing the TUI doesn't kill the browser and Chrome stderr
  doesn't leak into the alt screen.

- `entry.tsx`: pass `onHyperlinkClick: openExternalUrl` to `ink.render`.

- `hyperlinkHover.ts` + Ink hover wiring: track the URL under the pointer
  in `Ink.hoveredHyperlink`, update it from `dispatchHover`, and inverse-
  highlight every cell of the matching link in the render-pass overlay
  (same pattern as `applySearchHighlight`). This is the cursor-hover
  affordance for clickable links — terminals don't expose cursor shape,
  so we light up the link itself.

- `types/hermes-ink.d.ts`: add `onHyperlinkClick` to the `RenderOptions`
  shim so consumers (`entry.tsx`) type-check against the new option.

Tests
-----
- `src/lib/openExternalUrl.test.ts` (15 cases): http(s) accepted; file/js/
  data/mailto/ftp/ssh rejected; macOS open(1), Windows cmd.exe start with
  empty title slot, Linux xdg-open dispatch; shell-metacharacter URLs
  pass through unmolested as a single argv element; synchronous spawn
  failure returns false.

Verified empirically in Apple Terminal 455.1 (macOS 15.7.3): clicking a
URL opens in default browser, hovering inverts the link cells, and
moving away clears the highlight. Full TUI suite: 713 passing, 0
type errors.

Reverts
-------
The earlier attempt that version-gated Apple_Terminal in
`supports-hyperlinks.ts` was based on a wrong assumption — Terminal.app
silently strips OSC 8 sequences but does not render them as clickable
hyperlinks. Reverted to the original allowlist.

* tui: address Copilot review — explorer.exe on win32 + comment fixes

- openExternalUrl: switch win32 from `cmd.exe /c start` to `explorer.exe`.
  cmd.exe's `start` builtin reparses the URL through cmd's tokenizer, so
  `&`, `|`, `^`, `<`, `>` either split the command or get reinterpreted —
  breaking both the protocol-allowlist safety story AND plain http(s) URLs
  with `&` in query strings. `explorer.exe <url>` invokes the registered
  protocol handler directly with no shell.

- openExternalUrl.test.ts: rename the win32 test to reflect the new
  contract and add two regression tests — one with `&|^<>` metachars,
  one with the common analytics-URL `&` query-param pattern — both pinned
  to single-argv-element delivery via explorer.exe.

- Link.tsx: fix misleading comment. OSC 8 escapes are emitted
  unconditionally by the renderer (`wrapWithOsc8Link` in
  render-node-to-output.ts, `oscLink` in log-update.ts). Non-supporting
  terminals silently strip the sequence, which is why hover/click
  affordance has to come from the in-process overlay rather than the
  terminal's own link rendering.

Verified: 715/715 tests pass, type-check + build clean.

* tui: address Copilot review #2 — async spawn errors + hover scope + docs

1. openExternalUrl: attach a no-op `'error'` listener on the spawned
   child BEFORE unref(). spawn() returns a ChildProcess synchronously
   even when the binary is missing (ENOENT on xdg-open / explorer.exe),
   unreachable, or otherwise unusable; the failure surfaces later as
   an 'error' event. An unhandled 'error' on an EventEmitter crashes
   Node, which would tear down the whole TUI. The listener is a
   deliberate no-op — we already returned `true` synchronously and the
   user just doesn't see the browser pop.

2. openExternalUrl.test.ts: add a regression test using a real
   EventEmitter to simulate the async-error path. Pins both the
   listener-attached contract and the "doesn't throw on emit" behavior.
   Was 17/17, now 18/18.

3. ink.tsx dispatchHover: bypass `getHyperlinkAt()` and read
   `cellAt(...).hyperlink` directly. `getHyperlinkAt` falls back to
   `findPlainTextUrlAt` for cells without an OSC 8 hyperlink, but the
   render-pass overlay (`applyHyperlinkHoverHighlight`) only matches on
   `cell.hyperlink === hoveredUrl` — so plain-text URLs would burn
   re-renders without ever producing the highlight. Hover is now a
   strictly 1:1 fit for what the overlay can paint. Plain-text URLs
   still get the click action via the existing dispatch path.

4. root.ts + ink.tsx doc comments: replace the misleading "typically
   `open` / `xdg-open` / `start` shell" wording with the actual safe
   recipe — argv-array spawn into `open` / `xdg-open` / `explorer.exe`,
   with an explicit warning that `cmd.exe /c start` reparses the URL
   through cmd's tokenizer and is unsafe + breaks `&`-query URLs.

Verified: 716/716 tests pass, type-check + build clean.

* tui: address Copilot review #3 — hover damage, alt-screen cleanup, opener allowlist

1. ink.tsx onRender: stop folding steady-state hover into hlActive.
   hlActive forces a full-screen damage diff so previous-frame inverted
   cells get re-emitted when the highlight set changes. The transition
   IS the trigger — enter / leave / change-to-other-link. While the
   pointer just sits on a link the painted cells don't change and the
   per-cell diff handles the no-op. Folding the steady state in would
   burn a full-screen diff on every frame. Added a
   lastRenderedHoveredHyperlink tracker and gate the hlActive bump on
   `hovered !== lastRendered`.

2. ink.tsx setAltScreenActive: clear hoveredHyperlink (and the tracker)
   when toggling alt-screen state. Hover dispatch is alt-screen-gated,
   so once we leave there's no path to clear it. Without this, remounting
   <AlternateScreen> would paint a phantom hover from the previous
   session until the next mouse-move arrived.

