- dual_write / shadow_read no longer write flat in the update_/add_/
delete_{type}_metadata pre-filters, before WP decides whether native
changes at all. added_/updated_/deleted_{type}_meta (priority 1) call
TMDO_Hook_Bus::sync_from_native(), which copies the entity's first native
row (plain SQL, NULL when gone) into flat. Flat now follows native when WP
skips (same value), refuses (non-matching prev_value, add $unique on an
existing key) or deletes (also delete_all: touched IDs are collected from
the meta IDs in delete_{type}_meta), and a flat value left stale by a
direct SQL write heals on the next write.
- update_metadata_by_mid key changes: the old key is remembered in
update_{type}_metadata_by_mid and re-synced too.
- wpdo_after_write / wpdo_after_delete fire from the sync with the same
arguments; aeav_only keeps the pre-filter short-circuit unchanged.
- $internal_ops lock key includes the entity type (user 5 ≠ post 5).
- Live suite resync: 4 entities × 2 modes × 3 scenarios (old code: 16 of
24 FAIL); integration: pre-filter leaves flat to the sync, delete_all
re-syncs every touched user.
- Verify: live resync + shadow_write + serialized + zero_side_effect 33/33
PASS; unit 687 OK, integration 485 OK, phpcs (phpcs.xml) 0, stan OK
