Recovers a wheel's ``METADATA`` by ranged reads of the remote ZIP when the index publishes no PEP 658 sidecar. The reader drives an :class:`~nab_index.transport.AsyncHttpTransport`, learns each host's range capability once per run through a shared :class:`RangeCapabilityMemo`, and navigates the ZIP with the standard library's :class:`zipfile.ZipFile` over a sparse buffer so no EOCD scan, deflate, or CRC logic is hand-rolled. Two kinds of exception travel outward: a :class:`~nab_index.client.MalformedSimpleResponseError` for METADATA bytes that are not valid UTF-8, and the transport's error when the wheel URL itself cannot be served (a 404 on the file, a failing plain GET). A server that merely refuses the Range mechanism is stepped down instead, from a suffix range to absolute ranges to a plain full-body GET. Every other failure to obtain metadata returns a result whose ``text`` is ``None``. ) annotationsN) dataclass) TYPE_CHECKING)urlsplit)MalformedSimpleResponseErrorWheelHashMismatchError)UnsupportedWheelErrorwheel_metadata_member)IDENTITY_HEADERS)NormalizedName)AsyncHttpTransport HttpResponseRangeCapabilityRangeCapabilityMemoRangeMetadataResult RangeOutcomei(iiiizbytes\s+(\d+)-(\d+)/(\d+)c*]tRt^BtRtRtRtRtRtRt R#)rz=How rung 4 obtained (or failed to obtain) a wheel's METADATA.partial full-body unsupportedmissingN) __name__ __module__ __qualname____firstlineno____doc__PARTIAL FULL_BODY UNSUPPORTEDMISSING__static_attributes__rf/home/user/pdf2html-billing-ledger-validate/.venv/lib/python3.14/site-packages/nab_index/lazy_wheel.pyrrBsGGIKGr"T)frozenslotsc0]tRt^Kt$RtR]R&R]R&RtR#)rz=The recovered METADATA text and the outcome that produced it. str | NonetextroutcomerN)rrrrr__annotations__r!rr"r#rrKsG  r"c.]tRt^StRtRtRtRtRtRt Rt R#) raThe request shape to lead with on a netloc, monotonic toward more restrictive. ``SUFFIX_OK`` is optimistic: a host that volunteers a 200 full body for a suffix range stays ``SUFFIX_OK``, since leading with the suffix form again costs the same single request while a proxy that only ignores ranges while filling its cache gets to serve cheap partial reads again. ``FULL_BODY_ONLY`` is for hosts that, once the suffix form was already unusable, refused or ignored ranges or honoured one without reporting a complete-length; their wheels are fetched whole.
