Contract and custody

V2 preserves the 146,057,595-parameter v1 system and changes only the model-logit discretization of the eight event-kind slots. It computes exact maximum a posteriori assignment under the public exactly-one-STOP grammar, exports the raw float32 8 x 3 logits, and lets the independent assessor recompute and verify the complete assignment. Only the resulting 25+1 categorical bytes reach the separate source-deleted executor.

The final board was generated only after source commit and after excluding all operation sequences from both inherited parent training and the consumed v1 development split. It contains 48,000 training, 2,304 development, and 2,304 sealed-confirmation rows. The sealed confirmation file remains mode 0600 and unopened. Board hashes are:

The cross-generation audit finds zero prior consumed-development prompt, name, or operation-sequence overlap in every new split; zero prior 13-gram overlap in new training and sealed confirmation; and 34 disclosed renderer-grammar 13-grams in new development. Confirmation access remains zero.

Training result

The treatment learns the complete consumed training interface:

• exact whole tape, initial state, kind, identity, amount, and query: 48,000/48,000;
• event pointer: 47,985/48,000; and
• exact STOP grammar on every treatment training row.

The equal-update independently row-shuffled-label arm remains near chance: 934/48,000 exact whole tapes, 1,361/48,000 identities, and 100/48,000 binding pointers. This is strong evidence that the projected treatment learned the fresh training binding function rather than inheriting or merely relabeling it.

Development result

All 672 exact treatment packets execute to the exact final state and answer: 100% conditional execution. Every frozen packet intervention matches its independently changed oracle, every observed STOP bucket is exact, source deletion passes, and negative controls remain below their ceilings. The recurrent motor, reader, state trajectory, halt semantics, and source-deletion boundary are therefore not the observed bottleneck.

Treatment compiler fields localize the failure:

Raw independent kind argmax already has exactly one STOP on 2,206/2,304 = 95.747% and exact complete kinds on 2,016/2,304 = 87.500%. Exact MAP adds one exact-kind row and guarantees legal construction, but it does not repair grounding.

Renderer and depth decomposition

Seven non-paraphrase variants each reach 288/288 exact recurrent state, while the held-out paraphrase renderer reaches only 39/288 = 13.542% state and 0/288 exact packets. All non-paraphrase variants are nevertheless stuck at 96/288 = 33.333% packets and answers because the late query is at chance.

State remains between 88.281% and 90.365% at every depth one through six. Packet accuracy instead follows the query-position alias: depths one/four are 62.5%, depths three/six are 25%, and depths two/five are 0%. This periodic structure, together with exact 33.333% query accuracy, is a direct label-position shortcut, not an execution-depth failure.

Pointers confirm the renderer failure. Source-line localization is 100% on all seven non-paraphrase variants and 0% on paraphrase; initial-entity localization is 100% on those variants and 14.236% on paraphrase; event-entity localization is 0% on paraphrase. The treatment's binding path is causally useful relative to shuffled supervision, but the common frozen source/query front end caps both treatment and consumed-projected arms.

Decision and next hypothesis

The frozen assessor records reject_projected_fresh_board; confirmation is not authorized. V2 establishes a bounded causal decomposition:

1. the model can learn the projected exact-surface binding function on fresh training rows;
2. a correct private categorical packet is sufficient and is consumed exactly;
3. renderer-invariant source grounding does not transfer to the held-out paraphrase family; and
4. the frozen late-query compiler is exactly at three-way chance.

Do not add executor width, epochs, a different STOP decoder, or a same-board rescore. The admissible successor is a fresh-board trainable source/query front end with renderer-orbit supervision and a content-addressed query-to-entity binding interface. The existing projected executor remains fixed. User authority permits the complete deployed system to grow only while remaining strictly below 200,000,000 parameters; parameter increases must be charged to this isolated front-end hypothesis and matched by equal-budget controls.

Preserved artifacts

Local mirrors preserve all seven files with these exact hashes. Development and confirmation custody is 1/0.
