Detail for one error signature
Drill-down for a single error signature, keyed by fingerprint.
Returns summary stats, a time series, top-N breakdowns across the requested dimensions, and recent sample beacons, all in one request.

org_id*Org Iduuidapplication/json- body
Request for drill-down on a single error signature.
Identified by fingerprint (server-computed canonical key), not the
legacy 4-tuple. Backfillable: if the fingerprint rule changes, an
UPDATE rewrites every row deterministically; old request URLs become
invalid by design rather than silently matching the wrong bucket.

meta*Facts about the result
request*The request as the server resolved it
summary*Aggregate summary for the selected error.
error_type?Error TypeThe group's error type, repeated here so the detail reads alone.
""message_kind?Message KindThe group's message shape (selector_invalid, not_defined, ...), collected in every mode. '' when the message is one the customer wrote themselves. The field a diagnosis should be built on.
""message_value?Message ValueThe identifier that shape names, '' when it names none.
""sample_message?Sample MessageOne example message of the group, PII-stripped. Empty when the site does not collect messages, which is the default.
""messages_collected?Messages CollectedEvery application in scope stores error messages, so an empty sample_message means the error carried none. False means the message may simply not be collected.
