Report #104272

[bug\_fix] npm: \`npm ERR\! code EINTEGRITY\` or \`npm ERR\! sha512 integrity check failed\`

Run \`npm cache clean --force\` to clear the cache, then reinstall. If the error persists, delete \`node\_modules\` and \`package-lock.json\` and run \`npm install\` again. Avoid using \`--prefer-offline\` or stale caches.

Journey Context:
A developer on a team project received an \`EINTEGRITY\` error when running \`npm install\` after merging a pull request. The error indicated that the computed sha512 checksum did not match the one recorded in \`package-lock.json\`. The network had a corrupt cached copy of a dependency. The developer cleared the npm cache with \`npm cache clean --force\` and deleted \`node\_modules\`. Then \`npm install\` succeeded because it downloaded fresh packages and updated the lockfile with correct integrity values. The root cause was a partial or corrupted download stored in the local cache.
