A real editing buffer (CodeMirror 6). Pick your keybindings; it holds the actual verified deprovisioning spec. Next: select any text and query the on-prem model about it, inline.
Vim: i insert · / search. Emacs: C-a/C-e, C-k, M-w.
VS Code: ⌘D multi-cursor · ⌘/ comment · ⌥↑/↓ move line.
Select any expression → ⇧⌘E or "✦ Explain selection" → the on-prem model explains it, grounded in the corpus.
