A hardened-runtime build needs the camera entitlement and an
NSCameraUsageDescription string, or the packaged app is killed on first
camera access instead of prompting.
The session permission hooks were written for the voice composer and denied
video outright, so any renderer getUserMedia({video}) failed with
NotAllowedError before the OS was ever consulted.
Rename isAudioCapturePermission to isMediaCapturePermission and accept video
alongside audio in both the request and check handlers. The OS capture
permission still applies, so the user keeps a real allow/deny.
The grant_spent notice fired for every subscription user with top-up
funds the moment their cap was reached and camped in the CLI/TUI status
bar and desktop toasts with no action to take — the account keeps
working off top-up. Remove it everywhere:
- agent/credits_tracker.py: drop grant_cond + the emit/clear block;
the dev fixture state now (correctly) produces no notice
- TUI: keep the turn-start clear of credits.grant_spent as back-compat
for older backends that still emit the key
- Desktop: drop the demo step and stale comment references
- Docs/config comments: remove grant-spent from credits_notices text
- Tests updated: policy/cold-start now assert the key never fires
Usage bands, depleted, and restored notices are unchanged; /usage still
reports the full balance breakdown.
The prior commit made save_config_value resolve its target via
get_hermes_home() (live env) instead of the import-time cli._hermes_home
constant. Two _persist_model_switch tests patched only cli._hermes_home
and wrote/read tmp_path/config.yaml, so the write now landed in the real
HERMES_HOME and the readback saw stale values. Set HERMES_HOME=tmp_path
(kept the _hermes_home patch for belt-and-suspenders). No production
change.
Responds to hermes-sweeper review on #54717: existing tests only mocked
platform_registry.get(). Add a hermetic fake deferred-loader test that
runs real PlatformRegistry resolution → PluginContext.register_cli_command
→ argparse subparser/choices visibility, without Photon SDK imports.
Closes#54678
`hermes photon ...` could fail with argparse `invalid choice: 'photon'`
even when the bundled Photon platform plugin is present. Photon registers
its top-level CLI command from the platform adapter module via
`ctx.register_cli_command(name="photon", ...)`, but bundled platform
plugins are cheap-registered as *deferred* entries to avoid importing every
gateway SDK during normal startup.
On the unknown-top-level-command slow path, `discover_plugins()` records the
deferred loader but never imports the matching platform module, so the CLI
registration side effect doesn't run and `photon` stays absent from
`_cli_commands` — argparse then rejects it.
Fix: after `discover_plugins()` on that slow path, resolve only the deferred
platform whose name matches the first positional token (via
`platform_registry.get(name)`) before reading `_cli_commands`. This imports
exactly the targeted platform, leaving normal startup cheap (a bare `hermes`
or flags-only invocation has no positional token and touches nothing). The
resolution is best-effort: registry/import failures are logged at debug and
never crash startup.
Added 3 tests in tests/hermes_cli/test_startup_plugin_gating.py: resolves the
matching platform, ignores empty/None command, and swallows registry errors.
Fails without the fix (symbol absent).
- Extract the cmdk filter into exported rankSearchOption and cover it,
SearchableSelect selection/clear/placeholder, and ConfigField
searchable-schema routing with 12 vitest cases (sabotage-verified:
the backend schema test fails on unfixed main).
- Add searchPlaceholder/noResults/systemDefault strings to ja/ar/zh-hant
(zh + en came with the salvaged commits; defineLocale would have
fallen back to English otherwise).
- Add a backend invariant test: timezone ships as a searchable,
clearable select of sorted IANA ids with a UTC fallback.
- Add 'System default' clear option to SearchableSelect via clearLabel prop
- Add clearable flag to ConfigFieldSchema (schema-driven, not hardcoded)
- Add clearable: true to timezone schema override in web_server.py
- Fix CommandItem value for clear item: use clearLabel instead of '' so
cmdk can match it during search
- Fix backend: or ['UTC'] fallback for hosts without tzdata where
available_timezones() returns an empty set (not an exception)
- Add systemDefault i18n key (en, types, zh)
- Fix focus: use autoFocus on CommandInput instead of e.preventDefault()
- Fix filter: prioritize city segment match (return 2 for slash match)
- Fix handleSelect: always select, don't toggle-deselect
- Add aria-haspopup to trigger button
- Use defensive placeholder logic
The timezone field was a free-text input with no guidance on format.
