The CF→AWS data migration (closed 2026-05-16) is long done and the tooling isn't wired into any production path. Remove the one-shot binary, its support package, and the migration runbook. In live code, replace 'JS-parity' / 'same shape as JS' / 'cross-runtime KV migration' comments with the real, stable reason for each behavior (wire-format invariant, null-vs-zero distinction, CloudWatch alarm field name, etc.). 24 files touched across lolschedule, loldle, wordle, twentyq, trading, misc, util, server, metrics, ai, keylock. - delete cmd/migrate_cf_data/ - delete internal/migration/ - delete docs/cf-to-aws-migration-runbook.md
