* Switch browser engine from puppeteer-extra/stealth to CloakBrowser
- Replace puppeteer, puppeteer-extra, puppeteer-extra-plugin-stealth with
cloakbrowser + puppeteer-core; CloakBrowser applies 49 source-level C++
fingerprint patches that cannot be detected at the JS layer.
- Enable humanize:true in launchBrowser() for Bézier mouse curves, natural
keyboard timing, and realistic scroll physics.
- Remove manual userDataDir management and ARM64 executablePath override;
CloakBrowser ships its own binary for x86_64 and arm64.
- Proxy is now passed via CloakBrowser's native proxy option instead of
--proxy-server Chrome flag.
- Dockerfile: add fonts-noto-color-emoji + fonts-freefont-ttf so canvas
fingerprint hashes match real browsers (required for Kasada/Akamai);
replace npx puppeteer browsers install with node ensureBinary() call;
remove TARGETARCH ARG and ARM64 system-Chromium branch.
- Update test mock to reflect simplified browser object (no __fredy_* fields).

* Add --ignore-certificate-errors for CloakBrowser's custom Chromium
CloakBrowser ships its own Chromium binary with an independent CA bundle.
This flag prevents ERR_CERT_AUTHORITY_INVALID failures in environments with
SSL-inspecting proxies or non-standard root CAs (Docker CI, corporate networks).

* Harden CloakBrowser integration and fix kleinanzeigen detail test
- Remove all CDP overrides (applyBotPreventionToPage, applyLanguagePersistence,
applyPostNavigationHumanSignals) that created detectable inconsistencies on top
of CloakBrowser's C++ patches; pass locale to CloakBrowser launch instead
- Drop --lang arg (replaced by CloakBrowser locale flag)
- Extend immowelt puppeteerTimeout to 90 s to accommodate React SPA rendering
latency under CloakBrowser's humanise delays
- Fix kleinanzeigen detail test: serve the offline fixture for the search URL
so only individual detail pages are fetched live, avoiding rate limiting from
a second fresh session hitting the same search endpoint
https://claude.ai/code/session_01WXzA3orbwE2hdk723c6MgH
* Fix immowelt bot detection with two-phase navigation and fixture-backed detail test
Immowelt's CDN challenges cold browser sessions before React can render the
listing grid, causing the old waitForSelector approach to silently timeout.
- Add preNavigateUrl option to puppeteerExtractor: visits a warm-up page
first so the site sees an established session before the search URL
- Add waitForNetworkIdle option: a second idle-wait phase after domcontentloaded
that catches React's listing API round-trip (which fires long after the
initial HTML is parsed); errors are swallowed so partial DOM is still used
- Switch immowelt config to waitForSelector=null + networkidle warm-up so
page.content() is returned after the SPA has loaded its data
- Set immowelt preNavigateUrl to the homepage to warm the session
- In the detail enrichment test, spy on puppeteerExtractor to serve the
offline fixture for the search URL; only individual listing detail pages
are fetched live (they are far less aggressively protected)

* Ensure CloakBrowser binary is present before any live test runs
Add a Vitest globalSetup that calls ensureBinary() once in the main process
before workers start. Without this, running yarn test on a fresh checkout
(or after the binary cache is cleared) immediately fails every browser-based
test with "Failed to launch the browser process" before any useful output
appears. The setup is a no-op in offline mode and when the binary is already
cached.
https://claude.ai/code/session_01WXzA3orbwE2hdk723c6MgH
* Ensure CloakBrowser binary at startup for non-Docker installs
Direct runs (yarn start:backend) on a fresh checkout have no binary and
only crash when the first scraping job fires. Calling ensureBinary() at
startup downloads it on first run and is instant when already cached.
In Docker it stays a no-op since the binary is pre-baked during docker build.

