fix(safe): acknowledge changes instead of replaying actions across networks (EXSC-702)#22850xDEnYO wants to merge 5 commits into
Conversation
The confirmation loop cached the chosen action keyed by calldata alone, so a "Sign & Execute" answered on one network was replayed verbatim on every later network whose calldata matched byte-for-byte — up to 71 of them, with no prompt. Actions are no longer remembered at all. What rolls up instead is an acknowledgement of the reviewed change, fingerprinted on keccak of the full calldata so per-network init payloads stay distinct, and recorded against a per-proposal key that carries to + chainId + nonce. A proposal whose checks failed is never acknowledged, and a prior acknowledgement never suppresses the prompt on one that fails. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The roll-up only saw proposals an action was taken on, so a run where some networks were skipped reported a denominator smaller than the fleet. A provisional entry is now recorded before the prompts and superseded by the final one, which the per-proposal-key dedup already supported. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
WalkthroughThe Safe confirmation flow now fingerprints calldata, validates nonce integrity, records acknowledgements per proposal, aggregates network outcomes, and renders a change summary. New Bun tests cover the helper module, integration behavior, roll-ups, and removal of cached action responses. ChangesSafe transaction acknowledgement flow
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The change stops replaying signing actions and keeps action selection per proposal, but an acknowledgement can still be reused for a different transaction when calldata matches, allowing signing or execution without freshly acknowledging the exact proposal. Rollout summaries can also omit networks or show failed checks as acknowledged, so these current-head issues should be fixed before merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Line 306: Update the assertion around the ledger check to inspect the ledger
structure directly rather than using JSON.stringify(ledger). Specifically,
examine the entries or values of acknowledgedProposalKeys and assert that none
contains the Execute action, while preserving the existing intent of rejecting
stored Execute entries.
In `@script/deploy/safe/confirm-safe-tx-ack.ts`:
- Line 184: Change outcome aggregation so the latest INetworkOutcome globally
supersedes earlier outcomes by proposalKey, regardless of calldata fingerprint.
First collect outcomes in a Map keyed by proposalKey, then group only the
surviving outcomes by fingerprint before producing the summary; add a regression
test covering one proposal key with two fingerprints.
In `@script/deploy/safe/confirm-safe-tx.ts`:
- Around line 449-455: Update main and the networkOutcomes flow so every pending
network receives an explicit skipped outcome before the roll-up is rendered,
including not-owner, owner-check-failed, nothing-actionable, and early-return
paths. Preserve processTxs outcomes for actionable networks and ensure the
summary still renders when no network is actionable.
- Line 639: Update the acknowledgement summary to use the boolean result
returned by recordAcknowledgement instead of always setting acknowledged to
true, preserving the ledger’s rejection status when integrity.ok is false.

…counts Review-gate findings on the first two commits. The acknowledgement was keyed on the payload alone, so identical bytes aimed at a different target, sent as a DelegateCall, or carrying value inherited a review earned elsewhere. There are 31 distinct LiFiDiamond addresses across the 71 active networks, so the target genuinely varies. The key is now target + value + operation + payload fingerprint; networks sharing a target still collapse to one acknowledgement. The roll-up's tick meant only "no stale nonce", so a run where 70 of 71 networks were skipped rendered green. The fields now say what they measure - nonce usable and reviewed - and the tick needs both at N/N. The anti-regression guard was three negative greps for the deleted identifier, which a nullish coalesce, an if/else, a ternary or a Map.set all evade while restoring the replay. It is now positive-form: every assignment to `action` must be the prompt itself. Verified firing on all four reintroductions. The test compared two deployed addresses across deployment files, which are outside the unit-test workflow's path filter, so a routine redeploy would have broken it in an unrelated PR. It reads constants now. The review summary moved into the finally block - an aborted run is where the ledger matters most. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

