UI-03 gate). Project ids cross the boundary as validated +//! [`ProjectSlug`]s — opaque values, never path fragments. Durable +//! writes go through [`save_bytes_atomic`] (unique temp file, fsync, +//! atomic rename, parent-directory sync where supported). Opening +//! returns [`OpenOutcome`], never a bare `Option` that conflates +//! "missing" with "corrupt". +//! +//!
