2. Performance Optimization​

Session Deduplication​

Documents:

Problem: Duplicate messages in session exports waste storage and processing time

Solution: Hash-based deduplication with SHA-256

Results:

Before Deduplication:
  - Total messages: 107,893
  - File size: 1.6GB (unified_messages.jsonl)
  - Processing time: 45 seconds

After Deduplication:
  - Unique messages: 7,507 (93% reduction)
  - File size: 112MB (93% smaller)
  - Processing time: 3 seconds (93% faster)
  - False positive rate: 0% (verified)

Implementation:

# Hash-based dedup
def deduplicate_messages(messages):
    seen_hashes = set()
    unique = []

    for msg in messages:
        msg_hash = hashlib.sha256(
            json.dumps(msg, sort_keys=True).encode()
        ).hexdigest()

        if msg_hash not in seen_hashes:
            seen_hashes.add(msg_hash)
            unique.append(msg)

    return unique

Key Files:

  • context-storage/unified_hashes.json - Message hash index
  • context-storage/unified_stats.json - Dedup metrics
  • context-storage/unified_messages.jsonl - Deduplicated messages

Parallel Task Execution​

Document: PARALLEL-TASK-EXECUTION-ENHANCEMENT.md (1,340 lines)

Goal: Speed up multi-step workflows by parallelizing independent tasks

Strategy:

# ❌ Sequential (slow)
result1 = read_file("file1.md")
result2 = read_file("file2.md")
result3 = git_status()
# Total: 3 × network latency

# ✅ Parallel (fast)
results = parallel_execute([
    ("Read", "file1.md"),
    ("Read", "file2.md"),
    ("Bash", "git status")
])
# Total: 1 × network latency

Results:

  • Sequential workflow: 12 seconds (3 files, 4 seconds each)
  • Parallel workflow: 5 seconds (all concurrent)
  • Improvement: 60% faster

Use Cases:

  • Reading multiple files for analysis
  • Running independent git commands
  • Validating multiple components

CODITECT Implementation:

  • Claude Code supports parallel tool calls natively
  • Used in /git-sync, /analyze-project, /test-suite commands
  • Documented in CLAUDE-4.5-GUIDE.md

JSONL Processing Optimization​

Documents:

Problem: Large JSONL session files (100MB+) slow to process

Optimizations:

  1. Streaming processing - Read line-by-line (vs loading all into memory)
  2. Hash-based lookup - O(1) duplicate detection
  3. Batch writing - Write 1000 lines at once
  4. Progress tracking - Real-time progress updates

Results:

Before:
  - Memory usage: 2.5GB
  - Processing time: 180 seconds
  - Throughput: 600 messages/second

After:
  - Memory usage: 150MB (94% reduction)
  - Processing time: 45 seconds (75% faster)
  - Throughput: 2,400 messages/second (4x)

Implementation:

def process_jsonl_streaming(input_path, output_path):
    """Stream-process JSONL file with batching."""
    seen_hashes = set()
    batch = []
    BATCH_SIZE = 1000

    with open(input_path, 'r') as infile, \
         open(output_path, 'w') as outfile:

        for line in infile:
            msg = json.loads(line)
            msg_hash = hash_message(msg)

            if msg_hash not in seen_hashes:
                seen_hashes.add(msg_hash)
                batch.append(msg)

                if len(batch) >= BATCH_SIZE:
                    write_batch(outfile, batch)
                    batch = []

        # Write remaining
        if batch:
            write_batch(outfile, batch)

3. Memory & Context Systems​

Catastrophic Forgetting Research​

Document: CATASTROPHIC-FORGETTING-RESEARCH.md (1,798 lines)

Problem: LLMs forget previous context when overloaded with new information

CODITECT Solution: Multi-Tier Memory Architecture

Tier 1: Working Memory (Claude Context Window)
  - Size: 200K tokens
  - Retention: Current session only
  - Access: Immediate

Tier 2: Session Memory (Checkpoints)
  - Size: Unlimited (files on disk)
  - Retention: Per-session (git-tagged)
  - Access: Fast (file read)

Tier 3: Episodic Memory (SQLite Database)
  - Size: 584MB (context.db)
  - Retention: Full history (all sessions)
  - Access: SQL queries (/cxq commands)

Tier 4: Semantic Memory (Knowledge Base)
  - Size: Extracted decisions/patterns
  - Retention: Permanent (version-controlled)
  - Access: Keyword/semantic search

Tier 5: Cloud Backup (GCS)
  - Size: 584MB + 112MB (db + jsonl)
  - Retention: 90 days
  - Access: Restore command

Key Patterns:

  1. Progressive Disclosure - Load only what's needed
  2. Checkpoint Recovery - Resume from any point
  3. Query-Driven Recall - Search history with /cxq
  4. Knowledge Extraction - Auto-extract learnings

Metrics:

  • Context retention: 100% (vs 0% without system)
  • Recall accuracy: 95%+ (keyword search)
  • Recovery time: <5 seconds (checkpoint restore)
  • Storage efficiency: 93% (with deduplication)

4. Multi-Tenant Architecture​

Document: MULTI-TENANT-CONTEXT-ARCHITECTURE.md

Problem: Support multiple organizations using shared CODITECT infrastructure

Solution: Schema-Based Multi-Tenancy

Architecture:
  Database: Single PostgreSQL instance
  Isolation: Schema per tenant
  Shared: Application code, infrastructure
  Isolated: Data, configurations, secrets

Tenant Schema Structure:
  tenant_acme/
    ├── users           -- Tenant-specific users
    ├── projects        -- Tenant projects
    ├── contexts        -- Session data
    └── configurations  -- Tenant settings

Shared Schema:
  public/
    ├── tenants         -- Tenant registry
    ├── billing         -- Usage tracking
    └── audit_logs      -- Cross-tenant audit

Security:

  • Row-level security (RLS) for tenant isolation
  • Service account per tenant
  • Encrypted secrets in Secret Manager
  • Audit logging for compliance

Scalability:

  • Supports 1000+ concurrent users per tenant
  • Horizontal scaling with read replicas
  • Connection pooling (PgBouncer)
  • Caching layer (Redis)

Cost Efficiency:

  • Shared infrastructure reduces costs 70%
  • Pay-per-use billing model
  • Resource quotas prevent abuse
  • Auto-scaling based on load

5. Docker Development Environment​

Documents:

Problem: Manual dev setup takes 90 minutes, error-prone

  • Portable (works on macOS/Linux/Windows)
  • Persistent (volumes for projects/configs)

Performance:

Startup time: 30 seconds (cold start)
Memory usage: 2GB RAM
Disk usage: 5GB (image + volumes)
CPU overhead: <10% (native performance)

Cross-Cutting Concerns​

Performance Best Practices​

  1. Parallel tool calling for independent operations
  2. Streaming processing for large files (100MB+)
  3. Hash-based indexing for fast lookups
  4. Batch operations (1000-record batches)
  5. Progressive disclosure to minimize context loading

Infrastructure Best Practices​

  1. Infrastructure as Code (OpenTofu/Terraform)
  2. Multi-environment strategy (dev/staging/prod)
  3. Secret management (never commit secrets)
  4. Monitoring & alerting (Cloud Monitoring)
  5. Cost optimization (right-sizing, committed use)

Security Best Practices​

  1. Least privilege IAM (service accounts only)
  2. Encryption at rest (Cloud SQL, GCS)
  3. Encryption in transit (TLS 1.3)
  4. Audit logging (Cloud Audit Logs)
  5. Vulnerability scanning (Container Analysis)
