A durable API error contract separates machine-readable code, human-readable message, retryable state, optional details, and a traceable requestId. Validate the envelope with JSON Schema, extract batch codes with JSONPath, inventory key paths, compare legacy and target envelopes with Deep Diff, and review migrations with JSON Patch. Public examples are synthetic and must not contain customer inputs, accounts, tokens, logs, or private request identifiers.

Why should API errors keep stable code and requestId fields?
A stable code supports client logic while requestId supports server-side tracing without exposing private logs. Human-readable message text should not drive program flow.
Does this prove search indexing or AI citation?
No. It improves public crawlability and clarity but does not prove indexing, ranking, or citation by any platform.
