Rewrite of the paradigm, not just a cheaper version of it. Before, any file
mutation bumped a contentless $workspaceChangeTick and the tree re-read EVERY
loaded directory to diff — the parent state was never told what actually changed.
Now the mutation carries its path:
- workspace-events accumulates the changed dir(s) (dirname of an absolute tool
path) and exposes consumeWorkspaceChange(); an opaque mutation (terminal, or a
relative/unresolvable path) sets `full` instead.
- gateway-event passes toolChangedPath(payload) through on tool.complete.
- revalidateTree(cwd, change) re-reads ONLY the changed dirs that are loaded and
patches just those subtrees — root + untouched folders never hit the FS or
re-render. Full recursive reconcile is kept as the fallback for `full`.
So a write in one folder no longer crawls the whole tree; the opaque terminal
case still self-heals via the full path. Safe fallback everywhere a path can't be
resolved, so no change is ever missed.
typecheck + eslint clean; use-project-tree / right-sidebar / gateway-events tests green.
revalidateTree runs on every $workspaceChangeTick (mutating-tool completion,
coalesced ~500ms). Two costs per tick, gone:
1. clearProjectDirCache() wiped the gitroot + gitignore caches. But listings are
read fresh every time (readProjectDir never caches them), so the wipe bought
nothing except forcing a full re-read of every ancestor .gitignore — each a
full readdir — for every loaded dir, every tick. Dropped; a .gitignore edit is
still picked up on the next full refresh (cwd/connection change / manual).
2. reconcile awaited each child dir serially, crawling a wide/deep tree one dir
at a time. Now Promise.all over siblings (order preserved), recursing per
loaded subfolder.
use-project-tree.test.ts + right-sidebar/index.test.tsx green (15). tsc + eslint clean.
Selecting a large changed file in the review pane froze it: FileDiffPanel with
no fullText + no showLineNumbers rendered SyntaxDiff over EVERY line — a full
Shiki highlight + thousands of mounted DOM nodes — because windowing was tied to
showLineNumbers/fullText and the review call had neither.
Decouple windowing from the gutter:
- `windowed = showLineNumbers || virtualized`; windowed paths always render the
fixed-row chunked body (TokenizedDiffBody chunked / PreviewDiffRows), never
SyntaxDiff, so only visible rows mount.
- New `virtualized` prop → windowed scroller WITHOUT the line-number gutter.
- Review passes `virtualized` + the preview's fill className.
Preview (showLineNumbers + fullText) and tool-card (compact) render byte-for-byte
as before — the gutter body just reads the same chunked window it already used,
and the no-fullText+highlight case (previously SyntaxDiff) now windows too.
tsc + eslint clean. Visual paths preserved by construction; needs an in-app
eyeball on a large review diff.
One shared `stableArray(prev, next)` helper replaces the duplicated
element-equal/keep-prev logic in both stores, and freezes the shared ref so a
future in-place mutation fails loud instead of silently corrupting the cache.
Computed return type is now `readonly string[]` (it always was, immutably).
* feat(desktop): add custom endpoint settings (supersedes #42745)
Salvages PR #42745 (elashera:custom-endpoints-desktop), which could no
longer merge cleanly against main. Re-integrated the work onto current
main and reconciled the conflicts:
- Settings nav: wired the new 'Custom Endpoints' provider sub-view into
main's data-driven navGroups/OverlayNav layout (PR predated that
refactor) and added it to PROVIDER_VIEWS.
- providers-settings: kept BOTH main's LocalEndpointRow affordance and
the PR's fuller CRUD panel; unified ProvidersSettingsProps to carry
onClose + onConfigSaved + onMainModelChanged.
- web_server: kept main's _normalize_main_model_assignment + api_key
propagation AND the PR's provider base_url lookup in
_apply_model_assignment_sync.
- model_switch: dropped the PR's bare direct-custom-config picker block;
main already implements it (source='model-config', with live model
discovery). Updated the salvaged test to assert main's behavior.
- Merged additive import/type blocks in hermes.ts and types/hermes.ts.
Backend endpoints, i18n labels (en/ja/zh/zh-hant), and the
custom-endpoints-settings.tsx panel carried over. 28 custom-endpoint
tests pass.

Salvaged and rebased from #66354 by @UnathiCodex onto current main.
Fixes a fresh-chat race in Hermes Desktop where a model, reasoning-effort,
or Fast selection made before the first Send could be replaced by an
in-flight profile refresh, or read only after the profile handshake
yielded. Send is now the linearization point: the visible selector state is
snapshotted before awaiting profile readiness, and intent-generation guards
make older config/model responses stand down after a picker/toggle action.
