Tests (and any older cached NousSubscriptionFeatures) construct the
features dict without an 'stt' key; the .stt property raises KeyError.
Use features.get('stt') instead.
STT previously had no configuration surface outside hand-editing
config.yaml — no category in the hermes tools picker, no provider
matrix in the GUI capabilities tab, no status line in hermes setup.
- TOOL_CATEGORIES['stt']: 7 provider rows (Local Whisper, Nous
Subscription managed, OpenAI, Groq, xAI, ElevenLabs Scribe,
DeepInfra) with key prompts, badges, and post-setup hooks
- stt_provider marker wired through _write_provider_config,
_configure_provider, _reconfigure_provider, and
_is_provider_active — GUI and CLI share one write path
(apply_provider_selection)
- STT model picker (_configure_stt_model + STT_MODEL_CATALOG) runs
after provider pick: local sizes, Groq whisper family, OpenAI
whisper-1/gpt-4o-*/gpt-transcribe, ElevenLabs scribe (model_id key)
- faster_whisper post-setup hook auto-installs the local backend;
registered in _POST_SETUP_READY
- stt is CONFIG-ONLY (_CONFIG_ONLY_TOOLSETS): it ships no tool
schemas, so it is excluded from the per-platform enable checklist;
the GUI toolset toggle writes stt.enabled instead of
platform_toolsets
- hermes setup shows a Speech-to-Text status line per provider
- Mistral row omitted (mistralai PyPI quarantine), mirroring the
dashboard stt.provider options
Tests: tests/hermes_cli/test_stt_picker.py (20 cases) incl. invariant
checks against agent.transcription_registry builtins and the runtime
OPENAI_MODELS/GROQ_MODELS sets.
The dashboard config page had a select for stt.provider (and
stt.elevenlabs.model_id) but the per-provider model fields
(stt.local.model, stt.groq.model, stt.openai.model) rendered as free
text. Register them as selects so the new gpt-transcribe model — and
the existing catalog — are discoverable options in the GUI, matching
the desktop settings enums.
Follow-up on the #53205 salvage: replace bare is_file() probes of the
managed (~/.hermes/node[/bin]) and legacy (node_modules/.bin) locations
with shutil.which(..., path=dir) so Windows resolves the executable
.cmd shim instead of the extensionless POSIX script — the same miss
class fixed for _has_agent_browser() in #73932. Also covers the
Windows managed layout where the binary sits in node/ directly.
`hermes acp --setup-browser` installs agent-browser into the Hermes-managed
node prefix (~/.hermes/node/bin/agent-browser), which isn't necessarily on
PATH. doctor only checked PROJECT_ROOT/node_modules and PATH (shutil.which),
so it false-negatived with "agent-browser not installed" even though the
binary was present and runnable. Mirror dep_ensure._has_hermes_agent_browser()
by also checking HERMES_HOME/node/bin and the legacy
HERMES_HOME/node_modules/.bin path, each gated by agent_browser_runnable().
Tested with tests/hermes_cli/test_doctor.py (added positive + not-runnable
cases) and pytest tests/hermes_cli/test_doctor.py -q (66 passed).
The exact kwargs snapshot broke when VAD hardening added keys — the
test's real contract is 'null stt.local: must not crash or force
language/prompt'. Baseline kwargs are pinned by the dedicated suite.
Local faster-whisper called model.transcribe with bare {'beam_size': 5}:
no VAD, cross-window conditioning on, no confidence filtering. Pure
silence produced hallucinated tokens (E2E: 5s anullsrc WAV -> 'You',
no_speech_prob=0.705) and noisy clips could produce runs of junk, often
in other languages.
Three-layer class fix, one shared owner for every local-whisper call
site (build_local_transcribe_kwargs):
1. Silero VAD filter (bundled with faster-whisper) on by default —
silence never reaches the model. stt.local.vad: false restores the
raw behavior for music/ambient transcription.
stt.local.vad_min_silence_ms tunes chunk splitting (default 500).
2. condition_on_previous_text=False — one hallucinated token can no
longer seed a self-reinforcing run; negligible cost for
voice-note-length audio.
3. Segment confidence gate (_join_confident_segments): drop a segment
only when no_speech_prob > 0.6 AND avg_logprob < -1.0 (openai-whisper's
own heuristic shape; both must hit so quiet-but-real speech survives).
