+# Project Guidelines
+
+## Running Commands
+
+- Always use `uv run` to execute Python commands (e.g., `uv run python runVPP.py`, `uv run pytest tests/ -v`)
+- Do not use bare `python` or `pytest` — the project uses `uv` for dependency management
+- When you fix a bug or implement a feature write a test to prove that it works.
+
+## BEADS
+
+This project uses **bd** (beads) for issue tracking. Run `bd onboard` to get started.
+
+## Quick Reference
+
+```bash
+bd ready              # Find available work
+bd show <id>          # View issue details
+bd update <id> --status in_progress  # Claim work
+bd close <id>         # Complete work
+bd sync               # Sync with git
+```
+
+## Landing the Plane (Session Completion)
+
+**When ending a work session**, you MUST complete ALL steps below. Work is NOT complete until `git push` succeeds.
+
+**MANDATORY WORKFLOW:**
+
+1. **File issues for remaining work** - Create issues for anything that needs follow-up
+2. **Run quality gates** (if code changed) - Tests, linters, builds
+3. **Update issue status** - Close finished work, update in-progress items
+4. **PUSH TO REMOTE** - This is MANDATORY:
+   ```bash
+   git pull --rebase
+   bd sync
+   git push
+   git status  # MUST show "up to date with origin"
+   ```
+5. **Clean up** - Clear stashes, prune remote branches
+6. **Verify** - All changes committed AND pushed
+7. **Hand off** - Provide context for next session
+
+**CRITICAL RULES:**
+- Work is NOT complete until `git push` succeeds
+- NEVER stop before pushing - that leaves work stranded locally
+- NEVER say "ready to push when you are" - YOU must push
+- If push fails, resolve and retry until it succeeds

 ### Install dependencies
 
-Install the required dependencies from the `requirements.txt` file.
+Install the project using [uv](https://docs.astral.sh/uv/):
 
-If using `pip` then `pip install requirements.txt`.
+```bash
+uv sync --extra dev

-If using `conda` then follow these steps to create an environment with the right dependencies:
+If using `pip`:
 
 ```bash
-conda create --name Python-VPP \
-    && conda config --add channels conda-forge \
-    && conda activate Python-VPP \
