# Stage 123: Early Crystallizer (aq123_predict_early_catchall_crystallization / DB-UNIT-11)

Predicts high-leverage recurring workloads at N=16 items from velocity, DAG centrality, LLM cost, and tenant spread, while coalescing cold queues back into archetypes.

- Atomic micro-queue: `aq123_predict_early_catchall_crystallization` (visibility: `public_commons`)
- Backing database unit: `DB-UNIT-11` (`Pre-Effect Handshakes, SWHID Parameter Bundles & Kleisli Wrappers Core`)
- Database cell: `queues-db.teleon.dev` (`teleon_core.teleon_surface_handshakes`, `teleon_core.component_parametric_configs`, `teleon_core.schema_migration_casters`)
- Claim row hydration: `single_self_contained_flat_task_row` (100% context inline, normalized writeback)
- Track 2 Sister queue (`SISTER-11`): `sq11-improve-handshakes-queue.teleon.dev` (Synthesize cross-version up/down-casters, compress middleware overhead, and maintain 10-host plugin parity.)
- Lanes: C_pred >= 75 at N=16, Zero-Codebase Queue Spec, Entropy Gardener

## Execution engines & AI Agent freedom contract

- **Deterministic (0 model calls)**: `thp_v1_hmac_and_schema_caster_v1` (4-signal C_pred scorer & cold-queue entropy gardener (0 model calls))
- **Hybrid (<=1 model call)**: `schema_drift_compat_advisor_v1`
- **AI Agent & Bot Fleet (1..6 calls)**: `cross_version_downgrade_shim_synthesizer_v1` (Parameterized queue template & routing-rule synthesizer)
  - Contract: **Instructions + Resources + Freedom to search for new resources and new ways not bound by instructions**

## Database invariants

- Unsupported versions fail closed prior to side effects unless a verified pure-function SchemaMigrationGate caster exists.
- Track-1 workers read pinned active_config_swhid snapshots and never mutate parameters mid-flight.

## External & internal bot fleet actions

- Graduate surging catch-all patterns at N=16 instead of waiting for N=100 unindexed pileups
- Crystallize new queues as parameter profiles over existing engines with 0 new codebases
- Coalesce stale <0.2-claim/hr queues back into parent archetypes to prevent queue sprawl

## Sister self-tuning areas

- Synthesize pure-function downgrade/upgrade shims for rolling 12-month SDK versions (DIM-03)
- Tune edge KV handshake cache TTLs and pre-warmed parameter bundles (DIM-07)
- Expand universal plugin hooks across ZCode, Claude Code, T3 Code/Chat, Zed, and Cursor (DIM-03, DIM-06)
