Requires the same current permissions as requesting an export. Only exports
requested by the authenticated administrator are accessible; completed results must also belong to their current firm. Returns
pending (queued or retrying), running, completed, failed, or expired.
Poll every 5–15 seconds. Request a new export after failure or expiry.
Job tracking expires after approximately 48 hours; unknown/expired tracking IDs
return 404. An expired manifest may be reported earlier as expired.

A completed response mints a fresh manifest URL valid for at most 15 minutes and
never beyond expires_at. Poll again to refresh an expired URL while the
manifest is still valid. URL refreshes do not extend the manifest's retention.
completed_at is the firm attachment’s creation time, used to determine cache freshness.
Never use completion time as a file-change cursor.
