Issue #46 (Phase A only — Phase B human rating still pending, issue stays open). Adds the data-collection half of the calibration milestone: - scripts/calibration_runner.sh — runs 20 fixed balanced-depth queries across 4 categories (factual, comparative, contradiction-prone, scope-edge), 5 each, capturing per-run logs to docs/stress-tests/M3.3-runs/. - scripts/calibration_collect.py — loads every persisted ResearchResult under ~/.marchwarden/traces/*.result.json and emits a markdown rating worksheet with one row per run. Recovers question text from each trace's start event and category from the run-log filename. - docs/stress-tests/M3.3-rating-worksheet.md — 22 runs (20 calibration + caffeine smoke + M3.2 multi-axis), with empty actual_rating columns for the human-in-the-loop scoring step. - docs/stress-tests/M3.3-runs/*.log — runtime logs from the calibration runner, kept as provenance. Gitignore updated with an exception carving stress-test logs out of the global *.log ignore. Note: M3.1's 4 runs predate #54 (full result persistence) and so are unrecoverable to the worksheet — only post-#54 runs have a result.json sibling. 22 rateable runs is still within the milestone target of 20–30. Phases B (human rating) and C (analysis + rubric + wiki update) follow in a later session. This issue stays open until both are done.

╭─────────────────────────────────── Answer ───────────────────────────────────╮
|
||
│ For large enterprise frontends in 2026, React and Vue each offer distinct │
|
||
│ advantages, and the best choice depends on organizational priorities. │
|
||
│ │
|
||
│ **Market Position & Adoption:** React dominates with ~42% market share among │
|
||
│ professional developers (2025 State of JavaScript survey) and ~68% among │
|
||
│ enterprise applications globally, while Vue holds ~28% developer share and │
|
||
│ ~18% enterprise share. React powers Facebook, Netflix, Airbnb, and Uber; Vue │
|
||
│ drives Alibaba, GitLab, and Nintendo. Some 80% of enterprise teams use React │
|
||
│ directly or via Next.js. [Sources 1, 4, 25] │
|
||
│ │
|
||
│ **Performance:** Both frameworks use a virtual DOM. Vue 4 showed 15% faster │
|
||
│ initial render times than React 19 in large-scale applications with │
|
||
│ thousands of components (JavaScript Performance Consortium 2025 benchmarks). │
|
||
│ However, React 19's concurrent rendering features provide superior │
|
||
│ responsiveness during complex user interactions. In micro-benchmarks, Vue │
|
||
│ 3.4 creates 1,000 rows in 38ms vs React 19's 42ms, and Vue's bundle size is │
|
||
│ smaller (33KB vs 44KB min+gzip). The performance gap continues to narrow. │
|
||
│ [Sources 1, 25] │
|
||
│ │
|
||
│ **React 19 Architecture Shifts:** React 19 introduces a built-in compiler │
|
||
│ that automates memoization (making useMemo/useCallback largely redundant), │
|
||
│ native Server Components for zero-bundle-size dependencies and direct │
|
||
│ database access, a new Actions API for simplified async form handling, and │
|
||
│ the `use` hook for streamlined data fetching. These changes significantly │
|
||
│ reduce boilerplate and technical debt for enterprise teams. [Sources 18, 19, │
|
||
│ 20] │
|
||
│ │
|
||
│ **Vue's Enterprise Momentum:** Vue 3's Composition API enables better logic │
|
||
│ reuse across large codebases. Pinia (the official state manager) is │
|
||
│ TypeScript-first and lightweight. Nuxt 3 handles SSR. Vue's natural │
|
||
│ TypeScript support and Vite-powered tooling make it increasingly attractive │
|
||
│ for enterprise adoption. Fortune 500 companies, SaaS platforms, and │
|
||
│ government tech teams are growing adopters. [Sources 12, 15] │
|
||
│ │
|
||
│ **Learning Curve & Developer Experience:** Vue uses standard HTML/CSS/JS │
|
||
│ with Single File Components, making it easier to onboard developers with │
|
||
│ traditional web backgrounds. React uses JSX (combining HTML and JavaScript), │
|
||
│ which has a steeper initial curve but becomes natural quickly. Vue's │
|
||
│ official routing and state solutions (Vue Router, Pinia) reduce │
|
||
│ architectural decision-making overhead. React requires selecting from a │
|
||
│ broader ecosystem (Redux/Zustand, React Router, etc.), offering more │
|
||
│ flexibility but more upfront choices. [Sources 1, 13, 14] │
|
||
│ │
|
||
│ **Ecosystem & Hiring:** React has ~44M+ weekly npm downloads vs Vue's │
|
||
│ ~4.5M+. React has 225K+ GitHub stars vs Vue's 207K+. Fortune 500 adoption is │
|
||
│ 47% React vs 12% Vue. React job postings vastly outnumber Vue's (e.g., │
|
||
│ 3,200+ vs 680+/month in one market). React's ecosystem is larger and more │
|
||
│ mature, making hiring and long-term support easier for large enterprises. │
|
||
│ [Sources 14, 25] │
|
||
│ │
|
||
│ **Enterprise Scalability:** React's flexibility and massive ecosystem make │
|
||
│ it the safer long-term choice for large, complex, cross-team enterprise │
|
||
│ platforms. Angular is also a strong contender here with built-in DI, forms, │
|
||
│ and strict structure. Vue excels when time-to-market and developer │
|
||
│ productivity are top priorities and when teams want a progressive, │
|
||
│ opinionated setup with lower onboarding cost. [Sources 13, 14, 23] │
|
||
│ │
|
||
│ **Recommendation:** For most large enterprise frontends in 2026, React │
|
||
│ (often via Next.js) remains the dominant and lowest-risk choice due to its │
|
||
│ ecosystem size, hiring market, enterprise adoption, and React 19's │
|
||
│ architectural improvements. Vue is a compelling choice for enterprises │
|
||
│ prioritizing developer velocity, lower onboarding costs, and smaller bundle │
|
||
│ sizes, particularly in Asia-Pacific markets or mid-size SaaS platforms. │
|
||
│ Neither choice is technically wrong—both are production-proven at scale. │
