## Reserve Cache API

### Package: `pkg/cache`

The reserve cache provides intelligent caching of pool reserve data with TTL-based expiration and event-driven invalidation.

### Types

#### `ReserveData`

```go
type ReserveData struct {
    Reserve0     *big.Int      // Token0 reserve amount
    Reserve1     *big.Int      // Token1 reserve amount
    Liquidity    *big.Int      // Pool liquidity (V3 only)
    SqrtPriceX96 *big.Int      // Square root price X96 (V3 only)
    Tick         int           // Current tick (V3 only)
    LastUpdated  time.Time     // Cache timestamp
    IsV3         bool          // True if Uniswap V3 pool
}
```

#### `ReserveCache`

```go
type ReserveCache struct {
    // Internal fields (private)
}
```

### Constructor

#### `NewReserveCache`

```go
func NewReserveCache(
    client *ethclient.Client,
    logger *logger.Logger,
    ttl time.Duration,
) *ReserveCache
```

**Parameters:**
- `client` - Ethereum RPC client for fetching reserve data
- `logger` - Logger instance for debug/error messages
- `ttl` - Time-to-live duration (recommended: 45 seconds)

**Returns:** Initialized `*ReserveCache` with background cleanup running

**Example:**
```go
import (
    "time"
    "github.com/fraktal/mev-beta/pkg/cache"
)

reserveCache := cache.NewReserveCache(ethClient, logger, 45*time.Second)
```

---

### Methods

#### `GetOrFetch`

Retrieves cached reserve data or fetches from RPC if cache miss/expired.

```go
func (rc *ReserveCache) GetOrFetch(
    ctx context.Context,
    poolAddress common.Address,
    isV3 bool,
) (*ReserveData, error)
```

**Parameters:**
- `ctx` - Context for RPC calls (with timeout recommended)
- `poolAddress` - Pool contract address
- `isV3` - `true` for Uniswap V3, `false` for V2

**Returns:**
- `*ReserveData` - Pool reserve information
- `error` - RPC or decoding errors

**Example:**
```go
ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
defer cancel()

reserveData, err := reserveCache.GetOrFetch(ctx, poolAddr, true)
if err != nil {
    logger.Error("Failed to fetch reserves", "pool", poolAddr.Hex(), "error", err)
    return err
}

logger.Info("Reserve data",
    "reserve0", reserveData.Reserve0.String(),
    "reserve1", reserveData.Reserve1.String(),
    "tick", reserveData.Tick,
)
```

---

#### `Invalidate`

Manually invalidates cached data for a specific pool.

```go
func (rc *ReserveCache) Invalidate(poolAddress common.Address)
```

**Parameters:**
- `poolAddress` - Pool to invalidate

**Use Cases:**
- Pool state changed (Swap, AddLiquidity, RemoveLiquidity events)
- Manual cache clearing
- Testing scenarios

**Example:**
```go
// Event-driven invalidation
if event.Type == events.Swap {
    reserveCache.Invalidate(event.PoolAddress)
    logger.Debug("Cache invalidated due to Swap event", "pool", event.PoolAddress.Hex())
}
```

---

#### `InvalidateMultiple`

Invalidates multiple pools in a single call.

```go
func (rc *ReserveCache) InvalidateMultiple(poolAddresses []common.Address)
```

**Parameters:**
- `poolAddresses` - Slice of pool addresses to invalidate

**Example:**
```go
affectedPools := []common.Address{pool1, pool2, pool3}
reserveCache.InvalidateMultiple(affectedPools)
```

---

#### `GetMetrics`

Returns cache performance metrics.

```go
func (rc *ReserveCache) GetMetrics() (hits, misses uint64, hitRate float64, size int)
```

**Returns:**
- `hits` - Total cache hits
- `misses` - Total cache misses
- `hitRate` - Hit rate as decimal (0.0-1.0)
- `size` - Current number of cached entries

**Example:**
```go
hits, misses, hitRate, size := reserveCache.GetMetrics()
logger.Info("Cache metrics",
    "hits", hits,
    "misses", misses,
    "hitRate", fmt.Sprintf("%.2f%%", hitRate*100),
    "entries", size,
)

// Alert if hit rate drops below threshold
if hitRate < 0.60 {
    logger.Warn("Low cache hit rate", "hitRate", hitRate)
}
```