Config: stt.local.no_speech_prob_threshold / logprob_threshold.
The WHISPER_HALLUCINATIONS blocklist in voice_mode.py stays as
last-resort defense but should now almost never fire.
E2E (real faster-whisper 'base', CPU int8):
silence.wav before 'You' -> after ''
noise.wav before '' -> after ''
speech.wav before/after 'Hello World, this is a test of the
transcription system.' (unchanged)
Docs (EN + zh-Hans), DEFAULT_CONFIG, cli-config.yaml.example updated;
19 unit tests (kwargs contract, off-switch, confidence gate incl.
quiet-speech survival, _transcribe_local wiring), sabotage-verified.
Saying OR typing a configured stop phrase (voice.stop_phrases, default
"stop") now ends the voice chat everywhere, not just classic CLI PTT:
- hermes_cli/voice.py: new explicit on_stop_phrase callback through
start_continuous/stop_continuous. The force-transcribe path previously
DISCARDED the stop phrase silently — with auto_restart=False the client
re-arms the next capture, so the conversation never ended. Both halt
paths now fire on_stop_phrase (fallback: on_silent_limit for legacy
callers) as user intent, distinct from the no-speech timeout.
- tui_gateway/server.py: voice.record wires on_stop_phrase and emits
voice.transcript {stop_phrase: true} after flipping HERMES_VOICE(_TTS)
off and stopping streaming TTS — same teardown as /voice off. The TTS
barge-in monitor stop-checks its transcript too. prompt.submit consumes
a TYPED bare stop phrase at the server-side choke point when voice mode
is on (returns {voice_stopped: true}, no turn starts).
- ui-tui: voice.transcript {stop_phrase} ends voice mode with a clear
'voice chat ended' notice (distinct from the no-speech-limit message);
submitPrompt releases the busy latch on a consumed voice_stopped reply.
- cli.py: _typed_voice_stop in process_loop — typing a bare stop phrase
while voice mode/continuous is active ends voice mode instead of
sending 'stop' to the agent; typed 'stop' outside voice mode is
unchanged. Voice transcripts skip the check (already stop-checked).
- desktop: interceptsTypedVoiceStop — the composer's onSubmit ends the
live voice conversation (same path as clicking end on the pill) when a
bare stop command is typed with no attachments; renderer-owned loop, so
handled client-side like the existing spoken isVoiceStopCommand.
- tools/voice_mode.py: transcribe_recording never lets the Whisper
hallucination filter swallow a configured stop phrase (e.g. 'bye'
configured as a stop phrase is both a hallucination-blocklist entry and
a stop phrase — stop-phrase check now wins).
Tests: continuous-loop signal (sabotage-verified), force-transcribe stop
signal + legacy fallback, hallucination-filter ordering, typed-stop CLI
unit tests (voice on/off/longer text), prompt.submit typed-stop gateway
tests, TUI vitest for stop_phrase event handling, desktop vitest for the
typed-stop interceptor.
On Windows, applyUpdates kills its own backend (releaseBackendLock)
BEFORE the venv-blocker preflight but only writes the on-disk update
marker AFTER the scan. Killing the backend drops the renderer's
WebSocket; the renderer reconnects within ~1s and the marker-only
waitForUpdateToFinish gate happily spawns a fresh 'hermes serve' inside
the update's own critical section. scanVenvBlockers then finds that
brand-new process and aborts with 'another Hermes process is using this
installation' — a different PID on every attempt, so Desktop self-update
can never succeed.
Fix: extract the gate into update-gate.ts (pure, DI-testable) and make
it consult BOTH signals — the on-disk marker AND the in-process
updateInFlight flag. The success path writes the marker before the flag
clears in applyUpdates' finally, so there is no instant where both are
false and a waiter can slip through. Also gate spawnPoolBackend, which
previously had no waitForLocalStart at all — a background profile window
could respawn a pool backend during the same window with the identical
abort.
Tests: update-gate.test.ts covers the open gate, the flag-only window
(the #73822 shape), the flag→marker handoff with no gap, and timeout.
