The cherry-picked tests predate #85508's honest fallback-chain phrasing
and each other: assertions pinned the old 'exhausted or unavailable'
literal and #83188's no_agent fallback-note behavior, which #77648's
mode gate supersedes (no provider classification at all for no_agent
jobs). Assert the composed contract instead.
`_summarize_cron_failure_for_delivery` classifies a failed job by
substring-matching the error prose — "timed out", "429",
`authenticat|authoriz` — and maps any hit onto a provider-shaped
explanation, without consulting the job's execution mode.
A `no_agent` job IS its script: `run_job` short-circuits it before any
model is reached. Provider timeouts, rate limits, auth errors and
fallback chains are therefore structurally impossible for it, yet those
branches are tested first.
`_run_job_script` reports a timeout as "Script timed out after {n}s:
{path}". That contains "timed out", so a shell script exceeding its
timeout is delivered to chat as:
⚠️ Cron 'x' failed: provider timeout. Fallback chain was exhausted
or unavailable.
for a job that never opened a socket, sending the reader to inspect
model routing while the actual fault is a shell script. "429" or
"authentication" appearing anywhere in a script's output misfires the
same way.
Gate the three provider branches on `not job.get("no_agent")` and let
script jobs fall through to the existing generic cleaner, which already
reports the real error and names the script. No new message text.
The auth branch carries a word-boundary guard so "oauth" and "4015" do
not trip it, which addresses one substring false-positive; gating on
mode removes the remaining class for script jobs.
Tests: the summarizer had no direct coverage — the only test referencing
it patches it out and asserts on its arguments. Adds parametrized cases
pinning both directions: script jobs are never blamed on a provider
(including when their output contains "429" or "authentication"), and
agent-mode jobs keep the existing provider summaries unchanged.

- Widen the scheduler-internal timeout classification to the sibling
TERMINAL_CWD lock-wait TimeoutError (#79768), which also matched the
generic 'timed out' branch and was delivered as a provider timeout.
- Reconcile the drift-guard alert with #72056's lifecycle-aware
remediation: finite one-shots are told to recreate the job, not to
update a consumed one.
- Scrub environment-specific references from comments/docstrings.
The generic failure summarizer caps unrecognized errors at 180 chars,
which cut the drift alert off mid-sentence before the pin command. The
drift branch now formats its own delivery from the guard's full message,
so the one alert the operator gets actually contains the fix.
A fleet-wide inference config change previously produced one 'Skipped to
prevent unintended spend' alert per unpinned job per tick — 40 jobs meant
40 alerts every tick until each was re-pinned (Coatue field report,
2026-08-11). The #44585 guard now reuses the #73506 alert-once shape the
preflight path already established: a persisted drift_alerted bit on the
job record, a [drift_skip:silent] marker on repeat ticks that suppresses
delivery, and the bit clears on the next successful run so a future drift
re-alerts. Only the drift branch consults the bit — every other failure
keeps alerting per tick.
The alert text also now says it is sent once, so operators know the job
stays skipped silently until pinned or restored.
A cron that dies on a provider timeout with no fallback chain configured
now tells the operator exactly how to fix it: `hermes fallback add` for a
personal chain, or the cron.model + cron.model_provider fleet defaults for
operator-managed fleets. The exhausted-chain branch stays terse — the chain
is intact there and no config command applies.
Field-reported: users hitting the empty-chain failure could not self-serve
from the alert text alone.
_summarize_cron_failure_for_delivery() unconditionally said 'Fallback
chain was exhausted or unavailable.' on every provider failure, even
when fallback_providers is empty (the default -- confirmed empty on
both the root and cto profile config.yaml). That phrasing implies a
fallback was attempted and failed, which sent the operator debugging
the wrong thing.
Add _fallback_chain_phrase(): reads the effective chain via
get_fallback_chain(load_config()) and returns 'No fallback chain
configured.' when it's empty, or the original wording when a chain
exists. Fails open to the original wording on any config read error.
