The desktop window opened at a hardcoded 1220×800 every launch, discarding
whatever size and position the user left it at (#39101) — on macOS the dock
reopen was the most visible case, but every restart reset it.
A small window-state.json under userData (same pattern as connection.json /
updates.json) records the window's normal bounds plus its maximized flag,
written debounced on resize/move/maximize and flushed on close, applied on the
next createWindow(). getNormalBounds() captures the pre-maximize size so an
un-maximize next session lands where the user actually sized it.
Restore is defensive: sanitize rejects garbage, drops off-screen positions
(window falls back to Electron centering), and caps a size saved on a
since-disconnected larger monitor to the largest current display. The geometry
math lives in a side-effect-free window-state.cjs so it unit-tests with
node --test, no Electron boot. No new dependency.
Salvages #39154 by @jeffrobodie-glitch — same userData approach and validation
intent, reimplemented tighter and folded into one module.

Windows toast notifications silently no-op unless the app sets an
AppUserModelID — new Notification().show() returns without error and
nothing appears. The desktop's native-notification system (approval,
turn-done, input, etc.) was therefore dead on Windows while working on
macOS/Linux.
Set the AUMID to the build appId (com.nousresearch.hermes) on Windows
right after app.setName, so toasts route to the installed Start Menu
shortcut. No-op on macOS/Linux, which don't require it.
On a Linux source install the in-app updater ran the full backend update +
desktop rebuild successfully but never restarted the app — it hung forever on
the applying overlay with no close button. Two causes:
- applyUpdatesPosixInApp() only handled the macOS .app bundle swap;
runningAppBundle() is null off macOS, so Linux fell through to
{ ok: true, backendUpdated: true } without ever relaunching.
- The renderer store had no terminal state for that result shape, so
$updateApply stayed { applying: true } and the overlay's close button
(hidden while applying) never appeared.
Fix (new electron/update-relaunch.cjs, pure + unit-tested):
- Decide the Linux outcome from whether the *running* binary is the one we
just rebuilt (execPath under release/<plat>-unpacked, path-segment-aware so
linux-unpacked-evil can't masquerade) and whether its chrome-sandbox helper
is launchable (root:root + setuid, or an --no-sandbox / ELECTRON_DISABLE_SANDBOX
opt-out):
relaunch — detached watcher waits for this PID to exit (graceful, then
SIGKILL), self-deletes, and re-execs the rebuilt binary with the original
launch context (filtered args + HERMES_*/sandbox env + cwd) restored.
guiSkew — AppImage/.deb/.rpm/dev: backend updated but this GUI package was
NOT changed; surface an honest closeable 'reinstall the desktop app'
terminal state instead of lying that it loads next launch (#37541 skew).
manual — rebuilt binary but sandbox helper not launchable: keep the
working window, don't quit into a dead app.
- store/updates.ts lands a terminal, closeable state for EVERY resolved apply
outcome (handedOff / guiSkew / manualRestart / updated-not-relaunched / error)
so the hang is impossible regardless of platform or result.
- New DesktopUpdateStage values (update/rebuild/done/guiSkew) + GuiSkewView so
progress reads correctly and the skew state is closeable. i18n in all four
locales (en/ja/zh/zh-hant) in parity.
- electron/update-relaunch.test.cjs (16 tests) + store outcome tests.
Salvaged from #45205 onto current main. Linux quit dwell uses the shared
UPDATE_HANDOFF_DWELL_MS (2.5s) from #50448 for consistency. Four-locale i18n
parity, AUTHOR_MAP entry, and the test wiring added on top.
Closes#45205.
Follow-up to #50238/#50381. The restart-loop is now SAFE (marker + launch
gate), but the trigger that lured users into relaunching mid-update remained:
on the in-app update hand-off the desktop window vanished almost immediately
(app.quit() 600ms after spawning the detached updater), before the updater's
own window appeared — a blank-screen gap that looks like a crash.
- Linger on the update overlay for UPDATE_HANDOFF_DWELL_MS (2.5s, was 600ms)
before quitting, on BOTH hand-off paths (in-app update + Windows bootstrap
recovery), so the message lands and bridges to the updater window.
- Strengthen the restart-stage copy and the overlay's applyingBody/applyingClose
to explicitly tell the user the window will reopen automatically and NOT to
reopen Hermes themselves while it updates. All four locales (en/ja/zh/zh-hant)
updated in parity.
Pure UX; does not touch the #50381 marker/gate mutual-exclusion safety net.
When a Windows user relaunches Hermes while an in-app update is still
running (the desktop vanished with no progress and looks crashed), the
fresh instance spawns its own dashboard backend. That backend re-locks
the venv shim, the updater's straggler cleanup (force_kill_other_hermes
-> taskkill /F /T /IM hermes.exe) kills it, the launch dies with the 45s
"backend didn't come up" timeout, and the user relaunches into the same
trap -- an infinite respawn/kill loop (#50238).
Root cause: no mutual exclusion between an applying update and a fresh
desktop spawning its own local backend.
