- Trust Save
- A package upgrade Arguss would have blocked despite the new version being available, because trust signals, like ownership transfer or a new maintainer, fired during the upgrade window. The name reflects what the agent did for the user: saved them from a potentially malicious update that a version-only auto-PR tool would have merged.
- AUTO-MERGE
- Verdict tier indicating the fix passes all three lenses cleanly. After you confirm action from a Scan assessment, Arguss opens a pull request for the upgrade; it does not merge PRs on GitHub. The envelope is conservative on purpose: patch or minor version bump, trust signals unchanged, blast radius bounded, real tests pass.
- REVIEW
- Verdict tier requiring a human decision. At least one veto fired during fix-confidence evaluation, trust signals shifted, the pipeline can't verify post-upgrade behavior, or the upgrade is a major version bump. The agent surfaces the reasons; the developer decides.
- DECLINE
- Verdict tier indicating no remediation is recommended. Typically applies when no fix version exists for the finding, or when multiple critical vetoes make even human review unproductive.
fix_kind.major
- Veto signal that fires when the available fix requires a major version bump (1.x → 2.x). Major bumps imply potential breaking changes and fall outside the auto-merge envelope by default, even when the upgrade is the only available fix.
trust.new_maintainer
- Veto signal that fires when a package added a new maintainer during the upgrade window, meaning between the user's current version and the proposed upgrade. New publishing identities are a well-documented attack vector for typosquats and supply chain takeovers.
trust.ownership_transferred
- Veto signal that fires when a package's primary maintainer changed during the upgrade window. Combined with
trust.new_maintainer, this is the highest-risk trust combination, typical of the xz-utils style attacks and historical npm credential theft incidents.
pipeline.test_reality
- Veto signal that fires when Arguss can't verify tests will run on the upgraded code. Four conditions must hold: a test script exists in
package.json, it isn't a no-op, real test files exist, and a workflow actually invokes them. If any fail, the fix cannot qualify for AUTO_MERGE because there's no way to verify the upgrade didn't break the user's project.
- CVSS
- Common Vulnerability Scoring System. A numeric score (0.0–10.0) representing how damaging a vulnerability could be if exploited. Sourced from NIST's National Vulnerability Database via OSV.dev. Severity, not urgency.
- EPSS
- Exploit Prediction Scoring System. A daily-updated probability (0.0–1.0, displayed as percent) that a CVE will be exploited in the next 30 days. Sourced from FIRST.org. Probability, not severity.
- KEV
- CISA's Known Exploited Vulnerabilities catalog. A federal list of CVEs with documented active exploitation in the wild. Federal agencies have a binding patching deadline; for everyone else, presence on KEV is the strongest "this is being used right now" signal available. Sourced directly from CISA.
- Project Risk Score (PRS)
- A weighted blend of the three lens subscores (40% vulnerability, 30% trust, 30% pipeline) producing an overall 0–100 indicator of the project's dependency health. Useful for at-a-glance triage; the per-finding fix-confidence verdicts are what drive automated decisions.
