… Mac INSTALL.md step 1 told the assistant to use `brew install node` on macOS, with `nvm` as the fallback. Neither is reachable on the machine this is written for: a new Mac has no Homebrew, and nvm is a shell function, so a Node it installs is not on the path in the assistant's next command. Where brew does exist it installs the current release — 26 today, while CI covers only 20 and 22, on ubuntu-latest, with macOS never tested. The route now names the nodejs.org LTS installer, which lands in /usr/local/bin, already first on the default path, and adds the version re-check that engines: >=20 never enforces at runtime. README also promised the assistant "asks before using a supported host installation path". filocosta46#76 deliberately removed that gate — asking a person who does not know what Node is 'a dead end wearing the costume of consent' — and updated README to match. filocosta46#81, a session-privacy change, reintroduced the old sentence. This restores the agreement, describing what actually happens: the assistant waits because the installer needs a password it cannot type. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

…Homebrew Review of the first commit turned up three things it got wrong or left open. The guide sends a first-time user to the nodejs.org LTS, which is 24.19.0, while CI covered only 20 and 22 on ubuntu-latest. The advertised path therefore landed on a major no job had ever run. 24 joins the matrix so the recommendation is something the suite actually exercises. The obvious alternative — carry the install with a pinned Homebrew formula, as the 'carry the install to a working state' contract would prefer — does not work. `node@22` and `node@24` are keg-only versioned formulae: brew installs them without linking them onto the path, so the agent would install Node and `node --version` would still fail. That is worse than handing over. The macOS hand-off is the only route that is both a tested release and on the path, and step 1 now says so rather than leaving the next reader to rediscover it. Linux had a floor with no remedy: the step demands 20 or newer but told the agent to accept whatever the distribution ships, which on Debian stable is older. It now names the LTS tarball or NodeSource as the way out. Step 1 is a scannable per-platform list instead of three paragraphs, the unverified claim about the .pkg landing in /usr/local/bin is gone, and README no longer promises a hand-off on Windows and Linux, where the assistant runs the installer itself. Five assertions pin the bootstrap in the public contract. It has regressed twice already — filocosta46#76 removed the ask-before-Node gate, filocosta46#81 restored it, and the brew route outlived both — each time with CI green, because nothing tested it.

nvm official documentation nvm install current shell PATH separate shell source nvm.sh
💡 Result:
According to the official nvm documentation, nvm manages Node.js versions by modifying the PATH, MANPATH, and NODE_PATH environment variables whenever you change versions using commands like nvm use or nvm install [1][2][3]. Regarding your specific points: 1. nvm install: When you run nvm install , it installs the specified version and then automatically runs nvm use to make that version the active one in your current shell [4][5][3]. This update is local to the shell session in which the command is executed [6]. 2. Current shell vs. separate shell: nvm is a shell function, not a standalone executable [7]. Because of this, it can only modify the environment (like PATH) of the current shell process and its future child processes. It cannot reach out and modify the PATH of already-running separate shell sessions or other processes [6][7]. 3. PATH updates: The PATH is updated dynamically via internal nvm functions (such as nvm_change_path) whenever you switch versions [6][8]. This ensures that when you run node or npm, the shell resolves them to the binaries associated with the currently active nvm version [1][2]. 4. Sourcing nvm.sh: To ensure nvm is available in new shell sessions, you must source the nvm.sh script in your shell's startup profile (e.g., ~/.bashrc, ~/.bash_profile, or ~/.zshrc) [4][5]. The official installation script typically adds this block to your profile automatically [4][5]: export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")" [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm If you find that new shells are defaulting to the system's Node.js rather than your desired nvm version, verify that the nvm.sh source line is correctly configured in your profile [4][3]. You can also set a default version using the command nvm alias default [4][5].

State the shell boundary in the nvm warning.
nvm install activates Node.js in the current shell. The PATH failure occurs when the next command runs in a separate shell that did not source nvm.sh. Keep the prohibition for this pipe-based flow.

Scope the assertions to the relevant guidance sections.
The Homebrew assertion rejects only the exact text normal route: \brew install node`. A future edit could reintroduce brew install nodeas the macOS recommendation and still pass. Thenodejs.org, nvm`, and README assertions also accept unrelated mentions. Extract the Node bootstrap and macOS sections, then assert the installer recommendation and prohibition within those sections.

CI caught this, which is the point. The guard added in filocosta46#87 pinned the literal string 'installs it for you where it can'. This release legitimately reworded that sentence — filocosta46#92 made the old wording false, since the assistant no longer needs a password on macOS — and the guard failed on a change it should have allowed. A contract test that pins prose breaks on every honest edit and teaches people to weaken it. What must hold is the claim: the README says the assistant installs Node, and never reinstates the ask-before-Node gate that filocosta46#76 removed and filocosta46#81 accidentally restored.

