Which Linear task belongs to this PR?

Fixes EXSC-687

Why did I implement it this way?

The original gate assumed every feature-branch Safe upgrade was shipping new Solidity from that PR, so it required the facet file to be in the PR plus GitHub SC and auditor reviews. Our usual process is the opposite: branch off main, deploy already-merged code, and keep the facet sources unchanged — so that check would have blocked the default rollout path as soon as it actually failed closed. Production now allows main unconditionally, and allows any other branch when each selected src/Facets/<Name>.sol matches origin/main (working tree included). Only when a selected facet diverges does the exception path run: an open PR, an audit/auditLog.json entry for the current @custom:version with a real commit hash, and a working tree that still equals that audited commit. Staging is not gated. The shell still stops on a non-zero exit, so a failed lookup cannot proceed.

Checklist before requesting a review

Checklist for reviewer (DO NOT DEPLOY and contracts BEFORE CHECKING THIS!!!)

  • I have checked that any arbitrary calls to external contracts are validated and or restricted
  • I have checked that any privileged calls (i.e. storage modifications) are validated and or restricted
  • I have ensured that any new contracts have had AT A MINIMUM 1 preliminary audit conducted on by <company/auditor>

verify-approvals.ts printed the "OK" marker unconditionally, so
deployUpgradesToSAFE.sh - which compared that marker - continued even
after the check had logged failures. The script now exits non-zero on
any failure and prints the marker only on the fully successful path,
and the shell caller gates on the exit code instead.

Also paginates the GitHub list calls (listFiles capped at 30 entries,
producing false "facet is not included in this PR" results), turns the
swallowed helper errors into throws so a failed lookup can no longer
read as an empty result, and requires GH_TOKEN up front (now documented
in .env.example).

Walkthrough

The PR replaces Octokit-based approval checks with a deploy gate based on environment, branch, transitive Solidity source comparison, audit commits, and open pull requests. It updates Safe deployment wiring, removes Octokit, uses Node.js file reads, and expands test coverage.

Changes

Production deploy gate

Layer / File(s) Summary
Deploy-gate policy and source validation
script/deploy/github/verify-approvals.ts, script/deploy/github/verify-approvals.test.ts
The verifier compares each facet's transitive src/ import closure with main. Diverged facets require an open pull request and a valid, available audit commit with no later changes.
Audit references and GitHub CLI integration
script/deploy/github/verify-approvals.ts, script/deploy/github/verify-approvals.test.ts, package.json
The audit log is read from the main ref. Open pull requests are counted through gh pr list. Octokit and explicit token handling are removed.
Verifier runtime and CLI contract
script/deploy/github/verify-approvals.ts, script/deploy/shared/getContractVersion.ts, script/deploy/github/verify-approvals.test.ts
The CLI accepts environment, branch, and facets. It reports OK\n on success and uses Node.js readFile for Solidity source reads.
Safe deployment gate wiring
script/deploy/deployUpgradesToSAFE.sh, script/deploy/github/verify-approvals.test.ts
The shell gate runs for every environment except staging and aborts when verification fails. Tests cover production, unknown, empty, and staging environments.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to 2c3a3

The production deployment gate can approve a locally identified main checkout without confirming it matches the canonical main branch, and it does not verify external Solidity libraries that can change the deployed bytecode. These gaps could allow unaudited code into a production Safe proposal, so the PR is not merge-ready until the source-integrity checks cover both cases.

99-108: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Filter open pull requests with the head parameter

GitHub’s list-pulls endpoint accepts head in owner:branch form, so this can request only PRs on the target branch instead of paginating every open pull request and filtering client-side. This reduces deploy-list network traffic as the repo accumulates more open PRs.

