  "description": "#439 scholar-declared document LAYOUT profile (spec docs/design/2026-06-15-439-format-profile-design.md). Consumed by the Phase 7 formatter_agent (a RENDERER, 'how should this look'), NOT a verifier — kept separate from venue_profile by design (decision B). Declared-only rule (downgraded, §3): the formatter follows ONLY the supplied fields and NEVER infers a missing layout field from the venue name, institution, language/locale, or filename — the reason is consistency/reproducibility, NOT integrity, so this carries NO provenance machinery (no declared_by const, no _inferred lint). Omission of a field = NOT-DECLARED = the formatter uses its current prose default for that aspect (byte-equivalent to pre-#439 when the whole profile is absent, §5a). Venue compliance constraints take precedence over these rendering preferences (§3a). Each field is best-effort per output target (DOCX/PDF/LaTeX), §5c.",
