Shell UI Command and Deferred Work Flow

  • Roots: shell callback paths that converge on shell_dispatch_ui_command at 0x00464410.
  • Trigger/Cadence: event-driven UI command dispatch plus deferred-message queue flushing during shell activity.
  • Key Dispatchers: shell_dispatch_ui_command, shell_enqueue_deferred_work_message, shell_post_deferred_message_type5, shell_post_deferred_message_type6, shell_enqueue_deferred_message_type4, shell_enqueue_deferred_message_type1.
  • State Anchors: shell object at 0x0062be68, queue roots around [this+0x11369d], [this+0x1136a1], and [this+0x1136a5], global routing gates at 0x006d4034, and the separate detail-panel controller rooted at 0x006d0818.
  • Subsystem Handoffs: routes into graphics config, scenario-text export, overlay generation, multiplayer UI, shell detail windows such as EditorPanel.win and TrainDetail.win, and presentation-facing deferred work later drained by shell_service_frame_cycle.
  • Evidence: function-map shell rows around 0x00464410, 0x004d4500, 0x004ddbd0, and 0x0051f1d0..0x0051f460.
  • Open Questions: whether the shell command dispatcher is also used by hotkeys or only by UI callback tables; the current 0x006d0818 detail-panel path looks shell-only and does not yet explain gameplay world entry.
