Overview

Make @uiverify/playwright (archive-replay) captures deterministic so real-page visual tests stop coming back "changed" without a real change (flaky diffs). Use when driving a real page — your app under test, a staging build, or live production — and the diff flakes. A symptom-to-lever checklist for the run-to-run variation you probably have - feature flags, live data, the clock, third-party widgets, and dynamic layouts. The lever is almost always "stop the variation at record time" — the archive bakes in whatever the page was.

Deterministic Playwright captures (archive-replay)

Mental model

@uiverify/playwright captures each test's final DOM + every resource the page loaded into an archive; UI Verify re-renders and pixel-diffs that archive server-side. So:

Whatever the page was at the instant of capture is baked into the archive forever. Your job is to drive the page to one canonical state before the snapshot. UI Verify can't un-see a random A/B variant, a live feed, or a piece of lazy content that never loaded.

The snapshot fires automatically at the end of every test that passes or fails (a failed one too, so a broken page shows up as a visual change rather than vanishing from the build; a test that times out is skipped), so your beforeEach + navigation is the determinism surface. Integration is one import:

- import { test, expect } from '@playwright/test';
+ import { test, expect } from '@uiverify/playwright';

What UI Verify handles server-side (don't hand-fix these): it re-renders the archived DOM with prefers-reduced-motion emulated and fonts and images settled. So pixel-level settling — waiting on document.fonts.ready, sticky-header animation, image decode — is not your job. Your job is narrower: make sure the content and state the archive records is the same every run.

One caveat on "animations": the freeze is replay-side, via reduced-motion emulation — the archive does not bake a frozen frame. A CSS animation that honors prefers-reduced-motion freezes for free; an infinite CSS/JS animation that ignores it keeps running on replay and lands on a random frame (recipe 8), and a <canvas>/requestAnimationFrame loop is beyond the media query entirely (recipe 9). Those live inside your app, so the fix does too.

The core skill: recognize the class, then pull the lever at record time

Everything below is the same move — something rendered differently run-to-run and it wasn't a real change; find what injected the variation and pin it before the snapshot.

Symptom in the diff	Cause class	Lever
Whole page reflows; height differs between runs	Feature flag / A-B experiment rendering a different variant per load (Optimizely, LaunchDarkly, VWO, your own)	Stub the flag calls so one fixed variant renders → recipe 1
A list / feed / counts differ	Live data from an API	Mock the endpoint with a fixed response → recipe 2
Timestamps, "today", a year, a chart's day axis drift	The clock (`Date.now`) at render time	Freeze `Date` before navigation → recipe 3
A banner / chat / consent overlay appears or shifts	Third-party widget injecting DOM	Stub or dismiss it → recipe 1 + 4
Blank/placeholder where an image should be	Lazy content that never loaded, so its bytes aren't in the archive	Trigger it at record time → recipe 5
Same content, packed or ordered differently each run	Dynamic layout that reflows or reorders on its own	Mask it (or pin a fixed order/size) → recipe 6
An infinite JS animation the capturer can't stop (a charting lib's loop, a `<canvas>` spinner)	App-driven animation with no final frame	Branch the component on capture and render the end state → recipe 7
A different logo/mascot/hero or list order each run — a whole-element diff, not a pixel shift	`Math.random()` in the render body, run at SSR time in Next.js/Remix	Pin the variant on `isUIVerify()` + `UI_VERIFY=1` on the app server → recipe 10
An infinite CSS keyframe animation on a different frame	CSS animation that ignores `prefers-reduced-motion`	Honor the media query in the app's CSS → recipe 8
A `<canvas>` (particles, chart, background) diffs every run	`requestAnimationFrame` loop the media query can't reach	Draw one static frame on `isUIVerify()` → recipe 9
The capture is a skeleton / spinner, not the loaded page	Snapshot fired before the data arrived	Wait for the real content (`networkidle`) → recipe 12

Prefer removing a whole class at the source: test a build/staging with flags and third-party scripts off and rows 1 and 4 disappear before you write any code.

Recipes

1. Stub feature-flag / third-party scripts (register in beforeEach, before goto):

await page.route(/optimizely|optly|launchdarkly|segment|intercom/i, (route) =>
  route.fulfill({ status: 204, body: '' }).catch(() => undefined),
);

Use fulfill({ status: 204 }), not route.abort() — an aborted request reads as pending network activity and can hang the page's readiness wait. A 204 completes it empty: the script "loads," resolves no variant, and the page renders its control DOM. Identify the culprit by loading the page a few times and watching document.body.scrollHeight flip between values.

