Hot-path pass following the switch-latency work. Four independent costs,
one theme — work that runs on every boot or every turn but only needed
to run on actual change:
- electron: start the Python backend in parallel with the renderer load
instead of on did-finish-load. The backend cold boot is the dominant
startup cost and was serialized behind Chromium's load; the connection
promise is shared, so the renderer's getConnection() joins the
in-flight boot, and its getBootProgress() pull on mount recovers any
progress events emitted before the renderer was listening.
- boot/soft-switch: after the socket connects, run the independent
post-connect fetches (cwd seed, config, session lists) concurrently
instead of serially — profile adoption still lands first because the
session fetch scopes by it.
- session.info: config refetch is now gated to the foreground context
and coalesced (one trailing fetch per event burst) — it used to fire
two REST calls per event, including background sessions' heartbeats.
model-options invalidation now requires a VALUE change vs the
session's cached runtime state; the backend stamps model/provider on
every event, so the presence-typed flags refetched the provider
catalog once or twice per turn for a model that never changed.
- turn complete: sidebar refreshes (recents + cron + messaging fan-out,
each scanning profile state.dbs server-side) coalesce across
near-simultaneous completions; $sessions and profile totals keep
their identity when a refresh returns content-identical rows (same
signature gate cron/messaging already use), and the loading flag no
longer flickers over a populated list.
node-pty's published npm tarball ships the POSIX `spawn-helper` with mode
0644 (no exec bit). node-pty `posix_spawnp`s that helper on macOS/Linux, so a
non-executable copy fails every embedded-terminal spawn with
`Error: posix_spawnp failed.`. Packaged builds are unaffected because
stage-native-deps.mjs chmods the staged copy, but the dev flow
(`npm run dev` -> `electron .`) resolves node-pty straight from node_modules,
which nothing chmods -- so the first terminal in dev always dies.
Restore the exec bit once, lazily, right before the first spawn, via a small
DI-testable helper. Idempotent: already-executable copies (packaged builds)
are left untouched, and stat/chmod failures are collected and logged rather
than thrown so terminal startup never breaks.
* fix(desktop): trust Windows system CAs for remote gateways
Load Windows-trusted roots into Node's default TLS context before Desktop probes remote backends, while preserving bundled and extra CAs.
* test(desktop): cover Windows system CA installation
Verify existing trust roots survive the merge and that unsupported or unavailable stores fail open without changing TLS defaults.
Reassert the persisted webContents zoom after BrowserWindow moved, covering Windows monitor transitions where Chromium recalculates display scaling and drops the user-selected zoom.
Rebased onto current main, where the electron test harness migrated from
node:test to vitest (test:desktop:platforms = `vitest run --project electron`,
auto-discovering electron/*.test.ts). Swap the node:test import for vitest and
drop the .ts-extension import hack; the obsolete package.json node --test list
edit is dropped in the cherry-pick resolution since vitest auto-discovers.

Skip argv ownership verification after the remote PID is already proven dead, then remove only the validated lock/log metadata and continue with a fresh spawn.
Add SSH as a separate saved connection shape while preserving Cloud URL/OAuth semantics, inactive SSH drafts, strict host/port normalization, and profile-specific precedence.
hermes update is a Python CLI writing to a pipe when the Tauri updater or
the desktop's in-app POSIX path spawns it, so CPython block-buffers stdout.
Long quiet steps stream nothing to the progress UI. Worst case is the
pre-update backup (updates.pre_update_backup: true): it can zip multi-GB
archives for minutes while the updater still shows the previous line
('waiting for Hermes to exit...'). Users read that as a hang, cancel a
healthy update, and the orphaned child keeps mutating the install.
Set PYTHONUNBUFFERED=1 in both spawn sites (update_child_env in the Tauri
updater, applyUpdatesPosixInApp in the desktop) so output streams line by
line.