---

#### `Clear`

Clears all cached entries.

```go
func (rc *ReserveCache) Clear()
```

**Use Cases:**
- Testing cleanup
- Manual cache reset
- Emergency cache invalidation

**Example:**
```go
// Clear cache during testing
reserveCache.Clear()
```

---

#### `Stop`

Stops the background cleanup goroutine.

```go
func (rc *ReserveCache) Stop()
```

**Important:** Call during graceful shutdown to prevent goroutine leaks.

**Example:**
```go
// In main application shutdown
defer reserveCache.Stop()
```

---

### Helper Functions

#### `CalculateV3ReservesFromState`

Calculates approximate V3 reserves from liquidity and price (fallback when RPC fails).

```go
func CalculateV3ReservesFromState(
    liquidity *big.Int,
    sqrtPriceX96 *big.Int,
) (reserve0, reserve1 *big.Int)
```

**Parameters:**
- `liquidity` - Pool liquidity value
- `sqrtPriceX96` - Square root price in X96 format

**Returns:**
- `reserve0` - Calculated token0 reserve
- `reserve1` - Calculated token1 reserve

**Example:**
```go
reserve0, reserve1 := cache.CalculateV3ReservesFromState(
    poolData.Liquidity.ToBig(),
    poolData.SqrtPriceX96.ToBig(),
)
```

---

## MultiHopScanner Updates

### Package: `pkg/arbitrage`

### Constructor Changes

#### `NewMultiHopScanner` (Updated Signature)

```go
func NewMultiHopScanner(
    logger *logger.Logger,
    client *ethclient.Client,  // NEW PARAMETER
    marketMgr interface{},
) *MultiHopScanner
```

**New Parameter:**
- `client` - Ethereum RPC client for reserve cache initialization

**Example:**
```go
import (
    "github.com/fraktal/mev-beta/pkg/arbitrage"
    "github.com/ethereum/go-ethereum/ethclient"
)

ethClient, err := ethclient.Dial(rpcEndpoint)
if err != nil {
    log.Fatal(err)
}

scanner := arbitrage.NewMultiHopScanner(logger, ethClient, marketManager)
```

---

### Updated Fields

```go
type MultiHopScanner struct {
    logger       *logger.Logger
    client       *ethclient.Client         // NEW: RPC client
    reserveCache *cache.ReserveCache       // NEW: Reserve cache
    // ... existing fields
}
```

---

### Reserve Fetching

The scanner now automatically uses the reserve cache when calculating profits. No changes needed in existing code that calls `CalculateProfit()` or similar methods.

**Internal Change (developers don't need to modify):**
```go
// OLD (in multihop.go):
k := new(big.Float).SetInt(pool.Liquidity.ToBig())
k.Mul(k, k)
reserve0Float := new(big.Float).Sqrt(new(big.Float).Mul(k, priceInv))

// NEW (automatic with cache):
reserveData, err := mhs.reserveCache.GetOrFetch(ctx, pool.Address, isV3)
reserve0 = reserveData.Reserve0
reserve1 = reserveData.Reserve1
```

---

## Scanner Integration

### Package: `pkg/scanner`

### Constructor Changes

#### `NewScanner` (Updated Signature)

```go
func NewScanner(
    cfg *config.BotConfig,
    logger *logger.Logger,
    contractExecutor *contracts.ContractExecutor,
    db *database.Database,
    reserveCache *cache.ReserveCache,  // NEW PARAMETER
) *Scanner
```

**New Parameter:**
- `reserveCache` - Optional reserve cache instance (can be `nil`)

**Backward Compatible:** Pass `nil` if not using cache.

**Example:**
```go
// With cache
reserveCache := cache.NewReserveCache(client, logger, 45*time.Second)
scanner := scanner.NewScanner(cfg, logger, executor, db, reserveCache)

// Without cache (backward compatible)
scanner := scanner.NewScanner(cfg, logger, executor, db, nil)
```

---

#### `NewMarketScanner` (Variadic Wrapper)

```go
func NewMarketScanner(
    cfg *config.BotConfig,
    log *logger.Logger,
    extras ...interface{},
) *Scanner
```

**Variadic Parameters:**
- `extras[0]` - `*contracts.ContractExecutor`
- `extras[1]` - `*database.Database`
- `extras[2]` - `*cache.ReserveCache` (NEW, optional)

**Example:**
```go
// With all parameters
scanner := scanner.NewMarketScanner(cfg, logger, executor, db, reserveCache)

// Without cache (backward compatible)
scanner := scanner.NewMarketScanner(cfg, logger, executor, db)

// Minimal (backward compatible)
scanner := scanner.NewMarketScanner(cfg, logger)
```

---

### Event-Driven Cache Invalidation

The scanner automatically invalidates the cache when pool state changes. This happens internally in the event processing pipeline.

