R12 S3 Lexical Closed-Action Confirmation Result
Decision: reject_lexical_closed_s3_confirmation
The fresh board strongly reproduces the public score and passes both causal controls, but it misses the preregistered perfect gold execution gate by two direction decisions out of 11,248. The result is a near-confirmation, not a confirmed claim.

Ordered scores clear the overall and every-depth gates. Mean clears 90% / 90% / 82%. Operation replacement changes all 2,048 rows and drops answers by 64.111 points and state by 81.396 points. Query replacement changes all rows, drops answers by 98.682 points, and leaves state exactly unchanged. Receipts and hashes pass.
The sole failed gate is gold exact execution. Lexicon coverage is 99.813%; the neural fallback repairs most unmatched references, but two direction decisions remain wrong. Gold therefore has one incorrect final state and two rows with a non-exact full chain. The frozen gate required exactly 100% state and chains.
Consequence
Do not relax the 0.5 threshold or rerun this board. Seal it. Return to public development with a structural decoder that asks whether the compiler pointer's global maximum lies inside a known exact token pattern. That rule has no tuned mass threshold: known pointed atoms use their class, while an unseen pointed phrase falls back to the neural kind head. It must pass public lexical-OOD fallback and exact-depth gates before a wholly new independent confirmation.
This result supports a strong known-atom source-deleted execution component but does not confirm it under the locked contract. It does not establish unseen- phrase semantics, autonomous planning, learned halt, free-form language reasoning, or novelty.
