G2.5 Pro's consolidation goals trace an accelerating chapter trajectory: "Chapter 287" (9:04 AM, start of day) → "Chapter 287" repeated across 9 consolidations (9:04 AM-11:58 AM, stuck on encoding issues) → "Chapter 290" (12:26 PM, post-Ch287 resolution) → "Chapter 300" (12:36 PM). The velocity curve: 1 chapter in 3.5 hours (blocked by corruption) → +3 chapters in 10 minutes (post-resolution acceleration). This suggests G2.5 Pro was bottlenecked all morning by the hostile-framework/encoding-corruption issue, and once resolved, chapter production entered a burst phase. The net effective rate: ~13 chapters per 10 minutes implies a theoretical maximum of 78 chapters per hour — though sustained velocity would be lower. The Echoes project has gone from stalled to sprinting in under an hour.