Adds the contract-v4 session-create wire contract for explicit Fast=false.
Conflict resolution vs the original branch (use-model-controls.ts / .test.tsx):
combined main's catalog-aware keepManualPick() sticky-pick logic with the
PR's profileRefreshEpoch + composerSelectionGeneration staleness guards so
both a removed-from-catalog reseed and the in-flight-picker race are handled.
Verified on current main: apps/desktop tsc --noEmit clean; 80 affected
UI/store tests pass (use-model-controls, use-hermes-config,
use-session-actions, model-edit-submenu, model-presets, updates).

* fix(desktop): allow write-build-stamp from non-git checkouts
Stop hard-failing npm pack when neither GITHUB_SHA nor git HEAD is
available (ZIP installs / broken .git). Emit an explicit fallback stamp
instead so local Windows desktop builds can finish (#50823).
* fix(desktop): treat fallback stamps as unpinned; harden Windows install
Keep all-zero fallback commits out of -Commit/--commit pins and fetch
install.ps1 by branch instead. After bootstrap, pin the marker to the
checkout HEAD so isBootstrapComplete accepts it. On Windows, force ZIP
checkout, seed GITHUB_SHA (ASCII-only install.ps1), and avoid the pack
stamp failure.
* fix(install): pin core.autocrlf=false before ZIP-path checkout (#50823 review)
The ZIP-fallback path added in #67643 runs `git checkout -f FETCH_HEAD`
before core.autocrlf gets pinned (which only happened later, on the
shared clone-path config). On Git for Windows -- where core.autocrlf
defaults to true -- that renormalizes the repo's LF text files to CRLF in
the working tree during checkout, leaving the freshly-created managed
checkout dirty versus HEAD and aborting the next `hermes update`. That is
the exact "dirty tree the user never touched" failure the surrounding
code already guards against (install.ps1:1461-1469, 1750-1753).
Move the `config core.autocrlf false` pin to run immediately after
`git init`, before the fetch/checkout. The later idempotent pin on the
shared clone path is retained so git-clone installs are unaffected.
Addresses teknium1's review on #67643 and supersedes it, preserving the
original author's two commits.

Two real render-cost wins found by inspection (no behavior change):
1. Sidebar re-rendered on every stream token. $sessionStates is republished on
every message delta (tens/sec during a turn), and the derived ID computeds
($workingSessionIds, $attentionSessionIds, $backgroundRunningSessionIds)
allocated a fresh array each time. nanostores notifies on !==, so the whole
ChatSidebar + every mounted row re-rendered per token even when the working/
attention/background set was unchanged. Return the previous array reference
when the contents match → nanostores skips the notify unless the set actually
changes. Turns streaming from O(visible rows)/token into O(0) for the sidebar.
2. Tool rows normalized the FULL uncapped detail every render. `looksRedundant`
(lowercase + whitespace-collapse over the entire read_file/terminal payload)
ran twice in the ToolEntry render body, so every completed tool re-normalized
its whole output on every stream tick of the running message. Memoize on the
view fields so it recomputes only when the tool's content changes.
Both are correctness-preserving (stable refs + memoization). The CI stream
scenario drives $messages directly, not the publishSessionState path, so it
won't reflect #1 — verified by inspection.
Profiling the boot answered "is there a real cold-start win?": no wasteful
hotspot — the renderer does only ~tens of ms of work at mount, no heavy library
(shiki/mermaid/katex/d3/motion) initializes at startup; the rest is Electron
runtime + waiting, near the Electron floor.
It also exposed that the cold-start number was pessimistic: a fresh
--user-data-dir per run means a COLD V8 code cache and worst-case bundle
recompile every launch. Real users reuse their profile. Measured delta:
fresh (cold cache): spawn→interactive ~1.48s
reused (warm cache): ~1.0s
So representative launch is ~1.0s; only first-launch-after-install pays ~+400ms.
- coldStartSamples() reuses one profile (run 0 warms the cache, discarded;
runs 1..N are warm samples), stepping ports + pausing so the single-instance
lock releases. `--cold-fresh` measures the first-launch worst case.
- Re-baselined cold-start with the representative warm numbers.
Net: nothing high-ROI left to optimize. The only lever is shipping a pre-warmed
V8 code cache to make first launch match warm (~400ms, once per update) — real
packaging complexity for a marginal win, deliberately not pursued.
* bench(desktop): measure the full picture — prod build, cold-start, first-token
Stop drip-feeding scenarios: extend the harness to cover the latencies that
actually dominate perceived speed, and measure them on a REAL production build.
