fix(deploy): detect facet removals that never executed (EXSC-774)#22010xDEnYO wants to merge 2 commits into
Conversation
A facet removal recorded as done could stay invisible indefinitely. On worldchain the parked AcrossFacetV3 task was marked `executed` while the facet stayed routed for 18 days, and neither existing safety net could see it. Three changes: - New `no-deprecated-facets` health-check invariant diffs the on-chain facet set against `_targetState.json` and warns on facets that are routed, name-resolvable in the deploy log, unprotected, and whose `.sol` source is gone. `no-unexpected-facets` only asks whether a facet is *known*; this asks whether it *should still be there*. Target-state drift (source still present) is excluded as a separate, much noisier failure class. - `reconcile-parked-tasks` resolves facet presence by NAME rather than by the stored address snapshot, and re-verifies terminal `executed`/`superseded` tasks instead of trusting them. A task whose facet is still routed is reopened to `queued` and alerted. - The reconcile sweep isolates each network, so a retired chain that left `networks.json` can no longer abort the run and leave every later network — worldchain included — silently unverified. Read-only with respect to chains; no Safe proposals are created. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Coordination note: PR #2157 (EXSC-723, ready for review) now also ships per-network fault isolation in |
Folds fix/exsc-780-reconcile-deprecated-network-selfheal into the EXSC-723+774 branch so the queue work ships as one reviewable change. Conflict resolution takes the #2201 reconcile as the base — IReconcileRun {reopened, failures}, name-primary presence via resolveFacetPresence, the safe-to-prune report, and the loupe-only degrade when the signing-store tunnel is down — and drops this branch's duplicate isolation and process.exitCode approach in favour of it. Their per-network failures are Slack-alerted, which is strictly more informative than a bare non-zero exit. Kept from EXSC-780, none of it duplicated by that base: - Tasks on a network outside the active set are routed out before the loupe is touched and reported with the command that resolves them, so they no longer fail per-network every week with no way to act on the alert. - Cancelling one is opt-in and single-network (--network X --cancel-deprecated --yes); a fleet-wide cancel is refused. config/networks.json is narrowed to three networks for pause rehearsals, so an unattended run must never read it as a fleet-wide deprecation. - The sweep as a whole is guarded: per-network throws are already contained, but a throw before reconcileAll returns would still have skipped both alert paths and the TTL backstop. - --ttlDays must be a positive integer; a bare Number() gave NaN, which makes ageDays < ttlDays false for every task and alerts on the whole open queue. - getSafeMongoCollection closes its client when the index creation fails after connecting, which matters now that an unreachable store no longer aborts. Docs follow the merged behaviour: the state machine carries both new terminal paths, and the exit-code claims are replaced with the Slack-alert model.

The reconcile alerts degrade to log-only when the Slack webhook is unset. A cron log nobody reads is not an alarm, so say when there was something to raise and no webhook to raise it on. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Reopened in error by me a few minutes ago — I was chasing what looked like a stale PR head (pushes to a closed PR don't advance it) and hadn't yet read the fold-into-#2157 note above. Re-closing to restore the intended state. Apologies for the noise. For the record, one commit here is not in #2157: Two findings from this branch that may be worth carrying into #2157's description as well:

Why did I implement it this way?
