Do not update active-snapshot gauges after read-back failure.
RefreshStats counts territories processed during the refresh pass. When store.load() fails, inspector.publish(...) is skipped, so the inspector keeps its previous snapshot. The code still publishes those pass counts to gauges whose comments define them as the current cache and verdict state.
Update these gauges only after inspector.publish(...) succeeds. Use separate refresh-result metrics if both states must remain observable.

Test verified-list propagation through qualification.
This test publishes an empty lists vector and uses a self-issued CMS seal. standing returns SelfIssued before it examines lists, while qualify copies unchecked directly. Therefore, the test still passes if publish drops the verified lists or qualification does not receive held.lists.
Publish a verified-list fixture through the refresher and assert that the resulting CMS verdict matches or consults that list. This test must cover both halves of the published snapshot.

The concurrency design is correct for the inspected request path. I found one issue in the publish condition:
The task should publish only if the cache read-back represents every territory from the verified LOTL. Otherwise, it must retain the previous inspector snapshot. The refresh result can carry a completion or persistence-failure status, or the task can validate cache coverage before

Closes #361.
CadesInspectorheld the trusted lists it was handed at boot and had no way to be given a newer set. The refresh task (#353) writes only to the database, so a completed pass reached a running node's verdicts not at all — only the next restart, for whatever unrelated reason it happened.#356's CHANGELOG states that limit honestly. What neither PR reckoned with is that it is not an edge case: #353's first pass runs 60 seconds after boot, so on a fresh deployment the set read at startup is always the empty one. Turn

Cloneshares it.mainkeeps one handle for the read path and gives another to the refresh task, which publishes into it after each completed pass.Three choices worth arguing with:
std::sync::RwLock, notarc-swap. No new dependency, so nothing to weigh against the untrusted-input question. The read path clones the innerArcand drops the guard before the ASN.1 and signature work — so no lock is held across a verdict, and a publish landing mid-verdict cannot change the set underneath one.Arc<RwLock<Arc<..>>>: the innerArcis the snapshot, the outer one is what makes a clone see the publish.Both halves in one struct.
listsanduncheckedare now fields ofTrustedListSetand can only be replaced together. That invariant was previously prose repeated in three doc comments — a node holding 26 of 27 lists that reported only the 26 would answer "this issuer is on no list" for a perfectly qualified provider in the twenty-seventh. It is now the type.Published only after a pass that completed, and re-read from the cache.
refresh_oncereturnsNonewhen it abandoned a pass, so a set that cannot describe its own width never reaches a verdict — the same rule0038took for the seal audit, which publishes a report only on reaching the end of the estate. And the task re-reads the cache rather than assembling a set fromstats, so what lands in the inspector is exactly what a restart would have loaded. If that read-back fails, the previous set stays: stale and wide beats fresh and vacuous.A poisoned lock recovers via
PoisonError::into_innerrather than panicking. The only writer ispublishand the only reader clones and leaves, so no half-written set is observable — and a panic in an unrelated task should not silently freeze every seal verdict on the node.The test
