📝 WalkthroughWalkthroughAdds a deterministic timelock rehearsal for scheduling, cancellation, rescheduling, and delayed execution. Adds permissionless execution for matured operations, Base fork tests, workflow dispatch options, and timelock documentation. ChangesTimelock rehearsal flow
Estimated code review effort: 4 (Complex) | ~45 minutes Mergeability Score: 🟡 Moderate · up to This PR adds a timelock rehearsal and execution flow, but the current implementation can schedule and execute different operation ids, report an executor-role failure only after a transaction has already been sent, and leave fork tests failing permanently after the fixed-salt rehearsal runs on Base. These issues should be addressed before merging. Possibly related PRs

The ExecutionNotPermissionless guard is unreachable.
LibTimelockInvariants.assertTimelockState already asserts the open executor role. src/lib/LibTimelockInvariants.sol Lines 297-298 call _assertHasRole(acl, timelock, TIMELOCK_EXECUTOR_ROLE, address(0)). That call reverts at Line 81 before Line 84 runs, so ExecutionNotPermissionless can never be raised and the error declaration at Line 29 is dead.
Either drop the duplicate check and the error, or reorder so the named check runs before assertTimelockState.

Check the executor's roles before broadcasting.
The require at Lines 109-112 runs after vm.stopBroadcast(). If the executing key did hold EXECUTOR_ROLE, the transaction is already sent and the operation is already Done. The revert then fails the CI job without undoing anything, and the operator must reconstruct what happened from logs. Move the role check above vm.startBroadcast() so the script refuses to broadcast instead of reporting the violation afterwards.

The rehearsal operation parameters are declared twice. REHEARSAL_SALT and rehearsalPayload() exist independently in both scripts. Both are internal, so no test can compare them directly, and the two scripts must agree on the derived operation id or the executor cannot execute what the rehearsal scheduled. Declare them once and import them.

Document that a real execution retires REHEARSAL_SALT permanently.
REHEARSAL_SALT is fixed, so the operation id is fixed. OZ's _schedule reverts when isOperation(id) is true, and a Done operation keeps isOperation(id) == true forever. After 20260813-execute-timelock-operations executes the rehearsal on chain, run() and reschedule() revert with RehearsalAlreadyScheduled and the rehearsal cannot be repeated. The guard is correct, but the operator needs to know that repeating the rehearsal requires a new salt.
Add that constraint to the contract docs, or derive the salt from an operator-supplied counter.

Correct the doc comment: the helper derives the id, it does not read an artifact.
The comment states that the function reads the operation id out of an emitted artifact. rehearsalOperationId calls hashOperation and never touches a file. The comment also states that the test does not restate the operation shape, but Lines 48-52 restate the target, value, payload, predecessor, and salt.

Assert value and operation on the authored transaction.

These fork tests break permanently once the rehearsal runs on Base.
The fork is unpinned head and the salt is fixed, so the operation id is fixed on Base forever. Two consequences follow.
If an operator schedules the rehearsal and leaves it pending, testCancelRefusesWhenNothingScheduled fails, because the precondition "nothing is scheduled" no longer holds against head.
After 20260813-execute-timelock-operations executes the rehearsal on Base, the timelock keeps isOperation(id) == true for the Done operation. TimelockRehearsal._authorSchedule then reverts with RehearsalAlreadyScheduled, so testScheduleAuthorsABundle, testRehearsalIsANoOp, testScheduleCancelReschedule, and testScheduleRefusesWhenAlreadyScheduled all fail. The PR exists to perform that execution, so this is a scheduled CI break rather than a hypothetical one.
Gate the state-dependent tests on the live operation state, in the same way that test/script/20260804-deploy-deterministic-v4-authoriser-clone.t.sol gates testRunRejectsUninitializedCloneAtTarget on the target having no code.
🛡️ Proposed guard pattern
function testCancelRefusesWhenNothingScheduled() external {
+ vm.skip(timelock().isOperation(rehearsalOperationId()));
vm.expectRevert(abi.encodeWithSelector(RehearsalNotScheduled.selector, rehearsalOperationId()));
rehearsal.cancel();
}Apply an equivalent skip to every test that calls rehearsal.run() or rehearsal.reschedule(). Alternatively, derive the salt so each rehearsal round uses a fresh id, which removes the one-shot constraint from both the script and the tests.
Based on learnings, state-dependent fork tests in this repository must run only when the live precondition holds: "testRunRejectsUninitializedCloneAtTarget must run only when LibProdDeployV4.STOX_PROD_AUTHORISER_V4_CLONE_DETERMINISTIC has no code."
