+# Poimen Memory System Architecture
+
+## Overview
+
+The Poimen Memory system is a distributed, multi-tier memory management platform designed for AI applications. It provides persistent storage, semantic search, and intelligent caching for conversations, logs, and structured data.
+
+## Core Components
+
+### 1. PostgreSQL with pgvector
+
+PostgreSQL serves as our primary data store with pgvector extension for semantic search. The system uses 768-dimensional embeddings generated by the nomic-embed-text-v2-moe model.
+
+Features:
+- HNSW indexes for fast approximate nearest neighbor search
+- Full ACID compliance with 2-node HA cluster
+- Automatic failover with 10-minute RTO
+- 10GB persistent volumes with daily backups
+
+### 2. OpenSearch Cluster
+
+OpenSearch provides full-text search and BM25 ranking. Documents are indexed with both raw text and preprocessed fields.
+
+Configuration:
+- 2-node cluster (1 master, 1 data)
+- 8GB heap per node
+- 20GB storage per node
+- Refresh interval: 10s
+- Index shards: 3, replicas: 1
+
+### 3. Memory Ingest Pipeline
+
+Records flow through a 4-stage pipeline:
+1. Source extraction (Pi sessions, Claude transcripts, doc corpus)
+2. Content routing (Magika ML classification)
+3. Type-specific compression (log, json, diff, text)
+4. Embedding generation and indexing
+
+### 4. Query Path (Hybrid Search)
+
+Queries use dual retrieval:
+- 60% pgvector semantic search (top-k nearest neighbors)
+- 40% OpenSearch BM25 ranking
+- Fusion via Reciprocal Rank Weighting (RRW)
+
+Results are re-ranked and deduplicated before LLM context window.
+
+## M3.8 Context Optimization
+
+The context optimizer runs at ingest time, improving data quality before embedding:
+
+### Compression Targets
+- Logs: 85-95% (remove timestamps, debug lines)
+- JSON: 70-90% (minify, remove verbose keys)
+- Text: 30-50% (remove markdown artifacts)
+- Diffs: 60-80% (remove context lines)
+
+### Benefits
+- Better pgvector embeddings (clean input = better semantic quality)
+- Better BM25 ranking (signal-rich text = stronger matches)
+- Reduced storage (lower bandwidth, faster queries)
+- All queries benefit (optimization happens once)
+
+## Performance Targets
+
+- Ingest latency: <1ms per record
+- Query latency: <100ms P95 (hybrid search)
+- Embedding generation: <500ms for 50-record batch
+- Indexing throughput: 1000+ records/sec
+- Search throughput: 100+ queries/sec
+
+## Monitoring & Observability
+
+### Metrics Exported
+
+Via Prometheus `/metrics` endpoint:
+- `m3_8_optimization_records_total` - records processed
+- `m3_8_optimization_compression_ratio` - overall compression %
+- `m3_8_optimization_compressor_ratio` - per-type compression
+- Query latency distribution (P50, P95, P99)
+- Embedding cache hit ratio
+
+### Logging
+
+Structured logs via tracing:
+- INFO: ingest completion, query execution, errors
+- DEBUG: compression stats, cache hits, routing decisions
+- TRACE: individual record processing
+
+## Deployment
+
+### Kubernetes
+
+Resources deployed in `poimen` namespace:
+- Deployment: memory-api (2 replicas)
+- StatefulSet: memory-db (PostgreSQL)
+- Deployment: opensearch (2 replicas)
+- ConfigMap: optimization settings
+- Secret: database credentials, API keys
+
+### Environment Variables
+
+- `MEM_CONTEXT_OPTIMIZER` - optimizer mode (on|off)
+- `MEM_COMPRESSION_TARGETS` - JSON targets per type
+- `MEM_CACHE_SIZE_MB` - compression cache size
+- `MEM_PROMETHEUS_ENABLED` - metrics export
+
+## Testing Strategy
+
+### Unit Tests (62 tests)
+- Individual compressor algorithms
+- Content routing accuracy
+- Cache behavior
+
+### Integration Tests (37 tests)
+- End-to-end ingest pipeline
+- Search quality on compressed content
+- Metrics collection accuracy
+
+### Benchmark Tests (16 tests)
+- Compression ratio validation
+- Query performance with/without optimization
+- Throughput and latency targets
+
+### Gate Tests (13 tests)
+- Safety assertions (no data loss)
+- Performance assertions (latency <3ms)
+- Quality assertions (compression targets met)
+
+## Roadmap
+
+### Current (M3.8)
+✅ Core optimizer (62 tests)
+✅ Ingest integration (5 tests)
+✅ Metrics & monitoring (7 tests)
+⏳ Benchmarks (16 tests)
+⏳ Gate verification (13 tests)
+
+### Next (M3.7.4-6)
+- Context endpoint (semantic + reference tiers)
+- Dual-write indexer (pgvector + OpenSearch)
+- Composition gate
+
+### Future (M4-M7)
+- Skill management
+- Source connectors (Obsidian, git)
+- Frontend React app
