R12 Complete-Compiler Parameter-Islands Preregistration
Protocol: r12_referential_literal_pointer_compiler_v1_3_islands_development
Status: frozen before v1.3 fitting or scoring
Selection boundary: exposed-development mechanism diagnostic only
Hypothesis
The v1.2 structural parser learned substantially better ordered bindings, but its operation-kind head stayed at chance because token-role supervision bypassed the free semantic slot. The zero-fit hybrid of v1.2 structure and v1.1 operation classes recovered 48.193% answers and 33.740% semantic programs. Therefore:
A physically separate semantic reader over the original frozen causal states can preserve operation meaning while a bidirectional structural reader learns source roles.
Single treatment change from v1.2
Keep v1.2 unchanged. Add a separate two-layer semantic slot decoder with its own layer norm and 576-to-256 memory projection over frozen layer-19 states. Only the operation-kind classifier reads this island. The structural encoder, role head, ten pointers, role loss, data, optimizer, and host executor remain unchanged.
No island receives line spans, structured values, operation labels, renderer IDs, or answers at inference. The only inference inputs remain source token IDs and the source-length mask.

Passing all gates authorizes a new untouched factorized-language board and favorable controls only. It does not authorize v1.1 confirmation, an executor connection, a native-reasoning claim, or a novelty claim.
