Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance slsa-provenance AI (provenance): Hardhat publishes via GitHub Actions CI with SLSA attestation; this is the expected publish pattern going forward. ai
phantom-deps phantom-dep:mnemonist AI (phantom-deps): mnemonist is listed as a runtime dep in package.json; phantom-dep heuristic false positive. ai
provenance publisher-changed AI (provenance): Hardhat v3 is published via GitHub Actions CI with SLSA attestation; automated publisher is expected for this org. ai
semgrep semgrep:child-process-import AI (semgrep): Hardhat legitimately uses child_process for running scripts, compilers, and VS Code extension management — core features. ai
semgrep semgrep:hex-decode AI (semgrep): Hex decoding of Solidity function selectors is core EVM/compiler functionality for stack trace analysis. ai
semgrep semgrep:api-obfuscation-reflect AI (semgrep): Reflect.get() is used inside a Proxy for deep-freezing user config objects — a legitimate JavaScript pattern, not obfuscation. ai
semgrep semgrep:shady-links-raw-ip AI (semgrep): 127.0.0.1:8545 is the default localhost RPC URL for Hardhat Network — expected and documented default configuration. ai
semgrep semgrep:dynamic-require AI (semgrep): Dynamic require is used to load user config files and plugins — a fundamental design feature of Hardhat's extensible config system. ai
semgrep semgrep:silent-process-exec AI (semgrep): Hardhat's analytics.ts spawns a detached Node.js subprocess to report telemetry consent — documented behavior, not a reverse shell or miner. ai
semgrep semgrep:silent-process-exec-var AI (semgrep): Same telemetry consent subprocess as silent-process-exec; legitimate documented Hardhat analytics behavior. ai
semgrep semgrep:env-spread AI (semgrep): process.env spread is used to pass environment to a local Sentry reporter subprocess — standard child process pattern, not exfiltration. Stable for this package. ai

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.
