Summary by cubic

Adopts a hardened Go install workflow and pins Go module integrity to strengthen the supply chain (Shai-Hulud defense). Aligns with the Linear rollout across Go repos.

• New Features
  • Adds .github/workflows/go-hardened.yml reusing go-install-hardened.yml from allora-network/ci-workflows-private, pinned to the v1 head, with go_version: stable and cgo_enabled: '0'.
  • Adds go.env with GOPROXY=https://proxy.golang.org,direct, GOSUMDB=sum.golang.org, and GOFLAGS=-mod=readonly.

^{Written for commit da1d6ca. Summary will update on new commits.}

Blocked on signed-commits protection

This PR is SHA-pinned to ci-workflows-private@fa8a0e1361216ec0c75e4d822f648248083e229b, which contains a non-existent actions/setup-go@3041bf56... SHA. The fix landed at ci-workflows-private@0d80a856ef798b01a39f65cb88a5cf7e74e4ebf9.

A re-pin commit is staged locally but cannot be pushed because this repo's default branch enforces signed commits, and the agent's SSH signing key is not registered under GitHub Settings → SSH and GPG keys → SSH signing keys for the current user.

Two ways to unblock

1. Easiest: an org member with their SSH signing key registered re-runs the one-line patch:

   git checkout shai-hulud/go-hardened-install
   sed -i 's|fa8a0e1361216ec0c75e4d822f648248083e229b|0d80a856ef798b01a39f65cb88a5cf7e74e4ebf9|g' .github/workflows/go-hardened.yml
   git commit -S -am 'fix(ci): re-pin to ci-workflows-private with corrected setup-go SHA'
   git push

2. After ci-workflows-private#17 merges and tags v1, re-pin from a SHA to @v1 — at that point any unsigned-commit-tolerant collaborator can push the change.

Until either lands, the hardened-install job on this PR will fail at "Set up Go" (action SHA not found).

Companion: allora-network/ci-workflows-private#17, allora-network/skills#69.

/review-fix-loop iter-1 — blocked on token scope + signed-commits

Re-ran the review/fix loop against HEAD 132659b3. Internal 6-dim review + external review (cubic) + CI surfaced one P0: the failing hardened-install job, root-caused (as already noted above) to the SHA pin pointing at ci-workflows-private@fa8a0e1361216ec0c75e4d822f648248083e229b, which references a non-existent actions/setup-go SHA.

Update since the May 14 note: ci-workflows-private#17 merged on 2026-05-25 (merge commit e3ddce050e90ef78ceb3097404868c90bff13ded). The v1 default branch has since taken additional shellcheck-remediation commits (#27) and is currently at f2437a958b7656e660cd8d702800be1ac9381d3f. No @v1 tag has been cut yet — v1 is a branch, not a release tag.

Proposed fix (verified locally, commit fdeb3ae)

Re-pin to the current v1 branch head, f2437a958b7656e660cd8d702800be1ac9381d3f. This is immutable, includes the setup-go SHA fix from #17, and aligns with the project's SHA-pinning convention until a real @v1 tag is cut.

Why this iteration cannot push the fix

The push attempt was rejected for two independent rule violations on refs/heads/shai-hulud/go-hardened-install:

remote: - Commits must have verified signatures.
remote:     fdeb3aed4c8f31b918bd9388637ef8de3abca7b9
remote: - refusing to allow an OAuth App to create or update workflow
remote:     `.github/workflows/go-hardened.yml` without `workflow` scope

1. Signed-commits ruleset — the commit IS SSH-signed (gpg.format=ssh), but the agent's SSH signing key (~/.ssh/id_ed25519_allora.pub) is not registered under GitHub Settings → SSH and GPG keys → SSH signing keys for any user with push access on this branch. GitHub therefore marks the signature Unverified.
2. Missing workflow OAuth scope — gh auth status confirms the active token scopes are gist, read:org, repo only. The token lacks workflow, so it cannot create/update files under .github/workflows/ regardless of signature state.

