## Why SQLite page reclamation on NFS creates I/O load and contention. ## What changed Detect whether `sqlite_home` is on NFS on Linux and skip reclamation before opening a maintenance connection. Cache successful filesystem probes across `SqliteConfig` clones while allowing failed probes to retry. ## Testing Add tests for shared probe caching and recovery after a missing directory is created. Update reclamation coverage to expect no reclaimed pages or file shrinkage on NFS. GitOrigin-RevId: 4f627cabc6ad712171654c3f8b8659d2f632bbba
