License
The tool software is MIT licensed: the engines in libs/, the native command line tools in cli/, the browser implementation in site_frontend/, and the compiled bundles your browser downloads to run a tool. Everything else on this site is all rights reserved. The full terms below are the repository's LICENSE file, embedded at build time so this page cannot drift from it.
Downloads
The grant above is only worth what can be acted on, so the site serves what it covers. Neither download phones anywhere, before or after you unpack it.
pahmoi-offline.zip(25.1 MB): the whole site as it was built, every tool included. Unpack it, serve the folder with any static file server, and the tools run in your browser with no network at all. TheOFFLINE-README.txtinside carries the one line that serves it, and the reason a browser needs that line rather than opening the page directly.pahmoi-source.tar.gz(4.1 MB): the source of everything the MIT grant covers, which is the tool engines, the native command line tools and the browser implementation. The repository stays private; this is how the licensed part of it is published.
Building it takes rustup and nothing else: the compiler version, the components and the WebAssembly target are pinned in the bundle's own rust-toolchain.toml, so the toolchain installs itself the first time you run cargo there. cargo build --release produces the command line tools in target/release/, one per tool on this site, and cargo test --workspace runs the same tests the site is built on. The browser build is optional and needs two more things, which BUILD.md inside the bundle covers along with the rest.
Full terms
SCOPE OF THIS LICENCE
=====================
This repository is private and mixed-licence. The MIT terms below are a
*declaration of what applies when a tool is published*: they publish nothing by
themselves, and as of 2026-07-30 nothing has been distributed.
The MIT licence below applies to the tool software, and only to it:
libs/ the tool engines (pure Rust cores)
cli/ the native command-line tools
site_frontend/ the browser implementation of the tools
static/pahmoi-planner3d.js the Display Planner's 3-D renderer
and to the compiled artifacts those produce and a visitor downloads to run a
tool: the WebAssembly bundle and its loader.
Everything else is **all rights reserved**: the grant is exactly the four
paths above and the artifacts they compile to, and no licence of any kind is
granted to anything outside it.
The name "pah.moi", the favicon and the site's visual identity are **not**
licensed. MIT grants no trademark rights, and none are granted separately.
One note on the boundary, so it is not mistaken for an oversight:
`libs/tools_core` and `site_frontend` also contain the cores for the toys and
the `/learn/` visualizers, physically alongside the tool cores. The MIT grant
reaches them, because a crate cannot be half-licensed. Narrowing that would
mean moving code into separate crates, not rewording this file.