Also make the lock-probe unit test pass on macOS: the packaged payload
lives under Contents/Resources there, and Path::ends_with is
case-sensitive, so the lowercase resources/app.asar assertion only ever
matched the Windows/Linux layouts.

The CI change classifier routes package.json / package-lock.json /
.ts/.tsx changes to the frontend lane, not the Python lane. Four
Python tests asserted about these JS-side artifacts, so a PR touching
only those files would skip the Python suite — the regression goes
green on the PR and red on main (where the classifier fails open).
Ported all four to vitest so they run in the correct CI lane:
tests/test_package_json_lazy_deps.py
→ apps/desktop/electron/package-json-lazy-deps.test.ts
(camofox is lazy, agent-browser is eager, lockfile clean)
tests/test_desktop_electron_pin.py
→ apps/desktop/electron/desktop-electron-pin.test.ts
(electron dep is exact, matches build.electronVersion, lockfile agrees)
tests/test_assistant_ui_tap_compat.py
→ apps/desktop/electron/assistant-ui-tap-compat.test.ts
(@assistant-ui cluster shares one tap version + semver helper)
tests/test_dashboard_sidecar_close_on_disconnect.py
→ web/src/lib/chat-sidebar-session-params.test.ts
(sidecar session.create opts into close_on_disconnect + profile)
The ChatSidebar test was regex-matching .tsx source text (the
source-reading anti-pattern). Extracted sidecarSessionCreateParams()
from the component's effect into an exported pure function so the
test calls real code instead of pattern-matching a string.
Verified: 8 electron tests + 76 web tests pass; both typecheck clean.
CI runners have no global git identity. The remote repo seed commit
needs inline -c user.email/user.name flags, matching the pattern
already used by ensureGitRepo.
When "new worktree" branches off a remote-tracking ref like origin/main,
`git worktree add -b <branch> <dir> origin/main` auto-sets upstream
tracking (branch → origin/main), producing `branch:origin/main` in branch
listings. The user wants a standalone local branch — like `git checkout
origin/main && git checkout -b branch` — not one silently wired to the
remote. Add `--no-track` when the base is an `origin/` ref. Local branch
bases are unaffected (they never triggered tracking).
On Linux, Electron's safeStorage requires the --password-store Chromium
switch to select the correct keychain backend. Without it,
isEncryptionAvailable() returns false, hardening.ts refuses to persist
remote gateway tokens, and users are forced back to the
HERMES_DESKTOP_REMOTE_URL / HERMES_DESKTOP_REMOTE_TOKEN env fallback.
- hermes_cli/main.py: _detect_linux_password_store() probes KDE session
env vars, GNOME Keyring's control socket, then a D-Bus ping of
org.freedesktop.secrets (covers any Secret Service implementation,
e.g. KeePassXC). The result is bridged into the desktop subprocess env
as HERMES_DESKTOP_PASSWORD_STORE for both source and packaged launches.
- The user override lives in config.yaml (desktop.password_store,
default "auto") rather than a new user-facing HERMES_* env var, per
AGENTS.md. An explicit HERMES_DESKTOP_PASSWORD_STORE env var still
wins over config and detection, matching desktop.disable_gpu
semantics.
- apps/desktop/electron/bootstrap-platform.ts:
resolveLinuxPasswordStore() validates the bridged value; main.ts
applies it via app.commandLine.appendSwitch('password-store', ...)
before app ready. Unknown values log a warning and are skipped.
- Tests: detector + bridging coverage (packaged and source launch
paths, config override, env-var precedence, linux-only gating) in
tests/hermes_cli/test_gui_command.py; resolver coverage in
bootstrap-platform.test.ts (vitest electron project).

alelpoan's fix (emit hermes:zoom:changed after restore) is correct, but the
bug's root is duplication: setAndPersistZoomLevel and restorePersistedZoomLevel
each independently did setZoomLevel + send, and restore forgot the send.
