Syntax layer: classify sign tuples into named temporal motifs. Syntax layer: classify sign tuples into named temporal motifs.
The syntax layer sits between the sign tuple and the grammar state.
It maps σ(k) = (‖r‖, ṙ, r̈) onto a named MotifClass, which
the heuristics bank then looks up to retrieve operator-facing
semantic dispositions and provenance.
§RF Motif Classes (paper §V-F)
| Class | Signature | RF Context |
|---|---|---|
| PreFailureSlowDrift | norm in [0.3ρ,ρ], ṙ>0 sustained | PA thermal drift, LO aging |
| TransientExcursion | norm > ρ for 1–2 obs, rapid recovery | Single-sample noise spike |
| RecurrentBoundaryApproach | periodic boundary entries | Cyclic interference |
| AbruptOnset | r̈ >> 0 with large norm jump | Jamming onset, HW fault |
| SpectralMaskApproach | norm drifting toward 1.0 (normalized mask) | TX power creep |
| PhaseNoiseExcursion | oscillatory ṙ with growing | ṙ |
| FreqHopTransition | abrupt slew + recovery to new baseline | FHSS waveform boundary |
| Unknown | no pattern matches | Endoductive: return σ(k) for operator |