3. openExternalUrl.ts openCommand: allowlist linux + the BSD family for
   xdg-open and return null for everything else (aix, sunos, cygwin,
   haiku, etc.). Previously the default-fallback always returned
   xdg-open, which made the caller's `if (!command) return false` dead
   and yielded a misleading `true` on platforms that probably don't
   have xdg-open. New tests cover the null path AND the
   openExternalUrl-returns-false-without-spawning behavior.

Verified: 718/718 tests pass, type-check + build clean.

* tui: address Copilot review #4 — doc comment accuracy

1. openExternalUrl return-value doc: now lists all three false paths
   (URL rejected / no opener for platform / synchronous spawn throw)
   plus a note that async 'error' events still return true because the
   spawn was attempted.

2. ink.tsx onHyperlinkClick field doc: clarifies the callback receives
   either an OSC 8 hyperlink OR a plain-text URL detected by
   findPlainTextUrlAt — App.tsx routes both into the same callback.

3. hyperlinkHover applyHyperlinkHoverHighlight doc: drops the misleading
   'caller forces full-frame damage' promise. Caller decides; for hover
   the current caller only forces full damage on transitions.

No behavior change. 718/718 tests pass.

* tui: address Copilot review #5 — lint fixes

1. ink.tsx: reorder `./hyperlinkHover.js` import before `./screen.js` to
   satisfy perfectionist/sort-imports.

2. Link.tsx: drop unused `fallback` parameter destructuring + the
   trailing `void (null as ...)` dead-statement (would trip
   no-unused-expressions). Kept `fallback?: ReactNode` on the Props
   interface as a documented compat shim so existing call sites still
   compile, with a comment explaining why it's no longer wired up.

3. openExternalUrl.test.ts: replace `typeof import('node:child_process').spawn`
   inline annotations (forbidden by @typescript-eslint/consistent-type-imports)
   with a `SpawnLike` type alias backed by a real `import type { spawn as SpawnFn }`.

No behavior change. 718/718 tests pass, type-check clean, lint clean on
all modified files.

feat(tui): segment turns with rule above non-first user msgs; trim ticker dead space (#21846)
Multi-turn transcripts ran together visually because every user message
got the same vertical rhythm regardless of position. Adds a short ─── in
the border colour above every user message after the first, so each turn
reads as its own block. Height estimator gains a `withSeparator` flag so
virtual scrolling pre-allocates the extra two rows (rule + top margin)
and avoids a jump on first measurement.

While in the area: the busy-indicator duration was padded with
`padStart(7)`, leaving five visible spaces between `·` and the digits
(`⠋ ·      2s`) — especially loud under the verb-less `unicode` style.
Drop the padding entirely (`⠋ · 2s`); the model label now shifts a few
columns as the duration grows, which is the right trade-off for the
minimal indicator styles. The verb-padding test stays; the
duration-padding test is removed alongside the function it covered.

fix(tui): respect voice.record_key config (supersedes #19028, #19339) (#19835)
* fix(tui): respect voice.record_key config instead of hardcoded Ctrl+B

Classic CLI loaded ``voice.record_key`` from config.yaml and bound the
prompt-toolkit handler dynamically (``cli.py`` paths). The new TUI hard-
coded ``Ctrl+B`` everywhere — ``isVoiceToggleKey`` (input handler),
``/voice status`` ("Record key: Ctrl+B"), and ``/voice on`` ("Ctrl+B to
start/stop recording"). A user who set ``voice.record_key: ctrl+o``
(or any other key) saw the documented config silently ignored — only
Ctrl+B worked, the displayed shortcut lied about it.

Wire the configured key end to end through the existing channels:

* **Backend** (``tui_gateway/server.py``): ``voice.toggle`` action=status
  AND action=on/off responses now include ``record_key``, sourced from
  ``config.get('voice', {}).get('record_key', 'ctrl+b')``.
* **Backend types** (``ui-tui/src/gatewayTypes.ts``): ``ConfigFullResponse``
  now exposes ``config.voice.record_key`` and ``VoiceToggleResponse``
  carries ``record_key`` so the TUI can both bind and display it.
* **Frontend parser/formatter** (``ui-tui/src/lib/platform.ts``):
  ``parseVoiceRecordKey()`` accepts ``ctrl+b`` / ``alt+r`` / ``cmd+space``
  and the common aliases (``option``, ``cmd``, ``win``, …); falls back to
  the documented Ctrl+B for empty / multi-character / malformed input so
  a typo never silently disables the shortcut. ``formatVoiceRecordKey()``
  renders for status text. ``isVoiceToggleKey`` now takes a parsed
  ``ParsedVoiceRecordKey`` argument; the hardcoded ``ch === 'b'`` is
  gone. Default arg keeps existing call sites back-compat.
* **Hydration** (``ui-tui/src/app/useConfigSync.ts``,
  ``useMainApp.ts``): startup ``config.get full`` already runs; extract
  ``cfg.voice.record_key`` from it, parse, push into a new
  ``voiceRecordKey`` state, and forward to the input handler ctx
  (``InputHandlerContext.voice.recordKey``). Mtime-poll path also
  re-applies the parsed key so a hand-edit of config.yaml takes effect
  the next tick — matches existing behaviour for display options.
* **Input handler** (``ui-tui/src/app/useInputHandlers.ts``):
  ``isVoiceToggleKey(key, ch, voice.recordKey)`` so the configured
  binding fires.
* **Slash command** (``ui-tui/src/app/slash/commands/session.ts``):
  ``/voice status`` and ``/voice on`` use ``formatVoiceRecordKey`` on
  the response's ``record_key`` instead of the hardcoded label.

