ARCHITECTURE.md covers the system design: exod backend, single Kotlin
desktop app (Obsidian-style), layered architecture, data flow, CAS blob
store, cross-pillar integration, and key design decisions.
PROJECT_PLAN.md defines six implementation phases from foundation through
remote access, with concrete deliverables per phase.
CLAUDE.md updated to reference both documents and reflect the single-app
UI decision with unified search.
