UpdateMarkerGuard::acquire overwrote the in-progress marker
unconditionally, so a Tauri update launched while a dashboard-spawned
"hermes update" was mid-flight simply took the marker and ran a second
updater over the same checkout. That is the race behind the reported
Windows failure: install-mode bootstrap rewound the tree while the
dashboard's updater was still running npm install against it.
acquire now returns Result and refuses when a live foreign owner holds
the marker, and Drop no longer deletes a marker this process does not
own. Liveness matches the Python and Electron readers of the same file:
dead pid or past the shared age ceiling means stale and reclaimable, so
a crashed updater cannot wedge future updates.
Adds a cfg(unix) libc dependency for the signal-0 liveness probe; the
Windows path uses OpenProcess/GetExitCodeProcess.
Three surfaces start updates against one checkout: a terminal
"hermes update", the dashboard's Update button (which spawns that same
command detached), and the desktop's, which hands off to the Tauri
updater. Only the Tauri updater published the in-progress marker, and
only Electron read it -- to gate backend startup, not to stop a second
updater. So a dashboard-spawned update and an installer-driven git
checkout could mutate the same tree concurrently, rewriting source under
a live interpreter.
Claim the same marker from cmd_update rather than adding a second
mechanism: same path, same pid+started_at payload the Rust and Electron
readers already parse. A marker only counts as live when its pid is alive
and it is inside the shared age ceiling, so a crashed updater self-heals
instead of wedging every future update. Release only removes a marker we
still own, leaving a handoff partner's claim intact.
Refusing exits 2, matching the existing concurrent-instance contract the
Tauri updater already recognizes.
hermes-setup.exe bakes its build-time commit into the binary
(BUILD_PIN_COMMIT) and passes it as -Commit on every install-mode run,
including the retry the desktop's "Update didn't finish" screen kicks
off. The repository stage checked that SHA out unconditionally, so an
installer built months earlier rewound a current managed checkout to its
build commit -- 9,160 commits in the reported case -- leaving ancient
source against a current venv. npm then failed on workspaces that did not
exist yet at that commit, and every later update ran against the wrong
tree.
Skip the pin when its target is already an ancestor of HEAD. Fresh clones
have no such ancestry so reproducible/CI pinning is unchanged, and
--force-commit / -ForceCommit still rolls back on purpose.
- Remove tests/-shadowing sys.path.insert(dirname/'..') from 11 test files:
it prepended the tests/ dir itself to sys.path, so 'import agent' /
'import hermes_cli' resolved to the test packages and collection died
with ModuleNotFoundError depending on import order (2 files failed in
every full-suite run; 9 more were latent).
- Patch call_llm in 5 context-compressor tests that called compress()
unmocked: each burned ~50s attempting live LLM traffic through the
relay before falling back (572s file — the slowest in the suite, and
flaky under the 300s per-file timeout). File now runs in ~5s.
- agent/redact.py: fix two catastrophically-backtracking regexes hit by
the compressor's redaction pass on large payloads —
_STRICT_URL_USERINFO_RE anchors on the mandatory '//' (optional-scheme
prefix backtracked O(n^2): ~55s on a 320KB payload, now sub-ms;
output-equivalence fuzz-verified on 20k random strings), and the
_CFG_DOTTED_RE/_CFG_ANCHORED_RE subs gain an exact linear keyword
pre-gate so secret-free text skips the quadratic pattern entirely.
- tests/gateway/test_feishu.py: version-guard the extra_ua_tags SDK
signature check; the repo pins lark-oapi==1.6.8 but stale local
installs (1.5.3) fail the assertion — skip below the pin.
- tests/tools/test_managed_browserbase_and_modal.py: stub
agent.redact + agent.credential_persistence in the fake agent package
(empty __path__ blocks all real agent.* imports added since the fake
was written).
- tests/gateway/test_startup_restart_race.py: raise wait_for timeouts
2s -> 30s; 2s wall-clock on a loaded 40-worker box flaked in the
baseline run (passes instantly when the box is quiet).
Follow-up to the salvaged #62026 ownership fix, folding in #72054's
CancelledError rule by @adurham: start() already cancels/reaps its own
run task when the caller's connect timeout cancels start() itself, so
_connect_server() must propagate cancellation without awaiting a
redundant shutdown() inside a cancelled context. Non-cancellation
failures on the unclaimed (standalone probe) path still reap the parked
task, now with the reap failure logged instead of raising over the real
error.
