   Vue.js could plausibly be built, compiled, and tested headlessly in CI (e.g., via Vite/vue-cli/vitest pipelines), so the axis is a fair question for a JS framework, but the evidence pack contains no documentation, examples, or community reports of headless/CI automation usage — only general framework marketing and unrelated community opinions.

   Vue's docs claim a compiler-optimized, incrementally adoptable framework with official router/state tooling suited to scaling apps, and some community feedback (vue-comm-9) confirms official router/Vuex helps large-app cohesion. However, multiple hands-on developer reports directly contradict the 'scales well for large/complex apps' claim: 'Vue is good for simple things...does not shine for complex apps' (vue-comm-7), 'too magical...for really complex applications' (vue-comm-18), Vuex breaking modularity (vue-comm-19), and persistently weak TypeScript support for large codebases (vue-comm-3, vue-comm-15, vue-comm-17), which is a key maintainability concern at scale.

   Svelte's compiler-based approach is documented to produce efficient, minimal-JS output for fast apps (svelte-gh-1, svelte-docs-1), and real-world reports confirm performance/bundle-size wins after migrating a large, complex app (svelte-comm-8) plus 'snappy' feel with readable generated code (svelte-comm-5). However, other hands-on reports flag scaling pain points relevant to large codebases/teams: rendering performance issues appearing before interactivity limits (svelte-comm-10), unclear route/layout folder organization at scale (svelte-comm-4), sparse ecosystem forcing custom component work (svelte-comm-9), and gaps in testing docs/IDE support (svelte-comm-11, svelte-comm-15). Missing for 10: dedicated large-scale case studies, benchmarks on maintainability tooling (testing, type-safety at scale), and resolution of the ecosystem/testing gaps noted by users.

Streaming page loads

   weight 3 · round drawn
   Vue.js—none0/10

   No evidence pack items mention Vue's SSR streaming capabilities (e.g., renderToNodeStream / pipeToWebWritable in Vue's server-renderer package); all provided docs and community items focus on reactivity, TypeScript, tooling, and general framework praise/criticism rather than streaming SSR.

   The evidence pack contains no mention of SSR deployment, serverless functions, edge runtime adapters, or zero-config deployment tooling for Vue apps; all evidence is about core framework API, reactivity, TypeScript support, and community sentiment. While Vue does support SSR in principle, nothing here documents serverless/edge deployment without custom infrastructure, so this applicable axis is unmet. missing for 10: evidence of official SSR deployment guides, serverless/edge runtime adapters (e.g., Vercel/Netlify/Cloudflare Workers support), or a meta-framework deployment story.
