ContainerCacheGuard v0.2.0-rc.4
Pre-release
ContainerCacheGuard v0.2.0-rc.4 is an experimental build for PostgreSQL 14 cache-pressure validation.
Changes: safely discover mode-0700 PostgreSQL relation files in explicit paths mode; speed up metadata traversal using a parent directory FD; delay the next large-tree sweep until after the prior sweep completes.
Verification: Linux/amd64 unit tests passed on the authorized AlmaLinux 9 test host. One real mode-0700 PG14 backup file was indexed in observe mode. The amd64 executable is a statically linked ELF. Arm64 was cross-compiled but has not been run on arm64 hardware.
Not yet established: full million-file coverage with this build, cache residency reduction under an active full backup, business latency impact, or Kubernetes eviction prevention. Do not treat this prerelease as production acceptance.
