Runs one suite unchanged against every implementation of IUserTaskRepository,
IUserTaskGuestSessionIssuer, and IUserTaskInvitationOutbox, plus a fault-injection
suite driving the real DefaultUserTaskManager and DefaultUserTaskInvitationService
against a real store. Gated providers report as skipped with a reason rather than
passing vacuously; ConformanceCoverageTests fails when a provider that must run is
unreachable or its variable is set but empty.
The suite found three defects, fixed here:
- VNextUserTaskRepository supplied no index values for WorkflowDefinitionId,
WorkflowInstanceId, ActivityInstanceId, CreatedAt, or CompletedAt, all declared by
its own schema provider, so every write through the VNext provider threw.
- The same provider resolved invitation token hashes by scanning on Status alone,
which matched no declared index, so anonymous invitation verification always threw.
- EFCoreUserTaskInvitationOutbox persisted the delivery recipient but never read it
back, so durably queued invitations reached the dispatcher with no address.
Also switches new ADRs to date-prefixed identifiers and generates doc/adr/toc.md via
scripts/adr/generate-toc.sh, with a --check mode and pull-request workflow so the
index is never hand-edited again.
