"""Integration tests for GitHub signal extraction.

Tests that the GitHub extractor:
1. Connects to the API with valid credentials
2. Fetches repository activity (commits, PRs, issues)
3. Extracts signals with proper types
4. Tracks freshness since last sync

Run with:
    pytest tests/integration/test_github_channel.py -v -m integration

Requires:
    GITHUB_TOKEN environment variable
