Mic pitch → folded to the global scale → played as notes, or (when ⚡
GODSPEED is on) latched into the arp one note at a time. The mic lives
in its OWN throwaway AudioContext — it is analysed, never routed into
the music graph (zero feedback), and nothing leaves the page. A pure
autocorrelation detector psalmDetect(buf,sr)→{freq,clarity,rms} (80–1000
Hz, parabolic interpolation) and a pure note state-machine psalmStep()
(2 stable frames to fire, legato on change, 150ms gate close + re-attack,
velocity from RMS) — both unit-tested headlessly. A 🕊 chip shows the
sung note and brightens on voice; a ctxItem toggles it; mic denial
tickers "the instrument cannot hear you".
Verified: detector 220/440/554Hz within 0.09% (silence & noise gated),
fold lands in-scale, the state machine single-fires / legatos /
re-attacks / scales velocity, the ctxItem + mic-denial path work live,
zero console errors.
