# Deterministic crash-injection points. Compiled out entirely in release; see

# Journal-level drive API (`drive.rs`) used by the crash driver and the
# P1-micro benchmark before `StoreEngine::submit` exists. Test/bench seam only;
# never enabled in a release binary. See scope 2.1.

# Gates construction of `ValidatedTransaction`. Enabled only by validated
# ingest (`levcs-instance`), this crate's own recovery path, and the Phase 2
# migrator. Deliberately NOT reachable from `&StoreEngine`; see scope 2.2.