Also maps mrz@mrzlab630.pw for the attribution check.

_stop_mcp_loop() stopped and closed the background loop without reaping
the tasks still on it. A task left suspended is resumed later by the GC,
whose finalizer drives its cleanup against the now-closed loop:
Exception ignored in: <coroutine object MCPServerTask.run ...>
File "tools/mcp_tool.py", line 2947, in run
parked = await self._wait_for_reconnect_or_shutdown(
File "tools/mcp_tool.py", line 2161, in _wait_for_reconnect_or_shutdown
t.cancel()
RuntimeError: Event loop is closed
shutdown_mcp_servers() only reaps servers held in _servers, so a server
that parked after exhausting its initial-connect budget — never inserted
there, because start() raises _error before the caller registers it — has
no owner to signal it and stays suspended until the loop is gone.
Drain the loop the way asyncio.run() does: cancel the remaining tasks and
gather them while the loop is still open, so each runs its own finally.
Cancel alone is not enough — Task.cancel() only schedules the throw.
This resolves the reported traceback, but not the ownership bug that
strands the task in the first place; that needs a follow-up. Deliberately
not using "Fixes" so #60197 stays open for it.

The voice-interruption fix (5081551f0) covered the Python surfaces (CLI +
TUI gateway) but the desktop app has its own mic path in voice-barge-in.ts,
which still had both bugs on Windows:
- HALF-DUPLEX GAP: the barge monitor only opened when TTS playback started;
during LLM generation no mic was listening at all.
- PLAYBACK DEAFNESS: the monitor calibrated its noise floor while the
speakers were already playing TTS, baking bleed into the floor. On
Windows, Chromium echoCancellation does not reliably cancel same-app
output (measured live: quiet floor ~35-50 RMS vs playback bleed
600-1700 RMS), making the trigger unreachable.
Changes mirror tools/voice_mode.full_duplex_listen:
- voice-barge-in.ts: phase-aware full-duplex monitor — quiet-only
calibration (floor held through playback, never recalibrated against
bleed), playback min-trigger clamp + ceiling, 500ms grace on playback
onset only, windowed-majority detection.
- use-voice-conversation.ts: monitor arms at turn submit and spans
generation + playback (ensureBargeMonitor, idempotent). Mid-generation
speech fires the new onInterrupt callback; spoken stop-word during a
barge ends the conversation; submit waits for the interrupt to settle.
- use-composer-voice.ts + composer/index.tsx: plumb onInterrupt: haltRun
(same seam as the Stop button).
Tests: use-voice-conversation.test.tsx (6 tests) covering monitor lifecycle
across generation + playback, mid-generation interrupt, stop-word handling.
npm run typecheck + eslint clean; remaining desktop vitest failures
reproduce on a clean tree (pre-existing Windows env failures).
Salvaged from #31671 (@Shizoqua). The config-cache half of that PR was
superseded on main (9b8b054c2d gave _load_config_safe a readonly path),
but this cron-scanner half is still live: _strip_cron_safe_constructs
used re.search + a single str.replace, which only scrubbed occurrences
IDENTICAL to the first match. A cron job loading several GitHub skills
carries heterogeneous auth-header curl forms (-H vs --header, quoting,
token var names) — every non-identical block tripped the
exfil_curl_auth_header detector on every tick, blocking legitimate
GitHub cron jobs.
Now re.sub scrubs every occurrence; the trailing [^\n]* consumes the
URL path so no dangling fragment remains. Sabotage-verified: the old
implementation false-blocks the heterogeneous two-skill prompt the new
regression test pins; exfil to a non-GitHub host is still blocked.
79/79 cron tool tests green.
Follow-up to the #68246 salvage. The backend permission-mode resolution
only checked the DB session_id the tool path passes, but gateway /yolo
keys approval bypass off the gateway session_key (contextvar). Consult
both namespaces so /yolo works on messaging platforms, not just CLI/TUI.
Adds a regression test driving the real approval contextvar + yolo
toggle path E2E.
GatewayRunner carried ~19 separate Dict[str, ...] attributes keyed by
session_key, each with an ad-hoc lifecycle. They now live in one
`self._sessions: dict[str, SessionState]` (gateway/session_state.py) with
three lifecycle scopes and a `_session_state(key)` get-or-create accessor.