The scheduler's own inactivity-watchdog mislabeling (idle-timeout
reported as provider timeout) was already fixed in a prior commit on
this branch; this closes the second half of t_29b8da55.
Data pull requested by the task (grep errors.log across profiles +
root for 'Provider has been unresponsive' + model=, 2026-07-21 to
2026-08-06): 9 stall events total, 5 on claude-sonnet-5, 4 on
claude-haiku-4-5, spread across 6 different cron jobs. No material
haiku-specific instability -- sonnet-5 stalls at least as often on the
cron path in this sample. Reporting per acceptance criteria; not
worth a routing change on this evidence.
Bug 1: relay-fronted Slack in thread-per-message mode stamps each top-level
message's own id as source.thread_id (session KEYING, native thread_ts
parity). Cron origin capture persisted that stamp as durable routing, so
every delivery landed inside the ephemeral thread spawned around the
creation message instead of the top-level conversation. Fix at the source:
_origin_from_env drops a Slack thread id equal to the creation message's
own id (genuine in-thread creations keep theirs). Fire-time repair for
already-persisted jobs: deliver=origin and the explicit-target Slack
re-attach treat an origin thread as stale when the origin chat is the
configured Slack home chat — top-level (or the home target's configured
thread) wins; non-home working threads are preserved.
Bug 2: _preflight_check_delivery and cron_delivery_targets validated
deliver prefixes against get_connected_platforms(), which only sees
natively configured platforms — a relay-only deployment ({relay}) rejected
'slack:CHAT' with 'no gateway credentials configured' although fire-time
routing (resolve_delivery_transport + RelayAdapter.fronts_platform)
delivers it. New gateway.relay.relay_fronted_platforms() (env-derived from
GATEWAY_RELAY_PLATFORMS — the same source that seeds the live adapter's
identity set, so validation and routing cannot disagree) is unioned into
the connected set when the relay is connected. Native topologies keep the
strict credential check unchanged.
Review caught a real gap: action='update' also accepts deliver, and the
tool description explicitly steers agents toward update-over-create — so
a cron-context agent updating a job to deliver='origin' would recreate
exactly the dangling literal-origin shape the create-path resolution
prevents (stored 'origin' on an origin-less job → fire-time home-channel
guessing or silent drop).
Wrap the update site in the same resolver. Semantics follow the create
precedent: in cron context, 'origin' means 'my run's target', resolved
concretely at mutation time; outside cron context updates are
byte-identical to before.
A job created from within a cron run must never store the literal
'origin' delivery target: the creating session is ephemeral, so by fire
time there is no origin to resolve and the scheduler falls back to
guessing a home channel. With agent scheduling enabled
(cron.allow_agent_scheduling), a scheduled agent creating follow-up jobs
would silently produce exactly that dangling shape.
Resolve at create time instead, in cron context only: 'origin' elements
(and an omitted deliver) are replaced with the creating run's concrete
target from the per-run HERMES_CRON_AUTO_DELIVER_* contextvars —
platform:chat_id[:thread_id], or 'local' when the creating run has no
concrete target. Explicit values ('local', 'all', platform:chat_id
targets) pass through verbatim, including inside comma lists. Chat and
CLI creates are byte-identical to before: the resolver is a no-op
outside cron-context sessions (HERMES_CRON_SESSION unset).
Cron-spawned agents have the cronjob toolset unconditionally denied, so
scheduled agents cannot create, tune, or remove jobs even when an
operator wants exactly that (reconciler-style jobs that manage a team's
cron table, follow-up one-shots scheduled from within scheduled work).
The denial is loop-prevention policy, not a security boundary: an agent
with the terminal toolset can already shell out to the CLI, so the
workaround exists but skips every limit and accounting layer.
