A minimal ChucK panic patch uses SinOsc-to-dac with a timed while-loop and no sample files

When a ChucK program errors or collapses during performance, the recovery procedure is to replace the running shred with a minimal, always-valid patch that addresses the common silent-failure modes at once: a clear path to dac (avoids the no-audio-path bug), a while(true) loop that advances time (avoids the infinite-silent-loop bug), synthesis-only with no sample files (avoids sample-not-found), and low gain (avoids clipping). The canonical minimal patch is a SinOsc or SawOsc into a filter into dac, looping with a 20::ms => now advance. In chuck --loop, deliver it with Machine.replace(id, "panic.ck").

Examples

SinOsc s => dac; 0.15 => s.gain; 110 => s.freq;
while(true) 1::second => now;

Assessment

Write a ChucK panic patch that guarantees a clear dac path, an advancing time loop, no sample dependency, and safe gain, and name the recovery command to swap it into a running VM.
