What it does

Airframe structural fatigue analysis. Miner's rule accumulation with R(t)-weighted load spectra, crack growth rate (Paris law), remaining flight cycles.

Integrate

1. Domain solver — compose with KO42 + two additional operators from the matching family for pulse-coherent results.
2. Digital twin — pipe sensor data into this protocol every Zeqond to keep the model phase-locked with the system.
3. Alert threshold — flag results whose error_pct exceeds 0.1% as out-of-spec events for the operations layer.

Seeds

• Near — wrap /api/aviation/fatigue in a language SDK so builders can call it in three lines.
• Medium — publish a reference integration demonstrating ZeqAirframeFatigue alongside a real workload, with pulse-aligned metrics.
• Far — propose ZeqAirframeFatigue as an open reference standard so other runtimes can implement it verbatim against the Zeq paper.
