fn wstore_workspace_exists(
store: &WaveStore,
workspace_id: &str,
) -> Result<bool, StoreError>Expand description
Existence check used by DeleteWorkspace to decide whether to
run the wcore delete path. Propagates StoreError so the caller
can surface real I/O / corruption failures instead of
misclassifying them as “not found” (codex P2 #615 carryover —
the prior bool return collapsed Err(_) into false, which
led to silent successes when SQLite was unhealthy: reducer would
delete its own copy and report success while the disk row was
never touched).