Follow-ups on top of #66911's salvaged commit:
- hermes:fs:desktopPluginsRoot now resolves the ACTIVE desktop profile
(readActiveDesktopProfile) so named profiles keep their own
profiles/<name>/desktop-plugins root instead of sharing the global one
(profile-scope concern raised on the PR thread).
- startDirWatch in runtime-loader.ts was a third sibling site still
deriving the watch path from the backend's hermes_home (added by the
later fs-watch commit); routed through the same Electron-local
resolver, with regression coverage.
The Settings "Open plugins folder" action and the runtime disk-plugin
scanner both derived the plugin directory from getStatus().hermes_home.
Against a remote backend that value is a path on the REMOTE box (or
undefined), producing `undefined/desktop-plugins` — the folder action
errors ("Could not open the plugins folder undefined") and disk-plugin
discovery silently finds nothing, even with a valid local plugin.js.
Add an Electron-owned IPC resolver (hermes:fs:desktopPluginsRoot) that
returns <HERMES_HOME>/desktop-plugins computed from the main-process
HERMES_HOME — the local Electron path, valid in every connection mode —
creating it on demand. Route both the Settings folder action and the
runtime scanner through it, so a remote backend never determines the
local filesystem location used for Desktop runtime plugins.
Fixes#66899
Streamed response text carried a 4-space _STREAM_PAD indent and the
final-response Rich Panel used padding=(1, 4), so every line selected
out of the terminal came with leading whitespace. Both now render
flush-left (pad empty, panel padding=(1, 0)); the table-realignment
width budgets were widened to match.
/copy now writes the ORIGINAL message text through native clipboard
tools (pbcopy / PowerShell Set-Clipboard via base64 / wl-copy / xclip /
xsel — same fallback chain as the TUI's writeClipboardText), falling
back to OSC 52 only when no native backend succeeds. This is the
TUI-equivalent answer to soft-wrap mangling: the clipboard gets the raw
text, not the rendered layout.
_has_agent_browser()'s new managed-Node rung calls
shutil.which('agent-browser', path=...); tests that monkeypatch
shutil.which globally with 1-arg lambdas raised TypeError when their
code path reached the browser readiness probe (test_post_setup_gating,
test_setup_model_provider).
Three GUI Capabilities-tab defects reported on Windows:
1. Browser rows stuck on 'Setup required' after a successful setup run.
Root causes, all in the readiness probe (not the installer):
- _has_agent_browser() never searched the Hermes-managed Node dir
(%LOCALAPPDATA%/hermes/node / $HERMES_HOME/node/bin) where the
Windows install lands, and probed node_modules/.bin/agent-browser
as the extensionless POSIX shim, which fails exec on Windows
(WinError 193) — now resolved via PATHEXT-aware shutil.which
against both rungs, mirroring _find_agent_browser().
- Cloud rows (Nous Subscription Browser Use, Browserbase, Browser
Use, Firecrawl) declared post_setup: agent_browser, whose
readiness gate requires a LOCAL Chromium build the cloud never
uses — switched to the cloud-scoped 'browserbase' hook (CLI-only).
- _agent_browser_installed() could read browser_tool's stale cached
'Chromium missing' result from before the install ran in the
spawned post-setup process — cache now dropped before probing so
the pill flips to Ready right after a successful run.
2. No way to tell which backend is active, and clicking a row to read
its details silently rewrote config. Row click now only
expands/collapses; activation is an explicit 'Use this backend'
button, the active row carries an 'Active' pill, and the expanded
active row says 'This is your active backend'.
3. OpenAI TTS showed one model and one voice. The options were always
defined but rendered through a native <datalist>, which filters by
the field's current value — a field already set to a valid option
suggested only itself. Replaced with a real combobox (Input +
dropdown) that lists every option, and voice suggestions now track
the selected model per the OpenAI TTS docs: tts-1/tts-1-hd = 9
voices, gpt-4o-mini-tts = 13 (adds ballad, verse, marin, cedar).
Type-to-focus routes through requestComposerFocus('active'), which resolved
to a module-level activeTarget claim. Inactive tabs stay mounted under
data-pane-hidden, so typing in a session tile then clicking the main tab
left activeTarget on the buried tile: use-keybinds preventDefaults the
keystroke, the buried composer ignores the request (or is filtered out),
and the main composer never sees it. Same class of bug after the inline
edit composer unmounts with activeTarget still 'edit'.
