What

Adding a plugin marketplace now runs an admission check before proceeding, and again after a named source is resolved. A disallowed marketplace fails with "Cannot add this marketplace" and an explanation instead of being quietly cached.

Details
  • Part of the normal add flow, with no flag to skip it. What counts as allowed is decided by the admission check itself.
Evidence

Cannot add this marketplace

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