Tests:
* ``parseVoiceRecordKey`` covers ctrl/alt/cmd/super aliases, multi-char
  rejection, and empty fallback.
* ``formatVoiceRecordKey`` covers the doc examples (``Ctrl+B``,
  ``Ctrl+O``, ``Alt+R``, ``Cmd+B``).
* ``isVoiceToggleKey`` regression: ``ctrl+o`` configured → only ``o``
  matches, not ``b``; ``alt+r`` matches both alt-bit and meta-bit
  encodings (terminal protocol parity); omitted-arg call still binds
  Ctrl+B for back-compat.

Full TUI suite (555 tests) passes; ``tsc --noEmit`` clean.

Fixes #18994

* fix(tui): support named-key tokens in voice.record_key (space, enter, …)

Reviewer caught that the round-1 parser in #18994 rejected every
multi-character token, so a config value like ``ctrl+space`` (which the
CLI happily binds via prompt_toolkit's ``c-space`` rewrite in
``cli.py``) silently fell back to the documented Ctrl+B default —
re-introducing the same false-shortcut bug the PR was meant to fix,
just at a different surface.

Add explicit named-key support that mirrors what the CLI accepts:

* ``space``         (alias: ``spc``)        → matches ``ch === ' '``
* ``enter``         (alias: ``return``, ``ret``) → matches ``key.return``
* ``tab``                                   → matches ``key.tab``
* ``escape``        (alias: ``esc``)        → matches ``key.escape``
* ``backspace``     (alias: ``bs``)         → matches ``key.backspace``
* ``delete``        (alias: ``del``)        → matches ``key.delete``

``ParsedVoiceRecordKey`` gains an optional ``named`` field; ``ch``
holds either a single char (back-compat) or the canonical named token,
and the runtime matcher dispatches on ``named`` before checking the
modifier shape. Aliases collapse to one canonical name so
``ctrl+esc`` and ``ctrl+escape`` behave identically.

Unrecognised multi-character tokens (e.g. ``ctrl+spcae`` typo, or
unsupported keys like ``ctrl+f5``) still fall back to the Ctrl+B
default rather than silently disabling the binding — keeps the "typo
never silently kills the shortcut" guarantee.

Tests:

* ``parseVoiceRecordKey`` parametrised over every named token + each
  alias variant.
* New ``isVoiceToggleKey`` cases for space (ch-based match), enter
  (``key.return``), tab, escape, backspace, delete, including
  modifier-mismatch negatives.
* ``formatVoiceRecordKey`` renders named keys in title case
  (``Ctrl+Space``, ``Ctrl+Enter``).
* Existing fall-back-to-Ctrl+B contract preserved for empty input
  AND unrecognised multi-char tokens.

Full TUI suite: 559/559 pass; ``tsc --noEmit`` clean.

* test(tui): assert voice.toggle returns configured record_key

Salvage the backend regression from #19339 — asserts ``voice.toggle``
action=on AND action=status responses carry the configured
``voice.record_key`` end-to-end through ``_load_cfg()``. Keeps the
CLI→TUI parity contract visible in the Python test suite alongside
the existing frontend parser/matcher/formatter coverage from #19028.

* fix(tui): address Copilot review on #19835 voice.record_key wiring

Five tightenings on the parser + matcher + hydration surface, all
caught by the Copilot review on the PR — each one turns a silent
false-fire or display/binding skew into a deterministic behaviour.

* **isVoiceToggleKey ctrl branch was too permissive for named keys.**
  The doc-default macOS Cmd+B muscle-memory fallback
  (``isActionMod(key)`` on top of ``key.ctrl``) fired for every
  configured key, so bare Esc — which hermes-ink reports with
  ``key.meta`` on some macOS terminals — triggered ``ctrl+escape``,
  and Alt+Space / Alt+Tab triggered ``ctrl+space`` / ``ctrl+tab``.
  Gate the fallback to the literal ``ctrl+b`` binding so any custom
  chord requires the real Ctrl bit.
* **Alt branch guarded against Ctrl/Cmd co-press.** Without this,
  Ctrl+Alt+<letter> and Cmd+Alt+<letter> also fired ``alt+<letter>``.
* **Dropped the ``meta`` modifier variant and its alias.** In
  hermes-ink ``key.meta`` is Alt on xterm-style terminals and Cmd on
  legacy macOS ones, so a literal ``meta+b`` config displayed as
  ``Cmd+B`` while matching Alt+B — exactly the kind of false
  shortcut the PR was meant to remove. ``cmd`` / ``command`` now
  collapse onto ``super`` (kitty-style ``key.super``, with a macOS
  ``key.meta`` fallback) and render as ``Cmd+B``. Unknown modifier
  tokens fall back to the documented Ctrl+B default rather than
  silently coercing to Ctrl.
* **Slash-command display/binding skew.** ``/voice status`` and
  ``/voice on`` rendered from the fresh gateway ``record_key``
  response, but ``useInputHandlers()`` still bound the old key
  until the next 5s mtime poll. Thread ``setVoiceRecordKey``
  through ``SlashHandlerContext.voice`` and push the parsed spec
  into frontend state on every response so text and binding stay
  consistent.
* **Test coverage for the two paths Copilot flagged.** Added
  vitest coverage for (a) the three-case ``/voice`` slash output
  in ``createSlashHandler.test.ts`` and (b) the
  ``applyDisplay → voice.record_key`` hydration + omit-setter
  back-compat paths in ``useConfigSync.test.ts``. Plus regression
  cases for every false-fire scenario above.

