Stage 122aq122_apply_thp_v2_bidirectional_lensDB-UNIT-0448-Cell Hybrid Search, LSH & Retrieval Core

THP v2.0 Schema Lenses

Atomic flat-row micro-queue with 0-call slot and 5-role pod.

Transforms records losslessly between older v1 and newer v2 surface contracts via bidirectional Cambria lenses while preserving unknown future fields in _thp_passthrough_tail.

Execution Modes & Agent Freedom

Deterministic (0 calls): bm25f_roaring_lsh_zero_model_v1 (Bidirectional rename/default/scale lens interpreter (0 model calls))
Hybrid (<=1 call): query_intent_expansion_hybrid_v1
AI Agent (1..6): multi_hop_federated_scout_v1 (Legacy-to-modern API contract migration author; Instructions + Resources + Freedom to search for new resources and new ways not bound by instructions)

Outputs (Table Merge)

Transformed record with 0 dropped fields
Round-trip lossless proof

Modular 6-layer envelope & 0..32 Kleisli onion middlelayers (DB substrates exempt)

Inbound and outbound calls traverse versioned envelope layers and composable Kleisli middlelayers before reaching the swappable engine slot, while backing database kernels enforce 0 inline agent wrapper steps.

5-role component managing pod & engine-slot twins

0-Call Slot (R1_DET_ENGINE): Executes SQL, BM25F/Roaring, AST, or fuel-metered Wasm adapters behind a fixed typed engine_slot/v1, pairing pinned upstream OSS adapters with clean Teleon-native twins.
Solver+OpenSearch (R2_PRIMARY_SOLVER): Runs under Instructions + Resources + Freedom to search for new resources and new ways not bound by instructions on 1 self-contained depth-1 flat task row per lease.
Split-Supervisor (R3_QUEUE_SUPERVISOR): Watches queue depth, stalls, and context horizons; explodes oversized tasks into wave-ordered flat subtask rows while preserving the original parent intact for rollup verification and long-horizon benchmarking.
Repair+Shim (R4_DIAGNOSTIC_REPAIR): Reviews whether the edge contract itself failed before mutating code (LE-CONTRACT-002), repairs lease timeouts and schema mismatches, and synthesizes 0..32-step middlelayer shims.
CPOP+Distill (R5_VERIFIER_DISTILLER): Grades outputs across an independent model family (reviewer != producer) and distills recurring high-cost agent wins into 0-call deterministic Sister code.

Parent-preserving supervision, catch-all & optional SCD2 packs

Supervisor split (aq41): Oversized or stalled tasks split into wave-ordered subtask rows while keeping subdivided_parent intact for rollup verification and direct long-horizon benchmarks.
Optional SCD Type 2 packs (Store S12): Versioned pack_sk rows (valid_from_utc, valid_to_utc, is_current, edited_by) supply optional locales, settings, instructions, suggestion paths, and tools across bare_baseline, pre_materialized_flat, and on_demand_claim_hydrated modes.
Flexible carriers: inline_object, swhid_cas_pointer, http_206_byte_slice, d1_row_cursor, signed_r2_uri

Normalized tables, invariants & 1 flat task row

Retrieval stays deterministic at 0 model calls when optimize_mode=zero_model_deterministic.

Atomic micro-queue & Track 2 Sister objective

Atomic queue: aq122_apply_thp_v2_bidirectional_lens via q14-retrieval-probe-queue.teleon.dev
Track 2 Sister (SISTER-04): sq04-improve-search-queue.teleon.dev
Sister objective: Tune BM25F field weights, MMR diversity, synonym rings, multilingual stemmers, and 0..N retrieval steps.

host:lenses_teleon_devstore:S28lossless_roundtrip:true

Bot & harness fleet actions (Codex, Claude Code, ChatGPT, Dots, Meta Muse, GrokBot)

Downcast v2 records for v1 agents while stashing v2/v3 fields safely in _thp_passthrough_tail
Upcast v1 responses back to v2 losslessly with exact affine unit rescaling
Decouple independent frontend surface release cadences from shared substrate upgrades

Sister self-tuning areas & HTTP queue submission

Tune 7-field BM25F weights and MMR diversity_floor on frozen retrieval benchmarks
Expand multilingual query synonym tables and domain aspect boosters
Add pre-retrieval / post-retrieval deterministic reranking steps and code_blocks
