# Voyage playground screenshot convention (v4.3)
This directory holds reference screenshots for the Voyage playground
(`playground/voyage-playground.html`). They serve as a visual baseline for
manual review of design changes and as fixtures for the Wave 7 axe-core
Playwright spec (`tests/e2e/voyage-playground-a11y.spec.mjs`).
Screenshots are NOT auto-committed. The `tests/e2e/snapshots/` directory
(produced by Playwright in Wave 7) is the test-baseline; this directory
holds curated illustrative captures for documentation.
## Mappestruktur
```
docs/screenshots/
README.md ← this file
dashboard/ ← project-dashboard fleet-grid views
artifact-detail/ ← drill-down render of brief/plan/review
annotation/ ← gutter-badge + sidebar + active highlight states
dark-mode/ ← screenshots taken with html[data-theme="dark"]
light-mode/ ← screenshots taken with html[data-theme="light"]
```
Each subfolder contains PNGs named by feature + variant, e.g.
`dashboard/fleet-grid-with-progress-tile.png`,
`annotation/active-anchor-yellow-tint.png`.
## Hooks (window.__voyage)
The playground exposes three automation hooks for headless screenshot
scripts. They are namespaced under `window.__voyage` to avoid global
pollution:
| Method | Purpose |
|--------|---------|
| `window.__voyage.navigate(surface)` | Switch surface. `surface ∈ ['dashboard', 'detail', 'render', 'a11y']` |
| `window.__voyage.scheduleRender(state)` | Pre-populate state. `state.markdown` triggers `mountRender`; `state.artifacts` triggers `renderDashboard` |
| `window.__voyage.getProjectArtifacts()` | Returns the last-loaded `ProjectArtifacts` object (or `null`) |
The hook surface mirrors the pattern used in
`plugins/llm-security/playground/llm-security-playground.html`
(`window.__navigate`, `window.__scheduleRender`).
## Producing screenshots — Playwright headless (Wave 7+)
Wave 7 ships a Playwright spec
(`tests/e2e/voyage-playground-a11y.spec.mjs`). Reuse its setup for
screenshots:
```js
// tests/e2e/snapshot-helper.mjs (NOT committed in v4.3 — illustrative)
import { test } from '@playwright/test';
test('dashboard with all artifacts', async ({ page }) => {
await page.goto('file://' + process.cwd() + '/playground/voyage-playground.html');
await page.evaluate(() => {
window.__voyage.scheduleRender({
artifacts: {
basePath: 'demo',
brief: { path: 'brief.md', content: '...' },
plan: { path: 'plan.md', content: '...' },
review: null,
research: [],
architecture: { overview: null, gaps: null, looseFiles: [] },
progress: null,
looseFiles: [],
}
});
});
await page.screenshot({ path: 'docs/screenshots/dashboard/fleet-grid-demo.png' });
});
```
## Producing screenshots — manuelt
1. Åpne `playground/voyage-playground.html` i Chrome/Firefox.
2. Hvis du trenger et bestemt UI-state, paste relevant artifact-innhold i
textarea og trykk Render.
3. macOS: `Cmd+Shift+4`, deretter `Space` for vindu-skjermbilde.
4. Lagre med beskrivende filnavn under riktig undermappe ovenfor.
## Konvensjon for nye screenshots
- Bruk PNG, ikke JPG (lossless for tekst-tunge UIer).
- Kjør i konsistent viewport (1280×800 anbefales for desktop-baseline).
- Ta dark- og light-mode-varianter parvis når komponenten har visuelle
forskjeller mellom temaene.
- Ikke commit screenshots med personidentifiserende info eller hemmelig
artifact-innhold.

// ---- v4.3 Step 23 — screenshots-spor convention -------------------
// Expose a minimal automation surface for headless screenshot scripts
// (Wave 7 axe-spec + manual screenshot tooling). Mirrors the
// llm-security-playground.html `window.__navigate` /
// `window.__scheduleRender` pattern but namespaced under
// `window.__voyage` to avoid global pollution. All three methods are
// intentionally read-only from the outside — they wrap existing
// functions; we never expose state-mutating internals directly.
//
// Methods:
// navigate(surface) — surface ∈ ['dashboard', 'detail', 'render', 'a11y']
// scheduleRender(state) — state.markdown → mountRender; state.artifacts → renderDashboard
// getProjectArtifacts() — returns the last-loaded ProjectArtifacts object (or null)
//
// See docs/screenshots/README.md for the screenshot mappestruktur.
