[`pylint`] Ignore stub files in `import-private-name` (`PLC2701`) Stubs describe the runtime rather than being part of it, so importing a private name is often the only accurate option — re-exporting a private base class, or using the helper types in `_typeshed`. In `.py` files such imports are already exempt when used only in annotations, which does not help stubs where the import may be unreferenced or aliased. Closes #15294 Closes #15295

[`pycodestyle`] Exempt module-level `sys.platform` assertions (`E402`) `assert sys.platform == "darwin"` before an import is a common way to guard platform-specific imports, since a type checker treats it as making the rest of the module unreachable elsewhere. E402 flagged the imports that followed, while the equivalent `if sys.platform != ...: raise` form was already exempt because a top-level `if` block never ends the import section. Accept the checks mypy narrows on regardless of target platform: `sys.platform == "..."`, `sys.platform != "..."`, and `sys.platform.startswith("...")`, alone or combined with `and`, `or`, and `not`. Near-misses are rejected because mypy leaves the module reachable for them — membership tests, a tuple of prefixes, a non-literal operand, reversed operands, chained comparisons, and `sys` reached through an alias or `from sys import platform`. Requiring every leaf of the boolean tree to be a platform check is stricter than mypy, which narrows `sys.platform == "win32" and f()` when checking a non-Windows target; a linter has no target platform to reason from.

[ty] drop atomic bit from state

[`pyupgrade`] Replace `while 1` with `while True` (`UP048`) `while 1:` is a Python 2 idiom from when `True` was a rebindable global that had to be loaded and tested each iteration. In Python 3 both spellings compile to the same bytecode, so `while True:` is strictly clearer. Scoped to integer literals equal to one, including `0x1`/`0b1`/`0o1`. Deliberately not generalized to all always-truthy conditions (`while "always"`, `while [1]`): that would collide with rules meant to catch accidentally-constant conditions. The fix rewrites only the literal's range, so enclosing parentheses and comments survive. It is safe: `True` is a keyword and cannot be shadowed, and no runtime behavior changes. Closes #21870

[`pylint`] Flag chained associative operators (`PLR6104`) Only two-operand assignments were matched, so `x = x * 2 * y` and `x = 2 * 3 * x` were missed. Python parses `a * b * c` as `(a * b) * c`, so the target is found by walking the chain's left spine. Chains are only rewritten for operators that are both commutative and associative. `@` is associative but excluded: `x @= a @ b` builds the full matrix-matrix product first, which can cost orders of magnitude more than the pair of matrix-vector products it replaces. A multi-line operand may only have been valid because the whole assigned value was parenthesized, and those parentheses are dropped with the rest of the statement, so the fix adds its own. This also corrects existing broken output for implicitly concatenated strings. Documents three fix hazards that were previously unstated: comment loss, float regrouping, and NumPy in-place operators rejecting shape or dtype changes that the plain form allows.
