teknium1 5d2acf7066 test(desktop): pin deferred launcher-entry writes and the terminal-launch control 
- cmd_gui with DESKTOP_STARTUP_ID: the entry is installed only after the fake Electron
  writes the reveal byte to HERMES_DESKTOP_READY_FD (spawn precedes install).
- cmd_gui without DESKTOP_STARTUP_ID (control): install still precedes the spawn.
- DeferredDesktopEntryInstall.finish(): an app that exits without revealing heals
  exactly once, after the exit.
- linux-launcher-ready: one byte, fd closed, variable consumed; garbage/absent = no-op.

Docs: user-guide/desktop.md explains when the entry write happens for grid launches.

Teknium 0e78694c72 simplify(compat): hermes_cli.main — drop 198 re-exports/aliases (155 eager + 45 lazy PEP 562 + _warn_stale_dashboard_processes alias + _time/_self/_LAZY_* machinery), repoint 17 source callers + 91 test files 2026-09-03 15:07:39 -07:00
Teknium 1398c0f5ca fix(update): stage-and-swap the Desktop rebuild so a failed pack never removes the working app 
`hermes update` → `hermes desktop --build-only` → `npm run pack` packed
electron-builder's output IN PLACE: before-pack.mjs wipes
`release/<platform>-unpacked` (or the mac `Hermes.app`) before the Electron
unpack/asar/rename, so any failure after that point — corrupt cached zip,
blocked download, missing dep, disk full — left the user with NO app and the
update reporting "partially complete" over an empty release/ (#86443).

Fix the class, not the predicate: cmd_gui now passes
`-c.directories.output=apps/desktop/.staging-<pid>-<ts>` to the pack, runs
the existing verification (packaged-exe probe, macOS re-sign, Windows PE
integrity gate) against the STAGED tree, and only then promotes it:
`release/<unpacked>` → `.previous`, `<staging>/<unpacked>` → `release/<unpacked>`,
drop `.previous`. A rename failure between the two steps restores `.previous`.
On any failure the staging dir is removed and the live app is untouched.

- `_purge_electron_build_cache` / `_ensure_desktop_exe_launchable` /
  `_desktop_macos_relaunchable_fixup` take the output dir so the corrupt-zip
  retry purge and the integrity self-heal only ever clear the staging tree,
  never `release/*-unpacked`.
- `.gitignore` the staging dir so a killed build cannot dirty the checkout.
- Docs: updating.md describes the stage-and-swap Desktop rebuild step.

Live repro (real `_rebuild_desktop_after_update` → real `hermes desktop
--build-only` subprocess, fake npm whose pack wipes appOutDir then fails):
before — `release/linux-unpacked/hermes` gone after the failed rebuild;
after — marker intact, no `.staging-*` left, rebuild returns False; a
passing pack swaps the new app into `release/`.

Closes #86443

lesseradmin 779482598f fix(desktop): pass --disable-setuid-sandbox on the userns launch path 
When chrome-sandbox is present but not root-owned 4755, Chromium can still
abort via setuid_sandbox_host even though the namespace sandbox works.
After the userns probe skips sudo, append --disable-setuid-sandbox so
.desktop/no-TTY launches keep the namespace sandbox without a privilege
prompt. Does not add --no-sandbox.

Fixes #51327

David Metcalfe c0b5a8e15d fix(desktop): return True when fallback sign + strict verification succeed 
The legacy ad-hoc fallback signed and verified successfully but still
fell through to return False, contradicting the fixup's documented
contract. The success witness codified the contradiction. Return True
on the verified success path; the caller ignores the return value, so
no behavior change beyond the contract correction.

David Metcalfe 177688e31e fix(desktop): never delete safeStorage keychain item in the updater 
Addresses round-2 review feedback on #90961. The previous commits
scoped the keychain deletion to the legacy ad-hoc fallback, but the
reviewer correctly held the blocker: the fallback ran codesign with
check=False, ignored the result, and unconditionally deleted 'Hermes
Safe Storage' — permanently orphaning gateway and native OAuth
credentials even when signing failed or a configured identity had
failed and routed into the fallback.

This commit removes the deletion entirely:
- _desktop_macos_reset_keychain_safe_storage is gone; no code path
  touches the keychain item anymore.
- The legacy fallback now checks the codesign result and runs
  codesign --verify --deep --strict; any failure leaves the item
  untouched and prints a warning.
- The keychain prompt after an ad-hoc re-sign is recoverable
  (Always Allow updates the ACL partition list and preserves the
  key); deletion is not. The durable proof-carrying migration
  belongs in Electron (safeStorage can read the old key) and is
  tracked as a follow-up.

Tests: 4 witnesses (stable path, default no-config success, fallback
failure, fallback success) all mutation-verified against both the
deletion regression and the ignored-codesign-result regression.

David Metcalfe 368ea2d88b test(desktop): mark keychain-reset scoping tests macos_only 
The fixup no-ops on non-macOS (sys.platform guard), so the new
regression tests must carry the same @pytest.mark.macos_only marker
as their siblings (test_relaunchable_fixup_falls_back_to_legacy_adhoc_on_failure).
Without it the legacy-adhoc test failed on the Linux CI runner where
the fixup returns True before reaching the reset path.

