-ALWAYS verify with the live Ninjascript reference available on the web at https://developer.ninjatrader.com/docs/desktop before making final edits.
-
-This third file confirms a recurrence of CS0246 compiler errors in VWAP_Pro.cs, specifically related to undefined types like ModeType and AnchorModeType.
-
-🔍 CS0246 - "The type or namespace name 'X' could not be found"
-Line	Column	Missing Type
-371	28	ModeType
-371	43	AnchorModeType
-391	39	ModeType
-391	54	AnchorModeType
-376	51	ModeType
-✅ How to Fix It
-🔧 1. Define Missing Enums (Recommended Fix)
-
-It seems that ModeType and AnchorModeType are custom enums that were expected to exist in the code but were never declared.
-
-Create a separate file or include this in the same VWAP_Pro.cs file near the top:
-
-public enum ModeType
-{
-    Standard,
-    Aggressive,
-    Conservative
-}
-
-public enum AnchorModeType
-{
-    SessionStart,
-    FixedTime,
-    Custom
-}
-
-
-You’ll need to customize the enum values (Standard, Aggressive, etc.) to match your strategy logic. These names are placeholders based on typical VWAP settings.
-
-🔧 2. OR Add Missing using Directives
-
-If these types exist in another NinjaTrader script or add-on you've imported before, ensure you include the right namespace:
-
-using NinjaTrader.NinjaScript.AddOns.MyVWAPEnums; // Example
-
-
-But since these errors suggest the types are completely undefined, it's much more likely they are simply not declared anywhere.
-
-🔧 3. Verify File Inclusion in NinjaTrader
-
-If these enums are defined in another file (e.g., VWAPTypes.cs), make sure:
-
-It's saved in the same directory as VWAP_Pro.cs
-
-It's added to the NinjaScript Editor, not just sitting in the file system
-
-You can add it using:
-
-Tools > NinjaScript Editor > Right-click > Add > Existing Item...
-
-🧼 Suggested Organization
-
-If these enums are used across multiple indicators/strategies, you should centralize them:
-
-VWAP_Enums.cs
-
-namespace NinjaTrader.NinjaScript.VWAP
-{
-    public enum ModeType
-    {
-        Standard,
-        Aggressive,
-        Conservative
-    }
-
-    public enum AnchorModeType
-    {
-        SessionStart,
-        FixedTime,
-        Custom
-    }
-}
-
-
-Then use:
-
-using NinjaTrader.NinjaScript.VWAP;
-
-
-
-These are occurring in VWAP_Pro.cs, mainly on lines 132–134:
-
-Line	Error Message (Truncated)
-132	Argument 2: cannot convert from 'int' to 'NinjaTrader.Gui.Tools.SimpleFont'
-132	Argument 3: cannot convert from 'NinjaTrader.Gui.Tools.SimpleFont' to 'System.Windows.Media.Brush'
-133	Same as above
-134	Same as above
-🔧 Interpretation:
-
-It looks like a method (likely a drawing method like Draw.Text() or Draw.TextFixed()) is being called with the wrong argument types — specifically:
-
-An int is being passed where a SimpleFont is expected.
-
-A SimpleFont is being passed where a Brush is expected.
-
-This suggests that arguments are out of order or misassigned.
-
-✅ Proper Fix
-
-Let’s consider the proper usage of Draw.Text() in NinjaTrader 8:
-
-Draw.Text(NinjaScriptBase owner, string tag, bool isAutoScale, string text, int barsAgo, double y, Brush textBrush, SimpleFont font, TextAlignment alignment, Brush outlineBrush, int outlineWidth);
-
-
-Or for simpler usage:
-
-Draw.Text(this, "tag1", "Hello", 0, Close[0], Brushes.White);
-
-
-Your issue likely looks like this:
-
-Draw.Text(this, "tag1", true, "Label", 0, 100, 12, someFont, ...);
-
-
-Where 12 (int) is mistakenly passed as a font or brush, causing the error.
-
-🔧 Corrected Example:
-
-Assuming you want to draw text with a specific font and color:
-
-SimpleFont font = new SimpleFont("Arial", 12);
-Draw.Text(this, "tag1", true, "VWAP Label", 0, Close[0], Brushes.White, font, TextAlignment.Center, Brushes.Black, 1);
-
-
-Brushes.White → text color
-
-font → SimpleFont object
-
-TextAlignment.Center → alignment
-
-Brushes.Black → outline brush
-
-1 → outline width
-
-✅ Steps to Fix:
-
-Replace the integer (e.g., 12) with a SimpleFont:
-
-new SimpleFont("Arial", 12)
-
-
-Ensure arguments are in the correct order:
-Double-check the method signature from the NinjaTrader 8 Help Guide
-.
-
-Use Brushes for colors, not fonts.
-
-
-
-
-
-
-Summary of Errors:
-Line	Column	Missing Type
-403	39	ModeType
-403	54	AnchorModeType
-408	63	ModeType
-408	78	AnchorModeType
-367	28	ModeType
-✅ Fixes:
-
-These types — ModeType and AnchorModeType — are not recognized. Here are the likely causes and solutions:
-
-🔍 1. Missing using Directive
-
-These types might be defined in a different namespace. If they are from a custom or NinjaTrader add-on:
-
-Fix: Add the appropriate using statement at the top of your file.
-
-Example:
-
-using NinjaTrader.NinjaScript.AddOns.VWAP;
-
-
-Adjust according to where ModeType and AnchorModeType are defined.
-
-🔍 2. Missing Class Definitions
-
-If they are not in any existing libraries, they might be custom enum types that should be defined in your project but are missing.
-
-Fix: Add enum declarations like these (if applicable):
-
-public enum ModeType
-{
-    Standard,
-    Aggressive,
-    Conservative
-}
-
-public enum AnchorModeType
-{
-    SessionStart,
-    FixedTime,
-    Custom
-}
-
-
-Only do this if you know what the enum values should be. These names are placeholders — you should match them with how your indicator/strategy is designed.
+# Compile Error Guidance - Reusable Protocol
+**Last Updated:** 2026-04-05
+
+Apply this protocol for all compile issues.
+
+## 1) Verify First
+- [ ] Verify exact NinjaScript/API signature against official NT8 docs before editing: `https://developer.ninjatrader.com/docs/desktop`.
+- [ ] Confirm file is in scope before making any change.
+
+## 2) Classify the Error
+- [ ] Missing type/namespace (e.g., `CS0246`).
+- [ ] Invalid override/signature/access modifier (e.g., `CS0115`, `CS0507`).
+- [ ] Argument mismatch or wrong overload (e.g., `CS1503`).
+- [ ] C# language version incompatibility (C# 6+ syntax in C# 5 project).
+
+## 3) Apply Smallest Safe Fix
+- [ ] Prefer minimal edits in scoped files only.
+- [ ] Fix root cause, not symptom chaining.
+- [ ] Preserve existing architecture/contracts unless task explicitly requires change.
+
+## 4) Re-Run Verification
+- [ ] Run `.\verify-build.bat`.
+- [ ] Run required tests for changed area.
+- [ ] If NinjaScript touched, run NT8 compile check in NinjaScript Editor.
+
+## 5) Capture Durable Learning
+For non-trivial compile failures, add concise entries to:
+- [ ] `docs/00-governance/common_failures.md` (error fingerprint + fix).
+- [ ] `docs/00-governance/compile_guardrails.md` (prevention rule).
+- [ ] `docs/00-governance/patterns_and_antipatterns.md` (good vs bad pattern).
+
+## Do Not
+- [ ] Do not guess signatures, overloads, enums, or attributes.
+- [ ] Do not invent placeholder enums/types unless confirmed by domain/task requirements.
+- [ ] Do not keep one-off incident dumps in this rule file; store incidents in `common_failures.md`.

