- Detached long-running jobs. Jobs survive client or network loss and can be re-attached via run ID.
- Cross-platform binary. Single dependency-free executable works on Linux, macOS and Windows.
- Local crash-safe state. Connection, vault and job state are written atomically to survive crashes.
- Integrated diagnostics. Commands like corv test and corv doctor provide structured connection health checks.