♻️ Proposed fix
 const getOpenPRsForBranch = async (octokit: Octokit, branch: string) => {
   const pullRequests = await octokit.paginate(octokit.rest.pulls.list, {
     owner: OWNER,
     repo: REPO,
     state: 'open',
+    head: `${OWNER}:${branch}`,
     per_page: PER_PAGE,
   })

Usual feature-branch rollouts match main and must not be blocked. Staging stays ungated. A production deploy whose facet sources diverge from main still requires an open PR and an unchanged audited commit.

…SC-687)

deployUpgradesToSAFE.sh runs the gate with `bunx tsx`, i.e. under Node, but
getContractVersion read sources through Bun.file. That global is undefined
outside bun and the per-path catch swallowed the ReferenceError, so every
version lookup failed. Any facet diverging from main was rejected with
"Could not find version" instead of being compared against its audited commit,
which made the audit-freeze exception path unreachable.

Reading through node:fs/promises keeps the helper working under both runtimes
and leaves the `bunx tsx` invocation that 200-typescript mandates in place.
The existing tests could not catch this: they inject getContractVersion through
IDeployGateDeps, and the CLI tests spawn process.execPath, which is bun under
`bun test`. Added a test that exercises the real helper through bunx tsx.

Also corrected the GH_TOKEN documentation, which still described the previous
implementation's GitHub calls and scopes, and dropped comments that narrate the
code per 000-global-standards.
…of argv (EXSC-687)

An environment string that was neither production nor staging returned "no
failures", so a typo such as `--environment prod` allowed a diverged facet
through. Only staging short-circuits now; anything unrecognised is a failure.

The token moves from a CLI flag to the child's environment so it is no longer
visible in the process table for the life of the call, and the success marker
is newline-terminated so it stops running into the next line of output.

/gate-review — escalated findings

Auto-fixed in e04dd303a / 75efbebbd (details in the commit messages): the bunx tsx vs Bun.file runtime break, the fail-open on an unrecognised --environment, the PAT in argv, the stale GH_TOKEN docs, and comment-discipline cleanups.

The items below were not changed — they alter production-gate policy and need a decision. None of them is a regression from this PR: the previous gate wrote OK unconditionally and never blocked anything, so this PR is a strict improvement. My recommendation is to ship as-is and take 1–3 as a follow-up ticket.

1. The gate compares only src/Facets/<Name>.sol, not the facet's import closure

A facet's bytecode embeds src/Libraries/*, src/Helpers/*, src/Errors/*, plus foundry.toml / remappings.txt / lib/ submodule SHAs. AcrossFacetV4.sol alone imports 8 local files. A branch that changes LibAsset.sol while leaving every facet file byte-identical passes with no PR and no audit, and the cut then proposes materially different bytecode. Options: walk the import closure, or compare forge inspect <Facet> bytecode against a temp worktree at origin/main.

2. resolveMainRef never fetches → fail-open on a stale origin/main

If a colleague merges a fix to FacetX and your local origin/main predates it, your older FacetX compares equal to the stale ref and is allowed — silently reverting merged, reviewed code. The local-main fallback is worse. A git fetch --no-tags origin main before resolving fixes it, but adds a network dependency that can fail the deploy offline — hence escalated rather than applied.

3. 67 of 200 audit-log entries point at commits that are not in a full clone

Measured on this checkout (4515 commits, non-shallow): audit commits generally live on squash-merged, since-deleted PR branches. git show <hash>:<path> then fails, and fileMatchesRef returns false, which is rendered as "<Facet> has changed since audited commit <hash>" — an assertion about content that was never read. The exception path is therefore unusable about a third of the time, with a message that is factually false. Suggested: probe git cat-file -e <hash>^{commit} first, try git fetch origin <hash>, and emit a distinct "audited commit not available locally" failure.

4. CoreFacets cannot be deployed from a feature branch

gum choose offers every Update*.s.sol. UpdateCoreFacets.s.sol is the only one with no matching src/Facets/<Name>.sol (verified post-merge, it is the sole case). It is an alias for the 12 facets in config/global.jsoncoreFacets. Today it aborts the run with Could not find version for CoreFacets. It fails closed, so nothing unsafe ships — but a production CoreFacets update from a branch is impossible and the operator gets no usable diagnosis. Options: expand the alias via getCoreFacets(), or emit a per-facet failure instead of throwing (which would also stop one bad name from aborting evaluation of the others).

