Status: OUT
The testing methodology covers neither single-node crash failures nor distributed asynchronous failures: crash recovery paths are systematically untested (no torn-write tests, no compaction crash tests), and distributed protocols are validated only under synchronous deterministic simulation with no real network I/O — the entire failure surface area from storage crashes to network partitions is invisible to the test suite.
Two conclusions at different depths both identify testing blind spots — one for storage-layer crashes (depth-1), one for protocol-layer async behavior (depth-2) — spanning the full stack