David Metcalfe 91dcca9a9b fix(desktop): scope keychain reset to the legacy ad-hoc fallback only 
The previous commit deleted the 'Hermes Safe Storage' keychain item after
every successful re-sign, including the stable certificate-anchored
identity path. On that path the designated requirement is stable across
rebuilds, so after the first launch under the new identity the keychain
ACL already matches; deleting the item on every update permanently
orphaned gateway-token and native-OAuth credentials that were working
fine (both are safeStorage-backed: electron/main.ts connection config
and native-oauth-tokens.json).

Addresses review feedback on #90961:
- Rename _desktop_macos_update_keychain_acl -> _desktop_macos_reset_keychain_safe_storage (it deletes, it does not update an ACL).
- Only invoke it on the legacy ad-hoc fallback path, where every rebuild
  produces a new cdhash so the ACL can never match and the alternative
  is a recurring prompt. The trade-off (re-enter credentials once per
  update) is documented; the durable fix is a stable signing identity.
- Add regression tests: stable path must NOT reset, ad-hoc fallback MUST.

Teknium 28f2ea86e2 fix(desktop): make --setup-tcc-identity produce a VALID signing identity on modern macOS 
Fixes the two live E2E blockers @ctaylor86 found on PR #77189 (macOS 26.3.1,
OpenSSL 3.6.3):
- retry the PKCS#12 export with -legacy when security import rejects the
  OpenSSL 3 default format ('MAC verification failed during PKCS12 import')
- trust the self-signed root for the codeSign policy (security
  add-trusted-cert -r trustRoot -p codeSign) — an imported-but-untrusted cert
  is invisible to find-identity -v and unusable by codesign
- gate success on find-identity -v -p codesigning (postcondition), and use
  the same -v probe for idempotency so an untrusted leftover cert is repaired
  instead of reported as done

Tests rewritten as stateful fakes (valid only after import+trust), plus new
coverage for the -legacy retry, trust failure, postcondition gate, and the
untrusted-cert repair path; sabotage-verified (reverting to the name-in-output
probe fails 4 tests). Docs: manual fallback now includes the Trust step.

CriptoGus eeb391d0b1 feat(desktop): add --setup-tcc-identity to keep macOS TCC grants across rebuilds 
Adds a one-shot `hermes desktop --setup-tcc-identity` command that creates a
self-signed code-signing certificate in the login keychain (openssl +
security import), grants codesign access to it, writes
desktop.macos_signing_identity to config.yaml, and re-signs the packaged app
with a certificate-anchored Designated Requirement.

macOS persists permission grants (Full Disk Access, Accessibility, Files and
Folders, microphone) against the app's code-signing identity, not its path.
The default identifier-pinned ad-hoc signature is stable across rebuilds, but
a certificate-anchored identity is the strongest guarantee — the same
mechanism yabai/skhd rely on. Previously users had to create the certificate
manually in Keychain Access; this command automates the whole flow and is
idempotent (re-run after updates).

Docs: desktop.md TCC section now leads with the command, keeps manual steps.
Tests: 4 new — fresh cert creation path, idempotent reuse, non-macOS no-op,
cmd_gui early-exit before build.

Brooklyn Nicholson b595fcd5e1 fix(desktop): keep the Linux HUD clickable and recoverable 
X11 cannot restore a window that has ignored the mouse, so stay solid
there. Native Wayland keeps click-through via the cursor poll. Add
desktop.ozone_platform_hint so COSMIC users can opt into XWayland for
always-on-top, and a layout reset that restores the default size.

Teknium 40712da40f test: adapt #41236 password-store tests to real-host _make_packaged_executable 
Main's helper no longer takes a platform kwarg (real-host layout since the
sys.platform-fake removal); mark the five password-store tests linux_only/
macos_only per the don't-fake-the-host policy, and stub the Linux desktop-entry
registration those cmd_gui runs now reach.

ethernet 30da5d0a89 test: run os-specific tests on their real host, not a faked one 
many tests patched sys.platform or a module's _IS_WINDOWS flag, then
ran on linux ci. the patch selects the branch under test, but the host
does not have the behavior the branch exists for. the test proves the
patch, not the platform. some gated assertions never ran on any host.

this commit adds three markers: linux_only, macos_only, windows_only.
a conftest hook skips a marked test on the other hosts, with a clear
reason. no test fakes a host now. two documented fakes remain
(android/termux, freebsd) because no ci runner exists for them.

each fake site got one of four treatments:
- gate it: the real host supplies the platform; mocks cover real
  dependencies only, never host identity
- patch the module's own probe when the subject is the probe's consumer
- assert against the real host when the fake stood in for any non-x host
- delete the patch when it set the value the host already has

bare skipif(sys.platform != ...) guards became markers too. the lane
model skips these on linux and never imports them on windows, so they
ran on no host. platform parametrize tables are now one marked test
per os.

running on real hosts found real errors: a chrome-sandbox failure in
test_gui_command that main hides, and two windows failures fixed here.
the agents.md testing section now documents the policy.

ethernet eea6044098 feat(desktop): register a Linux launcher entry for hermes desktop 
On Linux a freshly-built desktop app had no presence in the application
launcher: no Hermes in the KDE/GNOME menu, no icon, nothing to pin. Users
had to hand-write ~/.local/share/applications/hermes.desktop and remember
to reindex the menu caches themselves.

`hermes desktop` now writes that entry itself (best-effort, idempotent,
never blocking a launch), and `hermes uninstall --gui` removes it again.

