Audit current R437 whole-word translation under retained physical contracts

[Clear1nsight]

Current-source contribution

Extends Nick Petalas's #2989 compiler-correspondence audit to the complete current R437/OQ4 event skeleton at #3647 head a24f9ff. New package: research/r437-whole-word-refinement; no shared-code or selected-frontier changes.

• Actual retained Driver versus actual compiler/dispatcher: 288 calls, 903,456 residual sites, 7,035,840 ordered local/family XOR input-output triples, 29 global checkpoints and 12,336,607 emitted symbolic macros, at one formal low label. All arbitrary initial family contents remain symbolic. Each disposal and final staged/private cleanup is checked.
• Five semantic mutants reject, including destructive clone, lost private output, stale scatter, omitted private disposal and reversed XOR roles. Tiny two-low tests cover both mode0 and mode1.
• The unchanged Machine.run loop is exercised under explicit recursive-cut contract actions at depths 0,1,2,17. This adds loop-composition coverage; it does not execute physical CALL/RETURN.
• The conditional ordering theorem and omitted-owner admission guard are credited restatements of Independently audit selected compiler ordering and owner guards #2989, not new discoveries. The useful delta is current R437/OQ4 whole-source coverage beyond its eight reduced GL2(F3) words.

Qualification

This is a differential source-reuse check and a conditional theorem adaptation, not an independent numerical implementation. The compiler's append-only list is streamed in the checker to bound memory; branches and emitted operations are unchanged. Packet operations and residuals are opaque expression constructors. One formal low does not enumerate GL64; abstract good-block residual symbols do not test real good/fallback bodies. Primitive algebra, high fields, full production volume, source/stock/history, physical parking, time/visited-space, precision and ordinary/native/router premises remain open. No supplier admission or new kappa.

The paired operational-semantics/separation-relation and algebraic-expression approach isolates exactly this composition layer. The sibling transport/resource lanes remain separate contributions, not automatically admitted dependencies.

Validation and pins

Canonical main and priority revision6: 20ecf28. Both retained R437 files match their exact upstream a24f9ff Git blobs, also retained through #3936. PR3967 CI was checked PASS before this round. Full local symbolic generation: CPython3.12.3,234.03 seconds,208340 KiB peak RSS.

Registered replay, optimized semantic controls and actual Git-free quick export pass. The export run is deliberately the bounded quick scope. Changed compiler/template, missing word and symlinked dispatcher controls reject. Reproduce:

python3 -B scripts/research_package.py --package research/r437-whole-word-refinement

SOURCES/TASK/VERIFY retain exact provenance, scope and commands. No historical full replay, Lean or Docker was run. Hosted CI is reported separately from local success.

Coordination and credit

Explicit user assignment refines independent-moment; team claim: #3967 (comment). Live overlap found #3967/#3950/#3936/#3724/#3690; the team then found and read canonical #2989, and narrowed the novelty claim accordingly. Search coverage is partial, not a novelty certificate.

Nick Petalas/#2989; Jose Manuel/#2809/#2195 and numerical/ordinary lineage; David Arias/#2753; ywz65 parking/staging; ai-nanachi R437/OQ4; zxv/#3690; Ali Romman/#1043 and retained helper/native/compiler/owner/outer contributors. Chris R/Clear1nsight's #3936/#3950/#3967 source/stream/return audits are predecessor context. New source audit, adaptation and packaging by Chris R with substantial OpenAI Codex assistance. Full notices and attribution are in the package.

Open next questions: independently admit actual current chart separation; prove complete residual and recursive-cut contracts; attach the complete physical cost and visited-cell invoice without omitting the rest of the rank26 child or double-counting its internal rank7 COPY.

Publication head a693da700af272252d701b36614922fd838efdd2 passes exact 26-file package/input byte and canonical source-history verification plus whitespace checks. All three registered commands passed. Retained notice and input bytes preserve their original line endings. The separate current chart certificate is now public in PR #3980; it remains subject to its stated scope and review.
