The repo shipped no committed dev environment, so building required a working personal Nix/home-manager setup on PATH. Add a flake providing the full toolchain pinned via flake.lock: stable rust (per rust-toolchain.toml) + rustfmt/clippy/rust-analyzer, clang + mold (the linker the cargo config expects), nodejs 22, pnpm 9, tmux, git, and just. The shell sets the per-target linker/rustflags so it is self-contained and hermetic: cargo takes the first matching rustflags source (env > target > build), so this replaces any global `[build] rustflags` — in particular the nightly-only `-Z threads=8` that would otherwise break the stable toolchain — while keeping the fast mold link. Use with `nix develop` or `direnv allow` (.envrc). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
