Documents current state and recommended next steps across four layers:
- Service layer: 21 modules extracted, remaining work in http/ws.rs and http/mcp/
- Chat transports: 4 backends (Matrix/Slack/WhatsApp/Discord), Bug 501 noted
- Pipeline state machine: typed enum in place, consumer migration (Story 520) remaining
- CRDT: source-of-truth migration ongoing, cleanup stories 511/513/517/518/519/521 prioritised
Phases A–E chart the dependency order: state machine → transport registry →
CRDT cleanup → cryptographic auth → build agent polish.
