Count railway track as infrastructure in every province it crosses

[Drefvelin]

Summary

Railway track now counts as infrastructure. Every land province a railway crosses becomes a source of 10 (infrastructure.track), once per province, on top of any station or other source there. It works in unowned land too, where it spreads only through unowned land, as the infrastructure core already defines.

• The track provinces come from VehicleFramework's new TrackRegistry.sampleTrack, so this needs VehicleFramework 2.8.0 (vehicleframework.version is bumped).
• VehicleFramework is only read on the server thread: at startup, at the day change, and every infrastructure.track-refresh-seconds (default 300, minimum 30). Recalculations, including the ones income previews run off the server thread, read a cached immutable set.
• When a refresh finds the set changed, trade is recalculated straight away. When it has not changed, nothing happens.
• If VehicleFramework is missing or too old, there is no track infrastructure and one warning is logged.

Testing

mvn verify: 2,576 tests pass. New tests cover mapping sample points to provinces, track as a source (alone, with a station, in sea, in unowned land), the refresh only recalculating on change, and a failed lookup giving an empty set.

📝 Summary

Summary by CodeRabbit

• New Features
  • Track infrastructure contributes to province infrastructure and can spread to eligible unowned land.
  • Track data refreshes at startup, periodically, and during the daily supply hub update. The contribution amount and refresh interval are configurable.
• Compatibility
  • Updated compatibility with VehicleFramework 2.8.0.

Walkthrough

The plugin now samples track points into province IDs and includes those provinces in infrastructure calculations. Track infrastructure and its refresh interval are configurable. Track province data refreshes at startup, on a repeating schedule, and during the daily supply-hub step.

Changes

Track infrastructure

Layer / File(s)	Summary
Track settings and dependency pom.xml, src/main/java/net/tfminecraft/simplefactions/Cache.java, src/main/java/net/tfminecraft/simplefactions/loaders/ConfigLoader.java, src/main/resources/config.yml, src/test/java/net/tfminecraft/simplefactions/loaders/ConfigLoaderInfrastructureTest.java	The VehicleFramework version changes from 2.7.0 to 2.8.0. Configuration adds track infrastructure, defaulting to 10, and a refresh interval, defaulting to 300 seconds and clamped to a minimum of 30.
Track sampling and refresh src/main/java/net/tfminecraft/simplefactions/SimpleFactions.java, src/main/java/net/tfminecraft/simplefactions/guild/hub/VehicleFrameworkTrackProvinces.java, src/main/java/net/tfminecraft/simplefactions/map/infra/TrackProvinceCache.java, src/main/java/net/tfminecraft/simplefactions/map/infra/TrackProvinceLookup.java, src/test/java/net/tfminecraft/simplefactions/map/infra/TrackProvinceCacheTest.java, src/test/java/net/tfminecraft/simplefactions/map/infra/TrackProvinceLookupTest.java	Track points are mapped to valid land provinces. The shared cache updates when the sampled set changes and handles sampling failures by using an empty set and warning once. The plugin refreshes track data at startup and on a repeating schedule, and cancels the scheduled task at shutdown.
Infrastructure calculation src/main/java/net/tfminecraft/simplefactions/managers/FactionManager.java, src/main/java/net/tfminecraft/simplefactions/managers/ProvinceManager.java, src/main/java/net/tfminecraft/simplefactions/map/infra/InfrastructureSources.java, src/test/java/net/tfminecraft/simplefactions/map/infra/InfrastructureSourcesTest.java	Infrastructure collection now accepts track province IDs and adds the configured track amount for those provinces. The daily supply-hub step refreshes track data and recalculates provinces only when the refresh reports no changes. Tests cover track source contributions, source combination, and spread to unowned but not realm-owned provinces.

Merge Risk: ⚪ Minimal · up to 0a54a

Track infrastructure is sampled at startup and refreshed on the configured schedule; an unavailable VehicleFramework integration is handled as optional. No actionable merge risk remains in the reviewed change.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 0a54a

The integration retains province validation and existing ownership-aware calculations. However, a failed recalculation can leave a refresh marked complete, preventing unchanged scheduled samples from retrying it. No player-triggerable boundary bypass was established.

Retained concerns

• Low · reliability · inferred: A changed track snapshot is stored before its recalculation succeeds. If recalculation throws, the snapshot remains current and unchanged scheduled samples do not retry application, potentially leaving infrastructure and trade state stale or partially updated. A later daily full recalculation can repair this, but the refresh flow has no pending-application state. This is an inferred failure-containment concern, not a demonstrated attacker-induced failure.

Security review details

Security Blast Radius

• inferred — The affected scope is land provinces reached by track samples in the configured world, followed by province infrastructure and guild trade calculations. The observed consequence is game-economic state, not newly granted operating-system or service authority.

Trust Boundaries and Controls

• observed — The plugin dependency boundary is mediated by a dedicated sampling adapter and province validation. Immutable snapshot publication limits downstream access to province IDs, and the shown startup and scheduled refresh paths keep external sampling under server lifecycle control.

Resilience and Maintainability Implications

• observed — Sampling exceptions are contained by an empty-set fallback, but recalculation exceptions are outside that catch. Immutable snapshots protect the sampled set itself; they do not make the mutable infrastructure, production, prosperity, and income updates atomic.

Hardening Proposals

• proposed — Track successful application separately from the sampled snapshot, retaining a pending-recalculation marker after callback failure so an unchanged scheduled sample can retry. Preserve the immutable reader handoff and single server-thread writer model.

- Around line 535-536: Update the VehicleFramework availability guard in the
method containing `provinceGrid` to emit a warning only once when the plugin is
unavailable, while preserving the empty-set return. Alternatively, route this
unavailable state through `TrackProvinceCache.refresh` so its warning mechanism
reports it without repeated warnings.