Suite: 575/575 green, tsc --noEmit clean.

* fix(tui): address Copilot round-2 review on #19835

Three tightenings on the surface introduced in the round-1 fix:

* **``/voice tts`` reset custom bindings to Ctrl+B.** The ``tts`` branch
  of ``voice.toggle`` omitted ``record_key`` from its response, so the
  frontend's ``r.record_key ?? 'ctrl+b'`` coerced a user's custom
  binding back to the default on every TTS toggle. Two-sided fix:
  the backend now includes ``record_key`` on the ``tts`` branch (parity
  with ``status``/``on``/``off``), and the slash handler only pushes
  frontend state when the response actually carries ``record_key`` —
  belt-and-suspenders against any future branch forgetting to include
  it.

* **``super+b`` / ``win+b`` / ``cmd+b`` displayed "Cmd+B" on Linux and
  Windows.** ``formatVoiceRecordKey`` rendered ``mod === 'super'`` as
  ``Cmd`` universally, which told non-mac users the wrong modifier to
  press even though ``isVoiceToggleKey`` matched the right event bits.
  Gate the label to ``isMac`` so non-mac renders ``Super+B``.

* **``control+b`` / ``ctrl + b`` lost the macOS Cmd+B fallback.**
  ``_isDefaultVoiceKey`` keyed off ``parsed.raw`` — so
  semantically-equal aliases of the documented default dropped into
  the strict branch even though they bind Ctrl+B. Compare on the
  parsed spec (mod + ch + named) instead.

Coverage added: Linux ``Super+B`` rendering (and macOS ``Cmd+B``),
``control+b`` / ``ctrl + b`` accepting the Cmd+B fallback on darwin,
``/voice tts`` without ``record_key`` not clobbering cached binding,
and a backend regression asserting every ``voice.toggle`` branch
carries the configured key.

* fix(tui): address Copilot round-3 review on #19835

Three classes of robustness issue caught on the second pass — all
revolve around malformed YAML tipping ``parseVoiceRecordKey`` or
``_voice_record_key`` into a crash instead of the documented
fallback.

* **Parser crashed on non-string YAML scalars.** ``config.get full``
  returns raw ``yaml.safe_load`` output, so ``voice.record_key: 1``
  or ``voice.record_key: true`` in a hand-edited config would hit
  ``.trim()`` on a number/bool and throw, breaking startup and
  every mtime re-apply. Accept ``unknown`` at the signature, guard
  with ``typeof raw !== 'string'``, and fall back to the default.

* **Backend blew up on non-dict ``voice:``.** Same YAML hazard on
  the gateway side: ``voice: true`` / ``voice: cmd+b`` left
  ``_load_cfg().get("voice")`` as a bool/str, so ``.get("record_key")``
  raised AttributeError and took every ``voice.toggle`` branch down
  with it. Centralised the lookup in a single
  ``_voice_record_key()`` helper that ``isinstance``-guards both
  ``voice`` and ``record_key`` and falls back to ``ctrl+b``.

* **Multi-modifier chords silently dropped extras.** The previous
  validator only checked the first modifier token, so ``ctrl+alt+r``
  silently parsed as ``ctrl+r`` and ``cmd+ctrl+b`` as ``super+b`` —
  a typo bound a different shortcut than the user configured.
  Reject multi-modifier spellings outright; the classic CLI only
  supports single-modifier bindings via prompt_toolkit's ``c-x`` /
  ``a-x`` rewrite, so this matches CLI parity.

Coverage added:

* ``parseVoiceRecordKey`` fallback on ``1`` / ``true`` / ``null`` /
  ``undefined`` / ``{}``.
* ``parseVoiceRecordKey`` fallback on ``ctrl+alt+r`` /
  ``cmd+ctrl+b`` / ``alt+ctrl+space``.
* ``test_voice_toggle_handles_non_dict_voice_cfg`` exercises
  every non-dict ``voice:`` shape (bool, str, None, int, list) and
  asserts each falls back to ``record_key: 'ctrl+b'``.

Suite: 581/581 TUI vitest green, 3/3 backend voice tests green,
tsc --noEmit clean.

* fix(tui): address Copilot round-4 review on #19835

Four final corners of the voice.record_key surface:

* **Bare-char configs silently coerced to ``ctrl+<key>``.** A config
  like ``voice.record_key: o`` / ``space`` / ``escape`` fell through
  to the default ``mod = 'ctrl'`` and silently bound Ctrl+O, while
  the classic CLI's prompt_toolkit would bind the raw key (no
  rewrite) — so the two runtimes silently disagreed on what "o"
  means. Require an explicit modifier; bare-char configs fall back
  to the documented Ctrl+B default.

* **Reserved ctrl+<letter> bindings would never fire.**
  ``useInputHandlers()`` intercepts ``ctrl+c`` (interrupt),
  ``ctrl+d`` (quit), and ``ctrl+l`` (clear screen) before the voice
  check runs, so those configs would be advertised in /voice
  status but the advertised shortcut never actually triggers
  push-to-talk. Added ``_RESERVED_CTRL_CHARS`` at parse time so
  the user gets the documented default instead of a dead shortcut.
  (``alt+c``, ``cmd+l``, etc. are not intercepted and stay usable.)

