summary: List legal records (filter, sort, paginate)
description: 'TIER-GATING: filters and sorting (scope, jurisdiction, status, in_force, updated_since, sort, order) are honoured at EVERY tier including anonymous — they are documented query semantics, so they are never silently dropped. What Free/anonymous callers get instead is low volume and shallow pagination: anon 5 rows per page with a trimmed field envelope, free-key 25 rows with the full field set. Developer+ raises the page size and unlocks deep pagination, the change feed and per-record history. When a request is capped, the response echoes meta.gated + an upgrade hint (it is never a hard error).'
