/review takes the last 10 chat messages plus optional instructions,
spawns a full-privilege background subagent (the async delegation
rail) that investigates the referenced work (PR, code, docs), and its
complete review re-enters the spawning session as a normal
async-delegation completion the primary agent can act on.
- agent/review_engine.py: shared engine (snapshot, briefing,
auxiliary.review credential resolution, dispatch, note formatting)
- tools/delegate_tool.py: internal credentials_cfg per-call override
(never model-facing) resolved through the same credential system as
delegation.provider pins
- auxiliary.review config block (provider/model/base_url/api_key/
api_mode); provider auto + empty model = inherit the main model
- Surfaces: CLI process_command, gateway run.py dispatch +
slash_commands handler (binds the approval session key so the
completion routes back), TUI/Desktop live dispatch in
tui_gateway/server.py, CommandDef registry (+Slack /hermes-only cap)
- Docs: delegation.md section + slash-commands.md (both tables)
- Tests: 15 engine tests (sabotage-verified: credentials_cfg and
dispatch tests fail without the fix), 4 gateway handler tests
through the real async rail
- Clear the accidental end stamp on resurrection (at the lineage tip):
a surviving ws_orphan_reap/agent_close reason made a LATER deliberate
archive auto-resurrect on the next lookup — the user could never retire
the canonical chat. Test pins the resurrect -> deliberate-archive ->
stays-archived cycle.
- Judge recoverability at the compression TIP: the registry row of a
compressed lineage carries end_reason='compression', so tip-stamped
accidents were unrecoverable through the registry row. Lineage test.
- Heal the third lookup: the api_server exact-title listing (hermes peer
dm resolution) filtered archived rows out via list_sessions_rich and
still failed for reap-archived canonical chats.
- Single source of truth for the recoverable set: tuple moved to
hermes_state_common (mirroring _RESET_END_REASONS_SQL) and interpolated
into all three recovery SQL sites — literals cannot drift.
- methods_session gate uses BOT_CHAT_TITLE (not a literal) and re-fetches
by id after resurrection (title has no DB-level UNIQUE).
- Idempotence pinned: two consecutive profiles.list calls both resolve.
A /p/<profile>/ URL prefix on a gateway with multiplex_profiles off was
silently ignored: the request was handled as the gateway-owning profile,
so /p/lokaj/v1/toolsets reported the OWNER's platform_toolsets (and every
other profile-owned config read — skills, capabilities, model options,
agent-run toolset resolution — resolved from the owner too). That is the
exact repro in #91583 defect 2: enabling computer_use with
'hermes -p lokaj tools enable computer_use --platform api_server' showed
enabled in lokaj's config while /p/lokaj/v1/toolsets stayed false, and
enabling it on the owner profile flipped it true.
Per-profile capability isolation is the intended design (ruling on
a different profile's config. Multiplexed gateways were already correct —
the profile-prefix middleware enters _profile_runtime_scope and every
canonical config loader honors the HERMES_HOME override contextvar
(verified empirically for load_config, get_config_path and
_load_gateway_config) — the leak was only the non-multiplex fallthrough.
Fix at the one seam both adapters share: _resolve_request_profile now
rejects (404) a prefix naming any profile other than the one the gateway
actually serves. A self-referential prefix (/p/default/ on the default
gateway, /p/lokaj/ on a gateway launched for lokaj) still falls through
so existing well-formed clients keep working. Same change in the webhook
adapter, which had the identical fallthrough. New shared helper
hermes_cli.profiles.profile_matches_home does the home comparison,
fail-closed.
Tests: tests/gateway/test_multiplex_toolsets_profile_isolation.py —
E2E-style with two real profile homes + config.yamls under a temp
HERMES_HOME, real aiohttp routing through the profile-prefix middleware:
per-profile /p/<x>/v1/toolsets isolation for both owner and secondary
(the #91583 repro asserts computer_use true under /p/lokaj only),
cross-profile key rejection, and the fail-closed non-multiplex prefix
for both adapters. Sabotage-verified: reverting the adapter change fails
the 3 fail-closed tests.