Both fields that matter are absolute:

- Exec — the launcher runs with a minimal environment and no shell PATH
  customizations, so a bare `hermes desktop` silently fails for anyone
  whose hermes lives in ~/.local/bin or a venv. We resolve the real binary
  via relaunch.resolve_hermes_bin(), falling back to an absolute
  interpreter + `-m hermes_cli.main`.
- Icon — an unqualified name only resolves against an indexed icon theme,
  which we are not in. The spec allows an absolute path, so we point at
  apps/desktop/assets/icon.png in the checkout. No copy is installed: Exec
  already depends on that same tree, so a second copy would add bytes and
  an uninstall step without surviving anything Exec wouldn't.

Menu-cache refresh is tool-gated — update-desktop-database, then
kbuildsycoca6 or kbuildsycoca5 — each only when the binary is actually on
PATH, because most desktops ship none of them and a missing one is not an
error. The entry is only rewritten when its contents change, so a launch
doesn't churn the caches every run.

Verified on NixOS: the generated entry passes desktop-file-validate, a
real kbuildsycoca6 on PATH is invoked with --noincremental, a real
update-desktop-database writes mimeinfo.cache, absent tools are skipped
cleanly, and removal leaves the checkout's icon untouched.

Teknium 39975613b1 test: prune wave 2 + speed fixes — 28,106 → 19,757 test functions, suite wall 315s → 294s 
Second, deeper pass over tools/gateway/hermes_cli plus first pass over
the trees wave 1 missed (acp, acp_adapter, skills, computer_use, docker,
dashboard, conformance, monitoring, secret_sources, hermes_state,
providers). Same rubric as wave 1 (AGENTS.md test policy); security,
alternation/caching invariants, issue-number regressions, and E2E kept.

Real test-quality fixes found and rooted out along the way:
- tests/tools/test_command_guards.py made real auxiliary-LLM HTTPS calls
  (DEFAULT_CONFIG smart-approval leaked in) — pinned approval
  mode=manual via autouse fixture: 17.4s → 0.4s.
- test_model_switch_custom_providers.py / test_user_providers_model_switch.py
  silently probed live provider catalogs (~2s/test) — stubbed
  cached_provider_model_ids/provider_model_ids/fetch_api_models.
- test_telegram_noise_filter.py: 15-platform copy-paste matrix over
  shared gateway.run logic → 3 representative platforms (55s → 3.9s).
- test_gateway_shutdown.py: stop()'s 5s interrupt-deadline loop spun on
  MagicMock agents — interrupt.side_effect now clears _running_agents
  (22s → 1.0s).
- test_gateway_inactivity_timeout.py poll-harness timings shrunk 3-5x
  (24s → 1.1s); test_mcp_stability.py backoff/SIGTERM-grace sleeps
  patched (15.4s → 2.5s); test_async_delegation.py negative-drain wait
  5s → 0.5s.
- test_telegram_init_deadline.py: loop-block margin restored to 1.0s
  with rationale comment — the watchdog-dump assertion needs the loop
  blocked well past deadline+grace under parallel load (flaked once in
  the 40-worker verification run at a 0.2s margin).

Verification: full hermetic suite via scripts/run_tests.sh —
2,438 files, 21,718 tests passed, 0 failed, 293.9s wall.
Suite totals vs original baseline: 46,820 → 19,757 test functions
(−57.8%), wall 583.5s → 293.9s (−50%), subprocess CPU 13,564s → 11,623s.

Teknium 6b81590c55 test: prune low-value tests suite-wide (wave 1) — 46,820 → 28,106 test functions 
Systematic prune per AGENTS.md test policy, one pass over every major
test tree (gateway, hermes_cli, tools, agent, run_agent, plugins, cli,
cron, tui_gateway, honcho/openviking, root-level):

- DELETE: source-reading tests (read_text/getsource on prod files),
  change-detector tests (exact catalog counts, model-name snapshots,
  config version literals), mock-echo tests (assert a mock returns what
  it was told), assertion-free/trivial tests, near-duplicate
  parametrizations (boundaries + one representative kept), async/sync
  twin duplicates, cosmetic within-file variations.
- KEEP (mandatory): security/redaction/approval guards, message-role
  alternation invariants, prompt-caching/deterministic-call-id
  invariants, issue-number regression tests (deduped), E2E tests.
- 6 test files deleted outright (script-style/no-assert or fully
  redundant); conftest.py, fakes/, fixtures/ untouched.
- tests/acp/conftest.py added: autouse fixture stubs the live
  models.dev/GitHub/Copilot/Anthropic inventory fetches that ACP server
  tests performed on every session create — test_server.py 147s → 3.4s,
  and the tests are now genuinely hermetic.
- Sleep-based slowness shrunk where safe (codex_ttfb_watchdog,
  compression_concurrent_fork, etc.); no wall-clock assertion tightened.

Verification: full hermetic suite via scripts/run_tests.sh —
2439 files, 31,130 tests passed, 0 failed, 0 flaky retries, 315s wall
(baseline: 583s wall, 13,564s subprocess CPU).

