R12 SD-CST Complete Physical-Record Front-End v1.1 Preregistration

Status: closed and rejected under the frozen gates. Sole job 694203 completed cleanly on H100 evc22; full result: R12_SD_CST_COMPLETE_PHYSICAL_RECORD_BUS_V1_1_RESULT.md.

Exact scientific source b93b17b3ee5c096509cd1ab0d903ef7a9287d3a3 preceded raw beacon 14330060956843215829 and signed-safe seed 5106688919988440021. The dedicated key raises minimum binding pointer to 61.0% and packet to 47.45%, but minimum initial-occurrence pointer remains 0%. Decision: reject_declaration_key_repair.

Claim class: consumed-training declaration-address repair only. This cannot establish fresh-language generalization, native reasoning, or Shohin promotion.

1. Frozen diagnosis

Complete local-front-end v1 reaches 100% minimum held-out query, query pointer, line pointer, event pointer, kind, and amount, but only 5.15% binding pointer, 0% initial-occurrence pointer, 15.0% initial state, and 13.45% complete packet. Fit is nearly identical. Its declaration queries and projection move and retain large gradients, while their address losses remain near uniform.

V1 addresses six declaration occurrences through record_entity_key, a frozen projection learned for event-line entity extraction. V1.1 tests the smallest representation repair: a declaration-specific trainable key projection.

2. Fixed parent and ownership

V1.1 reconstructs the exact joint parent and retained independent physical bus, then loads only the successful eight-tensor local_query_* endpoint from v1 checkpoint SHA-256 30b75305031b1e2f67a24f98b4907d2d65bc847310ea406d25f34c7b9611e1b4. The failed declaration query table and query projection are reset from the new post-source-commit seed. One new bias-free 384 by 384 declaration-key projection is initialized from the same seed.

Only these three tensors train:

1. local_declaration_queries;
2. local_declaration_query_projection.weight; and
3. local_declaration_key_projection.weight.

The successful query path, 88-tensor physical record bus, joint parent, fingerprint matcher, tape, executor, motor, reader, and Shohin trunk remain frozen under one excluded-state digest.

3. Exact parameter contract

No parameter may be added after the scientific source commit. Historical 150M contracts remain unchanged.

4. Fixed data, optimization, and gates

The pilot reads only consumed train SHA-256 b7756dbf8d4401dbc5fb897dee53f68758e27200b1ce0d2387631f2f0205ec25 with the same fixed 12,000-semantic fit and disjoint 2,000-semantic heldout partition, four renderer views each, two epochs / 3,000 updates, family batch eight, AdamW lr 2e-4, betas (0.9, 0.95), weight decay 0.01, 100-update warmup, cosine decay, clipping 1.0, and renderer-consistency weight 1.0. Development, confirmation, answers, states, trajectories, and executor feedback remain unreachable.

The frozen v1 absolute gates are unchanged: minimum fit packet 99%; heldout packet and initial state 95%; query, query pointer, binding pointer, initial-occurrence pointer, event pointer, kind, identity, and amount 99%; excluded state byte-identical; system strictly below 200M; scored access 0/0.

All gates passing yields retain_declaration_key_repair_for_fresh_board. Any failure yields reject_declaration_key_repair. A pass credits the three-tensor repair package only; it remains conventional compiler mechanics and merely authorizes a separately committed fresh-board contract.