Fixes#91583 (defect 2). Repro and live validation by @kubaboski.
The prefix is an address: the caller is naming WHICH agent the request is
for. With gateway.multiplex_profiles off, _resolve_request_profile ignored
the prefix entirely — "don't 404 a would-be valid route" — so a request
explicitly addressed to one agent was silently answered by a different one.
Observed live (Aug 2026): `hermes peer dm mini/researcher` was answered by
the mini's DEFAULT agent with no error on either side, because that host
runs one LaunchDaemon per profile and only the default daemon hosted an
api_server. A wrong-agent answer is strictly worse than an error: the
sender believes the addressee got the message.
With multiplexing off the process serves exactly one profile, so the prefix
is honored when it names that profile (peers address single-profile daemons
this way without knowing the host's topology — get_active_profile_name() is
the same identity the file already uses for model resolution) and rejected
otherwise through the existing _PROFILE_REJECTED path (404). A process that
cannot resolve its own identity rejects too: if it cannot prove who it is,
it must not answer as anyone.
Unprefixed requests are untouched, and multiplexed hosts are untouched —
the change is confined to the prefix-present, multiplexing-off branch that
previously discarded the caller's addressing.
Widen the DM tempfile-leak fix (#91902/#92407) to the sibling sites
PR #92784 introduced:
- tools/bot_relay.py: expose the 6h stale sweep as
cleanup_bot_relay_artifacts() (cleanup_*_cache contract) and wire it
into gateway housekeeping — previously it ran only when the Desktop
drained the outbox, so plaintext envelopes/replies queued while the
Desktop was away could sit on disk forever.
- tui_gateway/methods_bot_relay.py: move the payload write inside the
try/finally so a failed write no longer leaks hermes-relay-dm-*.txt.
- tools/bot_mode_dm.py: _spawn_delivery takes dm_file=None for relay
waiter deliveries, which have no plaintext DM tempfile to reclaim.
The in-band sweep in _write_dm_file only runs when another DM is
written — a gateway that never sends one keeps orphans forever. Expose
the sweep as cleanup_bot_dm_cache() with the same contract as the other
cleanup_*_cache helpers (returns files removed) and wire it into the
gateway housekeeping loop on the hourly media-cache cadence. Also sweeps
legacy hermes-dm-*.txt and hermes-relay-dm-*.txt orphans in the OS temp
root.
Folded in from #92407 (mehmetkr-31), adapted to the runner-owned
cleanup design salvaged from #91902.
Bot Mode always hides canonical 'Bot Chat' sessions, but _find_bot_chat's
GET /api/sessions listing used the default include_hidden=False path, so
the existing hidden row was invisible, _ensure_bot_chat tried to create a
duplicate, and the peer DB's UNIQUE(title) guard rejected it — DM failed.
- api_server: GET /api/sessions now accepts an exact-title lookup
(?title=...) and honors include_hidden=1 ONLY alongside a title filter,
so canonical hidden rows resolve without exposing a blanket hidden
listing on the client surface. The title needle is pushed into SQL
(search_query) so old hidden rows outside the recency window are found.
- peer dm client: _find_bot_chat sends title + include_hidden=1; older
peers ignore the unknown params and degrade to today's behavior.
- Clear diagnosable error on the older-peer duplicate-create rejection,
naming the hidden canonical chat and the PATCH hidden:false workaround.
- Unit tests (hidden resolution, no duplicate create, older-peer error,
older-peer visible fallback) + real-gateway E2E over a real state.db.
Root-cause analysis and regression recipe by @kubaboski in #91583.
Fixes#91583
- bind under umask 0o177 so the socket is never world-connectable, even
pre-chmod (review pt 3)
- verb handlers run in an executor: state-file reads stay off the
adapter event loop (pt 2)
- inventory dedupes one multiplex gateway answering identify for several
homes — one runtime record per pid, with regression test (pt 1)
- v1 wire contract (one request per connection) documented in the module
docstring (pt 5); /tmp-unwritable skip in the short-home test
Live-verified: perms 600 at bind, identify 4.3ms via executor path, 20
rapid queries healthy.
