feat(healthcheck): intent-aware facets-registered + periphery-registered — scheduled registrations report as expected-pending (EXSC-847)

[0xDEnYO]

Which Linear task belongs to this PR?

Fixes EXSC-847

Why did I implement it this way?

facets-registered is severity error, and its expected set comes from
script/deploy/_targetState.json — not from the deploy log. A rollout PR merges the
target-state entry before the diamond cut executes, so the affected networks go red with
no way to say "a scheduled proposal adds exactly this facet". periphery-registered has
the same shape. no-stale-registered-facets already solved the mirror-image problem for
removals by consulting the parked-task queue; this applies the same pattern to additions.

What this actually covers — narrower than "merge to execution". A queue row is written
only once the Safe transaction executing scheduleBatch is mined, so the multisig signing
window before that stays red. Measured across the 900 executed rows in the live queue,
create→execute is p50 ~3.3 h / p90 ~4.1 h against a uniform 3 h delay, so the covered slice
is the timelock delay plus execution lag. Three paths are not covered at all, and are named
in [CONV:HEALTHCHECK-INTENT] so nobody reads a red network as a broken invariant: the
signing window, any rollout proposed without --timelock, and Tron (which rolls out
through contracts-tron and has no EVM queue row).

Intent source: the timelock queue, not Safe proposals. Two reasons, pointing the same
way:

• The timelock queue lives on the un-gated cluster whose URI healthCheckAllNetworks.yml
  already passes. The Safe proposal collection needs the tunnel-gated credential the
  health-check workflows do not carry — sourcing intent there would make the downgrade
  permanently inert in CI, the one place it matters. This is also what bounds coverage to
  the delay window rather than the signing window; widening it means giving the workflow
  that second credential, which is a separate decision.
• A queued row means the Safe transaction already executed scheduleBatch, so the
  operation is live on the timelock. An unsigned Safe proposal may never be signed;
  treating it as intent would over-claim.

Coverage is keyed by address and by diamond, not by name — the same lesson the parked
queue learned in EXSC-750/EXSC-775. A downgrade requires a queued operation that
registers exactly the deploy-log address, via an inner call targeting that network's own
diamond. Remove cuts are ignored because they leave nothing routed, as is a
registerPeripheryContract to the zero address, which is a removal in periphery clothing.
A non-zero _init address (present in 101 of 615 real diamondCut payloads) is
delegatecalled during the cut but never becomes a routed facet, so it is never counted.

Queued rows are honoured only while plausibly still waiting. When a Safe transaction
never actually scheduled its batch, or an operation was cancelled directly on the timelock,
execute-pending-timelock-tx.ts reports it and continues without updating the status —
so the row stays queued forever. That state (deployed, recorded in the deploy log, cut
never landed) is exactly what these gates exist to catch, and honouring such a row
indefinitely would invert them. Rows past their delay plus a 3-day grace
(STALE_QUEUE_GRACE_MS = 3 * DAY_MS) are dropped and report as hard errors; three days
clears the slowest real rollout on record (~70.7 h create→execute) while still being finite.

An unreachable queue does not suppress anything. This is a deliberate deviation from
no-stale-registered-facets, which returns early and reports skipped coverage. What
separates them is what each check is for, not its severity — since #2280 all three are
error-severity. no-stale-registered-facets exists only to police queue coverage, so
without the queue every finding it could make is noise. These two stand on an independent
on-chain signal and are the fleet's primary registration gates: a MongoDB blip turning
genuinely missing registrations green is far worse than a false alert during a rollout, so
every error survives and a warning names the degraded coverage — which also lands the
network in the sweep's warned list instead of looking clean.

The generator boundary is untouched. Intent-awareness is safe in alerting (a bad
queue read costs a false alert or reduced coverage, self-correcting next run) and unsafe in
generation (a bad read or a later-cancelled task would leave a wrong deploy log in git
with no owner for the compensating write). Deploy logs stay a pure function of the loupe;
this PR adds no path from intent into saveDiamondFacets.

