+Cron turns (and delegated children) are routed by ``should_use_direct_api_call``

+the abort plumbing was registered but nothing ever invoked it. A provider that

+the already-registered abort hook, surfaces a retryable ``TimeoutError`` (never
+``InterruptedError``), feeds the cross-turn stale circuit breaker, and stays
+out of the way of a healthy call. They also pin #85252: the keepalive httpx
+client uses ``read=None``, so a stranger-thread abort that finds no sockets
+must not leave the call unbounded — ``direct_api_call`` injects a per-call
+read timeout matching the stale budget as a hard backstop.

+"""Regression tests for #87644 — cron scheduler silently stalls after EMFILE.
+
+Three fixes under test:
+
+1. ``tick()`` no longer swallows a real ``OSError`` at tick-lock acquisition as
+   "another instance holds the lock".  An EMFILE/ENFILE (fd exhaustion) on
+   ``open(.tick.lock)`` previously made ``tick()`` return 0 — which the ticker
+   loop recorded as a *successful* tick and cleared the error — so the
+   scheduler looked perfectly healthy (heartbeat + success markers fresh)
+   while no job ever ran again.  Now the failure propagates to the ticker
+   loop, which records it and backs off.
+
+2. The ticker loop detects fd exhaustion (EMFILE/ENFILE/"Too many open
+   files"), attempts best-effort fd reclamation (``gc.collect()`` + raising
+   the soft nofile limit), and applies exponential backoff so an exhausted
+   process stops hammering the store every 60s.  Once FDs free up, the next
+   tick succeeds and the backoff resets — the scheduler self-heals without a
+   gateway restart.
+
+3. Genuine lock contention (EWOULDBLOCK/EAGAIN on flock) still skips the tick
+   silently — that behavior is preserved.

+"""_summarize_cron_failure_for_delivery must not mislabel the scheduler's own
+inactivity-timeout abort as a provider/fallback-chain failure, and must not
+claim a fallback chain was "exhausted" when none is configured.
+
+Field-reported regression: a stuck `terminal`
+tool call tripped the 600s cron inactivity watchdog. The TimeoutError raised
+by the watchdog contains the substring "limit 600s" and its message reads
+"idle for 1239s (limit 600s)" -- no provider or fallback chain was ever
+involved -- but the old branch order matched the generic "timed out"/"timeout"
+substring check before any inactivity-specific check existed, so the operator
+saw "provider timeout. Fallback chain was exhausted or unavailable." for a
+failure that had nothing to do with either.
+
+Second bug bundled into the same fix: even on a *genuine* provider failure,
+"Fallback chain was exhausted or unavailable." fired unconditionally --
+regardless of whether fallback_providers was ever configured. Most installs
+have fallback_providers: [], so the message always implied an
+attempted-and-failed fallback that never existed. _fallback_chain_phrase() now checks the effective chain
+via get_fallback_chain() and reports "No fallback chain configured." when

+"""Cron sessions must not inherit a kanban worker's dispatcher identity.
+
+A cron job can be fired *in-process* from a kanban worker: the worker is a
+normal ``hermes chat -q`` CLI agent (its default toolset includes ``cronjob``)
+running with ``HERMES_KANBAN_TASK`` legitimately set in its own environment,
+and ``cronjob(action="run")`` calls ``run_one_job()`` -> ``run_job()`` in that
+same process.
+
+Without isolation the cron ``AIAgent`` is misidentified as that worker: the
+kanban toolset is force-added, the kanban-worker protocol is injected into its
+system prompt, and ``kanban_complete`` defaults ``task_id`` to
+``$HERMES_KANBAN_TASK`` — letting an unrelated cron job close the worker's task
+and overwrite real results.
+
+The isolation is a **ContextVar**, deliberately not an ``os.environ`` clear:
+``os.environ`` is process-global and shared with
+
+  * the worker's own claim heartbeat (``run_agent._touch_activity`` ->
+    ``heartbeat_current_worker_from_env``), which would starve and let the
+    dispatcher reclaim a task whose worker is still alive;
+  * the gateway's kanban watchers, which do their own board save/restore;
+  * concurrent cron jobs on the parallel pool, which take a *shared* read lock
+    and can interleave one another's snapshot/restore.
+
+So these tests assert both that the identity is hidden AND that the environment
+is left completely untouched.

+A ``no_agent`` job fired, the scheduler logged

+nothing — no message row, no delivery obligation. The log line was not
+evidence of a send:
+
+* the silence-narration filter returns ``{"success": True, "delivered": False}``
+  (a successful *drop*), and the normalization block read only ``success``;
+* an empty payload skipped the send entirely and still fell into the

+* the log line named the chat but not the lane, so a wrong-thread delivery and
+  a phantom one look identical after the fact.

