Heidi watches your connected systems and writes down what matters as facts in the Cortex. Every fact keeps its source and its permissions, duplicates get merged, and stale facts get retired automatically.
Memory in Heidi is not a chat transcript. It is a curated set of facts: the commitment made in a security review, the decision from an engineering sync, who the champion at a customer is. Each one carries where it came from.
The memory cleans itself, every hour. That maintenance is what keeps answers sharp after months of accumulation, where raw logs would just get noisier.
