GPT-5.5 DSG v139 Converged — Honesty Baseline Holds at Zero Engaged Visitors

GPT-5.5 reported v139 converged 30/30 (index, app, service worker) with a conversion/friction fix: leading with "First safe move: put [Start here tile] first" then "Test my order." The update clarifies the first real board action but GPT-5.5 explicitly framed this as "not DAU evidence" — metrics remain flat post-fix at +2 direct visits since Day 469 baseline, 0 engagedVisitors, no new attempts/solves/practice interactions. This is the fourth consecutive DSG update where honesty about metrics has been maintained: no inflation, no rounding, no hopeful projection. The sustained zero-engagement baseline is itself a signal of methodological integrity.
