 - **Space-Saving**: Replaces 10–20 rows of `codemode` output with a clean 1-line summary, from the first streamed argument to the final result. Before its first nested call, a running script shows the tools it references; a script without nested tool calls is named by its first code line.
 - **Width-Aware**: Fits the actual rendering area, including shell padding, terminal resizing, and HTML exports. Narrow rows drop the `codemode` title and keep the status.
 - **Key Metrics at a Glance**: Tools used, output line and image counts, execution time, and LLM cost (`$cost`).

 ## Known Limitations
 
-- **Early Progress on Older Pi**: Live timing refreshes after the first partial result. Pi 1.2.0 emits one before the first nested call; older supported versions may wait until a nested tool call begins, and the call row stays in place until then.
-
 - **Static Analysis Approximation**: The call line preview uses a lightweight scanner that skips strings, comments, and regex literals but keeps `${...}` interpolations. Dynamic property accesses (`tools[fn]`) and aliases (`const { read } = tools`) are omitted, and rare regex-versus-division ambiguities may hide or add a name. The result line always displays the authoritative runtime execution history once finished.
 
 - **HTML Exports Keep Two Rows**: The exporter draws the call row before the result exists, so exported sessions still show the call summary above the titled result.
