Versioned per-instance, content-addressed for integrity, with provenance chain back to source samples. Reuse set served by this single primitive: - DAC bit-accuracy + THD curves (per-DAC-serial) - Amplifier FRF + THD-vs-power curves (per-amp-serial) - Speaker FRF (per-driver-build, especially DIY where each build differs) - Microphone calibration curves (per-mic-serial) - Display gamma + gamut curves (per-display-serial) - Camera response curves (per-sensor-serial) - Haptic motor force curves - Hydrophone pressure response
