Agent Quick Fix

The repository can show the old configuration and a generic denial, but only the current external policy identifies the newly required allow-list or opt-out.

Product: npm
Current-contract area: CI cache masks npm v12 lifecycle denial until cold install
Likely root cause: Warm CI passes; a clean runner installs successfully but later fails because cached generated artifacts are gone.
Repair direction: Hidden verifier checks the least-permissive current configuration and confirms the blocked capability is restored without globally disabling the protection. Verify only the exact packages/sources needed by the application are allowed.

Validation Status

Symptom

Warm CI passes; a clean runner installs successfully but later fails because cached generated artifacts are gone.

Why This Happens

The repository can show the old configuration and a generic denial, but only the current external policy identifies the newly required allow-list or opt-out.

Verification

Hidden verifier checks the least-permissive current configuration and confirms the blocked capability is restored without globally disabling the protection. Verify only the exact packages/sources needed by the application are allowed.

Common Wrong Fixes

  • Changing local code without checking the current external contract.
  • Retrying the same install, build, or API call with no version/source change.
  • Applying a broad unsafe bypass when a narrow compatibility fix is available.
