# R12 S3 Structural Pointer-Anchor Confirmation Result

**Decision:** `confirm_pointer_anchor_s3_v1_4_execution_through_depth_8`

This is the first strict independent confirmation of Shohin's bounded
known-atom, source-deleted categorical execution component. It is not a
confirmation of autonomous open-language reasoning.

## Custody

- Candidate source commit `51ed8fc`, public qualification commit `656f9b0`,
  and zero-score infrastructure receipt `ff553c1` all preceded the scored seed.
- Seed `223317486517061319` retired before board creation due missing remote
  imports. It has no score.
- Replacement seed `8548551866585932338` produced the sole scored board:
  512 quartets / 2,048 rows / 6,136 chunks / 799,011 source tokens.
- Board SHA-256 is
  `9fc73f9881a38d6fcd4624d411f34c6e1f7b8e879e0fef92405a7219ba481420`.
- Job `693145` completed once on H100 `evc28` in 84 seconds, exit `0:0`.
- Assessment SHA-256 is
  `cc1458f9962f4cda7cac5ea43555a3f8980e3adf24936b513ca3deb707d6e7f5`.
- Safe evidence archive SHA-256 is
  `1a65c5488de712d2ec235888249dee4bede089ab247f6f467546049c447eecdb`.
- No parameter fit, old-board access, decoder/gate change, or scored rerun
  occurred. Board copies are sealed read-only and are not in Git.

## Scores

| Arm | Answers | Exact state | All transitions | Direction | Amount |
|---|---:|---:|---:|---:|---:|
| Ordered primary | 98.242% | 99.658% | 98.975% | 100.000% | 100.000% |
| Mean identity | 92.773% | 92.920% | 88.086% | 100.000% | 100.000% |
| Gold identity | 98.535% | 100.000% | 100.000% | 100.000% | 100.000% |
| Operation derangement | 35.059% | 17.578% | 1.074% | 66.287% | 58.766% |
| Query derangement | 0.586% | 99.658% | 98.975% | 100.000% | 100.000% |

Every ordered depth passes independently. Depth-three is the minimum answer
cell at 97.384%; depth-eight is 98.235% answers / 99.412% state / 97.647%
chains. Operation replacement changes every row and drops primary by 63.184
answer points and 82.080 state points. Query replacement changes every row,
drops answers by 97.656 points, and leaves state exactly unchanged.

## Established Claim

On fresh known-atom referential programs through depth eight, the frozen source
compiler plus ordered categorical identity, threshold-free pointer-anchor
direction interface, closure-complete S3 action, and source-deleted recurrent
state produce causally field-dependent exact execution. The recurrence is not
recreating answers from an ignored schedule: replacing operations collapses
state and answers, while replacing only the query collapses answers without
changing state.

## Boundary and Next Bottleneck

The system still receives externally segmented operation chunks and an
externally determined stop. Its direction semantics cover the 12 exact training
atoms; unseen phrases fall back to a weaker neural head. Therefore it does not
yet establish autonomous decomposition, schedule induction, learned halt,
unseen-language generalization, or free-form reasoning.

Retain v1.4 as the locked execution baseline. Future work should attack
model-owned packet scheduling/halt and unseen action semantics on public data,
with this confirmed executor frozen. Do not reopen the sealed board or weaken
its claim boundary.