Fix: the updater publishes a HERMES_HOME/.hermes-update-in-progress
marker (pid + start time) for the whole run via an RAII drop-guard that
removes it on every exit path (success, early return, panic). A
freshly-launched desktop checks the marker before spawning its local
backend and PARKS until the update finishes -- then brings the backend
up itself (it is the surviving instance; the updater's own relaunch hits
the single-instance lock and quits). A stale marker (dead pid or past a
20-minute ceiling) is pruned so a crashed updater can never strand
future launches. No rogue backend spawns mid-update, so
force_kill_other_hermes has nothing legitimate to kill.
Marker parse/staleness logic is extracted to update-marker.cjs and
unit-tested; the Rust guard has unit tests; the Rust-write <-> JS-read
contract is E2E-verified.
The port-announcement clock in waitForDashboardPort starts the instant the
backend process is spawned — before uvicorn binds its socket. On a cold
install the child first compiles and imports the whole hermes_cli.main ->
web_server -> FastAPI/uvicorn chain, and on Windows real-time AV scans every
freshly written .pyc. That pre-bind cost can exceed the old hardcoded 45s
deadline, so the desktop killed a healthy-but-still-starting backend and
respawned it, piling up orphaned processes (#50209).
Raise the default to 90s and make it overridable via
HERMES_DESKTOP_PORT_ANNOUNCE_TIMEOUT_MS, clamped to a 45s floor so a bad
override can't reintroduce the loop. Warm starts still announce in well under
a second; both call sites inherit the new default with no change. Adds
backend-ready.test.cjs (wired into test:desktop:platforms).
Add the in-window floating pet (sprite, speech bubble, contact shadow,
profile-scoped, resize-safe) and a pop-out always-on-top overlay window
with gestures and notifications. Add the Cmd+K pet picker page plus the
appearance gallery and size slider in settings. Includes the pet stores,
electron overlay wiring, i18n strings, and store tests.
Verify createLinkTitleWindow mutes audio (regression guard for #49505) and
keeps the hardened offscreen defaults, and register the new test file in the
desktop platforms test script.
Tier-2 link-title resolution loads the URL in an offscreen BrowserWindow to
read its <title> when curl can't. That window was never muted, so pages that
autoplay media (e.g. YouTube `watch` URLs) leaked ~2s of audio every time a
session containing such links was re-rendered. Move the window creation into a
dedicated helper that calls `webContents.setAudioMuted(true)` immediately after
construction, so the offscreen probe can never emit sound.
Fixes#49505
Remote displays (RDP/SSH/X11) silently disable GPU hardware acceleration with
only a console.log, leaving the user unaware that software rendering is
active. Expose the detected reason over IPC and surface a dismissible banner
in the renderer.
Behavior-preserving cleanups on the managed-node resolver:
- Hoist _candidate_node_command_names() out of the inner dir loop in
find_hermes_node_executable (computed once, not per directory).
- Drop redundant os.environ.copy() at the two with_hermes_node_path(
os.environ.copy()) sites \u2014 the helper already copies os.environ when
called with no argument (verified env-equivalent).
- Add reciprocal keep-in-sync comments between iter_hermes_node_dirs()
(hermes_constants.py) and hermesManagedNodePathEntries() (electron
main.cjs), which mirror the same platform-ordering rule across the
Python/Node boundary.
The `before-quit` handler tears down the bootstrap controller, preview
watchers, and the Python backend but never disposes live PTY sessions.
When `app.quit()` proceeds to `FreeEnvironment()`, node-pty's
`ThreadSafeFunction::CallJS` callback fires on a half-torn-down
environment, throws a C++ exception that can no longer be caught, and
the process aborts (microsoft/node-pty#904).
Iterate `terminalSessions` and call `disposeTerminalSession()` (which
already calls `pty.kill()` + deletes the map entry) before killing the
backend, so the ThreadSafeFunctions are removed before teardown begins.
Closes#48335
The desktop self-update runs `hermes update` then `hermes desktop
--build-only`, and only relaunches if the rebuild returns 0. The first
`--build-only` can exit nonzero on a still-settling post-update tree or a
network-blocked Electron fetch that the installer's self-heal repaired
mid-run — so both updaters (the Tauri setup binary and the in-app POSIX
path) bailed before the relaunch step. The update landed but the app
never restarted; a manual launch worked because the heal had completed.
Retry `--build-only` once in both paths before failing, mirroring the
retry-once `hermes update` already does (and the CLI `hermes update`'s
own desktop rebuild). A second run builds clean off the healed dist and
is a near-no-op when the first actually succeeded (content-hash stamp).
- update.rs: retry stage 2; add rebuild_needs_retry() + test
- main.cjs: retry via new update-rebuild.cjs helper (behavior-tested)
* fix(desktop): keep streaming painting in unfocused secondary chat windows
The chat transcript streams to screen through a requestAnimationFrame-gated
flush, which Chromium pauses for blurred/occluded windows. The primary window
opted out with `backgroundThrottling: false`, but the secondary "session
windows" (cmd-click pop-out, new-session, subagent-watch) hand-copied their
webPreferences and silently lost that flag — so a streamed answer in one of them
stalled until the window regained focus (reported on Windows 11). The primary
window's own comment even claimed it was "matching the secondary windows," which
was no longer true.
