fix: bind research menus to their own station

[XxFran10xX]

A player who owned more than one research station could act on the wrong one (reported by Dref: "Research station/data needs to be separated per station so a user can have multiple stations at once").

Station data was already stored per lectern; the problem was the menu session. Opening the scrap confirmation fires an inventory close for the station menu, which cleared the player's open-station entry. Clicks then fell back to the first station the player owned, so Scrap → Yes on one station could delete another station's project, and No reopened the wrong station.

Each station menu and scrap confirmation now carries its lectern location in a StationMenuHolder, and clicks resolve the station from the menu that is open. The per-player open-station map and its first-owned-station fallback are removed. Breaking or scrapping a station only closes that station's own menu.

Validation: mvn clean verify passes (5 tests). The new MultipleStationsTest fails on the old code (the other station is scrapped) and passes with the fix. The jar loaded cleanly on TFMCDev01 with its full config and no Research warnings. No in-game two-station playtest yet.

Summary by CodeRabbit

• Bug Fixes
  • Research menus now stay associated with the station they were opened for, preventing actions in one station’s menu from affecting another.
  • Scrap confirmations apply only to the selected station, and the corresponding menu closes when that station is scrapped.
  • Menu actions no longer fall back to another owned station when the selected station can’t be found or accessed.

📝 Walkthrough

Walkthrough

Research menu inventories now identify their station through a StationMenuHolder. ResearchManager resolves menu actions from the open inventory, checks station ownership, and closes a menu during scrapping only when it identifies the station being scrapped.

Changes

Station Menu Ownership

Layer / File(s)	Summary
Attach station locations to menus src/main/java/net/tfminecraft/research/manager/StationMenuHolder.java, src/main/java/net/tfminecraft/research/manager/InventoryManager.java	StationMenuHolder stores a station location and inventory. Main and scrap-confirm inventories use a holder associated with their station.
Resolve menu actions and scrap targets src/main/java/net/tfminecraft/research/manager/ResearchManager.java, src/test/java/net/tfminecraft/research/manager/MultipleStationsTest.java, src/test/java/net/tfminecraft/research/manager/ResearchRefundTest.java	ResearchManager resolves stations from menu holders and checks ownership. Scrapping closes a menu only when its holder identifies the station. Tests cover scrapping one of two owned stations and use a holder in refund-test setup.

Merge Risk: ⚪ Minimal · up to ac1bd

No actionable issue remains before merge based on the supplied evidence. An in-game two-station check has not been reported.

Security Architecture Review

Security architecture risk: 🔵 Low · up to ac1bd

The menu now stays bound to its station, and ownership is checked before menu actions run. This reduces the risk of scrapping the wrong station. No new cross-player menu access is evident, though live two-station behavior and block-break protection remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — For menu-driven actions, the independently reachable target is limited to an existing station owned by the clicking player and identified by that menu. The previous fallback could instead select another station owned by the same player.

Trust Boundaries and Controls

• observed — The player-controlled inventory-click path cancels clicks in research menus, then requires a holder-derived station that exists and has the clicking player’s UUID before dispatching station actions.
• observed — Block breaking is a separate route to station deletion. Its handler has no local breaker-ownership check; the evidence does not establish whether server-side protection authorizes the break. This route predates the changed menu binding and is not established as a PR-introduced exposure.

Resilience and Maintainability Implications

• inferred — After a station is removed, a repeated click using its old menu cannot resolve that station from the in-memory station list. Menu closure also leaves an unrelated station menu open rather than closing it as part of another station’s deletion.

Hardening Proposals

• proposed — Verify and document the server policy that authorizes block breaks before station deletion, or enforce that authorization locally if no such policy exists. This is a separate, unverified pre-existing path, not a finding introduced by the menu change.

_{A rabbit checks the menu’s place,
And finds the station by its trace.
The right one leaves, the first stays near,
Its holder keeps the target clear.
Soft paws approve the tested way,
Then hop back through the fields to play.}
