Doc	What it is
REPO_LAYERS.md	What requires the Genesis/SGDK tree vs mixnet-only work (server/, most of clients/).
TOOLCHAINS.md	PSYQ (PS1), libdragon (N64), env vars, and where stubs live.
changelog.md	Build / release log (OzWorld, cross-asm) — fill when you complete a real build.

Also useful

• Protocol (v0): ../.cursor/.documentation/cross-net/protocol-v0.mdc — line-oriented ASCII, same wire as mixnetd.
• Shared C: clients/include/ (MIXNET_DEFAULT_PORT, MX_* tokens), clients/common/ (mixnet_line for byte streams on Genesis, N64, PS1). PS1 adds clients/psx/mixnet_navigator.c (Netscape-style “Mixnet Navigator” UI over the same protocol).
• Upstream: github.com/odelyzid/cross-dev-net — public mirror of this worktree; root README.md has build commands.
