@@ -153,6 +153,8 @@ ASSISTANT = {
 - A selected chat template supplies the chat system prompt, profile allowance, predefined user prompt, attachments, and cloned example conversation. A launcher `SystemPrompt`, if retained in an older plugin, is ignored, so there is never a second competing system prompt.
 - When the selected chat template does not allow profiles, the template wins: the launcher `ProfileId` is dropped and the chat starts without a profile. This matches the disabled profile selection such a template produces in the chat.
 - A chat template may preselect tools and data sources as well. When it does, it decides them alone: the launcher `ToolIds` and `DataSourceIds` are dropped, and AI Studio writes a warning into the log naming both sides. The rule is the same for tools and for data sources, so there is only one to remember.
+- A chat template may also preselect a provider and a profile, and the same rule applies: they win over the launcher `ProviderId` and `ProfileId`, with a warning in the log. A provider of the template which is gone or does not meet the confidence level required for chats, and a profile of the template which is gone, are left out instead of stopping the launch; the launcher then decides as if the template named none.
+- A chat template may name a workspace for its chats as well. Here the launcher wins when it names a workspace of its own, because that choice was made on purpose. A launcher that opens a disappearing chat opens it in the workspace of its template instead, which is created when it does not exist yet; if that fails, the chat stays a disappearing chat.
 - The reason the template wins as a whole rather than field by field is a difference in what the two can express. A launcher can only ever say "these sources, picked by hand", while a chat template carries the whole data source options and can also say "let an agent pick the sources for each message". A mix of both would be something neither of them asked for.
 - The data sources of a chat template are checked exactly like the ones of a launcher: a source which no longer exists, or which is not permitted for the effective provider, stops the launch before a workspace or chat is created. The message then names the chat template as the cause, not the launcher. A template which leaves the choice to an agent names no source and is therefore not checked here; that decision is made per message in the chat.
 - The predefined user prompt and the attachments of the selected chat template are placed into the chat input, unless the user already has an unsent draft there.