A facet removal that never executed could be recorded as done and then stay invisible indefinitely. On worldchain the parked
AcrossFacetV3task was markedexecutedon 2026-08-03 whileAcrossFacetV3at0x08F7800449ad6681bd607EF21d3cc9C9dDDaF1C8is still routed by the diamond today — 18 days later. Neither existing safety net could see it:no-unexpected-facetscompares on-chain facets againstdeployments/<net>.jsonand warns only on addresses absent from that log. Deprecated facets are never pruned from the deploy log, so a deprecated-but-logged facet reads as "known" and passes. That invariant answers "is this facet known?", not "should this facet still be here?".reconcile-parked-tasksonly reconciledqueued/proposedtasks.executedwas terminal and never re-verified, so a false-executedwas permanent by construction.The root cause is not what the ticket first assumed
The worldchain task's stored
facetAddressis0xB5dD83183fD7CCF859b227CA83663a034d5B2f92— lisk'sAcrossFacetV3v1.0.0, not a worldchain address at all. That address genuinely is not routed on worldchain, so the reconcile's address-based presence check correctly concluded "gone" while checking the wrong address entirely. The facet actually routed under the nameAcrossFacetV3on worldchain was never examined.So re-verifying the stored address — the fix as originally proposed — would not have caught this. Proven against live data:
Presence therefore resolves by facet name first, with the stored address kept only as a fallback (so a pruned deploy-log entry still can't false-resolve a live facet). This also aligns the reconcile with the drain, which already removes by name via
computeNamedFacetRemovals— otherwise the two disagree about what "done" means.What changed
1. New
no-deprecated-facetshealth-check invariant. Diffs the on-chain facet set against_targetState.jsonand warns on facets that are routed, name-resolvable in the deploy log, unprotected, and whose.solsource no longer exists (i.e. genuinely deprecated). ReusesdiffFacets— the same diffcleanUpProdDiamond --autocomputes, which was never wired to a scheduled alarm. Severitywarning, so it surfaces without failing bring-up on partially-deployed networks.Deliberate scope choices:
activeSelectorsis passed empty: this is detection only, so nothing needs holding back, and populating it requires compiled artifacts and throws when they are stale — unacceptable inside a health check. The real removal path still computes the true held-back set.2. Name-primary presence + terminal re-verification in
reconcile-parked-tasks.executed/supersededare re-verified against the loupe on every run; a task whose facet is still routed is reopened toqueued(so the next drain re-proposes it) and alerted to#dev-sc-multisig-proposals.supersededis included because it makes the identical "we believe it's gone" claim.cancelledis deliberately excluded — it records an operator's decision, not a claim about on-chain state.3. Per-network isolation in the reconcile sweep — this one is load-bearing, not incidental. The fleet sweep was aborting at
harmony, a retired network that kept its parked tasks but leftnetworks.json, so the loupe read threw and killed the run. Every network ordered after it was never reconciled — worldchain included. Without this fix both changes above would have been inert in the scheduled job for the very network that motivated the ticket. Skipped networks are now alerted with a remedy rather than silently dropped.4. Alert delivery is no longer silently optional. All three reconcile alerts degrade to log-only when
WEBHOOK_DEV_SC_MULTISIG_PROPOSALSis unset (pre-existing behaviour for the TTL alert, inherited by the new ones). The job now says so explicitly rather than degrading in silence — the same failure class this PR closes.Fleet-wide scope of the underlying problem
worldchain is one instance of a systemic backlog, not an isolated incident. A probe of the loupe ∖ target-state diff across all active production networks found ~50 networks with at least one deprecated-but-live facet (~100 findings), dominated by
GenericSwapFacetandCBridgeFacet/CBridgeFacetPacked. The new invariant will be loud on its first run; that volume is a real cleanup backlog, and draining it is tracked separately (see follow-ups).Verification: proven to fire on real data, not just in unit tests
Same-PR unit tests are not evidence a new check works, so each was falsified against the live queue and live chains (read-only; no Safe proposals created).
Invariant fires, and discriminates:
Reconcile fires on the real false-
executed, and discriminates within the same network — all three worldchain tasks had an executed proposal, only the one still routed reopened:Fleet sweep now completes instead of aborting, with no false-reopen storm — 123 tasks decided (previously the run died after ~47), exactly 1 reopen across the whole fleet, and the 3 unreconcilable retired networks reported rather than fatal:
Operational impact a reviewer should weigh
This changes the daily healthcheck's Slack behaviour.
healthCheckAllNetworks.ymlposts whenwarned_count != 0, and its own comment states that a green run "stays silent to keep the channel signal-only." Because the invariant iswarningseverity, the ~50 affected networks all land inwarned— so the daily job will post every day, listing them, until the backlog is drained (weeks of Safe proposals across ~50 chains).Two readings, both defensible:
Worth noting the channel likely already posts on many days:
facets-registeredwarns on any RPC failure, and the fleet probe for this PR hit 404/429/403/revert on arbitrum, bsc, moonbeam and gravity. So this may be incremental rather than a regime change — but I did not measure the current baseline, and that is the number that decides it.Coverage of the new invariant is 69/72 active networks. The 3 skips —
arbitrumsepolia,basesepolia,tronshasta— have no production target-stateLiFiDiamondblock, which is correct for testnets. This is deliberately the inverse of the failure that gotno-unexpected-erc20proxy-callersdeleted in #2156 (silently no-oped on 38 of ~62 networks while the sweep still reported green): here the skip set is small, is testnet-only, and is logged per network.Follow-ups (deliberately out of scope)
