# Stage 41: Supervise & Split (Keep Parent) (aq41_supervise_split_keep_parent / DB-UNIT-10)

Monitors queue items for stalls or horizon risk and breaks oversized tasks into wave-ordered flat subtask rows while keeping the original parent intact.

- Atomic micro-queue: `aq41_supervise_split_keep_parent` (visibility: `public_commons`)
- Backing database unit: `DB-UNIT-10` (`Signed Agent Event Feeds, Advisories & Migration Streams Core`)
- Database cell: `entities-db.teleon.dev` (`teleon_core.agent_event_feeds`, `teleon_core.signed_deprecation_advisories`, `teleon_core.verified_codemod_migrations`)
- Claim row hydration: `single_self_contained_flat_task_row` (100% context inline, normalized writeback)
- Track 2 Sister queue (`SISTER-10`): `sq10-improve-feeds-queue.teleon.dev` (Filter advisory alert noise, tune urgency weights, and pre-verify deterministic codemod patches.)
- Lanes: Keep Original Intact, Wave Subtask Nodes, Rollup & Benchmark

## Execution engines & AI Agent freedom contract

- **Deterministic (0 model calls)**: `signed_cloudevent_blast_matcher_v1` (Stall/horizon detector, SWHID parent snapshotter & rollup verifier)
- **Hybrid (<=1 model call)**: `deprecation_migration_summarizer_v1`
- **AI Agent & Bot Fleet (1..6 calls)**: `autonomous_codemod_patch_synthesizer_v1` (Non-destructive task-boundary slicer & long-horizon benchmark referee)
  - Contract: **Instructions + Resources + Freedom to search for new resources and new ways not bound by instructions**

## Database invariants

- Breaking deprecation advisories join against pinned SWHID dependency edges before spawning repair tasks.
- Every migration codemod must pass deterministic sandbox verification before broadcast.

## External & internal bot fleet actions

- Snapshot the original task payload and SWHID before splitting so zero parent intent is ever lost
- Emit independent depth-1 subtask rows with parent_task_id and wave order while keeping long-horizon direct solving eligible
- Verify rolled-up subtask outputs against the original parent acceptance contract on completion

## Sister self-tuning areas

- Tune alert deduplication and breaking-change urgency weights (DIM-01, DIM-06)
- Synthesize deterministic AST codemod code_blocks for common API migrations (DIM-03)
- Tune edge delta sync intervals for high-priority security bulletins (DIM-07)
