Extend test_client.py with async stats/usage/metrics + async events
stream, SSE edge cases (multi-line data, keepalive-only, incomplete
trailing frame, full payload round trip, 4xx → typed error), default
arg paths that omit query params, string/partial date variants, and
404/401 error paths. Verify __version__ == "0.3.0" and that the new
models (Actor, CapsuleMetrics, CapsuleStats, MetricPoint, Resource,
SSEEvent, UsageResponse) are exported from wrenn.models.
Add live integration tests in test_integration.py: TestStatsUsageMetrics
(stats default/range, usage no-args/date-range, metrics on a running
capsule, metrics range=2h, metrics on a destroyed capsule → 404) and
TestEventsStream (spawn reader thread, create capsule, assert its
lifecycle event arrives).
Add direct unit tests in test_code_runner_unit.py for the bare
_protocol helpers (pick_kernel_id, validate_language, build_ws_url,
apply_kernel_message) covering parent filtering, stdout/stderr
routing, execute_result vs display_data main flag, error emit, and
idle/busy status return.
Fix EventsResource.stream() and AsyncEventsResource.stream(): calling
_raise_for_status on a streaming httpx.Response without first reading
the body raised httpx.ResponseNotRead on any 4xx/5xx. Now read the
body (resp.read() / await resp.aread()) before status parsing when
status >= 400.
Bypass TestCodeRunnerMimeTypes._run in test_requests_status_code so
the in-capsule SSL/network failure skips the test instead of tripping
the helper's "unexpected error" pre-assertion.

- Rename `wrenn.code_interpreter` → `wrenn.code_runner` (canonical).
Keep old path as deprecation alias that emits a FutureWarning on
import, mirroring the existing `Sandbox` → `Capsule` pattern.
Submodule shims `code_interpreter/{capsule,async_capsule,models}.py`
keep direct-submodule imports working.
- Fix sync/async ctor-failure-safe `__del__`: initialise `_kernel_id`,
`_kernel_name`, `_proxy_client` before calling `super().__init__` so
a failed creation no longer crashes the destructor with
AttributeError.
- Send the kernel name to Jupyter. Previously `POST /api/kernels` had
no body, so the server picked an arbitrary default kernelspec. Now
sends `{"name": "wrenn"}` (override via `Capsule(kernel=...)`) and
reuses an existing kernel only when its `name` matches.
- Preserve Jupyter `text/plain` verbatim in `Result.from_bundle`.
The previous outer-quote strip was lossy (the string `'2'` became
indistinguishable from the int `2`, and strings containing escaped
quotes were mangled). `text` is now the `repr()` Jupyter sends.
Updated the stale `test_capsule_features` quote-strip test.
- Validate `run_code(language=...)`. Anything other than `"python"`
now raises `ValueError` instead of being silently ignored.
- Async `__del__` no longer touches the event loop; users must call
`await close()` or use `async with`.
- New unit suite `tests/test_code_runner_unit.py` (46 tests): MIME
unpacking, deprecation alias + warning, default template + kernel,
custom kernel override, ctor-failure-safe __del__, kernel
create/reuse/cache, retry on 5xx, 4xx propagation, request shape,
run_code stream/result/error/foreign-parent/idle/unsupported-language,
async variants.
- New e2e suite `tests/test_code_runner_e2e.py` (44 tests, integration
marker): template == `code-runner-beta`, kernel == `wrenn`, stdout
/stderr capture, state/import/function/class persistence, exceptions
(Value/Name/Syntax), callbacks, multi-line, `text` repr preservation,
filesystem round-trip, isolation between capsules, deprecated import
path. MIME-type class covers html, markdown, json, latex, svg,
javascript, png (matplotlib + seaborn), jpeg, multi-format bundles,
and text-round-trip via numpy + requests.
- `make test-code-runner` runs unit + e2e together. `make test`
extended to include the unit file.
- README: "Code Interpreter" section renamed to "Code Runner", all
imports updated, `kernel=` documented, removed the incorrect
"quotes stripped automatically" claim, replaced with the actual
`text/plain` semantics.
- CLAUDE.md: appended a "Code Runner Module" section covering module
path, defaults, kernel-reuse semantics, lifecycle invariant, and
the new test files + make target.