2. Mock live data: intercept the API route and fulfill a fixed JSON fixture — same shape every run.

await page.route('**/api/items', (route) =>
  route.fulfill({ json: fixtures.items }),
);

3. Freeze the clock (before navigation — it changes what the app renders into the DOM). Use Playwright's built-in clock so Date, Date.now(), and Date()-without-new all stay correct:

await page.clock.setFixedTime(new Date('2020-01-01T00:00:00Z'));

4. Dismiss overlays (best-effort; absent = fine):

await page.getByRole('button', { name: 'Accept All' }).click({ timeout: 4000 }).catch(() => {});

5. Trigger lazy content so its bytes land in the archive. This is the one "settle" that is yours — not for pixel-stability (UI Verify handles that) but because content that never loaded was never recorded. Scroll it into view before the snapshot:

await page.evaluate(async () => {
  for (let y = 0; y < document.body.scrollHeight; y += innerHeight) {
    scrollTo(0, y);
    await new Promise((r) => setTimeout(r, 60));
  }
  scrollTo(0, 0);
});

6. Neutralize what can't be pinned — there's no separate mask step; UI Verify diffs the archived DOM, so hide the unstable element in the DOM before the snapshot and its varying content never lands in the archive:

// target the container that reflows or reorders between runs
await page
  .locator('[data-testid="dynamic-region"]')
  .evaluateAll((els) => els.forEach((el) => (el.style.visibility = "hidden")));

7. Freeze an app-driven JS animation the capturer can't reach — an infinite charting-library loop, a <canvas> spinner with no final frame. Detect the capture in the component and render the end state. @uiverify/playwright sets a UIVerify user-agent marker and a window.__UI_VERIFY__ global at record time, so a client-side branch works on its own; if the component decides this during server-side rendering (no window yet), also set a UI_VERIFY env var when you boot the app for the record run and check it:

// in the component (your app code, not the test):
const isUIVerify = () =>
  (typeof process !== 'undefined' && !!process.env.UI_VERIFY) ||            // SSR / build time
  (typeof window !== 'undefined' &&
    (navigator.userAgent.includes('UIVerify') || '__UI_VERIFY__' in window)); // browser

<Chart isAnimationActive={!isUIVerify()} />

Boot the app with the env var for the capture run only — e.g. UI_VERIFY=1 npm start — so a server-rendered branch can see it; the browser markers cover client-side animation without it. This is the record-side of the same freeze the Storybook/Vitest skills apply in-browser.

Determinism the app itself owns (real-app cases a stub can't reach)

The recipes above pin variation from outside the app — routes, the clock, the DOM. The next five live where a stub can't reach: inside your components (a branch on isUIVerify(), recipe 7's helper, or the app's own CSS) or in what the test waits for. These are the ones that eat an afternoon if you fight them from the test, especially under SSR.

8. Infinite CSS animation lands on a random frame — a rotating illustration, a pulsing dot. The freeze is replay-side (see the mental model): the worker emulates prefers-reduced-motion: reduce and re-runs the archived CSS, so the animation stops only if the app honors that media query. Add it to the app's CSS — not the test:

@media (prefers-reduced-motion: reduce) { .rotating-logo { animation: none } }

Use animation: none, never animation-duration: 0s — 0s leaves an infinite animation on its own compositor layer and it sub-pixel-flakes (~1/100). No isUIVerify() needed here; the media query is the whole lever. (FAILED: setting reducedMotion in the test/config is a no-op at record time — the archive never bakes the computed transform, so there's nothing to freeze until replay. Don't reach for it. Also: reducedMotion is not a top-level Playwright use option anyway — it lives under use: { contextOptions: { reducedMotion: 'reduce' } } — but you don't need it at all.)

9. A <canvas> / requestAnimationFrame animation diffs every run — particles, a chart, an animated background. rrweb bakes the canvas pixels (rr_dataURL) at the instant of capture, catching a different frame each time. A media query can't reach a JS rAF loop, so branch in the component's effect:

useEffect(() => {
  if (isUIVerify()) drawOneStaticFrame();   // one deterministic frame under capture
  else startRaf();                          // the live loop for real users
}, []);

FAILED: emulating prefers-reduced-motion in the test does set matchMedia(...).matches = true in the page, but a hand-written rAF loop never reads it and keeps animating — the guard has to be in the JS.

