    "error": "Ignored build scripts: @swc/core, better-sqlite3. Run \"pnpm approve-builds\" to pick which dependencies should be allowed to run scripts.",
    "body": "## Symptom\nAfter upgrading to pnpm 10, `pnpm install` succeeds but prints a warning like:\n\n```\nIgnored build scripts: @swc/core, better-sqlite3.\nRun \"pnpm approve-builds\" to pick which dependencies should be allowed to run scripts.\n```\n\nThen native modules fail at runtime (e.g. `better-sqlite3` bindings missing, `esbuild`/`sharp`/`prisma` binaries not downloaded, `husky` hooks not installed). Older advice assumes `postinstall` of dependencies always runs.\n\n## Cause\npnpm 10.0.0 (2025-01-07): \"Lifecycle scripts of dependencies are not executed during installation by default!\" Only packages explicitly allow-listed may run `preinstall`/`install`/`postinstall`. Your own project's scripts still run.\n\n## Fix\nInteractive: run `pnpm approve-builds` after `pnpm install` and select the packages; it records the allow-list and runs their builds.\n\nOr declare it explicitly (pnpm 10):\n\n```json\n// package.json\n{\n  \"pnpm\": {\n    \"onlyBuiltDependencies\": [\"esbuild\", \"better-sqlite3\", \"@swc/core\"]\n  }\n}\n```\n\nIn later pnpm 10.x releases `pnpm approve-builds` writes `onlyBuiltDependencies` into `pnpm-workspace.yaml` instead (creating that file if needed). To silence the warning for packages whose scripts you do NOT want, list them in `ignoredBuiltDependencies`. To restore the pre-v10 run-everything behaviour (not recommended): `\"pnpm\": { \"neverBuiltDependencies\": [] }`.\n\nCommit the allow-list: CI starts from a clean store, so a local-only approval still leaves CI with the warning. Note pnpm 11 removed `onlyBuiltDependencies` in favour of `allowBuilds` (see the pnpm 11 entry).\n\n## Verify\nDelete `node_modules`, run `pnpm install`: no \"Ignored build scripts\" line, and the native package loads (e.g. `node -e \"require('better-sqlite3')\"`).\n\n## Sources\n- https://github.com/pnpm/pnpm/releases/tag/v10.0.0\n- https://github.com/pnpm/pnpm/issues/9045\n- https://github.com/pnpm/pnpm/issues/9361",
