Final fix for scanner registration issue. Previous attempts
to add scanner import at module level were removed by the
pre-commit hook's ruff --fix auto-formatter.
Solution:
- Import scanners inside DiscoveryGraph.__init__() method
- Use the import (assign to _) so it's not "unused"
- Linter won't remove imports that are actually used
This ensures scanners always load when DiscoveryGraph is instantiated.
Verified: 8 scanners now properly registered

The scanner import needs # noqa: F401 to prevent linters from
removing it as "unused". The import is required for side effects
(triggering scanner registration).
Without this:
- Pre-commit hook removes the import
- Scanners don't register
- Discovery returns 0 candidates
Fix:
- Added # noqa: F401 comment to scanner import
- Linter will now preserve this import
- Verified 8 scanners properly registered

Critical bugfix: Scanner modules weren't being imported, causing
SCANNER_REGISTRY to remain empty and discovery to return 0 candidates.
Root Cause:
- Import line "from tradingagents.dataflows.discovery import scanners"
was accidentally removed during concurrent execution refactoring
- Without this import, scanner @register() decorators never execute
- Result: SCANNER_REGISTRY.get_all_scanners() returns empty list
Fix:
- Restored scanner import in discovery_graph.py line 6
- Scanners now properly register on module import
- Verified 8 scanners now registered and working
Impact:
- Before: 0 candidates, 0 recommendations
- After: 60-70 candidates, 15 recommendations (normal operation)

Tests verify:
- Single vendor stops after first success
- Multi-vendor stops after all primaries (even if they fail)
- Fallback vendors are not attempted when primaries are configured
- Tool-level config overrides category-level config
Tests use pytest with fixtures and mocked vendors, can run without API keys in CI/CD.
Run with: pytest tests/test_multi_vendor_routing.py -v
When multiple primary vendors are configured (e.g., 'reddit,alpha_vantage'),
the system now correctly stops after attempting all primary vendors instead
of continuing through all fallback vendors.
Changes:
- Track which primary vendors have been attempted in a list
- Add stopping condition when all primary vendors are attempted
- Preserve existing single-vendor behavior (stop after first success)
This prevents unnecessary API calls and ensures predictable behavior.
- Add .env.example file with API key placeholders
- Update README.md with .env file setup instructions
- Add dotenv loading in main.py for environment variables
