# Release Gate (Notchset): prompt.md (v1.0.0)

- id: `release-gate` · version 1.0.0 · block · pro (Pro)
- category: Application UI
- build: Base UI (one set of files; its dependencies follow the build)
- install (this build): `npx shadcn@latest add @beautiful-ui-pro/release-gate`
- npm dependencies: class-variance-authority@^0.7
- registry dependencies: utils, https://beautiful-ui.dev/r/notchset-foundation.json
- docs: https://beautiful-ui.dev/components/release-gate
- The install command carries everything this item needs (files, CSS, tokens, npm and registry dependencies). Prefer it to copying source by hand.

A release checklist that gates shipping: a rolling count of checks left, checks on a rail whose ink traces to the last consecutive pass (tick manual ones, run automatic ones, pick an owner), a notify switch, and HOLD TO SHIP on an offset plate that stays disabled until every check passes; shipped checks lock.

## Build it
- Stack: React 19 (`ref` is a plain prop), TypeScript, Tailwind CSS v4 utilities, a shadcn-initialised project with the `@/*` alias.
- Packages: `class-variance-authority@^0.7`.
- Files: `components/ui/notchset/blocks/release-gate.tsx`; shared code: `lib/beautiful-ui/notchset/instrument.tsx`, `lib/beautiful-ui/notchset/root.ts`, `lib/beautiful-ui/notchset/button-variants.ts`, `lib/beautiful-ui/notchset/switch-track.tsx`.
- Registry dependencies, installed with it automatically: shadcn `utils` (cn), `notchset-foundation`.
- Builds: one set of files for both, but its dependencies come in Base UI and Radix builds. Install the one that matches the project (see Install): a free item's bare URL installs the Base UI build of it and its dependencies.
- Exports to keep: `ReleaseGate`, and every exported type.
- CSS: the install adds the notchset foundation (tokens, keyframes, motion levels) to your global stylesheet once. Nothing to import by hand.
- Re-running `add` (or `--overwrite`) re-applies those rules: put overrides in your own CSS, never in the installed rules.
- Tokens: retheme with the `--notchset-*` custom properties (`--notchset-check`, `--notchset-control-edge`, `--notchset-draw-from`, `--notchset-ease-bloom`, `--notchset-ease-glide`, `--notchset-ease-key-down`, `--notchset-ease-key-up`, `--notchset-ease-travel`, `--notchset-fade`, `--notchset-focus-color`, `--notchset-focus-inset`, `--notchset-grow-to`, `--notchset-key-down`, `--notchset-key-up`, `--notchset-life-from`, `--notchset-life-ms`, `--notchset-node-blink`, `--notchset-node-bloom`, `--notchset-node-delay`, `--notchset-plate-color`, `--notchset-rise-from`, `--notchset-rule`, `--notchset-scan-to`, `--notchset-scroll`, `--notchset-signal`, `--notchset-sweep-to`, `--notchset-travel`). Never add Tailwind colour classes inside the component.

```tsx
import { ReleaseGate } from "@/components/ui/notchset/blocks/release-gate";
```

## Parts

| Part | data-slot | What it is for |
|---|---|---|
| `ReleaseGate` | `release-gate` | The count, the checks on their rail and the ship row. |

Style a part with `[data-slot="<slot>"]` selectors or its `className`; keep the attributes when editing.

## Sound
- Keep every `data-slot` and `data-sound` attribute: the sound layer reads them.
- Installing this item adds no audio. Nothing plays until the app mounts `SoundProvider` once (install: `npx shadcn@latest add https://beautiful-ui.dev/r/notchset-sound.json`, import from `@/components/ui/notchset/sound-provider`); `useSound()` gives `muted` and `setMuted` for a mute control. Without a provider the audio engine never loads.

## Match the original
- Read `components/ui/notchset/blocks/release-gate.tsx` as the reference implementation before changing or recreating anything, and match it: sizes, colours per theme, motion timings, copy and behaviour.
- If you deviate (a prop you can't honour, a style you changed, a dependency you swapped), say so in your reply, part by part.
- Keep the accessibility contract, the keyboard map and the motion levels listed below.

