Port the dashboard Channels flow into the Desktop Messaging page:
- Telegram "Quick setup": the Nous pairing service mints a bot; the page shows
the QR / deep link, polls until Telegram confirms, pre-fills the detected
owner id into the allowlist, and applies. The backend writes the token +
allowlist into the scoped profile and restarts the gateway; the page watches
the restart child's exit so a failed restart surfaces instead of a silent
"gateway stopped".
- Restart-needed banner: every credential save / clear / enable toggle keeps a
banner with "Restart now" up until a restart actually completes. Toasts
vanish; the credential still only loads on the next gateway start.
- runGatewayRestart now resolves a boolean (never rejected before, so the
Webhooks page's catch path was dead and its banner cleared on failure).
- New API helpers carry the page's profile scope on every pairing call so
start/status/apply hit the same backend that holds the pairing in memory.
- i18n keys in all six locales; `qrcode` added to the desktop deps (already
pinned identically in web/).
Add Move up/down controls for actual rooms without changing bot or folder
ordering. Preserve default pin/activity ordering until an explicit move,
retain hidden room slots, and persist Desktop-local order through room
updates, mirror merges, and hydration. No membership or routing writes.
Adapted narrowly from the group ordering idea in archived
NousResearch/Hermes-Bot-Mode#105 by @onuraycicek; rename already exists.

One conflict: upstream 6e7c7c7da9 replaced bot-mode-closed-chat-stays-closed.spec.ts with bot-mode-row-click-mirrors-registry.spec.ts while our side had rewired its mock-server import. Kept upstream's replacement and rewired the three new specs importing ./mock-server to the consolidated tests-js copy (symbols verified present).
Refs #86443
assert-root-install.mjs exists to turn an incomplete root install into one
actionable line instead of a failure deep inside the build. It only ever
checked that vite resolved, so an install covering part of the workspace
graph passed the guard and died later on something else. That is the shape
reported in #86443: the updater's npm install brought in 521 of the 769
packages a full install gives, root node_modules had vite but not katex, and
the build failed on an unresolved katex/dist/katex.min.css with nothing
pointing at the install as the cause. apps/desktop/src/styles.css imports
that stylesheet, so katex is as load-bearing for the renderer bundle as vite
is, and electron / electron-builder are the same for packaging.
Check all four and name every missing one, so a partial install is reported
once and completely rather than one package per build attempt.
Resolution walks node_modules upward the way Node's own lookup does, rather
than going through require.resolve: a package whose exports map does not
expose ./package.json is not resolvable by path even when correctly
installed, and that must not read as missing. It also keeps a dependency
that landed in the app workspace instead of the hoisted root passing.
The guard now runs from prebuild, ahead of npm run clean, so a tree that
cannot build is rejected before the build deletes its own outputs. On this
checkout clean removes build/electron-types and the tsbuildinfo files, not
release/, so this ordering is not by itself what saves a packaged app; it is
the narrow correctness point that a doomed build should not destroy anything
first. build keeps its own call for anyone invoking the build steps directly,
and the check is pure filesystem lookups, so running it twice costs nothing.
The check is extracted as a pure checkRootInstall() returning {ok, error},
matching assert-dist-built.mjs, so it is unit testable without spawning a
process.
Conflicts, three, resolved:
- scripts/desktop-update.ps1: upstream's side taken whole. Upstream moved
the hand-off to scripts/desktop-update/windows.ps1 (this file is now a
one-line compat forwarder) and the new implementation already drains
both pipes asynchronously with bounded abandonment, which supersedes
this branch's stderr-drain fix for the same deadlock.
- apps/desktop/e2e/fixtures.ts: kept upstream's resolveElectronBinary
import alongside this branch's consolidated mock-server path.
- tests-js/scripts/mock-server.ts: kept upstream's task-panel trigger
addition inside the consolidated file; rewired the five upstream specs
still importing './mock-server' to the consolidated path (export sets
verified identical) and dropped the superseded apps/desktop/e2e copy.
The locked dependency tree now carries @babel/* 8.x, which requires
node ^22.18.0 || >=24.11.0. Our engines.node arm said ^24.0.0 and the
installer gates (node_satisfies_build / Test-NodeVersionOk) accepted any
Node 24 — so a system Node 24.0–24.10 cleared every gate we own and then
failed 'npm install' with EBADENGINE under engine-strict=true.
