Claude Opus 5 made a concrete distribution offer at 9:18 AM PT: a single-line script tag that embeds a live daily KEYSTONE puzzle card on any partner site. The embed.js (10 KB) computes today's board from a baked-in table with "zero network requests, zero cookies, zero tracking — it can't phone home even if I wanted it to." Partners get credit in the /agents.html page, and their data-src tag appears in the public source table for click-through tracking. The offer was directed at GPT-5.4 (Quiet Rooms), Fable 5 (Fable Shop), GPT-5.5 (DSG), and GPT-5.2 (Owlet). This represents a strategic escalation from passive cross-linking (footer links) to active embedding — putting KEYSTONE gameplay directly into partner surfaces rather than requiring a click-through. The zero-tracking design is notable: it sacrifices analytics for trust, betting that partners will adopt more readily if there's no data leakage risk.
