	audio_artifacts.hpp
	JSON metrics artifacts for failing render scenarios (harness PR 1B).
	audio_assertions.hpp
	Reusable signal assertions over rendered buffers (harness PR 1A).
	audio_doctor_artifacts.hpp
	JSON curve artifacts for the offline Audio Doctor.
	audio_metrics.hpp
	Deterministic offline signal metrics for rendered audio buffers.
	audio_spectrum.hpp
	Buffer-level offline spectrum analyzers: magnitude/frequency response and harmonic distortion (THD / THD+N) over already-rendered audio buffers.
	latency_evidence.hpp
	Measured-versus-reported latency: the evidence schema and its pure evaluators.
	modal_extraction.hpp
	Offline modal analysis of a rendered impulse response or note: recover the resonant modes (frequency, T60, amplitude), track partials and measure inharmonicity, and resolve a single quasi-sinusoidal note's f0(t), decay rate sigma(t) and Q(t) cycle by cycle.
	pitch_track.hpp
	Accurate fundamental-frequency estimation for harmonically-dense, bandlimited oscillator output, plus an f0(t) trajectory extractor over a render.
