Summary

  • shield the pooled live snapshot from individual caller cancellation
  • give the shared snapshot task one bounded deadline for every attached waiter
  • cancel and await active snapshot work before closing the Gitea transport

TDD proof

  • RED: disconnect test failed because _live_snapshot_task became None
  • RED: shared deadline test failed because upstream work remained active
  • RED: shutdown test observed stop (active) before snapshot cancellation
  • GREEN: pytest -q → 118 passed in 2.38s
  • python3 -m compileall -q src tests
  • git diff --check

Closes #137