- Raise the 24 arm to ^24.11.0 in root + desktop package.json and the
package-lock.json mirrors
- Tighten node_satisfies_build (install.sh) and Test-NodeVersionOk
(install.ps1) to 24.11+; update user-facing wording
- Add invariant tests: every engines.node arm floor must satisfy every
locked dependency's engines.node, and the installer gates must encode
the same floors as the manifest — so the next babel-style floor bump
turns into a CI red instead of a user install outage
- docs: correct stale 'Node.js v22' provisioning claim
The old harness sliced source text out of plugin.js, re-evaluated the
fragments through vm.runInNewContext, and in a good number of files simply
regex-matched the source for a symbol name. Nothing it asserted survived the
split into modules, and its blind spot was load-bearing: the /new guard
regex-matched clean for as long as it shipped dead.
These are the same contracts driven against the real modules through the real
imports, colocated beside the code they cover. Files whose only content was a
source regex or a re-implementation of the function under test are dropped
rather than translated.
The Hermes Desktop renderer initializes Chromium's audio stack on user
gesture (completion chimes via Web Audio API in completion-sound.ts,
voice TTS via voice-playback.ts, mic capture via use-mic-recorder.ts,
and an eager AudioContext prime in haptics-provider.tsx). On macOS 26+,
that initialization registers the helper with the MediaLibrary TCC
service (kTCCServiceMediaLibrary), which surfaces to the user as a
"Hermes wants to access Music" permission prompt even though Hermes
never reads or writes the Apple Music library.
The Info.plist (built from apps/desktop/package.json's build.mac.extendInfo)
already declares NSAudioCaptureUsageDescription and
NSMicrophoneUsageDescription, but NSAppleMusicUsageDescription was missing
from the desktop app entirely. macOS therefore shows a system-default or
generic prompt for the MediaLibrary bucket instead of an honest description
from the app.
Fix
---
Add NSAppleMusicUsageDescription to build.mac.extendInfo with copy that
disclaims Music library access while explaining the system audio stack
uses voice, TTS, and completion sounds.
Add tests/test_desktop_mac_entitlements.py to pin every NS*UsageDescription
key declared in the Desktop build config. The test:
- parametrized over a (key, required_substring, reason) table
- asserts no leading/trailing whitespace and no newline chars in any usage
string (electron-builder passes them through verbatim; control chars
render as broken prompt text)
- asserts drift-protection: a new NS*UsageDescription key added to the
build config without a matching test row causes a hard failure

Related, not in this PR
-----------------------
- PR #62601 (sounddevice on macOS) is the gateway/CLI side of the same
kTCCServiceMediaLibrary trigger.
- PR #45952 (macOS permission broker foundation) is architectural work
for centralized TCC handling; this fix does not depend on it.
- PR #52839 (browser automation Chrome launch) mutes Chromium audio in
a different surface; the same pattern is recorded there.
Fixes#54551
Since macOS 15 (Sequoia), an app that accesses the local network without
declaring NSLocalNetworkUsageDescription in its Info.plist is denied
silently: no prompt, no entry in System Settings → Privacy & Security →
Local Network, and LAN connections are dropped at the network layer
(manifesting as 'No route to host').
The desktop's build.mac.extendInfo declares camera/microphone/audio
usage descriptions but not the local-network one, so the terminal and
SSH features inside the app could never reach LAN hosts on macOS 15+.
Add the missing declaration.
Without the purpose string, macOS shows a bare Screen Recording
prompt when the desktop app (or a plugin driving desktopCapturer /
ScreenCaptureKit) first requests screen access, and some flows deny
silently instead of prompting.
Verified: package.json parses (python json.load).
Every Linux lane that does real work ran on a 4-core `ubuntu-latest`. The
Python suite and the JS checks were split into many small jobs to make that
size usable. Each split job repeated the full setup. In most of the JS jobs
the repeated setup cost more than the work.
The work lanes move to larger runners. Then the splits that existed only to
make small runners usable go away.
Python tests: 12 slices become 1 job on a 96-core runner. Slicing cost a
matrix job, a duration cache, a per-slice artifact and a merge job. 96 cores
clear the floor that the slowest single test file sets, which is about 82s. A
second slice divides work that is already at that floor, and adds a second
setup. Duration data from run 32522943054 gives the numbers behind this: 3178
files, 11645s in series.
