What it is
Log bedtime and wake time — duration computed automatically. Sleep log (HPT-aware notes, not a medical device) is a core component of the P31 Labs sovereign cognitive infrastructure stack — built to run offline, deployed to the edge, and designed without dark patterns.
Chart.js annotated charts with a goal-band plugin. Sleep entries keyed by ISO date in localStorage. Duration and efficiency calculations done client-side. Wellness logging only — not FDA-regulated monitoring. Short p31ca.org URL 302 → workers.dev (probe: worker-spa-sleep-tracker).
