Unpinned cron jobs snapshot the global provider/model at creation and fail
closed when the global default drifts (#44585). Pinning was the only way
forward, but it makes a job stop tracking the global default forever.
Add resnap: refresh an unpinned job's provider/model snapshot to the CURRENT
global resolution without pinning it, so it adopts the user's deliberately
changed default while keeping tracking future changes. Single job via
cronjob(action='resnap', job_id=...) or hermes cron resnap <id>; bulk via
cronjob(action='resnap', all=true) or hermes cron resnap --all. Refuses to
guess scope when neither is given. The drift-guard alert now points at both
options (pin vs resnap). No inference call is made — it recomputes the
snapshot string from config.
Under gateway.multiplex_profiles the default gateway serves every profile, yet
four startup/status paths still reasoned from the wrong source:
* A secondary profile's API_SERVER_KEY (which the docs REQUIRE for /p/<profile>/
auth) auto-enabled api_server in that profile's config, so
_load_secondary_profile_config raised SecondaryPortBindingConfigError and the
whole profile was skipped. gateway/config_env.py::_enable_from_env now leaves
`enabled` alone for port-binding platforms while a multiplexer loads a
NON-default profile (home override + multiplex flag, the same signal
gateway.config uses for scoped reads); the credential still lands in extra so
the shared listener can authenticate the prefix. Default profile unchanged.
* "Is this profile served?" was re-derived from the default config.yaml plus
GATEWAY_MULTIPLEX_PROFILES as seen by the CLI process. `hermes -p coder ...`
loads coder's .env, so an env-only opt-in on the default profile was invisible
(guard never fired, status said stopped) and an allowlist edit flipped the
answer before the restart. named_profile_served_by_running_multiplexer now
reads the pid-verified default gateway_state.json served_profiles (written by
_record_served_profiles) first and falls back to config derivation only when
the key is absent. The record helpers live in hermes_cli/gateway_multiplex_served.py.
* The served-profile guard ran only inside `gateway run`. `hermes -p X gateway
start|install|restart` reached the service manager, whose unit then exited 78
forever (systemd parks it while the CLI prints "started"; launchd KeepAlive
respawns every 30 s). The service verbs now run the same guard up front
(exit 78, same message) and accept --force; the Desktop /api/gateway/start
route returns 409 for a served profile instead of spawning a doomed child.
* Status surfaces disagreed: `hermes -p coder status` said stopped, `hermes -p
coder cron status` said "cron jobs will NOT fire" while `cron list` said fine,
and the default `hermes status` never listed served profiles. Both now route
through the probe / the recorded served set. The -p/--profile matcher in
_scan_gateway_pids and gateway.status._command_line_belongs_to_profile compares
the flag token for equality (`-p ops` no longer claims -- or lets `gateway
stop` SIGTERM -- an `-p ops-2` gateway).
Docs: multi-profile-gateways.md now describes the start/install refusal, the
--force flags, the API_SERVER_KEY behaviour and the single default-home
gateway_state.json (the per-profile runtime_status.json claim was wrong).
Fixes#100397
Addresses #89726#97360#71344
(cherry picked from commit d002c1864a7b6a22c53758b16b7b0cc79aea2edf)
Route local producers to durable owner ingress before attempting the unowned
CLI lane. Preserve per-run/per-message IDs and receipt-first retry handling;
never fall back after ambiguous admission. Report cron admission as queued,
not completed or failed, in job status, the execution ledger and CLI/tool UX.
Native isolated Electron validation reproduces SESSION_NOT_OWNED on main for
both idle and busy owners. Fixed owner consumes idle cron, busy cron, local
DM and mounted-chat cron exactly once, keeps its lease, yields to queued
human input, and preserves the prior model-request prefix and tool schema.
Inference alone used a deterministic loopback wire stub; no paid model call.
Persist paused state, timestamp, reason and no first trigger in the original
locked creation write. Forward the same boolean contract across CLI, tool,
gateway API and dashboard API, validating at the store boundary. Preserve
explicit operator force-run behavior and normal enabled creation.
The live CLI probe also caught the command shim dropping failure return codes;
forward them so invalid creation reports exit 1 rather than success.
Credit earlier atomic-creation work in #78935 and #94952 and the focused
implementation in #104578. The broader manifest staging layer is not imported.

