- JobScheduler: a stored job whose zone lookup throws no longer fails StartAsync; timer re-armed under the lock;
a delivery cut off by shutdown isn't recorded (one-offs fire again after restart); CancelJobAsync in one step
- Schedules.ParseAt: ISO 8601 with a date only (no machine-clock date for a bare 09:00)
- core: a FollowUp prompt that loses the race to a starting run joins it as a follow-up, not steering
- Telegram: TimeZoneFor tolerates non-numeric targets; RunPromptAsync waits only when queued; one agent dir
- ScriptRunner: bad workspace paths are Failed, not exceptions; zone id helpers share TimeZoneIds.ToIana's rule
- tests: no wall-clock sleeps in scheduler tests; transcript-entry, disabled-scheduler and failing-prompt coverage
- docs: spec notes for the above; README row for the scheduler
Spec: a skipped one-off fires after the next start; the late note's placement and no-exit-code failure wording are pinned down; IsDeliverable is part of the watcher invariant and must not create a session; saves snapshot inside a serialising gate.
Spec: on Windows the command goes through Arguments like the bash tool, since cmd.exe doesn't parse ArgumentList quoting; the workspace is created if missing, and a timeout vs cancellation outcome is spelled out.
Adds AgentSessionOptions.TimeZone, AgenticCoreOptions.DefaultTimeZone, AgentSession.TimeZone, IExtensionHost.TimeZone, IExtensionContext.TimeZone (default member returning TimeZoneInfo.Local) and TimeZoneIds.ToIana, ahead of the rest of scheduler spec section 8. Spec sentences added to process-environment-hook section 4 and scheduler section 8.
