R12 S3 Training-Lexicon Action Development Result
Decision: qualify_lexical_closed_s3_v1_3_for_fresh_confirmation
The training-only lexical relation decoder closes the known-atom direction interface. Combined with ordered referential identity and exact S3 action, the source-deleted system executes three-to-eight-step programs at near-exact accuracy without training on composed or long programs.

Ordered depth-eight is 98.529% answers / 100% state / 98.824% complete chains. Mean depth-eight is 96.176% / 96.176% / 90.882%. Every frozen public gate passes.
Causal interpretation
The v1.2-to-v1.3 intervention changes no weight, state register, identity arm, amount head, query head, board, or executor. Restoring known direction atoms raises mean depth answers 85.303% -> 94.434%, state 82.031% -> 94.336%, and complete chains 63.281% -> 89.453%. Gold state/chains rise 86.328% / 70.508% to exactly 100% / 100%. This is the predicted signature of an upstream direction-transport failure.
The lexical-OOD control is equally important. None of its unseen direction phrases crosses the 0.5 training-pattern mass threshold, so coverage is 0% and scores remain byte-for-byte at the closed-action fallback baseline. The gain is not caused by matching known distractors or reading development labels.
The strongest complete arm is ordered identity plus lexical direction plus model-predicted amount and query plus exact S3 state/action. It receives source text only through frozen compiler pointers, deletes source states, and carries one categorical register through repeated calls. It was trained only on independent atomic updates; no composed or depth supervision fits any weight.
Boundary
This public development pass authorizes one independently seeded confirmation. It does not yet confirm the score. It handles known direction atoms, three referential identities, two bounded amounts, and externally supplied operation count/halt. It does not establish unseen direction semantics, autonomous plan induction, learned stopping, free-form language reasoning, or novelty.
