HOT Lease & Zombie Reaper

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

Decouples high-frequency lease/heartbeat mutations into narrow teleon_active_leases rows with monotonic fencing tokens and deterministic zombie reaping.

Execution Modes & Agent Freedom

Deterministic (0 calls): cas_fastcdc_swhid_ingestor_v1 (Narrow HOT-lease fencer (409 on stale token) & expired-lease reaper (0 calls))
Hybrid (<=1 call): cas_license_boundary_disambiguator_v1
AI Agent (1..6): cas_unstructured_bundle_extractor_v1 (Stuck-task recovery & lane liquidity balancer; Instructions + Resources + Freedom to search for new resources and new ways not bound by instructions)

Outputs (Table Merge)

Fenced HOT lease row (cold S21 untouched)
Reaped zombie task slate

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

Atomic micro-queue & Track 2 Sister objective

Atomic queue: aq135_hot_lease_and_zombie_reaper via q03-seed-queue.teleon.dev
Track 2 Sister (SISTER-01): sq01-improve-cas-queue.teleon.dev
Sister objective: Tune chunk boundaries, add AST language grammars, and shrink byte-slice token overhead.

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

Mutate narrow lease and heartbeat state in teleon_active_leases without rewriting cold S21 payloads
Reject delayed split-brain workers deterministically with 409 stale_fencing_token_refused
Reap expired leases and bump fencing_token atomically across the 12 physical execution lanes

Sister self-tuning areas & HTTP queue submission

Tune FastCDC chunk target size per language grammar
Add AST symbol-slicing code_blocks for new file formats (WGSL, USD, Typst)
Expand provenance and license synonym mappings
