# 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.