Brooklyn Nicholson 812b75fdfc fix(desktop): refuse hardened-runtime sign when entitlement plists are missing 
Hardened-runtime restrictions are enforced even for ad-hoc signatures,
so signing with --options runtime without the allow-jit entitlements
would leave Electron/V8 crashing on launch — strictly worse than the
legacy plain ad-hoc sign. Raise instead, so the fixup falls back to the
legacy path and the bundle always stays launchable.
 2026-07-28 17:34:43 -05:00
Brooklyn Nicholson 5d171ffbbe fix(desktop): stable macOS signing identity so TCC grants survive rebuilds 
Local/self-updated macOS builds were finished with a plain
'codesign --force --deep --sign -', leaving a cdhash-only Designated
Requirement and stripping electron-builder's entitlements. Every rebuild
changes the cdhash, so TCC treats the new bundle as different code and
forgets Full Disk Access, Desktop/Downloads/Documents, Accessibility,
Automation, and microphone grants — users re-approve everything after
every update.

Rework the relaunch fixup to sign inside-out (standalone Mach-O
binaries, nested frameworks/helpers, then the main bundle), preserving
the repo's entitlement plists, and pin an identifier-based Designated
Requirement when signing ad-hoc so TCC has a stable identity to persist.
Opt-in desktop.macos_signing_identity names a persistent keychain cert
(self-signed Code Signing cert works — no Apple Developer account) for a
certificate-anchored DR, the strongest form. An intact Developer ID
signature is detected and never clobbered, callers can pass the
publisher-signing decision explicitly so a later dotenv load can't flip
it, and the legacy deep ad-hoc sign remains the last-resort fallback.

brooklyn! dfb76d36d5 fix(desktop): put Hermes-managed Node on PATH for install/rebuild (#66002) 
Desktop launch and the update-chain rebuild install npm deps whose child
scripts shell out to a bare `node` (e.g. electron-winstaller's
select-7z-arch.js). When launched from the desktop updater chain
(Desktop -> hermes-setup -> hermes update) the shell PATH customizations are
lost, so the install dies with `'node' is not recognized` / `node: not found`.

- cmd_gui: wrap the npm-install env with with_hermes_node_path(_nixos_build_env())
  so managed Node is prepended even on a stripped PATH — mirrors the idiom
  already used by the update deps refresh. (The original fix merged nixos_env
  on TOP of the managed env, whose full os.environ copy clobbered the managed
  PATH back to bare; wrapping fixes that merge order.)
- _cmd_update_impl: spawn the `desktop --build-only` subprocess with
  with_hermes_node_path() so the child starts with managed Node from the outset.

Regression test: the desktop install env now prepends the managed Node dir
ahead of a bare updater PATH instead of passing env=None.

Houston Searcy 66a2a4c15b feat(desktop): auto-detect Linux keychain backend for secure token storage 
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).

teknium1 c918d42d88 feat(desktop): config-driven Electron launch flags + GPU policy 
Adds a desktop: section to config.yaml so headless/VM users can make
`hermes desktop` launch correctly without a wrapper command:

- desktop.electron_flags: extra Electron CLI flags (e.g. --ozone-platform=x11)
  appended to every launch. Accepts a list or a shell-split string.
- desktop.disable_gpu: auto|true|false, bridged to the HERMES_DESKTOP_DISABLE_GPU
  env var the Electron app already reads. An explicit env var still wins.

cmd_gui() reads these via _desktop_launch_options() and applies them. This is
the config.yaml form of the capability proposed as a raw env var in #38934
(@1RB) — behavioral settings belong in config.yaml, not a new HERMES_* env var.

Rafael Millan 54ea059919 fix: fall back to no-sandbox for desktop launch on restricted Linux hosts 2026-06-27 22:16:20 -07:00
ailthrim 25ec01f79f fix(desktop): don't purge Electron cache / mirror-retry after a late build failure 
`hermes desktop` / `hermes update` recover from a corrupt Electron download by
purging the cached zip + re-downloading and retrying the pack, and then by
falling back to a public mirror. That recovery is only meaningful when the
packaged executable is MISSING — the signature of a partial/corrupt unpack.

A LATE failure such as macOS code signing (#40187) leaves
`Hermes.app/Contents/MacOS/Hermes` (or the platform equivalent) in place.
Re-downloading Electron can't repair a signing failure, so the purge +
slow mirror retry just grind through another identical failure before the
build finally errors out.

Gate both recovery blocks on `_desktop_packaged_executable(desktop_dir) is None`
so a build that already produced the executable fails fast instead of
triggering the destructive download recovery. The corrupt-download path
(executable missing) is unchanged.

Salvage of #42782, re-applied onto current main (the surrounding recovery was
refactored to `_electron_dist_ok` / `_redownload_electron_dist` since the PR
was opened). Adds a regression test asserting no purge / mirror retry runs when
the executable exists, and updates the existing retry/mirror tests to model the
corrupt-download case (executable absent) the recovery is actually for.

Related to #40187 (the residual cache-purge sub-issue; the signing failure
itself is fixed by #52591).

Brooklyn Nicholson 1d9ed7f48a fix(desktop): ad-hoc sign macOS self-update rebuilds 
The desktop self-updater rebuilds and re-signs the .app on each user's own
machine (`hermes desktop --build-only` -> electron-builder `--dir`). With
CSC_IDENTITY_AUTO_DISCOVERY on (its default), electron-builder signs the
type=distribution, hardened-runtime bundle with whatever identity is in that
user's keychain -- typically a personal "Apple Development" cert -- which
stalls/fails the sign step (no Developer ID, no provisioning profile) or
clobbers the original notarized signature with an unusable one, tripping
Gatekeeper on every post-update launch.

