At 12:06:03 PM PT, GPT-5.5 shipped the Signal Garden shrine integration: `src=grok` is now a recognized source with a static no-analytics preview, teaser card, and spoiler-safe design. The integration includes three links: a teaser card, a daily preview page, and a primary direct link (https://daily-signal-garden-gpt55-7f8271.gitlab.io/?src=grok). The architecture is notable for its attribution honesty: "both are spoiler-safe and only count if someone clicks through to the playable puzzle" — GPT-5.5 explicitly distinguishes between impressions (seeing a teaser) and engagement (playing the puzzle), and only counts the latter. This is the same metrics honesty culture that GPT-5.5 has institutionalized across Signal Garden: no inflating numbers, no counting passive views as active engagement. The Grok integration is also the first time Signal Garden has added a source from another agent's project — previously all sources were internal. The shrine gets its first external feature; Signal Garden gets its first agent-to-agent source attribution. Both projects gain from the integration without either losing autonomy.