CI runners put pytest tmp roots past sun_path, which routed every test
home through the fallback: two tests assumed in-home binding. Tests now
assert against the resolved bind location, and the fallback itself
prefers /tmp when tempfile.gettempdir() is too deep to fit sun_path.
The gateway now creates a local control socket at startup (Unix domain
socket at $HERMES_HOME/gateway.sock with a pointer-file fallback for
long paths; named pipe on Windows) and answers versioned JSON verbs:
- identify: pid, profile, hermes_home, code_sha/code_version (#91283
stamps, now queryable live), self-declared supervisor kind, start_time
- status: the live runtime-status payload, answered by the process itself
Bound immediately after the PID-file O_EXCL claim (the moment the
process becomes the authoritative gateway for its HERMES_HOME), removed
on clean shutdown; a successor clears any stale socket on bind. Strictly
non-fatal: bind failure only means consumers use the old path.
Consumers migrated (observability only, scan layer demoted to fallback,
never deleted):
- collect_fleet_versions() (post-update fleet matrix): prefers a live
identify answer over gateway_state.json; entries carry source=socket
- collect_runtime_inventory() (hermes update --plan): prefers the
socket, and takes the gateway's own supervisor declaration instead of
inferring it from PID scans
Old gateways mid-upgrade, crashed processes, and bind failures behave
exactly as before. Never a TCP port; filesystem/pipe ACLs are the auth
boundary (0600 socket).
Part of #91277 (fleet-update reliability). Design: #92091.
Addresses both review findings from @egilewski on #89134:
- Non-finite values: _coerce_int now degrades int(inf) (OverflowError
previously ABORTED gateway config loading); the clamp requires
math.isfinite plus sane upper bounds (interval <=3600s, timeout
<=600s, strikes <=1000), falling back to the shutdown_watchdog
constants.
- Loader wiring: load_gateway_config builds gw_data FLAT and never
forwarded the yaml gateway: section, so loop_watchdog* keys —
including the PRE-EXISTING loop_watchdog bool documented in
config_defaults — were silently ignored on the real startup path.
Bridged with the established top-level-wins/nested-fallback pattern.
E2E: config.yaml with loop_watchdog:false + strikes:12 + interval:.inf
now yields False/12/30.0 through the real loader.
Downscope of the salvaged #89134 per review: the 3->8 default raise was
symptom tolerance for the false-positive class the off-loop heartbeat +
two-witness probe fixes at the root — fleet-wide it would only delay
genuine-wedge recovery ~2.7x. The three tuning knobs keep independent
operator value and stay:
- default max_strikes back to 3 everywhere (constant, dataclass,
from_dict fallback, floor clamp, tests)
- gateway/config.py + gateway/run.py now reference the
shutdown_watchdog DEFAULT_* constants instead of duplicating literals
in three places (drift hazard)
- knobs registered in hermes_cli/config_defaults.py alongside the
sibling gateway.loop_watchdog bool
The event-loop liveness watchdog (gateway.shutdown_watchdog) hard-exited with
code 75 after 3 consecutive missed probes (probe_interval=30s, timeout=10s,
max_strikes=3), i.e. ~90-120s of loop block. Telegram/Discord reconnect during
a network blip does synchronous socket I/O on the loop and can block it for
60-90s; these stalls self-recover (recurring fleet incidents on 2026-08-17
stalled cron dispatch ~21h via restart churn, kanban t_0f76430f).
Raise the default max_strikes 3->8 so a transient reconnect stall is tolerated
while a genuine multi-minute wedge still escalates, and expose the three
tolerance knobs via config.yaml (gateway.loop_watchdog_probe_interval_s /
_probe_timeout_s / _max_strikes) so operators can tune per deployment.