- --prod: build a production renderer with the probe included (VITE_PERF_PROBE=1,
off in normal builds) and launch it from dist/. Measures minified React, so
numbers are representative shipped figures instead of ~3x-inflated dev ones.
- cold-start scenario (tier "cold"): launch → CDP → driver → first paint, via a
fresh isolated spawn per run. Captures spawn_to_cdp_ms, spawn_to_driver_ms, fcp_ms.
- first-token scenario (backend tier): Enter → first assistant token painted —
the TTFT latency an agent app is uniquely judged on.
- run.mjs gained --prod (build once), cold-start fresh-spawn loop, and gates
ci+cold tiers against the baseline.
Baseline re-captured on a PRODUCTION build (median of 5), darwin-arm64 — all
green. Representative numbers:
cold-start spawn→interactive ~1.6s, FCP ~0.5s
stream frame p95 22ms, 1 longtask
keystroke p50 2ms, p95 8.7ms
transcript mount 145ms, 82ms longtask (400-msg open)
The prod build also settled the open question from the dev numbers: the
transcript-mount "lead" (221ms longtask in dev) is only ~72-82ms in prod — not
actionable. Measurement did its job.
* bench(desktop): trustworthy cold-start measurement (code-splitting is NOT the lever)
Investigated code-splitting the ~22MB renderer bundle to cut cold start. It is
the wrong fix on both counts:
1. Intentional design: vite.config disables codeSplitting because Shiki emits
thousands of dynamic chunks and electron-builder OOMs scanning them — a
packaging/installer constraint, not an oversight.
2. The data says it wouldn't help. Fixing the cold-start measurement to be
trustworthy and reading the boot composition (prod build):
spawn → interactive ~1.5s
renderer nav → DOMInteractive ~0.8s, → DOMContentLoaded ~1.06s
so the whole 22MB bundle EVAL is only ~0.27s (DCL − DOMInteractive) of the
~1.5s. The dominant costs are Electron/window startup and React app mount —
neither touched by splitting.
The measurement fixes (the real content of this PR — no app change, since the
optimization was rejected):
- Drop HERMES_DESKTOP_BOOT_FAKE from spawned instances — it injected artificial
per-phase boot-overlay sleeps that inflated cold-start (and slowed every run).
- Unique debug/dev port per cold-start run — a just-killed instance can hold
:9222 briefly, so reusing it made CDP attach to the DYING instance and report
garbage (spawn_to_cdp of ~4ms). Stepping the port per run fixes the race.
- Richer boot marks (dom_interactive, dom_content_loaded, main-script size) so
cold-start composition is visible, not just a single number.
- Forward all numeric boot marks from the cold-start loop.
- Re-baseline cold-start with the clean numbers.
A real cold-start win would target Electron startup / app-mount (e.g. V8 code
cache, deferred non-critical mount) — a future pass, now that it's measurable.
Stop drip-feeding scenarios: extend the harness to cover the latencies that
actually dominate perceived speed, and measure them on a REAL production build.
- --prod: build a production renderer with the probe included (VITE_PERF_PROBE=1,
off in normal builds) and launch it from dist/. Measures minified React, so

green. Representative numbers:

stream frame p95 22ms, 1 longtask
keystroke p50 2ms, p95 8.7ms

The prod build also settled the open question from the dev numbers: the
transcript-mount "lead" (221ms longtask in dev) is only ~72-82ms in prod — not
actionable. Measurement did its job.
Chased the "stream frame p95 = 60ms with ZERO longtasks" mystery to its actual
cause: the default stream chunk had no paragraph breaks, so it grew into one
giant ~22KB block that re-rendered fully every flush — defeating the block
memoization real streaming relies on. Plain text = 21ms; realistic chunk with
`\n\n` breaks (blocks settle, only the tail re-renders) = 23ms. Fixed the
default chunk to model real LLM output; a break-less `--chunk` remains available
as a single-block worst-case stress.
Also hardened the isolated instance so measurements reflect real cost:
- Wait for the gateway socket to actually connect before measuring (a booting/
absent backend's reconnect backoff churns the main thread). Exposed via a new
__PERF_DRIVE__.connected() probe reading $gateway.connectionState.
- Focus emulation + anti-throttle/occlusion flags so a backgrounded perf window
isn't frame-throttled (no OS focus stealing).
- Generation-guarded the rAF frame recorder so repeated runs don't leave
overlapping recorders polluting frame intervals.
Baseline re-captured as the median of 5 --spawn runs (darwin-arm64); all three
CI scenarios now green and stable. Absolute values are dev-build (noted in
_meta) — regression guards, not shipped numbers.
