docs: add multisig signing process doc, fix docs index and dead links (EXSC-711) - #2126
Conversation
WalkthroughThe pull request adds a production multisig signing process reference and updates repository documentation links, facet indexes, process links, and guide ordering. ChangesMultisig process reference
Documentation navigation updates
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The PR adds and corrects multisig process documentation without changing production behavior, but the guide still needs two bounded accuracy fixes: documenting both Safe gas conditions and accurately describing whether approval verification blocks execution. Until clarified, operators could misunderstand transaction-failure handling or the strength of an approval safeguard. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Around line 14-17: Revise the governance descriptions in
MultisigSigningProcess.md, including the direct-broadcast section and the flows
around diamondCut, pause, and unpause, so Safe multisig and timelock controller
usage are mandatory for production and never presented as bypassable. Clearly
label direct EOA, omitted-timelock, and pause paths as non-production or
explicitly authorized break-glass procedures, document their enforced guards,
and state that unpause may bypass only the delay while Safe threshold/quorum
remains mandatory.

…eak-glass (EXSC-711) Addresses CodeRabbit review on PR #2126: the doc described SEND_PROPOSALS_DIRECTLY_TO_DIAMOND, the untimelocked deployUpgradesToSAFE diamondCut, pause, and unpause without making clear that none of them weaken Safe governance on a live production diamond. Each is now scoped to bring-up/legacy/break-glass with its enforced guard named, and unpause states that only minDelay is bypassed while Safe threshold/quorum stays mandatory.

Re-verified against current main after the merge: - ensureSCCoreDevApproval.yml was retired in #2216; core-dev approval now comes from the main protection ruleset's required_reviewers rule. - CANCELLER_ROLE is held by the deployer wallet as well as the Safe, so a queued timelock operation can be cancelled without a quorum. - The Safe leg is broadcast by the deployer wallet in practice, since the signer hardware wallets are not funded on every chain. - Network count and signing threshold are no longer stated as numbers; both change over time, so the doc points at config/networks.json and at the on-chain per-Safe read instead. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…g (EXSC-711) The previous wording named config/global.json deployerWallet as a current CANCELLER_ROLE holder. That asserts live on-chain state: the role is granted at deploy time to the _cancellerWallet constructor arg and is mutable afterwards via manageTimelockCanceller, and the deployer wallet has been rotated, so the config value is not a reliable stand-in for the live holders.

State both Safe gas conditions.
EvmChainExecutor passes safeTxGas == 0 and gasPrice == 0 to execTransaction. State both conditions because Safe reverts a failed inner call only when both values are zero; otherwise it emits ExecutionFailure after consuming the nonce.

Fixes EXSC-711
Why did I implement it this way?
The repo documents contracts thoroughly but the processes around them — how a change gets deployed, audited, proposed to the multisig, signed and executed — live in people's heads, in Slack threads, and partially in
.agents/commands/multisig-rollout.md. This addsdocs/MultisigSigningProcess.mddescribing the process as it exists today, not as we would like it to be. Everything in it was verified against the code onmain; it cites script paths and function names rather than line numbers, which rot.The check table carries an explicit "Enforced by" column mapping each rule to the script or workflow that enforces it. That was deliberate: it makes the difference between "we have a convention" and "the system enforces a convention" visible at a glance, and it makes gaps obvious rather than implicit.
There is an honest section on what the signer still has to verify manually. It would have been easy to write a doc that implies the tooling covers more than it does; that would be worse than no doc.
Housekeeping included because it is the same edit surface:
docs/README.mdwas missing several process docs that already exist, and the rootREADME.mdlinked./conventions.md— a file that no longer exists — in four separate places, now pointed at.agents/rules/.A short "planned improvements" section at the end is clearly marked as proposal-stage and not yet implemented, so the doc does not read as describing features we do not have.
The
deployUpgradesToSAFEpre-proposal gate is described as retargeted in PR #2128 / EXSC-687 (production: matchorigin/mainor open-PR + audit-log freeze; staging ungated). The previous draft said that path required GitHub SC + auditor reviews, which would have blocked the usual feature-branch rollout of already-merged code. That gate still applies only to that one entry point, not tosendOrPropose/ timelock-wrapped cuts.Stacked on #2128. This doc describes the
deployUpgradesToSAFEgate as retargeted by #2128, so it must not reachmainfirst — otherwisemainwould carry a doc asserting a gate that does not exist yet, which contradicts the doc's own "documents what is" premise. Basing this PR on that branch makes the ordering structural rather than a thing reviewers have to remember; GitHub retargets this tomainautomatically once #2128 merges. Note that CodeRabbit does not auto-review a non-default base and still reports its check green, so its review was triggered manually.Merged current
main(cccf9b7) into the branch. One conflict, indocs/README.md, where this branch's added entries overlapped main's removal of the deprecated Hop docs (#2219). Resolved as a union with the Hop entries left deleted — a naive union would have silently resurrected doc links to deprecated facets. Verified afterwards that noHopFacetreference survives, that main'sDeploymentLogs.mdentry does, and that every./*.mdlink in the index resolves to a real file.FraxFacet.md, added by main and missing from the index, was added too — the same defect class this PR exists to fix.Re-verifying the doc against the merged
mainturned up four claims that had gone stale or were wrong, all now corrected:ensureSCCoreDevApproval.ymlis no longer a live gate — retired in chore(ci): retire flaky SC core-dev approval workflow (DO-728) #2216. Core-dev approval now comes from themain protectionruleset'srequired_reviewersrule on thesmart-contract-coreteam, confirmed via the API.LiFiTimelockController's constructor additionally grants it to_cancellerWallet(deployerWallet), which is a distinct address from every Safe. A queued operation can therefore be cancelled without a quorum, which is worth stating plainly in a signing doc.confirm-safe-tx.tsoffersSign and Execute With Deployer/Execute with Deployer, which broadcast withPRIVATE_KEY_PRODUCTION. The roles table and the §4.3 action-prompt list now say so.config/networks.jsonas the live list, and notes the threshold is read on-chain per Safe at confirm time.Governance impact (rule 105): documentation only. No change to any script, workflow, Safe threshold, timelock delay, role, or transaction authorization path.
