Decompose handle-event.go into DDD domain services (v0.36.15)

Major refactoring of event handling into clean, testable domain services:

- Add pkg/event/validation: JSON hex validation, signature verification,
  timestamp bounds, NIP-70 protected tag validation
- Add pkg/event/authorization: Policy and ACL authorization decisions,
  auth challenge handling, access level determination
- Add pkg/event/routing: Event router registry with ephemeral and delete
  handlers, kind-based dispatch
- Add pkg/event/processing: Event persistence, delivery to subscribers,
  and post-save hooks (ACL reconfig, sync, relay groups)
- Reduce handle-event.go from 783 to 296 lines (62% reduction)
- Add comprehensive unit tests for all new domain services
- Refactor database tests to use shared TestMain setup
- Fix blossom URL test expectations (missing "/" separator)
- Add go-memory-optimization skill and analysis documentation
- Update DDD_ANALYSIS.md to reflect completed decomposition

+name: go-memory-optimization
+description: This skill should be used when optimizing Go code for memory efficiency, reducing GC pressure, implementing object pooling, analyzing escape behavior, choosing between fixed-size arrays and slices, designing worker pools, or profiling memory allocations. Provides comprehensive knowledge of Go's memory model, stack vs heap allocation, sync.Pool patterns, goroutine reuse, and GC tuning.

+
+# Go Memory Optimization
+
+## Overview
+
+This skill provides guidance on optimizing Go programs for memory efficiency and reduced garbage collection overhead. Topics include stack allocation semantics, fixed-size types, escape analysis, object pooling, goroutine management, and GC tuning.
+
+## Core Principles
+
+### The Allocation Hierarchy
+
+Prefer allocations in this order (fastest to slowest):
+
+1. **Stack allocation** - Zero GC cost, automatic cleanup on function return
+2. **Pooled objects** - Amortized allocation cost via sync.Pool
+3. **Pre-allocated buffers** - Single allocation, reused across operations
+4. **Heap allocation** - GC-managed, use when lifetime exceeds function scope
+
+### When Optimization Matters
+
+Focus memory optimization efforts on:
+- Hot paths executed thousands/millions of times per second
+- Large objects (>32KB) that stress the GC
+- Long-running services where GC pauses affect latency
+- Memory-constrained environments
+
+Avoid premature optimization. Profile first with `go tool pprof` to identify actual bottlenecks.
+
+## Fixed-Size Types vs Slices
+
+### Stack Allocation with Arrays
+
+Arrays with known compile-time size can be stack-allocated, avoiding heap entirely:
+
+```go
+// HEAP: slice header + backing array escape to heap
+func processSlice() []byte {
+    data := make([]byte, 32)
+    // ... use data
+    return data  // escapes
+}
+
+// STACK: fixed array stays on stack if doesn't escape
+func processArray() {
+    var data [32]byte  // stack-allocated
+    // ... use data
+}   // automatically cleaned up
+```
+
+### Fixed-Size Binary Types Pattern
+
+Define types with explicit sizes for protocol fields, cryptographic values, and identifiers:
+
+```go
+// Binary types enforce length and enable stack allocation
+type EventID [32]byte      // SHA256 hash
+type Pubkey [32]byte       // Schnorr public key
+type Signature [64]byte    // Schnorr signature
+
+// Methods operate on value receivers when size permits
+func (id EventID) Hex() string {
+    return hex.EncodeToString(id[:])
+}
+
+func (id EventID) IsZero() bool {
+    return id == EventID{}  // efficient zero-value comparison
+}
+```
+
+### Size Thresholds
+
+| Size | Recommendation |
+|------|----------------|
+| ≤64 bytes | Pass by value, stack-friendly |
+| 65-128 bytes | Consider context; value for read-only, pointer for mutation |
+| >128 bytes | Pass by pointer to avoid copy overhead |
+
+### Array to Slice Conversion
+
+Convert fixed arrays to slices only at API boundaries:
+
+```go
+type Hash [32]byte
+
+func (h Hash) Bytes() []byte {
+    return h[:]  // creates slice header, array stays on stack if h does
+}
+
+// Prefer methods that accept arrays directly
+func VerifySignature(pubkey Pubkey, msg []byte, sig Signature) bool {
+    // pubkey and sig are stack-allocated in caller
+}
+```
+
+## Escape Analysis
+
+### Understanding Escape
+
+Variables "escape" to the heap when the compiler cannot prove their lifetime is bounded by the stack frame. Check escape behavior with:
+
+```bash
+go build -gcflags="-m -m" ./...
