Bash safety classifier flags deletions whose scope is only decided at run time

The shell safety check now flags deletions whose targets are computed at run time, like remote or cloud resources.

What

The rule set that judges shell commands before they run gains an Unverifiable Deletion Scope category, covering deletions against shared or remote state such as cluster resources, cloud storage or remote git refs where the set of things removed is not fixed until the command executes. It catches the case where the target is computed rather than named, so the scope shown at approval time is not the scope that actually gets deleted.

Details
  • The new category is named unverifiable_deletion_scope and sits immediately before the existing unverifiable_deletion_target, in the same list as traffic_redirection and untrusted_code_integration; before this, such commands had to be squeezed into the target category or went uncategorized.
  • Fires when the deletion target comes from a variable, from a command substitution, or from a get ... | grep ... | xargs <delete> pipeline.
  • The rule states that approving such a command authorizes the scope you were shown, not whatever the target set turns out to match at run time.
  • The rule states that a dry run whose output does not appear in the transcript verifies nothing.
  • Does not fire for deletions confined to the agent's own local filesystem.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
