# Update

# `fluffbuzz update`

Safely update FluffBuzz and switch between stable/beta/dev channels.

If you installed via **npm/pnpm/bun** (global install, no git metadata),
updates happen via the package-manager flow in [Updating](/install/updating).

## Usage

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
fluffbuzz update
fluffbuzz update status
fluffbuzz update wizard
fluffbuzz update --channel beta
fluffbuzz update --channel dev
fluffbuzz update --tag beta
fluffbuzz update --tag main
fluffbuzz update --dry-run
fluffbuzz update --no-restart
fluffbuzz update --yes
fluffbuzz update --json
fluffbuzz --update
```

## Options

* `--no-restart`: skip restarting the Gateway service after a successful update.
* `--channel <stable|beta|dev>`: set the update channel (git + npm; persisted in config).
* `--tag <dist-tag|version|spec>`: override the package target for this update only. For package installs, `main` maps to `github:fluffbuzz/fluffbuzz#main`.
* `--dry-run`: preview planned update actions (channel/tag/target/restart flow) without writing config, installing, syncing plugins, or restarting.
* `--json`: print machine-readable `UpdateRunResult` JSON, including
  `postUpdate.plugins.integrityDrifts` when npm plugin artifact drift is
  detected during post-update plugin sync.
* `--timeout <seconds>`: per-step timeout (default is 1200s).
* `--yes`: skip confirmation prompts (for example downgrade confirmation)

Note: downgrades require confirmation because older versions can break configuration.

## `update status`

Show the active update channel + git tag/branch/SHA (for source checkouts), plus update availability.

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
fluffbuzz update status
fluffbuzz update status --json
fluffbuzz update status --timeout 10
```

Options:

* `--json`: print machine-readable status JSON.
* `--timeout <seconds>`: timeout for checks (default is 3s).

## `update wizard`

Interactive flow to pick an update channel and confirm whether to restart the Gateway
after updating (default is to restart). If you select `dev` without a git checkout, it
offers to create one.

Options:

* `--timeout <seconds>`: timeout for each update step (default `1200`)

## What it does

When you switch channels explicitly (`--channel ...`), FluffBuzz also keeps the
install method aligned:

* `dev` → ensures a git checkout (default: `~/fluffbuzz`, override with `FLUFFBUZZ_GIT_DIR`),
  updates it, and installs the global CLI from that checkout.
* `stable` → installs from npm using `latest`.
* `beta` → prefers npm dist-tag `beta`, but falls back to `latest` when beta is
  missing or older than the current stable release.

The Gateway core auto-updater (when enabled via config) reuses this same update path.

For package-manager installs, `fluffbuzz update` resolves the target package
version before invoking the package manager. If the installed version exactly
matches the target and no update-channel change needs to be persisted, the
command exits as skipped before package install, plugin sync, completion refresh,
or gateway restart work.

## Git checkout flow

Channels:

* `stable`: checkout the latest non-beta tag, then build + doctor.
* `beta`: prefer the latest `-beta` tag, but fall back to the latest stable tag
  when beta is missing or older.
* `dev`: checkout `main`, then fetch + rebase.

High-level:

1. Requires a clean worktree (no uncommitted changes).
2. Switches to the selected channel (tag or branch).
3. Fetches upstream (dev only).
4. Dev only: preflight lint + TypeScript build in a temp worktree; if the tip fails, walks back up to 10 commits to find the newest clean build.
5. Rebases onto the selected commit (dev only).
6. Installs deps with the repo package manager. For pnpm checkouts, the updater bootstraps `pnpm` on demand (via `corepack` first, then a temporary `npm install pnpm@10` fallback) instead of running `npm run build` inside a pnpm workspace.
7. Builds + builds the Control UI.
8. Runs `fluffbuzz doctor` as the final “safe update” check.
9. Syncs plugins to the active channel (dev uses bundled plugins; stable/beta uses npm) and updates npm-installed plugins.

If an exact pinned npm plugin update resolves to an artifact whose integrity
differs from the stored install record, `fluffbuzz update` aborts that plugin
artifact update instead of installing it. Reinstall or update the plugin
explicitly only after verifying that you trust the new artifact.

If pnpm bootstrap still fails, the updater now stops early with a package-manager-specific error instead of trying `npm run build` inside the checkout.

## `--update` shorthand

`fluffbuzz --update` rewrites to `fluffbuzz update` (useful for shells and launcher scripts).
