- cooler.SiteCachePurger moved from the Journal plugin: loopback-only http,
32-character token, 2 s detached request, no token in logs or errors
- NewSiteCachePurgerFor names caller keys (for plugin alias keys)
- PurgeSiteCacheAfterCommit through lagoon.AfterCommit, one POST per save
- SiteCacheFromApp for hooks outside serve; Install publishes the purger
unless a plugin already did, and fails boot on an invalid config
- caching docs section, cooler README, configuration row
- Cache: Get, Set, Has, Forget, Remember (degrades on cache errors), Increment, Flush
with per-entry TTLs under <prefix>cache:
- memory driver on otter v2.3.0 bounded by cache.memory.max_entries; Redis driver
with SET PX, INCRBY and a Flush limited to SCAN MATCH <prefix>cache:* plus UNLINK
- Install publishes the Cache (sharing one Redis client with the rate limiter);
FromApp serves jobs and commands without a dial
- new docs/services/caching.md, configuration rows, cooler README
