Prod debug (ssh, headless=True + mobileproxy): the camoufox fetch was returning
a 274KB generic avito shell with 0 listings — NOT a block/captcha (no
captcha/datadome/firewall markers, status 200, correct final_url). Avito hydrates
the SERP listings into the DOM client-side AFTER domcontentloaded; at the 2500ms
wait the page.content() snapshot still had only the generic shell. At 5-6s it's
the full SERP: 3.2MB, priceDetailed=50.
Fix: BROWSER_WAIT_MS default 2500→6000 (5s proven full + 1s margin), config.py
browser_wait_ms 2500→6000 to match. The whole camoufox+proxy migration works —
this was the last blocker. NOT headless detection (headless=True returns real
data); the abandoned xvfb/headless=virtual change is unnecessary.

Drive-by: browser/server.py was never linted (pre-commit ruff is scoped to
backend/), so #909 left an unused noqa + a 101-char line. Cleaned up while
editing this file for the proxy fix.
Prod smoke: tradein-browser fetched avito but got the ~400KB soft-block stub
(preloadedState present but priceDetailed=0, firewall=0) — because camoufox ran
with NO proxy (datacenter IP). Root cause: server.py read SCRAPER_PROXY_URL, but
the proxy in backend/.env.runtime is named AVITO_PROXY_URL (mobileproxy, #623) —
the same var curl_cffi-avito uses. So the var was empty in the browser container.
Fix: read AVITO_PROXY_URL first, SCRAPER_PROXY_URL as a generic fallback. One-line
env-name swap; the value is the working mobileproxy egress already on the host.
After deploy, re-run tradein-mvp/scripts/browser-smoke.sh — expect real data
(priceDetailed>0, ~1.4MB, firewall 0). IP rotation (AVITO_PROXY_ROTATE_URL) stays
backend-side and keeps working (same proxy endpoint, changing egress IP).

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
CI build-browser (and the deploy) went red on #907's browser image:
PermissionError: [Errno 13] Permission denied:
'/usr/local/lib/python3.12/site-packages/camoufox/GeoLite2-City.mmdb'
camoufox fetch with geoip=True downloads TWO things: the Firefox build (→
$HOME/.cache, correctly routed to /home/app via ENV HOME, the #899 fix) AND the
GeoLite2 mmdb, which it writes INTO the camoufox package dir in site-packages.
Since the browser image pip-installs camoufox as root, that dir is root-owned, so
running fetch as the app user can't write the mmdb → build fails.
Fix: run fetch as root (writes both the mmdb and — via ENV HOME — Firefox into
/home/app/.cache), then chown the Firefox cache to app. The mmdb stays root-owned
in site-packages but world-readable, which is all the runtime app user needs.
Verified by a real local image build (camoufox fetch now completes, image exports).
The deploy was gated off by the failed build-browser job (not partially applied),
so prod was never broken.
