Conversation
Extends scripts/verify_package_integrity.py with --assert-vN-docx-changed mode. Asserts that v_(N+1) docx MD5 differs from v_N docx MD5; identical bytes = unmodified seed copy = block submission. Motivation: silent v_N → v_(N+1) docx copies (without regeneration via pandoc citeproc or Zotero CWYW field-code re-patch) cause markdown body edits to silently revert at portal peer review. Defense-in-depth gate. Adds Gate 10 + Phase 7 narrative to /sync-submission SKILL.md. Synthetic fixture tests cover identical/different/missing-v_N/missing-arg cases — all 4 pass.

PR T1-3: v_(N+1) docx MD5 ≠ v_N docx assertion
Title:
feat(sync-submission): add v_(N+1) docx regeneration gate (Phase 7)Summary
Extends
scripts/verify_package_integrity.pywith an--assert-vN-docx-changedmode that compares two docx files by MD5 andexits non-zero when they are byte-identical. Documents the gate in
/sync-submissionSKILL.md as Phase 7.Motivation
Cross-project precedent (anonymized): an outcome-MA submission package
at v_(N+1) shipped with a v_(N+1) markdown body change (two-paragraph
edit) but the v_(N+1) docx in the submission folder was byte-identical
to the v_N docx — a silent
cpover the v_N seed that never wentthrough the pandoc / Zotero CWYW regeneration step.
When uploaded to the EM portal, the markdown changes would have silently
reverted at peer review. P0 active submission blocker.
This gate adds defense-in-depth: even if the upstream regeneration
pipeline appears to have run, the byte-identity check catches the case
where it didn't.