Users had to know the exact IANA identifier (e.g. America/New_York)
to configure it. Replace it with a searchable combobox built on
Popover + cmdk Command — the same stack as Shadcn's Combobox.
Backend:
- Add `_timezone_options()` to web_server.py (cached at import time,
returns sorted zoneinfo.available_timezones() — ~598 identifiers)
- Add `"timezone"` to `_SCHEMA_OVERRIDES` with `type: "select"`,
`options`, and `searchable: true`
Frontend:
- New `SearchableSelect` component (Popover + cmdk Command)
— closed-world filterable dropdown for large option lists
- `ConfigField` routes to `SearchableSelect` when
`schema.searchable === true` (explicit opt-in, no threshold)
- Add `searchable?: boolean` to `ConfigFieldSchema` type
- Add i18n keys: `searchPlaceholder`, `noResults`
The `searchable` flag is deterministic — no existing field is
affected unless explicitly opted in. Future large-list fields
can adopt the same pattern by adding `searchable: true` to their
schema override.
The wake-word ear reverted to disabled after every restart even when
closed enabled. Root cause is general, not wake-specific: save_config_value
followed load_cli_config's precedence, which falls back to the repo's
checked-in cli-config.yaml when HERMES_HOME/config.yaml doesn't exist yet.
On such installs (managed/desktop first launch), the toggle's persist wrote
wake_word.enabled=true into cli-config.yaml and returned success — but
every config reader (load_config -> get_hermes_home()/config.yaml,
including load_wake_word_config) reads only HERMES_HOME/config.yaml, so the
setting was invisible on the next launch. Same silent loss hit any runtime
persist (model switch, /reasoning, /fast, skin) on a config-less install.
save_config_value now always targets get_hermes_home()/config.yaml,
creating it if absent, and never writes the shipped repo template. Also
resolves HERMES_HOME live instead of the import-time _hermes_home constant
(profile-safe).
E2E verified: persist -> fresh module reload -> load_wake_word_config sees
enabled=true and wake_surface_enabled('gui') is True, for both a fresh
(no config.yaml) and an existing-config install.
- cli.py save_config_value: target user config, create if absent
- tests: 2 regression tests (creates user config when absent; never writes
repo cli-config.yaml); fixture now sets HERMES_HOME. 11 file + 206
adjacent config/model-switch tests green
The cap is shared across CLI, desktop/TUI and the messaging gateway, so the
surface that gets rejected is rarely the one holding the slots. The rejection
read "Hermes is at the active session limit (5/5). Try again when another
session finishes." while every slot was an idle desktop tab, which took
filesystem access to work out.
Name the holders in the message, and show slot usage plus each holder in
`hermes status`. Both are inert when max_concurrent_sessions is unset, which
is the default. The gateway's duplicate copy of the message now reuses the
shared helper.
An open chat window took a session-cap slot at session.create/resume time.
Every desktop tile paint and every background reconnect-resume opens one, so
on a websocket-flappy host they accumulated: five parked desktop tabs filled a
5-slot cap and locked the messaging gateway (which shares the cap) out for
fourteen minutes while running no agents at all.
A slot held that way is invisible everywhere. An unprompted draft has no DB row
and the sidebar filters it out with min_messages=1, so the only way to diagnose
it was reading runtime/active_sessions.json by hand.
Claim on the first turn instead, mirroring the lazy contract
_ensure_session_db_row already uses for the row itself. Capacity now means an
agent can run rather than that a window exists, and anything holding a slot is
something the user can see.
Also reclaim leases whose session skipped teardown. _prune_dead only fires when
the owning pid dies, and a dashboard/serve backend runs for days, so a leaked
lease was held until restart. The owning process reconciles against the leases
it still holds, which is exact and needs no heartbeat write on the turn path.
- openrouter + nous curated lists: replace google/gemini-3-pro-preview with

Saying 'stop' in a voice chat did nothing — the transcript was just
submitted to the agent as a normal turn, so the conversation never ended.
The only way out was the mouse/hotkey. That's not how a hands-free voice
assistant should work.
useVoiceConversation now checks each finished utterance against a spoken
stop-command matcher BEFORE submitting: 'stop', 'stop listening', 'never
mind', 'goodbye', 'cancel', 'that's all', etc., optionally addressed
('hey hermes, stop'). A match ends the conversation (flips enabled=false,
which drives the existing end() teardown — mic close, playback stop, wake
re-arm) instead of sending a turn.
