 # @agentruntimecontrolprotocol/client
 
+## 2.0.0

+### Minor Changes
+
+- 543b38b: Surface a job's authority descriptor to subscribers (§7.6).
+
+  The runtime now populates `budget` (current per-currency counters) on
+  `job.subscribed`, alongside the `lease_constraints` it already sent, so an
+  observing principal can render a job's authority surface — the expiry clock
+  and budget gauge — without being the job's submitter. The cap is derivable
+  from the lease's `cost.budget` pattern; subsequent `cost.budget.remaining`
+  metric events keep the gauge live.
+
+  The client's `JobSubscription` now exposes the full descriptor:
+  `currentStatus`, `agent`, `lease`, `leaseConstraints`, `budget`, and
+  (submitter-only) `credentials`. Credentials remain redacted for non-submitters
+  per §14. Backward-compatible — only additive fields.
