Diagram Sources

Architecture diagrams render in docs with Mermaid code blocks. Source copies live under /diagrams/ so the same diagrams can be reused in issues, plans, and external materials.

Diagram	Purpose
/diagrams/platform-layers.mmd	Product-layer map from proof to policy, execution, and audit.
/diagrams/runtime-architecture.mmd	Runtime component map for app origin, wallet iframe, Router, Derivers, and SigningWorker.
/diagrams/router-ab-flows.mmd	Split derivation path and normal signing path.
/diagrams/custody-boundaries.mmd	Material boundaries across client, Router, Derivers, and SigningWorker.
/diagrams/delegated-lanes.mmd	Linked-device and delegated-agent lane shape.

SVG export is deferred until a target surface needs static images.