Heal 'active' against the visible data-composer-target stamp (the same
visibility policy as every other document-wide surface lookup), release
the claim on real unmounts (useComposerDraft + user-edit-composer), and
keep getActiveComposer honest so Esc / soft / / voice agree with the
keyboard path.
The unmount release is salvaged from #72625 (@briandevans); this PR adds
the keep-alive tab heal his unmount-only fix couldn't cover.

The Skills Hub 'Marketplace' tab showed a single useless entry: Anthropic
changed .claude-plugin/marketplace.json to bundle-shaped plugins whose
source is './', so all plugins collapsed to one identifier pointing at the
repo root, and the second marketplace repo (aiskillstore/marketplace) is
gone (404). Everything in anthropics/skills is already surfaced by the
GitHub tap as the Anthropic tab, making this source fully redundant.
Removes ClaudeMarketplaceSource and all wiring: source router, index
builder (crawl + floors + sort order + rate-limit messaging), extract
labels/install/URL mapping, hub UI tab, web server labels, CLI limits,
docs (en + zh), the legacy index-cache snapshot, and test fixtures.
Stale skills-index entries with source 'claude-marketplace' still install
fine: HermesIndexSource fetches via resolved GitHub paths generically.
Replace 20 lines of manual os.open/O_EXCL/fdopen/fsync/os.replace with the

control, and owner preservation. The only novel helper (_fsync_directory)
is retained — atomic_json_write does not do directory fsync.
Update test_flush_write_failure_leaves_no_recovery_file to monkeypatch
utils.os.replace (the new call path) instead of gateway.shutdown_flush.os.replace.

LINE plugin.yaml plus line/wecom-callback/msgraph-webhook/
whatsapp-cloud/teams user-guide pages still documented the old
IPv4-only 0.0.0.0 defaults; update to the dual-stack unset default.
Telegram webhook env docs live in the adapter docstring (updated with
the code change); its plugin.yaml has no webhook host entry.
Same class of bug as the LINE adapter (NS-603): defaulting the webhook
bind to "0.0.0.0" (or hardcoding it) binds IPv4 ONLY, so the listener
is unreachable over IPv6-only private networks such as Fly.io 6PN.
- wecom callback_adapter: DEFAULT_HOST None; config.py env seed no
longer forces 0.0.0.0 when WECOM_CALLBACK_HOST is unset.
- msgraph_webhook: DEFAULT_HOST None; the allowed_source_cidrs
requirement still fires for the all-interfaces default (host=None is
treated as network-accessible).
- whatsapp_cloud: DEFAULT_WEBHOOK_HOST None.
- teams: hardcoded 0.0.0.0 TCPSite bind → _DEFAULT_HOST=None with new
TEAMS_HOST / extra.host override (mirrors LINE_HOST pattern).
- telegram: hardcoded listen="0.0.0.0" → default "" (tornado
bind_sockets opens one socket per address family; verified against
PTB 22.6/tornado) with new TELEGRAM_WEBHOOK_HOST / extra.webhook_host
override.
Explicit host overrides everywhere are preserved; empty/unset collapses
to the dual-stack default. "::" remains a bad substitute on
bindv6only=1 hosts (see LINE adapter comment).
test_default_bind_serves_both_families asserts an IPv6 listening socket
exists, which is the environment's capability, not the adapter's — CI
runners with IPv6 disabled would flake. Probe an actual ::1 bind (not
just socket.has_ipv6, a compile-time constant) and skip cleanly when
the host has no usable IPv6 stack.
The LINE adapter's webhook server defaulted to host="0.0.0.0", which
binds IPv4 ONLY. On IPv6-only private networks — notably Fly.io 6PN,
where the hosted edge router reverse-proxies LINE ingest to
<app>.internal:8646 over an fdaa: IPv6 address — nothing is listening
on the dialed address: connection refused → customer-visible 502 when
LINE's console verifies the webhook (NS-603).
This is the same bug the generic webhook adapter fixed in d542894ad;
the LINE adapter was never updated to match. Fix mirrors that commit:
- DEFAULT_HOST = None → asyncio/aiohttp create_server binds one socket
per address family (v4 + v6), regardless of the bindv6only sysctl.
