 **In flight:**
 - [#876](https://github.com/SocketDev/socket-patch/pull/876): registry clients (`build_registry_client`, Maven `fetch_registry_bytes`) built through one `registry_client_builder` under `ApiTimeouts`; `registry_fetch::download` onto `read_capped`. Also ports the base-red digest-ratchet fix for #646's JVM files. Issue #872 (C49). `ready`.

-Re-ranked 2026-10-06T08:58Z: main unchanged, ranking unchanged. No new `arch-audit`/`refactor` issues since 06:56Z; #883 now also overlaps #911 and #927 (PyPI name normalisation). #893 (≈4, `cleanup_blobs.rs`) stays the best eligible; #871 eligible after #889; then #705. 3 of 3 slots used (#876, #886, #889 `ready`, no review questions).

 **Notes:**
 - The sandbox runs as root, so 4 core lib tests fail on main and on branches alike: `copy_tree::relax_loop_must_not_traverse_symlinked_root`, `vlt_heal::an_unremovable_hidden_lock_keeps_every_store_entry`, `pypi_poetry::wire_write_failure_maps_error_and_leaves_lock_untouched`, `pypi_requirements::wire_failure_rolls_back_already_written_files`.