+```
+
+### Common Escape Causes
+
+```go
+// 1. Returning pointers to local variables
+func escapes() *int {
+    x := 42
+    return &x  // x escapes
+}
+
+// 2. Storing in interface{}
+func escapes(x int) interface{} {
+    return x  // x escapes (boxed)
+}
+
+// 3. Closures capturing by reference
+func escapes() func() int {
+    x := 42
+    return func() int { return x }  // x escapes
+}
+
+// 4. Slice/map with unknown capacity
+func escapes(n int) []byte {
+    return make([]byte, n)  // escapes (size unknown at compile time)
+}
+
+// 5. Sending pointers to channels
+func escapes(ch chan *int) {
+    x := 42
+    ch <- &x  // x escapes
+}
+```
+
+### Preventing Escape
+
+```go
+// 1. Accept pointers, don't return them
+func noEscape(result *[32]byte) {
+    // caller owns memory, function fills it
+    copy(result[:], computeHash())
+}
+
+// 2. Use fixed-size arrays
+func noEscape() {
+    var buf [1024]byte  // known size, stack-allocated
+    process(buf[:])
+}
+
+// 3. Preallocate with known capacity
+func noEscape() {
+    buf := make([]byte, 0, 1024)  // may stay on stack
+    // ... append up to 1024 bytes
+}
+
+// 4. Avoid interface{} on hot paths
+func noEscape(x int) int {
+    return x * 2  // no boxing
+}
+```
+
+## sync.Pool Usage
+
+### Basic Pattern
+
+```go
+var bufferPool = sync.Pool{
+    New: func() interface{} {
+        return make([]byte, 0, 4096)
+    },
+}
+
+func processRequest(data []byte) {
+    buf := bufferPool.Get().([]byte)
+    buf = buf[:0]  // reset length, keep capacity
+    defer bufferPool.Put(buf)
+
+    // use buf...
+}
+```
+
+### Typed Pool Wrapper
+
+```go
+type BufferPool struct {
+    pool sync.Pool
+    size int
+}
+
+func NewBufferPool(size int) *BufferPool {
+    return &BufferPool{
+        pool: sync.Pool{
+            New: func() interface{} {
+                b := make([]byte, size)
+                return &b
+            },
+        },
+        size: size,
+    }
+}
+
+func (p *BufferPool) Get() *[]byte {
+    return p.pool.Get().(*[]byte)
+}
+
+func (p *BufferPool) Put(b *[]byte) {
+    if b == nil || cap(*b) < p.size {
+        return  // don't pool undersized buffers
+    }
+    *b = (*b)[:p.size]  // reset to full size
+    p.pool.Put(b)
+}
+```
+
+### Pool Anti-Patterns
+
+```go
+// BAD: Pool of pointers to small values (overhead exceeds benefit)
+var intPool = sync.Pool{New: func() interface{} { return new(int) }}
+
+// BAD: Not resetting state before Put
+bufPool.Put(buf)  // may contain sensitive data
+
+// BAD: Pooling objects with goroutine-local state
+var connPool = sync.Pool{...}  // connections are stateful
+
+// BAD: Assuming pooled objects persist (GC clears pools)
+obj := pool.Get()
+// ... long delay
+pool.Put(obj)  // obj may have been GC'd during delay
+```
+
+### When to Use sync.Pool
+
+| Use Case | Pool? | Reason |
+|----------|-------|--------|
+| Buffers in HTTP handlers | Yes | High allocation rate, short lifetime |
+| Encoder/decoder state | Yes | Expensive to initialize |
+| Small values (<64 bytes) | No | Pointer overhead exceeds benefit |
+| Long-lived objects | No | Pools are for short-lived reuse |
+| Objects with cleanup needs | No | Pool provides no finalization |
+
+## Goroutine Pooling
+
+### Worker Pool Pattern
+
+```go
+type WorkerPool struct {
+    jobs    chan func()
+    workers int
+    wg      sync.WaitGroup
+}
+
+func NewWorkerPool(workers, queueSize int) *WorkerPool {
+    p := &WorkerPool{
+        jobs:    make(chan func(), queueSize),
+        workers: workers,
+    }
+    p.wg.Add(workers)
+    for i := 0; i < workers; i++ {
+        go p.worker()
+    }
+    return p
+}
+
+func (p *WorkerPool) worker() {
+    defer p.wg.Done()
+    for job := range p.jobs {
+        job()
+    }
+}
+
+func (p *WorkerPool) Submit(job func()) {
+    p.jobs <- job
+}
+
+func (p *WorkerPool) Shutdown() {
+    close(p.jobs)
+    p.wg.Wait()
+}
+```
+
+### Bounded Concurrency with Semaphore
+
+```go
+type Semaphore struct {
+    sem chan struct{}
+}
+
+func NewSemaphore(n int) *Semaphore {
+    return &Semaphore{sem: make(chan struct{}, n)}
+}
+
+func (s *Semaphore) Acquire() { s.sem <- struct{}{} }
+func (s *Semaphore) Release() { <-s.sem }
+
+// Usage
+sem := NewSemaphore(runtime.GOMAXPROCS(0))
+for _, item := range items {
+    sem.Acquire()
+    go func(it Item) {
+        defer sem.Release()
+        process(it)
+    }(item)
+}
+```
+
+### Goroutine Reuse Benefits
+
+| Metric | Spawn per request | Worker pool |
+|--------|-------------------|-------------|
+| Goroutine creation | O(n) | O(workers) |
+| Stack allocation | 2KB × n | 2KB × workers |
+| Scheduler overhead | Higher | Lower |
+| GC pressure | Higher | Lower |
+
+## Reducing GC Pressure
+
+### Allocation Reduction Strategies
+
+```go
+// 1. Reuse buffers across iterations
+buf := make([]byte, 0, 4096)
+for _, item := range items {
+    buf = buf[:0]  // reset without reallocation
+    buf = processItem(buf, item)
+}
+
+// 2. Preallocate slices with known length
+result := make([]Item, 0, len(input))  // avoid append reallocations
+for _, in := range input {
+    result = append(result, transform(in))
+}
+
+// 3. Struct embedding instead of pointer fields
+type Event struct {
+    ID        [32]byte    // embedded, not *[32]byte
+    Pubkey    [32]byte    // single allocation for entire struct
+    Signature [64]byte
+    Content   string      // only string data on heap
+}
+
+// 4. String interning for repeated values
+var kindStrings = map[int]string{
+    0: "set_metadata",
+    1: "text_note",
+    // ...
