Read an API Response Before Retrying

What you will work through

• Distinguish no response, status, representation and application shape.
• Identify input, authentication, timing and uncertain-write decisions.
• Compute two Retry-After examples without executing a retry.
• Produce a small sanitized report from an explicit field allowlist.

Scope and limitations

• All examples are offline and fictional; no API requests or account actions occur.
• The helper is a bounded fixture classifier, not a universal HTTP parser, secret scanner or production retry engine.
• Timing proposals do not guarantee service recovery or authorize resubmission.