Hoist the chat-window webPreferences into a single shared factory
(`chatWindowWebPreferences`) in session-windows.cjs and use it for BOTH windows,
so they can never drift on this flag again.
* test(desktop): assert chat windows disable background throttling
Cover chatWindowWebPreferences: it must set backgroundThrottling=false (so the
streaming transcript paints while the window is blurred) and pass the preload
path through while keeping the hardened defaults (contextIsolation, sandbox,
nodeIntegration=false).
A GUI app launched from Explorer inherits the environment block captured at
login, so a HERMES_HOME set via 'setx' AFTER login is invisible in process.env
even though the CLI (a fresh shell) sees it. The desktop then silently fell
back to %LOCALAPPDATA%\hermes and reported 'No inference provider configured'
despite a valid configured home (#45471).
resolveHermesHome() now consults the live HKCU\Environment registry value on
Windows before the LOCALAPPDATA default. New windows-user-env.cjs helper parses
'reg query' output, expands %VAR% refs, and fails safe (returns null off-Windows,
on spawn error, or empty value). The registry value is normalized through the
same normalizeHermesHomeRoot() path as the env var for consistency.

Adds a native OS notification system (Electron Notification, routed cross-OS)
distinct from the in-app toast feed. Before this, one hardcoded cue existed
(message.complete while document.hidden) with no settings or event coverage.
- Engine (store/native-notifications.ts): localStorage-backed prefs (master
switch + per-kind toggles) and a gated dispatcher over five kinds — approval,
input, turnDone, turnError, backgroundDone — with a 1s per-(kind,session)
self-evicting throttle.
- Gating: "backgrounded" = document.hidden OR !document.hasFocus(), so an
alt-tabbed window still counts as away. Completion kinds fire only when
backgrounded and for the active session (no spam from a busy gateway);
attention kinds (approval/input) also break through for off-screen sessions.
- Wired into real event sites (use-message-stream.ts): message.complete, error,
approval/clarify/sudo/secret.request; backgroundDone from composer-status at
the running -> exited transition.
- Click focuses the window and jumps to the originating session; approval
notifications carry Approve/Reject buttons that resolve in place over
approval.respond, mirroring the in-app Run/Reject bar.
- Settings: new Notifications panel (master + per-kind switches, test button
with real OS-result feedback). Full i18n (en/ja/zh/zh-hant).
Group recents as parent-repo → worktree → sessions using local git
metadata (probed over IPC, with a path-name heuristic fallback for
remote backends). Single-worktree repos collapse to one level. Sessions
order by creation time and never reshuffle on new messages.
Also: fuse the status stack to the composer border, restore icon actions
in the queue panel, fix sidebar label truncation and drag styling, hide
sticky-message attachments while pinned, and bump the terminal font.
Replace the PortPool-based port reservation system (9120-9199 range) with OS-assigned ephemeral ports via --port 0.
Before: Desktop probed a hardcoded port range, reserved ports in-process to close TOCTOU races, and passed the chosen port to the dashboard via CLI arg.
After: Desktop spawns dashboard with --port 0, parses the actual port from a stdout announcement line (HERMES_DASHBOARD_READY port=<N>), and uses that for WebSocket connections.
Changes:
- web_server.py: add --port 0 support with SO_REUSEADDR pre-bind + announcement; add EADDRINUSE preflight for explicit ports
- main.cjs: remove PortPool, PORT_FLOOR/CEILING, pickPort(), isPortAvailable(); add waitForDashboardPort() stdout parser
- Delete port-pool.cjs and port-pool.test.cjs (106 lines removed)
Net effect: eliminates the entire TOCTOU-mitigation reservation infrastructure and arbitrary port range constraints. OS handles port allocation natively.
A see-through-window control (0–100, off by default) that maps to the
native window opacity via setOpacity — the desktop shows through the whole
window, the same effect as the Windows shift-scroll trick. macOS + Windows;
a no-op on Linux (no runtime window opacity).
Renderer owns the value (persisted, nanostore) and mirrors it to the main
process over IPC; main persists it to translucency.json so a cold launch
applies it at window creation before the renderer reports in.
* feat(desktop): session-scoped status stack + kill new-window theme flash
Stack subagents, background tasks, and the queue into one collapsible
"sink" above the composer, reusing the queue's chrome so every status
reads as one piece. Extracts shared StatusSection / StatusRow /
TerminalOutput primitives and a unified $statusItemsBySession store
(subagents mirrored, background owned here, merged + grouped for render).
Renames BrailleSpinner → GlyphSpinner now that it drives more than braille.
Separately, fix the white flash on every new/cmd-clicked window: macOS
`vibrancy` paints an NSVisualEffectView that follows the OS appearance and
ignores `backgroundColor`, so a dark app on a light-mode Mac flashed white
until the renderer painted over it. Pin `nativeTheme.themeSource` to the
app theme (persisted to userData so cold launches paint right before the
renderer loads), hold windows with `show:false` until `ready-to-show`, and
pre-paint the themed background via an inline script before the bundle runs.