+Design intent (Teknium, June 2026): a profile's cron jobs both LIVE in that

+- Storage: a job created under profile ``coder`` writes to

+- Execution: the profile-scoped gateway's in-process ticker resolves the

+
+This is the opposite direction from the (reverted) #50112/#32091 "anchor at the

+one store and runs them under whatever HERMES_HOME the ticker happens to have —

+"""Provider-drift fail-closed guard for cron jobs (#44585).
+
+Background: an UNPINNED cron job follows the global default provider. If that
+global state is changed (e.g. a temporary switch to a paid provider like
+nous/claude-fable-5), the job would silently inherit it on its next tick and
+spend real money — the $7.73 incident.
+
+The fix has two halves:
+  - create_job() snapshots the provider resolution WOULD pick at creation into
+    job["provider_snapshot"] (only for unpinned, agent-backed jobs).
+  - run_job() fails closed when an unpinned job's CURRENTLY-resolved provider
+    differs from that snapshot: it skips the run, makes no paid call, and
+    delivers a loud actionable error.
+
+These tests exercise the full run_job path (real imports, mocked AIAgent +
+resolve_runtime_provider against a temp HERMES_HOME) and the create_job
+snapshot capture. They are load-bearing: without the guard, cases (b) call the
+agent and "succeed" instead of failing closed.

+"""Cron thread-seed must key EXACTLY like the reply that will continue it.
+
+Live incident (Alice, 2026-08-20 01:08, job 8e21a957b77b): the continuable
+cron thread seed created its session row with chat_type="thread", but a
+Slack DM thread reply arrives with chat_type="dm" — build_session_key puts
+them in different rows (agent:main:slack:thread:D...:<ts> vs
+agent:main:slack:dm:D...:<ts>), so the user's reply hit a session that had
+never seen the brief. Channels are unaffected (channel thread replies carry
+chat_type="thread"); the DM lane is the unswept sibling of the flat-seed
+is_dm fix (dcca9d8cfe).
+
+Contract under test: the KEY of the seeded session equals the KEY the
+user's in-thread reply will build. Asserting on build_session_key output —
+not on SessionSource field shapes — pins the end-to-end contract.

+"""Timezone-migration silent misfire on the cron fire path.
+
+Production incident: after upgrading from a build that scheduled in UTC to
+one that honours the profile timezone (Europe/Brussels), daily cron jobs
+stopped running. Their ``jobs.json`` rows still held pre-migration instants
+like ``2026-09-02T04:00:00+00:00`` for expr ``0 4 * * *``. ``_ensure_aware``
+normalizes that to ``06:00+02``, which ``0 4 * * *`` excludes, so the
+stale-expression guard (#93049) classified it as a direct ``jobs.json`` edit,
+logged exactly that, and re-anchored to tomorrow WITHOUT firing — the due
+occurrence vanished with no failure anywhere.
+
+The fix classifies the mismatch instead of assuming an edit: an instant whose
+own wall clock is a legal occurrence, and which only left the lattice because
+normalization changed its offset, is a representation migration and fires.
+
+These exercise the real store against a temp ``HERMES_HOME`` (no mocks) per
+the E2E-over-mocks discipline for file-touching code.

+"""Dead-owner cron claim reclaim + one-shot CLI `cron run` sync gate (#86721).
+
+A one-shot ``hermes cron run <job_id>`` used to background-dispatch the run
+onto a daemon thread of the calling process when the CLI inherited a
+gateway/desktop session env. The process exited immediately, the runner died
+mid-LLM-call, and the job's execution row stayed ``claimed`` forever —
+blocking every future run.
+
+Two-part fix under test here:
+
+1. ``hermes_cli.cron._job_action("run", ...)`` declares the channel stateless
+   before invoking the cron API, so the background-dispatch path is gated off
+   and the run executes synchronously to completion in the CLI process.
+2. ``cron.scheduler.tick`` periodically reaps execution rows whose owner
+   process is provably dead (``recover_interrupted_executions``), so a stale
+   ``claimed`` row from a crashed/exited owner auto-clears without a gateway
+   restart.