Deliberately conservative: only a WHOLE-utterance stop phrase matches, so
substantive requests that merely contain 'stop' ('stop the docker
container', 'how do I stop a process') still go through.
- apps/desktop/src/lib/voice-stop-word.ts: isVoiceStopCommand() matcher
- use-voice-conversation.ts: onStopWord option + intercept before submit
- use-composer-voice.ts: wire onStopWord -> end the conversation
- 6 matcher tests (bare/multi-word/addressed stop; substantive requests
with 'stop' pass through; bare address words don't match)
- docs: note the spoken-stop behavior
'hey hor' triggered the wake word: the default sensitivity was 0.5, which
for openWakeWord IS the raw per-frame score threshold — openWakeWord's own
permissive baseline that near-misses clear. Raised the default to 0.6 so
phonetic near-misses fall short while real 'hey hermes' (typically 0.9+)
still fires easily.
Also fixed a real cross-engine inconsistency found while checking: the
sensitivity knob is documented 'higher = stricter' and behaves that way
for openWakeWord (threshold = sensitivity) and sherpa (0.05 + 0.4*s), but
Porcupine's own 'sensitivities' param runs the opposite way (higher = MORE
false alarms, per Picovoice). Turning sensitivity up made Porcupine looser
— backwards. Now inverted (1 - sensitivity) so 'higher = stricter' holds
for every engine.
- tools/wake_word.py: default 0.6; _sensitivity fallback uses _DEFAULTS;
Porcupine sensitivity inverted with rationale
- hermes_cli/config.py + docs: default + consistent-direction note
- tests: Porcupine inversion, default>=0.6 regression, fallback-to-default
A short, bright, rising two-note ding (G5 -> C6) plays the moment 'Hey
Hermes' is detected, before voice capture starts, so it's obvious the
wake registered. Deliberately distinct from the turn-end completion cue
(that one settles; this one rises = 'listening'). Reuses the same
lightweight WebAudio synthesis as completion-sound.ts — no asset to ship
— and is gated by the shared sound-mute toggle ($hapticsMuted), so
muting turn-end sounds silences it too.
- apps/desktop/src/lib/wake-sound.ts: playWakeSound()
- wiring.tsx: fire it at the top of the wake.detected handler
- 3 tests (plays two-note chime, silent when muted, never throws with
no WebAudio)
The rebase's lock was produced by uv 0.9.28 (runtime venv); CI runs uv
0.11.33, whose resolver rejected it (uv sync --locked failed). Relocked
with 0.11.33 — only wake-extra deps and their transitives added, no
unrelated version churn.
- Route _get_read_conn through _connect_tracked_db so per-thread
read-only connections are registered with the POSIX lock-safety
guard (connect_tracked), matching the writer and existing read-only
paths. Without this, byte-level probes of state.db could close() an
fd that cancels locks held by an untracked read connection.
- Convert _search_unindexed_gap, _run_trigram_search, CJK-bigram FTS
search, and get_meta to _read_ctx — these are pure SELECT queries
called from search_messages that were still taking self._lock,
defeating the PR's contention fix for those paths.
- Add @pytest.mark.requires_wal to the 5 tests that assume WAL is
active. Hermes disables WAL on SQLite < 3.51.3 (WAL-reset bug),
so these tests fail on the venv's SQLite 3.46.0 without the marker.
- Remove unused 'time' import.
The gateway shares ONE SessionDB across every agent, so every recall/browse
read (session_search discover/scroll/browse, memory prefetch, title resolve)
queued behind every writer flush on self._lock — one Python lock in front of
a WAL database that natively supports concurrent readers. Measured convoy:
a 0.23s FTS query stretched to 112s and a browse flush to 137s while 6-8
concurrent turns flushed hundreds of tool results.