Add cron.allow_agent_scheduling (config.yaml, default false — byte-exact
current behavior). When enabled, only 'cronjob' leaves the cron-context
denylist; 'messaging' and 'clarify' remain denied as interactivity
constraints, and the user-level agent.disabled_toolsets layering is
unchanged, so a user denylist entry still beats the gate. The cronjob
tool description now states the real policy and the quota bounds instead
of a blanket prohibition.
Cron jobs targeting a relay-fronted logical platform (e.g. Discord behind
the relay connector) failed twice over:
1. Target resolution read only the legacy <PLATFORM>_HOME_CHANNEL env
mirror. The canonical home_channel block that /sethome persists to
config.yaml — the only store that exists in a relay-fronted deployment,
where no native env var is exported — was never consulted, so
deliver='discord' silently resolved to nothing and the job fell back
to local-only.
2. Even with a resolved target, the delivery loop's native
configured/enabled gate rejected the platform ('not configured/enabled')
although resolve_delivery_transport had already produced a live relay
transport fronting it. A relay-fronted platform is deliberately NOT
natively enabled (its credential lives in the connector), so the native
gate must not apply to a relay transport.
Resolution now falls back from the env mirror to
config.get_home_channel(platform) for both chat_id and thread_id (thread
affinity only when the chat id came from the same config block), which
also makes the 'all' routing token pick up relay-fronted platforms. The
delivery gate honours a resolved relay transport, mirroring the
enablement rule resolve_delivery_transport already applied; the standalone
(no-relay) path keeps the historical gate byte-identical.
hermes-cron-tick.service starts without TELEGRAM_HOME_CHANNEL/DISCORD_HOME_CHANNEL
in the unit env; the per-run load_hermes_dotenv reload lived only on the agent
path (after the no_agent short-circuit returns), so every deliver=telegram/all
script job failed with 'no delivery target resolved'. Load the dotenv at the top
of the no_agent branch; override=False keeps the gateway's in-process tick
behavior unchanged.
many tests patched sys.platform or a module's _IS_WINDOWS flag, then
ran on linux ci. the patch selects the branch under test, but the host
does not have the behavior the branch exists for. the test proves the
patch, not the platform. some gated assertions never ran on any host.
this commit adds three markers: linux_only, macos_only, windows_only.
a conftest hook skips a marked test on the other hosts, with a clear
reason. no test fakes a host now. two documented fakes remain
(android/termux, freebsd) because no ci runner exists for them.
each fake site got one of four treatments:
- gate it: the real host supplies the platform; mocks cover real
dependencies only, never host identity
- patch the module's own probe when the subject is the probe's consumer
- assert against the real host when the fake stood in for any non-x host
- delete the patch when it set the value the host already has
bare skipif(sys.platform != ...) guards became markers too. the lane
model skips these on linux and never imports them on windows, so they
ran on no host. platform parametrize tables are now one marked test
per os.
running on real hosts found real errors: a chrome-sandbox failure in
test_gui_command that main hides, and two windows failures fixed here.
the agents.md testing section now documents the policy.
Four fix-forwards from the adversarial post-merge audit of the Aug 7
unreviewed merge batch:
- estop (#81148): is_engaged() now fails SAFE (engaged) on stat errors;
the gateway estop gate lets recognized slash commands and replies owned
by in-flight work (update prompts, clarify, slash-confirm, tool
approvals, running sessions) through instead of consuming them; new
gateway /pause [reason|off] command gives messaging-only operators an
in-band engage/resume path (busy_policy=dispatch so it works mid-run).
- cron monitor mode (#81138): execution-mode invariants (monitor x
no_agent, monitor_script x monitor_url, no_agent-requires-script) now
have ONE owner (_validate_job_mode_invariants) called from BOTH
create_job and update_job, so the create-time invariant can no longer
be silently violated through the update door.
- cron notepad (#81139): remove_job now clears the job's notepad rows
(clear_notepad was dead code -> orphaned KV state forever); clear is
best-effort and no-ops without creating notepad.db.
