- sweep() skips meta rows already in wpdo_archive (NOT EXISTS on
original_meta_id): it copied the same trashed meta again every day and
wpdo_archive has no unique key (dev20: 300 rows for 150 meta rows)
- TMDO_Zone_Archive::remove_duplicates() keeps the first copy per
original_meta_id (rows without one are left alone); install() runs it,
so `wp tmdo install` cleans existing sites
- wpdo_archive gets KEY idx_original_meta for the lookup (new installs;
existing sites via `wp tmdo install`). SCHEMA_VERSION is not bumped, so
no web request runs dbDelta
- Verify: ZoneArchiveIntegrationTest (2 new); dev20 read-only check: 150 of
300 rows would be removed; unit 709, integration 608, phpcs 0, stan OK
- PR: PR-136 (manual F-6)
