+## Legacy Source Cleanup — Pass 1 (Non-Destructive)
+
+**Date:** 2026-04-05
+**Branch:** cleanup/legacy-source
+**Type:** Non-destructive archive + tombstone cleanup
+
+### Summary
+Performed a conservative source cleanup to reduce ambiguity for AI agents and developers.
+Focused on isolating legacy code paths and removing confirmed placeholder/tombstone artifacts without impacting the active runtime path.
+
+---
+
+### Actions Taken
+
+#### 1. Legacy Orders System Archived
+The `NT8.Core.Orders` namespace was explicitly marked as archived and superseded by `NT8.Core.OMS`.
+
+Moved to:
+- `src/_archive/legacy-orders/`
+  - `IOrderManager.cs`
+  - `OrderManager.cs`
+  - `OrderModels.cs`
+
+Paired test moved with source:
+- `tests/_archive/legacy-orders/OrderManagerTests.cs`
+
+Rationale:
+- Prevents compile/runtime confusion between legacy Orders and active OMS
+- Prevents tests from referencing removed implementation paths
+- Ensures AI agents do not target deprecated order management logic
+
+---
+
+#### 2. Placeholder Source Files Archived
+Moved to:
+- `src/_archive/placeholders/`
+  - `PlaceholderAdapter.cs`
+  - `PlaceholderContract.cs`
+  - `PlaceholderStrategy.cs`
+
+Rationale:
+- These files contain no meaningful implementation
+- They create false signal for AI-assisted development
+
+---
+
+#### 3. Placeholder Test Files Archived
+Moved to:
+- `tests/_archive/placeholders/`
+  - `Integration_PlaceholderTests.cs`
+  - `Performance_PlaceholderTests.cs`
+
+Deleted:
+- `tests/NT8.Integration.Tests/UnitTest1.cs`
+- `tests/NT8.Performance.Tests/UnitTest1.cs`
+
+Rationale:
+- Placeholder tests (`Assert.IsTrue(true)`) provide no coverage
+- They distort test signal and can mislead analysis workflows
+
+---
+
+#### 4. Tombstone / Dead Files Removed
+Deleted (confirmed comment-only or empty artifacts):
+- `src/NT8.Adapters/Class1.cs.bak`
+- `src/NT8.Contracts/Class1.cs`
+- `src/NT8.Strategies/Class1.cs`
+
+Rationale:
+- Files contained no executable logic
+- Safe removal reduces noise and ambiguity
+
+---
+
+### Deferred / Blocked Items
+
+These files were intentionally **not modified** in this pass due to active references or ambiguity:
+
+- `src/NT8.Adapters/Wrappers/BaseNT8StrategyWrapper.cs`
+- `src/NT8.Adapters/Wrappers/SimpleORBNT8Wrapper.cs`
+- `src/NT8.Core/Risk/RiskManager.cs`
+- `src/NT8.Adapters/NinjaTrader/NT8Adapter.cs`
+- `src/NT8.Core/Class1.cs.bak` (contains real code, not a tombstone)
+
+Status:
+- Blocked pending second cleanup pass
+
+Reason:
+- Wrapper layer has test dependencies that must be migrated or rewritten before archiving
+- Some files contain real logic and require classification (active vs legacy) before removal
+
+---
+
+### Verification
+
+- `verify-build.bat`: **PASS**
+- All tests passing:
+  - Core: 393/393
+  - Integration: 78/78
+  - Performance: 10/10
+
+No compile errors or regressions introduced.
+
+---
+
+### Impact
+
+- Eliminated legacy order management ambiguity
+- Reduced AI hallucination risk in source selection
+- Removed non-functional placeholder code and tests
+- Preserved full build and test integrity
+
+---
+
+### Follow-Up Actions
+
+1. Second cleanup pass:
+   - Wrapper layer isolation or migration
+   - RiskManager classification
+   - NT8Adapter classification
+   - Resolve `Class1.cs.bak` ambiguity
+
+2. Metrics vocabulary extraction:
+   - Duplicate metrics definitions exist in:
+     - `backtest_review_workflow.md`
+     - `live_test_review_workflow.md`
+   - Planned extraction target:
+     - `docs/00-governance/metrics_vocabulary.md`
+
+3. Optional:
+   - Introduce `src/_archive/experimental/` if needed for future isolation
+
+---
+
+### Notes
+
+- No protected runtime paths were modified
+- No namespaces or interfaces were changed
+- No `.csproj` files were modified
+- All changes were reversible via archive structure
+
+Pass 2 removed:
+src/NT8.Core/Risk/RiskManager.cs
+src/NT8.Core/Class1.cs.bak
+wrappers + NT8Adapter.cs + wrapper-dependent tests/docs remain deferred as a grouped cluster
+future pass must handle:
+BaseNT8StrategyWrapper.cs
+SimpleORBNT8Wrapper.cs
+NT8Adapter.cs
+NT8WrapperTests.cs
+wrapper-dependent parts of NT8IntegrationTests.cs
+historical docs that still reference wrapper deployment

