1. POC edits LOFI Doc in Suggesting mode
2. Each suggestion = textRun with suggestedInsertionIds / suggestedDeletionIds
3. POST /api/install/sync-edits { brand_slug }
4. Parser walks doc paragraphs · tracks current ▸ FIELD context · classifies:
   · score / notes / field_label / content / pure_delete / pure_insert
5. Applies edits to brand.config.engine.components[slug] per field path
6. Field-context fallback: if before-text drifted, overwrite by field path
7. Returns { applied, captured, skipped, report[] }
8. POC reviews report · re-fires Doc gen if needed

At gen time for each fresh-gen component:
1. Pull rated 4-5/5 references from library table (Reviewer-curated)
2. Slug aliases (e.g., landing → landing, landing_page, marketing_website)
3. For each ref: Claude extracts headline_pattern, cta_pattern, structure_pattern,
   voice_pattern, trust_pattern, anti_patterns_observed
4. Inject patterns into prompt as RULES (not verbatim examples)
5. Cache patterns in PATTERN_CACHE (in-memory session)
6. Output reflects patterns applied to current brand's voice