For each issue anchor present in BASE 63279301bc non-test .py and absent on HEAD, the BASE comment/docstring block was re-attached at the HEAD location of the code it explained (matched by the distinctive code line / enclosing def). Sentences already covered by an existing HEAD comment were deduped; the issue number always survives. Insert-only: no code lines changed.
Coatue FR (Frank Long): jobs delivering into shared channels publish
engine failure notices ('⚠️ Cron X failed…') to those channels with no
opt-out. Adds an optional per-job failure_deliver field sharing
deliver's grammar: on failure, targets resolve from failure_deliver
when set (local = structural silence; state still recorded in
last_status/last_error/run history). Success delivery is unchanged;
absent field = today's behavior byte-for-byte.
Honored by every failure-category engine notice: the run_job failure
summary (+streak nudge), the escaped-failure retry path, drift-skip and
blocked-config alerts (composed into the same delivery), and the
gateway-shutdown interrupted-run notice (_notify_interrupted_cron_jobs).
Surfaces: cronjob tool create/update (same bot-chat validation as
deliver; '' clears on update), hermes cron create/edit
--failure-deliver, docs tip in automate-with-cron.
Existing fake_deliver test doubles gained **kwargs for the new
for_failure keyword — signature-compat only, no behavior change.
De-risking for the notify=True UX change: the marker is now driven by
cron.delivery.notify (config.yaml, default true = current behaviour), read
once per delivery and applied to both the text and media routes; a missing or
malformed section keeps the default.
An evidence-free live-adapter ack (bare SendResult(success=True) from
Slack/Matrix/Mattermost) is still accepted, but the target is recorded on the
job as last_delivery_unverified (cleared by the next evidenced delivery) so
the state shows up in 'hermes cron list' (⚠ Delivery UNVERIFIED), 'hermes cron
doctor', and the cronjob tool listing — not only in a WARNING log line.
Live repro (real _deliver_result + real 'hermes cron list' against a temp
HERMES_HOME, Slack target, SendResult(success=True)): before — list showed
nothing beyond the Deliver line and route metadata always carried
notify=true; after — list prints the UNVERIFIED line, and
cron.delivery.notify: false yields notify=false in the route metadata.
A successful agent run whose delivery failed used to persist
last_status=ok and bury the failure in last_delivery_error. CLI list
painted that as green and the run looked identical to a quiet success.
Record last_status=delivery_failed instead, keep last_delivery_error,
do not increment failure_streak, and teach cron list/doctor not to
treat it as ok.
Fixes#83993
The catch-up machinery already re-ran jobs missed during gateway downtime,
but the late execution rendered as an ordinary on-time success — no
scheduled-vs-actual time, no lateness, no disposition (issue #99879, the
visibility half).
- Due-scan now persists a `last_dispatch` stamp on every recurring dispatch:
scheduled_at, dispatched_at, lateness_seconds, and kind
(on_time / late / catch_up, classified against the ticker tolerance and
the schedule's catch-up grace window). Manual triggers and one-shots are
not stamped (no scheduled instant to be late against / retired beyond
grace).
- `hermes cron list` renders a per-job Dispatch line; late/catch-up runs
show "⚠ catch-up after missed fire: scheduled ..., ran ... (31m late)".
- `hermes cron status` calls out jobs whose last dispatch was late or a
catch-up, in both the built-in ticker and external provider paths.
CLI surface only — no new tools, no policy engine.
Addresses the visibility half of #99879.
Widens the salvaged cron doctor with the highest-value fleet check:
an active job whose next_run_at is parked >15min in the past is not
firing (dead ticker, downed gateway, wedged fire-claim). Also registers
doctor in the docs (cron guide + CLI reference) and resolves the salvage
onto current main alongside runs/incidents/notepad.
