Investigation: Test Dispatcher Workflow failure (transient service issue)

[Copilot]

Investigation Only - No Code Changes Required

Run 21756317190 failed due to transient Copilot CLI service initialization failure. All workflow infrastructure (MCP gateway, authentication, configuration) operated correctly. The CLI exited after 4 seconds with no diagnostic output.

Failure Pattern

• Success rate: 95% (19/20 recent runs)
• Failure mode: External service unavailability during CLI startup
• Self-resolving: Multiple successful runs before/after this failure
• No correlation: Failures independent of code changes, time, or configuration

Evidence

✅ MCP Gateway: Started, health checks passed
✅ Token validation: COPILOT_GITHUB_TOKEN verified
✅ Configuration: mcp-config.json generated correctly
✅ Network: No firewall denials
❌ Copilot CLI: Exited immediately (code 1, no output)

Recommendation

Close issue #14166 as transient failure. Optional future enhancement: add retry logic (2-3 attempts) to improve resilience from 95% → ~100%.

See /tmp/investigation-summary.md for detailed analysis including logs, success rate data, and retry strategy considerations.
