A local five-error speed screen retains 270 shower-assigned GMN events under strict 2025 trajectory cuts

We test a local solar-escape speed screen in frozen Global Meteor Network annual data. In a 2025 quality sample, 2,050 shower-assigned meteors lie above local escape speed by more than five quoted speed errors. Of these, 270 pass added cuts for stations, fit error, track duration, geometry, and field coverage. A 2024 sample gives 1,736 and 232. An initial-speed cut below 50 km/s still leaves 90 assigned selections in 2025. All five-error cases exceed the boundary by more than 2 m/s. A separate orbital check agrees with the date boundary within 0.928 m/s. Shower labels use the same measurements and can be wrong. The counts do not calibrate the errors or confirm interstellar origin. The bundle gives control data, code, source hashes, figures, error-floor tests, and offline reproduction steps. No independent instrument trajectory was processed.