Verification on real data

Same-PR tests are not evidence a new check can fire, so both invariants were falsified
against the live timelock queue and real repo state. All figures below were re-measured
against the live queue on 2026-08-31, after the merge with main:

• 902 real queue rows decoded (900 executed, 2 cancelled, 0 queued, 0 failed).
  All 9 real inner-call selector shapes are accounted for: diamondCut (615) and
  registerPeripheryContract (190) yield registrations; the other seven —
  batchSetContractSelectorWhitelist (264), grantRole (80), revokeRole (71),
  setChainIdToDomainId (54), setFraxChainIdToEid (24), transferOwnership (3) and
  confirmOwnershipTransfer (3) — correctly yield none, as do the 256 pure-Remove cuts.
  541 rows yield at least one registration, so the decoder fires on real production
  payloads. setFraxChainIdToEid is new since the first measurement (FraxFacet v1.0.0
  rollout, chore(deployments): roll out FraxFacet v1.0.0 to production (EXSC-387) #2254) and is handled correctly with no code change — a config setter registers
  nothing.
• Address/diamond keying holds fleet-wide: 514/514 non-Tron registrations have their
  inner-call target equal to that network's LiFiDiamond in deployments/<net>.json; zero
  mismatches. The 17 Tron registrations are excluded by branch before any address match.
• End-to-end on the real invariants, driven with real deploy logs, real
  _targetState.json and real config/global.json:
  • tempo / GlacisFacet — 1 error without coverage → 0 errors, 0 warnings with real
    queue coverage → error preserved + 1 warning when the queue is unreachable.
  • somnia / GasZipPeriphery — same three outcomes through
    periphery-registered's own contractsToCheck filter.
• Blast radius today is nil: with 0 rows currently queued,
  listPendingRegistrationsByNetwork() returns 0 networks, so the error set is
  byte-identical to main. The diff adds no new logError call site — every one in it is a
  relocated pre-existing one. A fully green fleet opens no Mongo connection at all, since
  both call sites are gated on something actually being missing.
• The staleness bound was negative-controlled again after it was re-expressed as
  3 * DAY_MS: shrinking it to 1 * DAY_MS fails exactly the test asserting the ~70.7 h
  rollout is still honoured, and restoring it passes. Across the refreshed 900-row corpus,
  zero executed rows exceed delay + grace.
• 195 tests pass across pending-registrations.test.ts and
  healthCheckInvariants.test.ts, and the full bun test script/ suite is green at
  1222 across 53 files.

Merged with main

The branch was 65 commits behind and conflicting. Merged; all three conflicts were additive
import/interface hunks against #2280 (fix(healthcheck): a stalled parked claim is not removal coverage), which landed in the same two functions. Two changes came out of that
merge rather than out of review of this feature:

• The [CONV:HEALTHCHECK-INTENT] rule and the matching code comment keyed the
  unreachable-queue rule on severity; fix(healthcheck): a stalled parked claim is not removal coverage (EXSC-867) #2280 promoted no-stale-registered-facets
warning → error, so that framing was false. Both now key on what the check is for,
  which is the load-bearing reason either way.
• STALE_QUEUE_GRACE_MS was a bare 72 * 60 * 60 * 1000. fix(healthcheck): a stalled parked claim is not removal coverage (EXSC-867) #2280 established DAY_MS in
  shared/constants.ts plus an exported bound its tests import; this now follows that —
  export const STALE_QUEUE_GRACE_MS = 3 * DAY_MS, and the fixtures derive from it instead
  of hardcoding hours.

Coordination with #2244 (EXSC-816), for whoever lands second

#2244 adds a blocked queue status for
an operation a pre-execute guard refuses. Such a row is a live, scheduled timelock
operation awaiting requeue, but listPendingRegistrationsByNetwork() filters
{ status: 'queued' }, so once #2244 lands a blocked rollout stops being covered and its
networks report hard errors until it is requeued. The direction is safe (over-alert, never
hide) and matches this module's stated posture, but it is a real behavioural coupling:
whoever merges second should either add blocked to the intent filter or record why it is
excluded. Not done here — blocked is not in TimelockQueueStatus on main, so it could
not be falsified against real data, which is the bar for this check.

The JSDoc note about a failed row that is still executable describes exactly the defect
#2244 fixes; it should be retired in whichever PR lands second.

