Suggest SCD2 Context Pack

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

• Cell host: lsh-db.teleon.dev
• Backlog table: teleon_core.search_retrieval_todo_backlog
• Hydration: Normalized supporting tables join server-side into 1 flat row on claim
• teleon_core.teleon_lsh_signatures_256
• teleon_core.bm25f_seven_field_postings
• teleon_core.roaring_trigram_inverted_index
• teleon_core.markov_l0_prefetch_transitions

• Retrieval stays deterministic at 0 model calls when optimize_mode=zero_model_deterministic.
• Return compact contract cards first; defer source bytes until inspect_or_stream.

Atomic micro-queue & Track 2 Sister objective

• Atomic queue: aq45_suggest_context_pack 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.

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

• Close superseded pack versions cleanly with valid_to_utc and append immutable pack_sk rows with edit_reason
• Stamp optional pack_* scalar columns ahead of time or hydrate on claim without blocking bare_baseline execution
• Sweep pack_sk variants in Store S8 grids to measure real lift against the no-extra-material baseline

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
