## Projects
### Foundations Projects
> **Start here if this is your first time coding.** The Foundations tier is *pre-beginner* — for someone who has never written Python, has barely used a terminal, and is new to cybersecurity. Source files are heavily commented as a teaching aid, and every `learn/` folder explains concepts from zero.
>
> **What makes Foundations different:**
> - **Single-file projects** — the entire tool lives in one readable Python file
> - **Heavy teaching comments** — every new concept is annotated inline
> - **Numpy-style docstrings** — every function documents what, why, and each parameter
> - **Extra-deep `learn/` folders** — Python features and security concepts explained from zero
> - **Production-quality code** — written to real standards, explained for beginners

## Getting Started
Each project lives in its own directory under [`PROJECTS/`](./PROJECTS) with its own README, source code, and `learn/` documentation. To explore a project:
```sh
cd PROJECTS//
# Then follow that project's README for setup and usage
```
Projects marked with a synopsis (under [`SYNOPSES/`](./SYNOPSES)) have detailed design documents available. Source-code-complete projects are indicated by the blue badge count above.
