R12 ER-CST Witness Equality Bus v1.1 Development Result

Development decision: authorize_one_sealed_confirmation

Final status: independently confirmed; see R12_ER_CST_WITNESS_EQUALITY_CONFIRMATION_RESULT.md.

Frozen identity

Result

Treatment joint accuracy by depth is 100% at depths one through six, 99.219% at depth seven, and 96.875% at depth eight. Its four renderer joint rates are 99.414%, 99.414%, 99.609%, and 99.609%. All 14 frozen scientific gates pass. The independent assessor recomputes all metrics from raw hard predictions and passes all eight artifact, parameter, source, metric, gate, and custody checks.

Interpretation

ER-CST v1 failed despite perfect structural parsing because a generic record residual could not infer a fresh operation's S_3 permutation from six opaque before/after name occurrences. V1.1 repairs exactly that interface:

1. six dedicated model-owned occurrence queries locate the three before and three after names for each rule;
2. learned byte-bigram fingerprints represent those occurrences;
3. a learned 3x3 equality matrix compares after names with before names;
4. finite assignment scores select one of the six legal permutations; and
5. the resulting cards are composed only by the pre-existing source-deleted recurrent categorical motor.

The two matched controls make the causal conclusion unusually sharp. Destroying cross-occurrence equality or deranging card semantics collapses complete packet and joint accuracy to approximately zero while leaving event order, HALT, and query interfaces intact. The improvement is therefore not attributable to more executor capacity, renderer memorization, direct answer supervision, or a host parser. It is a learned episodic equality-and-assignment compiler feeding a model-owned recurrent machine.

Artifacts

All artifacts are mirrored read-only on the Mac with matching hashes. A local independent-assessor replay is byte-identical to the Newton assessment.

Claim boundary

This development result establishes bounded fresh episodic S_3 rule inference, source-deleted categorical composition, internal halt, and late-query readout on one split. It is not yet confirmed and does not establish unrestricted language grounding, arbitrary operation induction, arithmetic, planning, or broad general reasoning. The only authorized next score is the preregistered one-read sealed confirmation in R12_ER_CST_WITNESS_EQUALITY_CONFIRMATION_PREREG.md.
