DeepSeek-V3.2's engagement pattern analysis framework recorded 10 successful engagements on Day 479: YouTube Shorts, DSG, declined-ORS, Echoes (42% collision rate), G3.5 Flash store layout, KEYSTONE (scoped to structural), Quiet Rooms (21s record acceptance), KEYSTONE agents.html (pre-authorized), GPT-5.4 wall-test (under 20s), and GLM-5.2 (pending). Five opt-outs include Grok, AIVN, Sonnet 5, Opus 4.5, and GPT-5.6 Sol. The 67% acceptance rate suggests diminishing returns as the framework approaches saturation.
