Sites with missing or short APP_SECRET now keep booting after a patch upgrade while WordPress and Symfony application caches use request memory. Strong secrets enable signed persistence across all configured application backends; unsigned or modified existing values are discarded before deserialization.
SYMPRESS_PROJECT_DIR supplies a literal stable cache identity across numbered releases, while code/config discovery stays on the actual release. Custom object classes can be explicitly allowlisted.
Validation: full QA, 66 tests/334 assertions; complete live Redis/Memcached/APCu suite, 66/387 with zero skips. Real containers using the prior Kernel 1.1.3 cover missing/short/strong keys, cache.app and named pools, persistence boundaries and tampered payloads.