+}
+```
+
+### GC Tuning
+
+```go
+import "runtime/debug"
+
+func init() {
+    // GOGC: target heap growth percentage (default 100)
+    // Lower = more frequent GC, less memory
+    // Higher = less frequent GC, more memory
+    debug.SetGCPercent(50)  // GC when heap grows 50%
+
+    // GOMEMLIMIT: soft memory limit (Go 1.19+)
+    // GC becomes more aggressive as limit approaches
+    debug.SetMemoryLimit(512 << 20)  // 512MB limit
+}
+```
+
+Environment variables:
+
+```bash
+GOGC=50              # More aggressive GC
+GOMEMLIMIT=512MiB    # Soft memory limit
+GODEBUG=gctrace=1    # GC trace output
+```
+
+### Arena Allocation (Go 1.20+, experimental)
+
+```go
+//go:build goexperiment.arenas
+
+import "arena"
+
+func processLargeDataset(data []byte) Result {
+    a := arena.NewArena()
+    defer a.Free()  // bulk free all allocations
+
+    // All allocations from arena are freed together
+    items := arena.MakeSlice[Item](a, 0, 1000)
+    // ... process
+
+    // Copy result out before Free
+    return copyResult(result)
+}
+```
+
+## Memory Profiling
+
+### Heap Profile
+
+```go
+import "runtime/pprof"
+
+func captureHeapProfile() {
+    f, _ := os.Create("heap.prof")
+    defer f.Close()
+    runtime.GC()  // get accurate picture
+    pprof.WriteHeapProfile(f)
+}
+```
+
+```bash
+go tool pprof -http=:8080 heap.prof
+go tool pprof -alloc_space heap.prof  # total allocations
+go tool pprof -inuse_space heap.prof  # current usage
+```
+
+### Allocation Benchmarks
+
+```go
+func BenchmarkAllocation(b *testing.B) {
+    b.ReportAllocs()
+    for i := 0; i < b.N; i++ {
+        result := processData(input)
+        _ = result
+    }
+}
+```
+
+Output interpretation:
+
+```
+BenchmarkAllocation-8  1000000  1234 ns/op  256 B/op  3 allocs/op
+                                            ↑         ↑
+                                   bytes/op   allocations/op
+```
+
+### Live Memory Monitoring
+
+```go
+func printMemStats() {
+    var m runtime.MemStats
+    runtime.ReadMemStats(&m)
+    fmt.Printf("Alloc: %d MB\n", m.Alloc/1024/1024)
+    fmt.Printf("TotalAlloc: %d MB\n", m.TotalAlloc/1024/1024)
+    fmt.Printf("Sys: %d MB\n", m.Sys/1024/1024)
+    fmt.Printf("NumGC: %d\n", m.NumGC)
+    fmt.Printf("GCPause: %v\n", time.Duration(m.PauseNs[(m.NumGC+255)%256]))
+}
+```

+
+## Buffer Pool Implementations
+
+### Tiered Buffer Pool
+
+For workloads with varying buffer sizes:
+
+```go
+type TieredPool struct {
+    small  sync.Pool  // 1KB
+    medium sync.Pool  // 16KB
+    large  sync.Pool  // 256KB
+}
+
+func NewTieredPool() *TieredPool {
+    return &TieredPool{
+        small:  sync.Pool{New: func() interface{} { return make([]byte, 1024) }},
+        medium: sync.Pool{New: func() interface{} { return make([]byte, 16384) }},
+        large:  sync.Pool{New: func() interface{} { return make([]byte, 262144) }},
+    }
+}
+
+func (p *TieredPool) Get(size int) []byte {
+    switch {
+    case size <= 1024:
+        return p.small.Get().([]byte)[:size]
+    case size <= 16384:
+        return p.medium.Get().([]byte)[:size]
+    case size <= 262144:
+        return p.large.Get().([]byte)[:size]
+    default:
+        return make([]byte, size)  // too large for pool
+    }
+}
+
+func (p *TieredPool) Put(b []byte) {
+    switch cap(b) {
+    case 1024:
+        p.small.Put(b[:cap(b)])
+    case 16384:
+        p.medium.Put(b[:cap(b)])
+    case 262144:
+        p.large.Put(b[:cap(b)])
+    }
+    // Non-standard sizes are not pooled
+}
+```
+
+### bytes.Buffer Pool
+
+```go
+var bufferPool = sync.Pool{
+    New: func() interface{} {
+        return new(bytes.Buffer)
+    },
+}
+
+func GetBuffer() *bytes.Buffer {
+    return bufferPool.Get().(*bytes.Buffer)
+}
+
+func PutBuffer(b *bytes.Buffer) {
+    b.Reset()
+    bufferPool.Put(b)
+}
+
+// Usage
+func processData(data []byte) string {
+    buf := GetBuffer()
+    defer PutBuffer(buf)
+
+    buf.WriteString("prefix:")
+    buf.Write(data)
+    buf.WriteString(":suffix")
