From bc97ccebf07d51d6744b1ca2a7d3b504a0cb7b93 Mon Sep 17 00:00:00 2001 From: Steven Obiajulu Date: Mon, 8 Jun 2026 12:50:37 -0400 Subject: [PATCH 1/2] test(docx-core): wire a LibreOffice accept/reject oracle voter into the differential harness MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Lean↔TS helper differential proved the model and the engine AGREE, but had no independent ground truth. This adds LibreOffice — the native engine for the .uno:Accept/RejectAllTrackedChanges dispatches — as a third voter, so the paragraph-collapse claims (G3/G4/G5 + the mark-based drop rule) are oracle-backed. New committed helper packages/docx-core/src/integration/libreoffice-oracle.ts: resolveSoffice, packMinimalDocx/extractDocumentXml (reusing primitives/zip), runLibreOfficeOracle (drives LibreOffice headless via an injected Basic macro — pyuno is blocked on macOS — batching all jobs in one launch), and paragraphShape. Gated voter [LEAN-HELP-09..11] in lean-differential-helpers.test.ts asserts LibreOffice agrees with the TS engine on paragraph STRUCTURE (count + which paragraphs collapsed to empty), not the full token projection: - [09] kept-not-dropped on G3/G4/G5; the contrived nested ins[del] G3 content divergence (LibreOffice keeps the inserted-then-deleted text on accept, where Word/Lean/TS collapse to empty — a likely LibreOffice nested-redline limitation) is pinned, not hidden. - [10] full structural agreement on the clean single-level fixtures (G4/G5). - [11] a PPR-INS-reject / PPR-DEL-accept drop control (the other direction). Local-only and best-effort: resolveSoffice only checks a binary EXISTS, not that it can LAUNCH. CI installs no LibreOffice (skips), and LibreOffice aborts (SIGABRT) under a sandboxed shell — so beforeAll catches a launch failure, logs why, and the assertions no-op rather than fail. A real terminal with a working LibreOffice runs it fully. The macro driver waits out the single-instance lock + retries once; SAFE_DOCX_ORACLE_DEBUG=1 keeps the temp profile for debugging. No production-engine change.

Confirmed by `[LEAN-HELP-08]` (now agreement) plus a targeted both-paths-agree regression over four shapes. With G5 closed, every characterized G-case (G1–G5) agrees between the genuine Lean helpers and the production engine; no KNOWN gap remains in this harness. `extractText` / `normalizeText` are **not** modeled in Lean Tier 2 and are deferred to a further increment (`add-lean-ts-text-extraction-differential`). +- **LibreOffice accept/reject oracle voter — LANDED** (`add-libreoffice-accept-reject-oracle`): the paragraph-collapse cases are now validated against a real reference implementation, not just Lean↔TS self-consistency. A committed helper (`packages/docx-core/src/integration/libreoffice-oracle.ts`) drives LibreOffice headless through the native `.uno:Accept/RejectAllTrackedChanges` dispatches (Basic-macro injection; pyuno is blocked on macOS) and a gated voter (`[LEAN-HELP-09..11]`) asserts LibreOffice agrees with the TS engine on paragraph structure: the untracked-mark paragraph is kept (G3/G4/G5), the clean single-level fixtures collapse identically (G4/G5), and a `PPR-INS`/`PPR-DEL`-marked paragraph is dropped. The comparison is structural (paragraph count + emptiness), not the full token projection — LibreOffice rewrites styles and interprets the contrived nested-revision G3 case differently (it keeps the inserted-then-deleted text), a divergence pinned in `[LEAN-HELP-09]` rather than hidden. **Local-only**: gated on a LibreOffice binary; CI does not install one, so it skips there (like `odf-core`'s LibreOffice round-trip). Rough effort: **2-6 months** combined (the harness above is the first slice).
