Memory Package

The memory package provides persistent storage for routing decisions, provider quirks, and user preferences. This enables switchAILocal to learn from past decisions and improve routing over time.

Overview

The memory system is a core component of the Clawd Patterns Integration that transforms switchAILocal from a stateless proxy into an intelligent, learning gateway. It stores:

  • Routing History: All routing decisions with their outcomes
  • Provider Quirks: Known issues and workarounds for providers
  • User Preferences: Learned preferences per API key
  • Daily Logs: Time-series data for analytics
  • Analytics: Aggregated metrics and performance data

Directory Structure

The memory system creates the following directory structure:

.switchailocal/memory/
├── routing-history.jsonl       # All routing decisions with outcomes
├── provider-quirks.md           # Known issues and workarounds
├── user-preferences/            # Per-API-key preferences
│   ├── sha256-abc123.json
│   └── sha256-def456.json
├── daily/                       # Daily operation logs
│   ├── 2026-02-01.jsonl
│   └── 2026-02-02.jsonl
└── analytics/                   # Aggregated metrics
    ├── provider-stats.json
    └── model-performance.json

Usage

Initializing the Directory Structure
import "github.com/traylinx/switchAILocal/internal/memory"

// Create directory structure manager
ds := memory.NewDirectoryStructure(".switchailocal/memory")

// Initialize the directory structure
if err := ds.Initialize(); err != nil {
    log.Fatalf("Failed to initialize memory structure: %v", err)
}

// Validate the structure
if err := ds.Validate(); err != nil {
    log.Fatalf("Validation failed: %v", err)
}
Getting Paths
// Get path to routing history file
historyPath := ds.GetRoutingHistoryPath()

// Get path to provider quirks file
quirksPath := ds.GetProviderQuirksPath()

// Get path to user preferences directory
prefsDir := ds.GetUserPreferencesDir()

// Get path to specific user's preferences
userPrefsPath := ds.GetUserPreferencePath("sha256:abc123")

// Get path to daily log file
dailyLogPath := ds.GetDailyLogPath("2026-02-02")
Configuration
// Get default configuration
config := memory.DefaultMemoryConfig()

// Customize configuration
config.Enabled = true
config.BaseDir = "/custom/path/memory"
config.RetentionDays = 30
config.MaxLogSizeMB = 50
config.Compression = false

Data Types

RoutingDecision

Represents a complete routing decision with its outcome:

decision := &memory.RoutingDecision{
    Timestamp:  time.Now(),
    APIKeyHash: "sha256:abc123",
    Request: memory.RequestInfo{
        Model:         "auto",
        Intent:        "coding",
        ContentHash:   "sha256:def456",
        ContentLength: 1234,
    },
    Routing: memory.RoutingInfo{
        Tier:          "semantic",
        SelectedModel: "claudecli:claude-sonnet-4",
        Confidence:    0.92,
        LatencyMs:     15,
    },
    Outcome: memory.OutcomeInfo{
        Success:        true,
        ResponseTimeMs: 2340,
        QualityScore:   0.88,
    },
}
UserPreferences

Represents learned preferences for a specific API key:

prefs := &memory.UserPreferences{
    APIKeyHash:  "sha256:abc123",
    LastUpdated: time.Now(),
    ModelPreferences: map[string]string{
        "coding":    "claudecli:claude-sonnet-4",
        "reasoning": "geminicli:gemini-2.5-pro",
    },
    ProviderBias: map[string]float64{
        "ollama":    0.5,
        "claudecli": 0.3,
    },
    CustomRules: []memory.PreferenceRule{
        {
            Condition: "intent == 'coding'",
            Model:     "claudecli:claude-sonnet-4",
            Priority:  100,
        },
    },
}
Quirk

Represents a known provider issue and its workaround:

quirk := &memory.Quirk{
    Provider:   "ollama",
    Issue:      "Connection timeout on first request after idle",
    Workaround: "Send warmup request on startup",
    Discovered: time.Now(),
    Frequency:  "3/10 startups",
    Severity:   "medium",
}

Security

The memory system implements several security measures:

  • API Key Hashing: API keys are hashed using SHA-256 and never stored in plaintext
  • File Permissions: All files are created with restrictive permissions (0600 for files, 0700 for directories)
  • PII Sanitization: Personal information is sanitized before storage
  • Encryption: Optional encryption at rest for sensitive data

Performance

The memory system is designed for minimal performance impact:

  • Async Writes: All writes are asynchronous and non-blocking
  • Append-Only: Routing history uses JSONL format for efficient appends
  • Caching: Frequently accessed data is cached in memory
  • Batch Processing: Analytics are computed in batches

Target performance metrics:

  • Memory append: < 5ms
  • Memory read: < 10ms
  • Memory query: < 50ms

Testing

Run the tests:

go test -v ./internal/memory/

Run with coverage:

go test -v -cover ./internal/memory/

Requirements Validation

This implementation validates the following requirements:

  • FR-1.1: Persistent Storage - Creates .switchailocal/memory/ directory structure
  • FR-1.2: Memory Types - Defines all core types (RoutingDecision, UserPreferences, Quirk, etc.)

Next Steps

After implementing the directory structure and types, the next tasks are:

  1. Implement routing history store (JSONL append-only storage)
  2. Implement provider quirks tracker (Markdown format)
  3. Implement user preferences system (JSON per API key)
  4. Create unified memory manager
  5. Integrate with Cortex Router

)

func main() {
	config := memory.DefaultMemoryConfig()

	fmt.Printf("Enabled: %v\n", config.Enabled)
	fmt.Printf("Base directory: %s\n", config.BaseDir)
	fmt.Printf("Retention days: %d\n", config.RetentionDays)
	fmt.Printf("Max log size (MB): %d\n", config.MaxLogSizeMB)
	fmt.Printf("Compression: %v\n", config.Compression)

}

Output:
Enabled: false
Base directory: .switchailocal/memory

package main

import (
	"fmt"
	"log"
	"os"
	"path/filepath"

	"github.com/traylinx/switchAILocal/internal/memory"
)

func main() {
	// Create a temporary directory for this example
	tmpDir, err := os.MkdirTemp("", "memory-example-*")
	if err != nil {
		log.Fatal(err)
	}
	defer os.RemoveAll(tmpDir)

	// Create and initialize directory structure
	baseDir := filepath.Join(tmpDir, ".switchailocal", "memory")
	ds := memory.NewDirectoryStructure(baseDir)

	if err := ds.Initialize(); err != nil {
		log.Fatal(err)
	}

	// Get paths to various components
	fmt.Println("Routing history:", filepath.Base(ds.GetRoutingHistoryPath()))
	fmt.Println("Provider quirks:", filepath.Base(ds.GetProviderQuirksPath()))
	fmt.Println("User preferences dir:", filepath.Base(ds.GetUserPreferencesDir()))
	fmt.Println("Daily logs dir:", filepath.Base(ds.GetDailyLogsDir()))
	fmt.Println("Analytics dir:", filepath.Base(ds.GetAnalyticsDir()))

}

Output:
Routing history: routing-history.jsonl
Provider quirks: provider-quirks.md
User preferences dir: user-preferences
Daily logs dir: daily
Analytics dir: analytics

func (*QuirksStore) GetQuirksByFrequency 

func (qs *QuirksStore) GetQuirksByFrequency(frequencyPattern string) ([]*Quirk, error)

GetQuirksByFrequency retrieves quirks that match a specific frequency pattern. This is useful for finding quirks that occur frequently.

func NewRoutingHistoryStore 

func NewRoutingHistoryStore(filePath string) (*RoutingHistoryStore, error)

NewRoutingHistoryStore creates a new routing history store. It initializes the async write queue and starts the background writer.

func (*RoutingHistoryStore) Close 

func (rhs *RoutingHistoryStore) Close() error

Close gracefully shuts down the routing history store. It waits for all pending writes to complete before closing the file.

func (*RoutingHistoryStore) Count 

func (rhs *RoutingHistoryStore) Count() (int, error)

Count returns the total number of routing decisions in the history.

func (*RoutingHistoryStore) GetAllHistory 

func (rhs *RoutingHistoryStore) GetAllHistory(limit int) ([]*RoutingDecision, error)

GetAllHistory retrieves all routing history without filtering. The limit parameter controls the maximum number of results returned (most recent first).

func (*RoutingHistoryStore) GetHistory 

func (rhs *RoutingHistoryStore) GetHistory(apiKeyHash string, limit int) ([]*RoutingDecision, error)

GetHistory retrieves routing history for a specific API key. It reads the entire history file and filters by API key hash. The limit parameter controls the maximum number of results returned (most recent first).

func (*RoutingHistoryStore) RecordRouting
