When a cron job fires at 13:00:00.014 and completes at 13:00:00.021,
computeNextRunAtMs was flooring nowMs to 13:00:00.000 and asking croner
for the next occurrence from that exact boundary. Croner could return
13:00:00.000 (same second) since it uses >= semantics, causing the job
to be immediately re-triggered hundreds of times.
Fix: Ask croner for the next occurrence starting from the NEXT second
(e.g., 13:00:01.000). This ensures we always skip the current/elapsed
second and correctly return the next day's occurrence.
This also correctly handles the before-match case: if nowMs is
11:59:59.500, we ask from 12:00:00.000, and croner returns today's
12:00:00.000 match.
Added regression tests for the spin loop scenario.
The `computeNextRunAtMs` function used `nowSecondMs - 1` as the
reference time for croner's `nextRun()`, which caused it to return the
current second as a valid next-run time. When a job fired at e.g.
11:00:00.500, computing the next run still yielded 11:00:00.000 (same
second, already elapsed), causing the scheduler to immediately re-fire
the job in a tight loop (15-21x observed in the wild).
Fix: use `nowSecondMs` directly (no `-1` lookback) and change the
return guard from `>=` to `>` so next-run is always strictly after
the current second.

* fix(cron): recover flat params when LLM omits job wrapper (#11310)
Non-frontier models (e.g. Grok) flatten job properties to the top level
alongside `action` instead of nesting them inside the `job` parameter.
The opaque schema (`Type.Object({}, { additionalProperties: true })`)
gives these models no structural hint, so they put name, schedule,
payload, etc. as siblings of action.
Add a flat-params recovery step in the cron add handler: when
`params.job` is missing or an empty object, scan for recognised job
property names on params and construct a synthetic job object before
passing to `normalizeCronJobCreate`. Recovery requires at least one
meaningful signal field (schedule, payload, message, or text) to avoid
false positives.
Added tests:
- Flat params with no job wrapper → recovered
- Empty job object + flat params → recovered
- Message shorthand at top level → inferred as agentTurn
- No meaningful fields → still throws 'job required'
- Non-empty job takes precedence over flat params
* fix(cron): floor nowMs to second boundary before croner lookback
Cron expressions operate at second granularity. When nowMs falls
mid-second (e.g. 12:00:00.500) and the pattern targets that exact
second (like '0 0 12 * * *'), a 1ms lookback still lands inside the
matching second. Croner interprets this as 'already past' and skips
to the next occurrence (e.g. the following day).
Fix: floor nowMs to the start of the current second before applying
the 1ms lookback. This ensures the reference always falls in the
*previous* second, so croner correctly identifies the current match.
Also compare the result against the floored nowSecondMs (not raw nowMs)
so that a match at the start of the current second is not rejected by
the >= guard when nowMs has sub-second offset.
Adds regression tests for 6-field cron patterns with specific seconds.
* fix: add changelog entries for cron fixes (#12124) (thanks @tyler6204)
* test: stabilize warning filter emit assertion (#12124) (thanks @tyler6204)
When anchorMs is not provided (always in production), the schedule
computed nextRunAtMs as nowMs, causing jobs to fire immediately and
repeatedly instead of at the configured interval.
- Change nowMs <= anchor to nowMs < anchor to prevent early return
- Add Math.max(1, ...) to ensure steps is always at least 1
- Add test for anchorMs not provided case
