fix: migration 009 add source_count + entity dedup index

- Add source_count INTEGER DEFAULT 1 column
- Dedup existing rows before creating unique index
- CREATE UNIQUE INDEX idx_memory_entity_project_name (project_id, name)
- Idempotent: safe to re-run

+# Poimen Memory System
+
+## Project Status
+
+**Architecture**: Temporal Knowledge Graph for Agent Memory (Zep paper alignment — arXiv:2501.13956)
+
+**Current**: Ingest pipeline with LLM entity + fact extraction working E2E. Deployed to K8s.
+
+### What Works
+- ✅ HTTP server (actix-web) with 15+ endpoints
+- ✅ LLM entity extraction (LlmEntityExtractor) — extracts person/tool/concept/org entities
+- ✅ LLM fact extraction (LlmFactExtractor) — extracts relationships between entities
+- ✅ Reasoning model support — strips `<think>` tags, markdown fences
+- ✅ Ollama + vLLM + OpenAI-compatible API support
+- ✅ Entity persistence to pgvector (memory_entity table)
+- ✅ Edge persistence (memory_edge table with temporal fields)
+- ✅ Graph query endpoints (entities, edges, BFS traversal)
+- ✅ Visualization (React Flow JSON, force-directed layout, SSE streaming)
+- ✅ JWT auth (Authentik OIDC) with RBAC
+- ✅ K8s deployment (CNPG postgres, ConfigMap, SOPS secrets)
+- ✅ CI: PR builds push :SHA tag, main merges retag :latest
+- ✅ 781 tests passing
+
+### Deployment
+- **Namespace**: `poimen`
+- **Image**: `forgejo.riotpiao.com/riotpiao-poimen/poimen-memory:latest`
+- **DB**: CNPG cluster `memory-db` (pgvector)
+- **LLM**: `reasoning-predictor.llm-serving.svc.cluster.local` (ornith:35b / qwen2.5:3b)
+- **Auth**: Authentik OIDC (`MEM_AUTH_MODE=none` for dev)
+- **Registry**: Forgejo container registry (FORGEJO_REGISTRY_USER/TOKEN secrets)
+
+### Key Env Vars
+```
+DATABASE_URL          postgresql://...
+MEM_AUTH_MODE         none|jwt|apikey
+LLM_ENDPOINT          http://localhost:11434/v1/chat/completions  (Ollama)
+LLM_MODEL             qwen2.5:3b | ornith:35b | reasoning
+LLM_API_KEY           (for authenticated LLM APIs)
+MEM_API_KEY           (server API key, fallback "test-key")
+OPENSEARCH_HOSTS      (optional, hybrid search)
+GATEWAY_URL           (optional, external queue)
+```
+
+## Rules
+
+1. **No progress markdown files.** Track via Forgejo issues + PRs only.
+2. **Obsidian vault repo**: `ssh://[email protected]:2222/rock/poimen-obesdient-memory.git`
+3. **Secrets via KSOPS**: Age-based SOPS encryption. Never commit plaintext.
+4. **Tea CLI**: `poimen` login has API token `1f717a00134f17c9d2d656c620b955e03ea41276`
+
+## Architecture (Zep Paper §2)
+
+### Three-Tier Knowledge Graph
+```
+Episode Subgraph (raw messages)
+  → Entity Subgraph (extracted entities + facts/edges)
+    → Community Subgraph (clusters, planned Phase 4)
+```
+
+### Ingest Pipeline (4 stages)
+1. **Entity extraction** — LLM extracts named entities with type + summary
+2. **Deduplication** — HashSet on normalized name
+3. **Fact extraction** — LLM extracts relationships between entity pairs
+4. **Contradiction detection** — pre-filter + review queue
+
+### Retrieval (3 methods, §3)
+- Cosine semantic similarity (pgvector HNSW)
+- BM25 full-text (OpenSearch, optional)
+- BFS graph traversal (depth 1-3)
+
+### Extractors
+- `LlmEntityExtractor`: calls LLM_ENDPOINT, parses JSON, handles reasoning models
+- `LlmFactExtractor`: takes entity list + text, extracts edges between known entities
+- `WikiLinkFallbackExtractor`: pattern-matches `[[wiki links]]` (no LLM)
+- `SimpleFactExtractor`: verb pattern matching (no LLM)
+- Selection: LLM extractors when `LLM_ENDPOINT` set, else fallbacks
+
+### LLM Response Cleaning
+`clean_llm_response()` handles:
+- `<think>...</think>` blocks (reasoning models)
+- Markdown code fences (```json ... ```)
+- Array responses (wrap in `{"entities": [...]}`)
+- Extract first JSON object from mixed text
+