Mechanical refactor: same state, same semantics, new container.
Migration table (dict -> old decl line -> current clear path -> new home):
| legacy dict | decl | cleared by (before) | SessionState field |
|------------------------------------------|-------|--------------------------------------------------|----------------------------------------|
| _running_agents | 3505 | _release_running_agent_state; stop() .clear() | turn.agent |
| _running_agents_ts | 3506 | same | turn.started_ts |
| _active_session_leases | 3507 | same (+ lease.release()) | turn.lease |
| _busy_ack_ts | 3539 | same | turn.busy_ack_ts |
| _turn_lease_tokens ((key, gen)-keyed) | 3518 | _release_turn_lease (generation-guarded) | turn.lease_token + turn.lease_generation |
| _session_model_overrides | 3585 | _CONVERSATION_SCOPED_STATE funnel | conversation.model_override |
| _pending_one_turn_model_restores | 3586 | funnel; one-shot pop in turn finally | conversation.one_turn_restore |
| _session_reasoning_overrides | 3589 | funnel; lazy-init dict swap ~5692 (RACE) | conversation.reasoning_override |
| _session_service_tier_overrides | 3592 | funnel; lazy-init dict swap ~5738 (RACE) | conversation.service_tier_override |
| _last_resolved_model ("*" = process-wide)| 3527 | funnel | conversation.last_resolved_model |
| _queued_events | 3537 | funnel; lazy-init dict swap ~5204 (RACE) | conversation.queued_events |
| _pending_turn_sidecar_notes | 3597 | funnel; lazy-init dict swap ~19832 (RACE) | conversation.sidecar_notes |
| _session_ephemeral_pin | 3601 | agent-cache evict pop; lazy swap ~19885 (RACE) | conversation.ephemeral_pin |
| _session_vc_last | 3604 | agent-cache evict pop; lazy swap ~19864 (RACE) | conversation.vc_last |
| _pending_approvals | 3611 | boundary security funnel; stop() .clear() | persistent.approvals |
| _update_prompt_pending | 3623 | security funnel; update watcher pops | persistent.update_prompt_pending |
| _pending_native_image_paths_by_session | 3538 | one-shot consume; lazy swap ~12944 (RACE) | persistent.native_image_paths |
| _pending_messages (runner-level, str) | 3519 | _interrupt_and_clear_session pop; stop() flush | persistent.pending_command_text |
| _session_run_generation | 3540 | NEVER (monotonic, #28686) | persistent.run_generation (never reset)|
Races eliminated: every `self._X = {}` lazy-init/reset replaced the WHOLE
dict, so a writer on session A racing a lazy init triggered by session B
could lose its entry. All six such sites (_session_reasoning_overrides
~5692, _session_service_tier_overrides ~5738, _queued_events ~5204,
_pending_turn_sidecar_notes ~19832, _session_ephemeral_pin ~19885,
_session_vc_last ~19864, _pending_native_image_paths_by_session ~12944,
_turn_lease_tokens ~13644) are now per-session field writes on an existing
SessionState; a reset can no longer cross sessions structurally.
Registry successors:
- _release_running_agent_state -> state.turn.clear() (one structured reset
instead of the drifting pop-list; still pops the slot lease and calls
lease.release() first; still generation-guarded).
- _CONVERSATION_SCOPED_STATE funnel -> state.conversation.clear(); the
tuple is retained for legacy plain-dict stores not yet folded in
(_pending_model_notes) and for the public test contract.
- _turn_lease_tokens' (key, generation) tuple key -> lease_token +
lease_generation fields; release/rebind only match when the generation is
current, preserving the #28686/#64934 ownership check.
- _session_run_generation stays monotonic on persistent.run_generation and
is never cleared (conversation boundaries and turn releases don't touch it).
Compatibility adapters: tests (and a few mixin call sites) access the old
dict names directly (137 direct assignments to _running_agents alone), so
each legacy name is kept as a thin @property returning a live MutableMapping
view over the corresponding SessionState field (legacy_dict_property /
legacy_lease_token_property in session_state.py). Setter accepts a plain
dict (the `runner._X = {...}` test pattern); views support ==, in, len,
.get/.pop/.clear. The shutdown path in _stop_impl deliberately keeps
duck-typed legacy-attribute access because test fakes borrow it with plain
dicts.
