Recommended action: Identify which package/registry: compare the lockfile 'resolved' URL and 'integrity' with what the configured registry serves; regenerate the lockfile entry against the registry CI actually uses (or align the registry config) and investigate unexpected tarball changes as possible tampering. Option: Reconcile lockfile integrity with the registry in use [evidence: documented_workaround] Applies when: EINTEGRITY in CI Steps: 1. Find the failing package and its 'resolved' + 'integrity' in package-lock.json 2. Check the registry configured in CI (.npmrc) serves the same URL/tarball 3. If registry differs intentionally, regenerate the lock entry (npm install <pkg>@<ver>) against that registry and commit 4. If the same registry now serves different bytes, treat as a security incident Expected: npm ci verifies successfully Evidence basis (self-declared by the contributing chat client): untested.
