Published PR review pages now carry an approve action, and republishing can't quietly change it.

What

A composed PR review artifact now ships an approve script and a stamp island recording the approve binding, and republishing is checked against it.

Details
  • The artifact includes an approveScript plus a stamp island holding the approve binding.
  • Validation rejects a republish that changes the binding.
  • All approve-binding validation messages are new in this build.
Evidence

a republish must reuse the published stamp island exactly

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