* feat(desktop): dock the slash popover to the composer via one shared fill var
The slash·@ popover (and ? help) now docks onto the composer's edge with the
same chrome as the queue/status stack — rounded outer corners, fused borderless
edge, no shadow — but keeps its own narrow width.
Surface + drawer paint a single --composer-fill var; the state ladder
(rest / scrolled / focused / drawer-open) lives once in styles.css on
[data-slot='composer-root']. The :has() drawer-open rule is last and forces an
opaque fill, since translucent glass sampling different backdrops (thread vs
fade gradient) can never match. This replaces the focus-within !important
override that repainted the surface behind every previous matching attempt.
Also drop the chevron column from the project file tree — the folder open/closed
icon already carries the expand state.
* feat(desktop): base inset for file tree rows (post-chevron alignment)
* feat(desktop): wire the status stack's background tasks to the real process registry
The background group was UI-only (dev-mock seeded). Now it's live e2e:
- tui_gateway: new session-scoped `process.list` (registry snapshot filtered
by the session's session_key, plus a 4KB output tail for the inline
terminal viewer) and `process.kill` (single process, ownership-checked —
unlike process.stop's kill_all).
- Renderer: `reconcileBackgroundProcesses` syncs snapshots into the store
layout-stably — rows keep their position when state flips (never re-sort),
new processes append, unchanged rows keep object identity so memoised rows
skip re-rendering, and a dismissed-set stops the registry's retained
finished procs from resurrecting X-ed rows.
- Refresh triggers: session open, terminal/process tool.complete,
status.update(kind=process) from the gateway's notification poller, and a
5s poll armed only while a running row is visible (catches silent exits).
- Stop = real `process.kill` + optimistic dismiss; Dismiss = client-side
with resurrection guard.
- Re-keyed the stack to the RUNTIME session id: it was keyed by the stored
session id, where neither subagent events nor process.list would ever land.
- Deleted dev-status-mocks.ts (__hermesStatusMocks) — no more seed shit.
Reconcile invariants covered in store/composer-status.test.ts.
* feat(desktop): todos + openable subagents in the status stack, self-healing file tree
- todo lists move out of the inline chat panel into the composer status stack
(checklist icon, dashed ring = pending, spinner = in progress, check = done),
fed live from todo tool events and seeded from history on session open
- subagent rows carry the child's real session id end-to-end
(delegate_tool → gateway → renderer) so clicking one opens ITS session window
- status stack publishes its measured height so the thread's bottom clearance
grows with it; card paints the shared --composer-fill so focused/scrolled
states match the composer exactly
- file tree self-heals: ENOENT roots retry on a 3s cadence + Try again button,
and the main process expands ~ in IPC paths (gateway cwds arrive as ~/...)
- composer drag-drop of tree entries inserts inline refs instead of attachments
* fix(desktop): file tree falls back to the workspace dir when a session's cwd is gone
Sessions record their launch cwd; deleted worktrees leave that path dead,
so opening such a session swapped the tree from the default workspace to a
directory that ENOENTs forever — the 3s retry just spun on it. On a root
read error the tree now asks main to sanitize the cwd (prefers the
configured default project dir), displays that fallback, and quietly
re-probes the original path so it switches back if the dir reappears.
* feat(desktop): working restore-checkpoint button on past user prompts
The discard icon on hover of a past user bubble was decorative — clicking
did nothing. It's now a real control: a confirmation dialog explains that
everything after the prompt is removed, then the session rewinds to that
turn and reruns the same prompt (prompt.submit with
truncate_before_user_ordinal, the same mechanism the edit composer uses).
Failures rethrow into the dialog's inline error instead of toasting.
* fix(desktop): show the restore-checkpoint button on the latest user prompt too
Restoring the most recent prompt is just 'retry this turn' — no reason to
exclude it. Stop still takes the slot while the turn is running.
* fix(desktop): finished todo lists clear themselves out of the status stack
A list whose every item is completed/cancelled lingers ~4s so the final
checkmark is visible, then the todo group drops out of the stack. A fresh
active list arriving within the linger cancels the scheduled clear.
* chore(desktop): drop dead editableCheckpoint copy, terser restore confirm
* fix(desktop): rewind clears the abandoned timeline's todos + background
Restoring to (or editing) an earlier prompt rewinds the conversation, but
the todos and background processes spawned by the now-discarded turns kept
showing in the status stack — and the real background processes kept
running. Both rewind paths now clear the session's todo rows and kill +
drop its background processes before the fresh run repopulates them. Also
drops the click-to-edit clamp transition, which flashed a half-expanded
bubble on the way into the edit composer.
* feat(desktop): user messages are always editable; edit/restore revert mid-stream
The bubble is now always click-to-edit — even while a turn streams — instead
of going inert during a run. Sending an edit acts like restore: it rewinds to
that prompt and re-runs with the new text. Both edit and restore can fire
mid-stream now; the gateway refuses prompt.submit while a turn runs (4009
"session busy"), so they interrupt the live turn first and retry the submit
until the cooperative interrupt winds it down. Restore (re-run as-is) shows on
every prompt except the latest running one, which keeps the Stop button.
