## What it is
The WebAssembly design repository hosts high-level non-normative design documents, the phase-0 proposal issue tracker, and discussion forums for the WebAssembly standard. It is maintained by the W3C WebAssembly Community Group as the central hub for design rationale, goals, security model, and portability discussions.

## Use cases
- understand webassembly design goals and rationale
- learn the webassembly security model
- read about wasm portability across platforms
- propose a new webassembly feature or phase-0 idea
- find how wasm works outside the browser
- research nondeterminism and determinism in wasm

## When to choose
- you want authoritative background on WebAssembly's design decisions
- you are preparing a new WebAssembly proposal
- you need to understand the security or portability model
- you want to follow or join standards discussions

## When to avoid
- you need the normative specification or reference interpreter (see WebAssembly/spec)
- you need toolchains to compile to wasm
- you need runtime engine implementations or feature detection libraries

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, developer-tools
- domain: web-development, programming-languages, compilers, developer-tools
- platform: browser, cross-platform, wasm
- tags: webassembly, wasm, design-documents, specification, standards, community-group