Collapse both (and the lifecycle re-assert) into a single applyZoomLevel()
helper in zoom.ts that always applies-then-notifies — the regression can't
recur by omitting a send. Replace the source-grep test (which broke on main:
the sibling source-assertion pet test it copied was refactored to a behavioral
one, dropping the fs/path imports it relied on) with behavioral coverage of the
funnel, matching zoom.ts's "unit-testable without booting a BrowserWindow"
convention.

Extracted zoomWiringForWindowKind() + ZOOM_WINDOW_CONFIG into zoom.ts so
the pet-overlay-
opts-out / chat-windows-keep-zoom contract is tested via the pure
config,
not by reading source. Callers in main.ts now use
zoomWiringForWindowKind()
instead of inline { zoom: false } / default { zoom: true }.
oauth-session-request.test.ts regexed main.ts source text (extracting the
fetchJsonViaOauthSession function body and matching regexes against it) to
check Electron net.request doesn't set the forbidden Content-Length header
and does call request.write(body).
That behavior is already covered for real by oauth-net-request.test.ts,
which imports the actual serializeJsonBody/setJsonRequestHeaders helpers
from oauth-net-request.ts and asserts on a mock request object's setHeader
calls -- it only needed its relative import corrected to include the .ts
extension (Node's ESM loader doesn't resolve extensionless relative
specifiers). Removed the now-fully-superseded oauth-session-request.test.ts
and its dangling package.json wiring.
profile-delete-respawn.test.ts regexed main.ts source text to check that
prepareProfileDeleteRequest returns the torn-down profile name, and that
the hermes:api ipcMain handler captures that return value and routes to
the primary backend instead of respawning a pool backend for the just-
deleted profile.
Extract the pure decision logic into profile-delete-routing.ts (no
Electron import):
- profileNameFromDeleteRequest(request): parses a DELETE
/api/profiles/<name> path, moved verbatim (already pure).
- decideProfileDeleteAction(profile, deps): the branch decision (noop /
teardown-primary / teardown-pool) and the profile name to return,
parameterized over isDefaultProfile/isValidProfileName/primaryProfileKey.
- resolveRouteProfile(tornDownProfile, profile): the
routing ternary from the hermes:api
handler.
prepareProfileDeleteRequest in main.ts now calls decideProfileDeleteAction
for the decision and only performs the async side effects (teardown +
writeActiveDesktopProfile) the decision calls for.
profile-delete-routing.test.ts replaces profile-delete-respawn.test.ts
(which was never wired into test:desktop:platforms), importing the pure
functions directly and asserting real return values across every branch
-- no readFileSync, no regex-on-source. Wired the new test file into
test:desktop:platforms in package.json.
windows-hermes-resolution.test.ts regexed main.ts source text to check
three Windows resolution bugs that caused desktop reinstall loops:
1. findOnPath()'s PATHEXT extension order (must try real extensions before
the empty one, or an extensionless Git-Bash hermes shim shadows
hermes.cmd/.exe).
2. handOffWindowsBootstrapRecovery()'s --update vs --repair choice (must
gate on any real-install signal, not just the hermes.exe shim).
3. unwrapWindowsVenvHermesCommand()'s probe-before-trust behavior (must
canImportHermesCli() before returning a venv python, or a broken venv
gets re-selected forever).
Extract all three into pure, dependency-injected functions in
windows-hermes-path.ts (no Electron import): buildPathExtCandidates(),
chooseUpdaterArgs(), resolveVenvHermesCommand(). main.ts's
findOnPath/handOffWindowsBootstrapRecovery/unwrapWindowsVenvHermesCommand
now call these with their existing helpers (fileExists, canImportHermesCli,
getVenvPython, etc.) passed through as deps.
windows-hermes-path.test.ts replaces windows-hermes-resolution.test.ts,
importing the pure functions directly and asserting real return values
with fake/injected dependencies (fake venvs, fake probes) -- no readFileSync,
no regex-on-source.
windows-child-process.test.ts regexed main.ts and bootstrap-runner.ts
source text to check that spawn/execFileSync call sites wrapped their
options with hiddenWindowsChildOptions(), and that backend teardown
chose the right kill strategy.
