What

Adds a max_yield(N) production-method effect that caps a node's final items per cycle, and gives the Artifact Mine focus max_yield(1).

Artifact Mines now always produce exactly one artifact per cycle, whatever tool is fitted. Better tools still shorten the cycle. Every other node keeps its tool yield bonus unchanged.

Why

Artifact Mines have a base yield of 1 (the level's yield(1); the focus adds none). On Main, abyssalite and mythril tools add yield_percent(80/120), which rounds that up to 2 artifacts per cycle. Magic mines share the tool slot with Dust Mines, so the tool yield couldn't be removed for Artifact Mines alone in config.

How

• Node.runEffect: max_yield(N) sets a cap. The lowest cap wins when several PMs set one.
• Node.update: clears the cap before re-applying effects, so switching to an uncapped focus removes it.
• Node.getYield: returns min(normal yield, cap), never below 0. ItemDropper and the node GUI's "Yield:" line both use it.
• ItemCreator.getFormattedEffect: shows Max Yield: N in PM lore.
• Default production_methods.yml: artifact_focus gets max_yield(1). Existing servers need the line added to their own config.

A cycle rolled before the cap existed, held as a pending result, still delivers its saved output once. No live Artifact Mine currently rolls more than 1.

Tests

• NodeBehaviorTest: the cap limits a percent bonus, the lowest cap wins, a negative cap clamps to 0, an Artifact focus plus a +120% tool gives 1, and switching to a Dust focus clears the cap (13).
• ItemCreatorTest: max_yield(1) lore.
• Local mvn verify: all tests pass except DatabaseTest and NodePaymentsTest, which fail identically on main on Windows (directory fsync). Node and ItemCreator have no uncovered lines.
• Dev (TFMCDev01), this build with max_yield(1) added to Dev's artifact_focus, two test nodes with mythril tools (Dev's mythril is flat yield(3)):
  • Artifact Mine: 1 artifact in the hopper (would be 4 uncapped).
  • Dust Mine: 8 Enchanted Dust (1 + 4 + 3, unchanged).

📝 Summary

Summary by CodeRabbit

• New Features
  • Added support for effects that set a maximum yield. When multiple caps apply, the lowest one is used.
  • Artifact Focus now limits yield to one, regardless of tool bonuses.
  • Maximum-yield effects are displayed as “Max Yield” in item descriptions.
• Bug Fixes
  • Negative maximum-yield values now result in zero yield, and changing to an uncapped focus clears the previous cap.

The change adds a max_yield effect that caps node yield, resets the cap when node effects are recalculated, and configures artifact focus with a cap of one. Effect formatting and tests also cover the new effect.

Changes: Maximum yield cap

Layer / File(s)	Summary
Apply maximum-yield effects src/main/java/net/tfminecraft/dowsing/objects/Node.java, src/test/java/net/tfminecraft/dowsing/objects/NodeBehaviorTest.java	Node retains the lowest configured max_yield value and limits calculated yield to that non-negative cap. It clears the cap during effect recalculation. Tests cover cap selection, negative values, and clearing the cap when the focus changes.
Configure and format the cap src/main/resources/production_methods.yml, src/main/java/net/tfminecraft/dowsing/utils/ItemCreator.java, src/test/java/net/tfminecraft/dowsing/utils/ItemCreatorTest.java	artifact_focus gains max_yield(1). Effect formatting displays the value as “Max Yield”, with a test for max_yield(1).

Add a configuration-backed test for artifact_focus.

The new test supplies max_yield(1) through a mocked ProductionMethod. It passes even when the shipped artifact_focus entry is removed or misspelled. The loader tests use synthetic YAML and do not validate this production entry. Add a test that loads src/main/resources/production_methods.yml, resolves artifact_focus, and asserts max_yield(1).
