Endpoint Validity

Regeneration failures are silent. An endpoint that has been serving stale or broken JSON for a month looks exactly like one that is fine.

Measures

Each required endpoint parses as valid JSON, carries current protocol and lifecycle fields, and reflects what is actually published.

Data Source

Direct requests to the property's own endpoints.

Indicates

That the structural layer is alive rather than a snapshot from launch day.

What Moves It

Regenerating after every content change rather than treating generation as a one-time setup step.

Does Not Prove

Anything about content quality. This is a plumbing check, and it is the one most often skipped.

Status

Measured. Checked at build and worth re-checking after any content push.