+
+    return buf.String()  // allocates new string
+}
+```
+
+## Zero-Allocation JSON Encoding
+
+### Pre-allocated Encoder
+
+```go
+type JSONEncoder struct {
+    buf    []byte
+    scratch [64]byte  // for number formatting
+}
+
+func (e *JSONEncoder) Reset() {
+    e.buf = e.buf[:0]
+}
+
+func (e *JSONEncoder) Bytes() []byte {
+    return e.buf
+}
+
+func (e *JSONEncoder) WriteString(s string) {
+    e.buf = append(e.buf, '"')
+    for i := 0; i < len(s); i++ {
+        c := s[i]
+        switch c {
+        case '"':
+            e.buf = append(e.buf, '\\', '"')
+        case '\\':
+            e.buf = append(e.buf, '\\', '\\')
+        case '\n':
+            e.buf = append(e.buf, '\\', 'n')
+        case '\r':
+            e.buf = append(e.buf, '\\', 'r')
+        case '\t':
+            e.buf = append(e.buf, '\\', 't')
+        default:
+            if c < 0x20 {
+                e.buf = append(e.buf, '\\', 'u', '0', '0',
+                    hexDigits[c>>4], hexDigits[c&0xf])
+            } else {
+                e.buf = append(e.buf, c)
+            }
+        }
+    }
+    e.buf = append(e.buf, '"')
+}
+
+func (e *JSONEncoder) WriteInt(n int64) {
+    e.buf = strconv.AppendInt(e.buf, n, 10)
+}
+
+func (e *JSONEncoder) WriteHex(b []byte) {
+    e.buf = append(e.buf, '"')
+    for _, v := range b {
+        e.buf = append(e.buf, hexDigits[v>>4], hexDigits[v&0xf])
+    }
+    e.buf = append(e.buf, '"')
+}
+
+var hexDigits = [16]byte{'0', '1', '2', '3', '4', '5', '6', '7',
+                          '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'}
+```
+
+### Append-Based Encoding
+
+```go
+// AppendJSON appends JSON representation to dst, returning extended slice
+func (ev *Event) AppendJSON(dst []byte) []byte {
+    dst = append(dst, `{"id":"`...)
+    dst = appendHex(dst, ev.ID[:])
+    dst = append(dst, `","pubkey":"`...)
+    dst = appendHex(dst, ev.Pubkey[:])
+    dst = append(dst, `","created_at":`...)
+    dst = strconv.AppendInt(dst, ev.CreatedAt, 10)
+    dst = append(dst, `,"kind":`...)
+    dst = strconv.AppendInt(dst, int64(ev.Kind), 10)
+    dst = append(dst, `,"content":`...)
+    dst = appendJSONString(dst, ev.Content)
+    dst = append(dst, '}')
+    return dst
+}
+
+// Usage with pre-allocated buffer
+func encodeEvents(events []Event) []byte {
+    // Estimate size: ~500 bytes per event
+    buf := make([]byte, 0, len(events)*500)
+    buf = append(buf, '[')
+    for i, ev := range events {
+        if i > 0 {
+            buf = append(buf, ',')
+        }
+        buf = ev.AppendJSON(buf)
+    }
+    buf = append(buf, ']')
+    return buf
+}
+```
+
+## Memory-Efficient String Building
+
+### strings.Builder with Preallocation
+
+```go
+func buildQuery(parts []string) string {
+    // Calculate total length
+    total := len(parts) - 1  // for separators
+    for _, p := range parts {
+        total += len(p)
+    }
+
+    var b strings.Builder
+    b.Grow(total)  // single allocation
+
+    for i, p := range parts {
+        if i > 0 {
+            b.WriteByte(',')
+        }
+        b.WriteString(p)
+    }
+    return b.String()
+}
+```
+
+### Avoiding String Concatenation
+
+```go
+// BAD: O(n^2) allocations
+func buildPath(parts []string) string {
+    result := ""
+    for _, p := range parts {
+        result += "/" + p  // new allocation each iteration
+    }
+    return result
+}
+
+// GOOD: O(n) with single allocation
+func buildPath(parts []string) string {
+    if len(parts) == 0 {
+        return ""
+    }
+    n := len(parts)  // for slashes
+    for _, p := range parts {
+        n += len(p)
+    }

+        b = append(b, '/')
+        b = append(b, p...)

+    return string(b)

+```
+
+### Unsafe String/Byte Conversion
+
+```go
+import "unsafe"
+
+// Zero-allocation string to []byte (read-only!)
+func unsafeBytes(s string) []byte {
+    return unsafe.Slice(unsafe.StringData(s), len(s))
+}
+
+// Zero-allocation []byte to string (b must not be modified!)
