Description of the change

A sufficiently large positive or negative integer in report_message(..., extra_data=...) causes the default, unbatched serializer to replace the entire custom context dictionary with "<class 'dict'>", losing neighboring fields too.

Return integers directly before the floating-point NaN/infinity checks. Python can JSON-encode these integers; converting them to float for math.isnan/math.isinf raises OverflowError. Preserve existing finite-float and non-finite labels.

Validation

• Before: 4 failed, 16 passed new cases. Failures cover positive/negative integers through both the transform and public report_message API. Batched-mode, ordinary numeric, boolean, NaN and infinity cases provide controls.
• After: 57 relevant transformation/report-context tests passed.
• Base test dependency suite: 328 passed, 85 skipped.
• After installing the declared optional type/framework dependencies: 416 passed, 1 skipped, 3 failed (plus 10 subtests passed). Unchanged upstream with the new tests excluded produces 396 passed, 1 skipped, the same 3 failures: two threaded async-handler tests and test_report_exception_with_same_exception_as_cause, involving request-context state. Those baseline failures are not fixed here.
• MyPy: success, 52 source files.
• New test file passes Flake8. Changed production file retains two baseline Flake8 diagnostics (E301 at line 15, C901 on transform_custom); verified against unchanged upstream. No new diagnostic introduced.
• git diff --check passes. Python 3.12; no full Python/framework version matrix run.
• All reports use mocked transport. No hosted Rollbar account, real access token, events, paid resources, or UI automation.

Checklists

• New tests cover the fix.
• Relevant tests pass locally.
• Full lint/suite green: baseline limitations documented above.
• Human review / reviewer assignment pending.