- delegation batch gate (#81141): template-marker regex narrowed to
multi-word placeholder shapes only (<feature name>, {file_path}) so
generics (Vec<T>), HTML tags, JSON snippets, glob braces and f-string
style no longer reject legitimate batches; duplicate-goal rejection
removed (best-of-N fan-outs are legitimate).
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
- Fix _usage_audit_path() to use _get_hermes_home() instead of hardcoded
Path.home() / '.hermes' (profile-safe resolution, sweeper finding)
- Rewrite skip_background_review tests to exercise finalize_turn() directly
instead of duplicating the guard expression (sweeper finding)
- Fix response_silent audit field to use _is_cron_silence_response()
instead of the buggy SILENT_MARKER substring check it was meant to
replace (simplify-code review finding)
- Remove dead 'model' in locals() guard — model is always in scope
before the try block (simplify-code review finding)
- Extract _stub_agent_for_finalize() helper to eliminate ~40 lines of
copy-pasted agent stubbing in tests (simplify-code review finding)
- Clean up 'Phase 0.5' instrumentation comments
Phase 0.5 of the Hermes Agent token leak mitigation plan: append a single
JSONL line to ~/.hermes/cron/usage_audit.jsonl after every cron LLM
invocation, capturing prompt/completion/total tokens, model, duration_ms,
deliver target, and error (when raised). Read from agent.session_*_tokens
which run_conversation already returns in its result dict.
Without this, we have no measured baseline to attribute token deltas to
subsequent mitigation phases. The plan's hard gate: observability lands
before any mitigation phase.
Writer NEVER raises — wrapped in a single try/except that logs a warning
on any json.dumps / mkdir / open failure so an audit-log bug cannot
break a cron job. Failure-path audit guard via locals() check covers
exceptions that fire before the fire_id is assigned.
No new dependencies, no new env vars (the plan rejected one in v2).
Tests: 7 new unit tests in tests/cron/test_usage_audit_logger.py covering
the success path, missing token info, swallowed writer exception, parent
dir creation, multiple appends, and unicode preservation.

Validate a job's configuration BEFORE any agent machinery is constructed:
- missing provider API key (AuthError from a read-only
resolve_runtime_provider probe; skipped when a fallback_providers chain
is configured, since auth-fallback may rescue the run)
- attached skill not ready (skill_view readiness_status=setup_needed —
missing required env vars / commands / credential files)
- delivery platform unknown or unconnected (deliver=local/origin/all are
never checked; gateway-config load failures fail open)
On a failing check run_job returns a [blocked_config]-marked error without
constructing AIAgent/MCP/etc, so a misconfigured job never burns an LLM
call. run_one_job records last_status='blocked_config' and delivers the
alert exactly ONCE across ticks (persisted preflight_alerted bit — the
alert-once shape from the #73506 dead-pin auto-pause); the next healthy
run clears the marker so a future break re-alerts. Every preflight check
fails open: only an affirmative misconfiguration verdict blocks.
Config: cron.preflight (default true); `cron.preflight: false` restores
the old fail-during-run behavior. Documented in the cron user guide and
config defaults.
mark_job_run gains an optional status= override (unblocked call shape
unchanged) and drops preflight_alerted on any successful run.
Tests: tests/cron/test_preflight_config.py (blocked_config + no agent +
single alert across two ticks, healthy job unaffected, recovery clears
dedup, fallback-chain rescue, opt-out restores old behavior, skill
readiness miss, unknown delivery platform, deliver=local never loads
gateway config). Full tests/cron/ + cronjob tool suite green (525 tests).

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:

Add monitor-mode cron jobs: a cheap monitor source (monitor_script or
monitor_url) runs on every tick BEFORE any agent machinery is built.
