Context

BrowserTrace now documents the Browser Use local HTML upload navigation failure in the Browser Use guide and the high-level failure-patterns page:

• Guide anchor: https://aaronlab.github.io/browsertrace/browser-use-debugging.html#debug-local-html-upload-navigation
• Failure-patterns anchor: https://aaronlab.github.io/browsertrace/browser-agent-failure-patterns.html#debug-local-html-upload-navigation
• Related upstream case: Bug: uploading an html file causes the agent to try to navigate to a web page browser-use/browser-use#4794

The README currently lists several concrete failure patterns, but it does not mention this local HTML upload navigation case yet.

Scope

Please make a tiny docs-only update:

1. Update the README failure-patterns summary near the top to include Browser Use local HTML upload navigation mistakes.
2. Keep the wording concise; this should be a short mention, not a new long section.
3. Link to the existing failure-patterns page or Browser Use guide if the surrounding README wording already uses links.
4. Add focused metadata coverage in tests/test_metadata.py if needed so this README mention stays present.

Out of scope

• No Browser Use adapter code changes.
• No broad README rewrite.
• No private prompt, credential, file-content, screenshot, or page-content examples.
• No stars/upvotes/reposts requests.

Verification

Run:

uv run --python 3.11 --extra dev pytest tests/test_metadata.py -q
git diff --check
