Now I have enough information. Let me create a comprehensive analysis.\n\nSummary: Analysis of doctolib/actions/setup-node\n\nBased on my thorough exploration of the codebase, here's a comprehensive analysis of the setup-node action and how it compares to other package manager solutions:\n\n1. What does setup-node currently do?\n\nThe doctolib/actions/setup-node action is a composite GitHub Action that:\n- Sets up Node.js environment with automatic npm version detection from package.json's .engines.npm field\n- Installs dependencies using npm with customizable commands\n- Provides S3-based caching for both node_modules/ and npm cache (.npm/)\n- Auto-detects multiple node_modules directories in monorepo projects\n- Runs CodeArtifact login for internal Doctolib npm packages\n- Validates lock files to prevent cache invalidation\n- Supports customizable install and postinstall commands\n\nKey features:\n- Highly optimized for Doctolib's self-hosted runners\n- Uses custom S3 caching (via doctolib/actions/cache) instead of GitHub Actions cache\n- Architecture-aware caching (includes runner.arch in cache keys to prevent ARM64/AMD64 conflicts)\n- Works with monorepos through working-directory and node-modules-paths inputs\n\n2. Does it have pnpm support or package manager selection?\n\nNo pnpm support. The README explicitly states: \"Works only with NPM for now\"\n\nKey npm-specific constraints in the action:\n- All commands use npm (line 26: npm ci, line 41: npm config get cache, etc.)\n- Install-check command hardcoded to npm: npm i --no-audit --no-fund --ignore-scripts\n- Postinstall command defaults to: npm run postinstall --if-present\n- No package manager detection or input parameter\n\n3. What inputs does it accept?\n\n| Input | Type | Default | Description |\n|-------|------|---------|-------------|\n| node-version | string | (none) | Version spec for Node.js (e.g., \"20.x\") |\n| node-version-file | string | .nvmrc | File containing version spec |\n| architecture | string | (system default) | Target architecture (x86, x64) |\n| check-latest | boolean | false | Check for latest matching version |\n| disable-cache | boolean | false | Skip caching |\n| postinstall-command | string | npm run postinstall --if-present | Custom postinstall command |\n| install-command | string | npm ci | Custom install command |\n| install-check-command | string | npm i --no-audit --no-fund --ignore-scripts | Lock file validation command |\n| lock-file | string | package-lock.json | Path to lock file |\n| node-modules-paths | string | (auto-detect) | Paths to cache |\n| working-directory | string | . | Working directory |\n| get-cache-location-command | string | npm config get cache | Get npm cache location |\n| npm-version | string | (from .engines.npm) | Specific npm version to install |\n| enable-lock-check | boolean | false | Enable lock file change validation |\n\n4. How does it compare to the official actions/setup-node?\n\nComparison with actions/setup-node@v4:\n\n| Aspect | actions/setup-node (Official) | doctolib/actions/setup-node |\n|--------|-------------------------------|--------------------------|\n| Package Manager Support | npm, pnpm, yarn (via corepack) | npm only |\n| Caching | GitHub Actions cache | S3-based custom cache |\n| Runner Type | Works on GitHub-hosted & self-hosted | Self-hosted runners only |\n| MultiPlatform | Yes (GHA runners) | Doctolib self-hosted only |\n| Package Manager Selection | Automatic detection or setup via inputs | No selection capability |\n| Monorepo Support | Limited | Advanced (auto-detect + explicit paths) |\n| Customization | Limited | Highly customizable (all commands) |\n| CodeArtifact Integration | None | Built-in Doctolib CodeArtifact setup |\n\nKey difference: The official action is universal and supports multiple package managers, while Doctolib's version is deeply optimized for their specific infrastructure (self-hosted runners, S3 caching, CodeArtifact integration, npm-only).\n\n5. Is there any precedent in the codebase for choosing between package managers?\n\nYes, clear precedent exists:\n\nThe docto-crypt repository contains separate workflows for npm vs pnpm:\n\n1. publish.yml (npm):\n   - Uses: doctolib/actions/setup-node@01e54a0351a31496d12f68c2cd991d19399ad558\n   - Runs: npm publish\n\n2. publish-pnpm.yml (pnpm):\n   - Uses BOTH:\n     - doctolib/actions/setup-node@... (still for Node.js setup)\n     - doctolib/actions/setup-pnpm@main (separate for pnpm)\n   - Runs: pnpm publish --no-git-checks\n   - Includes performance metrics comparing both approaches\n\nPattern observed: The precedent is to keep setup-node and setup-pnpm separate rather than combining them into one action with package manager selection.\n\nAdditional Context: setup-pnpm Action\n\nThe doctolib/actions/setup-pnpm action (very recently added, still in \"Unreleased\" state in CHANGELOG):\n\n- Minimal design: Only 4 inputs (pnpm-version, run-install, cache, working-directory)\n- Lighter implementation: Uses official pnpm/<REDACTED> and GitHub Actions cache (not S3)\n- Separate concern: Does NOT include CodeArtifact login or npm version management\n- Philosophy: Simpler, single-purpose action vs setup-node's comprehensive npm experience\n\nRecommendations for docto-crypt pnpm workflow\n\nBased on this analysis, the current approach in publish-pnpm.yml (using both setup-node for Node.js and setup-pnpm for pnpm) follows the established precedent and is the recommended pattern. Advantages:\n\n1. Separation of concerns: Node.js setup vs package manager setup\n2. Non-breaking: Doesn't require modifying the mature setup-node action\n3. Consistency: Follows the pattern of separate setup actions for each package manager\n4. Future-proof: If setup-node ever needs to support multiple package managers, this separation makes it cleaner\n5. Minimal maintenance: Each action focuses on its responsibility\n\nNot recommended: Extending setup-node to support pnpm would introduce complexity to an action specifically optimized for npm, and would diverge from the codebase's established pattern.\n\nAbsolute file paths for reference:\n- /Users/USER/workspace/doctolib/actions/setup-node/action.yml\n- /Users/USER/workspace/doctolib/actions/setup-pnpm/action.yml\n- /Users/USER/workspace/doctolib/docto-crypt/.github/workflows/publish.yml\n- /Users/USER/workspace/doctolib/docto-crypt/.github/workflows/publish-pnpm.yml`",
