# Stage 94: Progressive L0-L2 Cards (aq94_serve_progressive_l0_l1_l2_cards / DB-UNIT-02)

Serves progressive capability disclosure (cards.teleon.dev) from compact <=150-token L0 discovery cards to L1 typed IOPE contracts with AST/node byte offsets and L2 HTTP 206 byte-range source slices, saving >85% context tokens.

- Atomic micro-queue: `aq94_serve_progressive_l0_l1_l2_cards` (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: L0 <=150-Tok Card, L1 Typed IOPE + Offsets, L2 HTTP 206 Slice

## Execution engines & AI Agent freedom contract

- **Deterministic (0 model calls)**: `skos_lexical_normalizer_v1` (L0 token-budget card compiler, L1 node byte-offset indexer & HTTP 206 byte-slice responder)
- **Hybrid (<=1 model call)**: `bilingual_card_tagger_v1`
- **AI Agent & Bot Fleet (1..6 calls)**: `deep_gap_hunter_and_harvester_v1` (Progressive capability scout & surgical symbol/node slice consumer)
  - 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

- Discover 20+ candidate capabilities via <=150-token L0 cards before inspecting L1 typed port contracts
- Fetch exact L2 symbol or SVG/glTF node byte ranges via HTTP 206 instead of loading entire repositories into context
- Audit eager-vs-progressive token amortization alongside benign-twin false-positive rates on switchboard.teleon.dev

## 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