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

brooklyn! c1f9eb0ec4 fix(desktop): resolve electronDist dynamically + self-heal blocked installs (supersedes #48081/#48082) (#48091) 
* fix(desktop): resolve electronDist dynamically + self-heal blocked installs

Supersedes the static-path approach (#48081) and the install-step self-heal
(#48082) with a fix that removes the whole failure class instead of chasing each
symptom. Three distinct faults converged into the June desktop-build outage; this
closes all three.

Root cause (the part #48081 left open — "Gap B"):
  build.electronDist was a static relative path in apps/desktop/package.json, but
  npm workspace hoisting is NOT deterministic — depending on the npm version and
  what else is installed, npm nests the workspace-only electron devDep under
  apps/desktop/node_modules/electron OR hoists it to the repo root. A static path
  matches only one layout, so a clean install intermittently fails with "The
  specified electronDist does not exist". #48081 re-pointed the path at the
  nested layout (correct today) but electron-builder reads electronDist
  STATICALLY, so any future hoist change silently breaks it again — only caught
  by a CI invariant, never self-corrected.

Fix:
- scripts/run-electron-builder.cjs: resolve electron the way Node's runtime does
  — require.resolve("electron/package.json") walks node_modules from the desktop
  project upward and finds electron wherever npm actually put it. The path can
  never drift out of sync with the install layout again, on any OS/npm version.
    * dist present -> pass -c.electronDist=<abs>/dist so electron-builder reuses
      the unpacked runtime (keeps the #38673 fast path that dodges the 26.8.x
      missing-binary re-unpack bug).
    * dist absent  -> omit electronDist; electron-builder fetches Electron itself
      via @electron/get honoring electronVersion + ELECTRON_MIRROR.
  package.json: builder script now runs the wrapper; the static build.electronDist
  is removed (the resolver owns it).
- main.py / install.sh / install.ps1: on a dependency-install failure where the
  electron package staged but its dist is missing (electron's install.js
  process.exit(1) on a blocked/throttled binary download — #47266/#47917/#48021),
  repopulate the dist via electron's downloader (canonical, then npmmirror.com)
  and CONTINUE to the build instead of aborting. npm runs postinstall LAST, so
  the only casualty is electron/dist; bailing here is what made the pack-time
  mirror self-heal unreachable on a blocked network. Hard-fail only when electron
  never staged at all (a genuine dependency error).
- The pack-time mirror fallback now retries the build even when the pre-fetch
  can't populate the dist: the wrapper lets electron-builder download Electron
  itself via the mirror, so the retry is no longer a no-op (it was, when
  electronDist was a static path).

The exact 40.10.2 pin (already on main) keeps the third mode — the native
@electron-internal/extract-zip win32 binding that 40.10.3/40.10.4 ship without a
published prebuild — from recurring.

Tests:
- test_desktop_electron_pin.py: replace the static-path-matches-lockfile
  invariant with contracts that there is no hardcoded electronDist to drift, the
  builder script routes through the resolver, and the resolver uses Node module
  resolution + injects -c.electronDist.
- test_gui_command.py: install-failure self-heal continues to build; genuine
  (electron-never-staged) install failure still hard-fails; pack retries under
  the mirror even when the pre-fetch is blocked.

* fix(desktop): narrow Electron self-heal to real missing-dist failures

Follow-up on #48091 to remove the remaining misdiagnosis risk from the
installer/build fallback path (#46785 concern): only take the Electron
repair/retry path when Electron's package files are staged and dist is actually
missing/corrupt.

- main.py: add _electron_pkg_staged_missing_dist() and use it to gate install
  failure recovery; fail fast for unrelated npm install errors.
- main.py/install.sh/install.ps1: run cache purge + retry only when dist is
  missing; do not retry unrelated tsc/vite/build failures under an
  Electron-specific narrative.
- install.sh/install.ps1: tighten install-stage self-heal guard to require both
  package.json + install.js and missing dist.
- tests: add coverage that install failure hard-fails when Electron dist already
  exists, and update retry test to reflect the tightened recovery condition.

Validation:
- Python tests: 64 passed
- install.sh-related tests included in the run
- Real mac build on this machine:
  - npm ci at repo root: success
  - cd apps/desktop && npm run pack: success
  - electron-builder packaged darwin arm64 and used custom unpacked Electron dist

* refactor(desktop): trim electron self-heal helpers and comments

Deduplicate mirror-retry into _try_redownload_electron_dist / shell
counterparts; shorten wrapper and install-script commentary without
changing recovery semantics.

Teknium f8098c6b6f fix(desktop): resolve electronDist to the actual electron install location (#48081) 
After the June lockfile regeneration (#46652) floated electron and reshuffled
npm workspace hoisting, the desktop pack fails with "The specified electronDist
does not exist". apps/desktop/package.json pointed electronDist at the repo
root (../../node_modules/electron/dist) while npm now installs electron nested
under apps/desktop/node_modules/electron. The two contradict, so a clean
install can never package the app (Windows + macOS).

