Tepna is a set of single-signal analyzers for the physiology sensors people actually own — a ring oximeter, a chest strap, an armband, a CGM, a CPAP machine — plus one capture box that records them all night on one clock. Each analyzer reads one raw signal, derives its metrics, and reports over a shared bus (Ganglior) so a fusion layer (the Integrator) can read across signals. Every number carries an evidence grade. The suite uploads nothing, ever: a headless gate boots every shipped surface and fails the build if anything reaches for the network.
What it finds that holds ships as a graded metric. The project publishes what fails too — Dead Ends is the citable map of the walls. The long-form why is…