+   - Net Profit
+   - Profit Factor
+   - Max Drawdown
+   - Win Rate
+   - Average Trade
+   - Expectancy
+   - Trade Count
+4. Check risk behavior consistency (drawdown shape, loss clustering, streak behavior).
+5. Compare against prior baseline and flag material regressions.
+6. Record decision: `pass`, `pass_with_conditions`, or `fail`.
+
+## Required Output
+- Backtest Review Note with:
+  - metadata,
+  - metrics snapshot,
+  - baseline delta,
+  - decision,
+  - required follow-ups.
+
+## Exit Criteria

+# Compile Error Triage Workflow
+
+## Purpose
+Resolve compile errors quickly using smallest-safe changes and durable prevention notes.
+
+## Inputs
+- Failing command output (`./verify-build.bat` or `dotnet test`).
+- File scope constraints for current task.
+
+## Steps
+1. Reproduce with the same command to confirm current error set.
+2. Classify each error:
+   - missing type/namespace,
+   - bad override/signature,
+   - wrong overload/argument,
+   - C# 5.0 compatibility violation.
+3. Verify any NinjaScript/API signatures against NT8 docs before editing.
+4. Apply minimum-diff fix in scoped files only.
+5. Re-run `./verify-build.bat`.
+6. Run focused tests for the impacted area.
+7. If issue is non-trivial, add concise prevention notes to governance docs.
+
+## Required Output
+- Error-to-fix mapping (error code, root cause, fix).
+- Verification evidence (build/test commands and results).
+
+## Exit Criteria
+- Build passes.
+- Relevant tests pass.
+- Non-trivial learnings are captured.

+
+## Tool Handoffs and Artifact Passing
+1. **Spec Intake (Planner)**
+   - Tool: Archon task/project view.
+   - Input artifact: approved spec text.
+   - Output artifact: `Task Brief` containing objective, scope, constraints, acceptance criteria.
+2. **Task Breakdown (Planner)**
+   - Tool: Archon task board.
+   - Input artifact: `Task Brief`.
+   - Output artifact: ordered subtasks with file scope and done criteria.
+3. **Implementation (Implementer)**
+   - Tool: repository editor + scoped files.
+   - Input artifact: ordered subtasks.
+   - Output artifact: minimal code/doc diffs limited to allowed files.
+4. **Build Verification (Verifier)**
+   - Tool: `./verify-build.bat`.
+   - Input artifact: working tree changes.
+   - Output artifact: pass/fail result with error details if failed.
+5. **Focused Tests (Verifier)**
+   - Tool: `dotnet test` with area filter.
+   - Input artifact: verified build output.
+   - Output artifact: test evidence (command + pass/fail + failing test IDs).
+6. **Task State Update (Planner/Implementer)**
+   - Tool: Archon task board.
+   - Input artifact: verification evidence.
+   - Output artifact: task moved `doing` -> `review` with implementation notes and evidence links.
+
+## Required Artifact Bundle for Review
