Research: independently check semantic-D bridge for composed R439 word

[Arham-Tahir64]

PR1194's proposed semantic-D substitution contract is applied there to the 11,500-ADD PR1062 word. PR1122 changes A and cleanup as well, and retains the H2/K interface-adoption obligation. This package independently checks the contract's exact antecedents on PR1122's pinned 10,652-ADD candidate, including the unchanged chronological continuation after a proof-only original-D prefix.

The independent set-valued calculation covers all 661 arbitrary dirty input columns: semantic D compensation equals the raw continuation's K, with V=J=I and no target contribution to the source/helper block. The original-D splice passes every original H1–H5 and U/J/K/C flag through the unchanged owning checker. The actual candidate retains exactly its documented syntactic H2/K failures. The README gives the inherited substitution argument and names its common-frame assumptions. This is a scoped application of the predecessor's proposed proof, with no new circuit, saving, or κ.

Complete forward/reverse COPY/ERASE replay and local recount agree with the predecessor: 10,652 ADDs, D 5,548; nine rank-seven copies/erasures; rank mass 5,129; identical ordered frame paths; F=15,223, B=3,910,388; strict 92/176-bit envelopes below the retained 104/192 caps. Nine mathematical controls reject dirty-restoration, compensation, source/target response, forbidden operand/frame and stale-cleanup faults. The stale cleanup passes the binary endpoint but fails H4, demonstrating why the bridge cannot be inferred from endpoint equality alone.

Sources, task and overlap

• Start: current main bce54fb3f895cbe5cd4c0eb477c3afeed100190f.
• PR1122: a2551e70fce0cc34348f50f1a94e7cc4c80bbcbf; exact candidate blob 0ab597fefd68bfefecc85d631b172d174bdaeb70 copied with original notice/license. PR1194 proof: 2e39c98238f543d988f9efc1b076590a4b780dca. Both heads rechecked unchanged.
• Card bit-helper-contract, refined; OS nonce 09c41251dd3913927a6d642281ba7824, priority revision 2. TASK.json records scope, sources, stop rule and follow-up.
• Refreshed overlap helper at 2026-10-13 22:24 UTC: 803 open PRs including drafts and 53 Discussion records, complete pagination. Literal searches exclude arbitrary diffs/nested sources and do not prove novelty. PR1194 owns the lemma; PR1122 owns the candidate and its native replay, including the PR1062 corner. PR1208 changes the word further; PR1306/discussion1290 instead examines target feedback. This independent check preserves H1.

Validation

python3.12 scripts/research_package.py --package research/r439-abc-semantic-bridge
python3 -B -m unittest discover -s tests -p 'test_research_*.py'
python3 -B scripts/research_baseline.py

All pass: registered replay and optimized relocation/corruption subprocess tests; 20 research tests with one skipped; selected-source bindings. Python 3.12.14 matches the deterministic receipt generated under Python 3.14.7. Three real package corruptions are rejected. Metadata/pins and staged whitespace checks pass.

Native replay, changed-word hosted emission/invoice, all-size compiler/common-label realization, precision/tape, recovery, analytic transfer and proof-assistant formalization are not executed or established here. PR1122's native evidence is credited, not freshly reproduced. Supplier adoption requires maintainer acceptance of the replacement interface and complete physical evidence; the selected frontier is unchanged. README/TASK give the concrete hosted-admission next question.

100-PR batch review at a2875c1834b9c9ef42a84eda4890d5462cc98fa5.

Merged to main, preserving the original contributor commits and package attribution.

Reviewed scope: Semantic D-bridge audit of the retained PR1122 module, with virtual-prefix H1–H5 checks and two explicitly exposed syntactic failures. Local binary module verification is distinct from whole-supplier acceptance.

The pinned scoped command passed; the batch ledger contains its command, input hashes, environment and log. This incorporates the research/tooling contribution and does not change the selected κ or discharge the inherited multiplication-theorem assumptions.

Batch review, attribution and evidence. Thank you for the contribution.