* Fix --no-zygote comment: ICU crash was corrupted .4 binary, not fd issue
The "Invalid file descriptor to ICU data received" crash seen in Sparkasse
tests was caused by a partially-extracted CloakBrowser .4 binary that
contained only the chrome executable but was missing icudtl.dat and other
resource files. The ensureBinary() function returned this incomplete
installation because latest_version_linux-x64 pointed to .4.
The --no-zygote flag is kept as a safeguard for container environments
with limited kernel namespaces, but the comment now accurately describes
its purpose rather than attributing it to a non-existent fd inheritance issue.
https://claude.ai/code/session_01WXzA3orbwE2hdk723c6MgH
* Add ensureValidBinary() to detect and auto-heal corrupt CloakBrowser installs
CloakBrowser's ensureBinary() only checks that the chrome executable exists,
not that required resource files (icudtl.dat, resources.pak) are present.
A partial extraction — e.g. an interrupted update — can leave a directory
that passes ensureBinary()'s check but causes Chrome to crash immediately
with "Invalid file descriptor to ICU data received".
ensureValidBinary() wraps ensureBinary() with a completeness check:
- If the required resource files are missing it removes the corrupt directory
and all latest_version* markers, then calls ensureBinary() again so it
falls back to (or re-downloads) a complete build.
- It pins the validated path via CLOAKBROWSER_BINARY_PATH so CloakBrowser's
own internal ensureBinary() call inside launch() always uses the same,
verified binary.
Used in index.js (app startup) and test/globalSetup.js (before live tests).

* Fix sparkasse detail test: serve search URL from fixture to avoid rate-limiting
The second sparkasse test launched a fresh browser against the live search
endpoint right after the first test already did, leaving the IP in a suspicious
state that caused bot detection or rate-limiting to return empty results.
When getListings() returns nothing, execute() resolves to undefined and
expect(listings).toBeInstanceOf(Array) fails.
Apply the same hybrid fixture approach used by kleinanzeigen and immowelt:
intercept puppeteerExtractor calls whose pathname matches the search URL and
return the offline fixture, while letting individual detail page requests go
live (they are less aggressively rate-limited than the search endpoint).
https://claude.ai/code/session_01WXzA3orbwE2hdk723c6MgH
* Fix sparkasse detail test: shared browser, direct fetchDetails call
Remove the fixture-backed spy — live tests must hit the real server.
Root problem: two cold browser sessions hitting sparkasse in quick succession
triggered bot detection, causing the second search request to return empty
results and execute() to resolve undefined.
Fix:
- One browser launched in beforeAll and reused across both tests, so both
the search and detail requests come from the same warm session.
- The detail test calls provider.config.fetchDetails() directly on the
listings returned by the first test instead of re-running the full pipeline.
This avoids a redundant second scrape of the search page while still
exercising the live detail endpoint.
https://claude.ai/code/session_01WXzA3orbwE2hdk723c6MgH
* Eliminate fixture spies and double live requests in all provider detail tests
All five provider tests with a 'with provider_details enabled' describe block
were either (a) intercepting the search URL with an offline fixture to avoid
hitting the live server twice, or (b) re-running the full execute() pipeline
with a fresh browser, which triggered rate-limiting / bot detection on the
second cold request.
Pattern applied to all five:
- immowelt, kleinanzeigen, wgGesucht, immobilienDe: launch one browser in
beforeAll/afterAll, pass it to the first test's Fredy constructor, and call
provider.config.fetchDetails() directly in the second test using the listings
and browser already in hand. One warm session, two live endpoints tested.
- immoscout: API-based (no browser), so no browser sharing needed. Second test
calls provider.config.fetchDetails() directly on liveListings[0] from the
first test instead of re-querying the search API.
Removed: all readFixture spies, getKnownListingHashesForJobAndProvider mocks,
and the puppeteerExtractorMod imports that were only needed for the spy.

* Fix ensureValidBinary for macOS: platform-aware completeness check
On macOS the CloakBrowser binary lives at:
~/.cloakbrowser/chromium-X.Y.Z/Chromium.app/Contents/MacOS/Chromium
path.dirname() gave Contents/MacOS/ — but icudtl.dat and resources.pak
are inside Contents/Frameworks/…, not next to the binary. So the old
code incorrectly flagged every macOS installation as corrupt, deleted only
the MacOS/ subdirectory (not the full versioned dir), then failed again.
Fixes:
- isBinaryComplete: on macOS check for Info.plist and Frameworks/ inside
Chromium.app/Contents/ instead of looking for Linux resource files next
to the binary. On Linux/Windows the existing check is unchanged.
- getVersionedDir: resolves the full chromium-X.Y.Z/ directory regardless
of platform (4 levels up on macOS, 1 on Linux/Windows) so
removeCorruptInstallation always deletes the entire versioned tree.
- missingDescription: reports the correct missing items per platform.
