 4. **Commit + tag** — a commit is created for each change, tagged with the version (e.g. `v0.1.0`).

+1. **Compose instance is the app under test** — e2e always runs against the docker-compose build behind Traefik (`https://flight.dev.kkhost.pl`), never a local `next dev` on :3000 (dev builds don't render for non-loopback clients, and a second instance splits state).
+2. **Update before testing** — deploy current code first: `docker compose up -d --build`.
+3. **Remote browsers** — tests run through the shared Playwright server at `192.168.1.4:3000` (Docker image tag must match this repo's @playwright/test version); plain `npx playwright test` handles deploy + readiness + remote connect (see `playwright.config.ts`).

 # Changelog
 
+## v0.2.5 — 2026-09-16 21:22
+- `AGENTS.md`: new "E2E tests (mandatory)" section codifies the e2e workflow — the compose instance behind Traefik (`https://flight.dev.kkhost.pl`) is always the app under test, never a local `next dev` on :3000; deploy current code first with `docker compose up -d --build`; browsers run through the shared remote Playwright server at `192.168.1.4:3000`, and plain `npx playwright test` handles deploy + readiness + remote connect
+- `playwright.config.ts`: dropped the `E2E_LOCAL=1` local-dev path accordingly — no more local :3000 dev instance for e2e; the default (and only) mode is browsers on the shared remote Playwright server against the prod build behind Traefik, with `webServer` running `docker compose up -d --build`; `E2E_REMOTE=1` and explicit `PW_TEST_CONNECT_WS_ENDPOINT`/`E2E_BASE_URL` overrides are unchanged
+
 ## v0.2.4 — 2026-09-16 21:06
 - `playwright.config.ts`: default e2e mode now targets the prod build behind Traefik (`https://flight.dev.kkhost.pl`) — `baseURL` defaults to that URL and `webServer` runs `docker compose up -d --build` (300 s timeout) instead of `npm run dev`, because `next dev` does not render for non-loopback clients: Turbopack's HMR WebSocket fails from the remote browsers, so the page loads blank
 - `E2E_LOCAL=1` keeps the local iteration path (browsers on this box, `webServer` auto-starts `npm run dev`, baseURL `localhost:3000`) as a fallback when the proxy or compose stack is down; `E2E_REMOTE=1` and explicit `PW_TEST_CONNECT_WS_ENDPOINT`/`E2E_BASE_URL` overrides are unchanged
