Get Authority Summary

The generated case_summary record for an authority, if one exists.

An absent summary is 200 with an empty object, not 404. 2,976 of 348,212 authorities have one this endpoint will serve, so "there isn't one" is the ordinary answer for essentially every case page. Returning 404 would make the normal path an error: the client would have to treat a successful, correct response as a failure, and every case page load would log one.

Two things make a record unservable, and both read as absence rather than as an error, because from a reader's side they are the same fact -- there is no summary to show. A record is withheld if it is stale (its anchors point into a parse the judgment no longer has) or if it is heuristic template output rather than a model's writing. 15,132 records are the latter.

A 404 here means the AUTHORITY does not exist, which is a different fact and the only one worth erroring on. The same quarantine gate as every other authority read applies, so a case this API will not show is not-found rather than summary-less.

case_summaries_current picks the newest run per authority. Older runs stay in case_summaries and are not served: comparing generations is a review job, not something to hand a reader.