-# Coding Patterns — NT8 SDK Required Patterns
-**Last Updated:** 2026-03-27
+# Coding Patterns - NT8 SDK Required Patterns
+**Last Updated:** 2026-04-05
 
-All code in the NT8 SDK MUST follow these patterns without exception.
+All production code must use these implementation patterns.
 
----
+## Scope Discipline and Minimum Diff
+- [ ] Edit only files in task scope.
+- [ ] Make the smallest safe change that resolves the issue.
+- [ ] Do not change interfaces/contracts unless explicitly required.
+- [ ] Do not mix functional changes with style-only cleanup.
 
-## 0. C# 5.0 Hard Constraints (NinjaScript Compiler)
+## C# 5.0 and .NET 4.8 Compatibility
+- [ ] Use C# 5.0 syntax only.
+- [ ] Avoid C# 6+ features (`$""`, `?.`, `nameof`, expression-bodied members, `out var`, etc.).
+- [ ] Keep compatibility with .NET Framework 4.8.
+- [ ] Use `string.Format` style logging/messages.
 
-```csharp
-// ❌ PROHIBITED — compiler will fail silently or error
-$"Hello {name}"                    // no string interpolation
-obj?.Method()                      // no null-conditional
-public int Prop => _value;         // no expression body
-nameof(SomeClass)                  // no nameof
-await SomeAsync()                  // no async/await
+## Core Implementation Patterns
+- [ ] Validate inputs at method entry.
+- [ ] Wrap public method logic in `try/catch` with meaningful logging.
+- [ ] Protect shared mutable collections/state with `lock (_lock)`.
+- [ ] Do not raise events while holding locks.
+- [ ] Keep public members documented with XML comments where required by project standards.
 
-// ✅ REQUIRED
-string.Format("Hello {0}", name)
-obj != null ? obj.Method() : null
-public int Prop { get { return _value; } }
-"SomeClass"                        // string literal
-// synchronous only
-```
+## NinjaScript Coding Patterns (When Applicable)
+- [ ] Keep `OnStateChange` responsibilities separated by state.
+- [ ] Guard `OnBarUpdate` by `BarsInProgress` and bar readiness.
+- [ ] In managed order flow, set stop/target before entry on the same bar.
 
