When a cron job fires and completes within the same wall-clock second it
was scheduled for, the next-run computation could return undefined or the
same second, causing the scheduler to re-trigger the job hundreds of
times in a tight loop.
Two-layer fix:
1. computeJobNextRunAtMs: When computeNextRunAtMs returns undefined for a
cron-kind schedule (edge case where floored nowSecondMs matches the
schedule), retry with the ceiling (next second) as reference time.
This ensures we always get the next valid occurrence.
2. applyJobResult: Add MIN_REFIRE_GAP_MS (2s) safety net for cron-kind
jobs. After a successful run, nextRunAtMs is guaranteed to be at
least 2s in the future. This breaks any remaining spin-loop edge
cases without affecting normal daily/hourly schedules (where the
natural next run is hours/days away).
Fixes#17821
Previously, if one cron job had a malformed schedule expression (e.g. invalid cron syntax),
the error would propagate up and break the entire scheduler loop. This meant one misconfigured
job could prevent ALL cron jobs from running.
Changes:
- Wrap per-job schedule computation in try/catch in recomputeNextRuns()
- Track consecutive schedule errors via new scheduleErrorCount field
- Log warnings for schedule errors with job ID and name
- Auto-disable jobs after 3 consecutive schedule errors (with error-level log)
- Clear error count when schedule computation succeeds
- Continue processing other jobs even when one fails
This ensures the scheduler is resilient to individual job misconfigurations while still
providing visibility into problems through logging.

- Enhanced cron-tool logic to handle new run modes and ensure compatibility with existing job structures.
- Added new tests for delivery plan consistency and job execution behavior under various conditions.
- Improved normalization functions to handle wake mode and session target casing.
This refactor aims to streamline cron job configurations and enhance the overall user experience with clearer defaults and improved functionality.
* test: enhance cron job functionality and UI
- Added tests to ensure the isolated agent correctly announces the final payload text when delivering messages via Telegram.
- Implemented a new function to pick the last deliverable payload from a list of delivery payloads.
- Enhanced the cron service to maintain legacy "every" jobs while minute cron jobs recompute schedules.
- Updated the cron store migration tests to verify the addition of anchorMs to legacy every schedules.
- Improved the UI for displaying cron job details, including job state and delivery information, with new styles and layout adjustments.
These changes aim to improve the reliability and user experience of the cron job system.
* test: enhance sessions thinking level handling
- Added tests to verify that the correct thinking levels are applied during session spawning.
- Updated the sessions-spawn-tool to include a new parameter for overriding thinking levels.
- Enhanced the UI to support additional thinking levels, including "xhigh" and "full", and improved the handling of current options in dropdowns.
These changes aim to improve the flexibility and accuracy of thinking level configurations in session management.
* feat: enhance session management and cron job functionality
- Introduced passthrough arguments in the test-parallel script to allow for flexible command-line options.
- Updated session handling to hide cron run alias session keys from the sessions list, improving clarity.
- Enhanced the cron service to accurately record job start times and durations, ensuring better tracking of job execution.
- Added tests to verify the correct behavior of the cron service under various conditions, including zero-delay timers.
These changes aim to improve the usability and reliability of session and cron job management.
* feat: implement job running state checks in cron service
- Added functionality to prevent manual job runs if a job is already in progress, enhancing job management.
- Updated the `isJobDue` function to include checks for running jobs, ensuring accurate scheduling.
- Enhanced the `run` function to return a specific reason when a job is already running.
- Introduced a new test case to verify the behavior of forced manual runs during active job execution.
These changes aim to improve the reliability and clarity of cron job execution and management.
* feat: add session ID and key to CronRunLogEntry model
- Introduced `sessionid` and `sessionkey` properties to the `CronRunLogEntry` struct for enhanced tracking of session-related information.
- Updated the initializer and Codable conformance to accommodate the new properties, ensuring proper serialization and deserialization.
These changes aim to improve the granularity of logging and session management within the cron job system.
* fix: improve session display name resolution
- Updated the `resolveSessionDisplayName` function to ensure that both label and displayName are trimmed and default to an empty string if not present.
- Enhanced the logic to prevent returning the key if it matches the label or displayName, improving clarity in session naming.
These changes aim to enhance the accuracy and usability of session display names in the UI.
* perf: skip cron store persist when idle timer tick produces no changes
recomputeNextRuns now returns a boolean indicating whether any job
state was mutated. The idle path in onTimer only persists when the
return value is true, eliminating unnecessary file writes every 60s
for far-future or idle schedules.
* fix: prep for merge - explicit delivery mode migration, docs + changelog (#10776) (thanks @tyler6204)
* fix(cron): handle legacy atMs field in schedule when computing next run
The cron scheduler only checked for `schedule.at` (string) but legacy jobs
may have `schedule.atMs` (number) from before the schema migration.
This caused nextRunAtMs to stay null because:
1. Store migration runs on load but may not persist immediately
2. Race conditions or file mtime issues can skip migration
3. computeJobNextRunAtMs/computeNextRunAtMs only checked `at`, not `atMs`
Fix: Make both functions defensive by checking `atMs` first (number),
then `atMs` (string, for edge cases), then falling back to `at` (string).
This ensures jobs fire correctly even if:
- Migration hasn't run yet
- Old data was written by a previous version
- The store was manually edited
Fixes#9930
* fix: validate numeric atMs to prevent NaN/Infinity propagation
Addresses review feedback - numeric atMs values are now validated with
Number.isFinite() && atMs > 0 before use. This prevents corrupted or
manually edited stores from causing hot timer loops via setTimeout(..., NaN).
