- TMDO_Drift_Check::fix() deletes flat rows of deleted entities and, for post groups, of posts outside the group's post types; rebuilds every other drifted entity's row from native through the new TMDO_Entity_Migration_Engine::migrate_entity() (keys without native rows become NULL, PR-066); keeps a row whose entity has no native value for the group but clears its columns (no NULL-only inserts, no deleted rows the router may join on); invalidates the row cache of each touched entity; then checks again. Native meta is never written.
- `wp tmdo drift-check <entity> --fix` (not combinable with --sample).
- Verify: DriftCheckTest fix cases (RED: method missing); dev36 --fix: post 42 rows rebuilt, 1 stray row (post 312, hp_booking in hp_draft_flags) deleted, all four entities 0 drift after, checker miss/extra 0.

- New TMDO_Drift_Check compares every backfillable group of post / user / term / comment with native meta by value (first native row → safe unserialize → Type_Caster::to_db): miss / diff / extra per key, set-based SQL with BINARY exact matches, PHP comparison only for the remaining candidates. Serialized-vs-JSON and 50 vs 50.000000 are no longer drift; over-long text stored as NULL is not a miss; extra covers rows of other post types. Outcome per group goes to the wpdo_drift_status option; nothing else is written.
- `wp tmdo drift-check <entity> [--group] [--sample=<n>] [--format]`. A new class instead of extending the post-only shadow verifier, which queries row by row and writes shadow_diffs.
- Verify: DriftCheckTest; live suite drift; dev36 post miss=533 diff=2 extra=1 in 23 s (checker's 45 json false diffs gone), user/term/comment 0.
