## What changed
Add `transcript_selected_exec_results` to synchronous Guardian elastic budgeting so selected Code Mode `exec` outputs can receive a separate token reservation and entry cap from ordinary tool evidence.
Configure selection with `nested_tool_names`. Match results against the host-recorded inventory of completed nested tool calls, including normalized tool names, even when the original `exec` call has left review history. Leave the new section's reservation at zero when omitted.
## Testing
Add coverage for recorded-inventory matching and results whose calls are missing from history. Extend the elastic budgeting scenario to verify that selected output is retained while ordinary tool output is capped.
