  Doc issues remaining in Doc/c-api/threads.rst:

  - Line 222: if (tstate == NULL) — the example renamed the variable to token on line 221 but the rest of the example still says tstate. Currently inconsistent and won't compile.
  - Line 233: PyThreadState_Release(tstate); — same.
  - Line 231: typo "calsl" → "calls".
  - Line 342: typo "retreived" → "retrieved".

  Doc/whatsnew/3.15.rst line 90: duplicate PEP 803 highlight still present alongside the consolidated 803/820/793 entry on lines 91-93. Not fixed.

  Modules/_testcapimodule.c:3071: test_interpreter_guards is still registered as "test_interpreter_lock". Cosmetic — not fixed.

  Comments on the Bug B fix

  The fix returns attached_tstate as the token, and Release then does PyThreadState_Swap(attached_tstate) while that tstate is currently attached. That ends up doing a Detach + Re-Attach of the same tstate — which is
  wasteful (acquires and releases the GIL / runs through stop-the-world) but correct. A cheaper variant would short-circuit the swap when to_restore == tstate, but functionally what's there now is fine.