Name collision noted (NOT touched, out of scope): gateway/platforms/base.py
has its own _pending_messages Dict[str, MessageEvent] (adapter-level slot);
the runner-level Dict[str, str] of the same name is what moved to
persistent.pending_command_text.
Entry leaks preserved (follow-up, no new eviction in this PR): SessionState
entries in self._sessions are never evicted, matching the old dicts — e.g.
_last_resolved_model, _session_run_generation, _session_vc_last entries for
dead sessions leaked before and their fields still occupy a SessionState now.
Verification: 123 tests/gateway files referencing the old names +
_release_running_agent_state + _CONVERSATION_SCOPED_STATE all pass (sole
failure test_feishu.py::test_websocket_sdk_accepts_channel_ua_tag is
pre-existing, stash-verified); 8 non-gateway test files touching the names
pass (266 tests); `import gateway.run` subprocess smoke OK; ruff clean;
post-migration grep shows zero non-comment `self._<oldname>` references in
run.py outside the property adapters and the duck-typed shutdown block.
The earlier scrub covered adapter.py; nine internal QA-campaign tracker IDs
remained in the two new test files, including a module docstring and an
assertion message. They mean nothing to a future reader — describe the
behavior instead. Comments only, no assertion changes.
Both relay Slack knobs read their value through bool(), while the native
adapter they mirror uses str(raw).strip().lower() in {"1","true","yes","on"}.
A YAML-quoted string diverges:
dm_top_level_threads_as_sessions: "false" → relay True, native False
Non-empty strings are truthy, so the escape hatch is silently ignored in
exactly the shape an operator writes to switch it OFF. reply_in_thread has the
same defect and gates reply placement, session keying and run.py's progress
resolver, so one quoted "false" misfires three ways.
Route both through a shared _coerce_flag mirroring native's predicate. Real
booleans pass through untouched; None falls back to the default. Contract §8
documents the accepted spellings.
Tests: both knobs parametrized over the true/false spellings native accepts,
plus the absent-key default.
The DM thread-anchor contract was resolved only in send(). _send_media() —
backing send_image, send_image_file, send_voice, send_video and send_document
— passed reply_to straight to the frame and never touched metadata, so
attachments egressing through the same connector-side Slack sender got both
failure shapes this branch set out to remove:
flat mode → reply_to survives, the image threads UNDER the user's DM
message (the original reported symptom)
thread mode → no metadata.thread_id, and threadTs() never reads reply_to,
so the image lands in the home channel instead of the
per-message thread
Both are reachable: gateway/run.py delivers agent artifacts through
send_voice/send_document.
Extract the three steps that must always happen together (mode gate, mirrored
reply_to_message_id strip, metadata promotion) into
_apply_slack_thread_anchor and route BOTH lanes through it, so text and media
cannot drift again. The media lane copies caller metadata rather than mutating
it — these helpers are called in loops with a shared mapping.
Also fold send_typing/stop_typing's duplicated status-anchor blocks into
_with_status_thread_anchor. They had already drifted (stop_typing omitted the
platform check) and the clear must target the thread the heartbeat set or the
status line sticks until Slack's own timeout.
Tests: media lane pinned in both modes plus the channel and
no-caller-mutation cases; verified as real by reverting the fix and watching
them fail.
Three provably-safe optimizations for O(n)-per-iteration history walks:
1. sanitize_tool_call_arguments: optional identity-keyed cursor (strong
refs to the exact validated message objects) skips re-json.loads-ing
already-validated history each loop iteration. Any list rewrite
(compression, repair, undo, steer) breaks the identity prefix match
and forces re-scan from the divergence point. Wired via a per-agent
cursor dict in conversation_loop.
2. estimate_messages_tokens_rough: per-message memo keyed on a deep
identity fingerprint (strings pinned by strong reference so id()
aliasing is impossible; scalars by value; dicts/lists structurally
with key order). Equal fingerprints imply identical str(shadow)
bytes, hence identical estimates. Unfingerprintable shapes fall
through to direct compute. Bounded FIFO cache (4096 entries).
3. _flush_messages_to_session_db_unlocked: bounded scan that skips the
identity-matched prefix of the previous successful flush's snapshot.
