R12 S4 Self-Delimiting Event Tape Result

Decision

REJECT_S4_V1_AND_V1_1; retain one causal discovery. The treatment learns exact autonomous event count on every public-development source and, whenever it emits a structurally valid tape, the entire program/state/answer is exact. It misses the frozen 95% overall program gate by 14 rows. The zero-fit pointer-anchored v1.1 repair collapses on variable-width referential boundaries and is also rejected. No confirmation board was generated or read.

Frozen objects

• Immutable base: 125,081,664 parameters at the protected 300k checkpoint.
• Parser adapter: 8,608,271 parameters; total 133,689,935, below 150M.
• Training: 48,000 whole-source rows, depths 1--4, 120,000 events, one epoch / 750 updates.
• Development: 2,048 matched rows, depths 3--8, zero train/development exact, 13-gram, name, or factor overlap.
• Treatment training job 693152; shuffled-label control 693154.
• Original evaluations 693153 and 693155; diagnostics 693157 and 693158.
• Pointer-anchored evaluations 693160 and 693161.

Original autonomous result

All 1,932 valid strict tapes have the exact program, state, and answer. Strict treatment program by depth is 97.093%, 94.767%, 94.706%, 94.118%, 90.294%, and 95.000% for depths 3--8. The failures are 66 intro-cardinality, 47 event-component-cardinality, and three entity-identity errors. Gold intro/query boundaries raise every depth to at least 96.471%. This supports learned variable event count and event semantics, while localizing the remaining miss to source-span emission.

Frozen zero-fit repair and rejection

Source/prereg commit 34657ea and corrected training-width receipt commit 36f06ed precede any v1.1 score. The first training-only lexicon build failed closed because it incorrectly required one entity width; contextual BPE spans are widths 4/5/6. Its rejected SHA-256 is f487d1cb98bebd84137c1b0b7839e2241603cc4f920f4f1a09205f502e9015e6. The lawful set-valued receipt passes all gates at SHA-256 eb49f75d969c999d4bcb8f2e350658f76a5491d4a91a7e4abff83b086ba4fd38.

The pointer-anchored treatment preserves exact count at 2048/2048 but falls to 25/2048 = 1.221% exact programs and 300/2048 = 14.648% answers; shuffled remains 0/2048 programs. Treatment has 1,176 event_entity failures and only 306/2048 exact initial rosters. A global token-role maximum cannot determine the correct 4/5/6-token boundary, and shared event-role scores do not pair each direction anchor with its own entity as depth grows. Assessment SHA-256 fd0479b0737af49313b0cebf1863c4826c21de336f51e240ece3e4d60d11d587 records reject_s4_v1_1_public_development.

What survives

S4 v1 is the first whole-source result here to recover the exact number of complete known-atom events on all 2,048 held-out rows without padding, host count, or hidden active_operations. Shuffling supervision destroys the result. The locked S3 executor is not the bottleneck once a tape is valid. The open interface is now narrower: variable-width start/end binding and event-relative argument pairing.

Next admissible experiment

Do not tune another deterministic decoder on this public board. S4 v2 must replace shared token-role segmentation with learned start/end pointers for the three roster entries and event-relative pointer queries conditioned on each model-found direction anchor. It must retain source-order count, train only on depths 1--4, and evaluate once on a newly frozen, disjoint development board through depth eight. A favorable parameter-matched shared-role parser and shuffled-label arm remain mandatory.

Claim boundary

This is evidence for bounded known-atom schedule counting and conditional tape execution, not a confirmed autonomous parser, semantic halt, unseen action semantics, planning, open-language reasoning, benchmark improvement, or architectural novelty.