----
-
-## 0b. NT8-Specific Critical Rules
-
-```csharp
-// SetStopLoss/SetProfitTarget MUST come BEFORE EnterLong/EnterShort
-// Calling them after is silently ignored in backtest
-SetStopLoss(signalName, CalculationMode.Ticks, stopTicks, false);  // FIRST
-SetProfitTarget(signalName, CalculationMode.Ticks, targetTicks);   // SECOND
-EnterShort(qty, signalName);                                        // THIRD
-
-// OnBarUpdate must guard secondary series
-protected override void OnBarUpdate()
-{
-    if (BarsInProgress != 0) return;  // CRITICAL: ignore daily bar series updates
-    // ...
-}
-
-// State guard in ProcessStrategyIntent
-// Allows Historical (backtest), blocks Realtime replay burst:
-if (State == State.Realtime && !_realtimeBarSeen)
-    return;
-```
-
----
-
-## Sizing Formula
-
-```
-contracts = floor(RiskPerTrade / (StopTicks × TickValue))
-NQ tick value = $5.00
-$100 / (8 × $5) = 2 contracts
-$200 / (8 × $5) = 5 contracts (capped at MaxContracts)
-Always verify: RiskPerTrade ≤ MaxTradeRisk
-```
-
----
-
-## 1. Thread Safety — Lock Everything Shared
-
-Every class with shared state must have a lock object:
-```csharp
-private readonly object _lock = new object();
-```
-
-Every access to shared `Dictionary`, `List`, `Queue`, or any field touched by multiple threads:
-```csharp
-// ❌ NEVER
-_activeOrders[orderId] = status;
-
-// ✅ ALWAYS
-lock (_lock)
-{
-    _activeOrders[orderId] = status;
-}
-```
-
-### Read-then-write must be atomic
-```csharp
-// ❌ WRONG — race condition between check and write
-if (!_orders.ContainsKey(id))
-    _orders[id] = newOrder;
-
-// ✅ CORRECT
-lock (_lock)
-{
-    if (!_orders.ContainsKey(id))
-        _orders[id] = newOrder;
-}
-```
-
----
-
-## 2. Error Handling — Try-Catch on All Public Methods
-
-```csharp
-public ReturnType MethodName(Type parameter)
-{
-    // 1. Validate parameters first
-    if (parameter == null)
-        throw new ArgumentNullException("parameter");
-
-    // 2. Wrap the main logic
-    try
-    {
-        // Implementation
-        return result;
-    }
-    catch (SpecificException ex)
-    {
-        _logger.LogError("Specific failure in MethodName: {0}", ex.Message);
-        throw;
-    }
-    catch (Exception ex)
-    {
-        _logger.LogError("Unexpected failure in MethodName: {0}", ex.Message);
-        throw;
-    }
-}
-```
-
----
-
-## 3. Logging — Always string.Format, Never $""
-
-```csharp
-// ❌ NEVER — C# 6 syntax, breaks NT8 compile
-_logger.LogInformation($"Order {orderId} filled");
-
-// ✅ ALWAYS
-_logger.LogInformation("Order {0} filled", orderId);
-_logger.LogWarning("Risk check failed for {0}: {1}", symbol, reason);
-_logger.LogError("Exception in {0}: {1}", "MethodName", ex.Message);
-_logger.LogCritical("Emergency flatten triggered: {0}", reason);
-```
-
-### Log level guide
-| Level | When to use |
-|---|---|
-| `LogTrace` | Entering/exiting methods, fine-grained flow |
-| `LogDebug` | State reads, normal data flow |
-| `LogInformation` | Important events: order submitted, filled, cancelled |
-| `LogWarning` | Recoverable issues: validation failed, limit approaching |
-| `LogError` | Failures: exceptions, unexpected states |
-| `LogCritical` | System integrity issues: emergency flatten, data corruption |
-
----
-
-## 4. Events — Never Raise Inside Locks
-
-Raising events inside a lock causes deadlocks when event handlers acquire other locks.
-
-```csharp
-// ❌ DEADLOCK RISK
-lock (_lock)
-{
-    _state = newState;
-    OrderStateChanged?.Invoke(this, args);  // handler may try to acquire _lock
-}
-
-// ✅ CORRECT
-OrderState newState;
-lock (_lock)
-{
-    newState = CalculateNewState();
-    _state = newState;
-}
-// Raise AFTER releasing lock
-RaiseOrderStateChanged(orderId, previousState, newState);
-```
-
----
-
-## 5. Constructor — Validate All Dependencies
-
-```csharp
-public MyClass(ILogger<MyClass> logger, ISomeDependency dep)
-{
-    if (logger == null)
-        throw new ArgumentNullException("logger");
-    if (dep == null)
-        throw new ArgumentNullException("dep");
-
-    _logger = logger;
-    _dep = dep;
-
-    // Initialize collections
-    _activeOrders = new Dictionary<string, OrderStatus>();
-
-    _logger.LogInformation("MyClass initialized");
-}
-```
-
----
-
-## 6. XML Documentation — Required on All Public Members
-
-```csharp
-/// <summary>
-/// Brief one-line description of what this does.
-/// </summary>
-/// <param name="intent">The trading intent to validate.</param>
-/// <param name="context">Current strategy context with account state.</param>
-/// <returns>Risk decision indicating allow or reject.</returns>
-/// <exception cref="ArgumentNullException">Thrown when intent or context is null.</exception>
-public RiskDecision ValidateOrder(StrategyIntent intent, StrategyContext context)
-{
-    ...
-}
-```
-
----
-
-## 7. NT8-Specific Patterns (NinjaScript)
-
-When writing code that runs inside NinjaTrader (in `NT8.Adapters/`):
-
-```csharp
-// Always guard OnBarUpdate
-protected override void OnBarUpdate()
-{
-    if (BarsInProgress != 0) return;
-    if (CurrentBar < BarsRequiredToTrade) return;
-    // ...
-}
-
-// Managed order pattern — set stops BEFORE entry
-SetStopLoss("SignalName", CalculationMode.Ticks, stopTicks, false);
-SetProfitTarget("SignalName", CalculationMode.Ticks, targetTicks);
-EnterLong(contracts, "SignalName");
-
-// Use string.Format for Print() too
-Print(string.Format("Order submitted: {0} contracts at {1}", qty, price));
-```
-
----
-
-## 8. Checklist Before Marking Any Method Complete
-
-- [ ] Parameter null checks at the top
-- [ ] `try-catch` wrapping the body
-- [ ] All `Dictionary`/collection access inside `lock (_lock)`
-- [ ] All logging uses `string.Format()` (no `$""`)
-- [ ] XML `/// <summary>` on every public method, property, class
-- [ ] No C# 6+ syntax
-- [ ] Events raised outside lock blocks
-- [ ] `verify-build.bat` passes

