The playwright WS-server path (camoufox.server.launch_server) is incompatible
with playwright >=1.45: camoufox 0.4.11's launchServer.js requires
playwright/driver/package/lib/browserServerImpl.js, which no longer exists in
any playwright 1.45-1.60 → tradein-browser crash-looped with MODULE_NOT_FOUND
('Server process terminated unexpectedly'). Verified by running the built image.
Pivot (no playwright protocol between containers):
- browser/server.py: aiohttp service holding a local AsyncCamoufox (headless,
os/locale/geoip/humanize, proxy from SCRAPER_PROXY_URL). POST /fetch {url} →
new_page/goto/content/close → {html}; GET /health. Page-recycle every N +
crash-recovery (relaunch + 1 retry), serialized via asyncio.Lock.
- browser/Dockerfile: +aiohttp (camoufox fetch-as-root/#908 block untouched).
- backend BrowserFetcher: playwright.connect → httpx POST to the browser service
(one retry on transport/HTTP error). All playwright imports dropped.
- config: browser_ws_endpoint → browser_http_endpoint (http://tradein-browser:3000).
Verified by a REAL local image build + run: image builds, container stays Up
(Restarts=0, no crash-loop), GET /health=200, POST /fetch launches camoufox and
drives Firefox (only NS_ERROR_UNKNOWN_HOST = no DNS egress in the local build env,
proving the full HTTP→camoufox→Firefox chain; real fetch validates on prod with
network+proxy). 7 unit tests + ruff clean.
Dormant: scraper_fetch_mode stays curl_cffi. Refs #905, #883, #884
