### Summary An authorization mismatch allowed authenticated callers with `operator.write` access to invoke owner-only tool surfaces (`gateway`, `cron`) through `agent` runs in scoped-token deployments. ### Impact On affected deployments, write-scoped callers could perform control-plane actions beyond intended write scope. ### Fix Owner-only gating is now enforced consistently for owner-only tool surfaces during agent execution, and tool scope classification was tightened to remove the privilege mismatch. ### Affected and Patched Versions - Affected: `<= 2026.2.26` - Patched: `2026.3.1`
