# Resilience Test Scenarios

## RT-DSF-01: Dataset formation with empty data directory
- **Input**: Empty data images dir
- **Action**: Run `form_dataset()`
- **Expected**: Creates empty train/valid/test directories; no crash
- **Traces**: Restriction: Edge case handling

## RT-ENC-01: Decrypt with corrupted ciphertext
- **Input**: Randomly modified ciphertext bytes
- **Action**: `Security.decrypt_to(corrupted_bytes, key)`
- **Expected**: Either raises exception or returns garbage bytes (not original)
- **Traces**: AC: Encryption integrity

## RT-AQM-01: Malformed msgpack message
- **Input**: Random bytes that aren't valid msgpack
- **Action**: Pass to message handler
- **Expected**: Exception caught; handler doesn't crash
- **Traces**: AC: Error handling for malformed messages
