Close CI Cleaner failure issue - transient infrastructure timing issue

[Copilot]

CI Cleaner workflow run #355 failed on 2026-01-11 when MCP server connectivity checks timed out during gateway initialization. Investigation shows this was a transient infrastructure issue that self-resolved without code changes.

Analysis

Failure pattern:

• Run [Custom Engine Test] Test Issue Created by Custom Engine #354: Failed ❌
• Run [Custom Engine Test] Test Issue Created by Custom Engine #355: Failed ❌ (reported issue)
• Run [Custom Engine Test] Test Pull Request - Custom Engine Safe Output #356: Success ✅ (12 hours later, no code changes)
• Runs [Custom Engine Test] Test Issue Created by Custom Engine #357-363: All successful ✅

Root cause: Both github and safeoutputs MCP servers failed to respond to ping requests despite existing retry logic (3 attempts × progressive timeouts 10s/20s/30s). Gateway health check passed, but individual server initialization timing exceeded retry windows.

Infrastructure indicators:

• No code changes between failures and recovery
• Immediate recovery after brief period
• Consistent success pattern since recovery
• Timing suggests container registry/network latency

Existing resilience (sufficient)

Gateway startup already implements comprehensive retry mechanisms:

• Health check: 120 retries × 1s = 120s timeout
• Server pings: 3 retries with progressive delays (2s, 4s) and timeouts (10s, 20s, 30s)

Conclusion

No code changes required. Transient infrastructure issue resolved itself. Closing issue as resolved.
