      "README.md": "# Benchmark reproduzível — npm, pnpm, Yarn e Bun\n\nEste diretório mede instalação de dependências; não mede o desempenho da\naplicação em produção. A fixture é uma API Fastify/TypeScript com 19 dependências\ndiretas em versões exatas. Cada gerenciador resolve suas próprias dependências\ntransitivas; o protocolo não presume que essas árvores sejam idênticas. Depois de\ncada cenário, o harness compila a fixture e\nexecuta um teste HTTP real com o runtime Node.js.\n\n## Versões comparadas no recorte de 30/08/2026\n\n- npm 12.0.2, linker padrão `hoisted`;\n- pnpm 11.24.0, dist-tag `latest`, linker padrão `isolated`;\n- Yarn 4.18.0 em PnP e, como controle de compatibilidade, em `node-modules`;\n- Bun 1.4.0, linker padrão `hoisted` para pacote único.\n\npnpm 12.1.0 já existia no canal `next-12`, mas não era o dist-tag `latest`. Para\nnão misturar a troca de gerenciador com a adoção de uma reescrita recém-lançada,\no comparativo principal usa pnpm 11.24.0.\n\n## Protocolo\n\n- **Frio:** lockfile já gerado, cache isolado vazio, rede habilitada.\n- **Quente:** mesmo lockfile, cache aquecido, artefato do projeto removido e rede\n  desabilitada por uma opção explícita de cada CLI. No Yarn, o harness também\n  define `YARN_ENABLE_NETWORK=false`.\n- Scripts de lifecycle ficam desativados em todos os gerenciadores. Isso evita\n  comparar políticas de segurança diferentes como se fossem velocidade.\n- São cinco execuções frias e dez quentes por padrão. A ordem gira de forma\n  determinística: cada cenário ocupa cada posição uma vez no frio e duas no\n  quente.\n- O resumo publica mediana, mínimo e máximo. Com amostras tão pequenas, o p95\n  seria apenas o maior valor e daria uma falsa impressão de precisão de cauda.\n- Uso do projeto e do cache é registrado separadamente em KiB alocados por `du`.\n  O número de `node_modules` sozinho não deve ser chamado de “disco total”.\n- O Yarn PnP não cria `node_modules`; seu cache faz parte do custo e aparece numa\n  coluna separada. O cenário `node-modules` impede que uma falha específica do\n  linker seja atribuída incorretamente ao Yarn inteiro.\n- Projeto e cache/store são reportados separadamente. Somar as duas travessias\n  pode contar os mesmos blocos mais de uma vez quando o filesystem usa hardlinks\n  ou clone-on-write; um total físico exige medição deduplicada por inode/bloco.\n\nOs testes frios incluem rede pública e, portanto, são uma fotografia desta\nmáquina e deste horário. O resultado quente isola melhor resolução e\nmaterialização, mas continua dependente do filesystem e do sistema operacional.\n\n## Como repetir\n\nInstale CLIs exatas fora do projeto:\n\n```sh\nnpm install --prefix /private/tmp/codeinit-pm-tools --no-audit --no-fund \\\n  npm@12.0.2 pnpm@11.24.0 @yarnpkg/cli-dist@4.18.0 bun@1.4.0\n```\n\nExecute:\n\n```sh\nnode run.mjs\n```\n\nPara mudar quantidade de amostras ou caminhos:\n\n```sh\nCODEINIT_PM_COLD_RUNS=5 \\\nCODEINIT_PM_WARM_RUNS=10 \\\nCODEINIT_PM_TOOLS=/caminho/para/node_modules/.bin \\\nCODEINIT_PM_BENCH_WORK=/private/tmp/meu-benchmark \\\nnode run.mjs\n```\n\nOs arquivos gerados ficam em `resultados/raw.json`, `summary.json` e\n`summary.csv`. Não rode dois benchmarks simultâneos no mesmo `WORK`.\n\nConfira contagem, rotação, bloqueio de rede, estatísticas e build/teste:\n\n```sh\nnode derive-summary.mjs\nnode export-public.mjs\nnode validate.mjs\n```\n\n`derive-summary.mjs` recalcula o resumo a partir das amostras sem repetir as\ninstalações. A mediana de uma quantidade par é a média dos dois valores centrais.\nO validador também cruza o resumo com a tabela do artigo e o bundle público.\n\nPara gerar o bundle público que acompanha o artigo — dados, código da bancada e\nprova de migração — execute `node export-public.mjs`. A saída fica em\n`99-website-code/public/dados/package-managers-2026.json`.\n\n## O que estes dados não provam\n\n- Não provam que um gerenciador será o mais rápido em outro projeto.\n- Não comparam runtime Node.js e runtime Bun.\n- Não medem addons nativos nem scripts de instalação.\n- Não substituem teste de CI, Docker e plataforma de produção do leitor.\n- Não transformam diferenças de milissegundos em justificativa automática para\n  migrar um repositório estável.\n",

O roteiro\nconfirma que nenhum `pnpm-lock.yaml` surge antes de `pnpm import` e prova três\nestados:\n\n1. npm hoisted deixa a aplicação executar e mascara o manifesto incompleto;\n2. depois de `pnpm import`, pnpm isolated recusa o import da aplicação;\n3. `pnpm --filter @codeinit/api add is-number@7.0.0` corrige a declaração e a\n   instalação frozen passa.\n\nExecute depois de instalar as CLIs exatas usadas pela bancada principal:\n\n```bash\nnode run.mjs\n```\n\nO resultado auditável fica em `resultado.json`. A pasta de trabalho é temporária\ne pode ser apagada sem afetar a fixture.\n",