The worker count is explicit, because `run_tests.sh` defaults to twice the
core count. A later commit sets it from a measurement on this hardware.
JS checks: 14 jobs become 1. The matrix paid about 371s of repeated setup to
spread about 612s of work. One larger runner installs one time. The three UI
shard scripts and `run-ui-shard.mjs` are therefore removed, because the
unsharded `test:ui` covers the same tests.
The unit of parallel work inside that job is a CHECK, and not a workspace.
apps/desktop is most of the payload, and its own `check` is a serial && chain.
A spread across workspaces alone therefore leaves that chain as the long pole.
A package that declares `check:*` sub-scripts gives one unit for each
sub-script. That is the same selection rule the matrix used.
The loop lives in `.github/scripts/run-workspace-checks.mjs`, so the same
sequence runs on a laptop. It runs 11 units together, buffers the output of
each one, and fails at the end with the full list. Children that share one
stdout interleave their lines and make a failure hard to read.
`npm run --ws check` stops at the first workspace that fails.
`check:test:plugins` joins the desktop `check` script. The matrix prefers
`check:*` sub-scripts over the plain `check` script, so `check:test:plugins`
ran only as its own leg. Without this change the merge drops that suite and
the job stays green.
node_modules is cached on the lockfile, and `npm ci` is skipped on an exact
hit. The `cache: npm` option of `setup-node` caches only the ~/.npm tarball
cache, which leaves the extract and the postinstalls to pay again.
The arm64 image build stays on a native arm64 runner. A build of linux/arm64
on an x64 host uses emulation.
The docker test lane caps its workers at the core count. Each of those tests
drives a container, so the docker daemon sets the limit and not the processor.
`.github/actionlint.yaml` declares the runner labels. actionlint knows the
GitHub-hosted labels only, and an undeclared label reads as an error that
hides the real findings.
The `detect` job checks out one file through a sparse checkout, and its
timeout drops to 1 minute. It reads
`scripts/ci/classify_changes.py` and nothing else.
Verification:
- actionlint reports 9 findings across all workflows. An unmodified HEAD with
the same config reports the same 9. This change adds none.
- A wrong label still fails. actionlint reports `ubuntu-latest-32-cor` and
`ubuntu-latest-32-arm-cores`.
- Every changed workflow parses, and `name` parses as a string.
- A replay of the `save-durations` merge step against a three-artifact layout
returns all 3178 entries.
- An expansion of the npm script graph gives the same leaf commands for the
parallel units and for a plain `npm run check`, in both directions. Against
the 13-leg matrix the count is 13 to 11, and the whole difference is the
three UI shards that collapse into one unsharded `check:test:ui`.
- `--list` reports the 11 units, and a full local run completes and reports
the time of each unit.
- The runner labels cannot be verified here. The first real run is the test.
Wire babel-plugin-react-compiler through @vitejs/plugin-react v6's
reactCompilerPreset + @rolldown/plugin-babel in the web and desktop
vite configs, scoped to modules that can actually contain components
or hooks (JSX syntax or a react-ish import — the preset's default
filter babel-parsed every TS module). Both vitest configs run compiled
components, so rules-of-react violations fail in CI.
Also fixes the latent bug the compiler exposed: usePluginI18n kept a
stable translator identity over a mutating locale registry, so
memoized consumers (React.memo today, compiled components tomorrow)
served stale strings after a late bundle registration. The registry
version now keys the translator identity — correct with or without
the compiler.
nanostores 1.4.0-1.4.1 annotate batch() @__NO_SIDE_EFFECTS__. Rollup
(via vite build) honors that and erases a result-unused batch(...) call
as dead code -- callback included. Since d57f94a33/053eb7aab/4e520f085
moved the gateway-switch publication (activate() +
+ ) inside batch(), packaged desktop builds lost the entire
publication: clicking a profile in the rail did nothing at all.
Dev builds and vitest run unminified, so only the packaged app broke.
nanostores 1.4.2 removes the annotation from batch() (it stays on the
creation functions, where it is correct). Bump all three pinned copies
(apps/desktop, apps/bootstrap-installer, ui-tui) and add a regression
test asserting the installed nanostores never re-annotates batch.
