# Stage 138: Bitemporal Entity & Shard Sync (aq138_ingest_bitemporal_entity_and_market_shards / DB-UNIT-02)

Ingests public filing, registry, scholarly, and hiring deltas into bitemporal (valid_time, tx_time) shards and flags multi-domain strategic coincidences.

- Atomic micro-queue: `aq138_ingest_bitemporal_entity_and_market_shards` (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: SEC EDGAR / GLEIF / OpenAlex, Valid-Time vs Tx-Time, 4-Domain Coincidence

## Execution engines & AI Agent freedom contract

- **Deterministic (0 model calls)**: `skos_lexical_normalizer_v1` (Bitemporal interval normalizer, LEI/CIK linker & coincidence scorer (0 calls))
- **Hybrid (<=1 model call)**: `bilingual_card_tagger_v1`
- **AI Agent & Bot Fleet (1..6 calls)**: `deep_gap_hunter_and_harvester_v1` (Cross-signal strategic synthesis & anomaly verifier)
  - 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

- Preserve point-in-time historical truth alongside transaction arrival timestamps without overwrites
- Link corporate filings, LEI hierarchies, papers, and job postings to canonical Store S4 entities
- Trigger research tasks when 3+ independent signal domains shift simultaneously on one entity

## 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
