R12 S3 Closure-Complete Local Action Result
Decision: reject_closed_s3_v1_2_for_confirmation
Exact finite action closure is mechanically correct but does not rescue the end-to-end long program. The remaining dominant error is the frozen compiler's direction prediction under long source surfaces, not state recurrence, amount, or the S3 action algebra.

Depth-eight mean is 83.824% answers / 79.706% state / 51.471% complete chains. Gold identity is 83.529% / 80.294% / 55.000%. Short and lexical gates pass; the frozen mean attribution/state/chain, ordered, gold, and direction gates fail.
Relative to learned equivariant v1.1, closed action raises long mean answers 84.180% -> 85.303%, exact state 80.713% -> 82.031%, and complete chains 60.059% -> 63.281%. Gold improves by 1.270 / 1.416 / 3.613 points. These modest gains show that continuous transition selection contributed error but was not the principal long-context failure.
Mechanistic diagnosis
The action table itself is exhaustive and exact. The frozen amount classifier is 100% accurate on every evaluated arm. Direction is also 100% on the short compositional board, but falls to 93.403% on the known-atom depth board and 70.776% on lexical OOD. Because one wrong direction changes the exact state, later entity-location measurements and complete-chain accuracy compound that upstream compiler error even under gold identity.
A corpus audit finds that all 12 direction token sequences on the depth board are exact training atoms: six left and six right forms, with zero cross-class collisions. The contextual kind head is therefore discarding a relation that the source-pointer channel can in principle retain. The next bounded arm may decode the frozen operation-kind pointer through a lexicon built only from training spans, fall back to the neural kind head for unmatched sequences, and feed that categorical direction into the same exact action table. No development labels, executor fit, or confirmation may enter that lexicon.
V1.2 does not authorize confirmation, autonomous planning, learned halt, free-form language reasoning, or novelty.