* fix(desktop): label preview-pane ⌘L selections with the filename, not "zsh"
The terminal owns a global ⌘/Ctrl+L "send selection to composer" shortcut, so
selecting text in the file preview pane and hitting it fell through to the
terminal handler — which imported the right text but labelled the composer ref
"zsh:N lines" off the shell name. When the selection isn't an xterm selection,
label it with the previewed file instead.
* fix(desktop): ⌘L on a preview line selection inserts the @line ref, like dragging
The source preview lets you select lines in the gutter and drag them into the
composer as an @line:path:start-end ref. ⌘/Ctrl+L now does the same when a line
selection is active — it drops the identical ref instead of falling through to
the terminal's global handler (which grabbed the native text selection and sent
a bogus terminal block). Capture-phase + stopPropagation so it wins; with a line
selection there's no native selection, so the terminal handler stays out of it.
* chore: gitignore apps/desktop/demo/ scratch output
The desktop demo prompt writes demo/*.txt during recorded walkthroughs; it's
throwaway, never part of the app. Ignore it so it stops cluttering git status.
* feat(desktop): subagent watch windows, hard stop, sidebar hygiene
Child-session mirror for live subagent windows, delegate sessions tagged
and excluded from the sidebar, composer focus/stop polish, and WS stall
resilience on the gateway transport.
* refactor: DRY delegate SQL + trim status-stack noise
Extract shared listable-child and delegate-delete helpers in hermes_state,
collapse cancelRun busy release, and cut comment bloat in resume/status paths.
* fix(desktop): hide orphaned subagent sessions in sidebar
Cascade-delete all ephemeral children on parent delete (not just tagged rows),
run v16 backfill to tag legacy orphans, and record new delegates as source=subagent.
* fix: restore orphan contract for untagged children + lazy session eviction
Cascade-delete only _delegate_from-tagged rows (v16 backfill covers legacy),
walk marker chains recursively with FK-safe orphaning, gate lazy watch
sessions out of the still-starting eviction exemption via an explicit flag,
pass session_id to _make_agent only when resuming, and hide source=subagent
from session search.
* fix(gateway): gate child mirror off upgraded sessions + age out stale run entries
Review findings: the mirror could interleave synthetic events with a real
native stream once a watch window upgrades (prompt.submit builds an agent),
and a lost subagent.complete left _active_child_runs pinning running=true
forever. Mirror now stops when the live session owns an agent; liveness
reads ignore entries older than an hour.
* fix(gateway): reject prompt.submit into a watch session while its child runs
A lazy watch session's running flag is False (the run lives in the parent
turn), so typing mid-run sailed past the busy guard and built a second agent
racing the in-flight child on the same stored session. Busy error until the
run completes; afterwards the submit upgrades into a normal conversation.
* refactor(gateway): DRY watch-resume payload + compose listable-child SQL
Fold the duplicated child-run busy overlay into one _reuse_live_payload
helper across both resume reuse paths, collapse the twin mirror early-returns,
and build _LISTABLE_CHILD_SQL from _BRANCH_CHILD_SQL instead of restating it.
* fix(desktop): clip horizontal overflow on sidebar scroll areas
Add overflow-x-hidden alongside overflow-y-auto on session list scrollers
and the shared SidebarContent primitive — vertical scroll unchanged.
macOS Desktop backend processes can still miss Apple Silicon Homebrew paths even after adding Hermes-managed Node and venv bins. That leaves `/codex-runtime on` unable to find a Homebrew-installed `codex` binary at `/opt/homebrew/bin/codex`.
Add a small testable backend env helper that builds the dashboard subprocess environment in one place. It prepends Hermes-managed Node and venv bins, appends missing POSIX sane PATH entries individually, preserves caller precedence without duplicates, and keeps Windows PATH casing/delimiters intact.
Wire both source-checkout and active-install backend descriptors through the helper, and add Node regression coverage to the desktop platform test suite.
- Add ELECTRON_SKIP_BINARY_DOWNLOAD=1 to nix/lib.nix to prevent offline download failures.
- Manually trigger native compilation of node-pty via npm rebuild --build-from-source in buildPhase.
- Run stage-native-deps.cjs to copy the natively compiled binary into build/native-deps.
- Flatten native-deps and install-stamp.json to the root of the output derivation in installPhase, matching electron-builder's extraResources behavior so main.cjs can find it at process.resourcesPath + '/native-deps/node-pty'.
- Add doCheck=true and a strict checkPhase to fail fast if the staged native binary is missing.
Node >=18 / Electron 40 ship fetch; the hand-rolled http/https.request
plumbing buys nothing. AbortSignal.timeout replaces the socket timeout,
protocol guard and >=400 rejection semantics preserved. 13/13 unit
tests and the live web_server.py repro both green over the new
transport.
Both spawn paths (startHermes, spawnPoolBackend) duplicated the same
resolve -> log-fallback -> foreign-check -> throw dance. Collapse it into
adoptServedDashboardToken(baseUrl, spawnToken, {childAlive, label}) in
dashboard-token.cjs; childAlive is a thunk so liveness is sampled after
the fetch. Drop the redundant backendPool.delete in the pool's throw
path (the child exit/error handlers already own pool eviction).
