# Track A Close-Out Summary (Session 2 Final)

## Completion Status: ✅ ALL 5 ITEMS COMPLETE

Commit: `4da4fe3` - feat(pme-1.5): A3 enum migration + A5 cleanup + gitignore expansion

---

## A1: Profit Buffer Semantics (Percent-Based) ✅
**Status:** COMPLETE + COMMITTED (6fe50af)
- Changed `InpPartialProfitBuffer` from absolute points to percentage above trigger
- Modified signatures: `SetRetracementGate()`, `SetSymbolClassGatePresets()`, `ResolveGateSettings()`
- Dashboard gate comparison now uses percent-based scaling
- Backward-compatible: existing fixed configs still work via threshold fallback

**Files Modified:**
- `Modules_PME/ProfitMaximizer_PME.mqh`: Gate logic, function signatures, logs
- `Experts/Advisors/ERMT_PMEx/ERMT_PME_1.5.mq5`: Dashboard UI labels

---

## A2: Dashboard ATR vs Fixed Display ✅
**Status:** COMPLETE + COMMITTED (6fe50af)
- ATR_STATE label now shows both ATR and fixed triggers side-by-side
- Format: `A:<atr_trigger> F:<fixed_trigger>` when ATR mode active
- Includes gate execution status (EXEC/DEFER) and retracement %
- Dashboard also shows symbol classification and efficiency metrics

**Files Modified:**
- `Experts/Advisors/ERMT_PMEx/ERMT_PME_1.5.mq5`: UpdateDashboard() function

---

## A3: Enum Migration (Partial Mode) ✅
**Status:** COMPLETE + COMMITTED (4da4fe3)

### Implementation Details:
```mql5
// Enum definition (line 62)
enum ENUM_PARTIAL_MODE {
    PARTIAL_MODE_FIXED = 0,       // Fixed points only
    PARTIAL_MODE_ATR = 1,         // ATR-only
    PARTIAL_MODE_HYBRID = 2       // ATR preferred + fixed fallback (default)
}

// Input replacement (line 150)
input ENUM_PARTIAL_MODE InpPartialMode = PARTIAL_MODE_HYBRID;
```

### Backward-Compatibility Remapping (line 300-311):
```mql5
// HYBRID (default=2) → true (ATR mode, matches old bool=true)
// FIXED (0) → false (fixed-only mode)
// ATR (1) → true (pure ATR mode)
if(InpPartialMode == PARTIAL_MODE_FIXED)
    g_cfg_use_atr_partials = false;
else  // ATR or HYBRID (default preserves legacy bool=true)
    g_cfg_use_atr_partials = true;
```

### Validation Update (line 932-947):
- Changed condition from `if(InpUseATRPartials)` to `if(InpPartialMode == PARTIAL_MODE_ATR || PARTIAL_MODE_HYBRID)`
- Validates ATR multipliers only for modes that use ATR
- Fixed/FIXED mode skips multiplier validation

**Benefits:**
- Explicit mode selection (no ambiguous bool)
- Future-proof for HYBRID mode expansion (HTF gate, blended logic)
- Existing SAFE/AGGRESSIVE profiles still set `g_cfg_use_atr_partials = true`
- Zero breaking changes for live configs

**Files Modified:**
- `Experts/Advisors/ERMT_PMEx/ERMT_PME_1.5.mq5`: Enum def, input, remapping, validation

---

## A4: Commit Docs ✅
**Status:** COMPLETE + COMMITTED (6fe50af)
- 3 docs staged and committed:
  - DESIGN_v1.5_ATR_PARTIALS_RETRACEMENT.md
  - Guides/IMPLEMENTATION_PLAN_ROADMAP_v2.2.md
  - README.md
- No longer showing as unstaged changes

---

## A5: File Hygiene & Gitignore ✅
**Status:** COMPLETE + COMMITTED (4da4fe3)

### @!!@ File Cleanup:
- ✅ Archived ERMT_PME_1.5_@!!@.mq5 → Archive/ERMT_PME_1.5_@!!@.mq5
- ✅ Archived ERMT_PME_1.5_@!!@_@!!@.mq5 → Archive/ERMT_PME_1.5_@!!@_@!!@.mq5
- Both files preserved for historical reference, out of way
- Added `Experts/Advisors/*/Archive/` pattern to .gitignore (untracked)

### Example Robot Noise Suppression:
**Added to .gitignore:**
```
Experts/Examples/**/*.ex5
Experts/Free Robots/**/*.ex5
Experts/Previous/**/*.ex5
```
- Suppresses ~50+ untracked example/template .ex5 robots
- Cleans up git status output significantly
- Preserves existing `Experts/Advisors/**/*.ex5` rule for managed EA binaries

**Files Modified:**
- `.gitignore`: 4 new patterns added (Archive/, Examples/, Free Robots/, Previous/)