Extract both into dependency-free sibling modules:
- windows-child-options.ts: hiddenWindowsChildOptions(options,
isWindows)
now takes isWindows as an injectable param (defaults to the real
platform check). main.ts and bootstrap-runner.ts both import the same
implementation instead of each defining their own copy.
- backend-child.ts: stopBackendChild(child, deps) with
forceKillProcessTree
and isWindows injected, so the SIGTERM-vs-tree-kill branching is
directly
testable with a fake child + a spy.
windows-child-options.test.ts replaces windows-child-process.test.ts,
calling the real functions with fake spawn/execFileSync-shaped objects
and asserting on the actual returned options / kill call.
When the base is an origin/… ref, fetch just that branch so the
local tracking ref is fresh before `git worktree add -b new origin/main`.
Fetch failures (offline / no remote) are silently ignored — git uses
whatever local ref exists, or raises a clear error if it's missing.
The sidebar "New worktree" button branched off whatever HEAD you were
on — now a filterable Popover+Command combobox lets you pick any local
or remote-tracking branch as the base, defaulting to origin/HEAD.
Backend listBaseBranches() queries refs/heads + refs/remotes via
for-each-ref, flags origin/HEAD (falling back to the local default for
no-remote repos). Mirrored on the Python REST API side
(base_branch_list + /api/git/base-branches route).
When the desktop UI runs on Windows and the gateway runs in WSL, a WSL/POSIX
cwd isn't openable/readable from the Windows host. Add wsl-path-bridge.ts to
translate the Windows-side direction only:
- native folder dialog defaultPath: `/home/...` → `\\wsl.localhost\<distro>\...`
- fs read path: WSL cwd → its UNC / `C:\` drive form
Distro detection reads `wsl.exe -l -q` with `WSL_UTF8=1` and strips stray NUL
bytes, since older wsl.exe emits UTF-16LE (microsoft/WSL#4607) — the original
utf8 read returned a garbled distro name. UNC uses `\\wsl.localhost\` with a
`\\wsl$\` fallback for older Windows. The reverse (any path → POSIX) is handled
once gateway-side, so the picker result needs no desktop translation.

A reopened tab restarted the shell in its original launch dir, so the fresh
prompt showed the wrong folder after a prior `cd` (the issue's "separate
thing" note). Track the shell's working directory and restart the PTY there.
Two independent signals feed a persisted per-tab restoreCwd:
- a main-side PTY cwd probe (shell-agnostic; /proc on Linux, lsof on macOS;
Windows has no cheap per-process query so it falls back to the launch dir)
- cwd-reporting OSC sequences parsed in the renderer (OSC 7 file URIs, OSC 9;9
ConEmu/Windows-Terminal paths) for shells configured to emit them
On relaunch the fresh shell boots in restoreCwd, falling back to the launch
cwd (then home) when it no longer exists.
scripts/desktop-sandbox.sh runs a Hermes desktop instance in an isolated
sandbox — separate HERMES_HOME, separate Electron userData, and a
distinct
app name (HERMES_DESKTOP_APP_NAME) so it doesn't compete with the main
desktop instance's single-instance lock.
Two modes:
- Ephemeral (default): temp dir, cleaned up on exit
- --persistent: stored under .hermes-sandbox/ in the worktree git root,
survives restarts for repeat testing
In the Nix devShell the script is available as 'sandbox'.
Also makes APP_NAME overridable via HERMES_DESKTOP_APP_NAME in main.ts —
app.setName() runs before requestSingleInstanceLock(), so the overridden
name changes the lock key. collectRelaunchEnv already preserves
HERMES_DESKTOP_* vars through self-update relaunches; test updated to
cover the new env var.
