This post-hoc audit reads only the same 2,000-semantic consumed-training heldout partition already evaluated by v1.1. Development and confirmation remain unreachable. It reconstructs exact endpoint SHA-256 46697b3942fdfd2edfec06cea6cb119ad507adcdee4a99330fd06bc79e5b3e88 and does not optimize or modify any tensor.

For each of four heldout renderers and each of the six declaration queries, it records top-one target-span exactness, probability mass on the target span, target NLL, and a seven-way confusion: the three binding occurrences, three initial-list occurrences, or other bytes. It also reproduces all-three binding and all-three initial exactness.

The audit decides only the next representation hypothesis:

• initial queries selecting binding occurrences supports separate binding/initial key banks;
• selecting the wrong initial occurrence supports stronger occurrence/position conditioning;
• selecting other bytes supports a declaration-local nonlinear token parser;
• diffuse low target mass everywhere rejects a readout-only repair and requires adapting declaration-local token memory.

No threshold is promoted, no failed run is rescored, and no reasoning or fresh generalization claim can follow from this audit.

Observed result: all 48,000 top-one decisions select one of the six true entity spans and none select other bytes, but the middle initial occurrence is only 0--10.35% exact. This admits an occurrence-role classifier, not more v1.1 epochs or a broader encoder.