10. A random pick made in render changes the element each run — a mascot/logo/hero image chosen by Math.random(), a shuffled list. Not a pixel shift: a different element, a large whole-element diff, every run. This is the biggest real-app time-sink. In any SSR framework (Next.js, Remix) the pick runs at server render time and the archive bakes the SSR'd choice, so a browser-side fix can't touch it. Pin the variant in the component and let real users keep the randomness:

const src = isUIVerify() ? images[0] : images[Math.floor(Math.random() * images.length)];

Because the pick is server-side, set UI_VERIFY=1 on the app server for the capture run (recipe 7) so SSR and the client agree on the fixed variant — otherwise they disagree and React throws a hydration mismatch. FAILED (do not repeat): seeding Math.random from a Playwright addInitScript fixture — it patches the browser RNG, which cannot reach a pick React already made on the server; seeded captures still rolled different sprites. (Redefining navigator.userAgent from an init script fails too — it's why the marker is set at context creation, not in-page.)

11. Even after gating the animation, a canvas/grid layout still differs — the frame is static but the square positions, particle seeds, or item order move run-to-run. The layout is drawing from the global Math.random, and seeding it globally is not enough: React and other components consume the shared sequence first, by an amount that varies with render timing, so your component gets different values each capture. Give that component its own reset-able RNG (a tiny xo

# Deterministic Playwright captures (archive-replay)

## Mental model

`@uiverify/playwright` captures each test's **final DOM + every resource the page loaded** into an
archive; UI Verify re-renders and pixel-diffs that archive server-side. So:

> Whatever the page **was at the instant of capture** is baked into the archive forever. Your job is to
> drive the page to one canonical state before the snapshot. UI Verify can't un-see a random A/B variant,
> a live feed, or a piece of lazy content that never loaded.

The snapshot fires automatically at the end of every test that passes or fails (a failed one too, so a broken
page shows up as a visual change rather than vanishing from the build; a test that times out is skipped), so your `beforeEach` + navigation *is* the
determinism surface. Integration is one import:

```diff
- import { test, expect } from '@playwright/test';
+ import { test, expect } from '@uiverify/playwright';
```

**What UI Verify handles server-side (don't hand-fix these):** it re-renders the archived DOM with
`prefers-reduced-motion` emulated and fonts and images settled. So pixel-level settling — waiting on
`document.fonts.ready`, sticky-header animation, image decode — is **not** your job. Your job is
narrower: make sure the **content and state** the archive records is the same every run.

One caveat on "animations": the freeze is **replay-side**, via reduced-motion emulation — the archive
does **not** bake a frozen frame. A CSS animation that honors `prefers-reduced-motion` freezes for free;
an **infinite** CSS/JS animation that ignores it keeps running on replay and lands on a random frame
(recipe 8), and a `<canvas>`/`requestAnimationFrame` loop is beyond the media query entirely (recipe 9).
Those live inside your app, so the fix does too.

## The core skill: recognize the class, then pull the lever at record time

Everything below is the same move — *something rendered differently run-to-run and it wasn't a real
change; find what injected the variation and pin it before the snapshot.*

| Symptom in the diff | Cause class | Lever |
|---|---|---|
| Whole page reflows; height differs between runs | **Feature flag / A-B experiment** rendering a different variant per load (Optimizely, LaunchDarkly, VWO, your own) | **Stub the flag calls** so one fixed variant renders → recipe 1 |
| A list / feed / counts differ | **Live data** from an API | **Mock the endpoint** with a fixed response → recipe 2 |
| Timestamps, "today", a year, a chart's day axis drift | **The clock** (`Date.now`) at render time | **Freeze `Date`** before navigation → recipe 3 |
| A banner / chat / consent overlay appears or shifts | **Third-party widget** injecting DOM | **Stub or dismiss** it → recipe 1 + 4 |
| Blank/placeholder where an image should be | **Lazy content** that never loaded, so its bytes aren't in the archive | **Trigger it at record time** → recipe 5 |
| Same content, packed or ordered differently each run | **Dynamic layout** that reflows or reorders on its own | **Mask** it (or pin a fixed order/size) → recipe 6 |
| An infinite JS animation the capturer can't stop (a charting lib's loop, a `<canvas>` spinner) | **App-driven animation** with no final frame | **Branch the component on capture** and render the end state → recipe 7 |
| A different logo/mascot/hero or list order each run — a whole-*element* diff, not a pixel shift | **`Math.random()` in the render body**, run at **SSR time** in Next.js/Remix | **Pin the variant on `isUIVerify()`** + `UI_VERIFY=1` on the app server → recipe 10 |
| An infinite CSS keyframe animation on a different frame | **CSS animation that ignores `prefers-reduced-motion`** | **Honor the media query in the app's CSS** → recipe 8 |
| A `<canvas>` (particles, chart, background) diffs every run | **`requestAnimationFrame` loop** the media query can't reach | **Draw one static frame on `isUIVerify()`** → recipe 9 |
| The capture is a skeleton / spinner, not the loaded page | **Snapshot fired before the data arrived** | **Wait for the real content** (`networkidle`) → recipe 12 |

Prefer removing a whole class at the source: **test a build/staging with flags and third-party scripts
off** and rows 1 and 4 disappear before you write any code.

