* Implement _collections.OrderedDict
Extracted from #6799: native OrderedDict as a dict subclass,
iterator mutation tracking, and mapping-view set operations.
* Add OrderedDict, warnings source lines, and socket sendmsg
Implement _collections.OrderedDict as a dict subclass with a
linked list of insertion-order nodes.
Pack struct F/D as native float/double complex pairs, and report
unexpected __replace__ field names as a list repr.
Register encodings.latin_1 at startup. Reject NUL in input()
prompts. Copy non-exact type dicts in mapping order.
Fetch warning source lines through _bless_my_loader and unicode
splitlines. Keep the last warnings.filters list after deletion.
Snapshot sendmsg sequences before converting buffers, parse
ancillary ints with __index__, and dispatch AF_CAN by protocol.
Store sys.trace and sys.profile on each ThreadSlot so
_settraceallthreads/_setprofileallthreads are visible to
sys.gettrace/getprofile on other threads.
Use <frozen importlib._bootstrap> as frozen importlib
co_filename. Keep HEAPTYPE socket objects GC-tracked.

* Load marshal via readinto and dump sets in dumps order
marshal.load fills a scratch buffer with readinto on a
contiguous writable memoryview, and rejects a returned length
other than the requested size.
set and frozenset dumps write elements in sorted(v,
key=marshal.dumps) order.

* Add classmethod_descriptor and ABC IS_ABSTRACT flags
Give METH_CLASS methods a distinct classmethod_descriptor type.
Store Py_TPFLAGS_IS_ABSTRACT from __abstractmethods__ and look
up that attribute only in the type's own dict.
Expose defaultdict.default_factory as a member descriptor.
Inherit bool's unused number slots from int. Mark set and
frozenset __contains__ as METH_COEXIST.
Parse classmethod, staticmethod, object.__new__, and heap type
text signatures. Register interactive source in linecache.

* address review: odict reuse, descr call, new wrapper
Reuse odict node slots and walk the live list in next_after.
Require both | operands to be dicts. Drop the odict iterator
on GC clear. Bind classmethod descriptors through descr_get
and update IS_ABSTRACT under the type lock. Give odict keys
and items sq_contains. Walk tp_new_wrapper past new_wrapper
so HEAPTYPE socket subclasses can call socket.__new__.
Split FreeBSD Bluetooth protocol constants from Linux values.

* Add pickle and os.stat inspect signatures
Give _pickle.Pickler the clinic constructor text signature and
accept fix_imports and buffer_callback as positional-or-keyword.
Allow #[pyfunction(text_signature)] and use it so os.stat reports
(path, *, dir_fd=None, follow_symlinks=True). Uncomment import
_pickle and drop the pickle inspect expectedFailures.

* Add Unpickler, dump/load, and lstat signatures
Give _pickle Unpickler, dump, dumps, load, and loads clinic
text signatures, and os.lstat (path, *, dir_fd=None).

* Complete OrderedDict with insertion-order links
Move the native OrderedDict into ordered_dict.rs and track order
with a linked list of nodes, keeping mapping-view set operations.

* address CI: stat casts, HCI_DATA_DIR, passing xfails
Compare stat permission bits as Mode so Linux clippy does not
flag a u32-to-u32 cast. Export HCI_DATA_DIR with the Bluetooth
socket option values. Drop expectedFailure from tests that now
pass.

* Add cmp_to_key and hash-once LRU cache
_functools.cmp_to_key now returns KeyWrapper. LRU lookups store the
key hash on _lru_list_elem so __hash__ is not called again on hits
or eviction.

* Allow subclass keywords on list, tuple, and float
list.__init__ rejects keywords only when tp_new is still list's.
tuple/float.__new__ reject them only when tp_init is still the base's.

* Fix CI lint, test re-export, and structseq members
Drop the duplicate clear_eval_breaker_for_test re-export.
Format structseq imports. Expose struct sequence fields as
readonly members so assignment raises "readonly attribute".

* Allow subclass keywords on itertools and filter
Positional-only constructors ignore extra keywords when a subclass
has replaced tp_init, matching list/tuple/float.

* Remove text_signature derive parameter

are generated from the Rust parameter list only. Restore inspect
expectedFailures that depended on the override.

drain the source up to stop.

* SETREF warnings filters, onceregistry, and defaultaction
Keep the last list, dict, or str after the module attributes are
deleted by swapping the interpreter cache pointer. Do not store a
None fallback for _warnings_context.

* Object header slimming: prefix allocation for ObjExt
Extract dict, weak_list, and slots fields from PyInner<T> into a
separate ObjExt struct allocated as a prefix before PyInner using
Layout::extend(). Objects that don't need these fields (int, str,
float, list, tuple, dict, etc.) skip the prefix entirely.
- Add HAS_WEAKREF flag to PyTypeFlags for per-type weakref control
- Add HAS_EXT bit to GcBits indicating prefix presence
- Define ObjExt struct with dict, weak_list, slots
- Shrink PyInner header from ~80-88 bytes to ~32 bytes for lightweight objects
- Update all accessor methods to go through ext_ref()
- Update bootstrap type hierarchy to use prefix allocation
- Add __weakref__ getset descriptor for heap types
- Set HAS_WEAKREF on builtin types that support weak references
- Remove test_weak_keyed_bad_delitem expectedFailure (now passes)
* Add HAS_WEAKREF to _asyncio Future/Task, rename weakref helpers
- Add HAS_WEAKREF flag to PyFuture and PyTask (matches CPython)
- Rename subtype_getweakref/setweakref to subtype_get_weakref/set_weakref
to fix cspell unknown word lint
* Add HAS_WEAKREF to array, deque, _grouper; remove expectedFailure markers
- Add HAS_WEAKREF to PyArray and PyDeque (matches CPython)
- Add HAS_WEAKREF to PyItertoolsGrouper (internal use by groupby)
- Remove 6 expectedFailure markers from test_dataclasses for weakref/slots
tests that now pass
* Add HAS_WEAKREF to code, union, partial, lock, IO, mmap, sre, sqlite3, typevar types
Add HAS_WEAKREF flag to built-in types that support weakref:
- PyCode, PyUnion, PyPartial, Lock, RLock
- All IO base/concrete classes (_IOBase, _RawIOBase, _BufferedIOBase,
_TextIOBase, BufferedReader, BufferedWriter, BufferedRandom,
BufferedRWPair, TextIOWrapper, StringIO, BytesIO, FileIO,
WindowsConsoleIO)
- PyMmap, sre Pattern, sqlite3 Connection/Cursor
- TypeVar, ParamSpec, ParamSpecArgs, ParamSpecKwargs, TypeVarTuple
Remove 3 expectedFailure markers from test_descr for now-passing tests.
* Add HAS_DICT to type flags and handle non-METHOD/CLASS in descr_get
- Add HAS_DICT flag to PyType (type metaclass) alongside existing
HAS_WEAKREF. All type objects are instances of type and need dict
support, matching CPython's PyType_Type.
- Replace unimplemented!() in PyMethodDescriptor::descr_get with
fallback to bind obj directly, matching CPython's method_get which
uses PyCFunction_NewEx for non-METH_METHOD methods.
* Fix ext detection, HeapMethodDef ownership, WASM error
- Remove HAS_EXT gc_bits flag; detect ext from type flags
using raw pointer reads to avoid Stacked Borrows violations
- Store HeapMethodDef owner in payload instead of dict hack
- Clear dict entries in gc_clear_raw to break cycles
- Add WASM error fallback when exception serialization fails
