+# Phase 1.1: Hexagonal Architecture - Context
+
+**Gathered:** 2026-01-30
+**Status:** Ready for planning
+
+<vision>
+## How This Should Work
+
+Event bus is the backbone of the architecture. Modules communicate through events, not direct calls — server, process, logging all decoupled and talking through a central event system.
+
+This isn't just about clean code. It's preparing the nervous system for when agents exist. When you have multiple agents spawning, coordinating, merging work — those are all events flowing through the system. Get the pattern right now while it's simple.
+
+The CLI talks to the server through tRPC. Type-safe, clean contract. Same interface whether it's CLI or future WebUI.
+
+</vision>
+
+<essential>
+## What Must Be Nailed
+
+- **Extensible event bus** — In-process EventEmitter abstracted behind an interface. Must be swappable for external systems (RabbitMQ, Knative Eventing) later. Ports/adapters applied to the event infrastructure itself.
+- **Tests pass** — Everything from Phase 1 has test coverage. Can't refactor without a safety net.
+- **tRPC contract** — CLI-server communication pattern established with type safety.
+
+</essential>
+
+<specifics>
+## Specific Ideas
+
+- Start with Node EventEmitter, abstract behind an interface — simplest swap path to external event systems
+- Ports/adapters structure: `adapters/in.<name>/`, `adapters/out.<name>/`
+- Event dispatcher is itself a port — can swap implementations without touching core logic
+
+</specifics>
+
+<notes>
+## Additional Context
+
+This is a retrofit of Phase 1 code, not a greenfield build. The existing server, process management, and logging all need to be refactored to use the event bus pattern.
+
+Priority is establishing the extensible event pattern correctly — this is the foundation for multi-agent coordination in later phases.