Validated end-to-end against a real web_server.py backend, not just
units: token-injection regex vs the actual served index.html, foreign
refusal (dead child + live squatter), benign drift adoption, and the
401-vs-200 token auth split on /api/sessions.
Two fixes to the Electron desktop launch path, with the port-reservation logic extracted into a unit-tested module:
1. hermes:bootstrap:reset ("Reload and retry") only cleared connectionPromise, leaving the live backend alive; the orphan kept binding PORT_FLOOR (9120) so the next startHermes() hit EADDRINUSE / "Object has been destroyed" and the window looped. Await teardownPrimaryBackendAndWait() so the reset stops the old backend before restarting.
2. pickPort() probes-then-closes a socket before the real bind happens in a separate Python child, so two concurrent spawns (primary + pool backend) could both be handed PORT_FLOOR and one died with EADDRINUSE. The reservation bookkeeping is extracted into electron/port-pool.cjs (PortPool): pickPort() reserves the chosen port until the child exits and releases it on every exit/error/throw-before-spawn path, closing the TOCTOU window.
PortPool is dependency-injected (probe passed in) and socket-free, unit-tested in electron/port-pool.test.cjs (8 cases) and wired into the test:desktop:platforms script.
(cherry picked from commit d4133945b9)
The served-token fallback adopts whatever token the dashboard HTML
injects. That is correct when our own child regenerated the token (env
pin lost across a shell-wrapped spawn), but wrong when the readiness
probe answered from a process we did not spawn: /api/status is public,
so an orphaned dashboard squatting the port passes waitForHermes while
our child dies on the bind conflict. Silently adopting that process's
token would authenticate the renderer against a foreign backend,
possibly on the wrong profile.
Discriminate on child liveness: the desktop pins
HERMES_DASHBOARD_SESSION_TOKEN on every spawn, so a live child always
serves our token. Served-token mismatch + dead child = foreign backend;
fail the boot loudly instead of connecting. Mismatch + live child keeps
the adopt-served-token salvage from #43720.
A 'recipe' is a one-place definition of an automation that every surface
renders natively. The slot schema (cron/recipe_catalog.py) is the single
source of truth; four renderers consume it, and all paths end at the same
cron.jobs.create_job — no second job engine.
Form where there's a screen, conversation where there's a chat line:
- Dashboard / GUI app: a Recipes sub-tab on the Cron page renders each
recipe's typed slots as a form (time-picker, enum dropdown, free-text);
submit POSTs /api/cron/recipes/instantiate which fills + creates the job.
- CLI / TUI / messengers: /cron-recipe lists the catalog, shows a recipe's
fields, or fills + creates from a pasted 'key slot=val' command. The shared
handler (hermes_cli/cron_recipe_cmd.py) names any missing/invalid slot so
the agent can ask a targeted follow-up.
- Docs: a generated Cron Recipes catalog page (website, .mdx + React cards)
shows each recipe with a copy-paste command and a 'Send to App' button.
- Desktop: a hermes:// URL scheme (Electron single-instance lock +
setAsDefaultProtocolClient + open-url/second-instance) routes
hermes://cron-recipe/<key>?slot=val into the chat composer pre-filled.
Typed slots (time/enum/text/weekdays) with defaults: users never type raw
cron — recipes parameterize time-of-day and weekday sets and translate to
cron expressions; a free-text 'schedule' slot is the full-flexibility escape
hatch. Consent-first throughout: nothing schedules without an explicit submit
or send.
Core:

* fix(desktop): Harden local file tree paths
Normalize Electron local path handling across file tree, preview, media, and git-root flows. Reject malformed and Windows device paths, recheck sensitive files after realpath resolution, and preserve external symlink traversal with stable renderer errors.
* fix(desktop): Address file tree review feedback
Extract the remote-detection helpers (canonicalGitHubRemote, isSshRemote,
isOfficialSshRemote) from main.cjs into a testable update-remote.cjs sibling
module and add a node:test suite, wired into test:desktop:platforms.
main.cjs requires('electron') at load, so its inline helpers weren't unit
testable. The Python side of #43754 shipped a regression test; this gives the
desktop side the same coverage for the security-critical detection that keeps
passive update checks off the SSH origin (avoiding FIDO2/passkey touch
prompts). Tests assert SSH/HTTPS forms canonicalize equal, official SSH is
detected case-insensitively, and forks / other hosts / the HTTPS remote are
NOT misclassified.
* fix(desktop): honor default project directory for new sessions
The Settings picker persisted project-dir.json but the renderer kept
seeding new chats from sticky localStorage home. Prefer the configured
default on boot and session.create, pin TERMINAL_CWD at backend spawn,
and reject packaged install-dir paths that regressed after #37536.

* fix(desktop): address review on default project dir PR
Add workspace cwd precedence tests, extract isPackagedInstallPath for
platform test coverage, and stop rewriting live $currentCwd when a
session is already active (cache-only until the next new chat).

