📝 WalkthroughWalkthroughThe node status API now reads verified geolocation data from the contract, refreshes an atomically shared snapshot, indexes node identities and declared IPs, and composes location fields at HTTP response time.

Reject a zero refresh interval.
humantime::parse_duration accepts 0s. NodeDataRefreshWorker::run passes this value to tokio::time::interval, which panics for a zero period. The refresh worker then cannot publish geolocation data.
Add a parser or constructor check that requires geolocation_refresh_interval to be greater than zero.

Key location-dependent caches by GeoSnapshot.height.
get_dvpn_gateway_list, get_gateway_ips, and get_nym_nodes_list load geolocation only when their separate fixed-key caches miss. GeolocationRefresher::refresh later publishes a new snapshot, but it does not invalidate these caches. Responses can therefore serve stale gateway locations, country lists, ExtendedNymNode.geoip, and gateway IPs until the cache TTL expires. The default TTL is 30 seconds and is configurable.
Key all three caches by the current snapshot height, or compose the location-dependent fields at read time.

Node status API: geolocation from the contract
Replaces the node status API's own geolocation (a metered ipinfo lookup per node, memoised in a 24h in-memory cache) with a verified read of the geolocation contract. The service stops being an originator of unverifiable claims about
where the network is and becomes a consumer of ones anyone can check.
What changed
GeolocationClient::verified_geolocationover aProvenTrustAnchor, resolves each subject withDefaultResolutionPolicy, and publishes one atomically swapped snapshot.tip - 2. Same grid every attested contract shares, so a later directory read and a later move to nym-api-servedattested snapshots both join at a height this service already reads at. The height is selected once per tick and passed to the reader, so a second reader joins without a second selection.
locationleaves the persistedexplorer_pretty_bondrow and is composed per response instead.--ipinfo-api-token/IPINFO_API_TOKENandgeodata_ttlare removed. A deployment passing the flag on the command line fails to start until it is dropped.Response shapes
Checked against the live mainnet instance.
/dvpn/v1/directory/gateways(location) and/explorer/v3/nym-nodes(geoip) are byte-identical to what is served today./v2/gateways,/v2/gateways/{identity_key}and/v2/gateways/skinnykeepexplorer_pretty_bond.location- the nym-wallet (NodeOperatorInsights.tsx) and explorer-v2 both read it - with three deliberate departures, none of whicheither consumer touches:
asn.type"hosting")asn.kind, the derivedresidential/otheralready served on the dVPN surfaceip_addressserde_json::Value)locationis still always an object for a bonded gateway, nevernull, matching what a failed lookup produced before.Deployment
interval + lagblocks of state - 102 at the current defaults. A proven read at a pruned height cannot be served, and it fails loudly rather than falling back to an unproven height. A nyx signerRPC has previously been observed retaining about 100 blocks, which sits right at that edge.
--ipinfo-api-tokenfrom any command line that passes it. Deployments settingIPINFO_API_TOKENas an environment variable need no action; the variable is simply no longer read.Both contract addresses need no configuration: geolocation and directory ship in the network defaults for mainnet, sandbox and canary.
Coverage gate, before trusting the dVPN directory
Every refresh logs
geolocation refreshed at height H: N of M subjects resolved to a location. Mainnet currently serves 614 dVPN gateways with zero empty country codes, soNhas to approach that number. A node with no entryresolves to an empty country code and is dropped by the existing filter, exactly as a failed ipinfo lookup was - so a large gap silently shrinks the dVPN directory. Treat it as a blocker, not a curiosity. Per-node misses are logged at warn.
Freshness
Geolocation now moves on its own 30 minute clock, independent of
monitor_refresh_interval(300s). Tunable viaNODE_STATUS_API_GEOLOCATION_REFRESH_INTERVAL, hidden from--help. A failed refresh waits for the next tick; the held snapshot keeps being served meanwhile.Rollback
Redeploy of the previous version, but not instantaneous. The old binary declares
ExplorerPrettyBond.locationas non-optional with no serde default, so rows written by this version fail to deserialize under it and every gateway dropsout of the dVPN directory until one monitor cycle (up to 300s) rewrites them. It then self-heals with no intervention.
