Changes:

• Adjusted Inline Chat V2 prompt instructions/reminders and selection messaging.
• Renamed the selection markup tag emitted by the inline prompt.
• Refreshed simulation artifacts (baseline/outcome JSONs) and added a new simulation cache layer.

• This reminder repeats the instruction to perform edits via {this.props.exitToolName} (which is inline_chat_exit). As above, this tool is not one of the edit tools and can cause the model to exit without applying changes. Recommend rewording to “make all changes in a single edit-tool invocation” and keep inline_chat_exit only for non-edit/exit paths.

						}
						Do not make code changes that are not directly and logically related to the user's prompt.<br />
						ONLY change the `{filepath}` file, make all changes in a single invocation of the {this.props.exitToolName} tool, and change NO other file.
