+"""User-initiated edit/delete for journey nodes (learned skills + memories).
+
+The journey graph (``agent.learning_graph``) gives every node a stable id:
+
+- **skills** → the skill name (e.g. ``"debugging-hermes-desktop"``)
+- **memories** → ``memory:<source>:<index>`` where ``source`` is ``memory``
+  (``MEMORY.md``) or ``profile`` (``USER.md``) and ``index`` is the node's
+  position in the combined card list (``MEMORY.md`` cards first, then
+  ``USER.md``).
+
+This module maps a node id back to its on-disk home and performs the mutation,
+shared by the CLI (``hermes journey delete|edit``), the TUI ``/journey`` overlay
+(gateway RPCs), and the desktop GUI (REST). Deleting a skill *archives* it
+(recoverable via ``hermes curator restore``); deleting a memory rewrites its
+file. Pure stdlib + existing skill/memory helpers.
