) -> SenseOutcome

The Phase-4 pipeline. Microphone PCM samples → (consent gate) → forward DSP → the ∫Ψ > τ → Fact bridge → a discrete Fact NQuin, or a refusal.

Order is deliberate: the consent gate runs first — if agent has no Active consent to capture environment, the function returns SenseOutcome::Refused and the signal is never turned into anything. When consented, the integrated time-domain energy is thresholded by the inherited bridge; on a crossing, the dominant tonal frequency (forward DFT) is attached to a discrete fact. Raw samples never leave this call.
