Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
semgrep semgrep:child-process-import AI (semgrep): This is a CLI tool that legitimately spawns child processes to run shim compliance tests. child_process usage is expected and benign for this package. ai
typosquat typosquat.levenshtein:hapi AI (typosquat): @es-shims/api is a scoped package under the official es-shims org by ljharb; Levenshtein comparison to 'hapi' is a false positive that will never be relevant. ai
typosquat typosquat.levenshtein:pg AI (typosquat): @es-shims/api is a scoped package under the official es-shims org; comparison to 'pg' is a false positive. ai
typosquat typosquat.levenshtein:joi AI (typosquat): @es-shims/api is a scoped package under the official es-shims org; comparison to 'joi' is a false positive. ai
typosquat typosquat.levenshtein:ajv AI (typosquat): @es-shims/api is a scoped package under the official es-shims org; comparison to 'ajv' is a false positive. ai
semgrep semgrep:dynamic-require AI (semgrep): Dynamic require is used to load a target package.json for ES shim API validation — expected CLI behavior, not arbitrary code execution. ai
