Eight thousand four hundred and eighty bytes — not 8 MB, not 8 GB. It fits on the microcontroller already inside the machine.
Learns normal behavior in 1,700 samples — under two seconds at kilohertz rates — then locks. No labels, no tuning.
Zero dynamic allocation after initialization. Safety-critical firmware forbids the heap; Flynn meets that rule by construction.
Flynn ships as a compact binary, compiled for your hardware. Deterministic and verifiable against published test vectors; full source available to certifying authorities under NDA.
Zero false positives across 120 hours of soak testing, with a 95%-confidence ceiling of 0.025 per hour.
Deterministic across runs and silicon. Replayable. Auditable. Eligible for safety-certified voting architectures.
† Samples required for complete enrollment will vary by equipment type, state, and operational envelope.
The CWRU bearing dataset spans 27 fault pairs across inner-race, ball, and outer-race faults at three severity levels. The recommended operating point produces the deployed numbers below, with no oracle threshold and no per-fault tuning.
An industry-standard run-to-failure dataset spans more than 30 days of continuous vibration from four bearings, two of which failed and two of which survived. Flynn ran on all eight accelerometer channels simultaneously — zero configuration changes between them.
336 hours of ambient time-series covering temperature, environmental, and process-control signals — slow-changing data with strong day-night cycles. Flynn maintains a false-positive rate that fits the cadence of normal operator review.
10,000 instances across 12 features of electrical-grid stability data — a signal domain that shares nothing with rotating-machinery vibration. Same source, same flags, no per-domain configuration.
The false-alarm rate is the first thing operators ask about. Across 120 simulated hours of synthetic vibration — 5 random seeds × 24 hours each — Flynn produced zero false positives, with a 95%-confidence ceiling of 0.025 per hour. On bearing normal-operation traces, zero across 1.2 million samples.
Zero false positives on bearing data. Operationally low on diurnal. The numbers operators actually care about.
Flynn's empirical claims are reproducible from committed benchmarks and committed source code. Artifacts and reproduction instructions are available to evaluation licensees.
