Diff against the source claim by claim, not sentence by sentence. Where the rewrite says more than the original, the original wins unless the owner confirms the stronger claim in writing. Keep a record of reverted inflations so they cannot creep back in a later edit. ## Gate 2 — gaps: loud placeholders, never plausible guesses Facts the generator does not hold render as unmissable tokens — `[[TOKEN: question for the owner]]` — collected once into questions the owner can actually answer. Gate the build on an allowlisted token set so an unresolved gap is a build failure, not a shipped guess. A contradiction in owner-supplied facts holds the slot open; never resolve it by picking the convenient side. ## Gate 3 — parsing: re-extract and assert Rendering and parsing are different code paths, and a machine reader uses the one you did not look at. Any document destined for machine consumption gets verified by re-extracting its text and asserting: required strings present, banned strings absent, no glyphs outside the expected range — fail the build otherwise. The manual version: select all, copy, paste into Notepad. What Notepad shows is what the parser sees. ### Structure counts as parsing, not just text Re-extracting the text catches a wrong word. It does not catch a document that is structurally wrong while every word in it is right, and the reader sees the structure first. The worked case: a generator emitted a page break before the first paragraph, so **every** document it produced opened on a blank page. Nothing in the text was wrong. A recipient sees an apparently empty document, and for a client-facing report that is the whole first impression. ```bash python deliverable-integrity/scripts/check_docx_leading_break.py out/*.docx ``` Exit 0 when every file opens on content, 1 when any opens on a break, and it names which of the two causes it found because they need different fixes upstream. **The check that was contributed could not catch half its own subject, and that is the reusable lesson.** It tested for a page-break run (`w:type="page"`) and not for ``, which is what a paragraph style with "page break before" sets and is at least as common. Measured against fixtures on 2026-09-16, it passed a document that opens blank. When you inherit a verification script, put a known-bad artefact through it before you trust a green run: a check written from one instance of a bug tends to detect that instance and not the class (**prove-it-can-fail**). Generalise past `.docx`. For any generated artefact, assert the structural properties a reader meets before the words: a PDF's page count against what the content implies, a spreadsheet's first populated row, an email's first rendered line, a CSV's header row surviving the writer. These are cheap to assert and invisible to a text diff. ## What this skill does not do It does not verify code or history citations (verified-citations), police prose style (unslop-text), or substantiate marketing claims (substantiate-outward-claims). It keeps a generated document's factual content honest and its text layer machine-readable. ## Why A generated deliverable fails in ways a human proofread structurally misses: the page looks right while the claims drifted, the gaps got papered, and the text layer is junk to the parser that actually reads it.
