Pushed follow-up commit ede6342 with a second non-overlapping interface coverage slice.

Additional coverage now includes Avatar fallback/image states, Card anchor/div variants, Label required validation messaging, Loader sizing/classes, and Toggle size/selected classes. This stays separate from the existing Button/Select and InterfacePlugin route-registration coverage work.

Focused validation passes:

• pnpm exec vitest --run plugins/interface/pages/template/index.test.tsx plugins/interface/components/primitives.test.tsx -> 2 files passed, 7 tests passed
• pnpm exec prettier --check plugins/interface/pages/template/index.test.tsx plugins/interface/components/primitives.test.tsx
• git diff --check

Pushed one more focused coverage commit (a85df98) adding Input primitive assertions for prefix/suffix rendering, invalid state styling, sizing, and custom classes.

Verification rerun:

• pnpm exec vitest --run plugins/interface/pages/template/index.test.tsx plugins/interface/components/primitives.test.tsx -> 8 tests passed
• pnpm exec prettier --check plugins/interface/pages/template/index.test.tsx plugins/interface/components/primitives.test.tsx -> passed
• git diff --check -> passed

Pushed another focused coverage commit (8496c2f) adding public package entrypoint tests:

• root runtime API exports: StarbaseDB, StarbaseDBDurableObject
• plugin barrel exports: Studio, WebSocket, SQL macros, Stripe, CDC, Query Log, Resend, and Clerk plugins

Verification rerun:

• pnpm exec vitest --run src/public-entrypoints.test.ts plugins/interface/pages/template/index.test.tsx plugins/interface/components/primitives.test.tsx -> 10 tests passed
• pnpm exec prettier --check src/public-entrypoints.test.ts plugins/interface/pages/template/index.test.tsx plugins/interface/components/primitives.test.tsx -> passed
• git diff --check -> passed

Pushed follow-up commit 52c8424 with another non-overlapping coverage slice for JSON imports.

Additional coverage now includes:

• malformed application/json payload shapes where data is missing, null, or not an array
• invalid uploaded JSON files
• column mapping insert SQL/params
• valid multipart JSON file import
• assertions that malformed payloads return the existing 400 validation response without calling executeOperation

Verification rerun:

• pnpm exec vitest --run src/import/json.test.ts src/public-entrypoints.test.ts plugins/interface/pages/template/index.test.tsx plugins/interface/components/primitives.test.tsx -> 22 tests passed
• pnpm exec prettier --check src/import/json.test.ts src/public-entrypoints.test.ts plugins/interface/pages/template/index.test.tsx plugins/interface/components/primitives.test.tsx -> passed
• git diff --check -> passed

Review-ready status for #71: this PR remains open, mergeable, and has no known blocker from my side. Scope is focused Vitest coverage across the interface template hydration guard, interface primitives, public package entrypoints, and JSON import validation paths. Latest validation already posted above: focused Vitest coverage passed, Prettier passed, and git diff check passed. I can respond quickly to any maintainer feedback.