Add a color picker to the session menu (an Appearance submenu of reusable
ColorSwatches, in both the dropdown and right-click flavors). The pick is a
per-session override that wins over the inherited project color; clearing
falls back to it.
Storage is desktop-local like pins ($sessionColorOverrides persistentAtom),
keyed by the DURABLE lineage id so a color survives auto-compression's id
rotation. Precedence folds into the existing $sessionColorById resolver, so
sidebar rows AND pane tabs pick it up with no changes to either — the payoff
of the shared store. To take this to the TUI later, promote this one atom to
a backend SessionInfo.color field; the resolver and picker stay put.
- sessionColorFor: drop the no-op `?? undefined` (the map read is already
string | undefined).
- sessionProjectColor: fix a now-stale doc line — a rootless (no cwd AND no
git_repo_root) row returns null, not any cwd-less row (repo-root-only rows
resolve since the grouped-but-grey fix).
- ProjectMenu.applyAppearance: await instead of a .then block; flatten the
auto-branch's nested ternary.
- Resolve the vite CLI via vite/package.json `bin` (Vite 8's exports block
importing vite/bin/vite.js directly — --spawn failed with ERR_PACKAGE_PATH_NOT_EXPORTED).
- Add a post-launch settle so cold-start contention (vite dep pre-bundling,
first backend-connect attempts) doesn't contaminate the first scenario.
- Drop the raw autolink from the default stream chunk (resolvable URLs trigger
link-embed DNS lookups unrelated to render cost).
- Replace seed baseline with real numbers from a darwin-arm64 --spawn run.
keystroke + transcript are clean; stream is a clean single-run capture (the
isolated backend may not connect, and its reconnect churn inflates frame
pacing — re-capture on a connected instance for tighter tolerances).
simple-git's custom-binary validation rejects paths containing spaces, so
the default Windows Git install (C:\Program Files\Git\cmd\git.exe) made
every Review pane git call throw and the pane silently showed 'No diffs'.
The binary is resolved inside the Electron main process from known install
locations or PATH — never renderer/user input — so for spaced paths we opt
into simple-git's supported unsafe.allowUnsafeCustomBinary escape hatch
rather than falling back to PATH (often absent in GUI-launched apps).
Simplified from PR #64713 by @unsupportedpastels; supersedes the 8.3
short-path approaches in #55337/#60156.
Fixes#54888
Salvaged from #42654 by @digitalbase (earliest report of the leak, June 9):
the desktop sidebar and cron overlay showed EVERY profile's jobs because
GET /api/cron/jobs defaults to profile=all and the desktop never sent the
param — profileScoped() (landed in #67493) routes the backend process but
adds no endpoint filter on local pools.
- hermes.ts: getCronJobs(profile?) appends ?profile= when given; omitting
the arg keeps the legacy unfiltered path. profileScoped() still rides
along for process routing.
- use-session-list-actions.ts: sidebar cron refresh passes the sidebar's
profile scope (concrete profile → own jobs; ALL_PROFILES → 'all').
- app/cron/index.tsx: the cron overlay's refresh uses the same scope so
the overlay and sidebar (shared $cronJobs atom) always agree.
- Tests: list ?profile= contract in hermes-cron-scope.test.ts; sidebar
scoping in use-session-list-actions.test.tsx.
Reworked onto current main per the sweeper review: threaded through the
existing profileScoped()/list-param seams instead of the original PR's
pre-refactor call sites (DesktopController has since delegated to
use-session-list-actions).
Salvaged from #59888 by @isfttr: the profileScoped() fix itself landed
via #67493 (salvaged from the earlier #49948), but this PR contributed a
contract test locking all 9 cron helpers to the active gateway profile —
omitted when none is set (single-profile users unaffected), attached when
one is active. Keeps the multi-profile/remote cron routing from silently
regressing.
Salvaged from #49948 by @helix4u: every desktop cron API call
(list/get/runs/create/update/pause/resume/trigger/delete) now carries
profileScoped(), so global-remote mode routes the request to the profile
the UI is acting for instead of silently hitting the primary backend's
default profile.
* fix(desktop): stop contradicting the Ready pill with the one-time-install hint
When a provider's server-computed status is 'ready' (post_setup install
verifiably satisfied, e.g. cua-driver on PATH), the PostSetupRunner row
still said 'This backend needs a one-time install (…)'. Swap the copy for
a muted installed-confirmation one-liner and keep the Run setup button for
repair re-runs. Gated purely on the provider status prop so it composes
with the server-driven resting state work in the sibling lane.
