What

The subscribe path now validates requests and refuses ones aimed at cached plugin-marketplace data or at line-append streams, and only serves transcript subscriptions narrowed to a single session. The check is unconditional.

Details
  • Refused: keys or scopes in the marketplace cache namespace, covering the tree, its files and a manifest synthesized from them.
  • Refused: subscriptions to line-append streams.
Evidence

subscriptions to a marketplace tree, its files or a synthesized manifest are not served

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