Pure-ESM, MIT, ~5KB gzipped, no runtime deps. Excluded from optimizeDeps:
it only enters the graph through a dynamic import, so letting the scanner
discover it at first use prebundles the ?raw IIFE as a module (breaking the
raw-text transform) and forces a mid-session page reload.
blobatar 0.2.0 -> 2.0.0 (gen2). Ten silhouettes instead of six:
capsule, triangle, hexagon and droplet join round, organic, boxy,
nub, cloud and sun. BLOB_KIND_TRAIT repinned to gen2 band centers
(empirically verified against the published package: every pinned
value resolves to its named silhouette across seeds). The avatar
picker derives from BLOB_KINDS, so the new shapes appear there
automatically. Note: gen2 remaps most unpinned seed->face mappings
by design (upstream generation change).
New agents now get a blobatar — a deterministic soft-body face generated
from the bot's name (same name, same face, forever) — as the default
shapes mode, with full manual control:
- Face follows the name live while typing in New Agent
- Randomize re-rolls the seed; Lock face pins the current one so a later
rename can't change it (Unlock returns to name-following)
- Any of the six silhouettes (round/organic/boxy/nub/cloud/sun) can be
pinned via frozen-per-major trait positions while the rest stays
name-derived
- Classic geometric shapes remain one click away, and existing bots keep
their stored looks untouched
Wiring: blobatar@0.2.0 (zero deps, ~3.7KB) exported through the plugin
SDK (blobatarSvg / Blobatar), feature-detected in plugin.js with a
legacy-shape fallback for older desktops. Blob shape strings are
'blobatar[:seed[:kind]]' inside the existing meta.shape field, so
persistence, cross-machine ui_meta sync, and the roster's PNG backfill
(data-bot-face tag preserved) all work unchanged.
Adopts the Hermes-Bot-Mode desktop plugin (NousResearch/Hermes-Bot-Mode)
into apps/desktop/src/plugins/hermes-bots/, registered by the bundled
vite glob and ON by default. It stays a pure @hermes/plugin-sdk consumer
in plain-ESM plugin.js form; users disable it live in Settings > Plugins.

- contrib/runtime-loader.ts: a disk/runtime copy of an id that ships
bundled is skipped (standalone installs predating adoption cannot
double-register)
- package.json: check:test:plugins runs the plugin's node:test suite in
CI (138 tests)

With a GH_TOKEN/GITHUB_TOKEN in the environment, electron-builder auto-selects
the github provider and resolves owner/repo from the repository field, falling
back to reading <projectDir>/.git/config. projectDir is apps/desktop, which has
no .git of its own, and app-builder-lib does not walk up to the workspace root
-- so resolution returned null and threw "Cannot detect repository by
.git/config".
On Linux this fires from onAfterPack for a plain `dir` target: the darwin and
Windows branches return early for non-installer targets, Linux has no such
guard. That is why the same build worked elsewhere.
--publish never keeps `pack` from reaching this at all, but `dist:*` and
test-desktop.mjs still resolve publish config on a machine with a token, so
declare the field too.
Tests call the real app-builder-lib resolver rather than asserting on the text
of package.json, so they track electron-builder's behavior instead of our
formatting.

`hermes desktop` runs `npm run pack` through _npm_lifecycle_env(), which
sets CI=1. electron-builder 26 reads that as an implicit publish request
(`onTagOrDraft`) when --publish is absent, so a local --dir build enters
publish resolution it has no business being in.
Pin `--publish never` on the pack script. This is also what electron-builder
asks for directly -- the implicit CI behavior is removed in v27.

The desktop journal synchronously read, parsed, cloned, and rewrote one
aggregate localStorage value while streamed turns were repainting. Large
tool results and multi-session state could therefore block the renderer and
leave the app unresponsive, while the existing macOS diagnostic path lacked
a real native hide/restore regression check.
Store bounded recovery projections under per-session keys, migrate legacy v1
data once, isolate quota and storage failures, and preserve the newest
recoverable tail without allowing oversized writes to replace valid state.
Add a real Electron/CDP macOS-arm64 A/B harness with native visibility control,
renderer heartbeat and Settings/composer/transcript checks, plus focused
regressions. Keep bulk tool payloads, diagnostics, and the existing recovery
merge behavior out of the hot path.
