- 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. - PR: PR-070
