- With a persistent object cache (wp_using_ext_object_cache(), Redis on the HivePress sites) the transient filter stores HivePress's per-post transient pairs in the tmdo_hp_transient cache group instead of wp_options, where they piled up (1.15 M rows on dev36). Reads fall back to wp_options for values written before; deletes clear both. Without an object cache nothing changes.
- Verify: HivepressTransientFilterTest object-cache cases (RED before); dev36 with Redis: update/get/delete_post_meta on an HP transient key leaves 0 rows in wp_options and postmeta.