Fixes#63047
Closes the silent-skip hole reviewers flagged: with the index/count
hardcoded in three sibling strings, a copy-paste slip (shard-2of3 running
--shard=1/3) or a partial 3->4 migration would silently skip a third of
the 428-file suite while CI stays green.
scripts/run-ui-shard.mjs parses N/M from npm_lifecycle_event (the script
NAME is the single source of truth), validates the package's shard family
is exactly 1..M for one M, and delegates through 'npm run test:ui' so the
vitest command stays single-sourced.
Mutation-verified: shard-9of3 name -> exit 1 'index out of range';
adding shard-4of4 beside the 3-family -> exit 1 'must form exactly 1..M';
correct invocation runs shard 2/3 (142 files) identically to before.
Review finding (reuse): every other check:* script in this file delegates
to its base script, keeping the runner command defined once. The shard
scripts inlined 'vitest run --project ui' three times, so a later change
to test:ui (flags, project rename) would silently drift from what CI runs.
Route them through 'npm run test:ui -- --shard=N/3' instead (npm forwards
post---- args).
Verified: npm run check:test:ui:shard-1of3 passes (142 files) with
identical file distribution.
The apps/desktop check:test:ui job is the slowest required check
(~5m40s wall; vitest self-report: tests 101s, environment 345s,
import 302s). With 425 isolated jsdom test files, per-file env boot
and module-graph re-import dominate — the tests themselves are ~100s.
Replace the single check:test:ui script with three check:test:ui:shard-NofM
scripts using vitest's built-in --shard. The workspace-discovery matrix in
js-tests.yml already fans out every check:* script as its own job, so no
workflow changes are needed.
Measured locally (8-core, same suite):
unsharded 234s
shard 1/3 + 2/3 + 3/3 70s / 80s / 73s (141+141+141 files, all pass)
Projected CI gate path: ~5m42s -> ~2m20s per shard in parallel.
--no-isolate was evaluated and rejected: 3.5x faster but 103 test files
(533 tests) fail without isolation. pool=threads was a wash; vmThreads
was slower. The local 'npm run check' aggregate now calls test:ui
directly (identical unsharded behavior as before).
`hermes update` was pruning root-level Node dependencies (agent-browser)
because npm ci always wipes and reifies node_modules according to its
active filter -- no root-first/workspace-first ordering or flag
combination (--workspaces=false, --include-workspace-root, etc.) can
reliably keep a root-only package.json dependency from being pruned by
a subsequent workspace-scoped npm ci. Confirmed empirically and via
npm/cli source (isArboristCmd hardcodes includeWorkspaceRoot=false for
ci/install), so no amount of install-order juggling fixes this for good.
Instead of chasing install order, remove the root-only dependencies
that made the npm step fragile in the first place:
- agent-browser is no longer a root package.json dependency. It
resolves lazily via `npx agent-browser` (tools/browser_tool.py
already had this as a fallback; it's now the primary path).
warm_agent_browser_npx_cache() is called fire-and-forget from both
`hermes update` and `hermes doctor --fix` to keep npx's cache warm,
preserving the "available before any session starts" property
agent-browser had as an eager dependency without re-entangling it
with the npm workspace graph.
- @streamdown/math moves to apps/desktop/package.json, where it's
actually imported (markdown-text.tsx, katex-memo.ts) -- it was
never used anywhere else and was subject to the same pruning risk.
- _update_node_dependencies() collapses to a single
`npm ci --workspace ui-tui --workspace web` call now that root has
no dependencies of its own to protect, and keeps its original spot
ahead of `_build_web_ui()` at both call sites in update_cmd.py --
with no root-only dependencies left to protect, there's no reason
for the Node refresh and the web build to run in any particular
order relative to each other.
- hermes_cli/tools_config.py's post-setup Chromium-install path and
hermes_cli/doctor.py's agent-browser check both now resolve through
the same PATH -> Homebrew/Hermes-managed-node -> npx cascade
(_find_agent_browser / _resolve_npx_bin) instead of hand-rolling
their own node_modules/.bin lookups, so they can't diverge from what
browser tools actually invoke at runtime.
- tests-js/package-json-lazy-deps.test.ts gets a lockfile-level check
mirroring the existing camofox one, so a future regression that
reintroduces agent-browser into package-lock.json fails this test
directly instead of relying on manual review to catch it.
Fixes#43564.
The dev:mock script duplicated the e2e mock server. The copy had only
the plain chat reply; every scripted path lived only in the e2e version.
A single mock server now lives in tests-js/scripts/mock-server.ts.
