* Refresh canonical importlib and preserve native import callback Cache the original builtin __import__ callback so CPython 3.15 importlib's hierarchical locking uses the existing native parent-initialization path. Refresh the complete canonical importlib and related test/helper families from CPython d220409a13b77de7a6c30abe16ea90db01528edc through update_lib. Preserve both nondecorator importlib guards in the updater. Add explicit hash-pinned removal of reviewed obsolete canonical files, with full preflight, dry-run, idempotence and refusal tests. Preserve empty fixtures. Assisted-by: OpenAI Codex:model version unavailable * Complete canonical inspect and types closure for importlib metadata Refresh whole canonical inspect/types production and related test families through update_lib after hosted CI exposed stale __cached__ consumers. Add coroutine and async-generator state getters, with closed-state priority for reentrant frame-local finalizers, and expose the existing frame-locals proxy type with its CPython class documentation. Preserve the optional _datetime and unittest import blocks through a narrow migration adapter. Retain canonical assertions and existing guards; record the missing LazyImportType expectation before adding a conditional expected failure, and capability-skip only the two absent-_testcapi CLI fixtures. Assisted-by: OpenAI Codex:model version unavailable * Reject canonical removal junctions and read UTF-8 manifests Reject junctions alongside symlinks in the existing path-component preflight and revalidation. Decode removal manifests explicitly as UTF-8. Add regressions for whole-batch refusal, revalidation, and Unicode dry-run/apply/idempotence. Assisted-by: OpenAI Codex:model version unavailable