* release: 2.0.7 Pins move to 2.0.7 across package.json, README, INSTALL, friend-setup, getting-started, and the version assertion in public-contract.test.mjs — 54 strings in six files. CHANGELOG's `## [2.0.6]` heading is deliberately left alone: it is history, and a global replace would rewrite it. Also fixes a contradiction #92 left behind. #92 changed only INSTALL.md, so README still told people 'On a Mac it points you at the official installer instead, because that step needs your administrator password' — which #92 had just made false. The README now says what the product does: the assistant installs Node for you, on macOS and Linux without a password. Releasing matters here rather than being bookkeeping: the README hands the assistant `blob/v<version>/INSTALL.md`, so a fix on main is invisible until a tag exists. Until this ships, the advertised path still sends every Apple Silicon Mac to a `.pkg` nodejs.org does not publish for arm64. Tests not run locally — this machine is deliberately without Node for a first-run install test. Verified by re-implementing public-contract.test.mjs's assertions against the edited files: 17/17. CI is the real check. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(contract): assert the Node claim, not one exact sentence CI caught this, which is the point.

Docs, one CI line, and five contract assertions. No product code.
CI: green on Node 20, 22 and 24 — including the 24 job this PR adds.
The route the assistant is given cannot work on a new Mac
INSTALL.mdstep 1 told the assistant to usebrew install nodeon macOS, withnvmas the fallback. On the machine that prose is written for, neither is reachable:brewlives at/opt/homebrew/bin/brew, reachable only via/etc/paths.d/homebrew, a file Homebrew's own installer creates.INSTALL.mdnever gives a command to install Homebrew, and does not mention that doing so needs an admin password plus Xcode Command Line Tools.nvmcannot work from an assistant. It is a shell function sourced from~/.nvm/nvm.sh, never a binary on PATH. Assistant harnesses run each command in a fresh non-login shell, so a Node installed bynvm installin one call is gone by the next — which is step 2.brew install node; Troubleshooting anddoctor's own fix string (packages/cli/src/commands/doctor.mjs:322) both say LTS from nodejs.org.Why the macOS route hands over instead of carrying the install
INSTALL.md:15-18asks the assistant to "carry the install to a working state", so the obvious fix was a pinned Homebrew formula the agent could run itself. That does not work, and the reason is now written into step 1 so it is not re-proposed:Keg-only means brew installs them without linking them onto PATH — the assistant would install Node and
node --versionwould still fail. The unpinned formula is on PATH but tracks the current release, 26.7.0, four majors past anything tested. The nodejs.org LTS.pkgis the only macOS route that is both a supported release and on PATH, and it needs the user's password. So the hand-off is a real constraint, not a shortcut.Windows (
winget) and Linux (package manager) are still carried by the assistant, and the README no longer implies otherwise.The recommended Node is now actually tested
.github/workflows/ci.ymlcoverednode: [20, 22]onubuntu-latest. Current LTS — what this guide sends a first-timer to — is 24.19.0, so the advertised path landed on a major no job had ever run.engines: ">=20"does not stop it. The matrix is now[20, 22, 24], and the new job passes.The README half was a regression, not a design difference
README.mdpromised the assistant "asks before using a supported host installation path." That gate was removed deliberately in #76:#76 updated the README to match. Then #81, a session-privacy change with no stated intent to touch this, reintroduced the old sentence. This restores agreement and describes what actually happens.
Five assertions so it cannot regress silently again
The Node bootstrap has now regressed twice with CI green, because nothing tested it.
public-contract.test.mjsnow asserts, against unwrapped prose so a reflow cannot drop it: no unpinned brew route, nodejs.org named,nvmruled out, the version re-check present, and the README wording matching INSTALL.Also fixed in review: Linux had a version floor with no remedy (the step demands ≥20 but told the agent to accept whatever the distro ships — it now names the LTS tarball or NodeSource); an unverified claim that the
.pkglands in/usr/local/binwas removed rather than shipped; and step 1 is a scannable per-platform list instead of three paragraphs.Related
#88 is closed — #89 landed the identical Antigravity registry swap plus the OpenCode bridge and the test work. Two items from it remain open and are not addressed here: the phantom-Gemini warning survives #89 (
.gemini/config/skillsis still nested under~/.gemini, and Gemini'sdetectis that bare directory), and whether Antigravity follows symlinks into that directory is undocumented.Two adjacent findings, deliberately out of scope:
~/.codex/AGENTS.override.mdsilently takes precedence overAGENTS.mdwhen present, and Cursor's global rules are Settings-UI state with no file path, so no installer can populate them.🤖 Generated with Claude Code
