R12 ER-CST Neural Adapter Preregistration Amendment v1.2
Protocol: R12-ER-CST-v1.2-neural-adapter
Status: locally admitted before source freeze, board seed, training seed, H100 job, output, or scored access.
Closed v1.1 defect
V1.1 restored the categorical query interface but retained eight event slots. Because the tied executor tests HALT before applying a card, eight slots can encode at most seven active updates followed by HALT. The frozen task requires balanced depths one through eight. V1.1 is therefore closed before any board seed or data bytes existed.
Sole v1.2 change
V1.2 increases event slots from eight to nine and physical records from twelve to thirteen. This permits eight active card applications followed by one explicit persistent HALT. No recurrent rule, supervision type, optimizer, control, evaluator, or threshold changes.
The thirteen-record role head and embeddings add exactly 769 parameters:
| Quantity | V1.2 |
|---|---|
| immutable Shohin trunk | 125,081,664 |
| compiler | 67,336,999 |
| tied categorical motor | 2,438 |
| categorical reader | 835 |
| complete deployed system | 192,421,936 |
| trainable parameters | 11,716,385 |
| headroom below 200M | 7,578,064 |
The compiler whitelist remains 98 tensors and the motor remains four tensors,
but the changed role tensor shapes produce trainability contract SHA-256

The exact confirmed-parent state and excluded-state digests remain

and 1ad33273f7db5073b4cfac0e79031544a74b74914050026642110aee484c94e7.
The board builder must enforce exactly one HALT, depths one through eight, thirteen nonempty physical program lines, and exact executor agreement before any scored split is sealed. A board seed may be drawn only after the v1.2 architecture and fresh-board source are committed and pushed.
