Description of the change

Empty built-in tuples share an identity. Memoizing that identity made later empty logging argument tuples become CircularReference strings instead of empty JSON arrays. Skip memoizing only empty built-in tuples, while still invoking their handlers at each occurrence. Non-empty tuples and recursive containers retain the existing reference handling.

Fixes #402.

Type of change

• Bug fix (non-breaking change that fixes an issue)

Validation

• Three regression subcases fail before the fix and pass afterward; both traversal orders and batched/unbatched serialization are covered.
• A tuple containing a recursive list still receives the circular-reference label.
• 44 focused tests and 4 subtests pass.
• Full base suite: 309 passed, 85 skipped, one Windows-only /tmp versus \tmp path assertion failed. The same failure was reproduced with the original traversal implementation. Optional framework integration suites were not run.
• mypy: no issues in 52 source files; git diff --check passes.

Checklists

• Changed behavior is covered with tests.
• All tests related to the changed code pass.
• Descriptive title and review context provided.
• Changes reviewed by another engineer.
