Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
source-diff obfuscated-file:index.cjs AI (source-diff): index.cjs is a standard minified CJS bundle; content is readable iframe/postMessage transport logic with no malicious patterns. ai
provenance publisher-changed AI (provenance): Transition to GitHub Actions CI publisher is confirmed by SLSA provenance attestation; consistent with org-level CI migration. ai
phantom-deps phantom-dep:tslib AI (phantom-deps): tslib is a well-known implicit TypeScript runtime dep; stable false positive for TS packages. ai
phantom-deps phantom-dep:@uniswap/sdk-core AI (phantom-deps): Peer/type dependency referenced in config; not a direct import pattern is expected. ai
phantom-deps phantom-dep:@cowprotocol/cow-sdk AI (phantom-deps): Same-org dependency; phantom-dep heuristic unreliable for monorepo packages. ai
phantom-deps phantom-dep:@cowprotocol/sdk-bridging AI (phantom-deps): Same-org dependency; phantom-dep heuristic unreliable for monorepo packages. ai
phantom-deps phantom-dep:@web3-react/types AI (phantom-deps): Types-only dependency; phantom-dep false positive for type packages. ai
provenance missing-githead AI (provenance): SLSA attestation present; gitHead absence is cosmetic and doesn't undermine supply chain integrity for this package. ai
bogus-package bogus-package AI (bogus-package): Part of cowprotocol/cowswap monorepo; sparse README and missing keywords are typical for internal library packages. ai

v2.2.6

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.

v2.2.5

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.

v2.2.4

2 findings
HIGH Missing gitHead — previous versions had it provenance

This version has no gitHead field linking it to a source commit, but previous versions did. This suggests the publish environment changed. Published by: GitHub Actions.

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.

v2.2.3
