R12 ER-CST Fresh Board Preregistration Amendment v1.2

Status: pre-training identifiability repair. No training seed, H100 job, neural output, development access, or confirmation access exists.

The v1.1 board from exact source fba34cdc9bfab75882dee8093b07ab96042d4a07 and seed 1686667709479653771 passed every integrity gate and remains unopened, but a post-admission architecture/data audit found that its three rule-card records had arbitrary latent slot IDs with no source-visible address. Exact ordered card scoring would therefore reward accidental compact-name correlations or an unidentifiable permutation choice.

That board is closed before training. V1.2 adds only a one-character rule-slot address to each determining witness record: W1/W2/W3 or the matched renderer's L1/L2/L3. The address identifies where to store a learned card; it reveals no permutation, opcode binding, execution result, query, state, or answer. Physical line storage remains independently shuffled, so the compiler must still parse the address, infer operation meaning from before/after symbol equality, and bind later opaque opcode uses.

The independent production parser now requires exactly one of every rule slot and checks each slot against the target. Row counts, family construction, name bijection, renderer cosets, model architecture, parameter count, supervision, controls, gates, and custody remain unchanged. The old board seed may not be reused. Commit and push this exact repair before drawing a new board seed.