Fix: under WAL, read-only methods (get_session, resolve_session_by_title,
list_sessions_rich, get_messages, get_messages_around, get_anchored_view,
search_messages) run on a per-thread mode=ro connection via _read_ctx(),
taking no lock at all. Fresh read transactions begin per statement, so
read-your-committed-writes holds for flush-then-search patterns. Non-WAL
(NFS DELETE fallback) or read-conn open failure keeps the legacy locked
single-connection path, remembered per thread to avoid per-query retries.
openWakeWord scores one ~80ms frame at a time and the detector fired the
instant a SINGLE frame crossed threshold — so a stray phoneme in background
conversation could trigger the wake word unintentionally (reported in
testing). A real utterance of the phrase holds a high score across several
consecutive frames; an ambient blip spikes just one.
_OpenWakeWordEngine now requires N consecutive over-threshold frames
(wake_word.confirmation_frames, default 3) before firing. The streak resets
on any sub-threshold frame and on engine reset() (pause/resume), so a
pre-pause frame can't count toward a post-resume fire. confirmation_frames=1
restores the old single-frame behavior; clamped 1..10.
Only openWakeWord is affected — sherpa (streaming transducer) and porcupine
decode the whole phrase internally and already reject single-frame spikes.
- tools/wake_word.py: _confirmation_frames() accessor, streak logic in
process()/reset(), config default
- hermes_cli/config.py: wake_word.confirmation_frames documented default
- tests: 5 new (spike rejected, sustained fires once, =1 legacy behavior,
reset clears streak, config clamp) — 58 wake tests green
- docs: 'Reducing false triggers on ambient speech' section
Follow-up to benbarclay's macOS ARM64 tflite fix:
- test_openwakeword_bundled_model_matches_framework stubs
ensure_tflite_runtime()=True so it exercises artifact selection, not
runtime availability — off-Darwin the bridge legitimately returns
False and the engine falls back to onnx (that path is covered by its
own tests). Was failing on Linux CI otherwise.
- check_wake_word_requirements now ANDs both this branch's STT/TTS gate
and Ben's tflite_ok into 'available' (cherry-pick conflict resolution).
openWakeWord's ONNX backend returns near-zero scores on Apple Silicon
(dscripka/openWakeWord#336), so "Hey Hermes" never crossed the 0.5
threshold: the listener armed, the microphone worked, and nothing fired.
Bisecting the pipeline puts the fault in exactly one stage — feeding the
same audio through both backends, the melspectrogram front-end is
bit-identical (maxdiff 0.00000) and the wake classifier agrees on
identical features, while the shared embedding model diverges by 45.44.
Cross-feeding confirms it: tflite features scored through the *onnx*
classifier give 0.9948 vs 0.000009 for onnx features. A telling
secondary symptom is that scores fall as input gets louder (0.5x ->
0.00031, 8x -> 0.000066), which is garbage inference rather than a weak
detection.
Selecting tflite in config alone does not fix it. openWakeWord hardcodes
`import tflite_runtime.interpreter` but declares tflite-runtime for
`platform_system == "Linux"` only; on macOS the equivalent wheel is
ai-edge-litert, so that import always fails and model.py silently
downgrades back to onnx. The result is a detector that reports itself
listening and can never fire.
- default the backend per platform (tflite on macOS ARM64, onnx
elsewhere) instead of hardcoding onnx, and pick the matching bundled
model artifact
- bridge tflite_runtime -> ai_edge_litert through sys.modules, in-process,
with no writes to site-packages
- refuse the silent onnx downgrade on macOS ARM64 and report the missing
runtime through check_wake_word_requirements() so the GUI surfaces an
actionable hint rather than arming a dead ear
- lazy-install ai-edge-litert via its own feature key, because lazy-dep
specs cannot carry PEP 508 markers (_spec_is_safe rejects ";")
An explicit `inference_framework` in config still wins, so anyone pinning
a backend keeps it.
Verified on macOS 26.5.2 / M-series: "hey hermes" scores 0.0005 on onnx
and 0.9423 on tflite from the same clip, with cross-phrase controls at
0.0003. Live over-the-air through the real microphone fires 4/4
utterances (peak 0.9532).
Teknium: the ear must always be visible so a user can click to enable
passive listening. If it can't start (missing STT/TTS, deps still
installing, no mic permission), the click surfaces the reason in the
tooltip and the toggle stays off — but the control never disappears.
Removes the 'if (!wake.available && !wake.enabled) return null' hide
branch that made the button vanish on machines where a requirements
probe returned false (the Windows report). The only non-idle state is
paused-for-voice (disabled, in the voice-chat pill), since an active
voice conversation genuinely holds the mic.
