ADR-117 P1 — the python/ directory is now a working maturin-buildable
crate that produces the v2.x replacement for the legacy pure-Python
wifi-densepose==1.1.0 PyPI wheel.
## What lands
- `python/Cargo.toml` — PyO3 0.22 with `extension-module` + `abi3-py310`
(one binary covers Python 3.10–3.13 per OS/arch — keeps the
cibuildwheel matrix to 5 wheels per release, not 20). Depends on
`wifi-densepose-core` from the existing v2/ workspace via relative
path.
- `python/pyproject.toml` — maturin>=1.7 build backend with
`python-source = "python"` and `module-name = "wifi_densepose._native"`
so the compiled module loads as an internal underscore-private
submodule of the user-facing `wifi_densepose` package. PEP 621
metadata + classifiers + project URLs. Optional-deps:
`wifi-densepose[client]` for the P4 WS/MQTT pure-Python layer,
`wifi-densepose[dev]` for the test toolchain (pytest, ruff, mypy).
- `python/src/lib.rs` — minimal `#[pymodule] wifi_densepose_native`
exporting `__rust_version__`, `__rust_build_tag__`,
`__build_features__`, and a `hello()` smoke function. P2 will land
the core type bindings here.
- `python/wifi_densepose/__init__.py` — pure-Python facade re-exporting
the compiled module's symbols under their stable user-facing names.
Docstring teaches the v1→v2 migration story up-front.
- `python/wifi_densepose/py.typed` — PEP 561 marker so `mypy --strict`
in user code treats the wheel as fully typed (real stubs land in P2).
- `python/tests/test_smoke.py` — 6 P1 acceptance tests:
1. package imports without error
2. version string is PEP 440-compliant
3. `__rust_version__` is reachable from Python (the diagnostic
surface ADR-117 §5.2 promised)
4. `__build_features__` lists `p1-scaffold` marker
5. `wifi_densepose.hello()` returns "ok" (FFI round-trip)
6. `wifi_densepose._native` is reachable but the leading underscore
conveys "private; users should import the parent package"
- `python/README.md` — phase ledger, local build instructions
(`maturin develop`), layout diagram.
## What's deferred to P2+
- Core type bindings (`CsiFrame`, `Keypoint`, `PoseEstimate`) — P2
- Vitals + signal DSP bindings + witness v2 — P3
- Pure-Python WS/MQTT client layer (`wifi_densepose[client]`) — P4
- cibuildwheel + PyPI publish — P5
- v1.99.0 tombstone — concurrent with P5
The new `python/` crate is intentionally OUTSIDE the v2/ Cargo
workspace — it has its own Cargo.toml with `[package]` not
`[workspace.package]` inheritance — to keep maturin's `python-source`
+ `module-name` config self-contained and to avoid forcing every
`cargo test --workspace` invocation in v2/ to compile pyo3.