-## Original Archon Workflow (2025, archived below)
-
-## Archon Workflow Principles
-
-The development process follows these core principles adapted from the Archon workflow:
-
-### 1. Check Current Task
-Before beginning any work, clearly define what needs to be accomplished:
-- Review requirements and specifications
-- Understand success criteria
-- Identify dependencies and blockers
-
-### 2. Research for Task
-Conduct thorough research before implementation:
-- Review existing code and documentation
-- Understand best practices and patterns
-- Identify potential challenges and solutions
-
-### 3. Implement the Task
-Execute the implementation with focus and precision:
-- Follow established patterns and conventions
-- Write clean, maintainable code
-- Include comprehensive error handling
-- Add structured logging for observability
-
-### 4. Update Task Status
-Track progress and document completion:
-- Mark tasks as completed in the todo list
-- Document any issues or deviations
-- Note lessons learned for future reference
-
-### 5. Get Next Task
-Move systematically through the implementation:
-- Prioritize tasks based on dependencies
-- Focus on one task at a time
-- Ensure quality before moving forward
-
-## Development Process
-
-### Phase 1: Planning and Design
-1. Review specifications and requirements
-2. Create architecture diagrams and documentation
-3. Identify core components and their interactions

-2. Set up build and test infrastructure
-3. Configure CI/CD pipeline
-4. Verify development environment
-
-### Phase 3: Core Implementation
-1. Implement core interfaces and models
-2. Develop risk management components
-3. Create position sizing algorithms
-4. Build supporting utilities and helpers
-
-### Phase 4: Testing and Validation
-1. Create comprehensive unit tests
-2. Implement integration tests
-3. Run validation scripts
-4. Verify all success criteria
-
-### Phase 5: Documentation and Delivery
-1. Create developer documentation

