DELETE /api/heartbeat to trigger 405

Lessons Learned

• DELETE /api/heartbeat reaches a real endpoint with a disallowed method, causing 405 Method Not Allowed.
• 405 Method Not Allowed is different from 404 Not Found because the resource exists but the method is not supported.
• The raw response status line is useful when teaching method-level failures.

Suggested Experiments

• Compare DELETE /api/heartbeat with GET /api/heartbeat and inspect both raw status lines.
• Check whether the Allow header explains which methods /api/heartbeat accepts.
