+## Lease visibility (#433)
+
+`/leases` surfaces read-only lease and collision state: local issue lock file,
+in-progress claim inventory (#268), reviewer PR lease comments when present
+(`<!-- mcp-review-lease:v1 -->`, #407), duplicate open PRs per issue (#400),
+and duplicate local branches per issue. Links to collision-history backend
+issues (#267, #268, #400, #407) are included. No lease acquire/release from UI.
+
+## Runtime health (#430)
+
+`/runtime` surfaces read-only MCP/runtime diagnostics for the default registry
+project: active profile and role kind, authenticated identity (when credentials
+are available), config model/mode, local vs remote `master` SHA sync, shell
+health, workflow/schema SHA-256 hashes, and stale-runtime warnings when the
+checkout is behind merged safety-gate changes. Restart guidance links to #420;
+no tokens or MCP restart actions are exposed.