|---|---|---|
| F2 | Acknowledgement keyed on the payload alone. Identical bytes aimed at a different target, sent as DelegateCall, or carrying value inherited a review earned elsewhere. operation, value, to and data are all members of the signed EIP-712 struct; the key covered one of four. Confirmed on real data: 31 distinct LiFiDiamond addresses across the 71 active networks, so the target genuinely varies. |
Key is now keccak(to, value, operation, fingerprint). Networks sharing a target still collapse to one acknowledgement. |
| F3 | The roll-up's ✓ meant only "no stale nonce". A 71-network run where the operator chose Do Nothing on 70 of them rendered green. |
Fields renamed to what they measure (noncesUsable, acknowledged); the tick requires both at N/N. Demo below. |
| F1 | The three anti-regression tests were negative greps for the deleted identifier. A nullish coalesce, an if/else, a ternary or a Map.set each restore the full cross-network replay while passing all three. |
Positive-form: every assignment to action must be the prompt itself. Verified firing on all four reintroductions — output below. |
| F4 | The test asserted two deployed addresses were equal across deployments/*.json. Those files are not in ts-unit-tests.yml's path filter, so a routine redeploy PR would merge green and detonate the test in whichever unrelated PR next touched script/**. |
Reads constants; no cross-file address assertion. |
| F5 | ProposalIntegrityFailure / "checks failed" read as the repo's safety checks generally. It is one bit: nonceStatus === 'stale', and it only reaches the gate via a bare Sign — every execute-shaped action on a stale nonce is already terminated earlier. |
Renamed and documented, including the reachability constraint. |
| F6 | expect(rendered).not.toContain('✓') held only because the fixture had one change; a real multi-change run contains both glyphs. |
Asserts the specific line startsWith('✗'). |
| F8 | The review summary sat after the network loop, so a mid-run throw printed no ledger — the case where it matters most. |
Moved into finally. |

Not fixed — carried forward deliberately
- Decode failure cannot reach the nonce verdict.
formatDecodedTxDataForDisplayreturnsPromise<void>and swallows decode failures, so an undecodable payload — the case where an acknowledgement is least earned — produces no machine-readable signal. Changing that helper's contract is outside this PR; filed as follow-up. - The acknowledgement roll-up shrinks from 71 networks to per-target groups (26 on
0x1231DEB6…, 7 on0x026F2520…, etc.). That is the intended consequence of the F2 fix, and it refines the "collapses to one" wording in the Signing 2.0 acceptance row A0.1(d) to "one per distinct target". Flagging it because it touches an approved acceptance criterion. - The action prompt is now unconditional per network — by design (that is the bug), but it is a real ergonomics cost: a 71-network byte-identical rollout goes from 1 action prompt to 71.
storedResponseswas introduced in chore: reuse and retry when confirming #673 specifically to collapse those.
The PR body's "Falsification" section has been corrected: the origin/main run demonstrates the greps detect the deleted text, which is not the same as demonstrating the guard resists reintroduction. The four-variant table above is the actual evidence.

…ving failures Round-2 review-gate findings on 733a004. The guard fired on seven benign edits - a comment mentioning "action =", a reworded prompt label, a type assertion - while six real reintroductions slipped past it, including reassigning consola.prompt to a caching shim at module scope and a replay branch that acts and continues before `action` is assigned. It now strips comments and string literals before matching, matches the prompt call without pinning its label, and separately forbids reassigning consola.prompt. Its comment states what it cannot catch instead of implying completeness. The review summary could be the only thing printed on an aborted run, marker and all, because the execution summary was still inside the try. Both now print together at the end of finally, after the transport close so a write failure cannot leave the Ledger open, and the review block says so when executions failed. The acknowledgement key now reads the normalised transaction rather than the stored document, so it describes the struct that gets signed. An empty value string is rejected instead of keying as zero. Two unreachable fallbacks in the roll-up are gone, and the test no longer reads deployments/ - that path is outside the unit-test workflow's filter, so a redeploy would have broken it in an unrelated PR.

