A single-user, mobile-first PWA for tracking body recomposition — weight, body circumferences, progress photos, and daily nutrition adherence — with optional hardware auto-capture and zero third-party cloud in the data path. Built to deploy on Cloudflare.

• React 19 + Vite 6, installable PWA (vite-plugin-pwa, offline shell)
• Hono API on a single Cloudflare Worker (serves the SPA + /api/*)
• Cloudflare D1 (SQLite) + Drizzle ORM
• Cloudflare R2 for progress photos
• Auth via Cloudflare Access (the scale-ingest endpoint uses a service token)

• Weight — an Etekcity ESF-551 BLE scale read locally by a small Python listener that POSTs to /api/ingest/weight. No vendor app/cloud.
• Circumferences — a RENPHO RF-BMF01 BLE tape measure read in-browser via the Web Bluetooth API (Android/Chromium/Linux). No vendor app/cloud.

Body fat % (BIA) is captured when available but treated as a noisy, trend-only signal — weight (weekly average) and circumferences are the metrics that matter.

npm install
npm run dev              # http://localhost:5173
npm run build
npm run typecheck
npm run db:generate      # generate a D1 migration from src/db/schema.ts
npm run db:migrate:local # apply migrations to the local D1

The HTTP API is documented in-code: each route carries an @openapi JSDoc comment (in src/worker/index.ts), and the shared data models live as @openapi component comments next to the Drizzle tables (src/db/schema.ts). A build step assembles them into a single OpenAPI 3.1 document.

npm run openapi:gen      # comments -> src/worker/openapi.gen.json (also runs on prebuild)
npm run openapi:lint     # quobix vacuum, gated at a perfect 100/100 score

The generated spec is served by the Worker at /openapi.json (live). CI regenerates the spec, fails if the committed copy drifted from the comments, and holds the vacuum score at 100.

A terminal client lives in packages/cli and ships to npm as @skeptrune/telemetry-cli (plus standalone binaries on each GitHub Release). It authenticates with browser SSO through Cloudflare Access — no API key.
