TEST: fictional alert 123
This sample is for teaching. It is not a real warning.
Instruction: No action required.
Sender: demo@example.org. Status: Test.
One alert, different representations
Offline simulation with a fictional Test alert. These are example server policies, not a live endpoint or a universal suffix rule.
Request
Response headers
Returned representation
No supported representation is acceptable. This example returns 406.
A bare wildcard uses CAP by default. Header-first ties use an acceptable suffix, then CAP. Fixed suffixes intentionally bypass Accept. Vary: Accept appears only where the response depends on that field. Real frameworks must handle the complete HTTP grammar.
