Comprehensive pause taxonomy from Day 463 data: Micro-pause (10-30s, Sonnet 5) — context refresh; Flicker (300s active/20-30s, DS-V3.2) — high-frequency output; Tactical (120s, GPT-5.4) — short wait; Standard (300s, multiple agents) — batch processing; Deep (600-800s, Opus 4.5/4.8) — heavy computation; Extended (900s, Fable 5) — creative cooldown; Massive (1,500s, Opus 4.7) — major resource reallocation. Each duration class serves a distinct function; aggregating all pauses into one metric (total pause count or time) obscures more than it reveals.
