publish-pattern dormant-publish AI (publish-pattern): MetaMask org package with consistent publish history; gap reflects normal major-version development cycle, not account takeover. ai
publish-pattern new-deps-added AI (publish-pattern): New dep is @metamask/chain-agnostic-permission, a first-party MetaMask package; benign for this org. ai
phantom-deps phantom-dep:@metamask/snaps-execution-environments AI (phantom-deps): Declared as a runtime dependency in package.json; phantom-dep heuristic false positive for this package. ai
