ace-pm b29c12d5e5 refactor(native): rename gsd_parser.rs to forge_parser.rs
Final rebrand: rename remaining Rust source file to complete the gsd → forge
transition. All parser references already use forge_parser after earlier commits.

# Pinning Node.js LTS on macOS with Homebrew
If you installed Node.js via Homebrew (`brew install node`), you're tracking the **latest current release** — which can include odd-numbered development versions (e.g. 23.x, 25.x). These aren't LTS and may have breaking changes or instability.
SF requires Node.js **v22 or later** and works best on an **LTS (even-numbered) release**. This guide shows how to pin Node 24 LTS using Homebrew.
## Check your current version
```bash
node --version
```
If this shows an odd number (e.g. `v23.x`, `v25.x`), you're on a development release.
## Install Node 24 LTS
Homebrew provides versioned formulas for LTS releases:
```bash
# Unlink the current (possibly non-LTS) version
brew unlink node
# Install Node 24 LTS
brew install node@24
# Link it as the default
brew link --overwrite node@24
```
Verify:
```bash
node --version
# Should show v24.x.x
```
## Why pin to LTS?
- **Stability** — LTS releases receive bug fixes and security patches for 30 months
- **Compatibility** — npm packages (including SF) test against LTS versions
- **No surprises** — `brew upgrade` won't jump you to an unstable development release
## Prevent accidental upgrades
By default, `brew upgrade` will upgrade all packages, which could move you off the pinned version. Pin the formula:
```bash
brew pin node@24
```
To unpin later:
```bash
brew unpin node@24
```
## Switching between versions
If you need multiple Node versions (e.g. 22 and 24), consider using a version manager instead:
- **[nvm](https://github.com/nvm-sh/nvm)** — `nvm install 24 && nvm use 24`
- **[fnm](https://github.com/Schniz/fnm)** — `fnm install 24 && fnm use 24` (faster, Rust-based)
- **[mise](https://mise.jdx.dev/)** — `mise use node@24` (polyglot version manager)
These let you set per-project Node versions via `.node-version` or `.nvmrc` files.
## Verify SF works
After pinning:
```bash
node --version # v24.x.x
npm install -g sf-run
sf --version
```