Registration identity: name- and target-bound records

CodeRabbit's Major finding on the first draft was correct and is now fixed. Two defects, one
root cause — the model kept only an address:

• False green (the dangerous one). registerPeripheryContract binds an address to one
  registry name. Keeping only the address meant a queued registerPeripheryContract('Other', EXECUTOR_ADDR) downgraded a missing Executor, even though getPeripheryContract('Executor')
  stays unset. On an error-severity gate that is coverage granted for a registration that is
  never coming.
• Lost coverage. Map<address, record> let a second inner call for the same address
  overwrite the first, so a later non-diamond target could erase real coverage. Same shape
  CodeRabbit flagged as Major on fix(healthcheck): a stalled parked claim is not removal coverage (EXSC-867) #2280 (fetchOpenParkedAddressesByNetwork).

IPendingRegistration now carries the registry name (absent for facet cuts), and every record
per address is kept rather than the last one winning. Matching tightened accordingly: a facet
is covered only by a diamondCut record — a registry entry routes no selectors — and a
periphery contract only by a record carrying its own name.

Falsified on real data, not just the new tests:

• The decoder pulls 8 distinct registry names out of the 190 real
  registerPeripheryContract calls in the live queue (OutputValidator 73, FeeForwarder 67,
  ReceiverOIF 33, Executor 5, ReceiverAcrossV4 5, GasZipPeriphery 3,
  ReceiverStargateV2 3, ERC20Proxy 1). 168 of 190 agree exactly with the name→address
  mapping in deployments/<net>.json; the other 22 are historical rows whose address has since
  been superseded. A name-blind matcher had nothing to compare here.
• Both new requirements are negative-controlled: relaxing the periphery name check to
  some(() => true) fails exactly the wrong-name test, and relaxing the facet check fails
  exactly the periphery-record test. Restoring each passes.
• Same-address multi-target collisions in the live corpus: 0 of 902 rows — the overwrite
  was latent, the name defect was not.

Adjacent finding, not fixed here

Re-confirmed against origin/main today: MayanFacet is listed in
deployments/optimism.staging.json but is not routed by the loupe, and optimism has no
staging target-state entry. That is a prune #2252 missed — bookkeeping only, no invariant
reds on it. Left out to keep this diff to one problem.

Third false green: the registry match was name-blind (c78b56728)

Raised by CodeRabbit on this PR, confirmed, and fixed here. addresses is built
index-aligned with contractsToCheck, but the comparison was
addresses.includes(getAddress(peripheryAddress)) — a hit anywhere in the resolved set,
not the entry at the requesting name's index. Two contracts bound to each other's names
therefore both reported success, and because that path reports success it never reached
reportUnregistered, so this PR's queued-name check could not run for them at all. It is
the on-chain analogue of the false green fixed in c0f805ec2: same root cause, an address
treated as if it carried its own name.

Not introduced here — origin/main carries the identical line at :1853, from 7bbe2b6a5
(#2078, 2026-07-21). Fixed in this PR rather than deferred because it defeats this PR's own
feature: the intent-aware downgrade is unreachable for exactly the contracts the defect
mislabels as fine.

The regression test was wrong before it was right, which is the point. The first version
of errors on both when two periphery contracts are registered under each others names
passed against the unfixed code — its stub returned raw-case literals, so
includes(getAddress(…)) missed on checksum casing rather than on the name binding, and the
test proved nothing. Returning properly checksummed addresses, as a real readContract
does, makes it fail on main's logic and pass on the fix. Negative-controlled in both
directions.

Blast radius, measured offline. The change is strictly stricter, so it can only turn
passes into failures. For a network to newly red, the deploy-log address of one periphery
name must equal the registry's value at another name's index — across all 95 per-network
deploy logs, zero networks have two core-periphery names sharing an address, so any new
red is a genuine on-chain mis-binding rather than a bookkeeping artifact. The live registries
themselves were not swept: those RPCs are tunnel-gated and unreachable from this session, so
this is a deploy-log-side bound, not a fleet dry-run.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to c78b5

The PR adds queued-operation awareness to registration health checks, but the current head can suppress stale-facet errors during queue outages and can prefer a stalled task over a live task, producing incorrect monitoring results. These bounded correctness issues should be fixed before merge.

/gate-review residual — not fixed, needs a human call

Auto-fixed findings are in 9cb41e4 and the updated PR body. These are the ones left open.

