Engineering scope and evidence boundary

This topic groups the release-backed flight-control records that OpenFly can verify from their official repository or project source. The page is an entry point for comparing the role of a flight stack, a flight-controller firmware project, and a command-line control tool without treating their different resource types as interchangeable. It deliberately keeps scope at the software and project-record level: aircraft hardware, measured flight performance, and compatibility claims remain outside the page unless a SourceRef records them. Resource cards expose the current verification status, maintenance signal, source tier, and retrieval date so a reader can move from the topic explanation to the underlying evidence.

Topic membership is an editorial index, not a compatibility or performance claim. Verify each resource through its SourceRef, retrieval date, and verification status.
