A minimal groove using only bundled synths and samples with a sleep in every loop is the safe Sonic Pi recovery

When a Sonic Pi run errors or the mix collapses, the canonical autonomous recovery is a minimal groove using only built-in resources that avoids every common failure at once: :bd_haus and :saw are bundled synths/samples (so nothing needs loading), every loop has a sleep (so no did-not-sleep error), use_bpm is set once at the top (so sleep-beats are sane), and the bass uses sync: :kick which is auto-satisfied because :kick is a live_loop (no sync deadlock). The recovery pattern leaves no silence while rebuilding.

Examples

After a run error, evaluate the panic fallback: use_bpm 120; live_loop :kick do; sample :bd_haus; sleep 1; end; live_loop :bass, sync: :kick do; use_synth :saw; play :e1; sleep 0.5; end.

Assessment

Write a minimal, always-valid Sonic Pi recovery groove from memory, and for each live_loop identify the class of failure its structure prevents.
