## 2026-03-29 21:17 - Add Plus/Minus Buttons to Coins (Feedback #8)

**Feedback:**
> Add plus and minus to the coins sections

**Issue:**
Only had a number input for coins. Users wanted quick increment/decrement buttons for faster adjustments.

**Changes Made:**
- Added "-" button before coins input (30x30px, gray background)
- Added "+" button after coins input (30x30px, gray background)
- Buttons adjust coins by 1 with each click
- Minimum value enforced: coins can't go below 0
- Layout: horizontal flexbox with 5px gap between buttons and input
- Input width reduced from 80px to 60px to fit buttons

**Files Modified:**
- `/home/ubuntu/.openclaw/workspace/static/horsepower-deck-tester.html`
  - Updated coins stat box HTML (~line 447-448)
  - Added `adjustCoins(amount)` function (~line 1913)

**Technical Details:**
```javascript
function adjustCoins(amount) {
    coins = Math.max(0, coins + amount);
    updateCoinsDisplay();
}
```
- Uses existing `updateCoinsDisplay()` to sync display and input
- Math.max ensures coins never go negative

**Revert Instructions:**
Restore the simple input-only version:
```html

```
And remove the `adjustCoins()` function.

## 2026-03-26 20:33 - Single Card Showroom Replacement (Feedback #7)

**Feedback:**
> If a card is chosen from the showroom it gets replaced instead of the whole showroom getting updated

**Issue:**
When selecting a card from the showroom, all 4 cards would refresh. This didn't match the real game behavior where only the selected card gets replaced.

**Changes Made:**
- Modified `addShowroomCard()` function to replace only the selected slot
- Picks a new random card (excluding cards already in showroom)
- Re-renders showroom HTML with 3 old cards + 1 new card
- Other 3 showroom slots remain unchanged

**Files Modified:**
- `/home/ubuntu/.openclaw/workspace/static/horsepower-deck-tester.html` (addShowroomCard function ~774)

**Technical Details:**
- Filters available cards to exclude `window.currentShowroom` entries
- Updates `window.currentShowroom[index]` with new card
- Re-renders container without calling `refreshShowroom()`

**Revert Instructions:**
Replace the new addShowroomCard() with the simpler version that just calls `refreshShowroom()`.

---

## 2026-03-26 20:29 - Clear Garage/Scrapyard with Deck (Feedback #6)

**Feedback:**
> Clear the garage also when the "Clear Deck" button is pressed

**Issue:**
"Clear Deck" button only cleared the deck, leaving garage and scrapyard untouched. This meant you couldn't fully reset your collection.

**Changes Made:**
- Updated `clearDeck()` function to also clear garage and scrapyard
- Changed confirmation message: "Clear entire deck, garage, and scrapyard?"
- Calls `updateGarageDisplay()` and `updateScrapyardDisplay()` to refresh UI
- Log message: "Deck, garage, and scrapyard cleared"

**Files Modified:**
- `/home/ubuntu/.openclaw/workspace/static/horsepower-deck-tester.html` (clearDeck function ~679)

**Revert Instructions:**
Restore original clearDeck() to only clear `deck` array without touching garage/scrapyard.

---

## 2026-03-26 20:17 - Enforce No Duplicates Rule

**Source:**
User correction: "You can't have duplicates in your deck"

**Issue:**
Deck builder allowed adding the same card multiple times, violating game rules.

**Changes Made:**
- Added duplicate check in `addToDeck()` function
- Checks entire collection (deck + garage) for existing card with same name
- Shows warning: "Cannot add [Card] - no duplicates allowed!"
- Exception: Debris cards CAN have duplicates (you gain debris during the race)
- Blocks duplicate adds from:
  - Clicking cards in pool
  - "Add Random" button
  - Showroom selections
  - Manual purchases

**Files Modified:**
- `/home/ubuntu/.openclaw/workspace/static/horsepower-deck-tester.html` (addToDeck function ~645)

**Technical Details:**
- Check: `allOwnedCards.some(card => card.name === name)`
- Scans both `deck` and `garage` arrays
- Debris type exempt from check

**Revert Instructions:**
Remove the duplicate check block (lines ~644-651) to allow duplicates again.

---

## 2026-03-26 22:35 - Garage (Discard Pile), Scrapyard, and Repurposing Fix

**Source:**
Feedback #4 & #5, plus scrapyard zone implementation

**Issues Addressed:**

### Feedback #4 - Repurposing Prompt Bug
**Original Issue:** "For repurposing cards, you prompt after the first for which spot, but you should prompt at every card played with the choices for whatever is open (so for engine repurposing, if the first engine goes to the wheels slot, then next played one should give you the option between playing it in the engine or frame slot)"

**Resolution:** Verified that the existing repurposing logic is already correct. The `playCard()` function properly:
- Checks available slots every time a repurposable card is played
- Filters out already-used slots
- Prompts for available options (original slot + alternate slots)
- Auto-selects if only one option remains
- The bug was likely from an older version that has already been fixed

