 ## [Unreleased]
 
+### Changed
+- **License changed from Apache 2.0 to AGPL v3** to protect against proprietary cloud hosting of the codebase. Dual-licensing path preserved for future commercial license.
+
 ### Added
+- `NOTICE` file documenting the license change, prior license, and rationale
+- `CONTRIBUTING.md` with Contributor License Agreement (CLA) requirement
+- `benchmarks/semantic_search_bench.py` — latency benchmarks for semantic search across scale tiers (500–10K entries)
 - **PR label automation** (`pr-labels.yml`): GitHub Actions workflow that automates label transitions — resets to "Awaiting CI" on push, promotes to "Ready for QA" when CI passes, cleans up stale labels when actors pick up tasks

+# Contributing to mcp-awareness
+
+Thank you for your interest in contributing to mcp-awareness!
+
+## Contributor License Agreement (CLA)
+
+Before we can accept your contribution, you must agree to the Contributor
+License Agreement. This is required because mcp-awareness uses dual licensing:
+
+- **Open source**: AGPL-3.0-or-later (this repository)
+- **Commercial**: A separate commercial license for organizations that cannot
+  use AGPL-licensed software
+
+The CLA grants the project maintainer (Chris Means) the right to sublicense
+your contributions under any license, including proprietary. This preserves
+the ability to offer both the open-source AGPL and commercial license options.
+It does **not** transfer your copyright — you retain full ownership of your
+contribution.
+
+### How to sign
+
+When you open your first pull request, you will be asked to sign the CLA.
+This is a one-time requirement.
+
+## Development setup
+
+```bash
+pip install -e ".[dev]"    # install with dev dependencies
+python -m pytest tests/    # run tests (requires Docker for Postgres)
+ruff check src/ tests/     # lint
+ruff format src/ tests/    # format
+mypy src/mcp_awareness/    # type check
+```
+
+## Pull request guidelines
+
+- One concern per PR — don't mix unrelated changes
+- Add changelog entries under `[Unreleased]` in `CHANGELOG.md`
+- Update `README.md` if your change affects documented features or counts
+- Update `docs/data-dictionary.md` if schema changed
+- Every PR must include a `## QA` section with manual test steps
+- CI runs pytest, ruff, and mypy automatically
+
+## Code style
+
+- Python 3.10+, strict mypy
+- Ruff for linting and formatting (configured in `pyproject.toml`)
+- 100-character line length