## Recipes

**1. Stub feature-flag / third-party scripts** (register in `beforeEach`, before `goto`):
```ts
await page.route(/optimizely|optly|launchdarkly|segment|intercom/i, (route) =>
  route.fulfill({ status: 204, body: '' }).catch(() => undefined),
);
```
Use `fulfill({ status: 204 })`, **not `route.abort()`** — an aborted request reads as pending network
activity and can hang the page's readiness wait. A 204 completes it empty: the script "loads," resolves
no variant, and the page renders its control DOM. Identify the culprit by loading the page a few times
and watching `document.body.scrollHeight` flip between values.

**2. Mock live data:** intercept the API route and `fulfill` a fixed JSON fixture — same shape every run.
```ts
await page.route('**/api/items', (route) =>
  route.fulfill({ json: fixtures.items }),
);
```

**3. Freeze the clock** (before navigation — it changes what the app renders into the DOM). Use
Playwright's built-in clock so `Date`, `Date.now()`, and `Date()`-without-`new` all stay correct:
```ts
await page.clock.setFixedTime(new Date('2020-01-01T00:00:00Z'));
```

**4. Dismiss overlays** (best-effort; absent = fine):
```ts
await page.getByRole('button', { name: 'Accept All' }).click({ timeout: 4000 }).catch(() => {});
```

**5. Trigger lazy content so its bytes land in the archive.** This is the one "settle" that *is* yours —
not for pixel-stability (UI Verify handles that) but because content that never loaded was never
recorded. Scroll it into view before the snapshot:
```ts
await page.evaluate(async () => {
  for (let y = 0; y < document.body.scrollHeight; y += innerHeight) {
    scrollTo(0, y);
    await new Promise((r) => setTimeout(r, 60));
  }
  scrollTo(0, 0);
});
```

**6. Neutralize what can't be pinned** — there's no separate mask step; UI Verify diffs the
*archived DOM*, so hide the unstable element in the DOM before the snapshot and its varying
content never lands in the archive:
```ts
// target the container that reflows or reorders between runs
await page
  .locator('[data-testid="dynamic-region"]')
  .evaluateAll((els) => els.forEach((el) => (el.style.visibility = "hidden")));
```

**7. Freeze an app-driven JS animation** the capturer can't reach — an infinite charting-library loop, a `<canvas>` spinner with no final frame. Detect the capture *in the component* and render the end state. `@uiverify/playwright` sets a `UIVerify` user-agent marker and a `window.__UI_VERIFY__` global at record time, so a client-side branch works on its own; if the component decides this during **server-side rendering** (no `window` yet), also set a `UI_VERIFY` env var when you boot the app for the record run and check it:
```ts
// in the component (your app code, not the test):
const isUIVerify = () =>
  (typeof process !== 'undefined' && !!process.env.UI_VERIFY) ||            // SSR / build time
  (typeof window !== 'undefined' &&
    (navigator.userAgent.includes('UIVerify') || '__UI_VERIFY__' in window)); // browser

<Chart isAnimationActive={!isUIVerify()} />
```
Boot the app with the env var for the capture run only — e.g. `UI_VERIFY=1 npm start` — so a server-rendered branch can see it; the browser markers cover client-side animation without it. This is the record-side of the same freeze the Storybook/Vitest skills apply in-browser.

## Determinism the app itself owns (real-app cases a stub can't reach)

The recipes above pin variation from **outside** the app — routes, the clock, the DOM. The next five
live where a stub can't reach: **inside your components** (a branch on `isUIVerify()`, recipe 7's helper,
or the app's own CSS) or in **what the test waits for**. These are the ones that eat an afternoon if you
fight them from the test, especially under SSR.

