- Copy route: drop WordPress's GROUP BY when the flat row is the only join,
and read posts.ID tie-breaks as the flat post_id (own direction, once)
- Post status sync: index (post_status, post_date, post_id) replaces the
two-column idx_post_status_date (added / dropped by post-status-sync)
- dev36, 235k of 1.3M listings in a price range: main query 1.7 s -> 3 ms
- Verify: composer test (704), test:integration (597), phpcs, stan
- PR: PR-128
- migrate_entity() (drift-check --fix, per-row backfill) REPLACEs the whole
flat row and left out the post_status / post_date copies, so a rebuilt row
had NULL status. One such row turns the status/date copy route off for the
whole group: on dev36 a single row rebuilt by the stage-3 drift fix made the
date-ordered price search 1.47 s instead of driving from the flat index
- post rows now carry TMDO_Post_Status_Sync::insert_columns(); the bulk pivot
backfill (ON DUPLICATE KEY UPDATE) was not affected
- Verify: PostStatusSyncTest (existing and new rows keep their copies),
integration 593, unit 704, phpcs, stan; dev36 post-status-sync + front-end
- PR: PR-127 (found in 2.4 profiling)
- on_transition() skips a recorded group whose table no longer exists and
removes it from tmdo_post_status_columns; every post status change used to
UPDATE the missing table and print a database error (seen on dev36 after a
throwaway group's table was dropped)
- Verify: PostStatusSyncTest (dropped table), integration 578, unit 701, phpcs, stan
- PR: PR-106
- 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

- TMDO_Post_Status_Sync: post group tables get post_status / post_date
columns (posts' collation) and an (post_status, post_date) index.
Brand-new empty tables get them on creation; existing tables only via
`wp tmdo post-status-sync [--dry-run] [--batch]`, never as DDL on a
populated table in a web request. Per-group state in
tmdo_post_status_columns ('columns' | 'ready').
- transition_post_status refreshes the copies; Hook Bus upserts that
create a post row fill them in (existing rows keep theirs).
- Bench (1M rows): add columns 0.05 s, index 5.3 s, batched backfill 32 s,
0 mismatches afterwards.
- Verify: core unit 659 / integration 466 green, phpcs clean
