The deletion did not survive the seam-restore commit, so the exemption
was still in place and the gate was passing on it rather than on
coverage. Measured 76/76 = 100.00% with the gate's own jail flags, in a
detached worktree -- the main tree aborts the jail right now because
another agent is editing python_pkg/endurain_import concurrently and the
tree fingerprint reads that as a write escaping the jail.
