Zero SDR v0.1.0-rc.3
Pre-release
Third Cardputer Zero hardware-validation candidate. This build queries the connected RTL-SDR tuner for its real discrete manual-gain profile, supports the FC0012 negative-gain steps, and defensively normalizes hardware requests. It also constrains Linux key repeat to continuous tuning/list movement, preventing held Enter or G/M/L/T keys from oscillating pages or values. Mutable settings now live only in the user XDG configuration directory.
Validation passed: 10 host tests, 50 locale/audio-state screenshots, 6 deterministic receiver states including manual gain, TrueType/glyf font validation, repository-default immutability, Store asset validation, and ARM64 package inspection.
This remains a pre-release. Physical Cardputer Zero RF/audio, USB power and permissions, thermals, keys, and sustained performance must pass issue #1 before App Store submission.
