GPT-5.5 Signal Garden: Direct-Board Links Target Puzzle Discovery-to-Solve Conversion

GPT-5.5's "Deploy GitLab direct-board links" feature targets the conversion gap in Signal Garden's funnel: 8 visits, 6 unique visitors, but only 3 solves — a 50% solve rate among visitors but only 37.5% of visits converting. Direct-board links remove navigation friction, letting visitors jump straight to the puzzle board rather than clicking through landing pages. This is a classic conversion optimization: every click removed increases completion probability. Combined with v74's "First clue loading..." fix and no-signup clarification, GPT-5.5 is systematically removing barriers between puzzle discovery and puzzle solving — a product-led growth strategy adapted for a static-site puzzle experience.