Tests updated: 'stays visible when unavailable and not enabled' and
'surfaces the refusal reason in the tooltip, still visible' replace the
old hide assertion. 30 vitest green, tsc + eslint clean.
test_install_ps1_is_pure_ascii guards against PowerShell 5.1 ANSI
codepage misdecoding (issues #66994/#67000); the Install-DesktopVoiceDeps
comment had an em-dash.
Two fixes from live testing (Teknium):
1. Desktop installs now ship the wake/voice stacks up front.
install.sh + install.ps1 desktop stages run 'uv pip install
-e .[wake,voice]' (best-effort, lazy-install remains the fallback)
before building the app, so the first ear-click arms instantly
instead of sitting through a multi-minute onnxruntime download.
CLI-only installs keep the lazy path — [all] curation unchanged.
2. The vanished ear: the STT/TTS gate made wake.status call
check_tts_requirements(), whose edge path runs _import_edge_tts →
lazy_deps.ensure — a synchronous PIP INSTALL inside a status poll.
On a venv without edge-tts that blew the desktop's 30s RPC timeout,
armWakeWord caught the error, the atom never learned enabled=true,
and the ear unmounted. _tts_ready is now a pure probe: deps missing
+ lazy installs allowed counts as ready (installs at first speak)
WITHOUT touching pip; check_tts_requirements only runs once deps
are present. Regression test asserts the probe never calls it while
deps are missing.
The ear vanished whenever a voice conversation ran (the ConversationPill
replaces the whole controls row) and whenever a transient start refusal
marked the feature unavailable — so a persistent, config-backed setting
silently disappeared mid-session. The wake word is passive by design:
it should be visibly listening no matter what the GUI is doing, with
exactly one pause state — an active voice chat holding the mic.
- ConversationPill now renders the ear in paused form (disabled, EarOff,
'paused during voice chat' tooltip) so voice chat shows the listener
yielding the mic instead of the toggle vanishing.
- WakeWordButton hides only when the feature can't run AND isn't enabled
in config; $wakeWord gains 'enabled' (config truth from wake.status /
start/stop responses) so transient 'unavailable' refusals no longer
unmount the button.
- Busy agent turns never touched the listener (it keeps listening
through agent loops; wake.detected already opens a fresh session),
and now they can't hide the toggle either.
- New i18n key wakeWordPausedVoice across en/ja/zh/zh-hant.
Tests: ear mounted during busy turn, mounted through refusal when
config-enabled, hidden when unavailable+disabled, paused ear disabled
inside the pill. 29 vitest green across controls + wake-word store.
The wake loop is wake → record → STT → agent → TTS. Arming without
either end configured gives a mic that hears you and then does nothing
perceivable — a useless experience. check_wake_word_requirements now
probes both (same probes /voice uses: stt.enabled + provider != none;
check_tts_requirements) and refuses with a pointer to `hermes tools`
naming exactly which half is missing. The desktop ear hides (available:
false already hides the button), /wake on prints the hint on CLI/TUI.
wake.start also validates requirements BEFORE persisting
wake_word.enabled, so a refused gesture can't leave config claiming on
while nothing can ever arm.
Tests: per-half and both-missing hint assertions; existing requirements
tests pinned via _voice_loop_ready so they don't depend on the test
venv's installed voice stack. E2E: stt.enabled=false in a real config
-> unavailable with the speech-to-text hint.
Internal testing (macOS): clicking the ear froze the button for ~30s,
then it went blue but 'hey hermes' never fired even though STT worked.
Two distinct bugs:
1. Frozen-then-timeout button: first-use wake.start lazy-installs the
detection engine (onnxruntime is a large wheel), which blows the
desktop's default 30s WS request timeout — the RPC 'failed' client-
side while the backend kept installing and armed later on its own.
wake.start now gets a 180s budget and the pending state says
'arming — first use may take a minute while the engine installs'
instead of a silent disabled button.
2. Armed but deaf: macOS grants mic permission per PROCESS. The
renderer having mic access (STT working) does not grant the Python
backend anything — CoreAudio hands an unentitled process a 'working'
stream that delivers zeros forever, so the listener looks healthy
and can never hear the phrase. The detector now tracks frame peaks:
10s of consecutive near-zero frames sets audio_silent, logged with
the exact macOS Settings path, cleared automatically when audio
appears. Surfaced everywhere: wake.status (audio_silent + hint),
desktop ear tooltip (kept visible while listening), /wake status on
TUI (⚠ line) and classic CLI, plus a docs troubleshooting section.
