- Session-per-model: each project keeps separate sessions per model per role
(haiku/sonnet/opus for DEV, grok for QA) instead of switching models
- Plugin-controlled lifecycle: sessions managed via Gateway RPC (sessions.patch)
and CLI (openclaw agent), not agent instructions
- New end-to-end flow diagram: human → Telegram → main session → plugin → gateway → sub-agent
- Session reuse diagram showing spawn vs send path
- Updated system overview with Gateway as explicit component
- Updated data flow map with new projects.json sessions schema
- Session spawn/send moved to "DevClaw controls" in scope boundaries
- Added session_health using sessions.list gateway RPC
- Added session transcripts to file locations table
