+## [0.3.1] - 2026-09-04
+
+Bug-fix release: `services/list-peers` can now list peer-announced
+ops. No API breaks — `OperationEnv` gains one defaulted trait method
+(non-breaking for all implementors; `cargo semver-checks` 196 checks
+pass against the 0.3.0 baseline).
+
+### Fixed
+
+- **`services/list-peers` shows each peer's operations**
+  (UP-03, surfaced by alkhttp's review 006). `PeerCompositeEnv`
+  overrode `peer_ids` only, so `peer_operations` fell to the trait
+  default (`Vec::new()`) and every peer listed with an empty
+  operations array — the ADR-022 amendment's "announced op is
+  discoverable via `services/list-peers`" promise never resolved on
+  the wire. ADR-030 prescribed the fix but it had never been ported
+  into alkcall; the existing `list-peers` unit tests passed because
+  they mock `peer_operations` with hand-rolled envs. Implemented per
+  ADR-030: `OperationEnv::list_operation_names` (default `Vec::new()`)
+  + overrides on `OverlayOperationEnv` (overlay map keys),
+  `PeerCompositeEnv` (`peer_operations` delegates to the peer's
+  overlay; its own aggregate mirrors `contains()`: session +
+  connections + base), `LocalOperationEnv` (registry names), and
+  `ChannelsSessionEnv` (delegates to base). Gate:
+  `announced_op_is_discoverable_via_services_list_peers` exercises the
+  exact `compose_root_env` shape (announce via `op/register`, then
+  assert both the `peer_operations` probe and the `services/list-peers`
+  wire shape attribute the op to the peer) — verified load-bearing
+  (reverting the override fails the gate). ADR-030 status is now
+  Accepted with the UP-03 provenance note.
