R12 SD-CST Complete Physical-Record Front-End v1.2 Result

Decision: retain_occurrence_head_for_fresh_board

Claim boundary: consumed-training compiler mechanics only. Development and confirmation access remained zero. This result does not establish fresh language transfer, self-directed execution, or native reasoning.

The clean Newton capsule was detached at the exact execution receipt. Runtime preflight verified all parent/data hashes, bf16 H100 allocation, exact parameter ownership, and a strict complete-system count below 200M.

2. Exact system

Only six tensors train: LayerNorm over each declaration byte, a shared 384-to-1536 GELU projection, and a 1536-to-6 occurrence-role classifier. The old failed declaration queries remain present but unused and frozen. The exact v1 query endpoint, physical event bus, all parent compiler paths, matcher, tape, executor, motor, reader, and Shohin trunk remain frozen under digest 200cd1bf03888b1353a267dfc3250ca4420de785e06d3df4b393c6a92d3d8842.

3. Result

Both easier held-out renderers are exact on all fields. Each difficult declaration renderer has 1,984/2,000 strict all-three initial-pointer matches, but all 2,000 initial values and all 2,000 complete packets remain exact. Fit packet accuracy is at least 11,999/12,000 per renderer and reaches 12,000/12,000 on both difficult renderers. Epoch one already passes every absolute gate; epoch two preserves the result.

The causal interpretation is specific. The read-only audit showed that the v1.1 bilinear queries always found a true entity span but confused the six occurrence roles. Replacing only that readout with a nonlinear local six-class head resolves the ambiguity while every successful frozen interface remains exact. This establishes a complete finite compiler interface on the consumed renderer family. It does not show transfer to unseen source language.

4. Gate accounting

All twelve preregistered gates pass:

1. fit packet at least 99%;
2. held-out packet at least 95%;
3. held-out initial state at least 95%;
4. held-out query at least 99%;
5. held-out query pointer at least 99%;
6. held-out binding pointer at least 99%;
7. held-out initial-occurrence pointer at least 99%;
8. held-out event pointer at least 99%;
9. held-out kind, identity, and amount at least 99%;
10. excluded state byte-identical;
11. complete system strictly below 200M; and
12. scored access remains 0/0.

The exact decision is retain_occurrence_head_for_fresh_board. This authorizes one separately committed board with new names, renderer/source families, train/development/sealed-confirmation splits, matched controls, source deletion, and the unchanged categorical executor. It does not authorize reuse or opening of any closed development or confirmation split.
