No SLSA provenance npm registry signatures gitHead linked

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): Both lharker and blickly are Google engineers on the Closure Compiler project; maintainer transitions within the same org are expected and not a risk signal for this package. ai
semgrep semgrep:child-process-import AI (semgrep): child_process is used in build_compiler.js, a dev/build script invoked only during testing, not at install or runtime. Expected for a compiler toolchain package. ai
