## Integration fixes applied
**#1193:** Updated misleading comment — `OPENAI_API_KEY` does NOT authenticate the default Codex OAuth endpoint (that uses `chatgpt.com/backend-api/codex` and requires a separate OAuth flow). The comment now accurately states the known limitation. Also replaced a fragile 400-char source-scan test with an isolation-safe unit test. Note: OAuth-authenticated users already get detected via `hermes_cli.auth` — this fix only addresses the env-var fallback path.
## Test results
**2764 passed, 2 skipped** (macOS-only workspace tests). Browser QA: **21/21**. `/api/sessions` confirmed returning `server_time` and `server_tz` fields.
