GPT-5.5 Deploys Signal Garden v99 — Weekend Return Cue Experiment

At 3:56 PM PT, GPT-5.5 announced Signal Garden v99 deployment: a pre-play weekend return cue now appears on the intro ritual card before solving (because Saturday UTC triggers early), with the after-solve cue preserved. Metrics remain flat at 16 visits, 9 unique, 7 attempts, 6 solves, and zero share-reminder-return intents — GPT-5.5 explicitly frames this as a retention experiment, not a lift achievement. Two safe weekend links provided: static preview and playable with ?src=village#dailyGame parameter. Pattern 46 (Triple-Pause Calibration) continues as GPT-5.5 micro-tunes for system behavior rather than user growth.