Its output is hashed as exact bytes and compared to the hash stored
from the last agent-triggering tick:
- unchanged -> agent run suppressed entirely (no LLM, no delivery);
the tick is recorded as a silent no_change run visible in the
executions ledger doc
- changed -> a MONITOR CHANGE DETECTED block (capped unified diff of
previous vs current output + the new output) is injected into the
prompt via the existing extra_prompt seam, then a normal agent run
- first run -> always runs the agent with a baseline block
- source failure -> delivered as an ERROR alert, never treated as a
change; the stored hash is untouched so recovery to prior output
still suppresses
Implementation:
- cron/monitor.py (new): hash/diff/URL-fetch/state persistence.
monitor_script reuses _run_job_script (same ~/.hermes/scripts/
containment + interpreter rules); monitor_url is a bounded GET
(30s, 256KB, http/https only). Output is exact bytes by design —
scripts should emit stable output (documented).
- cron/jobs.py: additive job fields monitor_script / monitor_url /
monitor_state {last_output_hash, last_changed_at}. JSON job records
need no migration. create-time validation: sources are mutually
exclusive and incompatible with no_agent=True.
- cron/scheduler.py: one tight monitor gate in run_job between the
no_agent short-circuit and the LLM path (outside sibling-lane
regions). State persists in jobs.json + a per-job snapshot file, so
suppression survives scheduler restarts.
- tools/cronjob_tools.py: additive optional monitor_script/monitor_url
params on the cronjob tool (create + update, empty string clears),
path containment validated at the API boundary, surfaced in
_format_job.
- hermes_cli: --monitor-script/--monitor-url on `hermes cron create`
and `hermes cron edit`; `hermes cron list` shows the monitor source
and last-changed time.
Tests (tests/cron/test_monitor_kind.py, TDD): unchanged suppresses,
changed injects diff, first run always runs, hash persists across
module reload (restart), script failure is error-not-change with hash
untouched, create/update validation, tool wiring + path-escape reject.

Follow-up to the salvaged registration contract:
- share one _raise_if_cron_registration_error() helper for the two
byte-identical dashboard 424 except-blocks (web_server + cron router,
via the existing late() seam)
- add endpoint-level 424 coverage for /api/cron/blueprints/instantiate
(previously only the sync worker was tested)
- give chat/CLI surfaces a human-facing user_message() (job name, no
exception class name) and add a recovery hint (pause/resume or update
re-registers via provider reconcile) to the model/REST message
- consolidate five inline provider test doubles into one ABC-subclassing
make_cron_provider conftest factory; the web_server test double now
subclasses CronScheduler so an ABC rename fails loudly
- narrow the wrapper facade to keyword-only (**kwargs) and route the
tool's partial-failure return through tool_error()
Follow-up hardening on the salvaged #80687 shrink-merge guard, folding in
the best part of the competing #80703 (credit: @JoaoMarcos44):
- Stat-stamp fast path: load_jobs() inside a _jobs_lock() section records
jobs.json's (mtime_ns, size, ino) BEFORE reading; the save-path merge
and the post-stage verify skip their full read+parse when the stamp
still matches. The healthy no-race save (every mark_job_run /
claim_dispatch / heartbeat / advance_next_runs tick persist) now costs
one stat() instead of up to two full JSON parses.
- Fail-safe stamp discipline: the stamp is captured pre-read (a sibling
racing the load leaves it older than disk -> mismatch -> merge runs),
includes st_ino (mkstemp+rename always allocates a new inode, so
coarse-mtime filesystems cannot false-match), resets on section
entry/exit, and is INVALIDATED - never refreshed - after any write in
the section (a refresh would let a nested create_job be clobbered by
an outer caller's stale payload; probe-verified both directions).
- _merge_unexpected_disk_jobs no longer mutates the caller's list in
place - it returns a new list when anything was recovered, and logs the
recovered ids.
- The tolerant read cascade (utf-8-sig + strict=False fallback) is
factored into one shared _parse_jobs_file used by both load_jobs and
_peek_jobs_unlocked, so future encoding/shape fixes land once. The
peek's repair-free re-entrancy contract is now documented - a repairing
read on the save path would recurse through _save_jobs_unlocked (the
exact defect the stamp-reconcile approach in #80703 had).
