weichen	c8f8076579	Make artifact backfill fixture a structurally valid docx ... Why: The backfill contract test used a fake PK-magic docx as its fixture; the new registration structural gate correctly refuses that shape, so the contract was no longer exercised. Evidence: The three affected runmgr tests pass locally with -count=1; the full combined suite receipt follows on the task card. Impact: Test fixture only; the gate behavior under test is unchanged.

weichen	aea948fd4d	Reject structurally broken OOXML at artifact registration ... Why: An agent bypassing the housestyle kit hand-assembled OOXML with zipfile; the resulting pptx lacked masters, theme and docProps. Text extraction succeeded and every existing check passed, so a package that Office refuses to open reached the user as a deliverable. Evidence: Focused Go suite covers a valid minimal pptx, the incident- shaped package, nine chain-break variants and register-level integration; the housestyle python suite adds BrokenPptxTests for masterless, kit-made and unopenable files. Full combined suite receipt follows on the task card before review. Impact: register_artifact now runs a pure-Go OPC structural check for docx/xlsx/pptx and refuses broken packages with a kit rebuild hint; lint_pptx gains structure-broken assertions (master/theme/layout chain, open-failure fallback) that template mode cannot downgrade; prompts forbid hand-assembled OOXML and specify the missing-library fallback.
