Accepted risks
Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| npm-metadata | suspicious-initial-version | AI (npm-metadata): pako 0.0.0 is the legitimate first release of a 12-year-old zlib library; the 0.0.0 version is not indicative of malicious intent for this established package. | ai | |
| semgrep | semgrep:dynamic-require | AI (semgrep): Dynamic require is in benchmark/benchmark.js, a dev-only benchmarking tool that loads impl files for comparison. Not runtime code and not a security concern. | ai | |
| semgrep | semgrep:shady-links-raw-ip | AI (semgrep): The 127.0.0.1 reference is in Gruntfile.js as a localhost test server URL for browser testing — a standard dev tooling pattern, not a malicious endpoint. Stable false positive for this package. | ai | |
| typosquat | typosquat.levenshtein:pino | AI (typosquat): pako is a well-established zlib compression library; name similarity to 'pino' (a logging library) is purely coincidental with no impersonation intent. Stable false positive for this package. | ai |