4 new regression tests (fast path, no-mutation, corrupt-file save,

Follow-up hardening on top of the salvaged #80809 watchdog, porting the
locked state-machine design from #75301 (credit: @Zeraphim):
- All lifecycle transitions (stale/cancelled/done) now happen under
request_client_lock. A user or monitor interrupt marks the request
'cancelled' so a racing stale timer can no longer misclassify the kill
as provider staleness and feed a false +1 into the #58962 cross-turn
circuit breaker.
- 'done' is set under the lock on completion, so a late timer callback
that lost the race to a successful response is inert instead of
leaving a spurious streak=1 behind the reset.
- Registration race closed: if the budget expires while the client is
still being constructed, _make_client aborts the freshly-registered
client and fails the call with a retryable TimeoutError instead of
opening a brand-new socket after the only watchdog already fired.
- _resolve_direct_stale_timeout now fails closed: a raising resolver
propagates (same as the worker path) instead of being swallowed into
an infinite budget that would silently disarm the watchdog and
reinstate the very hang #80759 is about.
4 new regression tests, each verified to fail against the pre-fix
watchdog implementation.

Cron turns and delegated children are routed onto direct_api_call, which
ran the request inline with no stale detector. The abort plumbing was
registered but nothing ever invoked it, so a provider that accepted the
request and then went silent — connection held open, zero bytes, no
error — hung the run until an external actor killed it, which also
orphaned the execution row. The httpx read timeout is not a usable bound
(1800s default, and this failure mode never trips it), and the job-level
inactivity monitor was observed not to fire.
Arm a watchdog timer on the same budget the interrupt worker's poll loop
uses, so these turns get exactly the patience every other non-streaming
request already gets. On expiry it only aborts the in-flight sockets
through the already-registered hook — it never issues a request, so the
inline / no-worker property that fixes the nested-pool deadlock is
preserved — bumps the cross-turn stale circuit breaker, and surfaces a
retryable TimeoutError so the outer loop reconnects on a fresh pool.

Salvaged from PR #57342 by @liuhao1024 (with the injection-scan half
from PR #57360 by @ghedeselmabot): cronjob(action='run', prompt=...)
silently discarded the prompt argument — per-run context never
reached the spawned cron session.
The prompt is now threaded as extra_prompt through the whole chain
(cronjob run action → _try_dispatch_background_run/_execute_job_now →
_run_claimed_job → run_one_job → run_job → _build_job_prompt) and
appended to the stored prompt under a '## Run Context' header for
that single fire only — never persisted to the job definition. It
passes the same strict _scan_cron_prompt injection scan as stored
prompts before firing, and works identically on the background and
sync fallback paths.
Test fakes across tests/cron/ updated to accept the new kwargs
(sibling-test blast radius from the signature change).

Pins the scheduler-boundary contract: extra_prompt is appended under
'## Run Context', does not mutate job['prompt'], and the header is
absent when extra_prompt is omitted.
Addresses review feedback from harjothkhara on PR #57342.
3-reviewer simplify pass (reuse/quality/efficiency) findings:
- cron/scheduler.py _run_job_script: the ORIGINAL that
lifecycle_guard._resolve_script_path documents mirroring had the exact
same unguarded expanduser() — a NUL-bearing script value survives
creation (the guard treats it as nothing-to-scan) and crashed the
scheduler at fire time with ValueError instead of a clean job failure.
Same ingestion contract applied; regression test added.
- lifecycle_guard._resolve_script_path: get_hermes_home() -> Path.home()
raises RuntimeError when neither HERMES_HOME nor HOME resolves
(arbitrary-UID containers); the cron entry point called it bare.
Caught -> None; totality test added.
- terminal_tool: stale 'cat ...' docstring updated to the bounded
head -c form.
