# RBFL Reference-Gauge Multi-Channel Phase Detector Test

Status: detection-stage run only. The locked RBFL law was not changed.

Main law remains: g_RBFL = g_b + A_b sqrt(a_phi g_b).

This run locks NGC7331 as the zero-phase/reference gauge and uses observables to decode phase state.
The detector uses phase-tuner gauge features, baryonic summary features, central-node/rotation proxies,
and post-test residual/lensing-event observables. These are treated as detector channels, not law terms.

Key caution: the multichannel detector is a phase decoder trained/calibrated on the provided data. It
should not be described as a blind forward validation. It is a detection-stage tolerance test.
