# Stage 23: Event Feeds & Codemods (aq23_event_codemods / DB-UNIT-10)

Matches signed CVE, deprecation, and model-pricing advisories against stored SWHIDs and queues sandbox-verified AST migrations.

- Atomic micro-queue: `aq23_event_codemods` (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: Signed Advisories, SWHID Blast Match, AST Codemods

## Execution engines & AI Agent freedom contract

- **Deterministic (0 model calls)**: `signed_cloudevent_blast_matcher_v1` (Signed CloudEvents & SWHID dependency matcher)
- **Hybrid (<=1 model call)**: `deprecation_migration_summarizer_v1`
- **AI Agent & Bot Fleet (1..6 calls)**: `autonomous_codemod_patch_synthesizer_v1` (Automated AST codemod synthesizer)
  - 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

- Match upstream breaking API changes to exact affected code assets
- Synthesize and sandbox-test deterministic AST codemods once for all callers
- Deduplicate noisy upstream advisories into crisp actionable deltas

## 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)
