feat(ms-ai-architect): R20 — Category-backfill på 25 kategorisløse ref-filer via insertMetaField [skip-docs]
Ny testet primitiv transform.insertMetaField (anker + 500B-back-off som insertHeaderFields, idempotent på eksakt label, body byte-identisk; 6 tester) + backfill-category.mjs (deterministisk folder->category-regel, hard per-fil-invariant, insert-only, aborterer for skriving ved avvik).
Fordeling: 14 Solution Architecture & Advisory (architecture/), 6 Microsoft AI Platforms (platforms/+development/), 4 Responsible AI & Governance, 1 MLOps & GenAIOps. Label = engelsk Category (322 vs 42 Kategori). Eksisterende recommended-mcp-servers/rag-maturity-model urort.
Roadmap: R20 done + R21 (Status/Last-updated not-due) encoded. Verifisering: 0 kategorislose filer (var 25); diff +25/-0; idempotent re-run; suite 764/764 exit 0.