* feat(tools): surface the web search/extract capability split in the Capabilities UI
The runtime has dispatched web_search and web_extract to independently
configurable backends for a long time (web.search_backend /
web.extract_backend overrides with web.backend as the shared fallback),
but the Capabilities tab still presented one monolithic 'Web Search &
Extract' choice that only wrote web.backend.
Backend:
- GET /api/tools/toolsets/web/config now returns active_search_backend /
active_extract_backend resolved via the REAL runtime getters
(tools.web_tools._get_search_backend/_get_extract_backend), plus each
provider row's web_backend key and supported capabilities (from the
registry's supports_search/supports_extract flags).
- PUT /api/tools/toolsets/web/provider accepts an optional capability
('search'|'extract') that writes web.<capability>_backend without
touching web.backend; validates the provider actually supports the
requested capability (ddgs/brave-free are search-only). Omitted →
unchanged legacy apply_provider_selection path.
- New tools_config.web_provider_capabilities() helper reads the plugin
registry's capability flags.
Frontend: 'Search: <backend>' / 'Extract: <backend>' pills above the web
provider matrix, per-row 'Search backend'/'Extract backend' assignment
pills, and 'Use for Search'/'Use for Extract' actions gated on each
backend's declared capabilities.
Tests: endpoint tests assert the runtime getters resolve to the written
backend (searxng for search, firecrawl for extract) after the endpoint
write; vitest covers badges, capability-gated buttons, and non-web
toolsets staying untouched.
* feat(desktop): deep-link Capabilities key rows to Settings → API Keys
Set env-var rows in the toolset config panel now offer 'Manage in API
Keys' in the row actions menu — an internal route change to
/settings?tab=keys&key=<ENV_KEY>. KeysSettings consumes the ?key= param
via the shared useDeepLinkHighlight hook (same mechanism as the command
palette's ?field= config deep links and ?session= archived-session
links): scrolls the credential card into view, flashes it, and expands
it. Applies generically to every env-var row, and only when the key is
set (unset keys are managed inline via Set). i18n in en/zh/zh-hant/ja.
* feat(desktop): point the vision Capabilities detail at Settings → Models
The vision toolset has no TOOL_CATEGORIES provider matrix — its
provider/model resolution runs through the auxiliary model config
(agent/auxiliary_client.py), so the Capabilities detail pane looked
empty with no hint of where the model choice lives.
Add a short explainer + an internal deep link
(/settings?tab=config:model&aux=vision) rendered only for
toolset.name === 'vision'. ModelSettings consumes the ?aux= param via
the shared useDeepLinkHighlight hook and scrolls/flashes the matching
auxiliary task row (rows now carry aux-task-<key> anchor ids). No
external URLs. i18n in en/zh/zh-hant/ja.
* test(desktop): use type-alias imports for the react-router mock (lint)
* chore: drop accidentally committed node_modules symlinks
* chore: drop remaining committed node_modules symlinks (apps/desktop, apps/shared)
The cron backend has always supported per-job model/provider pins (the
dashboard web UI and the cronjob tool expose them), but the desktop app's
cron editor had no way to set one — every job silently ran on the global
default model.
- Cron editor gains an optional Model select, grouped by provider, fed by
the same model.options catalog as the chat model picker (configured
providers with available models only, curated order preserved).
- Resetting to 'Default (global model)' clears a previous pin (model and
provider written as null); script-only (no_agent) jobs never touch the
model fields since the scheduler ignores overrides for them.
- A pinned model that has since left the catalog stays visible and
re-selectable instead of rendering Radix's blank trigger.
- Job detail pane shows the pinned model when one is set.
- ui/select grows SelectGroup + SelectLabel primitives for the grouped list.
- CronJob/CronJobCreatePayload/CronJobUpdates types carry model/provider;
en/ja/zh/zh-hant locales add the two new labels.
The cronjob model tool schema is intentionally unchanged — model selection
stays a user-facing UX affordance, not an agent-facing tool parameter.
* fix(windows): suppress console-window flash in tools post-setup subprocess spawns
The desktop GUI runs post-setup hooks via a detached, console-less
'hermes tools post-setup <key>' child (spawned with windows_detach_flags).
But the hook implementations in tools_config.py ran their inner installers
(npm install, agent-browser install, uv/pip installs, ensurepip, cua-driver
version probes and installer) without Windows creationflags — and on
Windows a console-less parent spawning a console/.cmd child materializes a
brand-new console window, the 'terminal flash' reported on the
Capabilities > Browser Automation setup journey.
