make fmt and make fmt-check now cover the Markdown files with prettier as well as the Go source: prettier 3.8.1 pinned in package.json and yarn.lock, four-space indents and proseWrap always in .prettierrc, all three copied unchanged from the sneak/prompts templates. script/bootstrap adds pinned node (through nvm from a hash-checked archive when none is installed), yarn and prettier after the pinned Go. README.md is reformatted by make fmt and its Entrypoints section says what each step needs.
Model: opus-5-5
script/cibuild runs script/bootstrap on the Gitea runner, which has Docker and git but no Go, and bootstrap could not install it: its apt path never ran apt-get update. Bootstrap now installs Go at the version in the Dockerfile's golang image from go.dev, checked against sha256 values in the script, into ~/.local/go whenever the go first on PATH reports another version; the Makefile and the fmt, fmt-check and precommit scripts put ~/.local/go/bin first on their PATH. apt-get update runs once before the first apt install. Bumping the golang digest now means bumping GO_VERSION and its four hashes.
Partially verified: checked in a clean ubuntu:24.04 container, not yet on the Gitea runner.

The module, the script entrypoints and Makefile, Docker-only linting, the mnemonic sources in the specified order with their refusals, the BIP-85 derivation, and keyfunc ssh pub and priv with the README test vectors as tests. Two review rounds; the second passed with no findings.