5. fileMatchesRef collapses "unreadable" and "different"

A facet that is new on the branch, a missing git binary, and a genuine source change are indistinguishable. It fails closed in every path I traced, so this is a diagnosis defect rather than a hole — but it is how gates get disabled by operators. A tri-state (match | differs | unreadable) with its own message would fix it.

6. hasOpenPr accepts any open PR, including a draft against any base

No filter on draft === false or base.ref === 'main', so the "has an open PR" half of the exception is weaker than the docstring's "under review" implies. Low impact because the audit-freeze half runs alongside.

Lower confidence — human judgement

  • Audit-array ordering: the code takes the last valid entry. Across the 29 multi-audit entries, 0 are out of chronological order today, so "last == latest" holds — but nothing sorts or validates it.
  • Test coverage: everything that shells out to git, reads the audit log, or calls GitHub is exercised only through injected deps. Findings 1–5 all live in that uncovered region. A scratch-repo integration test (git init → commit a facet → branch → mutate) driving createDefaultDeps would cover it, plus a table-driven test asserting every Update*.s.sol name resolves to a source with a @custom:version — that one test catches CoreFacets and any future rename.

Comment thread script/deploy/deployUpgradesToSAFE.sh Outdated
getFileSuffix maps anything other than "production" to the staging suffix, but
getPrivateKey only treats *staging* as staging and hands the production key to
every other value. An accepted typo such as ENVIRONMENT=prod therefore skipped
the gate entirely - the shell tested for "production" - and still proposed to
the Safe with the production key. Rejecting the value inside the verifier does
not help when the verifier is never invoked.

The gate now runs for every environment that is not exactly staging, so an
unrecognised value reaches the verifier and is rejected there.

Reported by CodeRabbit on the deployUpgradesToSAFE.sh gate condition.
The gate made exactly one GitHub call - listing the open PRs for a branch - and
required every SC dev to create and store a personal access token for it. gh is
already installed and authenticated on those machines, so the CLI does the same
lookup with no credential to provision, rotate, or keep out of the process table.

Drops GH_TOKEN from .env.example (now identical to main again), the --token flag,
the token plumbing through createDefaultDeps, and the @octokit/rest dependency,
which this file was the only consumer of.

The CLI is only ever invoked from deployUpgradesToSAFE.sh, an interactive local
deploy, so it never runs anywhere gh is unavailable. A missing or unauthenticated
gh throws, which the shell still reads as a blocked deploy.

🔍 QA Review — EXSC-687 — S1 · Make the deployment approval gate actually block

PR: #2128 | Ticket: EXSC-687 | Review type: 🆕 First review | Date: 2026-08-28


What this PR does

Rewrites the production Safe upgrade gate in script/deploy/deployUpgradesToSAFE.sh and its TypeScript verifier script/deploy/github/verify-approvals.ts. The original code wrote an OK marker even after logging failures, and the shell gate had no else branch, so deploys continued regardless. The fix closes the fail-open in both layers, corrects the deploy policy to match the actual branch workflow (deploy from any branch, not just PR branches), and introduces a 427-line test suite covering all policy paths. A critical environment-bypass discovered by CodeRabbit — where ENVIRONMENT=prod skipped the gate entirely but still reached the production key — was also fixed in commit 71c2c5c.


