Responsibility boundaries¶

foundation.web owns shared Web baseline semantics: browser identity/favicon declaration, generalized canonical navigation and accessibility expectations, plus viewports and input capabilities.

artifact.webapp-core owns application semantics: application surfaces, task/action-oriented UI states, authentication and access-failure behavior, and the binding of those behaviors to shared route IDs. Each Webapp application-route behavior target is browser-sensitive and therefore requires positive and negative browser-backed executable proof using an authoritative command whose execution capabilities include browser. Its validator is authoritative for Webapp-specific evidence targets; the shared foundation remains product-neutral.

capability.pwa owns its installability, application-icon, offline/freshness, and update proof families. Selecting PWA does not transfer those proof families to either foundation.web or artifact.webapp-core.