A long-lived process whose checkout was updated underneath it (hot git
pull, interrupted hermes update) serves mixed sys.modules. When such a
stale process races a fresh gateway for the cron tick lock and wins the
minute, every agent job it dispatches can die on ImportErrors whose real
cause is staleness — and the fresh gateway's ticker skips the same minute
as lock-loser, so the user's scheduled job fires broken or not at all.
tick() now checks, BEFORE acquiring the tick lock:
skew detected (boot fingerprint != disk revision)
AND this process does not own the gateway runtime lock
AND that lock is held (a fresh gateway is alive)
-> raise CronTickYielded, skipping the tick entirely
Each arm alone keeps the old behavior:
- skew + self-owned lock -> proceed (delivery-path stale-code hint stays
the surface for gateway-owned dispatches)
- skew + no lock holder -> proceed (desktop-standalone users must not
lose their only ticker to a silent yield)
- skew None (non-git install, no boot fingerprint, probe failure) ->
proceed; yielding is a certainty claim, never a guess
The yield RAISES instead of returning 0 so the provider loops record it
via record_ticker_error and mark the heartbeat success=False — a yielded
tick must not look like a healthy one (hermes cron status shows why),
mirroring the EMFILE propagation contract (#87644). Yield logging is
throttled to once per skew episode. Self-healing: when the fresh gateway
dies, its lock releases and the stale ticker's next tick proceeds.
Multiplex loop: a yield for one profile no longer cancels sibling
profiles' ticks in the same cycle; only the yielding profile records an
unsuccessful beat.
gateway/status.py gains owns_gateway_runtime_lock() —
is_gateway_runtime_lock_active() is True for the lock's own owner too, so
a caller deciding whether to yield to a FRESH gateway needs the
in-process handle as the discriminator.
A named profile has no local gateway.pid, so cron warned that jobs
would not fire and recommended hermes gateway install — which the
start guard then refuses with exit 78. Share the multiplexer-serving
probe with the start guard and count it as liveness.
Repairs #98790 where
✓ Gateway is running — cron jobs will fire automatically
PID: 4165
Ticker heartbeat: 39s ago
4 active job(s)
Next run: 2026-08-30T22:50:18.762041+03:00 in profile B incorrectly reports
that jobs will fire based on profile A's gateway process.
Root causes:
1. executed ,
which enumerated the entire systemd fleet regardless of ,
violating the docstring "only PIDs belonging to the current profile".
2. checked when
(no heartbeat file) should trigger a warning — instead, it fell through
to the "✓ Gateway is running" green branch.
Changes:
- hermes_cli/gateway.py::_get_service_pids: pattern = get_service_name()
when all_profiles=False, filtering to the current profile's systemd unit.
- hermes_cli/cron.py::cron_status: guard hb_age is None first with an
explicit yellow warning: "ticker has not reported a heartbeat".
Regression test suite guards both systemd scoping (default + all_profiles)
and heartbeat branching (None vs fresh vs stale).
Sibling site of the salvaged #95947 fix (same file): cron_status
declared 'Gateway is not running — cron jobs will NOT fire' from a bare
find_gateway_pids() miss even while the runtime lock proved the gateway
alive. Now the not-running verdict requires both the scan AND the lock
to read dead; when only the lock answers, the pid line falls back to
the recorded gateway pid (or is omitted).
Two regression tests pin the false-alarm suppression and the genuine
not-running warning.
Follow-ups to the salvaged #95947 cron commit:
- Wrap the lock probe in its own try/except: a crashing probe is
'unknown', not 'dead' — the pid scan still decides instead of the
whole tri-state collapsing to None.
- Regression tests (shape adapted from #94155 by @liuhao1024): lock
held + empty pid scan -> alive (the reported false alarm); lock
inactive -> pid-scan fallback both ways; crashing lock probe still
falls back.
- patch_liveness now pins the lock probe inactive by default so the
pre-existing pid-scan tests stay deterministic on machines where a
real gateway holds the real lock.

_builtin_gateway_liveness() decides whether the builtin cron ticker can fire by
PID-scanning via find_gateway_pids(). That scan can transiently return empty even
while the gateway is up (e.g. just after a restart), so the in-gateway cronjob tool
emits a false 'Gateway is not running — jobs won't fire' while jobs are firing on time.
Prefer the gateway runtime lock: it is held for exactly the gateway's lifetime (a
reliable liveness signal), and inside the gateway process it short-circuits to True,
so the in-gateway check can never false-alarm. Fall back to the PID scan only when the
lock reads inactive (the external-CLI path).
