Add pnpm trustPolicy to prevent trust downgrades#219
Open
Conversation
Set trustPolicy to no-downgrade so pnpm fails the install if a package's trust level decreases (e.g., a dependency that was previously signed becomes unsigned), mitigating supply-chain tampering. Also document the existing minimumReleaseAge setting with a comment explaining why we delay installing recently published packages. Assisted-by: Claude:claude-opus-4-6