1. Coverage stops short of the signing window — product decision, not a bug.
A queue row appears only once the Safe tx executing scheduleBatch is mined, so the
multisig signing window before it stays red. Measured on 874 live rows: create→execute p50
~3.3 h, p90 ~4.1 h, against a uniform 3 h delay. Extending coverage to the signing window
means giving the health-check workflow the tunnel-gated Safe-collection credential — a
security/infra decision I am not taking unilaterally. Documented as an explicit non-goal in
[CONV:HEALTHCHECK-INTENT] rather than silently implied.

2. deployUpgradesToSAFE.sh is never covered.
script/deploy/deployUpgradesToSAFE.sh:67 (reachable from scriptMaster.sh:561) proposes
the diamondCut directly, without --timelock, so it writes no queue row and its networks
stay red through their whole pending window. diamondUpdateFacet.sh,
diamondUpdatePeriphery.sh and proposePeripheryWithWhitelist.ts all pass --timelock and
are covered. Named as a carve-out in the rule doc. Whether that script should route through
the timelock is a governance question, not something to change inside this PR.

3. Coverage is tool-path dependent.
A Safe tx executed via the Safe web UI or another signer's client writes no queue row until
someone next runs confirm-safe-tx.ts / confirm-safe-tx-prefetch.ts — the only importers
of reconcile.ts, and there is no reconcile workflow for it. Fails toward over-alerting, so
it is safe, but it means the downgrade is not guaranteed for out-of-band executions.

4. The health check now issues createIndex on a read-only job.
getTimelockQueueCollection() calls ensureTimelockQueueIndexes() (two createIndex
calls) on every health-check process, though the workflow describes itself as read-only.
Idempotent and Unauthorized-tolerant, and identical to what the parked-task queue already
does — left alone rather than forking a read-only accessor for one caller.

5. Merge-order coordination with #2213.
#2213 splices a new invariant
(immutable-bindings-match-config) into the array at exactly the seam this PR restructures
— between facets-registered and periphery-registered. It is already CONFLICTING against
main. Whichever lands second needs a real conflict resolution, not a mechanical rebase.

6. Mongo-outage cost, accepted.
On a hard outage the shared promise is cleared per failure, so ~74 networks at concurrency 8
gives roughly 10 serialized waves at the driver's 30 s server-selection timeout — about
5 minutes added to a ~45 minute job. Bounded, and the same URI already feeds the earlier
fetch-rpcs step, so a broken URI degrades the run before invariants execute anyway.

RESOLVED in c0f805ec2 — remedy 1 (lossless value). The fix is intentional, not a
rebase residue: this note went up at 12:38 UTC and the fix landed at 12:45 UTC the same
day, so it was already stale when QA read it. IPendingRegistration is now carried as
Map<address, IPendingRegistration[]> end to end — registrationsFromQueueDoc pushes
into a per-address array instead of set-ing, groupRegistrationsByNetwork concatenates
on merge, and resolvePendingRegistrations returns the target-filtered records. Remedy 1
was chosen over remedy 2 because CodeRabbit's Major name-binding finding shared this
finding's root cause (the model kept only an address), and carrying the registry name
required multiple records per address anyway — one change closed both. Nothing below is
outstanding; the original text is kept for the audit trail.

/gate-review residual — 1 escalated finding

script/deploy/safe/pending-registrations.ts (registrationsFromQueueDoc, groupRegistrationsByNetwork) — same-address, multi-target collision silently drops coverage.

Both functions key registrations by address in a Map, so two inner calls on the same network registering the same address against different targets collapse to whichever came last. CodeRabbit flagged the identical shape as 🟠 Major on #2280 (fetchOpenParkedAddressesByNetwork overwriting one open task with another for the same address); it was fixed there in 8b162cd.

Escalated rather than auto-fixed because two defensible remedies exist (the gate's floor escalates when more than one valid fix is available):

1. Lossless value — IPendingRegistration.target: string → targets: string[], with resolvePendingRegistrations filtering on targets.includes(diamond). Correct, but changes a type consumed by IHealthCheckContext and both test files.
2. Prefer the diamond-targeted entry on collision, keeping the current shape.

