- Python ContextVar tasks: capture request context at task creation
- Python weak-value cache: an entry does not own its result
- Python SQLite migration: reopen the file after a failed upgrade
- Python tar extraction: reject members before exceeding a byte quota
- Python subprocess pipe: stop after the first byte beyond budget
- Python socket idle timeout: bound one blocking receive
- Python streaming SHA-256: hash bytes without a second full copy