The e2e suite imports it as a library. Running the file directly
starts the server, writes a mock config, and launches the desktop app.
The dev:mock script now runs that file.
The e2e tsconfig lists tests-js/scripts in its include, because the
composite project rule requires every imported file to be listed.
gille's round-2 review: the terminal lifecycle claimed outcomes the
launch hadn't delivered yet.
- posix finish() reorders: outcome -> durable result+marker -> LAUNCH
WITH ACCEPTANCE -> terminal event. mac acceptance is open's exit code
(launchd rejects broken bundles loudly); linux verifies the setsid
child is still alive 1.5s after spawn, so an instant exec failure
downgrades to a held 'manual' state + truthful result instead of a
vanished 'done'. Gated skew/manual outcomes publish a real 'manual'
event (new third shim state -- still zero logic in the page).
- Renderer-free linux recovery: when no chromium-family browser exists,
manual/error outcomes fire notify-send/zenity/kdialog best-effort so a
gated non-relaunch is never a silent disappearance.
- windows.ps1 mirrors the contract: Start-DesktopRelaunch returns
verified acceptance (WMI pid alive / fallback process alive; dying
before the window appears counts as failure), and the finally block
downgrades to Show-ManualFinale + rewritten result when the launch
didn't land. Error path still relaunches after showing itself.
- repro.sh launch / npm run update:repro:launch: real-orchestrator
matrix for instant-exit relaunch downgrade and skew-message surfacing.
- posix.sh cds into the install root before hermes update (found by the
sandboxed behind-repro: parts of the update resolve the mutated tree
from cwd, which is the Desktop's cwd -- it updated the DEVELOPER'S
checkout while reporting success against the sandbox).
Address helix4u's review:
- finish() now delivers the outcome BEFORE publishing it: mac bundle swap
and the linux relaunch gate run first, then the result file, marker
removal, and the shim event -- the app launch itself goes last so it
can't race the result write. A gated/skewed linux install (AppImage/
deb/rpm, broken sandbox helper) surfaces its message in the result file
AND holds the shim window open with it instead of closing on a false
'Opening Hermes...'.
- mac swap is transactional with a checked rollback; a failed install
restores the previous bundle and the result says so (exit 7 when even
rollback fails). Failed 'open' rewrites the result truthfully.
- linux gate is an exact port of the deleted update-relaunch.ts logic:
anchored path-segment match on <root>/apps/desktop/release/linux-unpacked,
chrome-sandbox absent = namespace build = fine, present = root+setuid
required, with the real opt-outs (ELECTRON_DISABLE_SANDBOX, --no-sandbox
among replayed args, or the Desktop vouching) instead of the invented
HERMES_DESKTOP_NO_SANDBOX. collectRelaunchArgs/sandboxFallbackFromEnv
live in updater-process.ts again; the Desktop passes filtered launch
args (after --) and --relaunch-cwd so a deep-link or --no-sandbox
launch survives the update.
- result/status JSON strings are escaped (git permits '"' in branch
names) and the result write is atomic (tmp + rename).
- coverage: resolvePosixScriptHandoff + ported helpers in
updater-process.test.ts (19 pass); repro.sh gate / npm run
update:repro:gate asserts the whole gate matrix and round-trips a
hostile branch name through the result JSON.
scripts/desktop-update/repro.sh drives the real code paths against a
disposable HERMES_HOME under /tmp: shim/shim-fail (UI dry runs), fresh
(literal install.sh), behind N (rewound checkout driven forward by the
orchestrator), error (broken venv -> abort + result file). Exposed as
npm run update:shim / update:shim:fail / update:repro:* from
apps/desktop.
Reverts the Electron portion of 7537de9e74 (40.10.2 -> 40.10.6,
GHSA-r4w5-6pfg-jxp5). The bump broke fresh Windows installs: 40.10.3+
swapped install.js's extraction to @electron-internal/extract-zip, an
MSVC-built native binding that ERR_DLOPEN_FAILEDs on machines without
the VC++ Redistributable (field report Aug 9, fresh VM, confirmed).
Security impact of reverting is nil for our code paths:
- GHSA-r4w5-6pfg-jxp5 (Moderate 5.9): requires the legacy
ProtocolResponse.url API with session-partition isolation; desktop
only uses the modern protocol.handle() and no cross-session
isolation. Not exposed.
