Found live: a chat request to restart caddy (the reverse proxy for the
whole fleet) executed instantly over SSH with zero approval. Root
cause was in request_execution's legacy handler — restart, pct_exec,
and systemctl (outside enable/disable) executed immediately with a
hardcoded risk_class='reversible_low' that was never actually checked
against anything, bypassing the classifier entirely. Only the `run`
tool's commands were ever gated.
Extracted the run tool's classify -> execute-or-queue logic into a
shared classifyAndGate() and route restart/pct_exec/systemctl through
it too, so every mutating path — regardless of which tool the model
reaches for — gets the same read-only/config-mutation/destructive
classification and approval gate. systemctl restart is already covered
by an existing classifier test (config_mutation), so no new test
needed; the gap was that request_execution never called the
classifier at all.