- electronDist -> node_modules/electron/dist (resolved relative to apps/desktop,
  i.e. the workspace-local install npm actually produces).
- hermes_cli/main.py, scripts/install.sh, scripts/install.ps1: add a runtime
  electron-dir resolver that prefers apps/desktop/node_modules/electron and
  falls back to the root hoist, so dist checks + the mirror re-download work
  under either npm layout.
- patch-electron-builder-mac-binary.cjs: try the workspace-local Electron.app
  before the root hoist in the macOS binary-restore fallback (sibling site no
  PR touched).
- test: assert build.electronDist resolves to where the lockfile installs
  electron, so a future hoist change (root <-> nested) can't silently break it.

Salvages the overlapping work in #48003 (sitkarev), #48012 (omegazheng), and
#48033 (james47kjv).

xxxigm d1ecebcbfd fix(desktop): re-download Electron binary via mirror when pack fails (#47266) (#47276) 
* fix(desktop): re-download Electron binary via mirror when pack fails (#47266)

Since #38673 pinned build.electronDist to node_modules/electron/dist,
electron-builder reads the Electron binary straight from there and never
downloads it during `npm run pack`. That dist tree is only produced by the
electron package's postinstall (install.js) during `npm ci`. When that
download is blocked or throttled (GitHub's release host is unreachable in
some regions), the dist is missing and the build dies with:

    The specified electronDist does not exist: .../node_modules/electron/dist

The existing ELECTRON_MIRROR fallback in all three desktop-build paths
(scripts/install.ps1, scripts/install.sh, and `hermes desktop` in
hermes_cli/main.py) re-ran `npm run pack` with ELECTRON_MIRROR set — but
pack never downloads Electron anymore, so the mirror was never used and the
retry re-read the same missing dist. The fallback was effectively dead.

Drive the mirror through electron's own downloader instead:

- Add a dist-presence check + a downloader helper (Test-ElectronDist /
  Restore-ElectronDist, _electron_dist_ok / _restore_electron_dist,
  _electron_dist_ok / _redownload_electron_dist) that wipes a partial dist
  + the path.txt version marker (electron's install.js short-circuits on it)
  and re-runs `node install.js`, optionally via a mirror.
- On the first retry, repopulate a missing dist from the canonical source;
  on the mirror retry, re-fetch through npmmirror.com, then pack.
- Gate the re-download on the dist check so an unrelated build failure
  (tsc/vite) doesn't trigger a pointless ~200 MB refetch, and skip the final
  pack when the binary still can't be fetched instead of failing the same way.

* test(desktop): cover Electron dist re-download mirror fallback (#47266)

Add behavior coverage for the electronDist re-download fix:

- _electron_dist_ok across linux/win32/darwin, including the partial-dist
  case (dir present but binary missing) that makes the pinned electronDist
  fail.
- _redownload_electron_dist: no-op when the binary is present, bail when
  install.js is absent, wipe a stale dist + path.txt marker and run
  electron's downloader with ELECTRON_MIRROR injected, and report failure
  when the download still produces no binary.
- `hermes desktop`: the mirror fallback now drives electron's own downloader
  before re-running pack, and skips the final pack entirely when the binary
  can't be fetched.

Replaces the old mirror test that asserted the (now-fixed) dead behavior of
re-running `npm run pack` with ELECTRON_MIRROR set — pack never downloads
Electron under the pinned electronDist, so that retry could never help.

brooklyn! ba44de06da fix(install): self-heal a stuck Electron download (salvage of #42894) (#42998) 
* fix(install): self-heal a stuck Electron download on the desktop build

The desktop build downloads Electron (~114MB) from GitHub. A corrupt cached
zip, or a blocked/throttled GitHub release host (the repeating "retrying" log),
hard-failed the install — and install.sh had no recovery at all while
install.ps1 / `hermes desktop` only purged the cache.

All three build paths now escalate on a failed `npm run pack`:
GitHub → purge corrupt electron-*.zip + stale *-unpacked and retry → one retry
via a public Electron mirror (npmmirror.com). @electron/get SHASUM-verifies the
download, and a user-pinned ELECTRON_MIRROR is always respected (never
overridden). Adds a bash clear_electron_build_cache()/_desktop_pack() to mirror
the existing PowerShell/Python helpers.

* test(install): cover the Electron mirror fallback

Verify `hermes desktop` falls back to a mirror when the cache purge finds
nothing, and that a user-pinned ELECTRON_MIRROR is respected (no extra attempt,
not overridden).

* docs(desktop): troubleshoot a stuck Electron download

Document the automatic cache-purge + mirror fallback, how to pin your own
ELECTRON_MIRROR, and how to clear a corrupt cached zip by hand.

* docs(install): correct the Electron mirror trust framing

The mirror-fallback comments and the desktop troubleshooting doc implied
`@electron/get`'s SHASUM check makes the npmmirror.com download safe against
tampering. It doesn't: the SHASUMS256.txt is fetched from the same mirror, so
the check guards against a corrupt/partial download, not a compromised mirror.

Reframe all four surfaces (install.sh, install.ps1, `hermes desktop`, and the
docs) to state the trust trade-off honestly — npmmirror.com is the de-facto
Electron community mirror, we only fall back to it after the canonical GitHub
download fails, and a user-pinned ELECTRON_MIRROR is never overridden. No
behavior change.

xxxigm 96fd9d4979 fix(desktop): stop running Hermes.exe locking win-unpacked before Windows pack (#42100) 
* fix(desktop): stop running app locking win-unpacked before pack

On Windows a running Hermes.exe keeps an exclusive lock on
release/win-unpacked/Hermes.exe, so electron-builder's pack cannot
replace it and dies with "remove ...\Hermes.exe: Access is denied" /
ERR_ELECTRON_BUILDER_CANNOT_EXECUTE (before-pack hits the same EPERM
cleaning the dir, and the cache-purge retry repeats the failure since
the lock is still held).