+func unsafeString(b []byte) string {
+    return unsafe.String(unsafe.SliceData(b), len(b))
+}
+
+// Use when:
+// 1. Converting string for read-only operations (hashing, comparison)
+// 2. Returning []byte from buffer that won't be modified
+// 3. Performance-critical paths with careful ownership management
+```
+
+## Slice Capacity Management
+
+### Append Growth Patterns
+
+```go
+// Slice growth: 0 -> 1 -> 2 -> 4 -> 8 -> 16 -> 32 -> 64 -> ...
+// After 1024: grows by 25% each time
+
+// BAD: Unknown final size causes multiple reallocations
+func collectItems() []Item {
+    var items []Item
+    for item := range source {
+        items = append(items, item)  // may reallocate multiple times
+    }
+    return items
+}
+
+// GOOD: Preallocate when size is known
+func collectItems(n int) []Item {
+    items := make([]Item, 0, n)
+    for item := range source {
+        items = append(items, item)
+    }
+    return items
+}
+
+// GOOD: Use slice header trick for uncertain sizes
+func collectItems() []Item {
+    items := make([]Item, 0, 32)  // reasonable initial capacity
+    for item := range source {
+        items = append(items, item)
+    }
+    // Trim excess capacity if items will be long-lived
+    return items[:len(items):len(items)]
+}
+```
+
+### Slice Recycling
+
+```go
+// Reuse slice backing array
+func processInBatches(items []Item, batchSize int) {
+    batch := make([]Item, 0, batchSize)
+
+    for i, item := range items {
+        batch = append(batch, item)
+
+        if len(batch) == batchSize || i == len(items)-1 {
+            processBatch(batch)
+            batch = batch[:0]  // reset length, keep capacity
+        }
+    }
+}
+```
+
+### Preventing Slice Memory Leaks
+
+```go
+// BAD: Subslice keeps entire backing array alive
+func getFirst10(data []byte) []byte {
+    return data[:10]  // entire data array stays in memory
+}
+
+// GOOD: Copy to release original array
+func getFirst10(data []byte) []byte {
+    result := make([]byte, 10)
+    copy(result, data[:10])
+    return result
+}
+
+// Alternative: explicit capacity limit
+func getFirst10(data []byte) []byte {
+    return data[:10:10]  // cap=10, can't accidentally grow into original
+}
+```
+
+## Struct Layout Optimization
+
+### Field Ordering for Alignment
+
+```go
+// BAD: 32 bytes due to padding
+type BadLayout struct {
+    a bool      // 1 byte + 7 padding
+    b int64     // 8 bytes
+    c bool      // 1 byte + 7 padding
+    d int64     // 8 bytes
+}
+
+// GOOD: 24 bytes with optimal ordering
+type GoodLayout struct {
+    b int64     // 8 bytes
+    d int64     // 8 bytes
+    a bool      // 1 byte
+    c bool      // 1 byte + 6 padding
+}
+
+// Rule: Order fields from largest to smallest alignment
+```
+
+### Checking Struct Size
+
+```go
+func init() {
+    // Compile-time size assertions
+    var _ [24]byte = [unsafe.Sizeof(GoodLayout{})]byte{}
+
+    // Or runtime check
+    if unsafe.Sizeof(Event{}) > 256 {
+        panic("Event struct too large")
+    }
+}
+```
+
+### Cache-Line Optimization
+
+```go
+const CacheLineSize = 64
+
+// Pad struct to prevent false sharing in concurrent access
+type PaddedCounter struct {
+    value uint64
+    _     [CacheLineSize - 8]byte  // padding
+}
+
+type Counters struct {
+    reads  PaddedCounter
+    writes PaddedCounter
+    // Each counter on separate cache line
+}
+```
+
+## Object Reuse Patterns
+
+### Reset Methods
+
+```go
+type Request struct {
+    Method  string
+    Path    string
+    Headers map[string]string
+    Body    []byte
+}
+
+func (r *Request) Reset() {
+    r.Method = ""
+    r.Path = ""
+    // Reuse map, just clear entries
+    for k := range r.Headers {
+        delete(r.Headers, k)
+    }
+    r.Body = r.Body[:0]
+}
+
+var requestPool = sync.Pool{
+    New: func() interface{} {
+        return &Request{
+            Headers: make(map[string]string, 8),
+            Body:    make([]byte, 0, 1024),
+        }
+    },
+}
+```
+
+### Flyweight Pattern
+
+```go
+// Share immutable parts across many instances
+type Event struct {
+    kind    *Kind   // shared, immutable
+    content string
+}
+
+type Kind struct {
+    ID          int
+    Name        string
+    Description string
+}
+
+var kindRegistry = map[int]*Kind{
+    0: {0, "set_metadata", "User metadata"},
+    1: {1, "text_note", "Text note"},
+    // ... pre-allocated, shared across all events
+}
+
+func NewEvent(kindID int, content string) Event {
+    return Event{
+        kind:    kindRegistry[kindID],  // no allocation
+        content: content,
+    }
+}
+```
+
+## Channel Patterns for Memory Efficiency
+
+### Buffered Channels as Object Pools
+
+```go
+type SimplePool struct {
+    pool chan *Buffer
