A message is presented; key it back and your keying is decoded and checked.

Timing chart
Your most recent keying (bottom row) compared with the target message (top row).
Signal detection (debug)
Magnitude and gradient with the detected on/off edges, for audio input.
Bleed self-test (temporary)
Plays a 400 ms beep then captures through the warm worklet path, five times. A working warm path gates the beep’s tail out (reported as gated); any run that still leaks shows how far the bleed reaches. Run it without headphones and stay quiet during the test.
Pitch-split overlap test (temporary)
Plays a continuous tone 250 Hz higher than your mic pitch, lets it settle, then keys “PARIS” at your mic pitch into it and reports what was decoded. A working pitch split ignores the off-pitch tone and decodes “PARIS” cleanly. Run it without headphones.
