 The account's Jira permissions determine its issue visibility. This bounded
 owner path does not delegate the deployment account to other Von users or
 release Jira writes. Explicit trusted-local operator access remains separate.
+The local stdio `jira_create_issue` entry point preserves that operator
+provenance through its nested issue-type preflight; standalone
+`jira_get_project_issue_types` uses the same boundary. Existing actor or
+untrusted invocation context is never promoted to operator. Creation still
+requires the coding-agent write gate, project allow-list and explicit write
+intent. This does not grant Jira creation to ordinary browser turns.
 Missing or ambiguous identity binding fails closed, and a changed credential
 configuration cannot silently reuse the previous account's proxy.
