R12 S3 Lexical Closed-Action Confirmation Preregistration

Status: closed after one scored production board; strict gold-exact gate failed, so the confirmation is rejected and the board is sealed.

A scoreless 512-group mechanics validation used seed 1, passed every data and derangement gate, and was deleted before this freeze. Seed 1 is retired and cannot be the production seed.

The first production-generation attempt at seed 3906227011763392781 was rejected before model access because query derangement was infeasible at depths 3 and 6. No score exists. That seed is retired. The sole mechanical correction cycles required query positions 0/1/2 within every depth and resamples semantics until the requested position separates both twins. It changes no row count, factor/name policy, evaluator, score gate, model, or intervention. Corrected scoreless validation seed 2 passed every gate and was deleted; it is also retired from production use.

Confirmed object

The candidate is the exact public-development system from commit a2fc8da and assessment 41102547...: frozen ordinary source compiler, training-only 12-pattern direction lexicon, ordered relational identity primary, frozen amount/query heads, and closure-complete categorical S3 action/state. No weight will fit the confirmation board.

Fresh board

After this source/prereg is committed, one unpredictable production seed may create 512 new semantic quartets / 2,048 rows balanced across depths 3--8. The generator excludes every factorized train/development and relational-public prompt, word 13-gram, entity name, and factor combination. All names are fresh paired nonces. Every active direction span must be one of the 12 training lexicon atoms. CPU pop-insert and adjacent-swap executors must agree. Operation and query strata must each admit a semantic derangement within every depth. Any generation failure retires its seed before score.

The earlier failed RGDE confirmation is forbidden as an input and remains sealed. Only public data and the committed training lexicon may define the new board.

Frozen arms and gates

One H100 job evaluates, in order:

ordered identity primary;
mean-vector identity conventional control;
gold identity ceiling;
globally different operation streams with ordered identity; and
globally different query fields with ordered identity.

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, and identical board/executor/lexicon hashes in every arm.

No threshold, arm, seed, state, lexicon, or evaluator 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

Corrected production seed 3664953321459551042 passed every board gate. Job 693138 completed once on evc25, exit 0:0. Ordered primary reached 99.121% answers / 99.268% state / 98.682% chains and all non-gold gates passed. Gold reached 99.609% answers / 99.951% state / 99.902% chains because two of 11,248 direction decisions were wrong. The frozen 100% state/chains requirement fails; assessment 8d69dd5d... records rejection. No rerun or threshold relaxation is allowed. See R12_S3_LEXICAL_CONFIRMATION_RESULT.md.
