 ## Unreleased
 
+## 0.2.5 - Portable Packaging and Reproducibility Artifacts
+
+This release makes the zero-account demo portable beyond a source checkout and
+publishes the project as an installable Python distribution. It also packages
+the reproducibility artifacts added after v0.2.4.
+
+### Packaging and first run
+
+- Packaged the deterministic small demo config inside the `mlquant` wheel.
+- Made `mlquant demo` resolve its bundled config when `--config` is omitted, so
+  it can run from any working directory after installation.
+- Preserved explicit `--config PATH` behavior for repository and custom runs.
+- Added regression coverage for isolated-directory execution and configuration
+  synchronization.
+- Modernized package license metadata for current PyPI tooling.
+
 ### Hugging Face artifacts
 
 - Added a deterministic exporter for a viewer-ready synthetic OHLCV dataset and

   safety boundary that rejects non-synthetic configs.
 - Documented the authenticated upload and post-upload verification workflow.
 
+### Documentation and contributor evidence
+
+- Linked the live Hugging Face dataset and model to the paper metadata.
+- Refreshed the Chinese project landing page with downloadable artifacts,
+  v0.2.4 metric-clarity context, and contributor credit.
+- Kept the public-data and synthetic-artifact boundaries explicit: the packaged
+  demo and Hugging Face artifacts are reproducibility aids, not alpha claims.

+# mlquant
+
+**A reproducible PyTorch research stack for machine-learning multi-factor
+trading: 213 factors, bias correction, portfolio optimization, and vectorized
+backtesting.**

+
+## Install and run
+
+```bash
+python -m pip install mlquant
+mlquant demo
+```
+
+The demo needs no market-data account or API key. It runs the deterministic
+synthetic pipeline from data generation through 213 factor dimensions, model
+training, portfolio construction, cost-aware backtesting, and Markdown/JSON
+report generation. The default config ships inside the wheel, so the command
+works outside a repository checkout.
+
+## What is included
+
+- 204 hand-crafted factors plus 9 curated Alpha101-style factors
+- mask-aware PyTorch tensor primitives for cross-sectional panels
+- limit-up, limit-down, halt, and missing-data bias handling
+- MLP and Transformer research baselines
+- constrained Markowitz portfolio construction
+- vectorized backtesting with turnover and transaction costs
+- AkShare, Baostock, yfinance, and deterministic synthetic data paths
+- auditable public-data validation reports, including negative results

+
+## Research boundary
+
+`mlquant` is research and educational software. It is not investment advice or
+a production trading system. Synthetic smoke tests verify engineering behavior,
+not profitability. Public-data backtests depend on data quality, survivorship,
+transaction costs, slippage, and modeling assumptions and do not represent live
+or guaranteed out-of-sample performance.

+# v0.2.5 - Portable Packaging and Reproducibility Artifacts
+
+`v0.2.5` is the first PyPI release of `mlquant`. It removes a subtle packaging
+trap: the command-line entry point was installable, but its default demo config
+previously lived only in a repository checkout. The deterministic config now
+ships inside the wheel, so a fresh environment can run the advertised demo from
+any working directory.
+
+## Highlights
+
+- Install directly with `python -m pip install mlquant`.
+- Run `mlquant demo` from any directory without cloning the repository.
+- Keep explicit `mlquant demo --config PATH` behavior for custom research runs.
+- Include the deterministic small config in the wheel and test it against the
+  repository copy.
+- Include the post-v0.2.4 Hugging Face dataset/model export and documentation.
+- Modernize license metadata for current PyPI build tooling.
+
+## Verification
+
+- Built both wheel and source distribution from a clean build environment.
+- Checked both distributions with `twine check --strict`.
+- Verified the wheel contains `mlquant/configs/small.yaml`.
+- Installed the wheel in an isolated environment outside the repository.
+- Passed CI on Python 3.9, 3.10, and 3.11, including the full CLI smoke test.
+
+## Research Boundary
+
+The bundled demo uses deterministic synthetic data. It verifies installation
+and the factor-to-backtest engineering path; it is not evidence of live or
+out-of-sample trading performance and is not investment advice.
