* scripts: make check_redundant_patches.py executable
The redundant-test-patches pre-commit hook uses `language: script`, which
requires the executable bit, and fails on every commit touching Lib/test.

* csv: support non-ASCII Unicode dialect characters
Store delimiter, quotechar and escapechar as `char` instead of `u8`, and
run the reader state machine and the writer over code points, so that a
single non-ASCII character such as `€` is accepted like in CPython. The
field size limit is now counted in characters rather than bytes.

* Align XML parsing and libraries with Python 3.15
Retain the existing XML backend accounting changes and their explicit registry publication limitation. Preserve canonical XML tests and existing RustPython guards, including multiline marker explanations through update_lib.

* Rebase vendored xml onto 1.4.0
Replace the vendored crate sources with the published xml 1.4.0 archive
and reapply the amplification accounting patch on top of it. The two
lexer hunks that conflicted with the new line-ending normalization are
merged into the 1.4.0 read loop. The patch no longer normalizes CR in
entity values or collapses CRLF in attribute values, because the 1.4.0
lexer and attribute reader already do so.
Update the checksums, recorded upstream commit, archive hash and
provenance notes, and require version 1.4 for the path dependency.

* Remove stale SAX external resolver expected failure
Linux and macOS canonical CI both demonstrate that the existing
unsupported-scheme resolver test passes. Retire only its expected-failure
decorator through update_lib, preserving its canonical assertions.
This does not implement external DTD parsing.

* Support PEP 798 comprehension unpacking
Extract the remaining Python 3.15 comprehension unpacking implementation
from the integration branch. Use existing list/set/dict update operations
and an explicit inner iterator loop for generator unpacking. Align the
public DictComp AST representation and schema with CPython.
Migrate test_unpack_ex and test_unparse with scripts/update_lib from
CPython d220409a13b77de7a6c30abe16ea90db01528edc. Preserve existing Rust tests;
add no duplicate regression tests or snippets.

* Improve selected unpacking diagnostics and refresh canonical exception tests
Normalize six supported comprehension-unpacking diagnostics using existing parser context. Restrict the dictionary-spread hint to its first entry to avoid changing unrelated diagnostics.
Migrate the whole test_exceptions module from CPython d220409a13b77de7a6c30abe16ea90db01528edc with the existing updater, preserving only its two existing RustPython markers. Ruff sources and dependency pins are unchanged.
Six focused check/build/strict Clippy gates passed. A paired 34-input compile-only comparison retains six canonical diagnostic improvements, with eight of fifteen canonical cases still differing; this is not full test_exceptions or CI validation.
* Fix mapping-rest error locations and retire stale encoding xfail
* Match remaining unpacking diagnostics without changing Ruff
Use exact retained AST and error ownership to normalize the remaining CPython 3.15 unpacking diagnostics. Reparse only the owned call argument slice with the unchanged Ruff parser when its original recovery loses generator clauses.
Validated all 30 canonical compile-only cases in exec and doctest-style single modes against CPython 3.15.0, plus finite surrounding controls. Targeted compiler Clippy and source-bound builds passed. Full CI is pending. Cspell alone was omitted with the maintainer’s explicit one-commit approval because its npm bootstrap downloads returned HTTP 403; all other applicable configured commit hooks ran.

A static type with no tp_new of its own whose base is object now gets
DISALLOW_INSTANTIATION instead of inheriting object's tp_new, following
type_ready_set_new. Such types no longer expose an inherited __new__.
A static type that inherits a non-NULL tp_new from its base must have the
same basicsize as that base; type initialization panics otherwise. Types
flagged HEAPTYPE are exempt, like classes created at runtime.
_IOBase is flagged HEAPTYPE so that it keeps inheriting object's tp_new.
FutureIter, TaskStepMethWrapper, hamt, InstructionSequence and
itertools._grouper get constructors of their own.

Keep whole-file and package migration with existing marker, doctest and explicit customization preservation. Retire copy-test and selected assignment/function/export import machinery rather than maintaining extra partial-file update paths.
Remove the separate historical-file deletion command after its migration use. This does not delete any Lib files or make whole-directory migration prune destination-only files; future obsolete-file removal still needs explicit review.
Preserve dependency handling and contributor content-comparison fixes. All 103 retained synthetic migration, patch and copy-library tooling tests pass under an isolated bounded host Python harness. No RustPython runtime or migrated Lib source was executed.

compile_class_body passed firstlineno to source_line_start_range. When
the AST carries an AstLocations table, firstlineno comes from the table,
while source_line_start_range indexes the source text. A table line past
the end of the text panicked in ruff_source_file's line index.
compile_class_def now also computes the text line that the first-line
span starts on and passes it to compile_class_body for the range. The
location still uses firstlineno. Without a location table the two are
the same line.

* Enforce syslog interpreter boundaries and sync queue cleanup
Reject subinterpreter openlog/closelog before audit or host mutation, and
reject implicit syslog opening after audit when the process logger is not
already open, matching CPython 3.15 guard placement and error text.
Already-open logging and setlogmask remain unchanged.
Migrate concurrent/interpreters/_queues.py through scripts/update_lib to
CPython d220409a13b77de7a6c30abe16ea90db01528edc, removing unused eager

on demand; module import timing and debug locals may nevertheless differ.

Extract the unchanged Reader::open decode body into a private owned-buffer
parse helper and add native representation tests for varints, stack depth,

Enable buffer-redux on the workspace rustyline dependency and add its
locked buffer-redux 1.1.0 dependency. Keep existing dependency versions
and checksums, including nix, libc and rustix, unchanged.
RustPython retains a rustyline Editor across interactive prompts. On
Unix, this feature lets a successful readline submission save unread
buffered input for the next read instead of dropping the old reader's
buffer. This is based on the source call chain, not a runtime reproduction.

* Share one target directory between the example projects
Each example project is its own workspace and built into its own target
directory, so the second build recompiled the dependencies the first had
just built. Of the 359 units the frozen_stdlib build needs, 261 are
identical to units of the barebone build.

* Check both macOS cross targets on one runner
macOS runners have the smallest concurrent-job limit of the hosted
runners. The aarch64-apple-ios and x86_64-apple-darwin checks now run in
one job, with one cargo invocation per feature set that passes both
targets, so they also share the host-side build scripts and proc macros.
The matrix entry lists the targets separated by a space, because the
target is part of the cache key and actions/cache rejects commas.
This renames the two "cargo check (macos-latest, ...)" checks to one.

Retain direct IR coverage for constant-pool representations, malformed
append-sequence rejection, and vacated instruction-slot metadata reuse.
Reject non-unit terminal append depths at the private folding helper.
Existing production callers already require depth one; this is defensive
contract hardening, not a newly fixed reachable interpreter bug.
Preserve the existing helper structure and all pre-existing tests. The
three added native tests are unchanged from the Python 3.15 upgrade work.
Validation: codegen check and strict Clippy with --tests, a --lib --no-run
build, and exactly three bounded native IR tests (one pass, zero ignored
each). No Python, parser, VM or lifecycle payload was executed. The
symmetric SetAdd guard has no dedicated depth-two assertion.