+}
+
+func NewSimplePool(size int) *SimplePool {
+    p := &SimplePool{pool: make(chan *Buffer, size)}
+    for i := 0; i < size; i++ {
+        p.pool <- NewBuffer()
+    }
+    return p
+}
+
+func (p *SimplePool) Get() *Buffer {
+    select {
+    case b := <-p.pool:
+        return b
+    default:
+        return NewBuffer()  // pool empty, allocate new
+    }
+}
+
+func (p *SimplePool) Put(b *Buffer) {
+    select {
+    case p.pool <- b:
+    default:
+        // pool full, let GC collect
+    }
+}
+```
+
+### Batch Processing Channels
+
+```go
+// Reduce channel overhead by batching
+func batchProcessor(input <-chan Item, batchSize int) <-chan []Item {
+    output := make(chan []Item)
+    go func() {
+        defer close(output)
+        batch := make([]Item, 0, batchSize)
+
+        for item := range input {
+            batch = append(batch, item)
+            if len(batch) == batchSize {
+                output <- batch
+                batch = make([]Item, 0, batchSize)
+            }
+        }
+        if len(batch) > 0 {
+            output <- batch
+        }
+    }()
+    return output
+}
+```
+
+## Advanced Techniques
+
+### Manual Memory Management with mmap
+
+```go
+import "golang.org/x/sys/unix"
+
+// Allocate memory outside Go heap
+func allocateMmap(size int) ([]byte, error) {
+    data, err := unix.Mmap(-1, 0, size,
+        unix.PROT_READ|unix.PROT_WRITE,
+        unix.MAP_ANON|unix.MAP_PRIVATE)
+    return data, err
+}
+
+func freeMmap(data []byte) error {
+    return unix.Munmap(data)
+}
+```
+
+### Inline Arrays in Structs
+
+```go
+// Small-size optimization: inline for small, pointer for large
+type SmallVec struct {
+    len   int
+    small [8]int      // inline storage for ≤8 elements
+    large []int       // heap storage for >8 elements
+}
+
+func (v *SmallVec) Append(x int) {
+    if v.large != nil {
+        v.large = append(v.large, x)
+        v.len++
+        return
+    }
+    if v.len < 8 {
+        v.small[v.len] = x
+        v.len++
+        return
+    }
+    // Spill to heap
+    v.large = make([]int, 9, 16)
+    copy(v.large, v.small[:])
+    v.large[8] = x
+    v.len++
+}
+```
+
+### Bump Allocator
+
+```go
+// Simple arena-style allocator for batch allocations
+type BumpAllocator struct {
+    buf []byte
+    off int
+}
+
+func NewBumpAllocator(size int) *BumpAllocator {
+    return &BumpAllocator{buf: make([]byte, size)}
+}
+
+func (a *BumpAllocator) Alloc(size int) []byte {
+    if a.off+size > len(a.buf) {
+        panic("bump allocator exhausted")
+    }
+    b := a.buf[a.off : a.off+size]
+    a.off += size
+    return b
+}
+
+func (a *BumpAllocator) Reset() {
+    a.off = 0
+}
+
+// Usage: allocate many small objects, reset all at once
+func processBatch(items []Item) {
+    arena := NewBumpAllocator(1 << 20)  // 1MB
+    defer arena.Reset()
+
+    for _, item := range items {
+        buf := arena.Alloc(item.Size())
+        item.Serialize(buf)
+    }
+}
+```

+# ORLY Relay Memory Optimization Analysis
+
+This document analyzes ORLY's current memory optimization patterns against Go best practices for high-performance systems. The analysis covers buffer management, caching strategies, allocation patterns, and identifies optimization opportunities.
+
+## Executive Summary
+
+ORLY implements several sophisticated memory optimization strategies:
+- **Compact event storage** achieving ~87% space savings via serial references
+- **Two-level caching** for serial lookups and query results
+- **ZSTD compression** for query cache with LRU eviction
+- **Atomic operations** for lock-free statistics tracking
+- **Pre-allocation patterns** for slice capacity management
+
+However, several opportunities exist to further reduce GC pressure:
+- Implement `sync.Pool` for frequently allocated buffers
+- Use fixed-size arrays for cryptographic values
+- Pool `bytes.Buffer` instances in hot paths
+- Optimize escape behavior in serialization code
+
+---
+
+## Current Memory Patterns
+
+### 1. Compact Event Storage
+
+**Location**: `pkg/database/compact_event.go`
+
+ORLY's most significant memory optimization is the compact binary format for event storage:
+
+```
+Original event:  32 (ID) + 32 (pubkey) + 32*4 (tags) = 192+ bytes
+Compact format:   5 (pubkey serial) + 5*4 (tag serials) = 25 bytes
+Savings: ~87% compression per event
+```
+
+**Key techniques:**
+- 5-byte serial references replace 32-byte IDs/pubkeys
+- Varint encoding for variable-length integers (CreatedAt, tag counts)
+- Type flags for efficient deserialization
+- Separate `SerialEventId` index for ID reconstruction
+
+**Assessment**: Excellent storage optimization. This dramatically reduces database size and I/O costs.
