A loophole in pull-request approval stamp checking is closed, so malformed stamps get rejected.
What's wrong with this entry?
The anchored-PR stamp checker closes a hole where the create method word could be smuggled in under the wrong key.
- a stamp input carrying the create method word under a non-method key is now rejected
- the catch-all failure message lists the create method word as a third permitted value, next to the PR's identifiers and the approve words
it may only select the connector's create-and-submit operation
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
