Adds durable, identity-neutral, workflow-bound human tasks, and reconciles the
REST surface with the approved Studio contract.
- Flat summary/detail DTOs, a global capability descriptor, and workflow context
captured at activation.
- Scope is part of the list authorization predicate; manager decisions require
manage:user-tasks; a denied command answers 404 so it cannot prove a task exists.
- Guest sessions are task-scoped, action-allowlisted, and revoked when the task
closes. Invitations resolve by token hash through the repository, wait in a
Data Protection encrypted outbox, and are rate limited per caller.
- Masked form values are disclosed only through an audited reveal command.
- Store-specific concurrency failures are translated into a single
UserTaskRevisionConflictException, so a concurrent edit returns the documented
revision-conflict result behind any provider instead of a 500.
EF Core (SQLite, SQL Server, PostgreSQL, MySQL, Oracle) and VNext persistence,
hosted due/reconciliation/delivery workers, docs, and 49 tests.
Note: this branch also carries two commits inherited from its branch point that
are not part of User Tasks and are squashed in here — the revert-version
allocation change from #7917 (WorkflowDefinitionPublisher.RevertVersionAsync now
allocates from the last version rather than the latest) and an NU1903 package
pin. Merged deliberately rather than rebased out.
