# UTM cleanup — archived analysis (2026)

**Last Updated:** 2026-04-01

Completed UTM migration/cleanup research: executive summaries, risk/cost, rollback, and implementation notes. Operational runbooks remain under `docs/development/UTM_CLEANUP_*.md` and `docs/monitoring/`; they link here for deep-dive references.

All files in this folder were moved from `docs/analysis/UTM_CLEANUP_*.md` so `docs/analysis/` keeps **active** engineering notes (blog CSS, comparison tables, etc.).