"::" is NOT a valid substitute — Fly machines set bindv6only=1, so
it would yield an IPv6-only socket and break IPv4 loopback probes.
- Empty-string host collapses to None; LINE_HOST/extra.host still pin
a specific bind address.
- reuse_address=False scoped to macOS only (BSD wildcard-socket
traffic-splitting footgun), mirroring 9420ad946.
- The three outbound-media guards compared webhook_host == "0.0.0.0"
by string equality; extracted to _missing_public_url() which treats
None/0.0.0.0/::/"" as "no fetchable hostname" so the LINE_PUBLIC_URL
requirement still fires under the new default. _media_url() falls
back to 127.0.0.1 instead of interpolating 'None' into URLs.
Tests: dual-stack default decision table (default None, empty→None,
pinned preserved, LINE_HOST override), behavioural both-families bind
proof via runner.addresses, and the media public-URL guard matrix.
88 passed, ruff clean.
Companion router fix (hermes-agent-router) routes /webhooks/line and
/line/webhook|/line/media to :8646 over 6PN; both are needed for
end-to-end hosted LINE delivery.
Fixes NS-603
show_status now reads get_nous_auth_status_local(); the test_status.py
mocks still patched the old live-resolve entry point, so the patched
dict was never consumed (CI slice 8/8 red on the salvage PR).
Follow-up widening of the /api/status fix: add get_nous_auth_status_local(),
a refresh-free auth-store snapshot (local invoke-JWT decode only), and use it
on the read-only display surfaces that previously called
get_nous_auth_status() -> resolve_nous_runtime_credentials() -> live OAuth
refresh POST:
- hermes_cli/status.py (hermes status auth-provider panel)
- hermes_cli/doctor.py (hermes doctor auth-provider checks)
- hermes_cli/portal_cli.py (hermes portal status display)
- hermes_cli/web_server.py /api/portal endpoint and the accounts-tab
provider card dispatcher (_resolve_provider_status nous branch)
Action paths (login flows, portal operations needing a live credential)
keep using get_nous_auth_status(). Part of NS-592.
resolve_sidecar_dir() probes the filesystem (touch/unlink) and can mirror
sidecar files to HERMES_HOME. Doing that as a module-import side effect
meant plugin discovery, `hermes --help`, and test collection all paid a
filesystem probe (and possibly a mirror copy) just for importing the
photon adapter or CLI.
Convert _SIDECAR_DIR/_NPM_ERROR_LOG in adapter.py and cli.py to lazy
cached accessors (_sidecar_dir()/_npm_error_log()); resolution now
happens on first actual use. Existing tests that monkeypatch the
_SIDECAR_DIR module global keep working — the accessors honor a
non-None value. Adds a regression test proving import performs no
resolution.
The Photon iMessage sidecar needs node_modules under
plugins/platforms/photon/sidecar/, but hosted/managed images keep the
whole install tree under an immutable /opt/hermes — every install and
self-heal path (setup CLI, stale-deps reinstall, cold install) died on
EROFS, and hosted users have no shell to work around it.
Three-layer fix, mirroring the WhatsApp bridge resolver pattern:
1. Bake the deps into the image. The Dockerfile now runs npm ci for the
sidecar in the layer-cached dependency stage (deterministic installs
from the committed lockfile; the postinstall spectrum-ts patch runs
at build time). Hosted happy path needs no runtime install at all.
2. New sidecar_paths.resolve_sidecar_dir() decides where the sidecar
runs from: PHOTON_SIDECAR_DIR override > writable source dir (dev
installs, unchanged) > read-only dir with baked fresh deps (managed
image) > mirror to $HERMES_HOME/photon/sidecar (writable data
volume) when deps are missing or stale in a read-only tree. The
mirror refreshes changed source files on image updates while
keeping node_modules, so the existing lockfile-staleness self-heal
works there.
3. connect() can now cold-install: _start_sidecar() runs the bounded
npm ci bootstrap when node_modules is missing instead of raising
immediately, and check_requirements() reports available when a
self-install is possible (npm present + writable resolved dir) so
the gateway actually creates the adapter on hosted instances. A
failed bootstrap still raises the actionable error, which connect()
surfaces as the retryable SIDECAR_FAILED fatal state on the
dashboard.
