What

The refusals you get when a shell cwd or file edit escapes a worktree now name the right subject.

Details
  • picks between "This session is isolated…" and "This agent is isolated…" based on whether the pin is the session's own worktree, with a matching possessive
  • shell cwd and file edit paths now share one escape-detection routine
Evidence

possessive: "a worktree-isolated agent's"

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