Changelog

v0.1.0 — first release

• Bridge (pip install hackrf-web): loopback WebSocket server in front of unmodified hackrfpy; per-launch token; --fake simulated board; --doctor; serves the page itself as a fallback to GitHub Pages.
• Session manager with idle / sweep / iq / tx states, one child process at a time, every transition through idle. Sweep rows stitched into frames; IQ blocks windowed, FFT'd and averaged in the bridge; frames at ≤ 12/s.
• IQ recording to interleaved int8 + SigMF sidecar through hackrfpy, with a mandatory time cap and a disk check; display blocks may drop, recorded bytes never do.
• Transmit (tx.tone) behind three gates: --allow-tx, confirm: true, a capped duration. The page shows the section locked with the reason.
• Page: Bridge / Sweep / IQ / Gains / Recording / Export / Transmit / Diagnostics / Settings / About; windows with Spectrum, Waterfall, IQ time and Constellation; markers with interpolated peaks, −3 dB bandwidth, band power, and "tune IQ to marker"; page-side max/min/average/hold.
• Demo replays spectrum frames computed from a real HackRF One recording (hackrfpy's fm_98.1MHz_8Msps.iq) and sweep frames from the fake device.
• CI: smoke test of the bridge on Linux and Windows; wheel built on push and attached to releases.
