feat(supply-chain): SBOM, vuln scanning, signed releases, dep cleanup#511
Conversation
Implements defense/aerospace supply-chain hardening (EO 14028 / SLSA): - govulncheck@v1.1.4 runs on every binary build (both amd64 + arm64); blocks the build on any known Go vulnerability - Trivy v0.36.0 scans the container image on every release; attaches JSON report + SARIF to GitHub Security tab as signed evidence - Syft (anchore/sbom-action) generates SPDX + CycloneDX SBOMs from the built container image and Go source tree per release - Cosign keyless signing (Sigstore/Rekor OIDC) on container manifest and both release binaries; .bundle files ship as release artifacts for offline air-gap/Zarf verification - SLSA Level 3 provenance via slsa-github-generator pinned by commit SHA (f7dd8c5); provenance .intoto.jsonl attached to GitHub release - Benchmark suite removed: ClickHouse/clickhouse-go and jackc/pgx dropped from go.mod (25 direct deps, down from 27); benchmarks moved to github.com/Basekick-Labs/arc-benchmarks

Code Review
This pull request extracts the benchmark suite to a dedicated repository, removing numerous benchmark scripts, configurations, and results from the codebase, which cleans up the project's dependencies (such as removing clickhouse-go and pgx). It also updates the release notes to document new supply-chain hardening measures. The review feedback correctly identifies a security issue in the documented cosign verification commands, where using a wildcard regular expression (.*) for the certificate identity defeats the security benefits of keyless signing; the commands should be updated to restrict verification to the specific repository.
Important
The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

Code Review
This pull request extracts the benchmark suite into a dedicated repository, removing several benchmark files and database driver dependencies (such as ClickHouse and pgx) from the Go module. It also updates the release notes to document new supply-chain hardening features, including SBOM generation, signed releases, and SLSA Level 3 provenance. Feedback on the release notes highlights a security risk in the documented cosign verification command, where using a wildcard regular expression for the certificate identity defeats the purpose of cryptographic verification.

Using --certificate-identity-regexp ".*" in the cosign verification command is a security risk. It allows any OIDC token issued by GitHub Actions (from any repository/attacker) to pass verification, defeating the purpose of cryptographic signing. It should be restricted to the specific repository or workflow, for example: --certificate-identity-regexp "https://github.com/basekick-labs/arc/.*".
Using .* for --certificate-identity-regexp accepts signatures from any GitHub Actions workflow on any repo, defeating keyless signing. Scoped to ^https://github.com/Basekick-Labs/arc/ (case-preserving — GitHub OIDC tokens use original org/repo casing, not lowercase).

Code Review
This pull request extracts the benchmark suite into a dedicated repository, deleting all benchmark-related files and configurations from the main codebase. This extraction allows for the cleanup of go.mod and go.sum by removing unused dependencies like clickhouse-go and pgx. Additionally, the release notes are updated to document these dependency changes and highlight new supply-chain hardening features. Feedback on the changes identifies that github.com/valyala/fasthttp was incorrectly promoted to a direct dependency in go.mod without any corresponding imports, and recommends running go mod tidy to demote or remove it.

The dependency github.com/valyala/fasthttp has been promoted to a direct dependency in go.mod. Since no Go files were added or modified in this pull request to introduce a direct import of fasthttp, and it was previously an indirect dependency, it should not be listed as a direct dependency. This contradicts the PR's goal of dependency cleanup and the stated count of 25 direct dependencies (it would be 26 with fasthttp directly required). Running go mod tidy should automatically demote or remove it.

G2 — fasthttp promotion: declined, not a bug.
Direct dep count is still 25 — fasthttp was already in @gemini-code-assist please review |
fasthttp was incorrectly promoted to a direct dep by go mod tidy when ClickHouse/pgx were dropped. The import in query_rbac_test.go predates this PR — not a change introduced here. Restoring // indirect to keep the diff minimal and the direct dep count accurate at 25.

Code Review
This pull request documents the new supply-chain hardening features in the release notes for version 2026.06.2, including SBOM generation, vulnerability scanning, and SLSA Level 3 provenance. It also removes the benchmark suite and its associated dependencies, such as ClickHouse and PostgreSQL drivers, from the Go module. All of the reviewer's comments have been filtered out as they pertain to version numbers in non-code documentation, so there is no additional feedback to provide.

This pull request updates the release notes to document new supply-chain hardening features and reflects the extraction of the benchmark suite to a dedicated repository, which includes removing several benchmark files and cleaning up unused dependencies in go.mod and go.sum. The review feedback recommends strengthening the security of the documented verification commands by restricting the Cosign certificate identity regex to the specific release workflow and adding source tag verification to the SLSA verifier command.

Using a broad regular expression like ^https://github.com/Basekick-Labs/arc/ allows any workflow run within the repository (including development, testing, or pull request workflows if they have write/id-token permissions) to produce signatures that pass verification. To adhere to the principle of least privilege, it is highly recommended to restrict the identity to the specific release workflow file (e.g., release.yml) by using: cosign verify-blob arc-linux-amd64 --bundle arc-linux-amd64.bundle --certificate-identity-regexp "^https://github.com/Basekick-Labs/arc/\.github/workflows/release\.yml@" --certificate-oidc-issuer https://token.actions.githubusercontent.com

Similarly to the binary verification, the container image verification regex should be restricted to the specific release workflow file (e.g., release.yml) to prevent other workflows in the repository from producing signatures that pass verification: cosign verify ghcr.io/basekick-labs/arc:VERSION --certificate-identity-regexp "^https://github.com/Basekick-Labs/arc/\.github/workflows/release\.yml@" --certificate-oidc-issuer https://token.actions.githubusercontent.com

To ensure the artifact was built from the expected release tag rather than an arbitrary commit or branch in the repository, it is highly recommended to include the --source-tag vVERSION parameter in the slsa-verifier command: slsa-verifier verify-artifact arc-linux-amd64 --provenance-path arc-VERSION.intoto.jsonl --source-uri github.com/Basekick-Labs/arc --source-tag vVERSION
