Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Week 4 repository guide

## Purpose and architecture

This directory contains a small FastAPI + SQLite developer command center.

- `backend/app/main.py`: application entry point, startup, static mount, router registration.
- `backend/app/routers/notes.py`: note list/create/search/read/update/delete endpoints.
- `backend/app/routers/action_items.py`: action-item list/create/complete endpoints.
- `backend/app/schemas.py`: Pydantic request validation and response contracts.
- `backend/app/models.py`: SQLAlchemy persistence models.
- `backend/app/db.py`: engine, sessions, and one-time seed loading from `data/seed.sql`.
- `backend/app/services/extract.py`: pure note action/tag extraction.
- `backend/tests/`: isolated API and service tests.
- `frontend/`: dependency-free HTML/CSS/JavaScript client served at `/`.
- `docs/TASKS.md`: product backlog; `docs/API.md`: public HTTP contract.

Request flow: browser → FastAPI router → Pydantic schema → SQLAlchemy session → SQLite. The dependency commits successful requests and rolls back exceptions.

How to install

The exact contents, by fingerprint
mdr add lucaswang81/cs146s_cn/_assignments/2025 fall/week4/CLAUDE.md@sha256:35c90ef5b040eeeb

The line at the top of this page pins the label git:20261008.c3bcd6c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
