Production Documents

1. Read ../../references/PRODUCTION_DOCUMENTS.md and the authoritative project artifacts for the requested document.
2. Add a DOC-### record to 00_project/document_manifest.json.
3. Use project-relative source and output paths.
4. Use XLSX for structured tracking/calculation, DOCX for editable prose/tables, and PDF for fixed delivery/review.
5. Keep formulas as formulas and label assumptions.
6. Create documents with scripts/production_documents.py; it must also create the same-basename Markdown companion beside every XLSX, DOCX, or PDF output.
7. Read ../../references/DOCUMENT_COMPANIONS.md and run scripts/document_companions.py audit before delivery. Run structural QC and, where available, recalc or visual preview checks.
8. Add public-facing documents to the release manifest when requested.

Done when the rich document and its human-readable Markdown companion both exist, the document opens structurally, and both are traceable to the same project sources.
