# R12 S5 Learned Generator-Factored Confirmation Preregistration

**Status:** frozen after S5.2 development qualification and before confirmation
seed, board, or access.

Job `693183` completed the sole S5 development read with all gates passing.
The unchanged learned arm scored 97.510% exact programs, 98.193% exact state,
and 98.682% answers, exactly matching the quarantined host executor on state
and answer. It achieved 36/36 unit and 36/36 held-out amount-two transitions.
Deranged law, direction rotation, and state reset scored 19.336%, 1.709%, and
43.311% state. The generator has 4,934 parameters; total system size is
133,694,869. Development evaluation SHA-256 is
`8e20728f13a011c8e5a424cc8dbd52fccc9b9df93cb3f69ab39ed877c689ba37`.

## Frozen Confirmation

The exact treatment/shuffled checkpoints, parser, base, program-only decoder,
five execution arms, closure audit, assessor thresholds, and all claim
boundaries remain unchanged. Confirmation-only code may change only:

- admission of a report marked `board_role=confirmation`;
- access accounting from development 1 / confirmation 0 to development 0 /
  confirmation 1; and
- the final decision label.

After this source is committed, draw one seed and build one 512-group board
excluded against source training and every public/development S4/S5 board.
Never open any prior confirmation bytes. The board must pass all existing
corpus gates before exactly one serial H100 read. No fit, retry, repair, second
seed after a passing corpus, threshold change, or rescore is allowed.

Every original S5 gate remains required, with only the access-accounting gates
changed as above. Passing confirms bounded learned generator-factored execution
behind the frozen known-operation S4 v5 parser. It still does not establish
unseen operation semantics, open-ended planning, learned termination,
unrestricted language reasoning, or full standalone native reasoning.

## Frozen Board

Seed `2190224777450473319` yields 2,048 rows / 512 groups over depths three
through eight, maximum 339 tokens. Every exclusion, balance, context, and
independent-executor gate passes; prior confirmation bytes were never opened.
The board is bound to development qualification SHA-256
`421a27fbcf6d4eb5e2084f2d01048963dbe0cafb7664bdbcf4c76cc9035c6f44`.
Confirmation data SHA-256 is
`7786919b6d284c359e434783638dcaed96d1c654c6e9174566c4e76767d73fc0`;
report SHA-256 is
`7d2ad6f5e08558dc862feed3b0ee5d885a3e788798e6e3d207afdae50a605b29`.
Newton and local copies are read-only. Commit this receipt and aggregate report
before exactly one H100 read; no replacement board or retry is authorized.

## Closure

Sole job `693185` completed once on H100 `evc24` in 36 seconds, exit `0:0`.
The unchanged learned arm scores 96.924% exact programs, 97.607% exact state,
and 98.096% answers, exactly matching the host upper bound. It retains 36/36
unit and 36/36 never-trained amount-two closure. Fixed-deranged, direction-
rotated, and state-reset controls score 22.217%, 1.807%, and 40.234% state.
Every gate passes; assessment SHA-256 is
`165b1a9ae40c8b3f52d133983c21fb22bfa2f2507b30a318f86106c96e6abc4e`.
The decision is `confirm_s5_learned_generator_factored_execution`. No rerun,
repair, second board, or post-confirmation fit is authorized.
