Announcing: wifi-densepose 2.0 Python SOTA extras — AETHER, MERIDIAN, MAT (PR #1387)

[ruvnet]

A compiled, PyO3-bound wifi-densepose pip package for passive WiFi-CSI sensing now ships three opt-in SOTA extras, each proven bit-identical to the native Rust core via a SHA-256 parity harness.

What landed

• AETHER — 128-dim contrastive CSI embeddings for room fingerprinting / re-identification, now with an optional trained-weight loader. pip install wifi-densepose[aether]
• MERIDIAN — hardware-invariant CSI normalization (ESP32/Intel/Atheros), AP-geometry encoding, few-shot LoRA room calibration. pip install wifi-densepose[meridian]
• MAT — CSI-based disaster-survivor detection with START-protocol triage. pip install wifi-densepose[mat]
• A real production bug fixed along the way: same-second training runs were silently overwriting each other's model files (.rvf filename collision) — found via CI, root-caused, fixed, and pinned with a regression test.
• pip-release CI's root failure (stale, 403-ing PyPI token) diagnosed and fixed. A premature migration to PyPI OIDC Trusted Publishing was caught by a pre-existing regression guard and correctly reverted.
• The dashboard's "Start Training" button — previously a silent no-op — now drives a real trainer with live /ws/train/progress streaming.
• archive/v1 formally deprecated with honest model-weight labeling.
• python/ is now gated in a real, blocking CI workflow instead of only being checked at release time.

Numbers

Default wheel	279 KB
[sota] combined wheel	2.2 MB (budget: ≤5 MB)
Tests passing	218
Parity fixtures	6/6 (binding == native Rust, SHA-256 gated)
Python support	3.10–3.13, one abi3 wheel per platform

What's still open — stated plainly

• Live PyPI publish is blocked on registering a PyPI Trusted Publisher — a one-time, account-holder-only step on pypi.org.
• SOTA accuracy validation: the parity harness proves the Python bindings are bit-identical to the native Rust code. It does not prove the native code hits its published accuracy bars against real labeled CSI — that needs a labeled dataset and eval harness that don't exist yet.