…ominator CodeRabbit findings on eeb8975. The summary reported acknowledged: true even when recordAcknowledgement had refused to store it, so a proposal with a consumed nonce could read as reviewed. It now reports the ledger's answer. processTxs only runs for networks with actionable proposals, so a per-change N/N counts covered networks rather than the fleet - not-owner, owner-check-failed and nothing-actionable contribute none. Those networks have no payload to build a key from, so rather than synthesise outcomes the run now states the coverage explicitly whenever it is short. Superseding a provisional outcome is scoped to one effect group, which the caller satisfies by reusing one key per proposal. Written down rather than left implicit.

| # | Finding | Disposition |
|---|---|---|
confirm-safe-tx.ts:652 · 🟠 Major |
recordAcknowledgement returns false when the nonce check failed, but the outcome always said acknowledged: true |
FIXED. The summary now reports what the ledger accepted, not that the operator answered. A consumed-nonce proposal can no longer read as reviewed. |
confirm-safe-tx.ts:467 · 🗄️ Major |
networkOutcomes is only populated inside processTxs, which runs only for networks with actionable proposals — not-owner, owner-check-failed and nothing-actionable contribute nothing, so a per-change N/N is not fleet coverage |
FIXED, differently than suggested. Those networks have no payload, so no acknowledgement key can be built for them; synthesising outcomes would have put made-up entries in a security summary. The run now states the coverage whenever it is short: "Covers N of M networks attempted — the rest produced no reviewable proposal (not an owner, ownership read failed, or nothing actionable). Per-change counts below are out of the covered networks, not the fleet." Truthful without inventing data. |
confirm-safe-tx-ack.test.ts:306 · 🟡 Minor |
JSON.stringify(ledger) serialises a Map as {}, so the "stores no action" assertion was vacuous |
ALREADY FIXED in bd1158e24 — the test dumps the Map entries explicitly. Correct finding, and it was a genuinely vacuous assertion. |
confirm-safe-tx-ack.ts:250 · 🟡 Minor |
superseding is scoped per effect group, so a provisional and final outcome with the same proposalKey but different keys would be counted twice |
DOCUMENTED, not code-changed. Unreachable through the only caller: processTxs computes acknowledgementKey once per proposal as a const and reuses it for both pushes. Changing the grouping to dedupe globally by proposalKey would alter the roll-up semantics to fix a state the caller cannot produce. The caller contract is now written down in the JSDoc instead. |
bun test script/ — 1122 pass / 0 fail. eslint and tsc-files clean on all three files.
CI was fully green on bd1158e24 before this push; re-running now.

Why did I implement it this way?
confirm-safe-tx.tscached the operator's chosen action keyed by calldata alone(
storedResponses[tx.safeTx.data.data] = action) in module-level state shared across every networkin a run. So a
Sign & Executeanswered once was replayed verbatim, with no prompt, on everylater network whose calldata matched byte-for-byte — up to 71 of them. Sign-and-execute is not a
preference worth remembering; it is a decision that must be made per proposal.
The action is now never remembered. What rolls up instead is an acknowledgement of the reviewed
change, so a fleet-wide rollout is reviewed once and answered N times:
keccak256(full calldata), not afacet+version+selectorslabel. Asemantic label collapses per-network init payloads into one change — exactly the fleet-wide
blindness this fix is meant to close.
keccak(to, value, operation, fingerprint).All four are members of the signed Safe struct, and keying on the payload alone would let identical
bytes aimed at a different target — or sent as a
DelegateCall, or carrying value — inherit areview earned elsewhere. There are 31 distinct
LiFiDiamondaddresses across the 71 activenetworks, so the target genuinely varies. Networks that share a target still collapse to one

Falsification
The loop is interactive and has no injectable seam, so the guard against reintroducing the replay
reads the source. It is positive-form — every assignment to
actionmust be the prompt itself —because a negative grep for the deleted identifier only catches a byte-for-byte revert. Run against
the real pre-fix file and against four reintroductions that each restore the full cross-network
replay:
V1–V3 all pass a naive
