- Add a database-backed supervisor with durable scheduling, fenced leases,
cooldowns, bounded worker concurrency and expired-lease restart recovery.
- Default new goals to persistent execution with zero meaning unlimited
cumulative budget; preserve legacy goals and explicit positive limits.
- Yield bounded graph segments to the supervisor instead of ending unfinished
goals at graph-local continuation limits. Require persisted checklist
evidence before accepting completion, including concurrent criterion edits.
- Share conversation admission across interactive and background execution;
preserve partial replies, usage and queued user input during interruption.
- Persist Stop and missing-input pauses, respect approval boundaries, and
commit resume and approval-denial transitions with correct transactions.
- Retry identifiable transient failures with backoff; retain visible pauses
for budget limits and errors that require review instead of replaying tools.
- Expose owner-authorized execution status and reconnectable scheduling events;
add H2, MySQL and Kingbase migrations, API types and bilingual documentation.
Validation: 298 focused backend tests passed, including persistence, restart
scheduling, approval races, cancellation, admission and existing runtime tests.
Frontend type checking, bundled-doc parity and ID precision checks passed.
V188 is registered and all three dialects have unique migration versions;
the migration-map audit still reports 95 pre-existing missing registrations.
Scope: single-backend native runtime. Recovery checks existing state before
repeating effects; this does not promise exactly-once external tool execution.
Normalize stream idle timeout overrides, make WebChat orphan cleanup use exact run handles so stale callbacks cannot mutate replacement runs, and preserve approval replay usage metadata with regression coverage.
Use detach rather than complete for WebChat SSE disconnect callbacks, add an orphan-run grace policy for subscriberless active runs, and emergency-save partial assistant output when reclaimed.
