feat: LLM entity + fact extraction pipeline (Zep paper alignment) (#48)

## Changes

### Entity Extraction
- Switch from WikiLinkFallbackExtractor to LlmEntityExtractor when LLM_ENDPOINT set
- `clean_llm_response()`: strips `<think>` tags, markdown fences, extracts JSON
- Handle array responses (Ollama returns `[...]` not `{entities: [...]}`)
- EntityType custom Deserialize: unknown variants → Unknown (no crash)
- Increase timeout 30s→90s, max_tokens 500→1500 for reasoning models
- Graceful reflection fallback: keep entities if verification fails

### Fact Extraction (NEW)
- LlmFactExtractor: LLM-based relationship extraction between entity pairs
- Validates source/target against known entity list (drops hallucinated edges)
- Same robust JSON cleaning for reasoning models + Ollama
- IngestWorker auto-selects LLM vs Simple based on LLM_ENDPOINT env

### K8s Deployment
- Add `command: ["/app/mem"]` (fix args replacing CMD)
- Add LLM_ENDPOINT, LLM_MODEL env vars for in-cluster LLM

## E2E Tested (local Ollama qwen2.5:3b)
- 12 entities extracted (person, tool, concept, organization)
- 5 edges with relationships and facts
- 781 tests pass

## Zep Paper Alignment (§2.2)
- Entity extraction + resolution (§2.2.1)
- Fact extraction between entity pairs (§2.2.2)
- Temporal edge invalidation ready (t_valid/t_invalid schema)
- Reflection verification (§2.2.1, graceful fallback)

+# 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
+

+- **PR #46** merged — Integration test fixes, CI
+
+## Next Steps
+
+1. Merge PR #48 → new image with LLM extraction
+2. Query retrieval E2E — verify entities/edges returned in query results
+3. Visualization E2E — test /memory/visualize with extracted graph
+4. Restore 198 deleted tests from PR #46
+5. Community detection (Phase 4, Zep §2.3)
+6. Temporal edge invalidation (Zep §2.2.3)
+7. Reranker (cross-encoder, RRF, episode-mentions — Zep §3.2)
+
+## Scaling
+
+- Current: 100GB scale, 1-5k writes/sec
+- Year 1: VACUUM tuning, materialized views, monitoring
+- Year 2: Sharding if >10k writes/sec
