# 2026-02-09 - Lemontropia Suite Development

## Session Summary
Completed full integration between Loadout Manager and Hunting Sessions. Users can now configure complete loadouts and use them to track costs during actual hunting.

## Bug Fixes

### Plate Selector Crash
- **Issue**: `AttributeError: 'NexusPlate' object has no attribute 'protection_acid'`
- **Root Cause**: `NexusPlate` dataclass was missing `protection_acid` and `protection_electric` fields
- **Fix**: Added missing fields to dataclass and updated `from_api()` method
- **Commit**: `b8fc0a8`

### Attachment Selector Error  
- **Issue**: "object has no attribute get_all_attachments"
- **Fix**: Updated `AttachmentLoaderThread` to use separate endpoints:
  - `/weaponamplifiers` for amplifiers
  - `/weaponvisionattachments` for scopes/sights
  - `/absorbers` for absorbers
- **Commit**: `a5f286a`

## New Features Implemented

### 1. Armor Set Selection
- **File**: `ui/armor_set_selector.py`
- **API**: Added `NexusArmorSet` dataclass and `get_all_armor_sets()` method
- **Endpoint**: `/armorsets`
- **Features**:
  - Browse full armor sets (e.g., "Ghost Set", "Shogun Set")
  - Shows pieces in set, total protection, set bonuses
  - Search by set name or piece name
- **Commit**: `6bcd0ca`, `1e115db`

### 2. Mindforce Implants
- **File**: `ui/mindforce_selector.py`
- **API**: Added `NexusMindforceImplant` dataclass and `get_all_mindforce_implants()` method
- **Endpoint**: `/mindforceimplants`
- **Features**:
  - Supports healing, damage, and utility chip types
  - Shows decay cost per use
  - Color-coded by type
- **Commit**: `6bcd0ca`, `1e115db`

### 3. Tier-Based Enhancer System
- **Change**: Updated `LoadoutConfig.enhancers` from `List[NexusEnhancer]` to `Dict[int, NexusEnhancer]`
- **Structure**: `{tier_number: enhancer}` where tier 1-10
- **Logic**: Each tier can hold exactly 1 enhancer type
- **Decay**: All equipped enhancers contribute to total decay per shot
- **Commit**: `b58af87`

## Loadout-Session Integration (NEW)

### Database Schema Updates
- **New table**: `loadouts` - stores complete gear configurations
  - Weapon with attachments (amp, scope, absorber)
  - Armor with plates (JSON)
  - Healing tool
  - Mindforce implant
  - Accessories (rings, pet, clothing)
  - Enhancers (JSON with tier mapping)
  - Pre-calculated per-action costs
- **Updated table**: `hunting_sessions` - added `loadout_id` foreign key
- **File**: `core/schema.sql`

### Core Modules

#### LoadoutDatabase (`core/loadout_db.py`)
- CRUD operations for loadouts
- `save_loadout()` - Save complete configuration
- `get_loadout()` - Retrieve by name
- `list_loadouts()` - List all saved
- `set_active_loadout()` - Mark as default
- `link_loadout_to_session()` - Associate with hunting session
- `update_session_costs()` - Calculate costs based on loadout

#### SessionCostTracker (`core/session_cost_tracker.py`)
- Real-time cost tracking during hunting
- Tracks per-action costs:
  - Cost per shot (weapon + ammo + enhancers + amp)
  - Cost per hit (armor decay)
  - Cost per heal (FAP/chip decay)
  - Mindforce decay (if using implants)
- Callback system for live HUD updates
- Automatic database persistence

### UI Components

#### LoadoutSelectionDialog (`ui/loadout_selection_dialog.py`)
- Shown when starting a hunting session
- Lists all saved loadouts with preview
- Shows per-action costs for comparison
- Option to skip (no cost tracking)

#### HUDOverlay Updates
- New display row for loadout metrics:
  - $/shot - Cost per weapon shot
  - $/hit - Cost per armor hit taken
  - $/heal - Cost per heal used
  - Hits - Number of hits taken
  - Heals - Number of heals used
- `set_cost_tracker()` method for live updates
- Mindforce cost tracking support

### Usage Flow
```
1. User creates loadout in Loadout Manager
   → Saved to database with per-action costs calculated

2. User starts hunting session
   → LoadoutSelectionDialog appears
   → User selects loadout (or skips)
   → Session linked to loadout_id

3. During hunting
   → LogWatcher detects events
   → SessionCostTracker calculates costs
   → HUD updates in real-time with loadout-based costs

4. After session
   → Complete cost breakdown stored in database
   → Can compare against loot for true P/L
```

## Data Model Updates

### LoadoutConfig additions:
- `mindforce_implant: Optional[str]` - Selected MF chip
- `mindforce_decay_pec: Decimal` - Decay per use
- `enhancers: Dict[int, NexusEnhancer]` - Tier-based slots

### HUDStats additions:
- `mindforce_cost_total: Decimal` - Accumulated MF costs
- `hits_taken: int` - Number of armor hits
- `heals_used: int` - Number of heals
- `cost_per_shot: Decimal` - From loadout
- `cost_per_hit: Decimal` - From loadout
- `cost_per_heal: Decimal` - From loadout
- `loadout_id: Optional[int]` - Linked loadout

## Git Commits
- `b8fc0a8` - fix(api): fix NexusPlate dataclass
- `a5f286a` - fix(ui): update attachment selector to use new API endpoints
- `6bcd0ca` - feat(api): add armor sets and mindforce implants endpoints
- `1e115db` - feat(ui): add armor set and mindforce implant selectors
- `b58af87` - feat(loadout): add mindforce implant field and tier-based enhancers
- `af624b2` - feat(core): add loadout-session integration and cost tracking

## Status
✅ Complete loadout-to-session integration ready for testing

### Next Steps:
1. Test loadout selection dialog when starting hunt
2. Verify cost tracking accuracy during live session
3. Add "Loadout" button to main window toolbar
4. Implement actual log parsing to trigger cost updates
5. Add session summary view showing loadout vs actual costs
