# This is NOT the Next.js you know This version has breaking changes — APIs, conventions, and file structure may all differ from your training data. Read the relevant guide in `node_modules/next/dist/docs/` before writing any code. Heed deprecation notices. # Repo Workflow - After finishing a requested change, stage the relevant files, create a commit, and push it to the remote repository. # Repository Boundary - Work only in `D:\works\kscompany\official-mail` for this project. - Do not read, edit, commit, push, or otherwise operate on `D:\works\kscompany\officialsite`. - If a task appears to require `officialsite`, stop and ask for explicit confirmation instead of touching that repository. # Local Dev Runbook - Do not assume plain `npm run dev` is enough for local verification. - For local browser testing, load environment variables from `.env.production` first, then override only these public URLs: - `NEXT_PUBLIC_APP_URL=http://127.0.0.1:3000` - `NEXT_PUBLIC_MAIL_APP_URL=http://127.0.0.1:3000` - Start the app with `npm run dev -- --hostname 127.0.0.1 --port 3000`. - Prefer `127.0.0.1` over `localhost` so local host/origin handling stays consistent with the app's auth and mail URL logic. - This local run mode is a local Next.js server connected to the external services configured in `.env.production`; it is not a fully isolated mock environment. - When the task is to verify login, mailbox access, or other real mail flows in the in-app browser, use the run mode above first instead of trying alternate ad hoc launch methods.
