A bounded self-analysing drone with non-zero-base colour and a short crossfade is the safe Punctual recovery program

When a Punctual program fails to parse or the canvas blooms or blacks out, the canonical recovery is to evaluate a known-safe minimal program. The recommended fallback: a two-oscillator drone (osc 55 + osc 82.5 >> audio) for bounded audio, plus [0.15 + 0.5*lo, 0.10 + 0.4*mid, 0.20 + 0.4*hi] >> rgb <> 2 for colour that tracks the program’s own spectrum with non-zero base terms so the frame reads intentional even in near-silence. The <> 2 crossfade makes the recovery smooth. Every statement is routed, no feedback can run away, and lo/mid/hi have an audio source to analyse.

Examples

When the canvas blooms to white, evaluate the panic fallback — within 2 seconds the screen transitions to a calm drone-reactive colour field.

Assessment

Write a minimal, always-valid Punctual recovery program from memory, and for each line explain which class of silent or thrown failure it avoids.
