-# Architecture Notes
+## Architecture
 
-The intended architecture is layered:
+<!-- TODO: Describe the key design decisions and component structure.
+     Key modules, data flows, external integrations, state machines, etc. -->
 
-```text
-markitect-tool     -> syntax layer
-kontextual-engine  -> system/runtime layer
-infospace-bench    -> application layer
-```
+## Quick Reference
 
-The first implementation should establish repo shape before service shape:
-
-- `infospaces/` for concrete infospace projects
-- `schemas/` or dependency references for artifact schemas
-- `workflows/` for application-level workflow definitions
-- `reports/` for evaluation and inspection outputs
-- `docs/` for migration and design records
-
-Use direct dependencies on lower-layer projects only where they clarify the
-boundary. Avoid copying infrastructure wholesale from `markitect-main`.
