+# Repository Map
+
+Central registry of all Flowmade repositories.
+
+## How to Use This
+
+Each repo's CLAUDE.md should reference this map for organization context. When working in any repo, Claude can check here to understand how it fits in the bigger picture.
+
+**Status markers:**
+- **Active** - Currently in use
+- **Splitting** - Being broken into smaller repos
+- **Planned** - Will be created (from split or new)
+
+## Repositories

+### Organization
+
+| Repo | Purpose | Status | Visibility |
+|------|---------|--------|------------|
+| architecture | Org source of truth: manifesto, Claude tooling, learnings | Active | Public |
+
+### Platform
+
+| Repo | Purpose | Status | Visibility |
+|------|---------|--------|------------|
+| arcadia | Monorepo containing platform code | Splitting | Private |
+| aether | Event sourcing runtime with bytecode VM | Planned (from Arcadia) | Private |
+| iris | WASM UI framework | Planned (from Arcadia) | Public |
+| eskit | ES primitives (aggregates, events, projections, NATS) | Planned (from Arcadia) | Public |
+| adl | Domain language compiler | Planned (from Arcadia) | Private |
+| studio | Visual process designer, EventStorming tools | Planned (from Arcadia) | Private |
+
+### Infrastructure
+

+
+## Relationships
+
+```
+arcadia (splitting into):
+├── eskit (standalone, foundational)
+├── iris (standalone)
+├── aether (imports eskit)
+├── adl (imports aether)
+└── studio (imports aether, iris, adl)
+
+gitserver (will use):
+├── eskit (event sourcing)
+└── iris (UI)

+
+## Open Source Strategy
+
+See [repo-conventions skill](skills/repo-conventions/SKILL.md) for classification criteria.
+
+**Open source** (public):
+- Generic libraries that benefit from community (eskit, iris)
+- Infrastructure tooling that builds awareness (gitserver)
+- Organization practices and tooling (architecture)
+
+**Proprietary** (private):
+- Core platform IP (aether VM, adl compiler)
+- Product features (studio)