Severity context, measured rather than assumed: across all 902 live queue rows there are zero same-address multi-target collisions, so this is latent. The failure direction is also safe — a clobbered target can only make the diamond match fail and yield a false error, never grant coverage that was not scheduled.

Checked and clear

• IPendingRegistration does not hand-copy ITimelockQueueDoc fields — both decode helpers take Pick<ITimelockQueueDoc, …>, which is what melianessa asked for on fix(healthcheck): a stalled parked claim is not removal coverage (EXSC-867) #2280 (IOpenParkedCoverage).
• The bare 72 * 60 * 60 * 1000 literal is gone — now 3 * DAY_MS, following the DAY_MS convention fix(healthcheck): a stalled parked claim is not removal coverage (EXSC-867) #2280 established after melianessa flagged the duplicated 86_400_000.
• Falsification: decoder re-run over the live queue (902 rows, 9 selector shapes, 541 yielding registrations, 514/514 diamond-keyed with zero mismatches); staleness bound negative-controlled after being re-expressed as 3 * DAY_MS.
• No new logError site; with 0 rows currently queued the error set is byte-identical to main.
• Coverage claim vs probe reconciled: Tron / testnet / staging are excluded by branch before any lookup, and the periphery Tron branch therefore always falls through to the error.

Note: the gate's parallel review agents were not used this run (agent dispatch was disabled for the session); its seven review dimensions were executed inline instead.

Analysis of Post-QA Commits

537c81b1a843 — test(healthcheck): pin the periphery target filter

Adds two new test cases to the periphery-registered scheduled-registration coverage describe block:

"still errors when the queued operation targets another contract"
covering('Executor', OTHER_TARGET) passes a pending registration aimed at a different diamond (OTHER_TARGET ≠ DIAMOND). The invariant must still error since resolvePendingRegistrations filters by target === diamond. ✅ Correct.

"errors on both when two periphery contracts are registered under each others names"
Executor registry returns getAddress(FEE_FORWARDER) and FeeForwarder registry returns getAddress(EXECUTOR). Both should error. The mock uses getAddress() (checksummed), matching what a real readContract returns — raw-case literals would cause a casing-mismatch failure before the name-binding logic, producing a false pass. PR body documents this explicitly; this is the correct way to test. ✅ Well-constructed.

c78b56728add — fix(healthcheck): compare the periphery registry entry for its own name

The fix:

Correctness analysis:

• addresses is built as contractsToCheck.map((c) => getPeripheryContract([c])) — each entry at index i is the on-chain registry value for contractsToCheck[i]'s name.
• Before the fix: addresses.includes() checked if the deploy-log address appeared anywhere in the registry, so FeeForwarder's address could satisfy Executor's check (false green).
• After the fix: addresses[index] is the registry value for this name's index. A different name's address at a different index cannot satisfy this check. ✅
• ?. optional chaining: if addresses[index] is undefined (structural mismatch), the expression becomes undefined !== getAddress(...) → true → error. Conservative, correct. ✅
• Both sides lowercased (addresses[index]?.toLowerCase() and getAddress(peripheryAddress).toLowerCase()) → case-insensitive comparison. ✅

Blast radius (developer-computed, logic-verified): The new check is strictly stricter. A correctly-registered network has addresses[i] and deploy-log address in agreement for every i. No false positives can arise unless two periphery contracts share an address — which the developer verified is zero-occurrence across all 95 per-network deploy logs. ✅

Additional Observations

AuditNotRequired label: Appropriate — health-check tooling only, no deployed contract changes.

Developer transparency: The developer initially stated the name-blind fix was "deliberately not fixed here" (comment at 01:39 UTC), then fixed it anyway 62 minutes later (c78b56728add at 02:41 UTC). The PR body explains the reasoning: the fix is required because the intent-aware downgrade is unreachable for exactly the contracts the pre-existing bug mislabels as fine. The change of approach is welcome, the fix is correct, and the rationale is sound.

QA: Needs Work — One item requires developer decision before merge: the same-address multi-target collision fix (array-accumulation in registrationsFromQueueDoc/groupRegistrationsByNetwork) appears already applied in the current branch, but the Round 2 escalation note remains unresolved. Required action: author confirms whether the fix is intentionally included (or applies it if not), then resolves the Round 2 escalation note in the PR. All 5 ACs otherwise verified. See QA comment for full details.

