Description

lib/SymbolGraphGen believes S “inherits” the nominally public P.f method, even though the protocol and all its members are internal.

Reproduction

protocol P { func f() } extension P { public func f() { } } public struct S:P { }

Expected behavior

lib/SymbolGraphGen should clip the ACL of child declarations to the ACL of their lexical parent.

Environment

swift --version
Swift version 5.10 (swift-5.10-RELEASE)
Target: x86_64-unknown-linux-gnu
