Maintainer (Bernd) accepted 2026-07-30: four rights tiers
(Viewer/Contributor/Operator/Admin) confirmed as proposed. Selected
option (a) - per-human sub-credentials at the Trust Service layer -
over this concept's own recommended option (b), meaning the Trust
Service's signed ledger records can attest to the specific human who
acted, not merely the binky tenant.
This adds a real, firm prerequisite the workplan didn't have before:
extending WP-0006's already-finished licensors/token auth model.
Restructured T02 (was: backend+audit) into T02 (WP-0006 auth
extension, new) + T03 (Control Plane backend, renumbered) + T04
(interactive UI, renumbered) to keep that scope visible as its own
task rather than folding it silently into backend work.