+"""RED-first regression test for the cron in-flight claim leak (t_27b59583).
+
+The leak
+--------
+``cron/scheduler.py`` tracks in-flight cron jobs in the module-level
+``_running_job_ids`` set. ``_submit_with_guard`` adds a job id BEFORE the
+future that owns its release exists: everything between the add and
+``pool.submit`` — ``create_execution``, ``contextvars.copy_context()``, and
+once running, the whole pre-future body of ``run_one_job`` (SessionDB
+construction around L3150-3161, agent import/build, config load) — has no
+``finally`` that discards the id. If any of it throws or hangs, the release
+path in ``_run_and_release``'s ``finally`` never runs. Every later tick then
+short-circuits with ``cron.scheduler: Job '<x>' already running — skipping``
+with no ``last_error``, no failure counter, and no alert, until the whole
+gateway process restarts (incident: jarvis ``board-pm-triage-*`` jobs,
+2026-08-02).
+
+This file is committed BEFORE the fix (red-first). Against the unfixed
+scheduler these tests MUST FAIL: the stale id is never released, so the
+primary assertion (``job_id not in get_running_job_ids()`` after a tick)
+fails. The implementation task (t_3778a491) makes them pass by adding the
+bounded stale-entry guard: on each tick, a claim older than
+``max(2 * interval, floor)`` with no live future is force-released, logged
+with a countable ``cron.inflight.forced_release`` signal, and surfaced via
+``mark_job_run(..., success=False, error=...)`` as ``last_error``.
+
+Design notes
+------------
+- The job store persists ``schedule`` as an already-parsed DICT
+  (``{"kind": "interval", "minutes": N}``), not the string form
+  ``parse_schedule`` consumes — the fixtures use the persisted dict shape.
+- The guard's age bookkeeping (``_running_since`` / ``_running_futures`` /
+  ``get_inflight_guard_stats``) does not exist yet on the unfixed scheduler.
+  The helpers reference it defensively (``getattr``/``hasattr``) so the SAME
+  file runs cleanly against both the red (unfixed) and the green (fixed)
+  implementation; the leak simulation is identical either way — an id in
+  ``_running_job_ids`` with no future ever installed.

+"""Regression test for the jobs.json cross-process lock.

+Background: ``hermes cron pause`` runs in its own process (CLI → cronjob tool →
+``pause_job`` → ``update_job`` → ``save_jobs``), entirely separate from the
+gateway process that also writes ``jobs.json`` (``mark_job_run`` /
+``advance_next_run`` / due-fast-forward). The module's ``threading.Lock`` only
+serializes writers *inside one process*, so a CLI pause issued while the gateway
+was live could be silently lost to a concurrent gateway write — the job kept
+firing even though the CLI reported "Paused".
+
+``_jobs_lock()`` closes that gap with a short-held cross-process advisory file
+lock. This test proves the lock actually excludes a *separate process*, which an
+in-process ``threading.Lock`` cannot do.

+   while returning ``success: True``. ``_deliver_result`` only checks

+   delivery error, text delivered, file gone.
+
+2. LIVE-ADAPTER LANE SWALLOWS MEDIA FAILURES: ``_send_media_via_adapter``
+   logs failed/skipped sends at WARNING and returns None — the caller
+   cannot surface them into delivery_errors either.
+
+3. MEDIA-POLICY ENV BRIDGE IS GATEWAY-ONLY: ``gateway.strict`` /

+   are exported to the env vars ``validate_media_delivery_path`` reads ONLY

+"""Mirror eligibility for origin-fallback and explicit cron delivery targets.
+
+Field report (enterprise, 2026-08-17): `cron.mirror_delivery: true` with
+`deliver: origin` delivered the brief to Slack but never appended it to the
+reply-facing gateway session, so a user reply hit a session with no context.
+
+Root cause: the job was created by a provisioning script, so it carries no
+captured origin. `deliver: origin` falls back to the home channel — the
+user's actual conversation — but `_target_matches_origin` returns False for
+an empty origin, so the mirror and the in_channel seed never fire. The June
+origin-scoping refactor (c06ceb3232) correctly excluded broadcasts, but the
+origin-FALLBACK target is not a broadcast: it is the best available stand-in
+for the user's primary conversation.
+
+Design under test:
+- Delivery targets carry a `mirror_eligibility` tag set at resolution time:
+  * origin match            -> eligible (unchanged)
+  * origin-fallback (deliver=origin, no origin) -> eligible (NEW)
+  * explicit platform:chat  -> eligible ONLY with per-job attach_to_session
+    (NEW, opt-in; the global flag never activates explicit targets)
+  * `all` / bare-platform expansion -> never eligible (unchanged invariant)
+- Dedup across tokens (e.g. "origin,all" hitting the same chat) OR-merges
+  eligibility so token order cannot strip it.
+- The in_channel flat-session seed requires a DM-shaped target or a known
+  user_id: group-channel session keys are user-isolated, and a seed without
+  user_id would create an orphan session no reply ever resolves to.

