- Add tests/live: a `wp eval-file` runner (PASS/FAIL/XFAIL/XPASS/SKIP) with
fixtures that override entity modes in process (pre_option) and read
native / flat values with plain SQL, so WP core meta flows run for real
- shadow_write suite reproduces the dev36 finding: in shadow_read,
update_*_meta returns false and native meta is never written
(3 XFAIL marked for PR-056); the dual_write control passes
- Move the dev36 integration harness into tests/live/tools; outputs go to
cwd / $TMDO_LIVE_OUT, site URL and path are env-configurable
- Verify: wp --path=<dev36> eval-file tests/live/run.php shadow_write
→ 1 passed, 3 xfail; unit 658 OK, integration 480 OK,
phpcs (phpcs.xml) 0, stan OK
- PR: PR-052