-Since we're not using the Archon MCP server, we'll manage tasks using:
-1. **Todo Lists**: Track progress using markdown checklists
-2. **Documentation**: Maintain detailed records of implementation decisions
-3. **Git**: Use commits and branches to track work progress
-4. **Issue Tracking**: Use GitHub Issues or similar for task management
-
-### Task Status Tracking
-- **Todo**: Task identified but not started
-- **In Progress**: Actively working on task
-- **Review**: Task completed, awaiting validation
-- **Done**: Task validated and completed
-
-## Communication and Collaboration
-
-### Team Coordination
-- Hold regular standups to discuss progress
-- Use collaborative tools for communication
-- Document architectural decisions
-- Share knowledge and best practices
-
-### Knowledge Sharing
-- Conduct code walkthroughs for complex features
-- Create technical documentation
-- Share lessons learned from issues
-- Mentor new team members
-
-## Conclusion
-
-This development workflow ensures consistent, high-quality implementation of the NT8 Institutional SDK. By following these principles and practices, we can deliver a robust, maintainable, and scalable trading platform that meets institutional requirements for risk management and performance.
-
-The workflow emphasizes systematic progress, quality assurance, and continuous improvement. Each task should be approached with thorough research, careful implementation, and comprehensive validation to ensure the highest quality outcome.
+# NT8-SDK Development Workflow
+**Last Updated:** 2026-04-05
+
+Operational workflow for Kilo/Codex-assisted development.
+
+## Per-Task Workflow (Required)
+1. **Confirm scope**
+   - [ ] Confirm exact files allowed by task spec.
+   - [ ] Cross-check `.kilocode/rules/file_boundaries.md`.
+2. **Set task state**
+   - [ ] Move task status from `todo` -> `doing` before edits.
+3. **Implement**
+   - [ ] Make minimum-diff changes only in scoped files.
+4. **Verify**
+   - [ ] Run `.\verify-build.bat` per `.kilocode/rules/verification_requirements.md`.
+   - [ ] Run focused tests required by changed area.
+5. **NT8 compile/deploy checks** (when NinjaScript files are touched)
+   - [ ] Validate signatures against official NT8 docs.
+   - [ ] Run repo build/deploy sequence required for NT8.
+   - [ ] Compile in NinjaScript Editor (authoritative NT8 check).
+6. **Documentation updates**
+   - [ ] Update `docs/00-governance/active_work.md` when task status or blockers changed.
+   - [ ] Update `docs/00-governance/roadmap.md` when sequencing/scope changed.
+   - [ ] Update `docs/00-governance/decisions.md` when durable architecture decisions were made.
+   - [ ] Update `CLEANUP_LOG.md` when cleanup debt status changed.
+7. **Compile-learning capture** (if any compile issue occurred)
+   - [ ] Add prevention rule to `docs/00-governance/compile_guardrails.md`.
+   - [ ] Add error fingerprint + fix to `docs/00-governance/common_failures.md`.
+   - [ ] Add pattern/anti-pattern to `docs/00-governance/patterns_and_antipatterns.md`.
+8. **Set task state and report**
+   - [ ] Move task status from `doing` -> `review`.
+   - [ ] Report changed files and verification evidence.
+
+## Definition of Done (Required)
+- [ ] Only scoped files changed.
+- [ ] Verification gates passed.
+- [ ] NT8 compile checks completed when relevant.
+- [ ] Relevant governance docs updated.
+- [ ] Compile learnings captured when applicable.
+- [ ] Task moved to `review` with evidence.
+
+## Out-of-Scope Safety
+- [ ] Do not modify files outside task scope.
+- [ ] Do not apply opportunistic refactors.
+- [ ] Do not modify historical/contextual docs unless explicitly requested.
+- [ ] If a real fix needs out-of-scope changes, stop and report a scope blocker.

+# Governance Docs Maintenance Policy
+**Last Updated:** 2026-04-05
+
+## Canonical Source Rule
+- [ ] `docs/00-governance/*` is the canonical planning and execution source.
+- [ ] Prefer updating canonical governance docs over duplicating guidance elsewhere.
+
+## Historical/Contextual Docs (Read-Only by Default)
+Treat these as non-canonical unless explicitly requested by task scope:
+- `README.md`
+- `docs/README.md`
+- `PROJECT_HANDOVER.md`
+- `DESIGNED_VS_IMPLEMENTED_GAP_ANALYSIS.md`
+- `docs/INDEX.md`
+
+## Update Triggers
+- [ ] Update `docs/00-governance/active_work.md` when priorities, status, blockers, or ownership change.
+- [ ] Update `docs/00-governance/roadmap.md` when milestone sequence, scope, or timing changes.
+- [ ] Update `docs/00-governance/decisions.md` when durable architecture tradeoffs/decisions are made.
+- [ ] Update `CLEANUP_LOG.md` when cleanup debt is created, resolved, or deferred.
+
+## Compile Knowledge Capture (Concise and Durable)
+When a compile issue occurs, record:
+- [ ] Prevention rule in `docs/00-governance/compile_guardrails.md`.
+- [ ] Error fingerprint + fix in `docs/00-governance/common_failures.md`.
+- [ ] Reusable pattern and anti-pattern in `docs/00-governance/patterns_and_antipatterns.md`.
+
+## Documentation Hygiene
+- [ ] Keep entries concise, actionable, and dated.
+- [ ] Link to authoritative rules instead of duplicating long guidance.
+- [ ] Do not update unrelated docs in the same task.

+# NinjaScript Guardrails - Operational Checklist
+**Last Updated:** 2026-04-05
+
+Use this checklist whenever touching NinjaScript-facing files.
+
+## Pre-Edit Checks (Required)
+- [ ] Confirm file is in task scope and allowed by `.kilocode/rules/file_boundaries.md`.
+- [ ] Verify exact API signatures against official NT8 docs: `https://developer.ninjatrader.com/docs/desktop`.
+- [ ] Confirm C# 5.0 compatibility using `.kilocode/rules/csharp_50_syntax.md`.
+
+## Lifecycle and Safety Rules (Required)
+- [ ] Use `OnStateChange` correctly: `State.SetDefaults`, `State.Configure`, `State.DataLoaded`.
+- [ ] Keep runtime logic out of `SetDefaults` and `Configure`.
+- [ ] Guard `OnBarUpdate` for series and readiness (`BarsInProgress`, `CurrentBar`/`CurrentBars`).
+- [ ] In managed order flow, set stop/target before entry on the same bar.
+- [ ] Do not mix managed and unmanaged order models unless explicitly required.
+
+## API Integrity Rules (Required)
+- [ ] Do not guess method signatures, enum members, attributes, or overloads.
+- [ ] Do not use unsupported attributes (example: `[Optimizable]`).
+- [ ] Do not invent placeholder types/enums unless explicitly confirmed by task/domain requirements.
+
+## Compile Validation Sequence
+- [ ] Run `.\verify-build.bat`.
+- [ ] Run required deploy step when NinjaScript source must be synced to NT8.
+- [ ] Compile in NT8 NinjaScript Editor (authoritative NinjaScript compile gate).
+
+## Compile Failure Learning Loop
+If any compile issue occurs:
+- [ ] Capture error fingerprint (`code`, file, line, root cause).
+- [ ] Apply the smallest safe fix and re-run validation sequence.
+- [ ] Record durable learning in:
+  - `docs/00-governance/common_failures.md` (symptom + fix)
+  - `docs/00-governance/compile_guardrails.md` (preventive rule)
+  - `docs/00-governance/patterns_and_antipatterns.md` (good vs bad pattern)

