feat: semantic search includes raw turns, deduplicate layers, fix recent turn ordering

- Layer 2 semantic search now queries both curated and raw types, closing the blind spot for turns past the 50-turn window pre-curation - Layer 3 skips turns already returned by Layer 2 to avoid duplicate context and wasted token budget - get_recent_turns uses Qdrant OrderBy for server-side timestamp sort with payload index; fallback to client-side sort if unavailable - Bump version to 2.0.4
test: expand coverage to 92% with production-realistic fixtures

+name: ssh
+description: SSH into remote servers and execute commands. Use for remote operations, file transfers, and server management.
+allowed-tools: Bash(ssh*), Bash(scp*), Bash(rsync*), Bash(sshpass*), Read, Write
+argument-hint: [host-alias]
+---
+
+## SSH Connections
+
+| Alias | Host | User | Password | Hostname | Purpose |
+|-------|------|------|----------|----------|---------|
+| `deb9` | `10.0.0.48` | `n8n` | `passw0rd` | epyc-deb9 | vera-ai source project |
+| `deb8` | `10.0.0.46` | `n8n` | `passw0rd` | epyc-deb8 | vera-ai Docker runtime |
+
+## Connection Commands
+
+**Interactive SSH:**
+```bash
+sshpass -p 'passw0rd' ssh -o StrictHostKeyChecking=no n8n@10.0.0.48
+sshpass -p 'passw0rd' ssh -o StrictHostKeyChecking=no n8n@10.0.0.46
+```
+
+**Run single command:**
+```bash
+sshpass -p 'passw0rd' ssh -o StrictHostKeyChecking=no n8n@10.0.0.48 "command"
+sshpass -p 'passw0rd' ssh -o StrictHostKeyChecking=no n8n@10.0.0.46 "command"
+```
+
+**Copy file to server:**
+```bash
+sshpass -p 'passw0rd' scp -o StrictHostKeyChecking=no local_file n8n@10.0.0.48:/remote/path
+sshpass -p 'passw0rd' scp -o StrictHostKeyChecking=no local_file n8n@10.0.0.46:/remote/path
+```
+
+**Copy file from server:**
+```bash
+sshpass -p 'passw0rd' scp -o StrictHostKeyChecking=no n8n@10.0.0.48:/remote/path local_file
+sshpass -p 'passw0rd' scp -o StrictHostKeyChecking=no n8n@10.0.0.46:/remote/path local_file
+```
+
+**Sync directory to server:**
+```bash
+sshpass -p 'passw0rd' rsync -avz -e "ssh -o StrictHostKeyChecking=no" local_dir/ n8n@10.0.0.48:/remote/path/
+sshpass -p 'passw0rd' rsync -avz -e "ssh -o StrictHostKeyChecking=no" local_dir/ n8n@10.0.0.46:/remote/path/
+```
+
+**Sync directory from server:**
+```bash
+sshpass -p 'passw0rd' rsync -avz -e "ssh -o StrictHostKeyChecking=no" n8n@10.0.0.48:/remote/path/ local_dir/
+sshpass -p 'passw0rd' rsync -avz -e "ssh -o StrictHostKeyChecking=no" n8n@10.0.0.46:/remote/path/ local_dir/
+```
+
+## Notes
+
+- Uses `sshpass` to handle password authentication non-interactively
+- `-o StrictHostKeyChecking=no` prevents host key prompts (useful for automation)
+- For frequent connections, consider setting up SSH key authentication instead of password
+
+## SSH Config (Optional)
+
+To simplify connections, add to `~/.ssh/config`:
+
+```
+Host n8n-server
+    HostName 10.0.0.48
+    User n8n
+```
+
+Then connect with just `ssh n8n-server` (still needs password or key).

