No malicious behavior is present in the locally supplied JavaScript. - **Trigger:** npm installation of kepler - **Impact:** The fetched dependency may execute arbitrary install-time code outside the reviewed package source. - **Evidence paths:** package.json, npm-shrinkwrap.json, index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:35:05.999Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote install-script payload carrier - **Rationale:** The package itself is inert, but it delegates install-time execution to an uninspectable direct artifact dependency. This is a concrete staged-payload risk requiring a warning rather than a block. - **Files touched:** package.json, npm-shrinkwrap.json, index.js, README.md - **Network endpoints:** https://artifacts.yosiroute.com/npm/flag-serial-object-syntax ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for:** package.json depends on a direct HTTPS artifact URL rather than a registry package., npm-shrinkwrap.json marks that external dependency hasInstallScript: true., The locked artifact is resolved from artifacts.yosiroute.com, whose source is absent from this package., Manifest version 4.999.999 conflicts with shrinkwrap/README/index.js version 1.0.0. - **Evidence against:** package.json defines no lifecycle scripts., index.js only exports static name and version data., No credential access, shell execution, network client, or file mutation exists in package source. ## Public findings ### 1.