* **``_load_cfg()`` root itself may be a non-dict.**
  ``_voice_record_key()`` isinstance-guarded the ``voice`` subkey
  but not the root — a malformed config.yaml that collapsed to a
  scalar/list at the top level (``config.yaml: true`` or ``[]``)
  would still raise on ``.get("voice")``. Added the top-level
  guard too so every malformed shape falls back to ``ctrl+b``.

* **Stale header comment on ``isVoiceToggleKey``.** The doc-comment
  still claimed "On macOS we additionally accept the platform
  action modifier (Cmd) for the configured letter" even though the
  implementation gates the Cmd fallback to the documented default
  only. Rewrote to match.

Coverage added:

* ``parseVoiceRecordKey`` fallback on bare chars (``o``, ``b``,
  ``space``, ``escape``).
* ``parseVoiceRecordKey`` fallback on ``ctrl+c`` / ``ctrl+d`` /
  ``ctrl+l``; positive case for ``alt+c`` / ``cmd+l`` still usable.
* Backend ``test_voice_toggle_handles_non_dict_voice_cfg`` now
  exercises 5 non-dict shapes at the YAML root too.

* fix(tui): address Copilot round-5 review on #19835

Three follow-ups on the voice matcher's modifier + shift discipline:

* **``super`` branch falsely fired on Alt+<key> / bare Esc on macOS.**
  ``isVoiceToggleKey`` accepted ``isMac && key.meta`` as a Cmd
  fallback for the ``super`` modifier — but hermes-ink sets
  ``key.meta`` for plain Alt/Option AND for bare Escape on some
  macOS terminals. A ``cmd+b`` config silently fired on Alt+B;
  ``cmd+space`` on Alt+Space; ``cmd+escape`` on bare Esc. Drop the
  fallback and require the literal ``key.super`` bit. Legacy-
  terminal users who need Cmd should upgrade to a kitty-protocol
  terminal or bind ``alt+X`` explicitly.

* **Shift bit was never checked.** The parser rejects multi-
  modifier configs like ``ctrl+shift+tab``, but the runtime
  matcher didn't check ``key.shift`` — so ``ctrl+tab`` also fired
  on Ctrl+Shift+Tab and ``alt+enter`` on Alt+Shift+Enter.
  Early-return on ``key.shift === true`` so the runtime only fires
  the exact chord the user configured.

* **Test leaked ``HERMES_VOICE=1`` into later tests.**
  ``voice.toggle`` action=on writes to ``os.environ`` directly
  (CLI parity, runtime-only flag); ``test_voice_toggle_returns_
  configured_record_key`` dispatched action=on without letting
  monkeypatch take ownership of the var first. Any later test
  that read voice mode in the same Python process could inherit a
  stale enabled state. Added ``monkeypatch.setenv("HERMES_VOICE",
  "0")`` up front so monkeypatch restores the original value at
  teardown.

Coverage added:

* ``cmd+b`` / ``cmd+space`` / ``cmd+escape`` do NOT fire on
  ``key.meta``-only events on darwin.
* ``ctrl+tab`` / ``alt+enter`` / ``ctrl+o`` reject matches when
  ``key.shift`` is held; sanity cases without Shift still fire.

* fix(tui): address Copilot round-6 review on #19835

Three classes of modifier-discipline tightening + one config-surface
honesty fix:

* **Default ``ctrl+b`` Cmd fallback leaked Alt+B.** The default's
  macOS Cmd+B muscle-memory path used ``isActionMod(key)``, which
  returns ``key.meta || key.super`` on darwin. hermes-ink also
  reports plain Alt as ``key.meta``, so Alt+B silently fired the
  default binding. Replaced with strict ``isMac && key.super ===
  true`` — kitty-style Cmd+B still works, Alt+B correctly
  rejected. Legacy-terminal mac users (Terminal.app without
  CSI-u) now get raw Ctrl+B only; the documented default still
  works everywhere.

* **ctrl / super branches accepted extra modifier bits.** The
  parser rejects multi-modifier configs like ``ctrl+alt+o``, but
  the runtime matcher was permissive — ``ctrl+o`` fired on
  Ctrl+Alt+O / Ctrl+Cmd+O, and ``super+b`` fired on Cmd+Alt+B /
  Ctrl+Cmd+B. Added strict ``!key.alt && !key.meta && key.super
  !== true`` on ctrl, and ``!key.ctrl && !key.alt && !key.meta``
  on super, so the runtime only fires the exact chord the parser
  would let you configure.

* **Dropped ``cmd`` / ``command`` aliases.** They parsed to
  ``super`` and rendered as ``Cmd+X``, but legacy macOS terminals
  report Cmd as ``key.meta`` (same signal as Alt), so a
  ``cmd+o`` config was advertised as working but never actually
  fired on Terminal.app-without-CSI-u. That recreated the
  "displayed shortcut does not work" problem this PR was meant to
  remove. Users who want the platform action modifier spell it
  ``super`` / ``win`` — that matches the unambiguous ``key.super``
  bit, and kitty-style macOS terminals render it as ``Cmd+X`` via
  platform-aware formatter.

Coverage updated:

* Default ctrl+b no longer fires on Alt+B via ``key.meta`` leak;
  raw Ctrl+B and kitty-style Cmd+B still fire.
* ``ctrl+o`` rejects Ctrl+Alt+O / Ctrl+Cmd+O / Ctrl+Meta+O chords.
* ``super+b`` rejects Cmd+Alt+B / Cmd+Meta+B / Ctrl+Cmd+B chords.
* ``cmd+b`` / ``command+b`` / ``meta+b`` all fall back to the
  documented default at parse time (joined the ambiguous-mac-mod
  rejection class).
* Round-2 expectations that asserted ``cmd+b`` parsed as super
  and accepted ``key.meta`` on darwin updated to reflect the new
  stricter contract.

