Several code paths skipped checks that their siblings already perform.
- Code comment replies are rejected when they target a review of another
pull request or another user's pending review
- OAuth2 refuses tokens for users who can't sign in, and introspection
reports their tokens and already used refresh tokens as inactive
- AGit proc-receive runs the same pull request permission and wiki
checks as pre-receive
- Repository transfer drops the repository's owner-level scoped workflow
source registrations, and registrations whose source the owner no longer
owns are ignored
- The web editor's base branch copy into a fork and the fork's upstream
divergence info require read access to the base repository
- LFS downloads require sign-in under strict `REQUIRE_SIGNIN_VIEW`, like
git smart HTTP
- Unknown AGit target branches are reported as an unexpected ref again