* feat(cron): durable failure incidents with signature dedup and ack
Introduce a durable cron incident store (cron_incidents in the shared
cron/executions.db) that groups "same job + same error signature" across
runs, so a known recurring failure stops re-pinging the operator every run
once it has been acknowledged.
- cron/incidents.py: lazily-created incident table (detected -> alerted ->
reviewed -> closed lifecycle; closed is per-signature terminal), sha256
signature dedup over job_id + normalized error, redacted/truncated error
storage, failure-type classification, and ack/list/get/count helpers.
- cron/scheduler.py: record an incident on the failure delivery path and
suppress the per-run failure ping when the exact signature is acked (both
the normal failure path and the processing-raised retry path). Best-effort:
an incident-store error never breaks the cron run or delivery. Streak nudge,
alert-once markers, and delivery-error behavior are untouched.
- hermes_cli: add `hermes cron incidents [--state ...]` and
`hermes cron incidents ack <id>`.
- tests/cron/test_cron_incidents.py: dedup, lifecycle, redaction,
classification, lazy-schema, scheduler gating, and CLI coverage.
Non-goals deferred to later slices: Discord buttons/review view, HMAC action
tokens, owner-agent review launch, approval-gated fixes, incident playbooks.
* refactor(cron): tighten incident lifecycle, wire alerted state and suppressed_acked outcome
Follow-ups on top of the salvaged #94692:
- Drop the dead 'reviewed' state and the SQLite CHECK (state validity
lives in INCIDENT_STATES so future slices can add states without a
table rebuild); lifecycle is detected -> alerted -> closed.
- Actually mark incidents 'alerted' after a failure ping reaches
delivery, on both the normal and exception delivery paths.
- Record ack-suppressed runs with a distinct 'suppressed_acked'
delivery outcome (registered in cron_health monitoring) instead of
the ambiguous generic 'suppressed'.
- Drift-skip alerts explicitly bypass the ack gate (they carry the
remediation command and alert once via drift_alerted already).
- Docs: failure-incidents section in the cron guide.
- Tests for the alerted transition + never-resurrect-closed.

Simplify-pass follow-ups on the #87033 fix:
- _gateway_liveness_notice(plural=) authors both wording variants at one
site; removes the exact-substring .replace() that would silently no-op
if the create-path text is ever edited.
- Collapse the operator-precedence-trap conditional in list to a plain
'if jobs' — an empty list has nothing inert and now skips the probe.
- Fix docstring/code mismatch (builder returns gateway_running: True on
the happy path) and drop the dead try/except in
_warn_if_gateway_not_running (the helper never raises).
Follow-ups for the salvaged #93098:
- Move the tri-state liveness heuristic into hermes_cli.cron
(_builtin_gateway_liveness) so the CLI warning and the cronjob tool
share one implementation instead of two drifting copies.
- Surface gateway_running/warning on the list action too — an agent
inspecting jobs in a gateway-less environment has the same silent-
inert-job failure mode (#87033) as create. Empty lists stay quiet.
A cron job can now pin its own reasoning (thinking) effort, independent
of the global agent.reasoning_effort and per-model reasoning_overrides.
Heavy scheduled analyses can run at high while cheap recurring jobs run
at minimal, without touching the fleet-wide default.
- cron/jobs.py: new optional job field, validated at the storage choke
point against the canonical grammar via the shared
hermes_constants.parse_reasoning_effort (spelling-only; capability
clamping stays owned by the provider transports at send time, same as
config-set effort). Empty string clears on update; invalid values
raise ValueError before anything persists. Not a drift-guard axis.
- cron/scheduler.py: _resolve_job_reasoning_config resolves per-job pin
> agent.reasoning_overrides > agent.reasoning_effort at fire time,
after the auth-fallback model swap (the pin is model-independent by
design). A stored value that no longer parses warns and falls back to
config resolution instead of killing the tick.
- tools/cronjob_tools.py: reasoning_effort on BOTH mutation verbs
(create and update), conditional key in _format_job, schema documents
grammar/precedence/transport clamping/clear semantics. Agent-settable,
unlike model/provider pins: it cannot redirect spend to a different
model.
- hermes cron create/edit --reasoning-effort (empty string clears).
- Docs: cron feature page tip + CLI reference rows.
