All notable changes to Salior are documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [0.3.0] — 2026-05-11

### Added

- **Dashboard web UI** (`salior/dashboard/`)
  - `dashboard/server.py` — FastAPI-alternative via aiohttp (`salior dashboard serve`)
  - `dashboard/templates/index.html` — Dark-themed trading dashboard (wallet bar, signal feed, portfolio, order form, agent health)
  - `dashboard/static/app.js` — Vanilla JS wallet connect + live data polling (30s signals, 10s agents)
  - `dashboard/static/favicon.svg` — SVG favicon
  - API endpoints: `/api/portfolio`, `/api/signals`, `/api/performance`, `/api/wallet/connect`, `/api/wallet/session`, `/api/wallet/auth-message`, `/api/order`

- **Compute orchestration** (`salior/compute/`)
  - `compute/node_manager.py` — Node registry (YAML), SSH connect, `ping()`, `run()`, GPU filtering
  - `compute/deploy.py` — `deploy_plugin()` via rsync to remote nodes, `status_plugin()` via SSH
  - Nodes stored at `~/.salior/nodes.yaml`

- **Risk agent** (`salior/agents/risk/agent.py`)
  - `RiskAgent` — position sizing, max drawdown check, max daily loss pause
  - Rules: `MAX_POSITION_PCT=0.10`, `MAX_DRAWDOWN=0.20`, `MAX_DAILY_LOSS=0.05`
  - `pause()` / `resume()` / `is_paused()` controls for circuit breaker behavior

- **Daemon** (`salior/daemon.py`)
  - `Daemon` class — PID file at `~/.salior/run/<name>.pid`, graceful SIGTERM/SIGINT handling
  - `make_daemon(name)` factory

- **6 skills** (`salior/skills/`) — now includes:
  - `plan.md` — Task decomposition into atomic verifiable steps
  - `test.md` — Red-green-refactor, test pyramid, what to/not test

### Changed

- `salior/cli.py` — Added `dashboard serve`, `skill list`, `compute status` commands
- `agent start` now starts 4 agents: data + signal + exec + risk
- `mcp serve` fires up MCP server on configured host/port
- Skills registry now finds 6 skills (was 4)

### Fixed

- Skills registry imports (was importing schema module causing double-nesting issues)

### Known Limitations

- `exec_agent` is a stub for live trading — requires HL API wallet private key (secp256k1 ECDSA)
- `place_order` MCP tool requires wallet approval flow (frontend not wired yet)
- Risk agent position sizing needs total portfolio value from DB to be fully functional

## [0.2.0] — 2026-05-11

### Added

- **4 built-in plugins** (`plugins/`)
  - `llm_batcher/` — Batch multiple LLM calls into one request (cost + speed)
  - `backtest_engine/` — Vectorized historical backtesting on TimescaleDB candles
  - `rl_trainer/` — PPO reinforcement learning agent training (GPU node required)
  - `ml_predictor/` — scikit-learn signal enhancement model

### Changed

- `plugins/` directory now populated (was empty in v0.1.0)
- `CHANGELOG.md` added at `docs/changelog/CHANGELOG.md`

- **3 agents**
  - `salior/agents/data/agent.py` — HL WebSocket collector → TimescaleDB (candles_1m, candles_5m, trades)
  - `salior/agents/signal/agent.py` — Candles → regime + conviction → Supabase signals (60s cycle)
  - `salior/agents/exec/agent.py` — Signals → HL CLOB orders; paper mode by default (300s cycle)

- **Database layer**
  - `salior/db/schema.sql` — Full PostgreSQL + TimescaleDB schema (8 hypertables, 8 app tables)
  - `salior/db/timescale_client.py` — asyncpg client for market data (candles, trades, orderbook)
  - `salior/db/supabase_client.py` — REST client for Supabase (signals, executions, portfolio, wallet_sessions)

- **LLM client** (`salior/llm/client.py`)
  - MiniMax → OpenRouter → Local Ollama routing
  - `chat()` and `batch()` methods

- **Skills system** (`salior/skills/`)
  - 4 skills: `research.md`, `build.md`, `spec.md`, `review.md`
  - `skills/registry.py` — Discovers and renders skill markdown for agents

- **MCP server** (`salior/mcp/server.py`)
  - JSON-RPC over HTTP (`localhost:8080/mcp`)
  - 5 tools: `get_portfolio`, `get_signals`, `get_market_state`, `place_order`, `get_performance`

- **Plugin system** (`salior/plugins/__init__.py`)
  - `PluginRegistry` — discovers plugins from `plugins/` directory
  - `dispatch(plugin, method, params)` — runs plugin as subprocess

- **Wallet connect** (`salior/wallet/connect.py`)
  - EIP-4361 sign-in message generation
  - 180-day session storage via Supabase
  - Rabby + MetaMask compatible (both inject `window.ethereum`)

- **CLI** (`salior/cli.py`)
  - `salior status` — print config
  - `salior db init` — apply schema.sql
  - `salior agent start` — run data + signal agents
  - `salior mcp serve` — start MCP server
  - `salior plugin list` — show available plugins

### Changed

- Project structure: `salior/` Python package at repository root (no nested `src/`)
- `pyproject.toml` — hatch build, click CLI entrypoint, all dependencies declared

### Fixed

- `wallet/connect.py` — syntax error in auth message f-string (triple-quote bleed)

### Known Limitations

- `exec_agent` is a stub for live trading — requires HL API wallet private key (secp256k1 ECDSA)
- Dashboard web UI not yet built
- No risk agent (`agents/risk/`)
- `place_order` MCP tool requires wallet approval flow (frontend not wired yet)