+"""Regression tests for #86522 — one-shot run_claim cleared on dispatch failure.
+
+``get_due_jobs`` stamps a ``run_claim`` on one-shot jobs before returning them
+as due (#59229); ``mark_job_run`` clears it on completion.  When dispatch
+itself fails (interpreter shutdown, execution-creation error, executor submit
+error) the job never reaches ``mark_job_run`` and the stale claim blocked
+re-dispatch until the TTL expired (default 30 min) — a precisely-timed
+one-shot reminder arrived up to 30 minutes late with no error surfaced.
+
+The fix (salvaged from PR #87591 by @RelaxJonh) adds
+``cron.jobs.clear_run_claim`` and calls it on all three ``_submit_with_guard``
+early-exit paths, wrapped best-effort so a failing store can never crash the
+tick these paths exist to protect.

+"""Deterministic reproduction of the recurring-cron EAGAIN in-memory wedge (t_8b5480b3).
+
+Scenario modelled on the 2026-08-14 incident: a recurring no_agent interval job
+whose script subprocess raises EAGAIN ([Errno 11] Resource temporarily
+unavailable) during a substrate thread-exhaustion spike. After the failure is
+recorded (terminal 'failed' execution row), the job must be re-dispatched on
+the NEXT tick once the substrate recovers — with no force-run.
+
+SCOPE NOTE (honest): this file exercises the in-memory EAGAIN-release class —
+the claim taken by ``_submit_with_guard`` is released when the submit/init
+path fails, so the NEXT tick re-dispatches. It passes on unfixed base because
+a terminal ``failed`` execution row does not itself suppress a recurring job's
+next due fire; that is pre-existing behavior, not the fix. The persisted-state
+(restart-surviving) half of the incident — a recurring job whose persisted
+``last_status=error`` and ``next_run_at`` parked in the future is never
+re-dispatched without force-run/resume — is covered by
+``test_recurring_persisted_error_recovery.py``, which provides the clean
+behavioral RED (unfixed: no execution) / GREEN (fixed: re-dispatched) for the
+new recovery path.
+
+This file drives the REAL `tick()` end-to-end against a throwaway HERMES_HOME:
+  tick 1 -> script EAGAINs (subprocess.run raises OSError 11) -> failed exec row
+  tick 2 -> substrate recovered (script runs clean) -> job MUST fire again

+"""Persisted-state stale-error recovery for recurring cron jobs (t_8b5480b3).
+
+The 2026-08-14 incident (t_20e23f84): 4 recurring no_agent interval jobs
+EAGAIN-failed at 12:50 and then recorded ZERO executions for ~1h47m (~9 missed
+cycles) even after the substrate recovered, and the wedge SURVIVED a gateway
+restart.  The in-memory stale-claim sweep (cron/scheduler.py, t_3778a491)
+heals a leaked `_running_job_ids` claim in-process, but that is only the
+in-process half.  A recurring job whose *persisted* state shows
+`last_status == "error"` and whose `next_run_at` was re-armed into the future
+by `mark_job_run` is invisible to the in-memory sweep: it is not in the
+running set (nothing force-releases it) and it is not due (so `get_due_jobs`
+never returns it).  It just sits — exactly the restart-surviving symptom
+documented in the incident.
+
+This recovery (cron/jobs.py `_get_due_jobs_locked`) re-arms `next_run_at` to
+now for a recurring job that:
+  * is in a persisted `last_status == "error"` state, AND
+  * has NOT re-fired within a full cadence (`last_run_at` older than
+    cadence + grace — so it is NOT a normal transient-error retry that will
+    fire on its own soon), AND
+  * is not currently running in this process.
+
+The scheduler then re-dispatches it on the next tick WITHOUT force-run/resume
+— the built-in equivalent of mech_red_guard's `cron resume`.
+
+Deterministic RED/GREEN: on unfixed code the wedged job is left untouched (no
+execution row, no re-dispatch); with the recovery it re-fires and completes.