* refactor(desktop): dock terminal under chat and simplify file rail
Keep the right rail focused on file browsing while moving the persistent terminal into the chat column bottom slot, and make terminal colors follow the active light/dark mode instead of a fixed Solarized palette.
* fix(desktop): make the terminal a resizable, themed side pane
- Move the terminal into a resizable pane (viewport-% widths) that shares
<main>'s stacking context, so its drag handle no longer sits under the
fixed terminal overlay; works on either rail side.
- Restore +x on node-pty's spawn-helper before the first spawn to fix
"posix_spawnp failed" on macOS prebuilds (real cause; drop the redundant
shell-candidate retry loop).
- Gate terminal open/fit/start on document.fonts.ready and strip leading
blank rows (re-armed before the resize Ctrl-L redraw) so the prompt sits
flush at the top with no starship add_newline gap.
- Inherit the app editor-surface color as the terminal background.
- Bind Ctrl+` (⌃` on macOS) to toggle the terminal; add a palette entry.
* feat(desktop): show platform hotkey hints in the command palette
- Render each palette item's live binding as a <KbdGroup> hint via a new
comboTokens() helper (mac shows ⌘/⌃/⌥/⇧, every other platform shows
Ctrl/Alt/Shift — never a ⌘ on PC).
- Default the terminal toggle to ⌘` / Ctrl+` (the ~ key) on both platforms.
- Drop the hardcoded (⌘⏎) baked into the composer steer tooltip; render it
platform-aware with formatCombo instead.
* fix(desktop): drop the active check on the command-palette terminal item
* fix(desktop): remove active/check states from the command palette
* fix(desktop): allow ⌥/Shift-drag selection over mouse-mode TUIs
Full-screen apps (hermes --tui, vim) enable mouse reporting, so a plain
drag can't select text and ⌘/Ctrl+L (add-selection-to-chat) had nothing
to send. Enable macOptionClickForcesSelection so ⌥-drag on macOS (Shift
elsewhere) forces a native selection over mouse-mode apps.
* feat(desktop): tell the in-pane agent it's embedded in the GUI
Set HERMES_DESKTOP_TERMINAL=1 on the terminal pane's shell env and surface
it in build_environment_hints, so a hermes/--tui launched inside the pane
knows it's next to the GUI chat and that ⌥/Shift-drag + ⌘/Ctrl+L sends a
selection to the composer. Distinct from HERMES_DESKTOP (agent backend).
* refactor(desktop): drop the redundant Ctrl+` terminal-toggle fallback
The toggle now ships as mod+` on both platforms, so the standard combo
index handles it — the bespoke fallback (and its stale 'old default'
comment) is dead weight.
* fix(desktop): read live terminal selection for ⌘/Ctrl+L
A redraw-heavy TUI (spinners/clocks) outruns onSelectionChange, leaving the
React selection state empty so the state-gated shortcut listener never
attached and ⌘L no-op'd. Always listen and read xterm's live selection (with
a native fallback) at press time; only swallow the key when there's text to
send. Drops the now-redundant custom key handler.
* feat(desktop): make any agent aware it's in the Hermes desktop GUI
Generalize the runtime-surface hint: fire for HERMES_DESKTOP (the backend
powering the GUI chat) as well as HERMES_DESKTOP_TERMINAL (a hermes in the
embedded terminal pane), so it's about being inside the desktop GUI, not
about being a TUI. The terminal-pane selection note stays pane-specific.
* feat(desktop): give the GUI agent a read_terminal tool
The in-app terminal buffer lives in the renderer (xterm), so expose it to the
chat agent over the same blocking bridge clarify uses: read_terminal emits
terminal.read.request, the renderer serializes the buffer (visible screen by
default, or a start_line/count range against total_lines) and answers
terminal.read.respond. Gated to the GUI via HERMES_DESKTOP.
Also restores the flipped-layout titlebar inset fix (app-shell +
desktop-controller) for terminal/preview rails at the window's left edge.
* chore(desktop): trim read_terminal comments
* feat(desktop): add a terminal toggle to the statusbar
The file rail lost its terminal icon, leaving ⌘` and the command palette
as the only ways in. Add a one-click toggle to the statusbar's left
cluster, mirroring the command-center item: it reads $terminalTakeover so
it lights up while the pane is open and stays in sync with the hotkey, and
is gated to chat view (the only place the pane can show).
* fix(desktop): relabel the terminal header button to what it does
The in-pane button claimed a focus/split fullscreen toggle ("Focus
terminal view" / "Return to split view", screen-full/normal icons), but
the terminal is just a resizable side pane — there's no fullscreen. The
button only mounts while the pane is open, so the focus branch was dead
and clicking it merely closed the terminal. Relabel to "Hide terminal"
with a close icon, drop the dead conditional and the now-unused takeover
read.
* fix(desktop): move the terminal toggle next to the version item
Relocate it from the left cluster to the right of the statusbar, just
left of the client version item.
* feat(desktop): default the terminal to PowerShell on Windows
Prefer pwsh (7+) then Windows PowerShell 5.1 over cmd.exe, falling back to
comspec only when neither is present. -NoLogo drops the startup banner so
the prompt sits flush like the POSIX shells.
