FaultClassification
Ready-to-run robot software for hobby robotics.
Declared in src/libs/libfixo/fixo/runtime/ConnectionFault.hpp.
Detailed description
Classify a probe outcome into a (category, detail) pair. The detail string is the coalescing key's tail — for A1 it's the port name; for B1 it's just "(empty)" because every B1 collapses onto the same key by design.
Deterministic. No heuristics that change under load.