* fix(tui): address Copilot follow-up on wire typing + escape precedence

Two follow-ups from the latest Copilot pass:

* **Config wire typing honesty (`gatewayTypes.ts`)**
  `config.get full` forwards raw `yaml.safe_load()` output, so
  `voice.record_key` can be any scalar/container when hand-edited.
  Typing it as `string` suggests a normalized contract that the
  backend does not guarantee and makes unsafe callers more likely.
  Change `ConfigVoiceConfig.record_key` to `unknown` with an
  explicit comment that callers must normalize at runtime.

* **Escape-based voice bindings were swallowed before voice check**
  `useInputHandlers()` handled `key.escape` for queue-edit cancel and
  selection clear before `isVoiceToggleKey(...)`, so configured
  `ctrl+escape` / `alt+escape` / `super+escape` chords were advertised
  but never toggled recording in those UI states.
  Add an early escape+voice check before generic Esc handlers so
  escape-based voice bindings win when configured, while plain Esc
  behavior remains unchanged.

Also updated PR #19835 description text to remove stale cmd/command
alias claims and match the current parser contract.

* fix(tui): pass configured voice shortcut through TextInput layer

Thread the live parsed voiceRecordKey into TextInput so configured voice.record_key chords bubble to useInputHandlers instead of being consumed as editor input. This removes the last hardcoded Ctrl+B pass-through in the composer path while preserving existing global control chord behavior.

* fix(tui): require explicit alt bit for escape-based alt chords

Hermes-ink reports bare Escape as meta=true+escape=true on some terminals, so a configured alt+escape binding was firing on bare Esc. Require an explicit key.alt bit when the configured named key is escape so plain Esc stays plain Esc; kitty-style alt+escape still fires.

* fix(tui): harden voice.record + TextInput paste + super-mod reserved list

Three round-7 Copilot follow-ups on #19835:

- voice.record start handler used _load_cfg().get('voice', {}).get(...) without
  shape checks, so malformed YAML (bool/scalar/list) returned 5025 instead of
  using VAD defaults. Centralized _voice_cfg_dict() helper and type-guarded
  silence_threshold/silence_duration with numeric fallbacks.
- TextInput pass-through check moved above paste/copy handling so configured
  voice chords (ctrl+v / alt+v / cmd+v) beat the composer's paste/copy
  defaults.
- parser now also rejects super+{c,d,l,v} — on macOS those are
  copy/exit/clear/paste and would be advertised in /voice status but never
  actually toggle recording.

* fix(tui): round-8 Copilot review — allow ctrl+x, gate super reservations to macOS, preserve voice key on transient RPC failure

Three round-8 Copilot follow-ups on #19835:

- Revert ctrl+x addition to _RESERVED_CTRL_CHARS (landed via Copilot Autofix
  commit 731ec86): ctrl+x is only claimed during queue-edit
  (queueEditIdx !== null), so voice works the rest of the session and
  matches CLI ctrl+<letter> parity.
- Gate super+{c,d,l,v} reservation to isMac. Linux/Windows TUI globals key
  off Ctrl, so kitty/CSI-u super+<letter> configs don't collide on non-mac
  and should stay usable.
- applyDisplay() now skips setVoiceRecordKey when cfg is null so one
  transient quietRpc() failure after a config edit doesn't clobber the
  cached binding back to Ctrl+B until the next successful poll.

New coverage:
- parseVoiceRecordKey preserves ctrl+x on linux
- super+{c,d,l,v} rejected on darwin, allowed on linux
- applyDisplay(null, ...) leaves voiceRecordKey untouched

* fix(cli,tui): normalize voice.record_key aliases across CLI + TUI for parity

Round-9 Copilot review on #19835: TUI accepted control+/option+/opt+/super+/win+ aliases but the classic CLI only rewrote literal ctrl+/alt+ before handing to prompt_toolkit, so a TUI-valid config silently bound a different (or no) shortcut in the CLI.

- Added normalize_voice_record_key_for_prompt_toolkit() in hermes_cli/voice.py with a single alias table (ctrl/control/alt/option/opt → c-/a-).
- Wired it into all three cli.py sites (_enable_voice_mode hint, _show_voice_status display, and the prompt_toolkit binding in _register_voice_handler).
- /voice status display now renders control+x as Ctrl+X and option+x as Alt+X (canonical casing) to match TUI formatVoiceRecordKey.
- super/win/windows are intentionally left unchanged: prompt_toolkit has no super modifier, so the CLI will reject them loudly at startup rather than silently binding Ctrl+B. Documented this split at both the TUI _MOD_ALIASES comment and the CLI normalizer docstring.
- Added tests covering ctrl/control/alt/option/opt mapping, case-insensitivity, non-string fallback, empty-string fallback, and super/win pass-through.