* feat(desktop): show a persistent divider on the terminal pane
The resize sash only painted on hover, so the terminal/chat boundary was
invisible at rest. Add an opt-in `divider` prop to Pane that paints a thin
resting hairline on the resize edge (side-aware, so it tracks the rail when
the layout flips) and enable it on the terminal pane.
* refactor(desktop): resolve the terminal shell instead of hardcoding it
Make shell selection a real resolver: an explicit override wins
(HERMES_DESKTOP_SHELL on both platforms, $SHELL on POSIX), otherwise
auto-detect the best installed shell — pwsh > Windows PowerShell 5.1 > cmd
on Windows, zsh > bash > sh on POSIX. A shared shellSpecFor() picks the
interactive flags by family, so an overridden bash/pwsh/cmd all launch
correctly.
* fix(desktop): repaint the terminal on light/dark switch
Setting term.options.theme updated colors for the DOM renderer but not the
WebGL one, which caches glyph colors in a texture atlas — so already-drawn
cells kept their old palette after a mode switch. Hold the WebglAddon in a
ref and clear its atlas when the theme changes.
* fix(desktop): match the terminal palette to VS Code Light+/Dark+
Adopt VS Code's exact default ANSI palette (the terminalColorRegistry
defaults), enable minimumContrastRatio: 4.5 so foregrounds are clamped
against the background the way the integrated terminal does, and key the
light/dark choice off renderedMode (the painted surface) instead of
resolvedMode so it can't invert. The canvas + inset paint the live skin
surface (--ui-editor-surface-background) so the terminal blends with the
app and follows light/dark, while the contrast clamp keeps colors crisp.
* fix(desktop): tighten command palette search to substring matching
cmdk's default fuzzy scorer matched anything with the query letters
scattered across an item, so e.g. "color" never narrowed to color
entries. Add a substring filter: every typed word must literally appear
in an item's value/keywords, keeping results tight and predictable.
* fix(desktop): blend the terminal header into the skin surface
The persistent-terminal overlay painted the static palette background
(#1e1e1e/#ffffff), so the transparent header strip revealed a near-black
slab above the surface-colored body. Paint the overlay with the live
--ui-editor-surface-background so header and body read as one pane.
* fix(desktop): re-resolve the terminal surface on skin switch
The canvas surface only re-resolved on light/dark change, so switching
skins at the same mode left the WebGL canvas painted with the old tint
until reload. Key the resolve off themeName too. Also trim the palette
comments.
* chore(desktop): drop redundant terminal theming header comment
Browse + install color themes from the VS Code Marketplace straight from
Cmd-K and Settings → Appearance. The Electron main process resolves the
extension, unzips the .vsix with a hand-rolled zip reader (zlib only, no
new deps), and hands back the raw theme JSON; the renderer converts it to
a DesktopTheme with a small seed → color-mix mapping.
- Folds an extension's light + dark variants into one theme family, so the
light/dark toggle switches Solarized/GitHub variants and installing in
dark mode stays dark.
- Guarantees accent contrast (WCAG AA) so imported sidebar labels read
instead of vanishing into the surface.
- Filters icon/product-icon packs out of the Themes-category search.
- "Install theme…" lives atop the Cmd-K theme picker; imports fold into
the Light/Dark groups by the modes they support.
Pops a session into a standalone, focused window for side-by-side work.
A secondary window loads the renderer at the session route with a
?win=secondary flag (ahead of the HashRouter '#'); it drops the global
sidebar plus the install/onboarding overlays and renders a single chat,
sharing the one local gateway over WS (no backend duplication). The main
process keys windows by sessionId so re-opening focuses the existing one
and self-cleans on close.
Open it via:
- ⌘-click (mac) / ⌃-click (win/linux) a sidebar session — the universal
"open in new window" gesture. Archive moves to the ⋯ / right-click menus
only, off the easy-to-misfire modifier-click.
- "New window" in the session ⋯ and context menus (link-external icon,
i18n'd across en/ja/zh/zh-hant).
A standalone window has no left rail, so AppShell treats its edge as
uncovered and applies the titlebar inset — the chat title clears the
macOS traffic lights instead of hiding behind them.

The chat transcript reaches the screen through a requestAnimationFrame-gated
flush (useSessionStateCache). The main BrowserWindow never set
backgroundThrottling, so Chromium paused rAF and clamped timers whenever the
window was blurred or occluded -- the live answer would stall until the window
regained focus or the user refreshed. In practice this bit any time Hermes
wasn't the focused window mid-turn (typing in your editor while the agent
replies, detached devtools, another window on top), presenting as "thinking,
no text, have to refresh."
Opt the renderer out of background throttling so a streaming chat app actually
streams in the background:
- backgroundThrottling: false on the main window (matches the secondary
windows that already set it)
- disable-renderer-backgrounding / disable-backgrounding-occluded-windows /
disable-background-timer-throttling at the process level for the
occlusion case
Latent since the desktop app landed (#20059), not a recent regression.
HERMES_DESKTOP_REMOTE_URL forces a remote connection but never writes
connection.json, so the gateway panel read mode/url from persisted config
and mislabelled an env-remote session as local with no url.