**8. Infinite CSS animation lands on a random frame** — a rotating illustration, a pulsing dot. The
freeze is replay-side (see the mental model): the worker emulates `prefers-reduced-motion: reduce` and
re-runs the archived CSS, so the animation stops **only if the app honors that media query**. Add it to
the app's CSS — not the test:
```css
@media (prefers-reduced-motion: reduce) { .rotating-logo { animation: none } }
```
Use `animation: none`, **never `animation-duration: 0s`** — 0s leaves an infinite animation on its own
compositor layer and it sub-pixel-flakes (~1/100). No `isUIVerify()` needed here; the media query is the
whole lever. (**FAILED:** setting `reducedMotion` in the test/config is a **no-op at record time** — the
archive never bakes the computed transform, so there's nothing to freeze until replay. Don't reach for
it. Also: `reducedMotion` is not a top-level Playwright `use` option anyway — it lives under
`use: { contextOptions: { reducedMotion: 'reduce' } }` — but you don't need it at all.)

**9. A `<canvas>` / `requestAnimationFrame` animation diffs every run** — particles, a chart, an animated
background. rrweb bakes the canvas pixels (`rr_dataURL`) at the instant of capture, catching a different
frame each time. A media query can't reach a JS rAF loop, so branch in the component's effect:
```tsx
useEffect(() => {
  if (isUIVerify()) drawOneStaticFrame();   // one deterministic frame under capture
  else startRaf();                          // the live loop for real users
}, []);
```
**FAILED:** emulating `prefers-reduced-motion` in the test *does* set `matchMedia(...).matches = true` in
the page, but a hand-written rAF loop never reads it and keeps animating — the guard has to be in the JS.

**10. A random pick made *in render* changes the element each run** — a mascot/logo/hero image chosen by
`Math.random()`, a shuffled list. Not a pixel shift: a **different element**, a large whole-element diff,
every run. This is the biggest real-app time-sink. In any SSR framework (Next.js, Remix) the pick runs at
**server render time** and the archive bakes the SSR'd choice, so a browser-side fix can't touch it. Pin
the variant in the component and let real users keep the randomness:
```tsx
const src = isUIVerify() ? images[0] : images[Math.floor(Math.random() * images.length)];
```
Because the pick is server-side, **set `UI_VERIFY=1` on the app server for the capture run** (recipe 7)
so SSR and the client agree on the fixed variant — otherwise they disagree and React throws a hydration
mismatch. **FAILED (do not repeat):** seeding `Math.random` from a Playwright `addInitScript` fixture —
it patches the *browser* RNG, which cannot reach a pick React already made on the server; seeded captures
still rolled different sprites. (Redefining `navigator.userAgent` from an init script fails too — it's
why the marker is set at context creation, not in-page.)

**11. Even after gating the animation, a canvas/grid *layout* still differs** — the frame is static but
the square positions, particle seeds, or item order move run-to-run. The layout is drawing from the
**global** `Math.random`, and seeding it globally is **not enough**: React and other components consume
the shared sequence first, by an amount that varies with render timing, so your component gets different
values each capture. Give that component its **own reset-able RNG** (a tiny xo

Deterministic Playwright captures (archive-replay)

Mental model

@uiverify/playwright captures each test's final DOM + every resource the page loaded into an archive; UI Verify re-renders and pixel-diffs that archive server-side. So:

Whatever the page was at the instant of capture is baked into the archive forever. Your job is to drive the page to one canonical state before the snapshot. UI Verify can't un-see a random A/B variant, a live feed, or a piece of lazy content that never loaded.

- import { test, expect } from '@playwright/test';
+ import { test, expect } from '@uiverify/playwright';

The core skill: recognize the class, then pull the lever at record time

Everything below is the same move — something rendered differently run-to-run and it wasn't a real change; find what injected the variation and pin it before the snapshot.

Symptom in the diff	Cause class	Lever
Whole page reflows; height differs between runs	Feature flag / A-B experiment rendering a different variant per load (Optimizely, LaunchDarkly, VWO, your own)	Stub the flag calls so one fixed variant renders → recipe 1
A list / feed / counts differ	Live data from an API	Mock the endpoint with a fixed response → recipe 2
Timestamps, "today", a year, a chart's day axis drift	The clock (`Date.now`) at render time	Freeze `Date` before navigation → recipe 3
A banner / chat / consent overlay appears or shifts	Third-party widget injecting DOM	Stub or dismiss it → recipe 1 + 4
Blank/placeholder where an image should be	Lazy content that never loaded, so its bytes aren't in the archive	Trigger it at record time → recipe 5
Same content, packed or ordered differently each run	Dynamic layout that reflows or reorders on its own	Mask it (or pin a fixed order/size) → recipe 6
An infinite JS animation the capturer can't stop (a charting lib's loop, a `<canvas>` spinner)	App-driven animation with no final frame	Branch the component on capture and render the end state → recipe 7
A different logo/mascot/hero or list order each run — a whole-element diff, not a pixel shift	`Math.random()` in the render body, run at SSR time in Next.js/Remix	Pin the variant on `isUIVerify()` + `UI_VERIFY=1` on the app server → recipe 10
An infinite CSS keyframe animation on a different frame	CSS animation that ignores `prefers-reduced-motion`	Honor the media query in the app's CSS → recipe 8
A `<canvas>` (particles, chart, background) diffs every run	`requestAnimationFrame` loop the media query can't reach	Draw one static frame on `isUIVerify()` → recipe 9
The capture is a skeleton / spinner, not the loaded page	Snapshot fired before the data arrived	Wait for the real content (`networkidle`) → recipe 12