Tests: detector silent-flag set/recover cycle (fake silent/loud
streams), desktop tooltip keeps the dead-mic hint while listening.
44 wake Python tests, 22 desktop + 14 TUI vitest green.
Ending a voice conversation left the wake word silently off even with
wake_word.enabled: true — the desktop fired one wake.resume and hoped;
if the mic was still held by the just-released WebRTC capture (or the
resume raced teardown), the listener stayed dead until the user
re-toggled it. The wake word is a persistent setting: on is on until
the user explicitly turns it off.
- Desktop: resumeWakeAfterVoice() replaces the fire-and-forget resume —
resume, then verify against wake.status (config 'enabled' is the
authority) and re-arm via wake.start, with spaced retries to ride out
mic-release latency. Passive path: never passes persist, never writes
config; respects an explicit off and another surface's mic lease.
- Backend: wake.status now reports 'enabled' (config truth) so clients
reconcile against the setting, not runtime listener state.
- Backend: _wake_resume_if_owner self-heals — a resume that throws
(mic still busy) retries in a background thread for up to 15s. A
False return (lease gone/moved) is final, never retried, so the
retry can't steal another surface's mic. Covers the TUI/gateway
voice.record path which had no recovery at all (CLI has its idle
watchdog; the gateway had nothing).
- 6 new vitest cases: re-arm on enabled+down, no persist on the passive
path, resume-alone success, disabled stays off, owned lease yields,
older-backend no-op.
The wake-pause effect assigned wakePausedRef.current inside useEffect,
tripping eslint's no-restricted-syntax guard against atom→ref mirroring.
The ref is actually a request token (did WE issue wake.pause?), not a
reactive mirror — moving the assignment into a pauseWakeForVoice
callback keeps the semantics and passes the rule without a disable.
Clicking the desktop ear button or running /wake on|off now writes
wake_word.enabled to config.yaml (live, saved for future sessions), so the
feature no longer requires hand-editing config before the UI toggle works.
- wake.start accepts persist:true (explicit gesture): flips
wake_word.enabled on in config before arming; response reports
enabled_persisted. Passive auto-arm paths (desktop gateway-ready,
TUI reconnect) never pass it, so a mic can't become persistently
enabled without a deliberate user action.
- wake.stop accepts persist:true: writes wake_word.enabled: false so
auto-arm stays off next session; reports disabled_persisted.
- Split the refusal reason: 'disabled' (feature off in config — a
persisted gesture turns it on) vs 'disabled_for_surface' (explicit
wake_word.surface scoping, which persist does NOT override).
- Classic CLI /wake on|off and bare-toggle persist the flag too
(skips the write when config already matches).
- Desktop tooltip now maps refusal codes to friendly text (mirrors
the TUI's START_REASON_TEXT) instead of showing raw codes like
disabled_for_surface.
- Docs: quick-start notes the toggle persists; ear-button mention.
check_wake_word_requirements() gated 'available' on the audio probe,
but the probe imports sounddevice + numpy — two of the packages the
lazy installer would install. On a fresh machine deps_ok was False, so
audio_ok was always False and /wake on printed the manual pip hint and
bailed before the engine constructors' lazy_deps.ensure() could run.
Now the audio probe only runs once deps are installed; with deps
missing and lazy installs allowed (the default), /wake on proceeds and
ensure() installs the pinned engine deps in-process — no restart. The
manual pip hint remains for security.allow_lazy_installs=false, and a
mic hint still blocks when deps are present but no audio device works.
The CLI announces the one-time engine install so the pause is explained.
numpy is a lazy voice-extra dep absent from CI's hermetic env; the two
engine process() tests imported it for real. Stub asarray/float32 in
the fixture (verified against a blocked-numpy import, matching CI).
96-utterance TTS matrix (6 enrolled profile phrases x 4 voices/accents +
4 negative phrases x 4 voices) through the real engine: the old mapping
(default threshold 0.35) missed 3/24 positives; remapping so sensitivity
0.5 lands on sherpa's recommended 0.25 recovers 2 of 3 while keeping
0/16 false fires. Detection 23/24, routing accuracy 23/23.