## Use it when
- release checklist, deploy gate, ship checklist, go live, launch checklist, pre-flight, rollout gate, Notchset
- A release or deploy page that must not ship until checks pass
- Mixing human sign-offs with automated checks

### Not when
- A simple to-do list: use a checklist
- Live rollout control after shipping: use your rollout view

## Mistakes
- Run the automatic checks on your server and return their real result
- Keep the hold short (about a second): it is a pause, not a test of patience

## Usage

```tsx
import { ReleaseGate } from "@/components/ui/notchset/blocks/release-gate";

export function Gate() {
  return (
    <ReleaseGate
      title="Planner v15"
      release="V15"
      checks={[
        { id: "brief", kind: "manual", title: "Brief approved", detail: "SCOPE FINAL", action: "APPROVED" },
        { id: "evals", kind: "auto", title: "Evals pass", detail: "85% OR MORE", action: "RUN EVALS", running: "RUNNING", run: async () => "PASSED · 88.9%" },
      ]}
      onShip={async (notify) => {
        const r = await fetch("/api/releases/v15/ship", { method: "POST", body: JSON.stringify({ notify }) });
        if (!r.ok) throw new Error("ship failed");
        return "LIVE ON 5%";
      }}
    />
  );
}
```

## Props

| Prop | Type | Default | What it does |
|---|---|---|---|
| `checks` | `({ kind: 'manual', action } \| { kind: 'auto', action, running, run } \| { kind: 'pick', people, picked })[]` |  | Each with id, title and detail. Automatic checks resolve run() with their passed line. |
| `title / when / release` | `string` |  | The header; release names the key (HOLD TO SHIP V15). |
| `onShip` | `(notify) => Promise<string>` |  | Ship; resolve with the line to show (LIVE ON 5%), reject to stay unshipped. |
| `defaultDone / channel / holdMs / onReset` | `string[] / string / number / () => void` |  | Checks done at first, the notify channel, the hold length (1200ms) and an optional RESET. |

## Customising
- Colours: the component reads your shadcn tokens (`--background`, `--foreground`, `--border` …), refined by the `--notchset-*` tokens. The signal colour is `--notchset-signal` (it falls back to `--destructive`). Set tokens on `:root`, or on any container to retheme one area.
- Dark mode follows the `.dark` class on an ancestor (the shadcn and next-themes convention).
- Update later by re-running the install with `--overwrite` (review the diff if you edited it). Changelog: https://beautiful-ui.dev/r/changelog.json

## Keyboard

| Keys | Action |
|---|---|
| Tab | Through the checks and the ship row |
| Space / Enter (hold) | Ship once every check passes; release early to cancel |

## Performance

- The hold steps every 16ms only while held; nothing runs while idle.

## Responsive

- Under 520px (container width) each check's action moves under its text.

## Motion inventory

| Interaction | What moves |
|---|---|
| Rail | The ink traces down to the last consecutive pass (620ms) |
| Checks | Nodes fill and their checks draw in; the ruler cells fill 30ms apart |
| Ship | Held, the key sinks onto its plate while a fill grows; then the scanner and the shipped line |

## Accessibility contract (preserve when editing)
- Manual checks are checkboxes, the owner is a radio group of named people, and NOTIFY is a switch
- The ship key is aria-disabled until every check passes and says why when pressed; it holds with the pointer or Space / Enter
- The count and every result are announced (aria-live)

## Install

```bash
npx shadcn@latest add @beautiful-ui-pro/release-gate
```

Pro item: needs the `@beautiful-ui-pro` registry in `components.json` and `BEAUTIFUL_UI_TOKEN` in `.env.local` (https://beautiful-ui.dev/account). Setup: https://beautiful-ui.dev/docs/pro. Your components.json `style` picks the build: radix-*, new-york and default get Radix, base-* gets Base UI.

## Credits
- Built on shadcn/ui (https://ui.shadcn.com)

The notchset foundation (the tokens listed above, keyframes and motion levels) installs once with the first component; its CSS is public at https://beautiful-ui.dev/r/notchset-foundation.json.
