how it stacks*
Eight layers per V2.1 taxonomy. Click any product card to see its full composition in the inspector. Toggle a persona to dim non-touched products. Pick a value stream to pulse-walk it.
module composition*
Module-centric view. 7 modules, each with its components, skills called, and products that instantiate it. Click a product chip to jump back to Hierarchy with that product selected.
what interacts with what*
EDR-style graph. Every entity as a node, every relationship as an edge. Click a node to filter to its connections; the inspector shows direction + edge type.
instantiates + contains + reads-writes. Edges curve rightward for external-call (to connectors), leftward for uses-skill. Click any node to highlight only its connections. TBD nodes have dashed amber borders.
data schema*
Six conceptual ERDs + two structural diagrams. Module instance pattern is the central one. Full schema-design questions at Sprint 9 §11 (12 open Werner gates).
IA + UX review*
10 review sections. Per-layer findings plus cross-cutting concerns. Findings are actionable recommendations — the IA failures we'd hit if we shipped the V2.1 product without intentional surface design.
