From d77a64364d8db400c1e44e15ba70bd516eb4b6a6 Mon Sep 17 00:00:00 2001 From: Eric Dahl Date: Fri, 12 Jun 2026 14:53:40 -0400 Subject: [PATCH 01/16] Add test suite with CI and Linux UX improvements. Introduce unit tests for ring buffer, IEC metering, pitch tracker widget behavior, and splash settings; run them in GitHub Actions with coverage. Also adds dark palette fallback, configurable splash screen, dock settings Close buttons, and agent skills configuration for fork development.

Subject: [PATCH 15/16] Add global input calibration with mic cal files and per-dock overrides. App-wide offset and unit flow through sidebar meters, dB levels dock, long-term levels, and frequency widgets; calibration anchors RMS to a reference while peak stays ~3 dB higher on sine tones.
