 ### Added
+- `patterm daemon`, `patterm daemon stop`, and `patterm ls` now expose
+  a local unix-socket daemon lifecycle for the daemon/client split.
+- The local daemon protocol now supports attach, explicit detach,
+  project listing, focused-pane snapshots, pane chunks, resize/focus
+  updates, and daemon-owned command spawn requests while keeping child
+  processes alive after a client disconnects.
 - patterm can now keep multiple local projects loaded in one loopback
   daemon core, with command-palette entries to switch the current
   client view or open another project without tearing down processes

+  of always using the daemon registry's default project.
 - Injected agent input now sends the submit Enter as a separated,
   settled keystroke so messages reliably submit instead of sometimes
   sitting unsent in the composer.