Snapshot only taken on full success; cleared on exception. Compression
rewrites use fresh copies, breaking identity and forcing full re-scan.
Parity proven in tests/agent/test_cursor_optimizations_parity.py:
500-message synthetic histories with tool calls, malformed args, unicode,
element-wise old==new across 3 iterations incl. simulated compression.
Measured (median of 5): sanitize 0.097ms->0.011ms, tokens 1.145ms->0.853ms,
persist-scan 179.5us->10.0us at 500 messages.
The test passed on dev boxes where a cua-driver binary is on PATH but
failed in hermetic CI: _call_tool_via_cli hit resolve_cua_driver_cmd()'s
install-hint early exit before reaching the spawn-env assertion. Pin the
resolver so the test exercises the code path it actually asserts.
Follow-up to the #62821 salvage: the _cua_driver_supports_no_overlay
--help probe is another Windows-reachable spawn; give it the same
windows_hide_flags() treatment. Also adjust the status test to stub
_resolve_driver_cmd (permissions.py resolves via that helper, not
shutil.which).
A Windows-installed cua-driver can return an absolute
``C:\Users\...\cua-driver.exe`` mcp_invocation.command to a Hermes
process running inside WSL. POSIX spawning can't use the raw Windows
string even though the binary is reachable through DrvFS. Translate
``<drive>:\...`` to ``/mnt/<drive>/...`` in _resolve_mcp_invocation
(before the path-separator check, since backslash is not a separator
on POSIX), only when actually running under WSL.

Same sibling-mock class as the relay-metrics runtime file — this test
stubs the telemetry gate's config read, which now goes through
read_raw_config_readonly(). Swept the whole test tree for remaining
read_raw_config stubs: all others target consumers that still use the
mutable reader (browser config, url_safety, inventory) and carry no
telemetry keys.
enabled() now reads via read_raw_config_readonly(); the 7 monkeypatch/
patch sites in test_relay_shared_metrics_runtime.py that stubbed
hermes_cli.config.read_raw_config no longer intercepted the read,
failing 18 tests on CI slice 7/8. Repro'd locally, retargeted the
mocks; 147 passed + 2 skipped across both relay metrics files.
Four hot-path consumers paid a full config deepcopy per read:
- telemetry gate relay_shared_metrics.enabled() — runs 2-3x per agent
turn (2x per API call from lifecycle hooks + 1x per tool call) and
called read_raw_config(), which deepcopies the whole raw config every
call. New read_raw_config_readonly() serves the cached dict directly:
248 us -> 4.6 us per call (54x) on Teknium's real 77-key config.
- interruptible_streaming_api_call local-endpoint stale-timeout branch
called load_config() once per API call for every local-model user.
- gateway get_inbound_media_max_bytes() + _get_ephemeral_system_ttl_default()
called load_config() on per-message paths. All three switched to
load_config_readonly() (345 us -> 12 us; PR #28866 lineage).
Together these account for ~90% of the ~1,900 deepcopy primitives per
turn measured in the 26-call stubbed-LLM profile.
read_raw_config_readonly() keeps the (mtime_ns, size) freshness key so
config edits are picked up next call, and preserves the identity
invariant (cache-miss returns the same object later hits serve) —
regression-tested with 'is', per the PR #28866 identity-bug lesson.
The mutable read_raw_config() is unchanged for save-path callers.
581 targeted tests green (config, relay metrics x2, ephemeral reply,
platform base, new readonly suite).
A live tool run renders its rows inside a ticker — a window exactly one
line tall that offsets to the newest row. Expanding a row inside it left
the row's output clipped to that line, and the next call ticked it away
entirely.
Opening a row is a request to read it, so the run gives up the window
until it settles: the ticker unmounts and the rows render at full
height, the same escape an approval already had.
_load_approval_mode now delegates to tools.approval._get_approval_mode,
which reads config via hermes_cli.config.load_config — that path resolves
HERMES_HOME from the environment, not the server module's _hermes_home
attribute. The four approval-mode tests only monkeypatched the module
attribute, so the resolver silently read the developer/CI real config
(default 'smart') instead of the temp fixture. Behavior assertions are
unchanged (invalid → manual fail-safe, YAML off-bool → 'off', three-way
persist + live emit); the fixtures now also set HERMES_HOME so the
canonical read path sees the same temp config.
