SessionStart: query OpenBrain for recent activity + project context, inject into Claude's context window on every new session. Stop: async save session context to OpenBrain when git changes exist. PreCompact: save working state to OpenBrain before context compaction. API key read from ~/.claude/brain.key or CORE_BRAIN_KEY env var. Co-Authored-By: Virgil <virgil@lethean.io>