Before building the packaged app, terminate any process whose
executable lives inside this build's release/ tree so the rebuild --
including the installer's headless --update rebuild -- can replace the
binary. Scope is narrow (only exes under release/), POSIX is a no-op
(it can unlink a running binary), and the final error now points
Windows users at the running-app cause.

* test(desktop): cover the win-unpacked lock-breaker helper

Verify _stop_desktop_processes_locking_build is a no-op off-Windows,
terminates only processes whose exe lives under release/ (sparing our
own PID and unrelated installs), and short-circuits when no release dir
exists.

floory 15c99b437f fix(cli): set PYTHON env for node-gyp native builds on NixOS (#40690) 
* fix(cli): set PYTHON env for node-gyp native builds on NixOS

node-gyp (triggered by node-pty during npm ci) looks for python3 on
PATH, which fails on NixOS because python3 lives in the nix store and
is not on the system PATH.

Add _nixos_build_env() — a two-tier helper that detects NixOS and:
1. Fast path: hermes venv python3 (~0s)
2. Fallback: nix-shell which python3 (~2-5s)

Wire it into _run_npm_install_deterministic() via a new env= parameter,
then pass it through cmd_gui() and _update_node_dependencies().

Non-NixOS systems: _nixos_build_env() returns None, behavior unchanged.

* fix(cli): merge _nixos_build_env() with os.environ, fix NixOS detection, add explicit return None

- Critical fix: both Tier 1 (venv) and Tier 2 (nix-shell) now return
  {**os.environ, "PYTHON": ...} instead of {"PYTHON": ...} — subprocess.run
  with env= replaces the entire environment, so the old code wiped PATH
  and broke npm/node on NixOS entirely.
- Uses re.search(r"^ID=nixos$", ...) for anchored NixOS detection instead
  of unanchored substring match (could match ID_LIKE=...nixos).
- Removes redundant Path.exists() guard before read_text(); just catches
  OSError (one filesystem read instead of two).
- Adds explicit return None at end of function for type-hint consistency.

Teknium fef04a197e fix(desktop): purge electron cache unconditionally, not via stdlib zipfile gate 
The salvaged detector validated each cached electron-*.zip with
zipfile.testzip() and only purged ones it judged corrupt. But stdlib
zipfile reads from the end-of-central-directory backward, so it silently
tolerates prepended/concatenated junk — which is exactly the corruption
the bug report names ('86257938 extra bytes at beginning or within
zipfile', a partial download resumed into the same file). testzip()
returns clean on those zips, so the self-heal never fired for the
reported failure mode.

Drop the self-rolled validator: on any packaged-build failure, purge the
version's cached zips AND the half-written unpacked dir, then retry once.
@electron/get re-downloads with its own SHASUM verification — the real
source of truth, which catches prepend/concat/truncate alike. An
unrelated failure just costs one clean re-download and fails the same way.

Verified empirically: zipfile.testzip() returns None (clean) on a
prepended-junk zip; the unconditional purge removes it correctly.

Harry Riddle f583c6ebd5 fix(desktop): recover from corrupt cached Electron download on build 
hermes desktop failed on Linux with an ENOENT renaming
release/linux-unpacked/electron -> Hermes. Root cause is a corrupt
cached Electron zip (~/.cache/electron/electron-*.zip): app-builder
unpack-electron extracts a partial tree from the bad zip that is
missing the electron binary, so electron-builder dies on the final
rename. Re-running repeats the broken extraction, leaving the desktop
app permanently unlaunchable until the cache is manually purged.

- Add _electron_download_cache_dirs() + _purge_corrupt_electron_cache()
  to hermes_cli/main.py: validate every electron-*.zip via
  zipfile.testzip() and delete corrupt ones; honor electron_config_cache
  / ELECTRON_CACHE overrides with per-OS defaults.
- Wire purge + single retry into cmd_gui packaged-build failure path so
  a poisoned download self-heals (electron re-downloads clean).
- Add beforePack hook (apps/desktop/scripts/before-pack.cjs) to wipe the
  target unpacked dir before staging, making packaging idempotent across
  interrupted runs. Cross-platform, best-effort.
- Tests: corrupt-zip detector, cmd_gui purge/retry/launch path,
  no-retry-when-clean path, and node --test for the cleanup helper.

ethernet 46e513ef51 fix(desktop): configure Linux Electron sandbox helper 
Electron's chrome-sandbox helper must be root:root 4755 on Linux or the
sandboxed renderer aborts before the desktop app starts. The existing
installer only searched for macOS .app bundles, so a successful Linux
build was reported as missing.

Changes:
- Add _desktop_linux_sandbox_fixup() to hermes_cli/main.py, called
  before launching a packaged desktop app on Linux.
- Use lstat() + S_ISREG check to reject symlinks — chown/chmod on a
  symlink target would set SUID on an arbitrary path.
- Update install.sh to recognize Linux unpacked artifacts and configure
  chrome-sandbox with proper error handling (the original PR silently
  ignored chown/chmod failures).
- Add regression tests: normal fixup flow, symlink rejection, and
  already-configured skip path.