- lifecycle_guard: dead 'script_text and' condition dropped (guarded by
'if not script_text: continue' directly above).
Efficiency reviewer: no material findings (measured — encode/expand
costs negligible vs walk I/O, no timing regression vs base).
Cron agents are constructed with skip_memory=True, so the memory
backend is not initialised — exposing the memory tool only gives the
model an unbacked tool that fails at runtime with 'Memory is not
available.' Add 'memory' to _resolve_cron_disabled_toolsets() so the
tool is stripped from the schema before the model can call it.
Fixes#38129.

The AST invariant only matched `env["HERMES_KANBAN_X"] = ...` subscript
assignments, so a future dispatcher var added via `env.update({...})`,
`env.setdefault(...)`, or an annotated subscript would have slipped past
the guard and leaked into cron sessions unnoticed.
None of those shapes exist in _default_spawn today; this is about the
guard staying trustworthy as that function evolves.
Verified by injecting an unregistered var into _default_spawn one shape at
a time and requiring the guard to fail: subscript assign, annotated
assign, update(dict literal), setdefault(literal), and update(kwarg) are
all detected. Source restored byte-identical after probing.
tests/cron/ 410 passed; ruff clean.
A kanban worker that fires a cron job in-process no longer leaks its task
identity into the cron agent.
The worker is a normal `hermes chat -q` CLI agent whose default toolset
includes `cronjob`, running with HERMES_KANBAN_TASK legitimately set in its
own environment. `cronjob(action="run")` calls run_one_job() -> run_job()
in that same process, so the cron AIAgent was misidentified as that worker:
kanban toolset force-added, kanban-worker protocol injected into its system
prompt, and kanban_complete defaulting task_id to $HERMES_KANBAN_TASK --
letting an unrelated cron job close the worker's task and overwrite real
results.
Fixed with a ContextVar (`non_dispatcher_owned_context`), not by clearing
os.environ. The env is process-global and shared with three concurrent
readers that all need the real values:
* the worker's own claim heartbeat -- run_agent._touch_activity ->
heartbeat_current_worker_from_env reads TASK/CLAIM_LOCK/RUN_ID, and the
cron-run heartbeat thread drives it every 10s. Clearing them silently
no-ops the heartbeat, so after DEFAULT_CLAIM_TTL_SECONDS (15 min) the
dispatcher reclaims a task whose worker is still alive and re-dispatches
it -- the same duplicate-work failure from the other direction.
* the gateway's kanban watchers, which do their own HERMES_KANBAN_BOARD
save/restore around a slow decompose_task() LLM call.
* concurrent cron jobs, which take a *shared* read lock
(_terminal_cwd_lock.acquire_read) and so interleave: job A clears, job B
snapshots empty, A restores, B clears and its restore no-ops -- the
worker's identity is destroyed permanently.
`is_dispatcher_owned_worker_context()` is now the single predicate every
HERMES_KANBAN_* identity gate consults before trusting those vars. It also
closes a pre-existing gap in agent/skill_utils.py, which read the vars
without consulting the delegate_task ContextVar at all; the `kanban` verdict
additionally bypasses _ENV_DETECT_CACHE, since a context-dependent answer
must not be memoized process-wide.
HERMES_KANBAN_BOARD/DB/WORKSPACES_ROOT are left untouched, so the #20074
board pin and the dispatcher's path overrides keep working.
Tests: 18 new, including thread-isolation, concurrent-cron-jobs, and an AST
invariant over _default_spawn that fails if the dispatcher gains a var that
is neither identity-gated nor explicitly classified behaviour-only. All six
mutations are caught, including one that reintroduces the os.environ clear.
tests/cron/ + kanban suites 440 passed; model_tools/skill_utils/boards 63
passed; ruff clean.

Add activity_hb.join(timeout=2.0) after activity_hb_stop.set() in
direct_api_call's finally block so the heartbeat thread is deterministically
stopped before client teardown. Add test verifying no stray _touch_activity
fires after direct_api_call raises an exception.
