docs: add Docker Hub publish workflow and git mirror remotes

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

+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).

+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Infrastructure
+
+| Role | Host | Access |
+|------|------|--------|
+| Source (deb9) | 10.0.0.48 | `ssh deb9` — `/home/n8n/vera-ai/` |
+| Production (deb8) | 10.0.0.46 | `ssh deb8` — runs vera-ai in Docker |
+| Gitea | 10.0.0.61:3000 | `SpeedyFoxAi/vera-ai-v2`, HTTPS only (SSH disabled) |
+
+User `n8n` on deb8/deb9. SSH key `~/.ssh/vera-ai`. Gitea credentials in `~/.netrc`.
+
+## Git Workflow
+
+Three locations — all point to `origin` on Gitea:
+
+```
+local (/home/adm1n/claude/vera-ai)  ←→  Gitea (10.0.0.61:3000)  ←→  deb9 (/home/n8n/vera-ai)
+        ↓                                                                   ↓
+  github/gitlab                                                  deb8 (scp files + docker build)
+  (mirrors)
+```
+
+```bash
+# Edit on deb9, commit, push
+ssh deb9
+cd /home/n8n/vera-ai
+git pull origin main              # sync first
+git add -p && git commit -m "..."
+git push origin main
+
+# Pull to local working copy
+cd /home/adm1n/claude/vera-ai
+git pull origin main
+
+# Deploy to production (deb8 has no git repo — scp files then build)
+scp app/*.py n8n@10.0.0.46:/home/n8n/vera-ai/app/
+ssh deb8 'cd /home/n8n/vera-ai && docker compose build && docker compose up -d'
+```
+
+## Publishing (Docker Hub + Git Mirrors)
+
+Image: `mdkrushr/vera-ai` on Docker Hub. Build and push from deb8:
+
+```bash
+ssh deb8
+cd /home/n8n/vera-ai
+docker build -t mdkrushr/vera-ai:2.0.4 -t mdkrushr/vera-ai:latest .
+docker push mdkrushr/vera-ai:2.0.4
+docker push mdkrushr/vera-ai:latest
+```
+
+The local repo has two mirror remotes for public distribution. After committing and pushing to `origin` (Gitea), mirror with:
+
+```bash
+git push github main --tags
+git push gitlab main --tags
+```
+
+| Remote | URL |
+|--------|-----|
+| `origin` | `10.0.0.61:3000/SpeedyFoxAi/vera-ai-v2` (Gitea, primary) |
+| `github` | `github.com/speedyfoxai/vera-ai` |
+| `gitlab` | `gitlab.com/mdkrush/vera-ai` |
+
+## Build & Run (deb8, production)
+
+```bash
+ssh deb8
+cd /home/n8n/vera-ai
+docker compose build
+docker compose up -d
+docker logs vera-ai --tail 30
+curl http://localhost:11434/                   # health check
+curl -X POST http://localhost:11434/curator/run  # trigger curation
+```
+
+## Tests (deb9, source)
+
+```bash
+ssh deb9
+cd /home/n8n/vera-ai
+python3 -m pytest tests/                                          # all tests
+python3 -m pytest tests/test_utils.py                             # single file
+python3 -m pytest tests/test_utils.py::TestParseCuratedTurn::test_single_turn  # single test
+python3 -m pytest tests/ --cov=app --cov-report=term-missing      # with coverage
+```
+
+Tests are unit-only — no live Qdrant/Ollama required. `pytest.ini` sets `asyncio_mode=auto`. Shared fixtures with production-realistic data in `tests/conftest.py`.
+
+Test files and what they cover:
+
+| File | Covers |
+|------|--------|
+| `tests/test_utils.py` | Token counting, truncation, memory filtering/merging, `parse_curated_turn`, `load_system_prompt`, `build_augmented_messages` |
+| `tests/test_config.py` | Config defaults, TOML loading, `CloudConfig`, env var overrides |
+| `tests/test_curator.py` | JSON parsing, `_is_recent`, `_format_raw_turns`, `_format_existing_memories`, `_call_llm`, `_append_rule_to_file`, `load_curator_prompt`, full `run()` scenarios |
+| `tests/test_proxy_handler.py` | `clean_message_content`, `handle_chat_non_streaming`, `debug_log`, `forward_to_ollama` |
+| `tests/test_integration.py` | FastAPI health check, `/api/tags` (with cloud models), `/api/chat` round-trips (streaming + non-streaming), curator trigger, proxy passthrough |

