+# Hunting worker-slot config merge fix
+
+- Time: `2026-07-27 15:38:45 +0800`
+- Author: `Codex; OpenAI GPT-5; primary agent /root`
+- Status: `completed`
+- Scope: `HuntingBaseBlockEntity worker-slot calculation`
+
+## Completed
+
+- Restored the hunting-base worker-slot calculation lost during the scope merge.
+- Effective floor area is once again divided by `HUNTING.floorBlocksPerWorkerSlot`, and the result is bounded by `HUNTING.minimumWorkerSlots`.
+
+## Decisions
+
+- Preserve the existing effective-floor-area formula and integer truncation while replacing only the regressed hard-coded values.
+- Leave the unrelated `SimpleItemKey` merge error unchanged because it is outside this requested fix.
+
+## Validation
+
+- `git diff --check` passed.
+- `./gradlew compileJava --offline` succeeded in the existing temporary review copy after removing its known `SimpleItemKey` extra-brace blocker; only the repository's existing 20 deprecation warnings remained.
+
+## Remaining
+
+- The main working tree still cannot compile until the unrelated extra closing brace in `SimpleItemKey.java` is fixed.
