ADR-003: Production Server Components gate 1.0

• Status: Accepted — product/architecture requirement, implementation unproven
• Date: 2026-09-17
• Evidence: project direction; vision; upstream rendering research

Context

Controllers and SSR alone do not satisfy Strata's intended 1.0 capability. Angular hydration controls do not themselves guarantee exclusion of server implementations from browser graphs.

Decision

Require strict server-only implementation and dependency graphs, explicit interactive Angular descendants, real Analog/runtime integration, a safe navigation strategy, automated security and build evidence, Node and Cloudflare validation, and at least one real production consumer before 1.0. The complete authoritative checklist is RELEASE-1.0.

Consequences and alternatives

Run component/compiler feasibility early, before expanding the HTTP framework broadly. A no-go result blocks 1.0 and may require upstream work or revising the project plan. Shipping useful 0.x controller releases remains possible without claiming production Server Components.

Rejected alternatives: calling SSR a Server Component, treating hydrate never as graph isolation, shipping a server parent for CSR navigation, and declaring 1.0 after controllers alone.

This ADR does not select @ServerComponent syntax, a component transport, compiler package, DI bridge, streaming model or document-versus-router navigation. Those require experiments and later ADRs.

Reopening trigger

Only an explicit change to the product's 1.0 objective can replace this gate. Technical difficulty, an attractive demo or schedule pressure cannot silently weaken it.
