# Stage 96: Verify Searchability (aq96_verify_surface_searchability / DB-UNIT-02)

Probes whether a surface's native search can see inside nested archives, AST symbols, and IO graphs, spawning non-blocking indexing regimes when insufficient.

- Atomic micro-queue: `aq96_verify_surface_searchability` (visibility: `public_commons`)
- Backing database unit: `DB-UNIT-02` (`Source Acquisition & Findability Taxonomy Core`)
- Database cell: `entities-db.teleon.dev` (`teleon_core.acquisition_seed_registry`, `teleon_core.skos_findability_concepts`, `teleon_core.capability_gap_ledger`)
- Claim row hydration: `single_self_contained_flat_task_row` (100% context inline, normalized writeback)
- Track 2 Sister queue (`SISTER-02`): `sq02-improve-findability-queue.teleon.dev` (Improve source yield, diversify domain priorities, and add new languages, synonyms, and harvesting routines.)
- Lanes: Recall & Latency Probe, Nested ZIP Visibility, Async Regime Spawn

## Execution engines & AI Agent freedom contract

- **Deterministic (0 model calls)**: `skos_lexical_normalizer_v1` (Known-item recall, archive-visibility & latency tester)
- **Hybrid (<=1 model call)**: `bilingual_card_tagger_v1`
- **AI Agent & Bot Fleet (1..6 calls)**: `deep_gap_hunter_and_harvester_v1` (Search regime gap diagnostician)
  - Contract: **Instructions + Resources + Freedom to search for new resources and new ways not bound by instructions**

## Database invariants

- Discovery stays effect-free; external repository fetches require pinned source connector grants.
- Record every inspected candidate, rejection reason, and license pin.

## External & internal bot fleet actions

- Confirm native search blind spots on 30TB Google Drive folders with nested multi-GB ZIPs
- Spawn HTTP 206 central-directory inspection and CodeGraph indexing without blocking solves
- Measure baseline precision, recall, and latency per surface

## Sister self-tuning areas

- Reprioritize starved creative/scientific domains via urgency weights
- Add new languages (fr, ko, ar, hi) and domain-specific colloquial synonyms
- Demote repetitive repository metadata extraction into deterministic code_blocks
