R12 Conventional Complete-Compiler One-Shot Qualification Preregistration

Status: completed and passed once; exact result is frozen in R12_REFERENTIAL_LITERAL_POINTER_COMPILER_QUALIFICATION_RESULT.md

Question

The factorized development matrix showed that broad language coverage, not parameter islands, is sufficient for exact known-atom source compilation. The current sealed confirmation cannot be opened because the islands attribution gate failed. This board asks a narrower operational question without touching those bytes:

Does the already-selected favorable ordinary parser reproduce exact complete compilation once on a fresh, untouched known-atom board?

Frozen arm

• base: raw Shohin 300k, SHA-256 211d6b2cddf0c2cf8b12cb0b2d73f9c4440d85f6f531018080c8afd35b2f66a6;
• adapter: ordinary token tagger from job 693049, SHA-256 747a559b827c6d114943c091b9dea5b4b90cef7af13aa5003b8435c092d24991;
• adapter parameters: 8,607,886; total parameters: 133,689,550;
• no training, tuning, seed sweep, oracle, retry, or alternative arm selection;
• one evaluation only.

Board

• 2,048 semantic quartets / 8,192 rows;
• all language atoms occur in the public factorized training corpus;
• every complete factor combination is absent from public train, compositional-development, and lexical-OOD data;
• all entity and neutral-anchor names are absent from those public splits;
• zero exact-prompt and word-13-gram overlap against all public factorized data;
• canonical/paraphrase/order-twin/binding-twin and token-bag gates are unchanged;
• all ten source spans and both independent CPU executors must pass;
• the generator has no sealed-confirmation input or path.

The generator and this preregistration must be committed before the qualification seed is chosen. The report may expose counts and hashes before evaluation, but no row answer or model score may be read manually.

Gates

• answer accuracy >=99%;
• semantic-program exact >=99%;
• full ten-pointer exact >=99%;
• operation-kind accuracy >=99.9%;
• initial-state joint exact >=99%;
• at least 2,000/2,048 all-four exact quartets;
• zero confirmation access and every board structural gate passes.

Pass qualifies this exact conventional parser only as Stage-A infrastructure for a separately preregistered source-deleted executor/consumer development experiment. Failure rejects integration and requires diagnosis on this qualification board. Neither outcome establishes execution, halting, autonomous rollout, native reasoning, or architectural novelty.

Frozen outcome

The generator and this preregistration were committed at e7fa112 before seed 1218705082397710755 was selected. Job 693105 completed once on evc25 and passed every preregistered gate: answer accuracy 8187/8192, semantic-program and full-pointer exact 8186/8192, operation-kind accuracy 8192/8192, and 2045/2048 all-four exact quartets. The committed-before-score assessor records qualify_conventional_compiler_for_isolated_stage_b_development. This result does not authorize opening the old sealed confirmation or claiming execution, halting, autonomous rollout, native reasoning, or novelty.