Tests: resolver decision table (env override, in-place, mirror,
refresh, fail-open), cold-install lifecycle paths, and a Dockerfile
contract test guarding the baked-deps + no-chown invariants.
Fixes NS-606.
The ownership guard let a sentinel with pid=None pass as self-owned, so
an exiting life could clobber evidence of unknown provenance with a
clean-exit claim. Tighten: only rewrite when the sentinel pid matches
os.getpid() exactly; pid=None (or malformed) is left untouched. Adds
tests for the pid=None no-op and the own-pid rewrite paths.
scripts/check-windows-footguns.py (blocking CI lint) rightly flagged the
os.kill(pid, 0) liveness probe: on Windows sig=0 collides with
CTRL_C_EVENT and GenerateConsoleCtrlEvent hard-kills the target's whole
console group (bpo-14484) — a forensics module must never be able to
kill the process it's checking on. Route through gateway.status._pid_exists,
the repo's canonical psutil-backed no-kill probe.
Hosted agents that die uncleanly (kernel OOM kill, SIGKILL, whole-VM
death) leave no trace: shutdown_forensics only covers graceful signals,
gateway-exit-diag.log only covers exit paths that actually run, and the
VM reboot wipes dmesg before anyone can capture it. NS-608 (BlueAtlas
hourly crash cycle, July 12-15) took days of manual log correlation to
classify because nothing recorded 'the previous life ended violently'.
Add gateway/lifecycle_ledger.py — a sentinel state machine persisted to
<HERMES_HOME>/state/gateway.lifecycle.json:
- start_gateway() claims the sentinel (phase=running) right after the
PID-file/runtime-lock claim, and reports any prior life that never
reached an exit path as gateway.previous_unclean_exit in
gateway-exit-diag.log + a WARNING log line.
- Every exit funnel marks the sentinel exited with a reason:
_exit_after_graceful_shutdown (graceful_shutdown), the shutdown
watchdog (shutdown_watchdog), and the loop-liveness watchdog
(loop_liveness_watchdog).
- Ownership-guarded for --replace takeovers: a live matching owner is
never reported dead, and the old life cannot clobber the
replacement's freshly claimed sentinel on its way out.
The 30s loop heartbeat now embeds a cheap /proc memory sample (own RSS,
MemAvailable, swap used) so every unclean-death report carries a
'memory N seconds before death' snapshot; the detector flags
suspected_oom when the last sample shows <64MiB or <5% available.
container-boot.log lines gain prior_exit=clean|unclean|unknown per
profile, stamping unclean container deaths into the volume-persisted
boot log where support can grep for them.
Tests: tests/gateway/test_lifecycle_ledger.py (16 cases) + 4 new
container-boot annotation cases. Existing watchdog/forensics/boot
suites all green; ruff clean.
Adds gpt-transcribe (OpenAI's new file-transcription model, $0.0045/min)
to the OpenAI STT provider:
- OPENAI_MODELS set: gpt-transcribe is recognized so provider
auto-correction keeps it on OpenAI and rejects it on Groq
- Language hint wiring: gpt-transcribe replaces the singular
'language' field with a 'languages' list; the API rejects the legacy
field, so the hint is sent via extra_body {languages: [..]}
- Config comment (DEFAULT_CONFIG), cli-config.yaml.example, desktop
settings enum, and docs (en + zh-Hans) updated
- Tests: model pass-through, languages-list hint shape, legacy singular
hint preserved for gpt-4o-transcribe, Groq auto-correction
gpt-live-transcribe (realtime WebSocket, $0.017/min) is NOT wired here:
the file-based STT pipeline has no realtime session path; it belongs in
a future realtime/voice-mode integration.
_install_dependencies now routes through tools.lazy_deps.install_specs
(NS-605); the force-reinstall test still stubbed
hermes_cli.tools_config._pip_install, so its spy list stayed empty
(CI slice 3/8 red on the salvage PR).
Widen NS-605 to the two remaining direct-install sites in the hindsight
plugin, which still shelled out to 'uv pip install --python
sys.executable' and therefore failed (EROFS/EACCES) on immutable hosted
images with sealed venvs, and lost packages on redeploy:
- post_setup dependency install (~L835): install_specs() with ok /
blocked-reason / stderr handling matching honcho/mem0.