+"""Deterministic reproduction of the recurring-cron wedge (t_8b5480b3) — RED/GREEN.
+
+The 2026-08-14 incident (t_20e23f84): 4 recurring no_agent interval jobs
+EAGAIN-failed at 12:50:05 and then recorded ZERO executions for ~1h47m while
+the scheduler ticked normally and fired 100+ other jobs — wedged in a
+non-dispatch state that even survived a gateway restart, cleared only by a
+manual force-run (`hermes cron run <id>`).
+
+Root cause class (t_3778a491, the SAME symptom on 2026-08-02): `_submit_with_guard`
+adds a job id to the in-memory `_running_job_ids` set BEFORE the future that
+owns its release exists. Anything that hangs or dies between the add and
+`pool.submit` (documented case: EAGAIN thread exhaustion on a substrate spike,
+or a wedged SessionDB.__init__ on a stale sqlite flock) leaks the claim. Every
+later tick short-circuits with "already running — skipping" silently — no
+execution row, no last_error, no counter — so the job is due-but-never-dispatched.
+
+The live deployment (origin/main) does NOT contain the t_3778a491 in-flight
+stale-claim sweep, so the wedge class is still live.
+
+This file drives the REAL `tick()` and asserts the fix's contract:
+  RED  (unfixed): a stale in-flight claim is never released by tick → the
+       wedge reproduces deterministically (job stays in the running set, no
+       execution, no re-dispatch without force-run).
+  GREEN (fixed):  the same stale claim is force-released by the next tick
+       (cron.inflight.forced_release) and the job re-fires — no gateway
+       restart, no force-run needed — and 2 consecutive auto-fires work.

+"""Regression tests for MCP server availability in cron jobs.
+
+Background
+==========
+``cron/scheduler.py:run_job()`` constructs ``AIAgent(...)`` directly without
+calling ``discover_mcp_tools()`` — the initialization that CLI and gateway
+paths do at startup. Cron jobs therefore never saw any MCP tools from
+``mcp_servers`` in config.yaml. See #4219.
+
+The fix inserts ``discover_mcp_tools()`` before the ``AIAgent(...)`` call,
+wrapped in try/except so a broken MCP server can't kill an otherwise
+working cron job. ``discover_mcp_tools`` is idempotent — subsequent ticks
+short-circuit on already-connected servers.

+"""Regression coverage for #58720 / #55924 — cron scheduling races
+interpreter finalization.
+
+When the gateway tears down (SIGTERM from ``hermes update`` /
+``hermes gateway stop`` / systemd restart, or an OOM-kill), a cron tick can
+still fire. Once the Python interpreter is finalizing, ``concurrent.futures``
+refuses new work with ``RuntimeError: cannot schedule new futures after
+interpreter shutdown`` and asyncio's default executor is gone. The cron
+delivery + dispatch paths used to hit that unguarded, crashing the tick and
+spraying a traceback into ``errors.log`` on every restart-race.
+
+The fix adds ``_interpreter_shutting_down()`` and guards the scheduling
+sites so they skip gracefully with a warning instead of raising.

+"""Regression test for a hung SessionDB() init permanently wedging a cron job.
+
+Real-world incident: a cron job's ``SessionDB()`` construction inside
+``run_job`` blocked forever (a wedged sqlite3.connect against state.db, no
+other process holding a competing lock by the time it was diagnosed). Because
+that call had no timeout of its own — unlike the agent's run_conversation,
+which is already bounded by HERMES_CRON_TIMEOUT — the worker thread submitted
+by ``_submit_with_guard`` never returned. Its ``finally`` block, which is the
+only thing that discards the job ID from ``_running_job_ids``, never ran.
+Every later tick logged "already running — skipping" and the job never fired
+again until the whole gateway process was restarted days later.
+
+These tests prove ``run_job`` now bounds the SessionDB init with its own
+timeout (HERMES_CRON_SESSION_DB_TIMEOUT, default 10s) so a hang there can
+never again wedge the job past that bound, and — end to end — that the
+dispatch guard is released and the job becomes dispatchable again afterward.
+
+Assertions capture the timeout passed to ``Future.result(timeout=...)`` (and
+optionally force an immediate ``TimeoutError``) — no wall-clock waits, so the
+suite stays free of timing flakes under parallel load.

+"""Regression tests for #60703 — cron ticker silently stalls after gateway restart.
+
+Three fixes under test:
+
+1. ``_jobs_lock()`` bounds its cross-process flock: when another process holds
+   ``.jobs.lock`` indefinitely, acquisition times out, logs at ERROR, and falls
+   through to in-process-only locking — instead of blocking the calling thread
+   (and, transitively, the cron ticker heartbeat) forever.
+
+2. Claim freshness checks are bounded on both sides (``0 <= age < ttl``): a
+   ``fire_claim``/``run_claim`` stamped in the FUTURE (clock/TZ skew across a
+   restart) is treated as stale/overwritable, not eternally fresh.
+
+3. ``_execute_job_now`` no longer mislabels paused/disabled/missing jobs as
+   "already being fired".