+# Project Context - NT8 SDK
+**Last Updated:** 2026-04-05
 
-You are working on the **NT8 SDK** — an institutional-grade algorithmic futures trading system for NinjaTrader 8.
-This is **production trading software**. Bugs cause real financial losses. Never take shortcuts.
+Mission: ship safe, compile-stable NT8 trading software with strict scope control and durable governance documentation.
 
----
+## Session Start (Mandatory)
+- [ ] Read these files first, in order:
+  1. `docs/00-governance/executive_summary.md`
+  2. `docs/00-governance/current_status.md`
+  3. `docs/00-governance/active_work.md`
+  4. `docs/00-governance/architecture.md`
+  5. `docs/00-governance/roadmap.md`
+- [ ] Treat `docs/00-governance/*` as canonical for current direction.
 
-## Critical Rules for Kilocode
+## Historical/Contextual Sources (Non-Canonical)
+Use only for background unless explicitly requested in task scope:
+- `README.md`
+- `docs/README.md`
+- `PROJECT_HANDOVER.md`
+- `DESIGNED_VS_IMPLEMENTED_GAP_ANALYSIS.md`
+- `docs/INDEX.md`
 
-1. **Only modify files listed in the task spec.** Never touch adjacent code.
-2. **C# 5.0 only.** No `$""`, no `?.`, no `=>` bodies, no `nameof()`, no async/await.
-3. **Never remove XML documentation or comments.**
-4. **Never change interface signatures** — IStrategy, IRiskManager, IPositionSizer, INT8ExecutionBridge are frozen.
-5. **Always build before deploying:** `dotnet build NT8-SDK.sln --configuration Release`
-6. **Always deploy to BOTH paths** after every code change:
-   - Repo: `C:\dev\nt8-sdk\src\NT8.Adapters\Strategies\`
-   - NT8: `C:\Users\billy\Documents\NinjaTrader 8\bin\Custom\Strategies\`
-7. **Never guess NT8 API signatures.** Verify at `https://developer.ninjatrader.com/docs/desktop`.
+## File Touch Scope (Hard Rules)
+- [ ] Modify only files explicitly listed in the task spec.
+- [ ] Do not edit adjacent files for cleanup or style-only changes.
+- [ ] If a required fix is outside scope, stop and record a scope blocker.
+- [ ] Respect `.kilocode/rules/file_boundaries.md` at all times.
 
----
+## Conversation Separation (Hard Rules)
+- [ ] Strategy conversations: entry/exit logic and behavior.
+- [ ] Architecture conversations: cross-component design and interfaces.
+- [ ] Coding conversations: implementation details and diffs.
+- [ ] Do not mix decisions across tracks; record architecture decisions in `docs/00-governance/decisions.md`.
 
-## Current State (2026-03-27)
+## Documentation Sync Triggers
+Update governance docs as part of normal task completion:
+- [ ] Update `docs/00-governance/active_work.md` when current priorities, status, blockers, or ownership change.
+- [ ] Update `docs/00-governance/roadmap.md` when milestone sequence, scope, or timing changes.
+- [ ] Update `docs/00-governance/decisions.md` when a durable tradeoff or architecture decision is made.
+- [ ] Update `CLEANUP_LOG.md` when cleanup debt is created, resolved, or deferred.
 
-**What works end-to-end:**
-- SimpleORBStrategy with 10-factor confluence scoring
-- NT8StrategyBase with session management, kill switch, connection recovery
-- Dual-leg scaler + runner architecture (EntriesPerDirection=2 restored)
-- PortfolioRiskManager singleton (kill switch, daily loss, contract cap)
-- File logging (session log + settings export)
-- Historical replay guard (_realtimeBarSeen)
-- Execution confirmed in SIM on 2026-03-27
-
-**Pending validation:**
-- Runner leg dual-fill (Qty=2) — run backtest to confirm
-- Breakeven + trail in live multi-bar scenario