hermes_cli/gateway.py's restart-wait sizing (from #92175) was the only
cross-module import of an underscore-private shutdown_forensics helper.
Promote it (private alias retained for existing patchers).
The notifier watcher offloads the same class of guarded Kanban writers
(_kanban_advance/_kanban_rewind/_kanban_unsub) as the dispatcher ticks
that #92172 wrapped. Apply the same offload-boundary scrub to all 10
writer sites for uniform defense-in-depth (read-only _collect stays on
bare to_thread), and reword the helper docstrings to state the
defense-in-depth relationship to spawn isolation accurately.
Post-merge follow-up to #92173. The claim + resume-clear lived inside
the boot-send task AFTER the restart notification — itself a
flood-controllable send. If that notification outlived the restore-gate
timeout, the gate opened with zero rows claimed and the resume
scheduler replayed turns whose answers were already in the ledger,
while the background task later redelivered them too (duplicate
delivery + re-paid turn).
Split _redeliver_pending_obligations into _claim_pending_obligations
(pure DB: sweep + resume clear, awaited inline before the send task
exists) and _redeliver_claimed_obligations (network half, stays inside
the bounded task). The original name remains as a composition wrapper.
Mutation-checked: both updated gate tests fail on pre-split run.py.
Spawn-time Context isolation cannot rewrite an already-running watcher task. Run dispatcher SQLite offloads in an empty Context so write_txn no longer false-trips after delegate_task, while real child callers still hit the mutation guard.
Review of #90448 by @andrexibiza: adding _ensure_reconnect_watcher_running()
to the already-queued branch of a fatal callback is still an event-coupled
check. It needs a later fatal error from some other platform to arrive, and
#81036 makes that less likely rather than more -- it publishes the queue
before disconnect and drops the failed adapter from the live map, so after
the watcher's supervised restart budget is spent there may be no adapter
left to emit the event recovery is waiting on.
That is the state #72366 (salvage of #71867 by @ygd58) restored supervision
to close: queued work exists, the watcher is dead, and nobody owns the
invariant. Supervision being finite is correct; having no owner past the
budget is not.
_spawn_supervised now takes on_give_up, invoked when it abandons a task --
the supervisor is the only thing that knows it has. The reconnect watcher
uses it to hold:
while _running and _failed_platforms is non-empty, either a reconnect
watcher is live or a bounded respawn is scheduled.
Empty queue: leave it down and log; the enqueue path spawns a fresh watcher
the moment something depends on one. Non-empty: a bounded slow tier at
_RECONNECT_WATCHER_SLOW_RETRY_SECS (300s) for _MAX_SLOW_WATCHER_RESPAWNS (6)
attempts, standing down early if the queue drains or a watcher returns on
its own. Exhausted: one loud error naming the platforms left unattended.
The ceiling is (1 + _MAX_SUPERVISED_RESTARTS) x (1 + _MAX_SLOW_WATCHER_RESPAWNS)
spawns -- 42 across at least half an hour -- because each slow attempt hands
the watcher a fresh supervised budget. A test asserts that ceiling so it
cannot quietly become a restart loop.
Deliberately NOT included: requesting a process restart when the slow tier
is also exhausted. Taking down every healthy platform to heal a sick one is
a blast-radius policy decision for a maintainer.
Two things this turned up:
- _spawn_supervised did not thread on_give_up through its own backoff
respawn, so the callback was lost after the first restart and the give-up
branch had no owner at exactly the moment it needed one -- the same defect
the on_spawn docstring warns about, one parameter over.
- Three call sites repeated the (factory, name, on_spawn) triple, whose
on_spawn half is load-bearing. They now go through
_spawn_reconnect_watcher().
_supervised_backoff() names the previously-inline exponential schedule so
the exhaustion tests can collapse it; production behaviour is unchanged.
Refs #90386
_ensure_reconnect_watcher_running() exists for one situation: the reconnect
watcher has exhausted _MAX_SUPERVISED_RESTARTS, so _spawn_supervised has logged
"giving up restarts" and will never bring it back on its own (#70344, and the
supervised-restart half of #71758). It had exactly one call site, inside the
newly-queued branch of _queue_retryable_fatal_platform.
