@@ -62,6 +62,7 @@ Docs: https://docs.openclaw.ai
 - Plugin SDK: add bundled-plugin session actions, `sendSessionAttachment`, and Cron-backed `scheduleSessionTurn`/tag cleanup under the grouped session namespace. Replaces #75578/#75581/#75588 and part of #73384/#74483. Thanks @100yenadmin.
 - Plugin SDK/media-understanding: add `extractStructuredWithModel(...)` plus the optional provider-side `extractStructured(...)` seam so trusted plugins can run bounded image-first structured extraction with optional supplemental text context through provider-owned runtimes such as Codex.
 - Exec approvals: add `tools.exec.commandHighlighting` so parser-derived command highlighting in approval prompts can be enabled globally or per agent. (#79348) Thanks @jesse-merhi.
+- Codex app-server: mirror native Codex subagent spawn lifecycle events into Task Registry so app-server child agents appear in task/status surfaces without relying on transcript text. (#79512) Thanks @mbelinky.