Prefer removing a whole class at the source: test a build/staging with flags and third-party scripts off and rows 1 and 4 disappear before you write any code.

Recipes

1. Stub feature-flag / third-party scripts (register in beforeEach, before goto):

await page.route(/optimizely|optly|launchdarkly|segment|intercom/i, (route) =>
  route.fulfill({ status: 204, body: '' }).catch(() => undefined),
);

2. Mock live data: intercept the API route and fulfill a fixed JSON fixture — same shape every run.

await page.route('**/api/items', (route) =>
  route.fulfill({ json: fixtures.items }),
);

3. Freeze the clock (before navigation — it changes what the app renders into the DOM). Use Playwright's built-in clock so Date, Date.now(), and Date()-without-new all stay correct:

await page.clock.setFixedTime(new Date('2020-01-01T00:00:00Z'));

4. Dismiss overlays (best-effort; absent = fine):

await page.getByRole('button', { name: 'Accept All' }).click({ timeout: 4000 }).catch(() => {});

await page.evaluate(async () => {
  for (let y = 0; y < document.body.scrollHeight; y += innerHeight) {
    scrollTo(0, y);
    await new Promise((r) => setTimeout(r, 60));
  }
  scrollTo(0, 0);
});

// target the container that reflows or reorders between runs
await page
  .locator('[data-testid="dynamic-region"]')
  .evaluateAll((els) => els.forEach((el) => (el.style.visibility = "hidden")));

// in the component (your app code, not the test):
const isUIVerify = () =>
  (typeof process !== 'undefined' && !!process.env.UI_VERIFY) ||            // SSR / build time
  (typeof window !== 'undefined' &&
    (navigator.userAgent.includes('UIVerify') || '__UI_VERIFY__' in window)); // browser

<Chart isAnimationActive={!isUIVerify()} />

Determinism the app itself owns (real-app cases a stub can't reach)

@media (prefers-reduced-motion: reduce) { .rotating-logo { animation: none } }

useEffect(() => {
  if (isUIVerify()) drawOneStaticFrame();   // one deterministic frame under capture
  else startRaf();                          // the live loop for real users
}, []);

const src = isUIVerify() ? images[0] : images[Math.floor(Math.random() * images.length)];

archive; UI Verify re-renders and pixel-diffs that archive server-side. So:

> Whatever the page **was at the instant of capture** is baked into the archive forever. Your job is to
> drive the page to one canonical state before the snapshot. UI Verify can't un-see a random A/B variant,
> a live feed, or a piece of lazy content that never loaded.

The snapshot fires automatically at the end of every test that passes or fails (a failed one too, so a broken
page shows up as a visual change rather than vanishing from the build; a test that times out is skipped), so your `beforeEach` + navigation *is* the
determinism surface. Integration is one import:

```diff
- import { test, expect } from '@playwright/test';
+ import { test, expect } from '@uiverify/playwright';
```

**What UI Verify handles server-side (don't hand-fix these):** it re-renders the archived DOM with
`prefers-reduced-motion` emulated and fonts and images settled. So pixel-level settling — waiting on
`document.fonts.ready`, sticky-header animation, image decode — is **not** your job. Your job is
narrower: make sure the **content and state** the archive records is the same every run.

One caveat on "animations": the freeze is **replay-side**, via reduced-motion emulation — the archive
does **not** bake a frozen frame. A CSS animation that honors `prefers-reduced-motion` freezes for free;
an **infinite** CSS/JS animation that ignores it keeps running on replay and lands on a random frame
(recipe 8), and a `<canvas>`/`requestAnimationFrame` loop is beyond the media query entirely (recipe 9).
Those live inside your app, so the fix does too.