**Internal Implementation (in `concurrent.go`):**
```go
// EVENT-DRIVEN CACHE INVALIDATION
if w.scanner.reserveCache != nil {
    switch event.Type {
    case events.Swap, events.AddLiquidity, events.RemoveLiquidity:
        w.scanner.reserveCache.Invalidate(event.PoolAddress)
    }
}
```

**Developers don't need to call `Invalidate()` manually** - it's automatic!

---

## SwapAnalyzer Enhancements

### Package: `pkg/scanner/swap`

### New Method: `calculatePriceAfterSwap`

Calculates the price after a swap using Uniswap V3's concentrated liquidity formula.

```go
func (s *SwapAnalyzer) calculatePriceAfterSwap(
    poolData *market.CachedData,
    amount0 *big.Int,
    amount1 *big.Int,
    priceBefore *big.Float,
) (*big.Float, int)
```

**Parameters:**
- `poolData` - Pool state data with liquidity
- `amount0` - Swap amount for token0 (negative if out)
- `amount1` - Swap amount for token1 (negative if out)
- `priceBefore` - Price before the swap

**Returns:**
- `*big.Float` - Price after the swap
- `int` - Tick after the swap

**Formula:**
```
Uniswap V3: Δ√P = Δx / L

Where:
  - Δ√P = Change in square root of price
  - Δx = Amount of token swapped
  - L = Pool liquidity

Token0 in (Token1 out): sqrtPriceAfter = sqrtPriceBefore - (amount0 / L)
Token1 in (Token0 out): sqrtPriceAfter = sqrtPriceBefore + (amount1 / L)
```

**Example:**
```go
priceAfter, tickAfter := swapAnalyzer.calculatePriceAfterSwap(
    poolData,
    event.Amount0,
    event.Amount1,
    priceBefore,
)

logger.Info("Swap price movement",
    "priceBefore", priceBefore.String(),
    "priceAfter", priceAfter.String(),
    "tickBefore", poolData.Tick,
    "tickAfter", tickAfter,
)
```

---

### Updated Price Impact Calculation

Price impact is now calculated based on liquidity depth, not swap amount ratios.

**New Formula:**
```go
// Determine swap direction
var amountIn *big.Int
if amount0.Sign() > 0 && amount1.Sign() < 0 {
    amountIn = abs(amount0) // Token0 in, Token1 out
} else if amount0.Sign() < 0 && amount1.Sign() > 0 {
    amountIn = abs(amount1) // Token1 in, Token0 out
}

// Calculate impact as percentage of liquidity
priceImpact = amountIn / (liquidity / 2)
```

**Developers don't need to change code** - this is internal to `SwapAnalyzer.Process()`.

---

## Migration Guide

### For Existing Code

#### If You're Using `MultiHopScanner`:

**Old Code:**

import (
    "context"
    "math/big"
    "testing"
    "time"

    "github.com/ethereum/go-ethereum/common"
    "github.com/fraktal/mev-beta/pkg/cache"

    // Test cache miss (first fetch)
    ctx := context.Background()
    data1, err := reserveCache.GetOrFetch(ctx, poolAddr, true)
    assert.NoError(t, err)
    assert.NotNil(t, data1)

    // Verify metrics

## Testing Utilities

### Mock Reserve Cache

```go
package testutils

import (
    "context"
    "math/big"

    "github.com/ethereum/go-ethereum/common"
    "github.com/fraktal/mev-beta/pkg/cache"
)

type MockReserveCache struct {
    data map[common.Address]*cache.ReserveData
}

func NewMockReserveCache() *MockReserveCache {
    return &MockReserveCache{
        data: make(map[common.Address]*cache.ReserveData),
    }
}

func (m *MockReserveCache) GetOrFetch(
    ctx context.Context,
    poolAddress common.Address,
    isV3 bool,
) (*cache.ReserveData, error) {
    if data, ok := m.data[poolAddress]; ok {
        return data, nil
    }

    // Return mock data
    return &cache.ReserveData{
        Reserve0:     big.NewInt(1000000000000000000), // 1 ETH
        Reserve1:     big.NewInt(2000000000000),        // 2000 USDC
        Liquidity:    big.NewInt(5000000000000000000),
        SqrtPriceX96: big.NewInt(1234567890),
        Tick:         100,
        IsV3:         isV3,
    }, nil
}

func (m *MockReserveCache) Invalidate(poolAddress common.Address) {
    delete(m.data, poolAddress)
}

func (m *MockReserveCache) SetMockData(poolAddress common.Address, data *cache.ReserveData) {
    m.data[poolAddress] = data
}
```

