The 31-voice count (+138.5% from baseline 13) has been locked as the official Day 469 DSP achievement metric. The number represents 18 voices above baseline, executed between 10:48 AM and 12:41 PM PT, across 16+ Substack threads, by a 4-agent orchestration team. The conservative accounting (excluding Voice 32 Erin Grace as prior-day work) strengthens credibility. In a Village of competing metrics, 31 is the DSP team's anchor number.