* fix(cli): port TUI parser contract into CLI voice.record_key normalizer

Round-10 Copilot review on #19835.

hermes_cli/voice.py's normalize_voice_record_key_for_prompt_toolkit() previously did blind substring replacement with no trim/validate step, so the CLI diverged from the TUI parser on:
- whitespace ('ctrl + b' -> 'c- b' instead of 'c-b')
- typoed named keys ('ctrl+spcae' passed through as 'c-spcae' and prompt_toolkit would reject at startup)
- bare-char configs ('o' should fall back, not pass through as 'o')
- multi-modifier chords ('ctrl+alt+r')
- reserved ctrl chars ('ctrl+c/d/l')
- unknown modifiers ('meta+b' / 'shift+b')
- named-key aliases ('return'/'esc'/'bs'/'del' not collapsed to prompt_toolkit canonicals)

Port the TUI parser contract into Python (_VOICE_MOD_ALIASES, _VOICE_NAMED_KEYS, _VOICE_RESERVED_CTRL_CHARS) so one config value binds the same shortcut in both runtimes.

Also added format_voice_record_key_for_status() shared between the PTT hint and /voice status display. Non-string scalars (voice.record_key: true / 1) now surface as 'Ctrl+B' instead of the raw scalar — /voice status no longer advertises a shortcut that can never bind.

Tests: 29/29 in test_voice_wrapper.py, including 11 new regressions covering whitespace, named-key aliases, typos, bare-char, multi-modifier, reserved ctrl, unknown mods, non-string fallback, and formatter contract.

* fix(cli): shape-safe voice config read + graceful super/win fallback

Round-11 Copilot review on #19835.

Two remaining cross-runtime gaps:

1. load_config().get('voice', {}) still assumed voice was a dict, so a hand-edited voice: true / voice: cmd+b at the top level raised AttributeError before the voice UI could start. Added voice_record_key_from_config(cfg) to hermes_cli/voice.py that isinstance-guards both the root and the voice subkey. All three cli.py read sites (_enable_voice_mode hint, _show_voice_status, PTT binding) now use it.

2. The CLI normalizer previously passed super+/win+/windows+ through unrewritten so prompt_toolkit would reject them loudly at startup — but that crash was a worse UX than a silent fallback. Normalizer now returns c-b for those spellings, and the PTT binding site logs a warning so users see why their TUI-only shortcut isn't binding in the CLI.

Coverage: 34/34 in tests/hermes_cli/test_voice_wrapper.py (5 new cases for voice_record_key_from_config + malformed-root + malformed-voice + extractor/normalizer composition).

* fix(cli): self-audit cleanup — remaining voice-config shape safety + doc drift

Self-review of the voice.record_key change set turned up four remaining items Copilot would very likely flag next round:

1. cli.py _voice_start_continuous still read load_config().get('voice', {}).get('silence_threshold') without an isinstance guard, so a hand-edited voice: true / voice: cmd+b (non-dict) raised AttributeError on VAD recording start. Shape-safe coerce the voice dict and numeric-guard silence_threshold/silence_duration.

2. cli.py _enable_voice_mode's auto_tts check had the same bug — fixed with the same isinstance guard.

3. hermes_cli/voice.py module comment on _VOICE_MOD_ALIASES still said super/win/windows 'pass through unchanged and prompt_toolkit's add() call loudly rejects them at startup'. Round 11 changed the normalizer to silently fall back to c-b with a warning at the binding site; updated the comment to match.

4. ui-tui/src/lib/platform.ts header comment had the same stale 'CLI will loudly reject them at startup' claim; updated to 'falls back to the documented default and logs a warning'.

No behavior change on the code paths already covered by test_voice_wrapper.py; the two cli.py fixes are defensive against malformed YAML that previous rounds already hardened in tui_gateway/server.py but missed in the classic CLI.

* fix(cli,tui): round-12 Copilot review — alt-collide on mac, bool-in-int guards, voice UI hardcodes, mtime-reload test

Five round-12 Copilot review items on #19835:

1. platform.ts: hermes-ink reports Alt as key.meta on many terminals; isActionMod on darwin accepts key.meta as the action modifier. So alt+c/d/l get claimed by isCopyShortcut / isAction('d')/'l') before the voice check. Reject those configs at parse time on macOS only (non-mac keeps them usable).

2. cli.py: four remaining hardcoded 'Ctrl+B' sites in voice-facing UI (_get_voice_status_fragments status bar, _voice_start_recording hints, _get_placeholder composer text) were still lying about non-default configs. Added self._voice_record_key_label() shared helper and wired it into all three sites.

3. server.py + cli.py: bool is a subclass of int, so isinstance(silence_threshold, (int, float)) accepted True/False from malformed YAML and forwarded 1/0 to the VAD engine. Exclude bool explicitly so boolean typos fall back to the documented 200 / 3.0 defaults.

4. useConfigSync.ts: extracted the config.get-full fetch+apply body into a shared hydrateFullConfig() helper. Both the initial hydration and mtime-reload paths now use it, so the polling/RPC wiring is exercised by direct unit tests (4 new cases: fresh apply, reapply on new value, transient RPC failure preserves cache, back-compat without voice setter).

5. Added alt+{c,d,l} rejection regressions on darwin + allow on linux, and bool-leak regressions for both silence_threshold and silence_duration in tests/test_tui_gateway_server.py.

Suite: 602/602 TUI vitest, 38/38 backend voice tests, typecheck + lints clean.

* fix(cli): cache voice record-key label at binding time + status-bar coverage

Round-13 Copilot review on #19835.

_voice_record_key_label() was reading live config on every render, which caused two problems:

1. prompt_toolkit registers the push-to-talk binding once at session start (@kb.add(_voice_key)); the binding does NOT re-read config. Editing voice.record_key mid-session would switch the status-bar / placeholder / recording-hint label to the new shortcut while the actual keybinding stayed on the startup chord — reintroducing the display/binding drift this whole PR is fighting.