Re: QA blocker — collision fix is intentional, note was stale

Confirming option (a): the lossless array-accumulation fix is intentionally in this
branch. QA's reading of the code is correct; the Round 2 escalation note was simply never
updated after the fix landed.

Timeline — the note went up at 12:38:01Z, the fix commit c0f805ec2 is authored
12:45:17Z, seven minutes later. So the note described the tree as it stood when it was
written, and was already stale by the time it was read. Not a rebase residue: c0f805ec2
is a normal commit on this branch and its diff is exactly the shape change —
Map<address, IPendingRegistration> → Map<address, IPendingRegistration[]> in
registrationsFromQueueDoc (push-into-array instead of set), array concatenation on
merge in groupRegistrationsByNetwork, and target-filtered records out of
resolvePendingRegistrations.

Why remedy 1 rather than remedy 2. The escalation offered a lossless value or a
collision-preference rule. CodeRabbit's Major name-binding finding turned out to share this
finding's root cause — the model kept only an address — and binding the registry name
required more than one record per address regardless. Remedy 1 therefore fell out of that
fix rather than being a second change, which is also why it landed without the note being
revisited. Remedy 2 would have left the periphery name defect unaddressed.

The escalation comment is now marked resolved in place, with the original text kept below
the banner for the audit trail.

Coverage gap closed: 537c81b1a

QA's recommended follow-up is in rather than deferred — it is four lines and it pins a
filter nothing else pinned. periphery-registered had no case asserting that a queued
registration aimed at a different contract on the same network fails to downgrade, so
the target === diamond filter was load-bearing on that path with no test behind it
(facets-registered had its mirror). covering() now takes a target and
still errors when the queued operation targets another contract exercises it.

Negative-controlled, not just added: relaxing the filter in resolvePendingRegistrations
to records.filter(() => true) fails exactly two tests — the new periphery case and its
existing facet mirror — and restoring it passes. 194 tests green across
healthCheckInvariants.test.ts and pending-registrations.test.ts (was 193).

No production code changed in this push; the diff is the test file only, so the fleet
behaviour verified against the live queue is untouched.

Compare the registry result for the same periphery name.

Line 2027 checks whether the expected address appears anywhere in addresses. A swapped registry binding passes: getPeripheryContract('Executor') can return another address while another requested name returns the Executor address. The invariant then reports no error, and reportUnregistered cannot apply its exact queued-name check.

Compare the result at the matching request index. Add a regression test with two names that return each other’s addresses.

Re: CodeRabbit Major on healthCheckInvariants.ts:2027 — valid, pre-existing, deliberately not fixed here

The finding is correct. addresses is built index-aligned with contractsToCheck
(contractsToCheck.map((c) => getPeripheryContract([c]))), but the comparison is
!addresses.includes(getAddress(peripheryAddress)) — an any-match across the whole array
rather than the entry at the requesting name's index. Two names whose registry results are
swapped therefore both report success, and because that path reports success it never
reaches reportUnregistered, so this PR's queued-name check never gets a chance to run.
It is the on-chain analogue of the false green fixed in c0f805ec2.

It is not introduced by this PR. origin/main carries the identical line at
healthCheckInvariants.ts:1853; git log -S dates it to 7bbe2b6a5 (#2078, 2026-07-21),
six weeks before this branch. This PR touches the surrounding function but not that
comparison.

Why it is not riding along. Tightening includes → index-match strengthens an
error-severity gate, so it can newly red networks fleet-wide — precisely the case that
needs its own dry-run evidence across all 40+ networks rather than a same-PR test. Landing
it here would mean this PR ships an unmeasured change in fleet alerting alongside a feature
whose own blast radius was measured to be nil (0 rows currently queued, error set
byte-identical to main). Those two claims should not share a diff.

Filing separately with the fleet sweep as its acceptance bar. Adding it to the
"Adjacent finding, not fixed here" section of the PR body rather than leaving it only in a
bot thread.

@coderabbitai this is a valid pre-existing defect being tracked separately; no change in
this PR.

@0xDEnYO Confirmed.

