ZeqPLNB — Phase-Locked Neural Bridge

Project an observer-supplied 1-D signal (EEG band, breath cycle, finger-tap, etc.) onto the 1.287 Hz HulyaPulse carrier and return coherence γ, observer phase φ_obs, the PLNB1 amplitude, and a recommended awareness-family operator chain. v1 returns the recommendation only — execution is left to a follow-up /api/zeq/compute call.

Parameters

Name	Type	Required	Description
signal	array	Yes	Real-valued samples (16–4096) of the observer signal.
sampleRateHz	number	Yes	Sample rate of signal in Hz; must satisfy Nyquist for HulyaPulse (≥ 2.574 Hz).
intent	string	No	Opaque caller-supplied intent label, max 256 chars.

Returns

{ zeqondTick, phase, coherence: { gamma, inPhase, quadrature, phaseObsRad }, plnb1, recommendation: { operators, rationale }, precisionBound, integrityTag }
