The Workflow Normalizer failed because the MCP gateway container couldn't bind to port 80. The container started successfully and configured all MCP servers, but the HTTP server never opened the port after 120 health check attempts over 2 minutes.

Investigation Summary

Failure mode:

• Gateway process alive (PID 11511) throughout 2-minute health check period
• All MCP servers (github, safeoutputs) and 26 tools configured successfully
• Port 80 never opened for connections (HTTP code 000, curl exit code 7)
• No error output to stdout/stderr despite specification requiring it

Root cause:
Port 80 requires CAP_NET_BIND_SERVICE capability. The gateway container running with --network host lacks privileges to bind privileged ports (<1024).

Recommended Fixes

1. Use non-privileged port (8765, 8080, 3000) - eliminates capability requirements
2. Add container capability - Include --cap-add=CAP_NET_BIND_SERVICE in docker run command
3. Investigate gateway binary - Check for regression in ghcr.io/github/gh-aw-mcpg:v0.0.94

Diagnostic Evidence

From workflow run logs:

2026/02/03 03:23:59 Registered 22 tools from github: [github___get_commit github___get_file_contents ...]
Port 80 does not appear to be listening
ERROR: Gateway failed to become ready

Container status showed gateway process running but health endpoint unreachable:

curl http://localhost:80/health  # Connection refused (000)
netstat -tlnp | grep ":80"       # No process listening

This is an investigation PR documenting findings for maintainers. No code changes made - issue requires upstream fix to MCP gateway configuration or image.
