Adds the foundations tier: three Python projects pitched at someone
who has never written Python before, ramping from a single-file hash
identifier up to the cryptographic boundary of the beginner tier.
Projects
- hash-identifier: identify ~30 hash formats by prefix, length, and
charset (one file, ~30 tests).
- http-headers-scanner: fetch a URL and grade its security headers
A–F (httpx + rich + respx, single-file scanner, 13 tests).
- password-manager: Argon2id + AES-256-GCM encrypted CLI vault with
atomic durable writes and advisory file locking (the hardest
foundations project — stepping stone into the beginner tier).
Each project ships with
- Heavily-commented source as a teaching aid (foundations-tier override
of the no-comments rule — explanations targeted at first-time readers).
- A full learn/ folder: Overview, Concepts, Architecture, line-by-line
Implementation walkthrough, Challenges.
- README with ASCII banner, badges (incl. tier + difficulty), demo
sessions, command tables, learn-folder index, see-also links.
- install.sh + justfile + uv-managed dependencies.
- pytest + ruff + mypy + pylint config, all linters at 10.00/10.
Also centralizes the docs/ exclude in .gitignore (was a per-project
list of advanced/beginner docs paths) so dev-only audit reports and
plan documents stay local across the whole repo without needing
individual entries.