Acceptance Criteria Check

# Criterion Status Evidence
AC1 Gate is fail-closed: failed checks abort the deploy ✅ Pass if ! bunx tsx ... verify-approvals.ts ...; then error "..."; return 1; fi in deployUpgradesToSAFE.sh. Old code had no else; new code uses exit-code check and returns 1. reportApprovalResult exits TypeScript process with code 1 on any failure.
AC2 On main: deploy allowed without checks ✅ Pass verifyDeployGate returns early (return []) when input.branch === 'main'. CLI integration test confirms main exits 0 without touching repo or GitHub.
AC3 Feature branch: each selected src/Facets/<Name>.sol must match origin/main ✅ Pass verifyDeployGate iterates all facets, calls deps.fileMatchesRef(deps.mainRef, path) per facet (path = src/Facets/${name}.sol). Compares working copy byte-for-byte against git show origin/main:<path>.
AC4 Exception path: open PR + audit log entry with real 40-char hash + no changes since audited commit ✅ Pass For diverged facets: getOpenPrCount called; resolveAuditCommitHash validates against AUDIT_COMMIT_RE = /^[0-9a-f]{40}$/i (skips n/a); fileMatchesRef(auditCommitHash, path) verifies no changes since that commit. All three must pass.
AC5 GitHub list calls paginate (no 30-file cap) ✅ Pass (note) Uses gh pr list --limit 100 via GitHub CLI. @octokit/rest dependency removed entirely. Eliminates practical cap (no single branch can have 100 open PRs).
AC6 GH_TOKEN only required on exception path; fail loudly if absent ✅ Pass countOpenPRsForBranch uses gh CLI, reached only when a facet diverges from main. If gh unauthenticated, execFileSync throws, propagating as non-zero exit. No GH_TOKEN env var required.
AC7 Staging is NOT gated ✅ Pass collectDeployGateFailures returns empty list immediately when environment === EnvironmentEnum.staging. Shell gate: if [[ "$ENVIRONMENT" != "staging" ]].
AC8 Lookup errors throw (not silently pass) ✅ Pass resolveMainRef throws if origin/main/main not found. loadAuditLog throws on missing/invalid JSON. countOpenPRsForBranch re-throws with descriptive message. getContractVersion throws on no match.

Code Analysis

Fail-closed mechanism (deployUpgradesToSAFE.sh)

Old code: VERIFIED=$(verifier...) then if [[ $VERIFIED == "OK" ]] with no else — any non-OK output (including empty string from crash) caused silent fallthrough. New: if ! bunx tsx ./script/deploy/github/verify-approvals.ts ...; then return 1; fi. No string parsing.

Environment bypass fix (commit 71c2c5c) — most critical finding in review

Original gate used if [[ $GIT_BRANCH == "main" ]] (wrong axis). getPrivateKey internally treats only *staging* as staging, falling through to production key for everything else — so ENVIRONMENT=prod skipped the gate while still reaching the production Safe with the production private key. Fix: if [[ "$ENVIRONMENT" != "staging" ]] — every non-staging value goes through the verifier, where unrecognised values (e.g. prod) are explicitly rejected.

Policy correctness (verify-approvals.ts)

Pure policy logic in collectDeployGateFailures, testable via dependency injection (IDeployGateDeps). Lazy evaluation ensures staging/main never shells out. fileMatchesRef returns false for files missing at origin/main (new facets) — fail-safe, requiring the full exception path for new Solidity.

getContractVersion.ts change

Bun.file().text()readFile(fullPath, 'utf8') from node:fs/promises. Makes function work under tsx runtime. Path-traversal guard unchanged.

Open (non-blocking) — nitpick

CodeRabbit Aug 28 nitpick at verify-approvals.test.ts line 367 (.then() vs top-level await in a generated probe string literal) is unaddressed. In a string passed to writeFileSync (a temporary file's content), not the test body itself — no functional impact.

reportApprovalResult OK\n to stdout on success; exit(1) on failure
verifyDeployGate No GitHub/audit calls when facets match main; selective for diverged facets
verify-approvals CLI Subprocess: staging/main exits 0 without hitting GitHub

deployUpgradesToSAFE gate condition Live regression guard: reads actual .sh at test time, runs bash -c for production, prod, "", staging — catches the bypass class
open-PR lookup Asserts 'gh' used, not Octokit/GH_TOKEN

One gap: no test for fileMatchesRef → undefined (missing working copy/main ref), though fail-safe direction makes it low risk.


