Every published artifact is now cryptographically verifiable as built by this repo's Release workflow: npm publishes carry npm provenance (OIDC, shows the Provenance badge on npmjs.com), and the GitHub Release bundles + SHA256SUMS get signed build attestations via actions/attest-build-provenance, verifiable with `gh attestation verify <file> -R colbymchenry/codegraph`. pack-npm.sh now writes a repository field into the generated shim and per-platform package.jsons — npm --provenance refuses to publish without one matching the repo — and the root package.json gains the same field.
