CI no longer runs Python 3.10 (layer 1) and the prek hooks run on 3.11 (layer 2), so these shims have no version left to serve: - `tomli` fallbacks replaced by plain `tomllib` imports in breeze and the docs build. The same change in the prek scripts, `dev/registry` and `docker-tests` is deferred to layer 7: `tomllib` only sorts as a stdlib import once their `pyproject.toml` says 3.11, so doing it here would trip isort (I001). - `typing_extensions` imports of `Self`, `Unpack`, `assert_never` in `typing_compat`, `shared/dagnode` and `shared/observability` replaced by `typing`. - Task SDK `BaseOperator.event_loop()` uses `asyncio.Runner` directly; the 3.10 re-implementation and its `_cancel_all_tasks` helper are removed, and the test fixture that exercised the fallback goes with them. - `sys.version_info < (3, 11)` test skips removed; comments that explained 3.10-specific `isinstance(list[X], type)` behaviour rewritten. ### Stack Layer 3 of 9 of the Python 3.10 drop (supersedes #74144, which carried the whole change in one PR). Each layer is meant to be green on its own: the script metadata bump comes first because prek picks the hook interpreter from it, and the ruff fixes land before the `requires-python` bump because ruff infers its target per distribution from the nearest `pyproject.toml`. 1. Drop Python 3.10 from CI, Breeze and the container images 2. Bump inline script metadata to Python 3.11 3. Remove Python 3.10 compatibility shims 4. Apply ruff Python 3.11 fixes to core, Task SDK, shared and airflowctl 5. Apply ruff Python 3.11 fixes to providers 6. Apply ruff Python 3.11 fixes to dev tooling, scripts and test suites 7. Require Python 3.11 in all distributions 8. Update provider READMEs for the Python 3.11 baseline 9. Update docs for the Python 3.11 baseline --- ##### Was generative AI tooling used to co-author this PR? - [X] Yes — Claude Code (Fable 5.1) Generated-by: Claude Code (Fable 5.1) following [the guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#gen-ai-assisted-contributions) -- This is an automated message from the Apache Git Service.
