# R12 S9.1 Alpha-Closed Structured Compiler Board

**Status:** frozen and unevaluated

**Neural source commit:** `863a210`

**Board seed:** `1370124171784245712`

**Training seed:** `8076551815802451212`

## Frozen experiment

S9.1 retains the frozen 300k Shohin trunk, closed S8.1 initializer, S9
occurrence-quotient encoder, S7 cyclic generator, and S8 graph/runtime. The two
changes frozen at the source commit are:

1. equal-budget original/operation-recoded training pairs with a 0.25 aligned
   role-logit orbit loss; and
2. syntax-only top-eight non-overlapping child assignment around model-selected
   card/event anchors.

Each treatment/control arm receives 24,000 unique sources, 48,000 charged views,
batch 64, and 750 optimizer updates. No train state, answer, recurrent trace, or
score-board relation is provided.

- no train final state or answer;
- zero exact-prompt, 13-gram, or split-name overlap;
- development/confirmation access `0/0`;
- original and recoded maximum 455/512 tokens; and
- 8,568 nonce recodes change token width.

## Authorized next action

Commit this receipt plus the report and generator cells. Sync exact source,
large board payloads, tokenizer, protected base, and closed initializer to
Newton and hash-verify them. Then run one serial treatment/no-class/shuffled
training and sole development assessment. The sealed confirmation file must
remain unread by model/evaluator code unless every development gate passes.
