pub const METRICS_SHM_PREFIX: &str = "/msb-met";Expand description
Prefix used when constructing the POSIX shared-memory object name for the
live metrics registry. Combined with a stable hash of GlobalConfig::home()
so concurrent MSB_HOME-isolated environments do not collide.
Kept short because macOS limits shm_open names to ~31 bytes including the
leading slash; the final form is <prefix>-<hex16>-v1 (28 bytes).