Add _post_setup_no_window_flags(), a local wrapper around
windows_hide_flags() (CREATE_NO_WINDOW only — DETACHED_PROCESS would sever
stdio and break capture_output), and pass it at every post-setup subprocess
call site. Spawns that stream live output to the user's console
(verbose cua-driver install) only hide when stdout is not a tty, so
interactive CLI installs keep their output. POSIX behavior is unchanged
(the helper returns 0 off-Windows).
* fix(desktop): make Capabilities post-setup idempotent — Installed state instead of unconditional Run setup
The GUI panel rendered the primary 'Run setup' CTA whenever a provider
declared post_setup, ignoring the server-computed readiness status the
config endpoint already serves. Users on Windows clicked 'Run setup' on
an already-installed Local Browser and watched it 'install' again.
Frontend: PostSetupRunner now takes installed (provider.status === 'ready')
and renders an 'Installed' pill + small 'Re-run setup' text button in that
state; onComplete still refetches the toolset config, so a fresh install
flips the row to Installed once the endpoint reports ready.
Backend:
- _POST_SETUP_READY extended: agent_browser now tracks the FULL local
install (_local_browser_runnable: CLI + Chromium-or-Lightpanda) instead
of the bare CLI check; new entries for the cloud 'browserbase' hook
(CLI only — cloud rows host their own Chromium) and camofox (npm
package present).
- _run_post_setup prints distinct 'already installed, nothing to do'
messages for the agent-browser/Chromium/Camofox early-exits so the GUI
action log tells the truth on re-runs vs fresh installs.
i18n: new postSetupInstalled/postSetupRerun/postSetupInstalledHint strings
in en, ja, zh, zh-hant + types.
* fix(desktop): let managed Nous Subscription rows activate from the GUI via the Portal sign-in flow
PUT /api/tools/toolsets/{name}/provider intentionally skips the Nous
Portal auth gate the CLI runs inline (ensure_nous_portal_access) — but no
desktop surface handled it. Selecting 'Nous Subscription (Browser Use
cloud)' from Capabilities wrote browser.cloud_provider=browser-use +
use_gateway=true and then silently never activated: _is_provider_active
requires feature.managed_by_nous, which stays false without the
entitlement, and the credential was never used.
Backend: after apply_provider_selection, the endpoint now checks the
managed row's entitlement (get_nous_subscription_features force_fresh +
the same per-category coverage gate the CLI applies) and reports the gap
with additive response fields {needs_nous_auth: true, feature}. The
selection is still persisted — activation is what's gated.
Frontend: handleSelect surfaces a 'Sign in to Nous Portal' warning toast
with a Sign-in action instead of the misleading success toast. The action
drives the EXISTING Nous Portal OAuth device-code flow (provider id
'nous' in _OAUTH_PROVIDER_CATALOG): POST /api/providers/oauth/nous/start,
open verification_url, poll /poll/{session}; on approval the panel
refetches the toolset config so is_active/status flip.
i18n: nousAuthNeeded*/nousAuthSignIn/nousAuthDone*/nousAuthFailed strings
in en, ja, zh, zh-hant + types.
* feat(desktop): inherit project color on session rows
Sessions that belong to a colored project now pick up that color as the
sidebar row's idle lead dot, so work/personal/project buckets are legible
at a glance (Layer 1 of #66565). Derived from the same project membership
the sidebar already groups by; active states (working / needs-input /
background / unread) still own the dot so the tint never fights an
attention cue.
* feat(desktop): share session color across sidebar rows and pane tabs
Route session color through one computed store ($sessionColorById) that
both the sidebar rows and the pane tabs read, so a session and its tab can
never show different colors. Recomputed only when the session list or
projects change (cold atoms — the streaming pulse lives elsewhere) and read
as an O(1) lookup, never re-derived per render.
Tabs previously had no color at all: the strip renders only a title string.
Add a generic `accent` to the pane contribution that the tab strip paints as
a lead dot; the session tiles (via paneMirror) and the main workspace tab
(syncWorkspaceTitle) feed it from the same shared map. Precedence now lives
in one place, ready for per-session override / agent-set color (#66565).
* fix(desktop): resolve session color for repo-root-only sessions
liveSessionProjectId bailed the instant a session had no cwd, so an
older/imported session carrying only a git_repo_root — which the backend
still groups under its project — got no project and rendered a grey idle
dot instead of the project color ("grouped but grey"). Anchor on the repo
root when cwd is absent, matching how the sidebar grouped the row, and keep
the sibling-worktree guard for the cwd-present case.
