Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: ๐ก Moderate ยท up to The UTF-8 comparison fix prevents malformed API keys from causing server errors, but runtime verification still reads keys from the environment instead of the required credential registry. This can cause inconsistent authentication across deployments, so the PR is not merge-ready until the credential source is corrected or explicitly accepted. Possibly related PRs

๐ API keys still sourced from env var
AGENTS.md flags CODEC_CARVER_API_KEYS env reads in get_configured_api_keys as a deviation to migrate to a credential registry. This PR edits the auth middleware but leaves that env read in place. Pre-existing, not introduced here.

๐ Info: compare_digest encoding fix is correct
Encoding both operands to UTF-8 bytes eliminates the non-ASCII TypeError while leaving ASCII-key comparison unchanged. Starlette decodes headers as latin-1, so a non-ASCII header is re-encoded to different bytes here, but that only yields a mismatch, never a false match.
