A Python class with a parameterized base had no extends edge. The grammar parses Base[str] in a base list as a subscript, and the base-list reader took only bare identifiers and attributes, so the base was skipped, on the wasm path and in the kernel alike. Everything that follows the class hierarchy missed such a class. The resolver's own text reader of a base list, pythonBases, also looked up Base[str] verbatim and split Pair[str, int] at its inner comma, so current = Leaf() then current.run() did not reach Base.run. A subscript base is now unwrapped to its value before the identifier or attribute check, in src/extraction/tree-sitter.ts and in the kernel's python.rs. pythonBases drops bracketed type arguments before splitting the list. Generic[T] and Protocol[T] stay outside the project like their plain forms; a computed base, a subscript of a subscript and keyword arguments link nothing. Validation: - The test file runs on both arms: red on main's source and kernel (12 of 16 fail, 6 per arm), green here (16 passed). - Kernel parity with this kernel on 3,155 Python files of flask, requests, mypy, litestar, sqlalchemy, polar and django: 0 diffs, and the same 5 files defer to wasm as on main. The kernel and wasm edge dumps of the repos run both ways are identical. - A/B against main on 7 Python repos, 457,948 edges: 1,492 added (901 extends, 555 calls, 36 references), 0 removed, 607 call sites moved, 223 kept their target with higher confidence. polar: 491 self.get_one_or_none() style calls move from the protocol stub RepositoryProtocol at 0.4 to RepositoryBase and its mixin at 0.9. litestar: 12 calls in GenericSyncMockRepository move from AbstractAsyncRepository to AbstractSyncRepository. sqlalchemy: 435 extends and 554 calls added, like t.insert() reaching TableClause.insert. We read 44 sampled changes and every small bucket. They read right, except 12 self.op() sites that move to the typing-only overload SQLCoreOperations.op and one Enum.copy that moves to TypeEngine.copy. - 3 of the 901 extends are wrong: sqlalchemy's Sequence[_T], Tuple[int, ...] and MutableSet[_T] from typing link to its own classes of those names. The plain form does this on main (28 class X(Enum) there), and none of the 3 brought a call edge. - Controls express and gin: full dumps byte-identical. - Index cost with PR #3001 on top, sqlalchemy, median of 3 interleaved: 23.7 s on main, 25.2 s here, with 1,143 more edges.
