 ## 2.7.5 - Security & Platform Improvements

 ### ✨ New Features
@@ -40,6 +40,29 @@ Auto Claude is a desktop application (+ CLI) where users describe a goal and AI

 **PR target** — Always target the `develop` branch for PRs to AndyMik90/Auto-Claude, NOT `main`.

+**No console.log for debugging production issues** — `console.log` output is not visible in bundled/packaged versions of the Electron app. Use Sentry for error tracking and diagnostics in production. Reserve `console.log` for development only.
+
+## Work Approach
+
+**Investigate before speculating** — Always read the actual code before proposing root causes. Spawn agents to grep and read relevant source files before forming any hypothesis. Never guess at causes without evidence from the codebase.
+
+**Spawn agents for complex tasks** — When tackling complex tasks, spawn sub-agents/agent teams immediately rather than trying to handle everything in a single context window. Never attempt to analyze large codebases or multiple features monolithically.
+
+**Minimal fixes only** — Prefer the simplest approach (e.g., prompt-only changes, single guard clause) before suggesting multi-component solutions. If the user asks for X, implement X — don't bundle additional fixes they didn't request.
+
+## Known Gotchas
+
+**Electron path resolution** — For bug fixes in the Electron app, always check path resolution differences between dev and production builds (`app.isPackaged`, `process.resourcesPath`). Paths that work in dev often break when Electron is bundled for production — verify both contexts.
+
+### Resetting PR Review State
+
+To fully clear all PR review data so reviews run fresh, delete/reset these three things in `.auto-claude/github/`:
+
+1. `rm .auto-claude/github/pr/logs_*.json` — review log files
+2. `rm .auto-claude/github/pr/review_*.json` — review result files
+3. Reset `pr/index.json` to `{"reviews": [], "last_updated": null}`
+4. Reset `bot_detection_state.json` to `{"reviewed_commits": {}}` — this is the gatekeeper; without clearing it, the bot detector skips already-seen commits

+- **venv / .venv**: Must be recreated. Python's ``pyvenv.cfg`` discovery walks the

+- **vendor (PHP)**: Safe to symlink. Composer's autoloader uses ``__DIR__``-relative
+  paths that resolve correctly through symlinks.
+
+- **cargo target / go modules**: Skip entirely. Rust's ``target/`` dir contains
+  per-machine build artifacts that must be rebuilt. Go uses a global module cache

+Test Script for Memory Integration with LadybugDB
+=================================================
+
+This script tests the memory layer (graph + semantic search) to verify
+data is being saved and retrieved correctly from LadybugDB (embedded Kuzu).
+
+LadybugDB is an embedded graph database - no Docker required!
+
+Usage:
+    # Set environment variables first (or in .env file):
+    export GRAPHITI_ENABLED=true
+    export GRAPHITI_EMBEDDER_PROVIDER=ollama  # or: openai, voyage, azure_openai, google
+
+    # For Ollama (recommended - free, local):
+    export OLLAMA_EMBEDDING_MODEL=embeddinggemma
+    export OLLAMA_EMBEDDING_DIM=768
+
+    # For OpenAI:
+    export OPENAI_API_KEY=sk-...
+
+    # Run the test:
+    cd auto-claude
+    python integrations/graphiti/run_graphiti_memory_test.py
+
+    # Or run specific tests:
+    python integrations/graphiti/run_graphiti_memory_test.py --test connection
+    python integrations/graphiti/run_graphiti_memory_test.py --test save
+    python integrations/graphiti/run_graphiti_memory_test.py --test search
+    python integrations/graphiti/run_graphiti_memory_test.py --test ollama

+Test Script for Ollama Embedding Memory Integration
+====================================================
+
+This test validates that the memory system works correctly with local Ollama
+embedding models (like embeddinggemma, nomic-embed-text) for creating and
+retrieving memories in the hybrid RAG system.
+
+The test covers:
+1. Ollama embedding generation (direct API test)
+2. Creating memories with Ollama embeddings via GraphitiMemory
+3. Retrieving memories via semantic search
+4. Verifying the full create → store → retrieve cycle
+
+Prerequisites:
+    1. Install Ollama: https://ollama.ai/
+    2. Pull an embedding model:
+       ollama pull embeddinggemma    # 768 dimensions (lightweight)
+       ollama pull nomic-embed-text  # 768 dimensions (good quality)
+    3. Pull an LLM model (for knowledge graph construction):
+       ollama pull deepseek-r1:7b    # or llama3.2:3b, mistral:7b
+    4. Start Ollama server: ollama serve
+    5. Configure environment:
+       export GRAPHITI_ENABLED=true
+       export GRAPHITI_LLM_PROVIDER=ollama
+       export GRAPHITI_EMBEDDER_PROVIDER=ollama
+       export OLLAMA_LLM_MODEL=deepseek-r1:7b
+       export OLLAMA_EMBEDDING_MODEL=embeddinggemma
+       export OLLAMA_EMBEDDING_DIM=768
+
+NOTE: graphiti-core internally uses an OpenAI reranker for search ranking.
+      For full offline operation, set a dummy key: export OPENAI_API_KEY=dummy
+      The reranker will fail at search time, but embedding creation works.
+      For production, use OpenAI API key for best search quality.
+
+Usage:
+    cd apps/backend
+    python integrations/graphiti/run_ollama_embedding_test.py
+
+    # Run specific tests:
+    python integrations/graphiti/run_ollama_embedding_test.py --test embeddings
+    python integrations/graphiti/run_ollama_embedding_test.py --test create
+    python integrations/graphiti/run_ollama_embedding_test.py --test retrieve
