 backend-agnostic, which is exactly what Code Structure Rule 3 was written to
 protect, and it is what a future developer-panel host would bind to. Only the
 ImGui *backend* was deleted. `ACDREAM_DEVTOOLS=1` still selects Vulkan's
 debug-utils extensions and now logs that the developer UI is gone; replacing it
 is issue **#258**, deliberately unscheduled.

 retained gameplay tree, LayoutDesc importer, window runtime, and panel
 controllers. Neither presentation stack owns independent game-state truth.
-Chat submission follows the same rule: both presentation stacks enter the

+Chat submission follows the same rule: `AcDream.Runtime/Chat` owns the shared
+parser, retail command/channel/help catalogs, `ChatCommandRouter`, command bus,
+and its four backend-neutral records (`ExecuteClientCommandCmd`,
+`SendServerCommandCmd`, `SendChatCmd`, and `SendRawChannelCmd`). Its only
+presentation callback is the four-member `IChatCommandFeedback`; retained
+`ChatVM` implements that seam. Both App and Headless bind the same
+`LiveChatCommandRoute` to the active `WorldSession` send delegates and exact
+`RuntimeCommunicationState`/`RuntimeCharacterState` children. Panels never
+inspect or construct wire messages, and Runtime has no UI or App dependency.
+Configured login commands enter that identical parser/router only after the
+generation's `enteredWorld` edge, in order, once per generation. The shared
+generation-aware sequence cancels on replacement, applies the configured
+inter-command delay, and reports each isolated failure without aborting the
+session or plugin lifetime.
 Plugins register retained gameplay markup through the BCL-only
 `AcDream.Plugin.Abstractions.IUiRegistry`; they do not import App or
 presentation assemblies. `IPluginHost.HasUi` is the explicit capability edge:

+The shared chat parser/router/catalog and its four command intents live in
+`AcDream.Runtime/Chat`, not in a panel or App. `AcDream.UI.Abstractions`
+references Runtime so retained `ChatVM` can implement the narrow
+`IChatCommandFeedback` seam and its existing panel input can call the shared
