+# Chainlit Community Release Engineering Guide
+
+## Version Management Strategy
+
+### Monorepo Versioning with Hatch
+- **Hatch-managed versions** using dynamic source from `__init__.py`
+- Configure per-package in `pyproject.toml`:
+  ```toml
+  [tool.hatch.version]
+  source = "regex"
+  path = "src/chainlit_<package>/__init__.py"
+  pattern = '^__version__ = "(.+)"$'
+  ```
+
+### Version Bumping Protocol
+For each package (e.g. `chainlit-sqlalchemy`):
+```bash
+# Bump specific version
+hatch version 1.2.3
+
+# Semantic increments
+hatch version minor  # 0.1.0 → 0.2.0
+hatch version micro  # 0.1.0 → 0.1.1 
+hatch version major,rc  # 1.0.0 → 2.0.0rc0
+hatch version release  # 2.0.0rc0 → 2.0.0
+```
+
+## Package Release Process
+
+### Pre-Release Validation
+1. Verify workspace integrity:
+   ```bash
+   uv sync --all-packages
+   uv run pip check
+   ```
+
+2. Run full test matrix:
+   ```bash
+   ./scripts/ci.sh
+   ```
+
+### Build Process Updates
+```bash
+# Ensure Hatch recognizes dynamic version
+uv pip install hatch
+
+# Build with version from Hatch
+uv build --no-sources --strict \
+  --exclude-extras all \
+  --build-constraint ../../constraints.txt
+```
+
+Key flags:
+- `--no-sources`: Ignore workspace sources
+- `--strict`: Fail on dependency resolution issues
+- `--exclude-extras`: Build base package only
+
+### Publishing Workflow
+1. Configure credentials:
+   ```bash
+   export UV_PUBLISH_TOKEN="pypi-xxxxxxxx"
+   ```
+
+2. Dry run validation:
+   ```bash
+   uv publish --dry-run --strict \
+     --index-url https://upload.pypi.org/legacy/
+   ```
+
+3. Publish package:
+   ```bash
+   uv publish --no-sources --strict \
+     --index-url https://upload.pypi.org/legacy/
+   ```
+
+4. Verify publication:
+   ```bash
+   uv pip install --force-reinstall chainlit-sqlalchemy==1.2.3
+   uv run python -c "from chainlit_sqlalchemy import __version__; print(__version__)"
+   ```
+
+## Workspace Management
+
+### Cross-Package Dependencies
+When package A (e.g. `pytest`) depends on package B (e.g. `sqlalchemy`):
+1. Release dependency first:
+   ```bash
+   uv publish -p packages/data_layers/sqlalchemy
+   ```
+
+2. Update dependent package constraints:
+   ```toml
+   # packages/pytest/pyproject.toml
+   dependencies = [
+     "chainlit-sqlalchemy>=1.2.3,<2.0.0"
+   ]
+   ```
+
+### Batch Publishing
+Publish all modified packages:
+```bash
+uv publish --workspace \
+  --index-url https://upload.pypi.org/legacy/ \
+  --strict
+```
+
+## Security & Compliance
+
+### PyPI Configuration
+```toml
+# Single token in root .env
+UV_PUBLISH_TOKEN="pypi-xxxxxxxx"
+```
+
+### Dependency Pinning
+Maintain `constraints.txt` in root:
+```bash
+uv pip compile requirements.txt --output-file constraints.txt \
+  --generate-hashes --no-sources
+```
+
+## Post-Release Actions
+
+1. Tag releases with package prefixes:
+   ```bash
+   git tag sqlalchemy/v1.2.3 -m "chainlit-sqlalchemy 1.2.3"
+   git push origin sqlalchemy/v1.2.3
+   ```
+
+## Troubleshooting
+
+Common Issues | Resolution 
+---|---
+`BuildError: Missing build dependency` | `uv pip install "setuptools>=65" --resolution=lowest-direct`
+`PublishError: Invalid API token` | Verify token has `pypi-` prefix and package scope
+`VersionConflict` | Run `uv sync --all-packages --upgrade`
+`FileExistsError` | Remove `dist/` and `build/` directories before rebuilding
