Recommended action: Check that LANGSMITH_API_KEY and LANGSMITH_ENDPOINT refer to the same deployment/region, enable logging for the langsmith logger to see warnings, and call Client().list_projects(limit=1) or similar once to fail loudly on auth.
Option: Verify key/endpoint pairing with a synchronous call [evidence: documented_workaround]
Applies when: Missing traces
Steps:
1. export LANGSMITH_API_KEY=... LANGSMITH_ENDPOINT=<matching region URL>
2. python -c "from langsmith import Client; print(list(Client().list_projects(limit=1)))"
Expected: Auth errors surface immediately
