3. Recommended Remediation & Verification Next Steps

1. Pre-merge CI Enforcement: Maintain ./gradlew lint and ./gradlew test gating to prevent regressions.
2. Buffer & Resource Lifecycle: Ensure every off-heap DirectByteBuffer and UsbDeviceConnection is enclosed in defensive cleanup or use {} / close() wrappers.
3. Integer Arithmetic Bounds: Verify 64-bit casting (toLong()) prior to any multiplication involving sectors or block sizes to prevent 32-bit integer overflows.
4. SCSI Check Condition Propagation: Maintain strict Request Sense queries upon CHECK CONDITION to preserve device diagnostic integrity.