+
+### 2. Serial Cache System
+
+**Location**: `pkg/database/serial_cache.go`
+
+Two-way lookup cache for serial ↔ ID/pubkey mappings:
+
+```go
+type SerialCache struct {
+    pubkeyBySerial     map[uint64][]byte      // For decoding
+    serialByPubkeyHash map[string]uint64      // For encoding
+    eventIdBySerial    map[uint64][]byte      // For decoding
+    serialByEventIdHash map[string]uint64     // For encoding
+}
+```
+
+**Memory footprint:**
+- Pubkey cache: 100k entries × 32 bytes ≈ 3.2MB
+- Event ID cache: 500k entries × 32 bytes ≈ 16MB
+- Total: ~19-20MB overhead
+
+**Strengths:**
+- Fine-grained `RWMutex` locking per direction/type
+- Configurable cache limits
+- Defensive copying prevents external mutations
+
+**Improvement opportunity:** The eviction strategy (clear 50% when full) is simple but not LRU. Consider ring buffers or generational caching for better hit rates.
+
+### 3. Query Cache with ZSTD Compression
+
+**Location**: `pkg/database/querycache/event_cache.go`
+
+```go
+type EventCache struct {
+    entries   map[string]*EventCacheEntry
+    lruList   *list.List
+    encoder   *zstd.Encoder  // Reused encoder (level 9)
+    decoder   *zstd.Decoder  // Reused decoder
+    maxSize   int64          // Default 512MB compressed
+}
+```
+
+**Strengths:**
+- ZSTD level 9 compression (best ratio)
+- Encoder/decoder reuse avoids repeated initialization
+- LRU eviction with proper size tracking
+- Background cleanup of expired entries
+- Tracks compression ratio with exponential moving average
+
+**Memory pattern:** Stores compressed data in cache, decompresses on-demand. This trades CPU for memory.
+
+### 4. Buffer Allocation Patterns
+
+**Current approach:** Uses `new(bytes.Buffer)` throughout serialization code:
+
+```go
+// pkg/database/save-event.go, compact_event.go, serial_cache.go
+buf := new(bytes.Buffer)
+// ... encode data
+return buf.Bytes()
+```
+
+**Assessment:** Each call allocates a new buffer on the heap. For high-throughput scenarios (thousands of events/second), this creates significant GC pressure.
+
+---
+
+## Optimization Opportunities
+
+### 1. Implement sync.Pool for Buffer Reuse
+
+**Priority: High**
+
+Currently, ORLY creates new `bytes.Buffer` instances for every serialization operation. A buffer pool would amortize allocation costs:
+
+```go
+// Recommended implementation
+var bufferPool = sync.Pool{
+    New: func() interface{} {
+        return bytes.NewBuffer(make([]byte, 0, 4096))
+    },
+}
+
+func getBuffer() *bytes.Buffer {
+    return bufferPool.Get().(*bytes.Buffer)
+}
+
+func putBuffer(buf *bytes.Buffer) {
+    buf.Reset()
+    bufferPool.Put(buf)
+}
+```
+
+**Impact areas:**
+- `pkg/database/compact_event.go` - MarshalCompactEvent, encodeCompactTag
+- `pkg/database/save-event.go` - index key generation
+- `pkg/database/serial_cache.go` - GetEventIdBySerial, StoreEventIdSerial
+
+**Expected benefit:** 50-80% reduction in buffer allocations on hot paths.
+
+### 2. Fixed-Size Array Types for Cryptographic Values
+
+**Priority: Medium**
+
+The external nostr library uses `[]byte` slices for IDs, pubkeys, and signatures. However, these are always fixed sizes:
+
+| Type | Size | Current | Recommended |
+|------|------|---------|-------------|
+| Event ID | 32 bytes | `[]byte` | `[32]byte` |
+| Pubkey | 32 bytes | `[]byte` | `[32]byte` |
+| Signature | 64 bytes | `[]byte` | `[64]byte` |
+
+Internal types like `Uint40` already follow this pattern but use struct wrapping:
+
+```go
+// Current (pkg/database/indexes/types/uint40.go)
+type Uint40 struct{ value uint64 }
+
+// Already efficient - no slice allocation
+```
+
+For cryptographic values, consider wrapper types:
+
+```go
+type EventID [32]byte
+type Pubkey [32]byte
+type Signature [64]byte
+
+func (id EventID) IsZero() bool { return id == EventID{} }
+func (id EventID) Hex() string  { return hex.Enc(id[:]) }
+```
+
+**Benefit:** Stack allocation for local variables, zero-value comparison efficiency.
+
+### 3. Pre-allocated Slice Patterns
+
+**Current usage is good:**
+
+```go
+// pkg/database/save-event.go:51-54
+sers = make(types.Uint40s, 0, len(idxs)*100) // Estimate 100 serials per index
+
+// pkg/database/compact_event.go:283
+ev.Tags = tag.NewSWithCap(int(nTags)) // Pre-allocate tag slice
+```
+
+**Improvement:** Apply consistently to:
+- `Uint40s.Union/Intersection/Difference` methods (currently use `append` without capacity hints)
+- Query result accumulation in `query-events.go`
+
+### 4. Escape Analysis Optimization
+
+**Priority: Medium**
+
+Several patterns cause unnecessary heap escapes. Check with:
+
+```bash
+go build -gcflags="-m -m" ./pkg/database/...