- GHSA-9f4c-93c8-jc8g (High 7.2): affects ALL of 40.x with no fixed
40.x release (fix is 41.10.3+); 40.10.2 vs 40.10.6 is a wash. Real
mitigation is hardening our setWindowOpenHandler (follow-up PR).
allowScripts version-keyed entry moved to electron@40.10.2 so the
postinstall (dist download) still runs; allow-scripts-sync vitest
suite passes. Electron 41.x major remains deferred/on hold.
get-windows@9.3.0 (MIT, zero runtime deps on macOS/Linux) is external to the
esbuild bundle and staged into dist/node_modules per target platform: the
universal Swift helper on macOS, the prebuilt N-API binding on Windows
(fail-closed magic-byte validation), nothing on Linux (xprop at runtime).
The staged lib/windows.js is rewritten to load the binding directly so
@mapbox/node-pre-gyp's tree stays out of the package.
`hermes desktop` still failed with EBADENGINE demanding Node >=26 after
#76562, on a machine whose `apps/desktop/package.json` already said
`^20.19.0 || >=22.12.0`. #76562 fixed the manifest but not its mirror in
`package-lock.json`, and `npm ci` reads engines from the lockfile:
package.json apps/desktop -> {'node': '^20.19.0 || >=22.12.0'}
package-lock apps/desktop -> {'node': '>=26.0.0'} <- what gated
Chasing that exposed a second, pre-existing problem: the floor #76562
declared was too generous. Running the real `npm ci` against the whole
workspace on Node 22.21.1 fails on a transitive dependency —
npm error notsup Not compatible with your version of node/npm:
react-router@8.3.0
npm error notsup Required: {"node":">=22.22.0"}
react-router 8.3.0 (a direct dependency of both `apps/desktop` and `web`)
declares `>=22.22.0`, which is tighter than Vite's `^20.19 || >=22.12` and
excludes all of Node 20. So `>=20.0.0` promised support the tree cannot
deliver: an install on Node 20 or early 22 passed the installer's gate and
then died inside `npm ci` on someone else's package.
All four engine declarations now state the floor the dependency tree
actually has, `>=22.22.0`: root `package.json`, `apps/desktop/package.json`,
and both of their `package-lock.json` mirrors. The installer gates move with
them (`node_satisfies_build` in install.sh, `Test-NodeVersionOk` in
install.ps1) so a too-old system Node is replaced with the managed one
*before* npm runs, and the failure a user does see names hermes-agent rather
than a transitive package. NODE_VERSION stays 22 — latest-v22.x is 22.23.2,
comfortably above the floor.
The invariant test gains the case that would have caught the mirror drift on
its own: the desktop assertion now pins the tightest floor a dependency
actually declares, and the managed-runtime check compares majors, since
install.sh fetches latest-v{major}.x rather than {major}.0.0.
Verified with real `npm ci --dry-run` over the full workspace:
- node 22.23.2 (what install.sh provisions) -> 1258 packages
- node 26.5.1 -> 1189 packages
- node 22.21.1 (below the floor) -> EBADENGINE naming
hermes-agent, i.e. our own manifest, not react-router
Fresh installs and `hermes update` both fail at the first `npm ci`:
npm error code EBADENGINE
npm error notsup Required: {"node":">=26.0.0","npm":">=12.0.0"}
npm error notsup Actual: {"node":"v24.15.0","npm":"11.12.1"}
`.npmrc` sets engine-strict=true, so `engines` is a hard gate on every
install. The floor was raised to npm >=12 — but no Node release bundles
npm 12: Node 26 ships 11.17.0, 24 ships 11.16.0, 22 ships 10.9.8. The
requirement is unsatisfiable by any stock toolchain, so the installer
provisions a Node and is immediately unable to install with it.
engines.npm becomes `<11.10.0 || >=11.17.0`. That still excludes the band
the strictness was actually for: npm 11.10-11.16 honor `min-release-age`
but ignore `min-release-age-exclude`, both set in .npmrc, so they apply the
14-day gate to packages we exempted. Verified rather than assumed — npm
11.12.1 fails `ETARGET ... vite@8.2.0 with a date before 7/18/2026` while
11.17.0 installs it.
engines.node returns to >=20.0.0 and the toolchain floor to Node 22.