The merge-base version contains the same addresses.includes(getAddress(peripheryAddress)) check. This PR changes only the branch that runs after the check fails. A swapped-name false success still bypasses reportUnregistered.

The defect is valid, but this PR does not introduce or worsen it. A separate issue with fleet dry-run acceptance criteria is the correct scope.

Timestamp: 2026-09-01T01:40:41.286Z
Learning: In `lifinance/contracts`, the `periphery-registered` invariant in `script/deploy/healthCheckInvariants.ts` historically compares each expected periphery address against all registry results with `addresses.includes(getAddress(peripheryAddress))`. This permits a false success when two periphery names have swapped registry addresses. The check is pre-existing and must be fixed in a separate change that uses the index-aligned registry result for each periphery name, with a fleet-wide dry run because it strengthens an error-severity health-check gate.

Learning: In the `lifinance/contracts` deployment health checks, pending periphery registrations must match the target diamond, periphery name, and address before an error is reported as expected-pending. Pending facet registrations must match the target diamond and address and must not carry a `peripheryName`. In `script/deploy/safe/pending-registrations.ts`, retain every target-bound registration for a given address because multiple queued registrations can share that address.

Keep stale-facet findings as errors when the queue is unreachable.

This branch logs a warning and returns. It suppresses the stalled and unparked error reports below, so a MongoDB outage can make routed deprecated facets non-error. Keep the warning, but continue with an empty coverage map so the affected facets remain error findings.

Proposed fix

         ctx.logWarn(

Keep a live parked task when one exists.

The replacement condition checks whether existing is stalled, but it does not check whether the incoming task is livelier. When one address has both a live task and a stalled task, the stalled task remains selected. no-stale-registered-facets then reports a false stalled-claim error.

Replace the stored task only when the existing task is stalled and the incoming task is not stalled.

Re: the two new Major findings — both declined, with reasons

Both are in no-stale-registered-facets, which this PR does not touch: each line is present
verbatim on origin/main (:1377 and :2656) and neither appears as an added line in this
PR's diff. Both were introduced by #2280. Verified rather than taken at face value, and
neither should be applied.

:1387 — collapseOpenParkedTasks preferring the live task would re-open the gap #2280 closed

This one is worth being explicit about, because the proposed diff is actively harmful.

The finding reads the map as "pick the best available coverage", so keeping a stalled task
over a live one looks like a false stalled-claim error. The function's contract is the
opposite — it selects the claim that governs coverage, failing closed. Its docstring
says so directly:

Collapsing them therefore has to fail closed — a stalled claim, once seen, is never
replaced by a livelier sibling, which would otherwise mask it and re-open exactly the gap
this coverage check exists to close.

Two open tasks can share one address because a legacy name-keyed row does not collide with
today's address-keyed computeTaskKey (mantle still carries such a row). If a live sibling
were allowed to win, the stalled claim would be masked and the facet would report as covered
— the EXSC-750/EXSC-775 co-registered-version gap, reintroduced.

The proposed condition would also fail two existing tests that assert this deliberately:
keeps the stalled claim when a livelier task for the same address follows it and
keeps the stalled claim when it arrives second ("order-independence is the whole point:
the queue's sort must not decide coverage"). A green suite after applying it would mean the
tests had been changed to match the regression.

:2849 — the unreachable-queue asymmetry is the documented decision, not an oversight

Making no-stale-registered-facets keep its errors when the queue is unreachable would
invert a decision this PR states and justifies in [CONV:HEALTHCHECK-INTENT]:

no-stale-registered-facets exists only to police queue coverage, so without the queue
every finding it could make is noise. These two stand on an independent on-chain signal
and are the fleet's primary registration gates.

facets-registered and periphery-registered each have a loupe/registry reading that is
true or false regardless of MongoDB, so an outage there costs coverage but never correctness
— they keep every error and warn. no-stale-registered-facets has no such second source: a
deprecated-but-routed facet is only a finding relative to whether a removal is parked. With
the queue down, every facet it could name is unverifiable, so reporting them as errors would
be a fleet-wide alert storm made of guesses. The asymmetry is the point, and the severity
promotion in #2280 did not change what each check is for.

Both are worth revisiting on their own merits in a PR that owns no-stale-registered-facets
— neither belongs here.
