Codex Desktop: Persistent Plugin Panels and Native Thread Lifecycle/Navigation APIs

What variant of Codex are you using?

26.730.61309

What feature would you like to see?

This confirms that the end-to-end workflow is not currently covered by the documented extension surfaces.
To narrow the request, the plugin can own its taskboard data model, issue storage, dependencies, and cross-surface backend. Codex does not need to provide a complete project-management system.
The remaining Codex-specific extension gaps are:
Persistent Desktop plugin surface
A supported way for a plugin to register a sidebar destination or persistent sandboxed panel in Codex Desktop.

Native thread association and navigation
A supported way to associate an external record with a native Codex threadId and open that thread from the plugin UI.

Desktop thread lifecycle bridge
Stable, permission-scoped events for native thread status, turns, approvals, blocked states, failures, and completion—preferably from the same thread store used by Codex Desktop.

Automation management API
A documented API for plugins to create, inspect, update, pause, and delete Codex automations, rather than relying only on natural-language creation through a Skill.

These capabilities would allow developers to build taskboards and workflow controllers as supported, shareable plugins while keeping task data in their own backend.
Since the existing plugin system and App Server do not currently document these Desktop integration points, I believe this request remains complementary to #36649 and #36694 rather than a duplicate.
Could a maintainer confirm whether these extension points are planned, intentionally unsupported, or available through documentation that is not currently discoverable?