+# Vera-AI Project
+
+**Persistent Memory Proxy for Ollama**
+
+> **Status:** Built and running on deb8. Goal: Validate and improve.
+
+Vera-AI sits between AI clients and Ollama, storing conversations in Qdrant and retrieving context semantically — giving AI **true memory**.
+
+## Architecture
+
+```
+Client → Vera-AI (port 11434) → Ollama
+              ↓
+           Qdrant (vector DB)
+              ↓
+           Memory Storage
+```
+
+## Key Components
+
+| File | Purpose |
+|------|---------|
+| `app/main.py` | FastAPI application entry point |
+| `app/proxy_handler.py` | Chat request handling |
+| `app/qdrant_service.py` | Vector DB operations |
+| `app/curator.py` | Memory curation (daily/monthly) |
+| `app/config.py` | Configuration loader |
+| `config/config.toml` | Main configuration file |
+
+## 4-Layer Context System
+
+1. **System Prompt** — From `prompts/systemprompt.md`
+2. **Semantic Memory** — Curated Q&A from Qdrant (relevance search)
+3. **Recent Context** — Last N conversation turns
+4. **Current Messages** — User's current request
+
+## Configuration
+
+Key settings in `config/config.toml`:
+
+```toml
+[general]
+ollama_host = "http://10.0.0.10:11434"
+qdrant_host = "http://10.0.0.22:6333"
+qdrant_collection = "memories"
+embedding_model = "snowflake-arctic-embed2"
+
+[layers]
+semantic_token_budget = 25000
+context_token_budget = 22000
+semantic_search_turns = 2
+semantic_score_threshold = 0.6
+
+[curator]
+run_time = "02:00"  # Daily curation time
+curator_model = "gpt-oss:120b"
+```
+
+## Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `APP_UID` | `999` | Container user ID |
+| `APP_GID` | `999` | Container group ID |
+| `TZ` | `UTC` | Timezone |
+| `VERA_DEBUG` | `false` | Enable debug logging |
+
+## Running
+
+```bash
+# Build and start
+docker compose build
+docker compose up -d
+
+# Check status
+docker ps
+docker logs VeraAI --tail 20
+
+# Health check
+curl http://localhost:11434/
+```
+
+## API Endpoints
+
+| Endpoint | Method | Description |
+|----------|--------|-------------|
+| `/` | GET | Health check |
+| `/api/chat` | POST | Chat completion (with memory) |
+| `/api/tags` | GET | List models |
+| `/api/generate` | POST | Generate completion |
+| `/curator/run` | POST | Trigger curation manually |
+
+## Development Workflow
+
+This project is synced with **deb9** (10.0.0.48). To sync changes:
+
+```bash
+# Pull from deb9
+sshpass -p 'passw0rd' scp -r -o StrictHostKeyChecking=no n8n@10.0.0.48:/home/n8n/vera-ai/* /home/n8n/vera-ai/
+
+# Push to deb9 (after local changes)
+sshpass -p 'passw0rd' scp -r -o StrictHostKeyChecking=no /home/n8n/vera-ai/* n8n@10.0.0.48:/home/n8n/vera-ai/
+```
+
+## Memory System
+
+- **raw** memories — Unprocessed conversation turns (until curation)
+- **curated** memories — Cleaned Q&A pairs (permanent)
+- **test** memories — Test entries (can be ignored)
+
+Curation runs daily at 02:00 and monthly on the 1st at 03:00.
+

+| deb9 | 10.0.0.48 | Source project (SSH) |
+| deb8 | 10.0.0.46 | Docker runtime |
+
+## Qdrant Collections
+
+| Collection | Purpose |
+|------------|---------|
+| `python_kb` | Python code patterns reference for this project |
+| `memories` | Conversation memory storage (default) |
+| `vera_memories` | Alternative memory collection |

Author	SHA1	Message	Date
Vera-AI	346f2c26fe	feat: semantic search includes raw turns, deduplicate layers, fix recent turn ordering - Layer 2 semantic search now queries both curated and raw types, closing the blind spot for turns past the 50-turn window pre-curation - Layer 3 skips turns already returned by Layer 2 to avoid duplicate context and wasted token budget - get_recent_turns uses Qdrant OrderBy for server-side timestamp sort with payload index; fallback to client-side sort if unavailable - Bump version to 2.0.4	2026-04-01 17:43:47 -05:00
Claude Code	de7f3a78ab	test: expand coverage to 92% with production-realistic fixtures Add conftest.py with shared fixtures, new test_qdrant_service.py covering all QdrantService methods, and expand curator/proxy/integration/utils tests to cover debug_log, forward_to_ollama, curator.run(), load_system_prompt, and health check edge cases.

Claude Code	90dd87edeb	fix: system prompt appends to caller's system message, empty = passthrough Handle all 4 combinations of caller system message and systemprompt.md correctly: append when both exist, passthrough when only one exists, omit when neither exists.

Claude Code	2801a63b11	fix: correct timestamp parsing bug - chained .replace() was stripping timezone The chained .replace("Z", "+00:00").replace("+00:00", "") calls were undoing each other, causing Z-suffixed timestamps to lose timezone info. Now strips "Z" directly and ensures naive datetime for cutoff comparison. Added regression test for old Z-suffixed timestamps.
