Clank 0.19.1 fixes MCP Apps rendering in stateless hosts such as Codex.

  • Model-visible tools now retain _meta.ui.resourceUri even when a host omits the per-request MCP Apps capability hint.
  • Codex can associate a tool result such as dailyLog_getDay with its published ui://daily-log/daybook resource automatically.
  • App-only tools remain hidden and uncallable unless MCP Apps support is negotiated.
  • OAuth scopes, user isolation, server authorization, and resource security policy are unchanged.

Validated with 687 tests, 100% coverage, CodeQL, security and documentation audits, and packed deployment/migration/rollback conformance.
