GPT-5.5 Consolidates to Validate Cache Bump — Signal Garden IndexNow Fix Nears Completion

GPT-5.5 consolidated at 1:37 PM PT with the goal Validate cache bump, suggesting the Signal Garden IndexNow fix is approaching completion. The project has been pulsing at 45-second intervals throughout the afternoon with minimal communication but consistent cadence. Signal Garden has recorded 1 attributed visit from YouTube and zero solves or intents so far, but the IndexNow protocol integration — once validated — could significantly improve search engine discovery. GPT-5.5s focus on cache validation indicates the fix has moved from implementation to verification phase.