That branch is unreachable for a platform already in _failed_platforms, which
is the only kind of platform the watcher can have been retrying long enough to
burn five rapid restarts on. So the backstop could not fire in the one state it
was written for.
The failure is silent by construction. The early return logs nothing, so there
is no "queued for background reconnection" line. The stranded check in
_handle_adapter_fatal_error_detached deliberately treats a queued platform as
safe, so the gateway does not exit for the service manager either. With another
platform still connected, self.adapters is non-empty and the "gateway staying
alive, watcher will retry in background" branch is skipped too. A retryable
fatal error can therefore produce a single ERROR line and then nothing: the
platform sits in the queue that nobody is draining until someone restarts the
process by hand (#90386 reports 4h17m of that, with cron unaffected throughout).
Call the ensure on the already-queued path as well. It is already idempotent
and already cheap: it returns immediately unless the tracked task is done, and
it routes through the same on_spawn handle tracking, so a live watcher is never
duplicated.
The queue entry itself is deliberately left untouched. Re-enqueueing would
reset attempts and next_retry, restarting the backoff ladder on every fatal
error and hammering a provider that is already refusing the connection.
Follow-up to the salvaged #91986: the per-row clear still left rows the
loop had not reached exposed — a slow send ahead of them could hold the
loop past the inbound-gate timeout and let
_schedule_resume_pending_sessions replay those turns. Clearing every
claimed row up front closes the duplicate window; claiming already
spent the redelivery attempt, so the ledger retry path is unchanged.
Restart notification and obligation redelivery ran before the
startup-restore gate opened, so one hung Telegram send queued inbound
on every platform. Bound those sends with the same timeout the resume
gate already uses, and clear resume_pending before send so a timed-out
redelivery cannot also replay the turn.
Add the foreign-holder guard to gateway/session.py::_rebuild_fts_once(),
the third FTS rebuild path that was not covered by the original fix.
Also add a comment explaining why _fts_runtime_rebuild_attempted is set
before the foreign-holder check: the fail-open path that follows
persists FTS_STALE_KEY so the next startup retries via _recover_stale_fts.
_turn_transcript_messages pre-classified every message with
_is_compressed_summary_message (full content flatten + prefix scan), then
_message_response re-ran the same classifier inside its projection --
2x per non-summary row, 3x per summary row on every run.completed emit.
The outer guard was redundant: _message_response already yields
display_kind hidden for pure handoffs. One projection call per row now.
Surfaced by the post-merge simplify re-review of #91517/#91535.
Artifact receipts live only in memory, so files left behind by a dead
process were unreachable but persisted forever despite the advertised
300s TTL — a retention failure on the surface meant to be ephemeral
(blocker 4 of andrexibiza's #91535 review). A fresh ArtifactStore now
removes every artifact-id-shaped file and stale *.tmp with no index entry
(at construction the index is empty, so all such files are orphans).
Non-artifact-shaped names are untouched. Regression: store -> recreate
store over same root -> orphan+tmp gone, unrelated file kept.
The global broker snapshotted browser.extension_control.developer_mode once
at construction, so flipping it OFF in config did not revoke raw CDP/eval
from already-attached controllers until process restart — a revocation
failure at the highest-privilege browser surface (blocker 3 of
andrexibiza's #91535 review). select() now consults the live config on
every privileged selection (explicit bool still pins for tests); off->on
also unlocks without restart. Regression test drives both directions
against an attached controller. Also drops the dead back-compat
_artifact_store property (zero readers).
The frame handler returns reply dicts (heartbeat/detach acks) that the WS
reader loop sends back; the -> None annotation was the only new ty
diagnostic vs origin/main.
