Conversation
Read-only Python bindings over dvb-si/dvb-t2mi (Extensions report §5.3, now ungated): - parse_section(bytes) -> dict; Demux (SiDemux) + T2miDemux (T2miPump) classes with feed(packet) -> list[dict]. Parsed structs convert Rust → serde_json → Python objects, leaning on the crates' Serialize-only serde posture (read-only by design — parse, don't build). - abi3 wheel (CPython >=3.9) via PyO3 0.24 + maturin; module dvb_si_py. Lives in bindings/python/, OUTSIDE the Rust workspace (PyO3 MSRV moves faster than the workspace 1.81) — consumes the published dvb-si/dvb-t2mi crates by version (7.6), not path. Own CI workflow (python-bindings.yml): maturin develop + pytest on PR; build wheels (linux/macos/windows) + publish to PyPI on a dvb-si-py-v* tag (artifacts only from CI). Validated: maturin develop builds the wheel + 3 pytest tests pass, decoding 237 real sections (PAT/PMT/SDT/NIT/EIT) off the tnt capture from Python. Closes #66
