-Before modifying any code, an agent must execute this sequence:
-
-1.  **Check `jars/`**: Verify the target API JARs (Paper, Folia, Velocity, etc.) are present.
-2.  **Verify `generated/`**: Check `src/main/java/org/mockmc/mockmc/generated/` to see the current automated surface.
-3.  **Run Compilation**: Execute `./gradlew compileJava` to establish a baseline and **log any pre-existing warnings**.

+# MockMC Agentic Workflow Protocol
+
+Autonomous protocol for scaling functional test coverage.
+
+## 🤖 Agent Roles
+
+### 1. Auditor (Discovery)
+- **Goal**: Identify gaps in functional testing.
+- **Workflow**:
+    - Scan `src/main/java/.../` for manual mocks.
+    - Check `src/test/java/` for corresponding `*MockTest.java`.
+    - Flag "Mechanical-Only" classes (only `BaseMockTest` present).
+
+### 2. Architect (Contract)
+- **Goal**: Define "Functional" state for target API.
+- **Workflow**:
+    - Inspect Paper/Velocity API JARs for stateful methods.
+    - Produce `TEST_PLAN.md` outlining logic scenarios.
+
+### 3. Coder (Implementation)
+- **Goal**: Author test suite and behavior logic.
+- **Workflow**:
+    - Implement JUnit 5 tests based on `TEST_PLAN.md`.
+    - Author behavior in manual mock if mechanical base is insufficient.
+    - Verify via `./gradlew test`.
+
+## 🚀 Execution Loop
+
+1. **TRIGGER**: Manual mock updated or class mirrored.
+2. **AUDIT**: Confirm missing functional tests.
+3. **DESIGN**: Produce `TEST_PLAN.md`.
+4. **BUILD**: Implement tests and logic.
+5. **VERIFY**: Run `./gradlew test`.

+# Handoff Notes: MetaMiner Refactoring & Technical Debt Cleanup
+
+## 📌 Context
+
+Completed a maintenance cycle on the MetaMiner engine to resolve IDE-reported warnings, reduce cognitive complexity, and fix unnecessary suppressions in generated mock interfaces.
+
+## ✅ Completed in this Session
+
+- **`BaseMockGenerator.java`**:
+    - Extracted helper methods for quirk processing and suppression logic (Complexity reduced from 18+ to within limits).
+    - Introduced constants for recurring JSON keys (`METHOD_QUIRKS`, `REPLACEMENT`).
+    - **Crucial Fix**: Removed redundant `@SuppressWarnings("deprecation")` on method implementations that were only deprecated themselves. Suppression is now surgically applied only if the return/parameter types are deprecated.
+- **`BaseTestGenerator.java`**:
+    - Modularized class scanning and class loading.
+    - Simplified safe-default check logic.
+    - Updated logging to follow JUL best practices.
+- **`CoverageReportGenerator.java`**:
+    - Modularized method counting.
+    - Switched to platform-neutral line separators (`%n`).
+- **API Mirroring**: Successfully regenerated 13,733 methods across all platforms (Bukkit, Paper, Velocity, Bungee) with 100% mechanical coverage.
+- **Verification**: Verified that `CommandManagerBaseMock.java` (Velocity) and others are now clean of "Unnecessary @SuppressWarnings" warnings. Full compilation build succeeded.
+
+## 🛠 Status of Phase 4
+
+- **DCE (Dead Code Elimination)**: Complete.
+- **Generator Polish**: Complete.
+- **Next Steps**: Transition to **Functional Depth**. The engine is now "clean" and stable, providing a high-fidelity mechanical mirror. The focus should shift to manual behavior implementation for complex entities (Warden, Bee, etc.) as outlined in `TODO.md`.
+
+## ⚠️ Notes for Next Agent
+
+- **Stale IDE Metadata**: You may occasionally see ghost errors (like syntax errors on comments) in the `current_problems` metadata due to IDE lag during massive file regenerations. Always trust `./gradlew compileJava` as the source of truth.
+- **LinkageErrors**: The generators now explicitly catch `LinkageError` during reflection to gracefully skip classes with unresolvable dependencies in the provided JARs. Check logs for warnings if specific classes aren't appearing in the mirror.
+- **Spotless**: Always run `./gradlew spotlessApply` after regeneration to ensure consistent formatting (tabs vs. spaces) as the generators output raw JavaPoet code which might differ slightly from the project's formatting rules.
