Name the trade networks and add a viewer

[Drefvelin]

What changed

The trade networks from #120 get names, a screen, and a place in the map export.

Names

• The global network is The {map-name} Network, from the configured map name.
• Any other network is The {guild} Network, for the guild with the most trade at its stops. A guild name that already starts with "The" is not prefixed again.
• When no guild has trade at a network's stops, it is named for the faction that owns the most of them.
• Networks that would share a name get II, III after the largest.

Viewer

/guild networks, or the new Trade networks button on the Supply Hubs screen, lists the networks, largest first:

The Vardera Network
The global network.
Nodes: 21
Hubs: 19/42
Members:
- The Chisels (44%)
- Yevakeepers (39%)
- The Bog (10%)

• Nodes is the number of ports, airports and train stations.
• Hubs is every guild's active hubs in the network over the hub slots of its stops.
• Members are guilds ranked by their trade at the stops, including guilds with no hub. Five are shown, then Other.
• Clicking a network lists its stops with owner, kind, hubs and slots, and whether your guild has a hub there.

The screen reads the stored graph and trade when it opens. It does not recalculate anything.

Map export

map_markers.json gains trade_networks (name, global, nodes) and trade_edges (the two stops, mode, province path). hub_links is unchanged.

Testing

mvn verify passes locally: 2792 tests. The naming, hub counts and member shares are in a pure class with tests for each rule above, and the export test covers the two new arrays.

📝 Summary

Summary by CodeRabbit

• New Features
  • Added a guild trade networks view showing networks, their stops, hubs and trade shares, with navigation between network lists and stop details. Guild members can open it from the supply hub or use /guild networks.
  • Map exports now include trade network and connection data.
• Bug Fixes
  • If a selected network is no longer available, the viewer displays a message and returns to the network list.

Walkthrough

The change adds trade network summaries, guild command and inventory views for those networks, and trade network and edge data to map exports. Tests cover summary calculations and exported map data.

Changes

Trade Networks

Layer / File(s)	Summary
Build trade network summaries src/main/java/net/tfminecraft/simplefactions/guild/network/*, src/test/java/net/tfminecraft/simplefactions/guild/network/NetworkSummaryTest.java	CurrentNetworks supplies snapshot data to NetworkSummary. The summaries include network names, trade shares, hub counts, and ordering. Tests cover these calculations.
Open and navigate network views src/main/java/net/tfminecraft/simplefactions/enums/SFGUI.java, src/main/java/net/tfminecraft/simplefactions/guild/hub/SupplyHubCommands.java, src/main/java/net/tfminecraft/simplefactions/managers/CommandManager.java, src/main/java/net/tfminecraft/simplefactions/managers/InventoryManager.java, src/main/java/net/tfminecraft/simplefactions/managers/inventory/{InventoryUpdater,NetworkViewer,SupplyHubView}.java, src/main/java/net/tfminecraft/simplefactions/utils/TabCompletion.java	/guild networks and the supply hub open a paginated network list. Players can open a network’s stop view, navigate pages, and return to the list or guild view.
Export trade networks and edges src/main/java/net/tfminecraft/simplefactions/map/export/Markers.java, src/test/java/net/tfminecraft/simplefactions/map/export/MarkersInstallationKindTest.java	Map exports add trade_networks and trade_edges arrays. Tests check their contents and placement in the exported JSON.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 7eaba

Any guild member can now browse world-wide trade summaries without the foreign-guild visibility checks used by detailed screens. The views are read-only and show aggregates rather than full economic records, but the intended visibility of protected guilds’ contributions and externally exported routes remains unresolved.

Retained concerns

• Medium · security · inferred: The new global viewer exposes named guilds’ rounded network trade contributions without consulting the visibility policy that restricts detailed foreign-guild screens. Whether these aggregates are deliberately public is not established. This creates an inferred confidentiality-policy mismatch, bounded by substantial preexisting map exports of related economic data.

Security review details

Security Blast Radius

• inferred — The new read path spans the game world’s networks and contributing guilds, rather than only the requesting guild’s assets. The inspected path grants no administrative or shared-state write authority. The external audience for the map-export file is unknown.

Security Findings and Attack Paths

• inferred — A member of one guild can invoke the new command and inspect another guild’s network contributions without that target’s exact-information permission. This may reveal economic participation intended to be protected, but classification is unresolved and base map exports already exposed substantial related data. No verified new secret-data disclosure is established.

Trust Boundaries and Controls

• observed — The existing detailed supply-hub screen uses canViewExact, allowing faction members, permission bypasses, or targets without an eligible spymaster; otherwise it renders reported information with hub details unknown. The new summary viewer does not invoke that policy. Its GUI button is initially placed inside the guarded detailed screen, but the new command independently reaches the global viewer.

Resilience and Maintainability Implications

• observed — Production export still targets a fixed server-side file and publishes through direct FileWriter output. Failure or interruption can leave partial output, with exceptions logged rather than recovered through atomic replacement or rollback. This publication weakness predates the PR and is not retained as a new architecture concern.

Hardening Proposals

• proposed — Define which network aggregates are intentionally public and which remain subject to foreign-guild intelligence restrictions. Apply that classification consistently to player and map projections, accounting for the economic information already exported.

43-71: 🚀 Performance & Scalability | 🔵 Trivial

Open the network list on the main thread only, or cache the summaries.

Each call to open runs CurrentNetworks.from. That call evaluates the trade lookup once for every pair of guild and network province. Every page change runs this work again. The cost is acceptable at the current scale. If the number of guilds or provinces grows large, compute the summaries once per snapshot and reuse them.
