Introduction
Tessera Agent's final Generative UI architecture, proven first through governed data-agent workflows.
Tessera Agent is the product documented in this site. The current repository is its complete Generative UI architecture and proof ground: the protocol, compiler, runtime, authority boundary, client controller, React surface, data components, fixtures, and evaluation gates all live here until the data-agent experience is proven end to end.
The framework-neutral packages use the @open-generative/* namespace because
that is the future extraction boundary. It is not a second product in this
repository and it does not change the current acceptance target. A standalone
Open Generative project is created only after Tessera Agent passes every proof
gate.
One render chain
trusted SurfaceEventStream
-> SurfaceController
-> GenerativeSurface
-> exact RendererRegistryThe model proposes declarative nodes. It never emits JSX, HTML, CSS, SQL, tool names, credentials, or executable formulas. The Host owns data, identity, validation, authority, state, effects, persistence, commit, and rendering.
Current scope
The public UI catalog is intentionally focused: five analytical composition
Contracts plus one governed data.chart Contract with 17 named recipes. Each
recipe has its own information structure and visual treatment while sharing the
same trusted resource, validation, and rendering chain.
Generative UI architecture
Read the single protocol, authority, commit, and rendering design.
Data-agent proof gates
See the deterministic, security, rendering, and product-quality gates Tessera Agent must pass.
Data charts
Inspect all 17 chart recipes through the live verified renderer.
Agent architecture
Connect the Generative UI system to governed analysis, evidence, and production operation.
