Check a change for conformance with the repo's existing, pre-committed patterns and write a durable `conform.md` to `.ai/verify/` — a verdict plus drift findings, each a real `file:line` paired with the pattern it diverges from. A different axis from `dw-review`: fit with existing patterns, not internal quality. Read-only. Use when a change is ready to merge, or when someone says "does this match our patterns", "check for drift", "consistency check".
