A signed-in user is not automatically allowed to read or change every record an endpoint accepts. Authorization has to combine the actor, action, record, and current organizational scope at the server boundary. Lists, files, queued work, and caches need the same constraint. This track follows a case-review application with several tenant organizations and changing reviewer assignments. It tests denial as carefully as allowed access, including after role changes and account switching.
Topics in this track
- Object-Level Authorization for Reads and Writes — Check actor, action, and current record scope for every read or mutation, including list membership.
- Tenant Scope in Cache and Background Work — Carry verified tenant identity into caches, messages, and workers without accepting a client claim as authority.
- Permission Revocation and Active Sessions — Make role and assignment changes take effect across sessions, caches, live streams, and queued work.
- Private Export Authorization and Artifact Scope — Keep export jobs and download artifacts bound to requester, tenant, filter, and expiry.