+```
+
+**Common escape causes in codebase:**
+
+```go
+// compact_event.go:224 - Small slice escapes
+buf := make([]byte, 5)  // Could be [5]byte on stack
+
+// compact_event.go:335 - Single-byte slice escapes
+typeBuf := make([]byte, 1)  // Could be var typeBuf [1]byte
+```
+
+**Fix:**
+```go
+func readUint40(r io.Reader) (value uint64, err error) {
+    var buf [5]byte  // Stack-allocated
+    if _, err = io.ReadFull(r, buf[:]); err != nil {
+        return 0, err
+    }
+    // ...
+}
+```
+
+### 5. Atomic Bytes Wrapper Optimization
+
+**Location**: `pkg/utils/atomic/bytes.go`
+
+Current implementation copies on both Load and Store:
+
+```go
+func (x *Bytes) Load() (b []byte) {
+    vb := x.v.Load().([]byte)
+    b = make([]byte, len(vb))  // Allocation on every Load
+    copy(b, vb)
+    return
+}
+```
+
+This is safe but expensive for high-frequency access. Consider:
+- Read-copy-update (RCU) pattern for read-heavy workloads
+- `sync.RWMutex` with direct access for controlled use cases
+
+### 6. Goroutine Management
+
+**Current patterns:**
+- Worker goroutines for message processing (`app/listener.go`)
+- Background cleanup goroutines (`querycache/event_cache.go`)
+- Pinger goroutines per connection (`app/handle-websocket.go`)
+
+**Assessment:** Good use of bounded channels and `sync.WaitGroup` for lifecycle management.
+
+**Improvement:** Consider a worker pool for subscription handlers to limit peak goroutine count:
+
+```go
+type WorkerPool struct {
+    jobs    chan func()
+    workers int
+    wg      sync.WaitGroup
+}
+```
+
+---
+
+## Memory Budget Analysis
+
+### Runtime Memory Breakdown
+
+| Component | Estimated Size | Notes |
+|-----------|---------------|-------|
+| Serial Cache (pubkeys) | 3.2 MB | 100k × 32 bytes |
+| Serial Cache (event IDs) | 16 MB | 500k × 32 bytes |
+| Query Cache | 512 MB | Configurable, compressed |
+| Per-connection state | ~10 KB | Channels, buffers, maps |
+| Badger DB caches | Variable | Controlled by Badger config |
+
+### GC Tuning Recommendations
+
+For a relay handling 1000+ events/second:
+
+```go
+// main.go or init
+import "runtime/debug"
+
+func init() {
+    // More aggressive GC to limit heap growth
+    debug.SetGCPercent(50)  // GC at 50% heap growth (default 100)
+
+    // Set soft memory limit based on available RAM
+    debug.SetMemoryLimit(2 << 30)  // 2GB limit
+}
+```
+
+Or via environment:
+```bash
+GOGC=50 GOMEMLIMIT=2GiB ./orly
+```
+
+---
+
+## Profiling Commands
+
+### Heap Profile
+
+```bash
+# Enable pprof (already supported)
+ORLY_PPROF_HTTP=true ./orly
+
+# Capture heap profile
+go tool pprof http://localhost:6060/debug/pprof/heap
+
+# Analyze allocations
+go tool pprof -alloc_space heap.prof
+go tool pprof -inuse_space heap.prof
+```
+
+### Escape Analysis
+
+```bash
+# Check which variables escape to heap
+go build -gcflags="-m -m" ./pkg/database/... 2>&1 | grep "escapes to heap"
+```
+
+### Allocation Benchmarks
+
+Add to existing benchmarks:
+
+```go
+func BenchmarkCompactMarshal(b *testing.B) {
+    b.ReportAllocs()
+    ev := createTestEvent()
+    resolver := &testResolver{}
+
+    b.ResetTimer()
+    for i := 0; i < b.N; i++ {
+        data, _ := MarshalCompactEvent(ev, resolver)
+        _ = data
+    }
+}
+```
+
+---
+
+## Implementation Priority
+
+1. **High Priority (Immediate Impact)**
+   - Implement `sync.Pool` for `bytes.Buffer` in serialization paths
+   - Replace small `make([]byte, n)` with fixed arrays in decode functions
+
+2. **Medium Priority (Significant Improvement)**
+   - Add pre-allocation hints to set operation methods
+   - Optimize escape behavior in compact event encoding
+   - Consider worker pool for subscription handlers
+
+3. **Low Priority (Refinement)**
+   - LRU-based serial cache eviction
+   - Fixed-size types for cryptographic values (requires nostr library changes)
+   - RCU pattern for atomic bytes in high-frequency paths
+
+---
+
+## Conclusion
+
+ORLY demonstrates thoughtful memory optimization in its storage layer, particularly the compact event format achieving 87% space savings. The dual-cache architecture (serial cache + query cache) balances memory usage with lookup performance.
+
+The primary opportunity for improvement is in the serialization hot path, where buffer pooling could significantly reduce GC pressure. The recommended `sync.Pool` implementation would have immediate benefits for high-throughput deployments without requiring architectural changes.
+
+Secondary improvements around escape analysis and fixed-size types would provide incremental gains and should be prioritized based on profiling data from production workloads.