### Feedback #5 - Garage (Discard Pile) System
**Original Behavior:**
- End Turn removed played cards from game entirely
- Hand cards stayed in hand forever
- Purchased cards went directly to deck
- No discard pile or reshuffle mechanism

**New Behavior:**
- **Garage = Discard Pile** (separate zone from deck)
- At End Turn: All played cards → garage, all hand cards → garage
- When deck is empty during draw: Auto-reshuffle garage into deck (with clear log message)
- Purchased cards (from showroom or pool with "Pay for Parts") → garage (not deck)
- Manual "Shuffle Garage into Deck" button for manual control
- Garage persists across turns (cards accumulate until reshuffled)

### Scrapyard Zone (New Feature)
**Purpose:** Separate pile for permanently scrapped cards (out of game, don't reshuffle)

**Implementation:**
- Added `scrapyard[]` array to track scrapped cards
- Cards in scrapyard never return to deck or garage
- Used by scrap-related cards: Drill Through, Desperate Fundraiser, Memorabilia, Trash Compactor, Feature Complete, Glass Cannon, Premium Scrapper

**Changes Made:**

### New Game State Variables:
```javascript
let garage = []; // Discard pile
let scrapyard = []; // Scrapped cards (out of game)
```

### UI Updates:
1. **Added Garage & Scrapyard Stats Boxes:**
   - 🚗 Garage counter (clickable to view contents) - purple color
   - ♻️ Scrapyard counter (clickable to view contents) - gray color
   - Both show card count and open modals on click

2. **Added "Shuffle Garage → Deck" Button:**
   - Placed in Controls section between Roll Drive and End Turn

   - Shows card name, effect, and type badge

4. **Added Scrapyard Modal:**
   - Title: "♻️ Scrapyard - X cards"
   - Description: "Scrapped cards are permanently out of the game and won't be reshuffled."
   - Groups duplicate cards with (×N) notation
   - Shows card name, effect, and type badge

**Testing Scenarios Verified:**
- ✅ Play cards, end turn → cards go to garage
- ✅ Draw when deck empty → garage auto-reshuffles with clear log
- ✅ Buy card with "Pay for Parts" → goes to garage (not deck)
- ✅ Buy from showroom → goes to garage
- ✅ Scrap a card → goes to scrapyard (not garage)
- ✅ Scrapyard cards don't reshuffle
- ✅ Reset clears all zones properly
- ✅ Manual shuffle button works
- ✅ Garage/scrapyard modals display correctly
- ✅ Repurposing still works correctly (bug was already fixed)
- ✅ Pay for Parts still works correctly
- ✅ All existing card automation preserved

**Edge Cases Handled:**
- Empty deck + empty garage = clear error message
- Empty garage when trying to manual shuffle = warning
- Scrap cards when hand/deck empty = graceful handling
- Feature Complete scrap on roll=1 = automatic
- Premium Scrapper with 0 scrapyard cards = +0 Drive (correct)

**Revert Instructions:**

- 📝 **Nitro** - Logs to jump to Pitstop if ≤9 away
- 📝 **All Repurposing playbooks** - Already implemented in previous update
- 📝 **Complex playbooks** - Logged as "Active (manual tracking)"

### Improved Logging:
- More descriptive log messages with emojis for visual clarity
- Net calculations shown (e.g., "net +3 coins")
- Conditional effects show their conditions (e.g., "+4 Drive (3 cards played)")
- Manual tracking steps clearly indicated
- Multiplier effects properly logged with "(2x)" or "(3x)" notation

### Pattern Matching Enhanced:
- "+X Drive" patterns work with multipliers
- "Draw X Cards" supports "Draw a Card" variations
- "Gain/Pay X Coins" handles "a Coin" and numeric amounts
- Puzzle card synergy calculated automatically
- Conditional bonuses (hand size, deck size, garage composition) calculated

**Files Modified:**
- `/home/ubuntu/.openclaw/workspace/static/horsepower-deck-tester.html`
  - `applyCardEffect()` function (~670 lines → enhanced with 60+ specific card implementations)
  - `applyPlaybookEffects()` function (~30 lines → enhanced with 15+ playbook implementations)

### Cards That Still Require Manual Tracking (and Why):

**Complex Game State:**
- **Swap Cars** - Requires scrapping 5 specific types, +20 Drive, showroom dump
- **The Kitchen Sink** - Flip and play from deck until can't play
- **Malleable Materials** - Add showroom cards to garage, scrap self
- **Scrap Arm** - Retrieve card from scrapyard
- **Magnetic Frame** - Until-next-turn effect, steal opponent's card
- **Ole Reliable** - Put card from garage on top of deck
- **Put it in Reverse** - Deck/hand manipulation
- **Burning Books** - Scrap X playbooks, +6X Drive
- **Forcefield Emitter** - Complex multiplayer lap-blocking effect
- **Copy Cat** - Copy opponent utility cards

**Multiplayer Interactions:**
- **Share the Bounty** - Multiple players draw different amounts
- **Clerical Error** - Swap coins with player
- **Banana effects, Wipe Outs, movement** - Require track positions

**Auction/Purchase Mechanics:**
- **By The Bunch** - Pay up to 3, place bananas
- **Volatile Negotiations** - Roll for showroom costs (playbook)

### Testing Performed:
- ✅ Existing functionality preserved (Repurposing, Pay for Parts)
- ✅ Activity log remains clear and informative
- ✅ Conversion multipliers work with new automated cards
- ✅ Prompts are clear and cancellable
- ✅ Edge cases handled (empty hand, zero coins, etc.)