-## What Is Already Built (Do Not Touch)
-
-All core trading logic is complete and has 240+ passing tests:
-
-| Layer | Status | Key Files |
-|---|---|---|
-| Risk (Tier 1-3) | ✅ Complete | `src/NT8.Core/Risk/` |
-| Position Sizing | ✅ Complete | `src/NT8.Core/Sizing/` |
-| OMS / Order Lifecycle | ✅ Complete | `src/NT8.Core/OMS/` |
-| Intelligence | ✅ Complete | `src/NT8.Core/Intelligence/` |

-**NT8 Order Execution is ALREADY WIRED.**
-`NT8StrategyBase.SubmitOrderToNT8()` calls `EnterLong`, `EnterShort`, `SetStopLoss`, and
-`SetProfitTarget` directly. The execution path works end-to-end. Do not re-implement it.
-
----
-
-## What You Are Fixing (The Active Task List)
-
-### CRITICAL — `NT8StrategyBase.cs`
-
-**Gap 1 — No kill switch**
-`NT8StrategyBase` has no `EnableKillSwitch` NinjaScript parameter and no early-exit in `OnBarUpdate()`.
-A runaway strategy cannot be stopped without killing NinjaTrader.
-**Fix:** Add `EnableKillSwitch` (bool NinjaScript property) and `EnableVerboseLogging` property.
-Add kill switch check as the FIRST thing in `OnBarUpdate()`.
-→ See `TASK-01-kill-switch.md`
-
-**Gap 2 — `ExecutionCircuitBreaker` not wired**
-`src/NT8.Core/Execution/ExecutionCircuitBreaker.cs` is complete and tested.
-It is never instantiated. Orders submit regardless of latency or rejection conditions.
-**Fix:** Instantiate in `InitializeSdkComponents()`, gate orders in `SubmitOrderToNT8()`, wire rejections in `OnOrderUpdate()`.
-→ See `TASK-02-circuit-breaker.md`
-
-### HIGH — `TrailingStopManager.cs`
-
-**Gap 3 — Placeholder stop math returns zero**
-`CalculateNewStopPrice()` FixedTrailing branch: `marketPrice - (x - x)` = always zero movement.
-ATRTrailing and Chandelier also have meaningless placeholder formulas.
-**Fix:** Replace with real calculations using `TrailingStopConfig.TrailingAmountTicks` and `AtrMultiplier`.
-→ See `TASK-03-trailing-stop.md`
-
-### HIGH — `BasicLogger.cs`
-
-**Gap 4 — No log-level filter**
-Every log statement writes to console unconditionally. Cannot suppress debug noise in production.
-**Fix:** Add `MinimumLevel` property (defaults to `Information`). Suppress messages below threshold.
-→ See `TASK-04-log-level.md`
-
-### MEDIUM — `SessionManager.cs`
-
-**Gap 5 — No holiday awareness**
-`IsRegularTradingHours()` checks session times only. Will attempt to trade on Christmas, Thanksgiving, etc.
-**Fix:** Add static CME holiday set for 2025/2026. Return `false` on those dates.
-→ See `TASK-05-session-holidays.md`
-
----
-
-## Architecture (Read Before Touching Anything)
-
-```
-SimpleORBStrategy.OnBar()
-    ↓ returns StrategyIntent
-NT8StrategyBase.OnBarUpdate()
-    ↓ [TASK-01: kill switch check here, first]
-    ↓ calls ProcessStrategyIntent()
-    ↓ calls _riskManager.ValidateOrder()
-    ↓ calls _positionSizer.CalculateSize()
-    ↓ calls SubmitOrderToNT8()
-    ↓ [TASK-02: circuit breaker gate here]
-    ↓ calls EnterLong/EnterShort/SetStopLoss/SetProfitTarget (already works)
-NT8 callbacks → OnOrderUpdate / OnExecutionUpdate
-    ↓ [TASK-02: record rejections in circuit breaker here]
-```

-## Technology Constraints
-
-- **C# 5.0 only** — no `$""`, no `?.`, no `=>` on methods/properties, no `nameof()`, no `out var`
-- **.NET Framework 4.8** — not .NET Core/5+/6+
-- **NinjaScript managed orders** — `EnterLong`, `EnterShort`, `SetStopLoss`, `SetProfitTarget`
-- `string.Format()` everywhere, never string interpolation
-- All `Dictionary`, `HashSet` access inside `lock (_lock)` blocks
-- XML doc comments on all public members
-- `try/catch` on all public methods with `LogError` in the catch
+## Compatibility and Safety Baselines

+  - `architecture.md`
+  - `current_status.md`
+  - `roadmap.md`
+  - `active_work.md`
+- Updated onboarding guidance in `.kilocode/rules/project_context.md` to point new sessions to governance docs first.
+- Reclassified `PROJECT_HANDOVER.md` and `DESIGNED_VS_IMPLEMENTED_GAP_ANALYSIS.md` as historical/contextual references, not primary truth.
+- No code files modified and no file moves performed.
+- Moved `docs/PHASE2_COMPLETION_REPORT.md` to `docs/archive/phase-history/PHASE2_COMPLETION_REPORT.md`.