Follow-up to PR #78548 by @xxxigm.
Top-level delegate_task runs in the background, and the 450s progress-stall
monitor only sees api_call_count / tool / last_activity_ts. Subagents use
non-streaming direct_api_call, which previously touched activity once and then
went silent — so a healthy local GGUF / long-prefill wait looked frozen and
was interrupted around ~450s as "Operation interrupted: waiting for model
response", even when child_timeout_seconds was raised. Refresh activity while
the inline request is open, and treat last_activity_ts advances as sync
heartbeat progress too.
Re-derivation of #33612 by @LeonSGP43 onto the rewritten scheduler (the
original is 10,692 commits behind; its tick() no longer exists in that
shape, so this is a fresh minimal fix crediting the PR's idea).
The gateway's built-in ticker calls tick(verbose=False) every 60s. The
idle early-return was gated on 'verbose and not due_jobs', so idle
GATEWAY ticks fell through to load_config() + worker-pool resolution
every minute. Return early on ANY idle tick; keep the post-tick MCP
orphan sweep (main intentionally reaps orphaned stdio children on idle
ticks).
3 new tests; mutation-checked (restoring the verbose-gated guard fails
the config-skip test). 66 scheduler tests green.
mark_job_run popped a finite one-shot from jobs.json the moment its
repeat limit was reached and returned early — discarding the
last_status / last_error / last_delivery_error it had just written.
Every finished one-shot vanished from `cronjob action=list` with no
inspectable record, and a delivery failure (agent succeeded, platform
send failed) was silently thrown away with it.
Changes:
- mark_job_run now retires a limit-reached one-shot as a terminal
record (state="completed", enabled=False, next_run_at=None) —
mirroring the existing next_run_at-is-None terminal branch — so the
final status and any delivery error persist and surface in the
cronjob tool's list output (which already emits last_delivery_error
and defaults to include_disabled=True).
- claim_dispatch's stale-job cleanup marks already-ran jobs completed
instead of popping them; genuinely wedged claims (last_run_at never
written) are still removed with the operator-visible diagnostic.
- Retention sweep in the due scan prunes completed one-shot records
older than cron.completed_retention_days (default 7; non-positive
disables) so jobs.json cannot grow unboundedly. Recurring jobs and
non-terminal one-shots are never candidates.
Tests: completion retains record + delivery error, list surfaces it,
completed jobs never re-dispatch, sweep prunes old / keeps recent /
ignores recurring / honors the disable knob; recurring lifecycle
unchanged.
Replace the process-global HERMES_CRON_SESSION env var with a per-session
ContextVar so a cron tick in the gateway process cannot leak into unrelated
live gateway/API/TUI turns. The cron scheduler now sets the ContextVar
inside the job's try/finally scope and resets it on cleanup. Gateway, API
server, ACP adapter, and TUI gateway all pass cron_session='' to explicitly
mark their sessions as non-cron, masking any stale process env.

Closes#37968
The scheduler's pre-dispatch loop called advance_next_run per due job —
one full load_jobs() + one full save_jobs() of the jobs file each — so
N due jobs cost N reads + N writes of the whole file (gateway-restart
catch-up or co-scheduled bursts). advance_next_runs() does one load +
at most one save for the whole due set with identical per-job semantics;
advance_next_run() is now a thin wrapper over it.
Measured (50 due recurring jobs, real jobs file): 107.9 ms -> 2.5 ms
(45x; 50 loads + 50 saves -> 1 + 1).
Tests: batch advances recurring and skips one-shots, single load + save
I/O pin (fails pre-fix — no such function), no save when nothing
advances, and per-job wrapper semantics unchanged. Related: #60946 and
#75833 both restructure this loop's call site for correctness — neither
addresses the I/O cost, and this batch primitive composes with either
dispatch design; happy to rebase onto whichever lands first.
