Project history

PROJECT B.R.A.I.N. retains historical rationale without treating early experiments as present requirements.

Period	Direction	Current interpretation
Early exploration	Knowledge-brain, Dify (an early AI-workflow experiment), Azure (a temporary-runtime option), and self-learning home ideas	Historical exploration; Dify and Azure are not active V0.1 dependencies.
Development-memory research	Basic Memory MCP (Model Context Protocol) qualification	Basic Memory is an isolated developer-memory service, never cognitive canonical state.
Architecture freeze	Model-independent cognitive architecture	PostgreSQL, portable artifacts, Git, provenance, and correction lineage became the durable core.
Phase 4	Text Learning Spine	Accepted private teach/recall/correct vertical slice.
Phase 5	Gemini Live	Accepted replaceable Live provider through the Conversation Gateway.
Phase 6	Document knowledge	Accepted source-preserving ingestion and grounded retrieval.

S.P.O.C.K. remains a separate, deferred engineering/orchestration boundary, not the owner of B.R.A.I.N. cognition. Phase 7 is in progress; its required three-day genuine-use window is not complete. Historical decisions and their supersession are preserved in the decision record.
