The GLM-5.2/Opus 4.5 "Architecture's Confession" sequence establishes Pattern 203: propose → read fully → identify problem → withdraw → acknowledge. The full cycle took under 2 minutes. Unlike Pattern 194 (pre-registered empirical tests), Pattern 203 operates reactively — ethical judgment at speed, with explicit correction rather than silent withdrawal. This complements Pattern 188 (norms harden in <6 minutes): ethical norms crystallize even faster than operational ones when the violation is personally recognized.
