adapter.py:setup() now emits a logger.warning() if CLAUDE_CODE_OAUTH_TOKEN
is absent, so operators see the problem immediately instead of getting a silent
AuthenticationError on the first LLM call. known-issues.md updated to mark
KI-001 as resolved.
Recovered from prior work. Previously pushed commit 03c6929
was lost during reset-to-origin/main divergence resolution.