**Usage in Tests:**
```go
func TestArbitrageWithMockCache(t *testing.T) {
    mockCache := testutils.NewMockReserveCache()

    // Set custom reserve data
    poolAddr := common.HexToAddress("0x123...")
    mockCache.SetMockData(poolAddr, &cache.ReserveData{
        Reserve0: big.NewInt(10000000000000000000), // 10 ETH
        Reserve1: big.NewInt(20000000000000),        // 20000 USDC
        IsV3:     true,
    })

    // Use in scanner
    scanner := scanner.NewScanner(cfg, logger, nil, nil, mockCache)
    // ... run tests
}
```

## Performance Monitoring

### Recommended Metrics to Track

```go
package monitoring

import (
    "fmt"
    "time"

    "github.com/fraktal/mev-beta/pkg/cache"
)

type CacheMonitor struct {
    cache     *cache.ReserveCache
    logger    Logger
    alertChan chan CacheAlert
}

type CacheAlert struct {
    Level   string
    Message string
    HitRate float64
}

func (m *CacheMonitor) StartMonitoring(interval time.Duration) {
    ticker := time.NewTicker(interval)
    go func() {
        for range ticker.C {
            m.checkMetrics()
        }
    }()
}

func (m *CacheMonitor) checkMetrics() {
    hits, misses, hitRate, size := m.cache.GetMetrics()

    // Log metrics
    m.logger.Info("Cache performance",
        "hits", hits,
        "misses", misses,
        "hitRate", fmt.Sprintf("%.2f%%", hitRate*100),
        "entries", size,
    )

    // Alert on low hit rate
    if hitRate < 0.60 && (hits+misses) > 100 {
        m.alertChan <- CacheAlert{
            Level:   "WARNING",
            Message: "Cache hit rate below 60%",
            HitRate: hitRate,
        }
    }

    // Alert on excessive cache size
    if size > 500 {
        m.alertChan <- CacheAlert{
            Level:   "WARNING",
            Message: fmt.Sprintf("Cache size exceeds threshold: %d entries", size),
            HitRate: hitRate,
        }
    }
}
```

---

## Troubleshooting

### Common Issues and Solutions

#### 1. Low Cache Hit Rate (<60%)

**Symptoms:**
- `hitRate` metric consistently below 0.60
- High RPC call volume

**Possible Causes:**
- TTL too short (increase from 45s to 60s)
- Too many cache invalidations (check event frequency)
- High pool diversity (many unique pools queried)

**Solutions:**
```go
// Increase TTL
reserveCache := cache.NewReserveCache(client, logger, 60*time.Second)

// Check invalidation frequency
invalidationCount := 0
// ... in event handler
if event.Type == events.Swap {
    invalidationCount++
    if invalidationCount > 100 {
        logger.Warn("High invalidation frequency", "count", invalidationCount)
    }
}
```

---

#### 2. RPC Timeouts

**Symptoms:**
- Errors: "context deadline exceeded"
- Slow cache fetches

**Solutions:**
```go
// Increase RPC timeout
ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
defer cancel()

reserveData, err := reserveCache.GetOrFetch(ctx, poolAddr, isV3)
if err != nil {
    logger.Error("RPC timeout", "pool", poolAddr.Hex(), "error", err)
    // Use fallback calculation
}
```

---

#### 3. Memory Usage Growth

**Symptoms:**
- Cache size growing unbounded
- Memory leaks

**Solutions:**
```go
// Monitor cache size
hits, misses, hitRate, size := reserveCache.GetMetrics()
if size > 1000 {
    logger.Warn("Cache size excessive, clearing old entries", "size", size)
    // Cache auto-cleanup should handle this, but can manually clear if needed
}

// Reduce TTL to increase cleanup frequency
reserveCache := cache.NewReserveCache(client, logger, 30*time.Second)
```