Auto-detected git repos ("inherited" projects) have no projects.db row, so
their menu hid appearance/rename/etc. entirely and they could never be
themed. Add appearance to the auto-project menu: the first color/icon choice
adopts the repo as a real project (folder = repo root, name = its label)
carrying that look, after which it themes in place like any explicit
project. Routes both explicit and auto edits through one setProjectAppearance
helper; the picker closes on adopt so a stale second write can't double-create.
Replaces the dozen ad-hoc measure-*/profile-* scripts (each reinventing the
CDP client — 4 different copies — plus its own arg parsing, stats, output
path, and none with a baseline) with one framework under scripts/perf/:
- lib/cdp.mjs one CDP client + target discovery + typing + CPU-profile wrapper + DOM selectors
- lib/stats.mjs percentiles, histograms, CPU-profile self-time ranking
- lib/baseline.mjs load/compare/update baseline + regression gate (new capability)
- lib/launch.mjs attach, OR spawn a fully ISOLATED instance
- scenarios/* one module per measurement, registered in scenarios/index.mjs
- run.mjs / serve.mjs, baseline.json, README.md
Isolation solves the long-standing measurement blocker: a running `hgui` held
the Electron single-instance lock, so a second instance quit. `--spawn` /
`perf:serve` launch with their own --user-data-dir (separate lock scope), their
own HERMES_HOME (separate backend/sessions, config seeded from ~/.hermes so it
reaches a chat view without onboarding), and their own --remote-debugging-port.
Synthetic scenarios drive $messages via window.__PERF_DRIVE__, so no LLM credits.
Scenario -> sunset script mapping:
stream <- measure-synthetic-stream, profile-synth-stream, profile-long-stream
stream --real <- measure-real-stream, profile-real-stream
keystroke <- measure-latency, profile-typing, leak-typing
transcript <- (new: long-transcript mount cost)
submit <- measure-submit, measure-jump
session-switch <- profile-session-switch
profile-switch <- measure-profile-switch
CPU profiling is now a cross-cutting --cpuprofile flag, not 5 separate scripts.
CI-tier scenarios (stream, keystroke, transcript) need no backend/credits and
are gated against baseline.json (seed values; re-capture with --update-baseline
on a reference device). Backend-tier scenarios are report-only.
perf-probe.tsx gains loadTranscript() for the transcript scenario. No core
files touched; isolation is via CLI args, not env-gated app changes.
Verified: node --check all modules, tsc, eslint, and a unit smoke of the
stats + regression-gate logic. The end-to-end GUI run (which opens a window)
is left to run interactively via `npm run perf -- --spawn`.

Follow-up to the salvaged #56724: the runtime's _generate_xai_tts reads
voice_id, language, speed, auto_speech_tags, optimize_streaming_latency,
sample_rate, and bit_rate — but never text_normalization, and the xAI
/v1/tts payload builder has no such field. Surfacing it in the desktop
GUI would be a dead knob, so remove it from DEFAULT_CONFIG, constants.ts
(labels/descriptions/SECTIONS), and the ja/zh/zh-hant locale catalogs.
The other six xAI keys are all verified against tools/tts_tool.py.
Consistent naming across the xAI TTS settings section. Speed and
sampleRate are shown only when xAI is the selected provider, so they
get the prefix too.
The Settings > Voice provider dropdowns (tts.provider / stt.provider) only offer
the built-in providers plus whatever value is currently set. Custom `type: command`
providers declared in config.yaml aren't selectable — and once you switch away from
one it drops off the list, so you can only return to it by hand-editing config.
enumOptionsFor now merges in the names of any `type: command` entries under the
tts/stt config sections, so local command-backed engines appear alongside the
built-ins and can be switched freely from the UI.
Enumeration mirrors the runtime's own resolution so the dropdown can only offer a
name the runtime would actually honour: the canonical `<section>.providers.<name>`
location plus the back-compat top-level `<section>.<name>` block, the optional
`type:` discriminator, and the built-in-name guard. The guard compares against the
runtime's built-in sets rather than the ENUM_OPTIONS display list, which is not a
substitute — it already omits `deepinfra` (TTS) and `deepinfra`/`local_command`
(STT), so a `providers.deepinfra` command block would otherwise be offered as
selectable while the runtime dispatches to the native backend instead.
