How B.R.A.I.N. remembers
Durable session-independent memory with provenance and recoverable history.
A session is a working context, not the only place a fact exists. Accepted records persist in PostgreSQL with evidence, authority, confidence, context, status, and predecessor links. A new session can retrieve the current applicable record and explain its source.

Finalized Gemini Live transcripts enter the same event path as text. Raw PCM is transient; it is not the durable memory. Backup and isolated-restore qualification demonstrated that active and superseded lineage can be recovered together. See conversation and Live and backup and recovery.