Closes #37529 (rebased, merge conflicts resolved, copilot review
feedback addressed).

ethernet c2050183a5 feat(desktop): content-hash build stamp with --build-only and --force-build flags 
Add a SHA-256 content-hash based build stamp to `hermes desktop` so
unchanged source trees skip the npm install + build step. Uses pathspec
for .gitignore-aware file matching instead of a hardcoded skip-list.

New CLI flags:
- --build-only: run the build but don't launch the app
- --force-build: rebuild even when the stamp matches

`hermes update` now calls `hermes desktop --build-only` so the
desktop app is rebuilt (if needed) as part of the update flow.

16/16 tests passing.

Teknium 92a567db2d fix(ci): regen model catalog + stop gui tests consuming macos-fixup subprocess calls (#36687) 
Two pre-existing failures on main, unrelated to each other:

- test_model_catalog: website/static/api/model-catalog.json was stale vs
  _PROVIDER_MODELS — minimax/minimax-m2.7 was renamed to minimax/minimax-m3
  without regenerating the committed manifest. Ran scripts/build_model_catalog.py.

- test_gui_command: the macOS relaunchable-signing fixup
  (_desktop_macos_relaunchable_fixup) makes two subprocess.run calls (xattr +
  codesign) on darwin before launch. The two darwin GUI tests set
  sys.platform='darwin' and mock subprocess.run with a 2-element side_effect
  (pack + launch), so the fixup's calls drained the iterator -> StopIteration.
  Mock out the fixup in those two tests so the subprocess accounting stays
  focused on pack/launch.

brooklyn! 51c68d4ab1 Add Hermes desktop app (#20059) 
* feat: better composer etc

* docs: add desktop and dashboard run instructions

* fix(desktop): address security scan findings

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

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

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

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

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

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

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

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

Typical usage:

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

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

* ci(desktop): automate desktop releases

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

* feat: file tabs

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

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

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

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

* feat(desktop): add startup and onboarding flow

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

* fix(desktop): gate prompts on provider setup

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

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

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

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

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

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

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

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

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

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

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

* fix(desktop): polish onboarding provider list

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

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

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

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

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

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

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

* refactor(desktop): tighten onboarding store + overlay

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

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

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

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

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

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

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

* refactor(desktop): drop dead boot overlay

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

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

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

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

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

* Add desktop remote gateway settings

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

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

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

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

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

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

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

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

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

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

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

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

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

Files
- apps/desktop/electron/main.cjs:    runtime layout, HERMES_HOME pin,
                                      factory->active sync, marker v4

                                      dependencies; [pty] extra emptied

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* fix(nix): refresh dashboard lockfile hash

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

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

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

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

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

* fix(desktop): expand release artifact names safely

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

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

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

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

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

* fix(nix): build dashboard from package directory

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Two related fixes for Python detection on Windows:

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

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

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

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

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

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

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

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

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

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

* fix(desktop): address PR review titlebar and usage races

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

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

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

* fix(desktop): move power-user views out of sidebar

Keep Cron and Profiles available through lower-prominence chrome entry points so the workspace sidebar stays focused on core chat navigation.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* feat: update cron modals

* Add dedicated GUI log stream for dashboard debugging.

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

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

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

* Log detailed GUI websocket failure metadata.

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

* Default dashboard startup logging to GUI mode.

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

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

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

* add logging to nsis installer

* feat: glass ui pass

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* feat: more ui qa

* fix(desktop): trim sidebar terminal startup spacer

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

* chore: uptick

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

The canonical install flow

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

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

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

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

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

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

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

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

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

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

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

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

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

Specifically:

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

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

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

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

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

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

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

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

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

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

Specifically:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Address Copilot review round 2.

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

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

Address Copilot review round 3.

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

* fix: address Copilot review round 4

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

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

Address Copilot review round 5.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* chore(desktop): bump version to 0.0.1

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

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

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

* fix: fs icon color

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Fix:

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

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

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

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

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

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

Re-architect:

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

Net effect on the Cloud Shadows long thread:

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

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

* perf(desktop): use textContent for trigger precondition

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* feat(desktop): add hermes gui launcher

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

* bump gui version to 0.0.2

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

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

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

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

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

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

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

* fix(tui_gateway): restore _content_display_text helper

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

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

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

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

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

* fix(telegram): import Set for _dm_topic_chat_ids annotation

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

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

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

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

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

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

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

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

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

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

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

The architecture:

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

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

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

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

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

Limitations of this initial version:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Two root causes:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* test update

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

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

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

* test update

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

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

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

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

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

* update test

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

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

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

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

* update test

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* fix(dashboard): honor injected HERMES_DASHBOARD_SESSION_TOKEN

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* fix: tts endpoints

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

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

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

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

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

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

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

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

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

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

* fix(desktop): repair voice dictation on Windows

Voice dictation was broken on Windows in two ways:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* feat(desktop): add toggleToolset RPC binding

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

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

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

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

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

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

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

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

Also removes three stale completed plan docs.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* dummy update

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

Two fixes for the bb/gui→main transition:

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

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

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

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

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

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

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

* docs(desktop): match base repo README style

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

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

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

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

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

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

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