2. Hot render path: during recording the UI is invalidated every 150ms, so re-loading + deep-merging config on every call added avoidable UI overhead.

Fix: cache the label at the same site that registers the prompt_toolkit binding via new set_voice_record_key_cache(raw_key). _voice_record_key_label() now just returns the cached value (falls back to 'Ctrl+B' before startup). Status/placeholder/hint are always in sync with the live binding; no config reload per render.

Also added 4 regression cases to tests/cli/test_cli_status_bar.py: configured ctrl+<letter> renders in both wide and compact status bars, configured named key (ctrl+space) renders in the recording hint, pre-startup absent cache falls back to Ctrl+B, and malformed configs (bool True) fall through the formatter to Ctrl+B.

Suite: 60/60 test_cli_status_bar + test_voice_wrapper, typecheck + lints clean.

* fix(cli): route /voice on + /voice status through startup-pinned label; mac alt+cdl parity

Round-14 Copilot review on #19835. All three comments legit:

1. _enable_voice_mode still formatted label from live load_config() — mid-session config edit would make /voice on announce the new shortcut while the prompt_toolkit binding stayed the startup chord. Use self._voice_record_key_label() (cached at binding time, round-13) so /voice on cannot drift from the live binding.

2. _show_voice_status had the same bug — /voice status reported live config instead of the pinned startup binding. Fixed the same way.

3. CLI normalizer accepted alt+c/alt+d/alt+l even though the TUI parser rejects them on macOS (Copilot round-12 — hermes-ink reports Alt as key.meta, isActionMod on darwin accepts it, collides with isCopyShortcut / isAction). Added _VOICE_RESERVED_ALT_CHARS_MAC = {c,d,l} gated to sys.platform == 'darwin' so a shared config like option+c falls back to c-b on both runtimes on macOS; non-mac still binds a-c.

Coverage: 4 new tests in test_voice_wrapper.py covering mac alt+cdl rejection, linux alt+cdl allowed, option/opt alias forms, and mac-specific exclusions for other alt letters. 62/62 in voice wrapper + status bar suites.

fix(goals): make /goal work in TUI and fix gateway verdict delivery (#19209)
/goal was silently broken outside the classic CLI.

TUI: /goal was routed through the HermesCLI slash-worker subprocess,
which set the goal row in SessionDB but then called
_pending_input.put(state.goal) — the subprocess has no reader for that
queue, so the kickoff message was discarded. No post-turn judge was
wired into prompt.submit either, so even a manual kickoff would not
continue the goal loop. Intercept /goal in command.dispatch instead,
drive GoalManager directly, and return {type: send, notice, message}
so the TUI client renders the Goal-set notice and fires the kickoff.
Run the judge in _run_prompt_submit after message.complete, surface
the verdict via status.update {kind: goal}, and chain the continuation
turn after the running guard is released.

Gateway: _post_turn_goal_continuation was gated on
hasattr(adapter, 'send_message'), but adapters only expose send().
That branch was dead on every platform — users never saw
'✓ Goal achieved', 'Continuing toward goal', or budget-exhausted
messages. Replace the dead call with adapter.send(chat_id, content,
metadata) and drop a broken reference to self._loop.

Tests:
- tests/tui_gateway/test_goal_command.py — full /goal dispatch matrix
  (set / status / pause / resume / clear / stop / done / whitespace)
  plus regressions for slash.exec → 4018 and 'goal' staying in
  _PENDING_INPUT_COMMANDS.
- tests/gateway/test_goal_verdict_send.py — locks in the adapter.send
  path for done / continue / budget-exhausted and verifies the hook
  no-ops when no goal is set or the adapter lacks send().

71c8ca17dc chore(salvage): strip duplicated/merge-corrupted blocks from PR #17664
Removes drive-by duplication that accumulated during the contributor
branch's multiple rebases. All runtime-benign (dict last-wins,
redefinition last-wins) but left dead source that would confuse
reviewers and maintainers.

Surgical in-place de-duplication (kept PR's intentional additions,
removed only the doubled copy):

* hermes_cli/auth.py: duplicate "gmi" + "azure-foundry" ProviderConfig
* hermes_cli/models.py: duplicate "gmi" entry in _PROVIDER_MODELS
* hermes_cli/config.py: duplicate NOTION/LINEAR/AIRTABLE/TENOR skill env
  block + duplicate get_custom_provider_context_length definition
* hermes_cli/gateway.py: duplicate _setup_yuanbao
* gateway/platforms/base.py: duplicate is_host_excluded_by_no_proxy
* gateway/platforms/telegram.py: duplicate delete_message
* gateway/stream_consumer.py: duplicate _should_send_fresh_final and
  _try_fresh_final
* gateway/run.py: duplicate _parse_reasoning_command_args /
  _resolve_session_reasoning_config / _set_session_reasoning_override,
  duplicate "Drain silently when interrupted" interrupt check
* run_agent.py: duplicate HERMES_AGENT_HELP_GUIDANCE append, duplicate
  codex_message_items capture, duplicate custom_providers resolution
* tools/approval.py: duplicate HARDLINE_PATTERNS section and duplicate
  hardline call in check_dangerous_command
* tools/mcp_tool.py: duplicate _orphan_stdio_pids module-level decl
* cron/scheduler.py: duplicate "not configured/enabled" check — kept
  the new early-rejection, removed the stale late-path copy
