The curator LLM fork was steered by its own prompt to re-home skill
support files with terminal `mkdir -p ... && mv ...`. A terminal move
writes the same bytes with NO ledger entry, so the archive that follows
snapshots an already-stripped package (files: 1) and `hermes curator
rollback` restores a hollow skill — SKILL.md back, references/ gone.
Remove the capability rather than guard it: the fork's enabled_toolsets
drops "terminal", so terminal and process disappear together and there
is no shell to parse, no process stdin to feed, no remote-backend
divergence — a heuristic command guard over a Turing-complete input
space can guarantee none of that. Every mutation the pass needs has a
ledgered skill_manage action (write_file / remove_file / delete), and
the prompt now steers exactly those. Reading works through skill_view.
Tests pin both halves: the call-site kwarg (["skills"] only), the
resolved surface (no execution/write tools), and the prompt steering
(no mkdir -p / mv shapes).
