About

Mycorrhiza stores AI conversation memories in a local SQLite database using a SHA-256 blockchain-style hash chain structure. Each memory is cryptographically linked to the previous entry, making the chain tamper-evident. Three tools cover saving memories with tags, retrieving them by query or tag, and validating the chain's integrity. Data is stored in ~/.mycorrhiza/chain.db with an estimated 92 MB footprint per year.
