Adds three pure-logic evaluators + scenarios + unit tests covering the project's failure-mode robustness ladder (AC-3.1, AC-3.4, AC-3.5, AC-NEW-8): * outlier_tolerance_evaluator (AZ-424 / FT-N-01): per-event 50 m drift bound + 3-frame covariance-monotonic window over the AZ-408 outlier injector's medium-density manifest. * outage_request_evaluator (AZ-425 / FT-N-03): detects 3+ consecutive missing-frame windows; validates OPERATOR_RELOC_REQUEST STATUSTEXT arrives at 2 s ±500 ms, dead_reckoned label during outage, and no FC EKF divergence. * blackout_spoof_evaluator (AZ-426 / FT-N-04): eight-AC ladder across the 5 s / 15 s / 35 s sub-windows — switch latency, spoof rejection, monotonic covariance, honest horiz_accuracy, STATUSTEXT 1-2 Hz, 35 s escalation thresholds, and recovery gate. Each scenario is skip-gated on the AZ-441 / AZ-407 / AZ-416 replay / SITL / mavproxy helpers; unit tests (14 + 18 + 29 = 61) cover the AC logic today. Full e2e unit-test suite: 527 passed (+67).
