Comments, docstrings and a few strings cited plan numbers ("plan 29
#9", "plan 86 §B2") from a git-ignored folder, so they pointed at
nothing; one reached users in a bottleneck hint. Code and frontend
strings are unchanged apart from those citations (checked by AST and
token comparison). A vhost still carrying the old asset comment reads
as undrifted, and a guard test keeps new citations out.
One TTL-memoization shape (Redis-backed where configured, in-memory
otherwise, None results never cached, .invalidate() per key).
install_profile_service capability probe and resource_tier_service tier
probe drop their hand-rolled module-level timestamp dicts. Ratchet with
a documented allowlist for caches whose semantics genuinely differ
(lock-guarded non-JSON snapshot, cache-forever catalog, the F1
remote-index family).

Phase 36: Redis caching with in-memory fallback, cache decorator for
functions, background job queue with worker pool, job status tracking,
cache stats/flush endpoints, and job cleanup.
