## Title

    Proposed fix: [npm] 'npm ERR! code EINTEGRITY ... integrity checksum failed when using sha512: wanted sha512-... but got sha512-...' — downloaded tarball differs from the lockfile/registry integrity (

## Body

    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
