Agent Quick Fix

Repair against the current npm contract, then keep the change narrow and source-backed.

Product: npm
Current-contract area: Native addon postinstall blocked by npm v12 allowScripts
Likely root cause: Install exits 0, but the native `.node` binary is absent and runtime throws MODULE_NOT_FOUND.
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.

Symptom

Install exits 0, but the native `.node` binary is absent and runtime throws MODULE_NOT_FOUND.

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.

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.