+Preventive rules to reduce repeat compile failures.
+
+## Core Prevention Rules
+- [ ] Verify NT8 signatures in official docs before adding/changing any `protected override`.
+- [ ] Keep NinjaScript edits within task scope and allowed file boundaries.
+- [ ] Enforce C# 5.0 syntax only; reject C# 6+ constructs.
+- [ ] Keep managed order sequence correct (stop/target before entry on same bar).
+- [ ] Guard `OnBarUpdate` by `BarsInProgress` and bar readiness.
+- [ ] Do not use unsupported attributes/types/enums without confirmation.
+
+## Verification Gates
+- [ ] Run `.\verify-build.bat` after changes.
+- [ ] Run focused tests for changed area.
+- [ ] If NinjaScript touched, compile in NT8 NinjaScript Editor.
+
+## Update Rule
+- [ ] Add a new guardrail entry whenever a compile issue reveals a missing prevention rule.

+## Snapshot (2026-04-05)
+- Program phase: Sprint 2 SIM validation with production-hardening follow-through.
+- Core implementation: complete across major layers with 240+ passing tests.
+- Live focus: execution safety, validation depth, and operational reliability.
+
+## Confirmed Working Areas
+- End-to-end strategy pipeline from signal -> risk -> sizing -> NT8 managed execution.
+- Session handling, portfolio risk controls, and base strategy orchestration.
+- Existing analytics/risk/sizing/OMS foundations remain stable.
+
+## Open Findings Driving Work
+- Runner leg behavior requires explicit validation evidence (`Qty=2` path confirmation).
+- Risk/config consistency checks need tightening in runtime safeguards.
+- Operational controls (CI automation, alerting, and out-of-sample validation) remain pending.
+
+## Operational Reality
+- `dotnet build` success is necessary but not sufficient; NT8 NinjaScript compile remains a separate required validation step.
+- Deployment integrity requires keeping repo and NT8 runtime strategy copies synchronized.

+## Scope
+- This folder (`docs/00-governance/`) is the canonical governance source for project state, priorities, architecture intent, and active execution guidance.
+- Governance is aligned to Sprint 2 (SIM validation) with production hardening gaps tracked and prioritized.
+
+## Current Position (2026-04-05)
+- Core engine is implemented with 240+ passing tests across core components.
+- NT8 execution path is wired and validated in SIM for baseline operation.
+- Remaining work is focused on closing operational hardening gaps and validating runner behavior under production-like conditions.
+
+## Approved Direction
+- Keep execution in managed-order NT8 patterns and C# 5.0 / .NET Framework 4.8 constraints.
+- Complete critical and high-priority hardening tasks before expanding strategy scope.
+- Treat historical handover artifacts as context only; governance decisions flow from this folder.
+
+## Immediate Priorities
+- Confirm runner-leg dual-fill behavior in analyzer/session logs.
+- Close safety and observability items already identified in Sprint 2/3 gap tracking.
+- Maintain strict file-boundary and compile-guardrail discipline for all changes.

+# Patterns and Anti-Patterns
+**Last Updated:** 2026-04-05
+
+Capture recurring implementation patterns that impact compile stability.
+
+## Pattern Entry Template
+- **Context:** where this applies
+- **Good pattern:** concise example/description
+- **Anti-pattern:** concise example/description
+- **Why it matters:** one sentence
+
+## Starter Patterns
+1. **NT8 override signatures**
+   - Good pattern: copy exact signature from official NT8 docs before coding.
+   - Anti-pattern: infer or copy from outdated examples.
+   - Why it matters: prevents `CS0115` and runtime integration drift.
+
+2. **Access modifier on overrides**
+   - Good pattern: use `protected override` for NT8 lifecycle/event methods.
+   - Anti-pattern: `public override` or `private override`.
+   - Why it matters: prevents `CS0507`.
+
+3. **C# 5 compatibility discipline**
+   - Good pattern: `string.Format`, explicit null checks, block-bodied members.
+   - Anti-pattern: string interpolation, null-conditional, expression-bodied members.
+   - Why it matters: prevents avoidable language-version compile failures.
+
+4. **Managed order sequencing**
+   - Good pattern: set stop/target before entry on the same bar.
+   - Anti-pattern: entry first, then stop/target.
+   - Why it matters: avoids silent behavior defects and rejected assumptions.

+# Roadmap
+
+## Sprint 2 (Active): SIM Validation
+- Validate dual-leg execution behavior with log evidence.
+- Complete remaining safety/consistency fixes tied to active gap list.
+- Exit criteria: stable SIM behavior with no unresolved critical gaps.
+
+## Sprint 3: Production Hardening
+- Implement CI build/test automation and operational alerting.
+- Complete lower-priority runtime consistency and observability improvements.
+- Add walk-forward and broader validation coverage beyond in-sample checks.
+
+## Sprint 4: Live Capital Readiness
+- Gate on sustained SIM metrics and drawdown controls.
+- Introduce go-live runbook and operational controls for controlled capital exposure.
+
+## Sprint 5: ML Extension (Deferred)
+- Add inference integration only after sufficient live/sim data and stable production operations.
+
+## Sequencing Rule
+- No feature expansion ahead of unresolved safety and validation gates.