Ticket Coverage

Full. All eight AC items addressed. PR additionally fixes the ENVIRONMENT=prod bypass (not in ticket, but directly in scope of "gate must not fail open"). Three rounds of CodeRabbit feedback addressed — final Aug 28 nitpick trivial, non-blocking.


Downstream Impact

  • No Solidity changes. AuditNotRequired label appropriate; no @custom:version bump needed.
  • @octokit/rest removed from package.json. No other consumer in repo.
  • gh CLI required for exception path. Must be installed and authenticated on developer machines (already standard).
  • Staging deploys unaffected. Gate runs only for non-staging environments.

✅ Verdict: Pass

The gate is now genuinely fail-closed. The critical ENVIRONMENT=prod bypass — where a typo could have skipped the verifier while reaching the production Safe — is fixed. The 427-line test suite includes a live shell-condition test that would catch the same bypass class in future. The one open nitpick has no functional impact.

Both gaps let a production deploy pass the gate while carrying code no
reviewer had seen.

The gate compared only src/Facets/<Name>.sol against main, but a facet
compiles its libraries and helpers in, so an edited LibSwap.sol changed
the deployed bytecode while the facet file still matched main and the
deploy proceeded with no PR and no audit. Each facet is now compared
through its transitive src/ import closure, resolved from relative and
lifi/-remapped specifiers.

The audit log was read from the working tree while every facet
comparison read from a git ref, so the divergence exception was
self-certifiable: a local commit plus a fabricated auditLog.json entry
naming its SHA satisfied the freeze check. It is now read via
git show <mainRef>:audit/auditLog.json, so the entry has to be merged.

An audited commit that is missing from the checkout is now reported as
such instead of surfacing as every closure file having changed.

Auto-fixed: nothing beyond the two review fixes themselves (both verified on real repo data, evidence in the two threads above).

Escalated — needs a decision, not auto-fixed

1. resolveMainRef falls back to a local mainscript/deploy/github/verify-approvals.ts

origin/main is tried first and wins on any checkout with a remote, so this is not reachable in a normal deploy. But where it is reachable, the ref the gate trusts is fully operator-controlled, and after this PR that ref also supplies the audit log — the same property Goran's finding was about. Not auto-fixed because dropping the fallback would make the gate hard-require origin/main and that changes behaviour for local runs.

2. The gate never fetchesscript/deploy/deployUpgradesToSAFE.sh:39

GIT_BRANCH=$(git branch --show-current) and the gate call are not preceded by a git fetch, so origin/main is whatever was last fetched. A stale remote-tracking ref means "matches main" can pass against a main that has since moved, and the audit log is now read from that same possibly-stale ref. Not auto-fixed because adding a network call to a deploy script is an externally observable behaviour change.

Worth stating plainly for both: a git-based gate is not forgery-proof against an operator with local git access — git update-ref refs/remotes/origin/main is as available as editing a JSON file. What this PR changes is the bar, from "edit an untracked working-tree file" to "rewrite a remote-tracking ref", and it removes the accidental-bypass case entirely. If the threat model needs more than that, the check has to move server-side (CI) rather than run on the deploying machine.

Parse the GitHub CLI output inside the guarded block.

JSON.parse(stdout) runs outside the try. If gh prints unparsable output, the operator sees a raw SyntaxError instead of the descriptive message that the JSDoc promises for "unusable output".

Anchor the extracted gate condition to the verifier invocation.

.find() returns the first line that contains $ENVIRONMENT and if [[. Today only the gate line matches. If another $ENVIRONMENT condition is added earlier in deployUpgradesToSAFE.sh, this test would assert the run/skip decision of an unrelated condition and still pass while the deploy gate regresses.

Match the block that guards the verify-approvals.ts call, for example by locating the verify-approvals.ts line first and taking the closest preceding if [[ line.
