Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
maintainer-change maintainer-takeover AI (maintainer-change): 2019 handoff to facebook's metro-bot, stable 2500+ days, matches repo=facebook/metro. ai
provenance publisher-changed-stale AI (provenance): Same long-stable facebook/metro-bot transition, not a fresh takeover. ai
bogus-package bogus-package AI (bogus-package): Tiny utility lib by Facebook metro team; sparse README/no-deps is expected. ai
typosquat typosquat.levenshtein:mobx AI (typosquat): ob1 is a legitimate Facebook/Metro monorepo package for 0/1-based offset types; name similarity to mobx is purely coincidental with no impersonation intent. ai
phantom-deps phantom-dep:flow-enums-runtime AI (phantom-deps): flow-enums-runtime is a legitimate declared dependency used by Flow-typed Metro packages; phantom-dep detection is a false positive for this ecosystem. ai

v0.87.0

1 finding
INFO Has SLSA provenance attestation provenance

Published via CI/CD with Sigstore attestation (predicate: https://slsa.dev/provenance/v1). This is the strongest supply chain integrity signal.

v0.86.0

1 finding
INFO Has SLSA provenance attestation provenance

Published via CI/CD with Sigstore attestation (predicate: https://slsa.dev/provenance/v1). This is the strongest supply chain integrity signal.

v0.65.0

2 findings
MEDIUM Publisher changed: motiz88 → metro-bot (on 2021-01-28, unremoved on npm for 1998d) provenance

This version was published by a different npm account (metro-bot) than the most recent previously approved version (motiz88) on 2021-01-28. It has since remained available on npm for 1998 days without being unpublished, which is inconsistent with an account takeover — those are typically removed by npm shortly after discovery.

LOW No provenance attestation provenance

Package was published without Sigstore provenance. Consider requesting the maintainer enable provenance via CI/CD.

v0.55.0

2 findings
MEDIUM Publisher changed: motiz88 → metro-bot (on 2019-07-04, unremoved on npm for 2572d) provenance

This version was published by a different npm account (metro-bot) than the most recent previously approved version (motiz88) on 2019-07-04. It has since remained available on npm for 2572 days without being unpublished, which is inconsistent with an account takeover — those are typically removed by npm shortly after discovery.

LOW No provenance attestation provenance

Package was published without Sigstore provenance. Consider requesting the maintainer enable provenance via CI/CD.

v0.54.1

1 finding
LOW No provenance attestation provenance

Package was published without Sigstore provenance. Only ~12% of npm packages have provenance, so this is common but not ideal.
