Restrict mappingproxy ordering, use final codec registry normalization, and prefer index conversion before float conversion for sleep. Retain universal Python assertions and import the matching final codec/time canonical test hunks plus the non-ASCII codec-name deprecation warning.
Upstream source: CPython d220409a13b77de7a6c30abe16ea90db01528edc. The existing codec normalization implementation and bytecode contract remain unchanged.

* Track live entries in reverse dictionary iterators
Extract the Python 3.14-compatible remaining-count and same-size storage handling from #8954.

* Support compile module context across AST warning paths
Add Python 3.15 compile(module=...) warning filtering. Move format-spec diagnostics to a fallible, literal-aware AST boundary; preserve nested literal warnings while excluding raw text and comments, map function-type fragments to source locations, and suppress duplicate type-comment emissions with per-call tracking.

* Reject unsupported native keywords before argument binding
Add explicit keyword dispatch metadata independently of inferred Rust
calling flags. Reject nonempty keywords before binding and conversion,
while preserving descriptor self checks and keyword-capable calls.
Annotate 31 builtins and list.append/list.clear, derive C-API policies
from ml_flags, and group dynamic registration metadata in MethodDefSpec.
Add regression coverage and remove the id doctest expected-failure marker.
Validation: workspace and C-API tests/clippy, VM without doc, keyword
regressions, and test_call/test_extcall/test_builtin/test_list passed.
The full snippet suite had 475 passes and 7 failures: six CPython-side
expectation mismatches and one missing optional SQLite module.

* Infer native keyword dispatch from argument metadata
Replace no_keywords annotations with registration-time inference from
FromArgs::PARAMS, including nested parameter metadata. Forward arguments
with keyword-capable parameters to the binder, preserving min/max body
validation and descriptor self checks.
Add regressions for raw arguments, keyword argument structs, and list.sort.
Tested: C-API tests, workspace and C-API Clippy, VM without doc, both keyword
regression snippets, and test_call/test_extcall/test_builtin/test_list.
Workspace tests reported eight _opcode snapshot failures. The full snippet
suite reported 477 passes and seven failures: six CPython-side failures
and one RustPython failure due to the missing optional SQLite module.

* Simplify native function registration metadata
Reuse SimpleItemMeta for pyfunction attributes and remove FunctionItemMeta.
Remove MethodDefSpec and restore the original new_method_def arguments

Consolidate keyword dispatch regressions in syntax_function_args.py,
preserving their assertions and placing them before builtin shadowing.
Validation: workspace and C-API tests/clippy, VM without doc, the combined

The full snippet suite reported 477 passes and seven existing failures:
six CPython-side failures and one missing optional SQLite module.

* Reject native keywords by calling convention flags
Remove `KeywordDispatch`, the `keyword_dispatch` field of `PyMethodDef`,
`PyMethodDef::with_keyword_dispatch`, `function::keyword_dispatch` and
the derive macros' `keyword_dispatch_tokens`. Native functions and method
descriptors reject nonempty keywords when `flags` lacks `KEYWORDS`, and
report the unqualified name when `flags` contains `VARARGS`.
`Context::new_method_def` takes `(name, f, flags, doc)` again. Add a
snippet for `int.__new__` called with a keyword argument.

* Cover Windows time conversion error classes
Require OSError with EINVAL for representable timestamps rejected by the Windows C runtime, while preserving OverflowError for float(2**63). This initial regression-only commit intentionally exposes the current Windows error mapping before the implementation follows.
AI assistance covered source comparison, regression design, and automated Linux baseline/reference controls. Native Windows results are pending. No human validation is claimed.
Assisted-by: Codex:model-version-unavailable
* Record native Windows time conversion outcomes
The first hosted regression run failed on CPython 3.14.7 as well as RustPython because a presumed-invalid CRT timestamp succeeded. Add bounded diagnostics before the unchanged assertions to capture full version/build metadata and every conversion result, including negative half-day controls. No implementation or canonical test changes are included.
The existing time snippet still passes the repository pytest runner on Linux CPython 3.14.7 and the current RustPython baseline. Native diagnostic results remain pending.

* Use the observed UCRT rejection boundary in time regression
Hosted Windows diagnostics show that CPython 3.14.7 and RustPython both accept gmtime(-1) and gmtime(-43200), while -86400 is rejected by all three converters. Correct only the newly added shared negative test value. CPython raises OSError(errno 22) for every selected rejected value, while the RustPython baseline raises OverflowError. Canonical tests and the recorded diagnostics remain unchanged.
The existing snippet passes both Linux reference and baseline controls. Assisted source investigation and automated verification used no manual validation.
Assisted-by: Codex:model-version-unavailable
* Preserve Windows CRT time conversion errors
Return CRT errno failures from the Windows calendar helpers and translate them to Python OSError. Adapt the datetime caller while retaining its Unix behavior. Use an exclusive signed float upper bound so float(2**63) still raises OverflowError before reaching the CRT.
Keep Windows negative-time FILETIME fallback and time64 ABI changes outside this Python 3.14 extraction. Existing datetime local-error coverage is retained and a UTC error control is added for the observed rejected timestamp -86400.
Hosted native diagnostics prove CPython 3.14.7 raises OSError(errno 22) where the baseline raises OverflowError. Windows-GNU host_env check and warnings-denied Clippy pass. Selected canonical datetime and complete time/datetime snippet Linux controls pass, with six existing baseline canonical skips. Fixed native Windows verification remains pending CI.
AI assistance covered source comparison, implementation, regression design, and automated verification. No manual validation is claimed.

* Use immediate exit for host process termination
Python os._exit, failed child exec and fatal/watchdog exits must bypass C exit handlers. Call the host CRT _exit on Unix, Windows and WASI while retaining the existing non-host fallback. Normal interpreter termination is unchanged.

`PyMethodDef::new_const`, `PyMethodDef::new_raw_const` and
`Context::new_method_def` add the calling convention (`NOARGS`, `O`,
`FASTCALL`, or `FASTCALL | KEYWORDS`) inferred from the
`FromArgs::PARAMS` of each argument, exposed as `IntoPyNativeFn::ARGS`.
Flags that already contain a calling convention, such as C-API
`ml_flags`, are kept. For `METHOD` and `CLASS` the first argument is the
bound receiver. Raw functions get `FASTCALL | KEYWORDS`.
The derive macros pass only binding flags and no longer infer call flags
from Rust type names. Definitions built without the macros, such as the
`__new__` wrapper and `vm.new_function`, get calling convention flags the
same way.

Split `builtin_method` out as a subclass of `builtin_function_or_method`.

- bytearray: keep the buffer exported while converting the needle of

separator, so resizing from there raises BufferError
- str(): report non-str encoding/errors as "str() argument 'X' must be
str, not T", and check argument counts and name/position duplicates
for keyword calls
- _json.scanstring: take end as a signed integer and raise ValueError
when it is out of bounds
- lzma: reject filter specs with keys the filter does not take
- mmap: raise ValueError when growing a shared anonymous mapping on
Linux/NetBSD
- _sqlite3: check that the backup progress argument is callable
- Remove the expectedFailure markers of the tests these fix

* Reject arguments given by name and position in FuncArgs::bind_for
bind_for reports a keyword that fills a parameter already given by
position before other binding errors, using the parameter list of the
FromArgs type. getargs shares the message, str() drops its own check,
and blake2b/blake2s name themselves in binding errors.