- helpers.ts: add commandProviderNames() + the built-in guard; merge for
tts.provider + stt.provider
- helpers.test.ts: cover both sections, incl. that non-command config blocks
aren't offered and that built-ins absent from the display list are never
offered as command providers
* fix(desktop): compute truthful per-provider readiness for Capabilities tool config
Backend: GET /api/tools/toolsets/{name}/config now sends a per-provider
'status' field ('ready' | 'needs_keys' | 'needs_auth' | 'needs_setup')
computed by the new provider_readiness_status() in tools_config:
- env vars declared: all set -> ready, else needs_keys
- Nous-managed rows: Portal login + per-category tool-gateway entitlement
(MANAGED_FEATURE_COVERAGE_CATEGORY) -> ready, else needs_auth
- post_setup 'xai_grok' rows: Grok OAuth or XAI_API_KEY -> ready, else
needs_auth
- other keyless post_setup rows: installed-state predicate
(_POST_SETUP_READY: kittentts/piper/ddgs/langfuse via find_spec,
agent_browser via _has_agent_browser, cua_driver via PATH probe);
unknown hooks fall back to is_active as the setup-completed signal
- genuinely-free keyless rows (Edge TTS) stay ready
Existing fields are untouched; 'status' is additive so older desktops
keep working.
* fix(desktop): render server readiness status in Capabilities provider pills
The panel's providerConfigured() heuristic pilled every zero-env-var
provider 'Ready' — including logged-out Nous Subscription rows, xAI TTS
without Grok OAuth, and never-installed KittenTTS/Piper. Render the
backend's per-provider 'status' instead:
- ready -> existing 'Ready' pill
- needs_auth -> warn pill 'Needs sign-in'
- needs_setup -> warn pill 'Needs setup'
- needs_keys -> no pill (env-var fields are the signal)
Keyed rows keep deriving ready/needs_keys from local envState so saving
or clearing a key updates the pill without a refetch. Older backends
without 'status' fall back to the legacy env-var heuristic (narrow
compat path, desktop/runtime update on separate clocks).
Adds the warn tone to the settings Pill primitive and needsSignIn /
needsSetup strings to all locale catalogs (en, zh, zh-hant, ja).
Two residual gaps in the #67369 salvage of #67214, found during review:
1. No timeout on the download client. Since #67369, mutable branch pins
hit the network on EVERY run, and the stale-cache fallback only fires
when download() returns Err. A black-holed connection (captive portal,
hung proxy, dropped packets) never errors, so the whole bootstrap hung
at resolve() instead of falling back to the cached script. Verified
live: a request to a non-routable address now errors at the 10s connect
timeout instead of hanging indefinitely.
2. The UTF-8 BOM was only written inside download(). Immutable commit-pin
caches take CachePlan::Reuse and are served untouched forever, and the
stale-fallback path also re-serves the old file - so a BOM-less .ps1
cached by a pre-fix installer kept reproducing the #67193 ANSI-codepage
parse failure on every retry (production builds pin BUILD_PIN_COMMIT,
so this is exactly the retry population). upgrade_cached_script() now
BOM-upgrades legacy .ps1 caches in place (atomic tmp+rename,
best-effort, idempotent) on both reuse paths; .sh untouched.
The salvaged helper cleared its line buffer on entry. Inside run_script's
tokio::select! loop, a stdout line arrival cancels the in-flight stderr
read (and vice versa); read_until had already consumed bytes into the
buffer, and the next call's clear() silently dropped that partial line.
Keep partially-read bytes across cancellation (clear only after a full
line is decoded) and emit an unterminated final line at EOF instead of
swallowing it. Adds a cancellation regression test (fails against the
clear-on-entry version) and an EOF-tail test.
Locks the #67193 invariants: localized PowerShell error bytes survive
decode_console_bytes / read_decoded_line (including CP1252-only 0x91/0x92
punctuation), cached .ps1 files get a single UTF-8 BOM for Windows
PowerShell 5.1 -File, .sh stays BOM-less, and mutable branch caches plan
a refresh with stale-cache fallback.
Windows PowerShell 5.1 emits ParserError text in the console ANSI code page,
but the GUI bootstrap aborted BufReader::lines() on the first non-UTF-8 byte
and Retry kept reusing a poisoned install-main.ps1 for branch pins. Decode
child output with a real Windows-1252 fallback, write a UTF-8 BOM on cached
.ps1 files for -File, and refresh mutable branch/tag caches on each run
(immutable SHAs stay cached).
Fixes#67193
Route session color through one computed store ($sessionColorById) that
both the sidebar rows and the pane tabs read, so a session and its tab can
never show different colors. Recomputed only when the session list or
projects change (cold atoms — the streaming pulse lives elsewhere) and read
as an O(1) lookup, never re-derived per render.
Tabs previously had no color at all: the strip renders only a title string.
Add a generic `accent` to the pane contribution that the tab strip paints as
a lead dot; the session tiles (via paneMirror) and the main workspace tab
(syncWorkspaceTitle) feed it from the same shared map. Precedence now lives
in one place, ready for per-session override / agent-set color (#66565).