Since the entire patch is a 1-line edit inside a workflow file, the standard "split-commit" workaround (push the non-workflow part first) does not apply — there is no non-workflow portion.

Maintainer hand-off

Any org member with a registered SSH signing key (or a registered GPG key) and either push permission via a token with workflow scope or a personal credential can land the fix in one command:

git checkout shai-hulud/go-hardened-install
sed -i 's|fa8a0e1361216ec0c75e4d822f648248083e229b|f2437a958b7656e660cd8d702800be1ac9381d3f|g' .github/workflows/go-hardened.yml
git commit -S -am 'fix(ci): re-pin go-install-hardened to ci-workflows-private@v1 head'
git push

After that, the hardened-install / Hardened Go install check on this PR should pass without further intervention. The other checks (test, lint, cubic) are already green.

Non-actionable secondary findings (logged, not pursued)

• P3 — paths filter on the workflow trigger does not include go.env. Editing go.env won't re-run hardened-install. Optional improvement if the team wants config drift to be CI-validated.
• P3 — repo-root go.env is not auto-loaded by the Go toolchain (which reads $GOROOT/go.env and the per-user $GOENV). The file is effectively documentation / shared developer convention. Comment header already calls out the skill reference; could optionally clarify "not auto-loaded; tooling that wants these settings must source the file explicitly."

Final state for this /review-fix-loop PR-153 worker: blocked on gh_token_missing_workflow_scope (+ secondary signed_commits_unregistered_key). No further iterations possible from inside this worker without a credential change.

Final cross-provider review (agent-code-review, 3-pass)
verdict: Ready to merge
counts: P0=0 P1=0 P2=0 P3=0
coverage: Pass 1 — correctness+security: kimi-k3 (orchestrator self-pass, substituting for Claude Opus 4.7 per user mandate); style: z-ai/glm-5.2 (substituting for Claude Sonnet 5 per user mandate). Pass 2 — correctness: google/gemini-2.5-pro; security: deepseek/deepseek-v4-pro; style: meta-llama/llama-4-maverick. Pass 3 — correctness: meta-llama/llama-4-maverick; security: z-ai/glm-5.2 (Sonnet-tier substitute); style: meta-llama/llama-4-scout. Anthropic tier not invoked via claude-code, per user-mandated substitution. All Pass 2/3 findings source-verified against the callee at the pinned SHA: 5 flagged, 5 refuted (below).

NO FINDINGS

Refuted Pass-2 findings (verification-gate rejects, not emitted as findings):

1. P1 correctness (gemini-2.5-pro): "workflow does not use the new go.env, so module-integrity settings are not applied" — refuted: the callee sets GOPROXY/GOSUMDB/GOFLAGS itself in its job-level env block (verified at 11e340a5). Repo-root go.env is developer-convention documentation by design.
2. P2 correctness (gemini-2.5-pro): "go_version: stable may diverge from go.mod's toolchain" — no concrete failing scenario; stable is the callee's declared default input, and the drift-check step pins -compat to the module's own go directive.
3. P2 security (deepseek-v4-pro): "go.env is not sourced by any workflow" — same refutation as (1).
4. P2 security (deepseek-v4-pro): "caller should pass secrets: inherit for external contributors" — refuted: same-repo pull_request runs use the base repo's token context, access to the private callee is already configured (the 2026-05-14 run evaluated and started the job), and passing secrets into a hardened audit workflow would weaken its posture.
5. P2 style (llama-4-maverick): "SHA pin inconsistent with tag-pinned actions in existing workflows" — intentional: SHA pinning is the purpose of this PR; existing tag pins are the legacy state being remediated.

Loop state: the one blocking finding this run — the fa8a0e1 pin referencing a reusable-workflow revision with a non-existent actions/setup-go SHA — was fixed and pushed in da1d6ca. During post-push verification, a separate org-level blocker surfaced: SHA-pinned callers of the private reusable workflow fail GitHub evaluation org-wide while @v1 succeeds (evidence in the needs-human thread on .github/workflows/go-hardened.yml:15). That decision is left to an org admin; the check is not required by branch protection on dev.
