Create a Matter
There are two real matter lines: Casehall case lead/case surface and native legal matter-core client, matter, and conflict tools.
Casehall business line
The TS SDK exposes:
submitCaseLeadlistMyCaseLeadsgetMyCasesbookConsultationlistMyConsultations
SDK comments describe /casehall/app/* and /casehall/me/* paths. The Go gateway audit did not find those public routes registered directly, so this page treats them as SDK surface and upstream alignment, not a full public gateway promise.
Native legal matter core
Native tools include:
acosmi-legal-archive-matteracosmi-legal-conflict-checkacosmi-legal-matter-gateacosmi-legal-new-clientacosmi-legal-new-matteracosmi-legal-review-queue-createacosmi-legal-review-queue-updateacosmi-legal-source-record-write
A matter needs client, permissions, parties, conflict check, and audit records before substantive work.
