Testing that survives everything. Sentinel Loop persists its full state to disk after every significant action, enabling multi-day testing across unlimited sessions. Survives context limits, timeouts, and crashes. The state machine cycles through INIT, RECONNAISSANCE, TESTING, FIXING, VERIFYING, and COMPLETE phases, always resumable from the exact point of interruption.