Tests: tests/cron/test_cron_reasoning_effort.py (32) — store contract,
scheduler precedence incl. byte-identical absent-field behavior and
garbage fallback, tool create/update/clear/error paths, schema surface.
On hosted deployments a scheduled fire that cannot be forwarded to the
gateway api_server (dead 8642 listener, gateway down) was invisible
outside gui.log: no execution row is created because the claim never
happens, so `cronjob list` showed a healthy job that silently missed
days of scheduled runs (4 consecutive nightly misses in the field,
diagnosed only by log grep).
Changes:
- cron/jobs.py: note_fire_forward_failure() durably stamps
last_fire_error ({at, detail}) on the job record; mark_job_run clears
it on the next successful run so it always describes current
auto-fire health (mirrors preflight_alerted/drift_alerted).
- hermes_cli/web_routers/cron.py: the dashboard fire webhook stamps the
job on the gateway-unreachable path, best-effort (never disturbs the
503/Retry-After retry contract or the OOF-266 intentional-stop drop).
- tools/cronjob_tools.py: _format_job carries last_fire_error so the
agent-facing cronjob list surfaces it.
- hermes_cli/cron.py: `hermes cron list` prints a red
"Missed scheduled fire" line.
- web/: dashboard CronPage renders the miss; api.ts type updated.
- gateway/run.py: one-time startup warning when an external cron
provider is active but the api_server adapter is not running (the
fire path is dead-on-arrival; most common cause is API_SERVER_KEY
missing from an unsupervised gateway relaunch).
- website/docs: cron doc section on missed fires.
/simplify-code findings on the salvage stack:
- the classify+reclaim+counter block was pasted verbatim into both ticker
loops (_start and _start_multiplex) along with duplicated function-local
imports — extracted _note_tick_failure() next to _backoff_wait_seconds
so both loops share one implementation.
- hermes_cli/cron.py's EMFILE hint reimplemented the text half of
_is_fd_exhaustion with a case-SENSITIVE variation (drift risk) — split
_is_fd_exhaustion_text() out and use it from both.
11 EMFILE tests + 54 provider/ticker tests green; ruff clean.
Follow-ups on the #87796 salvage:
- cron/scheduler.py: drop the _reclaim_fds_best_effort call at tick()'s
lock-failure raise site — the ticker loop's except handler already runs
reclamation once per failed tick, so the raise-site call doubled the
gc.collect() pause on every EMFILE failure.
- cron/scheduler_provider.py: extract the exponential-backoff math
duplicated verbatim in start() and _start_multiplex() into a module-level
_backoff_wait_seconds() helper.
- hermes_cli/cron.py: `hermes cron tick` now reports a propagated OSError
cleanly (exit 1) instead of dumping a traceback — tick() raising on real
lock-acquisition failures is new behavior from this fix.
tick() swallowed a real OSError at tick-lock acquisition as 'another
instance holds the lock', so fd exhaustion (EMFILE/ENFILE) made the
scheduler return 0 — recorded as a successful tick — while no job ever
ran again. Heartbeat and success markers stayed fresh, masking the stall.
- propagate lock-acquisition OSError to the ticker loop (records + backs off)
- detect fd exhaustion, attempt gc.collect() + raise soft nofile limit
- exponential backoff so an exhausted process stops hammering the store
- preserve genuine lock contention (EWOULDBLOCK) silent-skip behavior
- 11 regression tests
CLI parity for the continuity toggle:
- subcommands/cron.py: --continuity on create; --continuity / --no-continuity
tri-state pair on edit (same store_const pattern as --no-agent/--agent)
- cron.py: forwarded to the cronjob tool; created/edited job summaries print
a "Continuity: on" line
- cronjob_tools._format_job: reports continuity as an explicit boolean and
strips the reserved 'self' entry from the reported context_from list
- cron-job.ts: form reader accepts both shapes (raw store record with 'self'
inside context_from, or formatted record with the explicit flag)
- docs: CLI flag examples in the continuity section
E2E (real argparse -> cron_create/cron_edit -> jobs.json in temp HERMES_HOME):
create --continuity stores ['self']; edit --no-continuity clears; edit
--continuity restores; default-off unchanged. 91 cron/tool tests + 16 CLI
cron tests + vitest 10/10 pass.