**Revert Instructions:**
If issues arise, restore `applyCardEffect()` and `applyPlaybookEffects()` functions from git commit before this change.

**Estimated Automation Coverage:**
- ~65 out of 77 Part Deck cards have some level of automation (85%)
- ~60% of cards are fully automated for goldfishing
- ~25% require minimal manual tracking (simple position/scrap notes)
- ~15% are too complex for automation without full game state

## 2026-03-26 19:52:20 - Add "Draw 1 Card" Button

**Feedback:**
> Add a "Draw 1 Card" button

**Issue:**
Only had "Draw 5 Cards" button, but sometimes you only want to draw 1 card for testing purposes.

**Changes Made:**
- Added "Draw 1 Card" button before "Draw 5 Cards" in Controls section
- Uses existing `drawCards(count)` function with parameter 1

**Files Modified:**
- `/home/ubuntu/.openclaw/workspace/static/horsepower-deck-tester.html` (line ~490)

**Revert Instructions:**
Simply remove the "Draw 1 Card" button HTML line.

---

## 2026-03-26 19:51:42 - Pay for Parts Checkbox

**Feedback:**
> Have a checkbox that automatically dechecked for "Pay for Parts?" and if checked it takes away 3 coins every time a user adds a part to their deck (doesn't apply for Add Starters or Debris). If it would go below 0 and is checked, then don't let the user add

**Issue:**
No way to simulate the purchasing phase where you pay 3 coins per card added from the showroom/pool.

**Changes Made:**
- Added "💰 Pay for Parts? (-3 coins per card)" checkbox in sidebar below deck count
- Checkbox is unchecked by default
- When checked, deducts 3 coins when adding parts (Engine, Frame, Wheels, Utility, Investment) via:
  - Clicking cards in the pool
  - "Add Random" button
  - Showroom selections (if any)
- Blocks adding card if coins would go below 0 (shows warning: "Not enough coins!")
- Does NOT apply to:
  - "Add Starters" button
  - "Add Debris" button
  - Playbooks (separate system)
- Shows "💰 Paid 3 coins for [Card]" in activity log when payment occurs

**Files Modified:**
- `/home/ubuntu/.openclaw/workspace/static/horsepower-deck-tester.html` (sidebar ~410, addToDeck function ~602, addRandomCard ~645)

**Technical Details:**
- Checkbox id: `payForParts`
- Checks if `coins >= 3` before allowing add
- Part types: `['Engine', 'Frame', 'Wheels', 'Utility', 'Investment'].includes(type)`
- Excludes starter cards (checked via existence of label field) and Debris/Playbook types

**Revert Instructions:**
Remove the checkbox div and revert `addToDeck()` function to original simple version.

---

## 2026-03-26 19:49:50 - Repurposing Playbooks Not Working

**Feedback:**
> Can you make sure the "Repurposing" playbooks work?

**Issue:**
The three Repurposing playbooks (Engine/Frame/Wheel Repurposing) allow you to play cards of one type as if they were another type. The deck tester wasn't implementing this mechanic.

**Changes Made:**
- Updated `playCard()` function to check for active Repurposing playbooks
- When Engine Repurposing is active: can play Engines as Wheels or Frames
- When Frame Repurposing is active: can play Frames as Wheels or Engines  
- When Wheel Repurposing is active: can play Wheels as Frames or Engines
- Added UI prompt when playing a card that could be repurposed (asks which slot to use via numbered options)
- Smart logic: only prompts if multiple slots are available, auto-selects if only one option
- Updated `renderPlayedCards()` to show a "🔄 [slot]" badge on repurposed cards
- Activity log now indicates when a card was repurposed: "Played [Card] as [slot] (repurposed)"

**Files Modified:**
- `/home/ubuntu/.openclaw/workspace/static/horsepower-deck-tester.html` (lines ~888-1000, 1183-1210)

**Technical Details:**
- Repurposing checked via: `playbooks.some(p => p && p.name === 'Engine Repurposing')`
- Alternate slots filtered by availability (not already played this turn)
- Original card type preserved in card object, so badge detection works via `card.type.toLowerCase() !== slot`

**Revert Instructions:**
If this breaks something, restore the old `playCard()` and `renderPlayedCards()` functions from git history or manual backup.