## The core skill: recognize the class, then pull the lever at record time

Everything below is the same move — *something rendered differently run-to-run and it wasn't a real
change; find what injected the variation and pin it before the snapshot.*

| Symptom in the diff | Cause class | Lever |
|---|---|---|
| Whole page reflows; height differs between runs | **Feature flag / A-B experiment** rendering a different variant per load (Optimizely, LaunchDarkly, VWO, your own) | **Stub the flag calls** so one fixed variant renders → recipe 1 |
| A list / feed / counts differ | **Live data** from an API | **Mock the endpoint** with a fixed response → recipe 2 |
| Timestamps, "today", a year, a chart's day axis drift | **The clock** (`Date.now`) at render time | **Freeze `Date`** before navigation → recipe 3 |
| A banner / chat / consent overlay appears or shifts | **Third-party widget** injecting DOM | **Stub or dismiss** it → recipe 1 + 4 |
| Blank/placeholder where an image should be | **Lazy content** that never loaded, so its bytes aren't in the archive | **Trigger it at record time** → recipe 5 |
| Same content, packed or ordered differently each run | **Dynamic layout** that reflows or reorders on its own | **Mask** it (or pin a fixed order/size) → recipe 6 |
| An infinite JS animation the capturer can't stop (a charting lib's loop, a `<canvas>` spinner) | **App-driven animation** with no final frame | **Branch the component on capture** and render the end state → recipe 7 |
| A different logo/mascot/hero or list order each run — a whole-*element* diff, not a pixel shift | **`Math.random()` in the render body**, run at **SSR time** in Next.js/Remix | **Pin the variant on `isUIVerify()`** + `UI_VERIFY=1` on the app server → recipe 10 |
| An infinite CSS keyframe animation on a different frame | **CSS animation that ignores `prefers-reduced-motion`** | **Honor the media query in the app's CSS** → recipe 8 |
| A `<canvas>` (particles, chart, background) diffs every run | **`requestAnimationFrame` loop** the media query can't reach | **Draw one static frame on `isUIVerify()`** → recipe 9 |
| The capture is a skeleton / spinner, not the loaded page | **Snapshot fired before the data arrived** | **Wait for the real content** (`networkidle`) → recipe 12 |

Prefer removing a whole class at the source: **test a build/staging with flags and third-party scripts
off** and rows 1 and 4 disappear before you write any code.

## Recipes

**1. Stub feature-flag / third-party scripts** (register in `beforeEach`, before `goto`):
```ts
await page.route(/optimizely|optly|launchdarkly|segment|intercom/i, (route) =>
  route.fulfill({ status: 204, body: '' }).catch(() => undefined),
);
```
Use `fulfill({ status: 204 })`, **not `route.abort()`** — an aborted request reads as pending network
activity and can hang the page's readiness wait. A 204 completes it empty: the script "loads," resolves
no variant, and the page renders its control DOM. Identify the culprit by loading the page a few times
and watching `document.body.scrollHeight` flip between values.

**2. Mock live data:** intercept the API route and `fulfill` a fixed JSON fixture — same shape every run.
```ts
await page.route('**/api/items', (route) =>
  route.fulfill({ json: fixtures.items }),
);
```

**3. Freeze the clock** (before navigation — it changes what the app renders into the DOM). Use
Playwright's built-in clock so `Date`, `Date.now()`, and `Date()`-without-`new` all stay correct:
```ts
await page.clock.setFixedTime(new Date('2020-01-01T00:00:00Z'));
```

**4. Dismiss overlays** (best-effort; absent = fine):
```ts
await page.getByRole('button', { name: 'Accept All' }).click({ timeout: 4000 }).catch(() => {});
```

**5. Trigger lazy content so its bytes land in the archive.** This is the one "settle" that *is* yours —
not for pixel-stability (UI Verify handles that) but because content that never loaded was never
recorded. Scroll it into view before the snapshot:
```ts
await page.evaluate(async () => {
  for (let y = 0; y < document.body.scrollHeight; y += innerHeight) {
    scrollTo(0, y);
    await new Promise((r) => setTimeout(r, 60));
  }
  scrollTo(0, 0);
});
```

**6. Neutralize what can't be pinned** — there's no separate mask step; UI Verify diffs the
*archived DOM*, so hide the unstable element in the DOM before the snapshot and its varying
content never lands in the archive:
```ts
// target the container that reflows or reorders between runs
await page
  .locator('[data-testid="dynamic-region"]')
  .evaluateAll((els) => els.forEach((el) => (el.style.visibility = "hidden")));
```