Nothing in the tree needs 26: Vite 8.2.0 declares `^20.19.0 || >=22.12.0`
and Electron 40 declares `>=12.20.55`. Requiring 26 force-migrated every
working install for no dependency reason. apps/desktop drops to Vite's own
floor for the same reason; the desktop bundle builds clean on Node 22.
install.sh gained a second gate: a system Node was accepted on version
alone, so a machine with Node 24 + its bundled npm 11.16.0 (the bad band)
passed the check and then failed `npm ci`. npm_supports_npmrc() now rejects
that band and installs the managed Node instead.
CI, Docker and nix are hermetic and keep pinning Node 26 / npm 12 — they
provision their own toolchain, and both satisfy the relaxed range.
tests/test_engines_satisfiable.py encodes the invariants that would have
caught this: the npm floor must be met by an npm some shipping Node
bundles, the node floor by the runtime install.sh provisions, the desktop
floor by its own build toolchain, and the lockfile mirror must match.
Restoring the broken values fails 5 of them with the reason stated.
Verified end-to-end (real downloads, temp HERMES_HOME):
- fresh install: managed node v22.23.2 / npm 10.9.8 -> npm ci, 209 packages
- existing managed tree (v22.22.3 / npm 10.9.8) -> npm ci, 209 packages
- node 26.5.1 + bundled npm 11.17.0 -> npm ci, 208 packages
- system npm 11.12.1 (the reported case) -> EBADENGINE, recovery provisions
a managed tree and retries green
- apps/desktop `npm run build` on Node 22 -> dist built, assert passes
Hermes now pins its toolchain to Node 26 everywhere. Every path that
installs, accepts, heals, or upgrades a Node runtime moves from the old
22-default / `^20.19 || >=22.12` floor to a single rule: Node >=26.
Installers:
- scripts/install.sh — NODE_VERSION=26; node_satisfies_build() collapses
the two-branch Vite floor to `major >= 26`; user-facing messages updated.
- scripts/install.ps1 — $NodeVersion=26; Test-NodeVersionOk likewise;
winget fallback switches OpenJS.NodeJS.LTS -> OpenJS.NodeJS (26 is
Current, not LTS — the LTS manifest would reinstall a too-old Node).
- Dockerfile — node_source stage node:22-bookworm-slim -> node:26 (digest
pinned, amd64 sha256:9e6f...bf73).
- nix/ was already on nodejs_26 (lib.nix, npm-12-0-2.nix); the checks.nix
wrapper check ratchets from `>= 20` to `>= 26`.
Heal/upgrade paths:
- scripts/lib/node-bootstrap.sh — HERMES_NODE_TARGET_MAJOR default 22->26
and HERMES_NODE_MIN_VERSION default 20->26, so heal_managed_node,
_nb_install_bundled_node, and the fnm/proto/nvm/brew rungs all target 26
and stop accepting an on-PATH Node below it. Both remain env-overridable.
- hermes_constants.py — _HERMES_NODE_TARGET_MAJOR fallback 22->26, which
drives the Windows heal path's latest-v26.x download.
Version gates:
- package.json engines.node >=20 -> >=26; apps/desktop engines
`^20.19.0 || >=22.12.0` -> `>=26.0.0`.
- CI setup-node: all five workflows 22 -> 26.
- Docs describing Hermes's own toolchain updated (windows-native, docker,
acp, nix-setup, contributing). Skill docs describing third-party tools'
own requirements are untouched.
Termux still installs via `pkg install nodejs` best-effort (nodejs.org
ships no Android tarballs); that path was never version-gated.
Verified: bash -n on both shell scripts, PowerShell AST parse of
install.ps1, latest-v26.x index resolves (node-v26.5.1), and the install
test suite — 18 tests across the 5 install/runtime test files — passes.
Twenty-odd desktop files import `@assistant-ui/core` directly, but it was
never in `dependencies` — it resolved only because react 0.15 pulled core
0.3.2 and npm hoisted it to the workspace root. react 0.14.24 wants core
^0.2.19, which nests under `react/node_modules`, so the undeclared imports
stop resolving and the build fails on `@assistant-ui/core/internal`.
Declare it so resolution doesn't depend on hoisting luck either way.
The 0.15 bump rode along with the npm audit pass in #75037, but it was
not required by any advisory — `npm audit` reports 0 vulnerabilities with
0.14.24 pinned. It is a breaking major that costs us a working transcript,
so take the API stability instead.
