I wrote 731 comment lines on this branch against 4,530 lines of code — 14%, where the rest of the repo runs at 1.8%. CLAUDE.md asks for code that reads like its surroundings, and this did not. Removed by genre rather than by taste: - restating the code, e.g. "JS getUTCDay() numbering: Sunday = 0" above the map that literally shows it, and a docblock on startOfWeek explaining that it returns the start of the week; - narrating history — "this used to rebuild the whole map", "left the bar recording forever" — which the commit message and git blame already carry; - saying the same thing in several places: the "cannot record is not a denied microphone" reason appeared three times in one file, and the "aborting stops a per-minute metered call" reason across three files. Each now lives once, where the behaviour it explains lives; - defending decisions nobody would question, like why toLatinDigits is its own module; - over-explaining defensive branches, three separate comments to distinguish null from missing-kind from unrecognised-kind. What stays is what the code cannot say: the patient-right convention in toFdi, whose failure mode is a valid code for the wrong tooth; the "this"-vs-"next" week anchoring; StrictMode re-arming mountedRef; Safari accepting no mimeType hint; and the invariants whose violation already cost a bug — the body parser's middleware ordering and the dispatch panel's auto-fill rules. Comments only. The diff contains no non-comment line. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Dyolink — Frontend (Next.js)

Environment
Create
.env.localin this folder (not committed to git) with the public URLs your browser will use:NEXT_PUBLIC_APP_URL=http://localhost:3001 NEXT_PUBLIC_API_URL=http://localhost:3000/api NEXT_PUBLIC_APP_NAME=Dyolink- Adjust
NEXT_PUBLIC_API_URLif the Nest API runs on another host/port. - These values are baked in at build time for production images; for local dev, restart
npm run devafter changing them.
- Adjust
Run (development)
npm run dev
Open http://localhost:3001 (dev server uses port 3001 so it does not clash with the API on 3000).
Ensure the backend is running and NEXT_PUBLIC_API_URL matches its base URL (including /api if your API is mounted there).
After pulling latest main
git pull
npm install
