- 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.

- TMDO_Type_Caster: text / textarea values that are arrays or objects are
stored with maybe_serialize() (was (string) → the literal "Array", which
bridge-restore-native then wrote back over native meta); from_db()
unserializes them with TMDO_Safe_Unserialize. text columns are
VARCHAR(255): longer values are stored NULL (native keeps them) and
logged as text_overflow.
- Add `wp tmdo repair-array-literals [--entity] [--confirm]`
(TMDO_Array_Literal_Repair): rewrites flat "Array" values from native
meta and lists native rows that are "Array" themselves (backup needed).
- Verify: TypeCasterSerializeTest 13 OK, ArrayLiteralRepairTest 3 OK;
unit 685 OK, integration 483 OK, phpcs (phpcs.xml) 0, stan OK;
live `serialized` 3 PASS; dev36 repair dry-run lists the value corrupted
by the 2026-09-26 round trip (user #1 community-events-location)
