 ## Done
 
+- **Steamify Summary** (2026-09-28, ISO VM): an unordered list of the chosen
+  items' names plus "Starts in gaming mode/the desktop"
+  (`patches/packagechooserq-steamify-summary.patch`), with `items.json`
+  written by the launcher (its `$sdir` bug fixed, `0cc7367`).
 - **packagechooserq built with the ISO** (2026-09-28):
   `build-calamares-modules.sh` builds it in the build container/VM from
   CachyOS's Calamares source against the current `cachyos-calamares-next`