- initialize()-time hindsight-client auto-upgrade (~L1240):
install_specs(); blocked installs log the gate reason with the manual
command instead of a raw subprocess error, and init proceeds.
Audited every other memory plugin (supermemory, byterover, holographic,
openviking, retaindb) for direct pip/uv install subprocess calls: none
remain — their deps flow through plugin.yaml pip_dependencies or
lazy_deps.ensure().
Tests: TestClientAutoUpgradeRoutesThroughLazyDeps — upgrade goes through
install_specs with the exact spec (regression guard asserts no
subprocess.run), blocked upgrade is non-fatal and surfaces the gate
reason. Updated TestPostSetupEnvEncoding stubs to the new install path.
Installing a memory provider (Honcho, mem0, hindsight, ...) from the
dashboard Plugins page failed on hosted deployments with a permission
error: the setup endpoint shelled out to
`uv pip install --python sys.executable`, which targets the sealed
read-only venv under /opt/hermes (immutable hosted image, NS-579/#49113).
The correct mechanism already exists: tools/lazy_deps.py redirects
installs to the writable durable target on the data volume
(HERMES_LAZY_INSTALL_TARGET=/opt/data/lazy-packages) when the venv is
sealed (HERMES_DISABLE_LAZY_INSTALLS=1), appends the target to the END
of sys.path (core venv always wins collisions), and constrains shared
deps to core-venv versions. The dashboard installer simply never used
it.
Fix:
- tools/lazy_deps.py: new public install_specs() — installs arbitrary
manifest-declared pip specs through the same environment routing as
ensure(): venv-scoped by default, durable-target on sealed images,
refused with an actionable reason when gated off (config kill switch
or sealed venv without a target — never surfaces raw EROFS/EACCES).
Specs are validated with _spec_is_safe(); post-install it invalidates
import/metadata caches so availability rechecks in the same process
see the new packages without a restart. Never raises.
- hermes_cli/web_server.py: _install_memory_provider_pip_dependencies
now calls install_specs() instead of building its own uv/pip
subprocess. Blocked installs surface the gate reason in the setup
results; the response's status block reflects post-install
availability (stale 'missing deps' state clears immediately).
- hermes_cli/memory_setup.py, plugins/memory/honcho/cli.py,
plugins/memory/mem0/_setup.py: CLI setup wizards routed through
install_specs() too — same sealed-venv failure mode, same fix.
No hosted setup path writes to /opt/hermes anymore; provider discovery
and installation now use the same environment (sys.path activation is
shared with the lazy-install bootstrap in hermes_bootstrap).
Tests:
- tests/tools/test_lazy_deps.py: TestInstallSpecs — gating matrix
(sealed+no-target blocked with immutable-deployment reason, config
kill switch, sealed+target proceeds), spec-safety rejection before
any subprocess, venv-scoped vs --target command display, failure
stderr passthrough, never-raises contract.
- tests/hermes_cli/test_web_server.py: setup endpoint routes pip
through lazy_deps (regression guard asserts no direct 'pip install'
subprocess), blocked-reason surfacing, same-response availability
recheck clears stale missing state.
Fixes NS-605 (Plain T-1111).
speak_text (hermes_cli/voice.py — the TUI/gateway one-shot TTS entry
point) now checks resolve_streaming_provider() first: when the
configured provider has a chunked streamer, the reply is spoken through
the same stream_tts_to_speaker pipeline CLI voice mode uses, so audio
starts on sentence one instead of after whole-file synthesis. No
streamer (edge/piper/etc.) or a streaming failure falls back to the
existing whole-file path unchanged — one dispatcher, zero parallel
streaming implementations.

Follow-up integration for the #47588 salvage, aligning the new streamers
with the post-campaign invariants:
- All streaming key lookups go through _resolve_key -> tts_tool.
_resolve_provider_key -> resolve_provider_secret (config > env/.env >
credential pool, profile-scoped) — never bare get_env_value. xAI
resolves via resolve_xai_http_credentials so OAuth users stream too.
- _capped(): every provider's chunk iterator is bounded at 16 MiB per
sentence, mirroring _read_tts_response_bytes' bounded-upstream-body
invariant on the sync paths.
- Tests updated for the resolver contract + new coverage for credential
routing and the cap.