**7. Freeze an app-driven JS animation** the capturer can't reach — an infinite charting-library loop, a `<canvas>` spinner with no final frame. Detect the capture *in the component* and render the end state. `@uiverify/playwright` sets a `UIVerify` user-agent marker and a `window.__UI_VERIFY__` global at record time, so a client-side branch works on its own; if the component decides this during **server-side rendering** (no `window` yet), also set a `UI_VERIFY` env var when you boot the app for the record run and check it:
```ts
// in the component (your app code, not the test):
const isUIVerify = () =>
  (typeof process !== 'undefined' && !!process.env.UI_VERIFY) ||            // SSR / build time
  (typeof window !== 'undefined' &&
    (navigator.userAgent.includes('UIVerify') || '__UI_VERIFY__' in window)); // browser

<Chart isAnimationActive={!isUIVerify()} />
```
Boot the app with the env var for the capture run only — e.g. `UI_VERIFY=1 npm start` — so a server-rendered branch can see it; the browser markers cover client-side animation without it. This is the record-side of the same freeze the Storybook/Vitest skills apply in-browser.

## Determinism the app itself owns (real-app cases a stub can't reach)

The recipes above pin variation from **outside** the app — routes, the clock, the DOM. The next five
live where a stub can't reach: **inside your components** (a branch on `isUIVerify()`, recipe 7's helper,
or the app's own CSS) or in **what the test waits for**. These are the ones that eat an afternoon if you
fight them from the test, especially under SSR.

**8. Infinite CSS animation lands on a random frame** — a rotating illustration, a pulsing dot. The
freeze is replay-side (see the mental model): the worker emulates `prefers-reduced-motion: reduce` and
re-runs the archived CSS, so the animation stops **only if the app honors that media query**. Add it to
the app's CSS — not the test:
```css
@media (prefers-reduced-motion: reduce) { .rotating-logo { animation: none } }
```
Use `animation: none`, **never `animation-duration: 0s`** — 0s leaves an infinite animation on its own
compositor layer and it sub-pixel-flakes (~1/100). No `isUIVerify()` needed here; the media query is the
whole lever. (**FAILED:** setting `reducedMotion` in the test/config is a **no-op at record time** — the
archive never bakes the computed transform, so there's nothing to freeze until replay. Don't reach for
it. Also: `reducedMotion` is not a top-level Playwright `use` option anyway — it lives under
`use: { contextOptions: { reducedMotion: 'reduce' } }` — but you don't need it at all.)

**9. A `<canvas>` / `requestAnimationFrame` animation diffs every run** — particles, a chart, an animated
background. rrweb bakes the canvas pixels (`rr_dataURL`) at the instant of capture, catching a different
frame each time. A media query can't reach a JS rAF loop, so branch in the component's effect:
```tsx
useEffect(() => {
  if (isUIVerify()) drawOneStaticFrame();   // one deterministic frame under capture
  else startRaf();                          // the live loop for real users
}, []);
```
**FAILED:** emulating `prefers-reduced-motion` in the test *does* set `matchMedia(...).matches = true` in
the page, but a hand-written rAF loop never reads it and keeps animating — the guard has to be in the JS.

**10. A random pick made *in render* changes the element each run** — a mascot/logo/hero image chosen by
`Math.random()`, a shuffled list. Not a pixel shift: a **different element**, a large whole-element diff,
every run. This is the biggest real-app time-sink. In any SSR framework (Next.js, Remix) the pick runs at
**server render time** and the archive bakes the SSR'd choice, so a browser-side fix can't touch it. Pin
the variant in the component and let real users keep the randomness:
```tsx
const src = isUIVerify() ? images[0] : images[Math.floor(Math.random() * images.length)];
```
Because the pick is server-side, **set `UI_VERIFY=1` on the app server for the capture run** (recipe 7)
so SSR and the client agree on the fixed variant — otherwise they disagree and React throws a hydration
mismatch. **FAILED (do not repeat):** seeding `Math.random` from a Playwright `addInitScript` fixture —
it patches the *browser* RNG, which cannot reach a pick React already made on the server; seeded captures
still rolled different sprites. (Redefining `navigator.userAgent` from an init script fails too — it's
why the marker is set at context creation, not in-page.)

**11. Even after gating the animation, a canvas/grid *layout* still differs** — the frame is static but
the square positions, particle seeds, or item order move run-to-run. The layout is drawing from the
**global** `Math.random`, and seeding it globally is **not enough**: React and other components consume
the shared sequence first, by an amount that varies with render timing, so your component gets different
values each capture. Give that component its **own reset-able RNG** (a tiny xo
