The class-body initialization check is extracted into #5344, which is based directly on main and can land independently. This PR retains the complete implementation, including instance initialization, while the smaller change is reviewed.

Fixes #4318.

Add possibly-uninitialized-attribute for attributes whose class body or initialization method can complete without assigning them. Report the error at the definition. The default preset ignores it, and the strict preset enables it. Users can configure it separately from missing-attribute.

Track attribute initialization separately from local-variable bindings. Check class-body definitions independently. Combine method assignments leniently, so an unconditional helper assignment can establish initialization. Exclude conditional method definitions, stub files, nested-function assignments, inherited attributes, and instance attributes with a __getattr__ fallback. Account for explicit returns, deletions, and paths that terminate with Never or NoReturn.

Preserve exact deferred termination conditions through 16 requirements. Above that limit, retain one key per requirement and remove duplicates. This prevents exponential growth across branch joins. The conservative approximation can produce false positives above the limit.

Changes to local-variable initialization are in #5323. The loop reachability fix from #5324 is present in main and remains unchanged in this PR. The retry-loop initialization test passes without a bug marker.

Validation:

  • The complete Rust library suite passed: 9,334 tests passed, 3 ignored, and 0 failed.
  • Regression tests cover the proof limit, 1000 successive joins, and branch-heavy constructors and helpers with the diagnostic enabled and disabled.
  • Formatting and lint checks passed. Clippy reports existing warnings in unchanged code.

hmm, for this one I think we should error where the attribute is declared, not where it is accessed. it could be kind of tricky because we would need to handle situations like this to avoid false positives.

if something:
   self.x = 1
else:
   self.x = 2

I guess it would be similar to the logic around possibly-unbound variables

Preserve missing local definitions when other branches end in express…
f95c8d9 
…ions (#5323)

Summary:
A trailing expression in a `for` body can hide an uninitialized local when the iterable is empty. For example, `for x in xs: y = x; time.sleep(1)` can leave `y` undefined, but the expression incorrectly supplies termination evidence for the zero-iteration path.

Only count termination keys from branches that lack the variable. This also reports skipped `elif` walrus assignments and preserves the definite-uninitialized status of deleted exception targets.

This changes the default-enabled `unbound-name` diagnostic. It is independent of the attribute initialization check in #4326.

Validation:

- 479 tests passed across scope, loops, branching, and returns.
- Formatting and lint checks passed. Clippy reports existing warnings in unchanged code.

@asukaminato0721 I think this looks good! Thanks for working on it, and I appreciate you splitting up the diff and continuing to investigate. This was a big one!

I think the current failing tests are due to trunk health, so I'll rebase and fix internally

It looks like Conner is shepherding the internal diff, so I'm going to transfer the PR review :)