+## Architecture
+
+```
+Client → Vera-AI :11434 → Ollama :11434
+               ↓↑
+          Qdrant :6333
+```
+
+Vera-AI is a FastAPI proxy. Every `/api/chat` request is intercepted, augmented with memory context, forwarded to Ollama, and the response Q&A is stored back in Qdrant.
+
+### 4-Layer Context System (`app/utils.py:build_augmented_messages`)
+
+Each chat request builds an augmented message list in this order:
+
+1. **System** — caller's system prompt passed through; `prompts/systemprompt.md` appended if non-empty (if empty, caller's prompt passes through unchanged; if no caller system prompt, vera's prompt used alone)
+2. **Semantic** — curated AND raw Q&A pairs from Qdrant matching the query (score ≥ `semantic_score_threshold`, up to `semantic_token_budget` tokens). Searches both types to avoid a blind spot where raw turns fall off the recent window before curation runs.
+3. **Recent context** — last 50 turns from Qdrant (server-sorted by timestamp via payload index), oldest first, up to `context_token_budget` tokens. Deduplicates against Layer 2 results to avoid wasting token budget.
+4. **Current** — the incoming messages (non-system) passed through unchanged
+
+The system prompt is **never truncated**. Semantic and context layers are budget-limited and drop excess entries silently.
+
+### Memory Types in Qdrant
+
+| Type | When created | Retention |
+|------|-------------|-----------|
+| `raw` | After each chat turn | Until curation runs |
+| `curated` | After curator processes `raw` | Permanent |
+
+Payload format: `{type, text, timestamp, role, content}`. Curated entries use `role="curated"` with text formatted as `User: ...\nAssistant: ...\nTimestamp: ...`, which `parse_curated_turn()` deserializes back into proper message role pairs at retrieval time.
+
+### Curator (`app/curator.py`)
+
+Scheduled via APScheduler at `config.run_time` (default 02:00). Automatically detects day 01 of month for monthly mode (processes ALL raw) vs. daily mode (last 24h only). Sends raw memories to `curator_model` LLM with `prompts/curator_prompt.md`, expects JSON response:
+
+```json
+{
+  "new_curated_turns": [{"content": "User: ...\nAssistant: ..."}],
+  "permanent_rules": [{"rule": "...", "target_file": "systemprompt.md"}],
+  "deletions": ["uuid1", "uuid2"],
+  "summary": "..."
+}
+```
+
+`permanent_rules` are appended to the named file in `prompts/`. After curation, all processed raw entries are deleted.
+
+### Cloud Model Routing
+
+Optional `[cloud]` section in `config.toml` routes specific model names to an OpenRouter-compatible API instead of Ollama. Cloud models are injected into `/api/tags` so clients see them alongside local models.
+
+```toml
+[cloud]
+enabled = true
+api_base = "https://openrouter.ai/api/v1"
+api_key_env = "OPENROUTER_API_KEY"
+[cloud.models]
+"gpt-oss:120b" = "openai/gpt-4o"
+```
+
+### Key Implementation Details
+
+- **Config loading** uses stdlib `tomllib` (read-only, Python 3.11+). No third-party TOML dependency.
+- **QdrantService singleton** lives in `app/singleton.py`. All modules import from there — `app/utils.py` re-exports via `from .singleton import get_qdrant_service`.
+- **Datetime handling** uses `datetime.now(timezone.utc)` throughout. No `utcnow()` calls. Stored timestamps are naive UTC with "Z" suffix; comparison code strips tzinfo for naive-vs-naive matching.
+- **Debug logging** in `proxy_handler.py` uses `portalocker` for file locking under concurrent requests. Controlled by `config.debug`.
+
+## Configuration
+
+All settings in `config/config.toml`. Key tuning knobs:
+
+- `semantic_token_budget` / `context_token_budget` — controls how much memory gets injected
+- `semantic_score_threshold` — lower = more (but less relevant) memories returned
+- `curator_model` — model used for daily curation (needs strong reasoning)
+- `debug = true` — enables per-request JSON logs written to `logs/debug_YYYY-MM-DD.log`
+
+Environment variable overrides: `VERA_CONFIG_DIR`, `VERA_PROMPTS_DIR`, `VERA_LOG_DIR`.

Vera-AI	5b44ff16ac	docs: add Docker Hub publish workflow and git mirror remotes	2026-04-01 17:49:03 -05:00
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. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-01 16:20:35 -05:00
Claude Code	6154e7974e	fix: add debug log file locking, improve error logging, validate cloud API key - Add portalocker file locking to debug_log() to prevent interleaved entries - Add exc_info=True to curator _call_llm error logging for stack traces - Add debug log message on JSON parse fallback in _parse_json_response - Warn when cloud is enabled but API key env var is not set Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-01 16:15:56 -05:00
Claude Code	cbe12f0ebd	chore: remove dead calculate_token_budget, fix hardcoded timestamp Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-01 16:13:40 -05:00
Claude Code	9fa5d08ce0	refactor: consolidate duplicate QdrantService singleton into singleton.py Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-01 16:12:21 -05:00
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. Fixes leading \n\n when no caller system msg. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-01 16:10:24 -05:00
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.

Claude Code	9774875173	fix: correct test_curator mock strategy and list content test behavior - make_curator() now patches app.curator.load_curator_prompt directly instead of env var, since PROMPTS_DIR is a module-level constant set at import time - _append_rule_to_file tests patch app.curator.PROMPTS_DIR via patch.object - test_list_content: document that passing a list raises TypeError (expected) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-03-31 19:32:27 -05:00
Claude Code	bfd0221928	test: expand coverage to 70%+ — add utils, config, curator, proxy, integration tests - Extend test_utils.py: filter_memories_by_time, merge_memories, calculate_token_budget, build_augmented_messages (mocked) - Extend test_config.py: Config.load() with TOML via tmp_path, CloudConfig helpers, env var api_key - Add test_curator.py: _parse_json_response, _is_recent, _format_raw_turns, _append_rule_to_file - Add test_proxy_handler.py: clean_message_content, handle_chat_non_streaming (mocked httpx+qdrant) - Add test_integration.py: health check, /api/tags, /api/chat non-streaming + streaming via TestClient - Add pytest.ini (asyncio_mode=auto), add pytest-cov to requirements.txt Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-03-31 19:19:49 -05:00
