Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance missing-githead AI (provenance): Package has SLSA provenance attestation which supersedes gitHead as a supply chain integrity signal. Missing gitHead is a minor CI config difference, not a risk indicator for this package. ai
phantom-deps phantom-dep:thingies AI (phantom-deps): thingies is a declared runtime dependency in package.json from the same ecosystem; phantom-dep finding reflects indirect usage pattern, not a real risk. ai
