fix(export): make DOCX export produce real DOCX everywhere (DA-05) - #520
Conversation
Selecting DOCX in AdvancedImportExport's export dropdown silently
produced a Markdown file mislabeled .docx — its handleExport fell
through to the same branch as Markdown. FsProjectStore.exportProject's
'docx' case had the identical bug and, per a reachability check, zero
production callers and no binary-write API to ever do better, so it's
removed rather than half-fixed.
Extract the Document-building logic already used correctly by
useExportView's downloadDocx into a shared, renderer-independent
services/export/docxDocumentBuilder.ts, and route both real UI export
paths through it. Invariant: selecting DOCX produces a valid DOCX
payload, or DOCX is not offered — never silent Markdown.
Along the way: fixed a latent test-mock bug (`Document:
vi.fn().mockImplementation(() => ({}))` — arrow functions can't be
constructors, so `new Document(...)` was throwing and getting silently
swallowed) and a `vi.stubGlobal('URL', {...URL})` pattern that replaces
the real constructor and breaks Vite's own dynamic-import resolution;
both were previously masked by assertions too weak to notice the docx
path wasn't actually running.ⓘ Qodo reviews are paused because your trial has ended. Ask your workspace admin to add credits to resume reviews. Manage billing |

Summary
This PR successfully fixes the DOCX export bug (DA-05) where selecting DOCX format silently produced Markdown files mislabeled as .docx. The fix is well-architected and thoroughly tested.
Key Changes
✅ New shared builder (services/export/docxDocumentBuilder.ts) - Extracts DOCX document creation logic into a pure, reusable function
✅ Fixed export handlers - Both AdvancedImportExport.tsx and useExportView.ts now delegate to the real DOCX builder
✅ Removed broken code - The 'docx' case in projectFsStore.ts had zero production callers and incorrectly produced Markdown
✅ Comprehensive tests - 7 new tests verify genuine DOCX output by checking ZIP signatures (PK\x03\x04)
✅ Test mock improvements - Fixed pre-existing mock issues (arrow function constructors, URL stubbing)
Architecture
The extraction of buildDocxDocument() as a shared utility ensures consistency across all export call sites and prevents future regressions. The PR description clearly documents the invariant: "selecting DOCX produces a valid DOCX payload, or DOCX is not offered — never silent Markdown."
All code is working correctly and ready to merge. No blocking issues found.

Address chatgpt-codex-connector/CodeAnt AI review of #520: - FsProjectStore's TauriApis does have a binary-write API (writeFile(path, data: Uint8Array)) — my prior commit's comment claiming otherwise was wrong. Implement real DOCX via buildDocxDocument + Packer.toArrayBuffer + apis.writeFile, instead of removing the 'docx' case. Packer.toBuffer (Node Buffer) would break in the Tauri WebView, so use the browser-safe toArrayBuffer/Blob path already proven by the other two call sites. - Add a behavioral test (tests/unit/services/fs/fsStores.test.ts) asserting the written bytes carry a real ZIP local-file-header signature, using the existing fake TauriApis' bin: Map<string, Uint8Array> writeFile tracking. - Add the QNBS-v3 rationale comment CodeRabbit asked for on useExportView.ts's buildDocxDocument call site. Filed #521 for the two "Major" feature-parity findings (DOCX omits characters/worlds/compile-profile, ignores the title toggle) — verified via `git show origin/main:hooks/useExportView.ts` that this predates this PR entirely (present since at least 526b37f); out of DA-05's scope (DOCX *format* correctness, not feature parity between export formats).

Address CodeRabbit review of #520: the DOCX export's "Logline"/ "Manuscript" labels were hardcoded English. Use getStaticTranslation (services/i18n/staticTranslate.ts) — the existing middleware-safe i18n accessor for code that runs outside React — for export.loglineLabel and export.manuscriptLabel, both already-existing keys in every locale bundle. Strengthened the DOCX behavioral test to assert the translated labels actually appear in the generated document.xml, not just the ZIP signature.

Writing a behavioral test that actually asserts
Packer.toBlobwas called (rather than just "loading settled") surfaced two pre-existing, silently-broken test-mock patterns intests/unit/hooks/useExportView.test.ts(not introduced by this PR, just newly exposed by a stronger assertion):Document: vi.fn().mockImplementation(() => ({}))— arrow functions can't be used as constructors, sonew Document(...)inside the builder threw, previously masked by an assertion that only checkedisExportLoading === false(true whether the docx path succeeded or silently failed).vi.stubGlobal('URL', { ...URL, createObjectURL: ..., revokeObjectURL: ... })— replaces the realURLconstructor with a non-constructible plain object, which breaks Vite's own dynamic-import module resolution (new URL(...)internally). Fixed by spying on the two static methods (vi.spyOn(URL, 'createObjectURL')) instead of replacing the whole global.Both fixes applied to
