R12 S3 Structural Pointer-Anchor Confirmation Preregistration

Status: completed once; every frozen gate passes and the board is sealed.

Infrastructure attempt seed 223317486517061319 is retired without a board or score. Newton lacked two already-tracked generator dependencies, so Python failed at import before output-directory creation. Syncing those unchanged repository files is the sole correction; candidate, generator, evaluator, board contract, arms, and gates do not change.

Confirmed Object

The candidate is commit 51ed8fc and public assessment a73b0915bebb91845415630072422c08747f70a94dc7cae98befd7b22ed52568: frozen ordinary source compiler, training-only 12-pattern lexicon, structural global pointer-anchor decoder with neural fallback, ordered relational identity, frozen amount/query heads, and closure-complete categorical S3 action/state. No weight may fit the confirmation board.

Fresh Board

After this protocol is committed, one unpredictable production seed may create 512 new semantic quartets / 2,048 rows balanced across depths 3--8. The existing generator excludes every factorized train/development and relational-public prompt, word 13-gram, entity name, and factor combination. Every direction is a training lexicon atom. CPU pop-insert and adjacent-swap executors must agree. Operation and query strata must admit semantic derangements within every depth.

All earlier confirmation boards and failures remain sealed and forbidden as inputs. A corpus-gate failure before model access retires that seed and records no score; no scored-board rerun is allowed.

Frozen Arms and Gates

One H100 job evaluates ordered primary, mean identity, gold identity, a globally different operation stream, and a globally different query field. Confirmation requires all of:

• ordered overall answer/state/chains >=97% / 97% / 95%;
• every ordered depth answer/state/chains >=95% / 97% / 93%;
• mean overall answer/state/chains >=90% / 90% / 82%;
• gold answer >=98%, exact state =100%, exact chains =100%, direction=100%, amount=100%;
• operation intervention covers every row, scores <=45% answers and <=35% state, and drops primary by >=50 / >=60 points;
• query intervention covers every row, scores <=5% answers, drops >=90 points, and changes state accuracy by <=0.1 point; and
• completed 0:0 receipt, zero fit updates, zero old-confirmation access, the exact training_lexicon_pointer_anchor_v1 protocol, and identical board, executor, and lexicon hashes in every arm.

No decoder, threshold, arm, seed, state, lexicon, evaluator, or gate may change after score. A pass confirms known-atom source-deleted recurrent execution through depth eight with externally supplied schedule/halt. It does not establish unseen-phrase semantics, plan induction, learned halt, free-form language reasoning, or novelty.

Closure

Replacement production seed 8548551866585932338 passed every corpus gate and created 2,048 rows / 6,136 chunks / 799,011 source tokens at board SHA-256 9fc73f9881a38d6fcd4624d411f34c6e1f7b8e879e0fef92405a7219ba481420. Job 693145 completed once on evc28, exit 0:0. Assessment SHA-256 cc1458f9962f4cda7cac5ea43555a3f8980e3adf24936b513ca3deb707d6e7f5 passes every frozen gate and records confirm_pointer_anchor_s3_v1_4_execution_through_depth_8. No rerun occurred. The local and Newton board copies are read-only and sealed.
