- On a cache miss the filter fell back to get_option(): with the values now written to the cache, the option is absent, so WordPress added its name to `notoptions` for good (dev36: +1,000 entries for 1,000 posts, one array loaded on every miss); a hit kept the old row in the options cache group with no expiry, which slowed the selective Redis flush (8.9 s, BUSY). The cache is now the only store for reads and deletes; old rows wait for cleanup-hp-transients --options. Without an object cache nothing changes.
- Verify: HivepressTransientFilterTest (2 RED before); dev36 notoptions 210 → 210 over 1,000 posts (was 128 → 1,128)