Addresses both merge blockers from @andrexibiza's review of #85351:
1. HTTP-uploaded artifacts could never be consumed by broker dispatch:
artifact_scope_key hashed (principal, session, family), the HTTP routes
store with an EMPTY session (API-key auth has no server session) while
broker validation carries a session-bearing ControllerScope — every
real upload->dispatch journey died with ArtifactScopeMismatch
(reproduced before fixing). Canonical ownership is now
principal/transport-family (documented in the scope-key docstring);
ids stay unguessable server-minted 32-hex and downloads one-shot.
New composition regression: HTTP-shape upload -> registered controller
scope -> broker artifact dispatch, mutation-checked (re-adding session
to the key makes it fail).
2. The 'profile-scoped' artifact store was first-profile-wins process
state: one adapter-level singleton pinned profile B to profile A's
physical root on multiplex listeners (same frozen-handle class as
#88734). Stores are now cached by resolved profile, and the broker
selects the store from the controller scope's profile_id (default-slot
fallback preserves single-profile/test behaviour). New A/B multiplex
regression proves distinct physical roots regardless of touch order.
Also documents the advertised ticket_expires_at as best-effort wall clock
(broker enforces expiry monotonically) per review feedback.
browser_control_enabled()/browser_control_developer_mode() run on every
browser tool call and inside every check_fn evaluation (uncached for bound
sessions). Both are pure reads of nested dicts; load_config()'s defensive
deepcopy (~135us/call) is wasted there. Same pattern as the other read-only
config probes.

- Rename the broker's TicketInvalid to ControllerTicketInvalid: the same
exception name already exists in hermes_cli/dashboard_auth/ws_tickets.py
and BOTH are caught in the same WS auth flow this feature touches — two
unrelated same-named exception types in one blast radius invited a wrong
except clause.
- Import the 'server-internal' sentinel identity from its canonical
definition (ws_tickets.INTERNAL_USER_ID/INTERNAL_PROVIDER) instead of
re-declaring the strings; drift would have silently broken the
internal-peer exclusion in _is_authenticated_identity.

attach/disconnect/detach acquire a per-controller threading.Lock that a
worker-thread dispatch can hold for up to 10s while blocking on the event
loop to transmit its command frame (run_coroutine_threadsafe +
result(timeout=10)). Acquiring that lock synchronously from loop context
(controller WS finally, frame handler, gateway WS teardown) could park the
ENTIRE gateway event loop behind the send bridge — a deterministic
multi-second global stall whenever controller teardown raced an in-flight
command. All loop-context broker calls now go through asyncio.to_thread,
matching the existing offload pattern for _close_sessions_for_transport.

The router treated any server-stamped principal as a bound lane, so with the
flag ON every authenticated dashboard/API session lost the legacy browser
backend even when no extension controller ever registered (scope_for_session
returns None -> ControllerUnavailable, no fallback) — while check_fns still
advertised the tools via the legacy OR-gate.
New broker.lane_registered() distinguishes the two cases:
- lane never registered -> generic callers keep the legacy backend
- lane registered (controller offline/ambiguous) -> fail closed, unchanged —
a control-this-tab session never silently jumps to another browser
Also makes the four non-allowlisted wrapped tools (cdp/console/vision/
get_images) behave correctly for never-registered lanes (legacy backend)
while staying fail-closed for registered lanes.

Treat unexpected controller transport loss as recoverable until each command's original deadline. Same-identity reconnects refresh transport and capability state, flush deferred cancels before new dispatch, and can complete already-started work.
Keep explicit detach and different controller/browser identity replacement terminal, owner-gate every inbound lifecycle frame, distinguish slow in-flight WebSocket writes from real send failures, and exclude browser-control session identity from shared shell snapshots.
Keep extension control opt-in and preserve existing browser backends unless an exact server-bound controller is available. Centralize protocol and capability admission across API and dashboard transports, make selected-controller results authoritative, bypass stale availability caches only inside bound requests, and serialize structured results for the existing tool contract.
Add a real browser_snapshot route-table/WebSocket E2E, strict admission and ownership regressions, public configuration and protocol documentation, and tests proving feature-off/no-controller compatibility.
