Problem

Pumps did nothing. SinkableHull uses a pump to set its sink threshold (100 - power, max 80) and to drain flooding faster, but setPump was never called outside tests. Every boat took on water below 80% hull health whatever its pump, and repaired boats drained 1 point per slow tick.

Live boats with pumps: cruiser, ironclad, sloop, torpedoboat (power 50 each). Gunboat has a sinkable hull but no pump, so it keeps the 80% threshold.

Change

• ComponentHandler links the vehicle's pump to its sinkable hull when it builds a template or a live vehicle.
• A pump below 10 power (e.g. power 50 under 20% health) now drains at least 1 per tick, the no-pump rate. Before, integer division gave 0, so a linked but badly damaged pump would have kept the boat flooded forever.

Balance effect

This is a balance change. With a healthy power-50 pump:

• a boat starts taking on water below 50% hull health instead of 80%;
• once the hull is above that line, flooding drains 5 per slow tick instead of 1.

Damaging the pump lowers its power and raises the threshold back toward 80%. A destroyed pump behaves like no pump. Decay rules with keep-afloat now stop hulls at the pump's threshold, as VehicleHealthDecay already expected. Main has no decay rules.

Tests

• Template and live handlers link the pump; a sinkable hull with no pump stays unpumped.
• A power-0 pump drains at the no-pump rate.
• mvn verify locally: 1742 tests pass. The coverage gate reports only lines covered by POSIX-permission tests, which are skipped on Windows.
• Dev (PR build on TFMCDev01): three sloops in a pool with stored damage set while Dev was stopped, then a bot boarded each:
  • hull 65%, healthy pump: no flooding (the old code floods below 80%);
  • hull 45%, healthy pump: floods, and in a first run sank (cause=SINK);
  • hull 75%, pump at 20% (power 10): floods.

📝 Summary

Summary by CodeRabbit

• Bug Fixes
  • Improved sinking recovery so sink progress decreases reliably when a hull is above its sinking threshold, including with a zero-power pump.
  • Sinkable hulls now correctly connect to their configured pumps across construction and vehicle-copy scenarios.
  • Sinkable hulls without a pump remain unaffected.

The component handler now links configured pumps to sinkable hulls. When the hull is not below its sink threshold, pump-assisted recovery reduces sink progress by at least one per tick.

Changes: Sinkable hull pump recovery

Layer / File(s)	Summary
Link pumps to sinkable hulls src/main/java/net/tfminecraft/vehicleframework/vehicles/handlers/ComponentHandler.java, src/test/java/net/tfminecraft/vehicleframework/vehicles/handlers/VehicleHandlersCoverageTest.java	The handler links the pump to a sinkable hull after configuration-based and vehicle-copy construction. Tests check pump references on templates and live instances, and check that hulls without a configured pump remain unpumped.
Enforce minimum sink-progress reduction src/main/java/net/tfminecraft/vehicleframework/vehicles/component/SinkableHull.java, src/test/java/net/tfminecraft/vehicleframework/vehicles/component/VehicleComponentsCoverageTest.java	Pump-assisted recovery now decreases sink progress by at least one per tick. A test checks that a zero-power pump decreases progress from two to one after hull damage is cleared.

219-228: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Cover the production construction paths for pump linking.

VehicleHandlersCoverageTest calls both ComponentHandler constructors directly. It does not verify the arguments supplied by VehicleLoader or the real ActiveVehicle constructor. Current loader coverage uses a non-sinkable hull, and spawner coverage mocks ActiveVehicle. A regression at either boundary could leave a sinkable hull without its pump while these assertions remain green. The pump-dependent sinking threshold and flooding drainage would then be absent.

Add focused tests that load a sinkable vehicle through VehicleLoader and construct a real live vehicle, asserting that each hull references its configured pump. This is a targeted regression guard, not a claim that the current implementation fails.