Poke (poke.com) 'encourages users to review recurring automations that
haven't been acted upon'. Hermes' equivalent pain point is a recurring
cron job that fails run after run: each failure delivers the same one-line
error with no signal that the automation itself needs attention.
- cron/jobs.py: persist a failure_streak counter in mark_job_run —
incremented on agent failure, reset on success; delivery failures don't
count. Back-compat: missing field reads as 0.
- cron/scheduler.py: _failure_streak_nudge() appends a review nudge to the
delivered failure summary once a recurring job's streak reaches
cron.failure_nudge_threshold (default 3, 0 disables). One-shots never
nudge.
- hermes_cli/cron.py: 'hermes cron list' shows '(N failures in a row)' on
failing jobs with streak >= 2.
- docs: new 'Repeated-failure review nudge' section in cron.md.
Tests: 17 passed (TestMarkJobRun + TestFailureStreakNudge); E2E verified
with real cron store in temp HERMES_HOME.
`hermes cron run <job_id>` from a one-shot CLI invocation could
background-dispatch the run onto a daemon thread of the calling process
(when the CLI inherited a gateway/desktop session env and resolved a
session key). The CLI printed "Triggered job: ..." and exited instantly,
killing the runner mid-LLM-call: the async delegation died with
state='unknown' and the job's row in cron/executions.db stayed
status='claimed' forever, blocking every subsequent run of that job.
Two-part fix:
1. hermes_cli/cron.py: `_job_action("run", ...)` declares the delivery
channel stateless (scoped ContextVar set/reset around the call) before
invoking the cron API, so `async_delivery_supported()` gates off
`_try_dispatch_background_run` and the run executes synchronously to
completion in the CLI process — the same behavior `hermes -z` already
gets via declare_stateless_channel().
2. cron/scheduler.py: tick() now periodically invokes
recover_interrupted_executions() (previously only run at scheduler
startup), so execution rows whose exact owner process is provably dead
(pid + process start time check in _owner_is_live) are reaped to
'unknown' by the long-lived gateway ticker without a restart.
Throttled to once per 300s so idle 60s ticks don't pay a ledger
connection every cycle.
Tests: tests/cron/test_dead_owner_claim_reclaim.py covers the dead-owner
reap (real dead pid via a finished subprocess), live-owner rows surviving
the reap, throttle behavior, reap-failure isolation, the CLI stateless
gate (including restoration after the call), and the end-to-end refusal
of background dispatch under a stateless channel.
Fixes#86721
pause_job already sets enabled=false atomically with state/paused_at, but
get_due_jobs only checked enabled — so a contradictory record
(enabled=true + paused_at/state=paused) still fired. That was the 07-30
outage failure mode: list looked frozen, fleet kept merging.
- is_job_runnable / effective_job_state: pause markers gate fire; display
derives from the scheduler-honoured enabled flag so half-paused never
renders as [paused]
- get_due_jobs self-heals enabled=false + logs error on contradiction
- claim_job_for_fire uses is_job_runnable (paused_at counts too)
- list/format paths use effective_job_state
- behavioural tests: pause blocks due fire; half-pause self-disables
- cron/notepad.py: SQLite-backed cron_notepad(job_id, key, value,
updated_at) store in its own profile-local db (cron/notepad.db),
following the executions.py connection/transaction pattern. APIs:
set_note/get_note/delete_note/list_notes/clear_notepad +
render_notepad_section. Documented size caps: 16KB per value,
128-char keys, 64KB per job total; oversized writes raise ValueError.
- cron/scheduler.py: inject non-empty notepads into the job prompt at
the context_from data-injection seam as a clearly-labeled
"Job notepad (persistent across runs)" section that also documents
the CLI write path. Empty notepad renders "" — byte-stable prompts
for jobs that never use the feature.
- hermes_cli/cron.py + hermes_cli/subcommands/cron.py:
`hermes cron notepad <job_id> [get|set|delete|list]` under the
existing cron subcommand tree (no new top-level command, no new
model tool — the agent writes via terminal + CLI).
- tests/cron/test_notepad.py: CRUD, durability, cap enforcement,
prompt injection, byte-stable empty case, read-failure resilience,
CLI handler + dispatch (TDD; watched fail first).
Inspired by: Amp (Sourcegraph) cron notepad (idea-level, proprietary —
zero code).
