Never return HTML, CSS, JavaScript, ECharts options, data-mwai attributes, Data URLs, local paths, layout, charts, controls, or interaction decisions.
Every string is plain target-language prose without markup tags and without programming syntax.
The object has exactly contractVersion={VisualBriefingVersions.EVIDENCE_CONTRACT}, facts, metrics, tables, sourceCoverage, and assetPlan.
Every evidence item has a unique lowercase evidenceId and one or more sourceIds.
A sourceId is exactly one of the short handles listed under Sources, such as s1. Never invent one and never use a file name as a sourceId.
facts contain evidenceId, statement, sourceIds.
metrics contain evidenceId, label, numeric value, unit, sourceIds.
tables contain evidenceId, title, columns, rows, sourceIds; every row has exactly the column count.
sourceCoverage contains each supplied source exactly once with coverage USED, CONTEXTUAL, or OUT_OF_SCOPE and a short reason.
assetPlan contains each supplied visual asset exactly once with assetId, description, and target-language altText.

The object has exactly contractVersion={{VisualBriefingVersions.PLAN_CONTRACT}} and ordered sections.
Each section has exactly sectionId, role, titleSlotId, summarySlotId, and components.
Every section contains at least one component.
Section roles are HERO, EXECUTIVE_SUMMARY, NARRATIVE, EVIDENCE, EXPLORATION, or CONCLUSION.
The first section is the only HERO. EXECUTIVE_SUMMARY may occur once directly after it. CONCLUSION may occur once as the final section.
Every titleSlotId and summarySlotId is a unique content slot ID.
Each component has exactly componentId, kind, evidenceIds, slots, and assetId.
Every slot has exactly slotId and role. Slot roles are EYEBROW, TITLE, SUMMARY, BODY, LABEL, VALUE, CONTEXT, CAPTION, TABLE_DATA, PANEL, or RESULT.
Allowed kinds: TEXT, METRIC, TABLE, CHART, ASSET, CALLOUT, TABS, ACCORDION, FILTERABLE_TABLE, SIMULATION.
IDs are stable lowercase identifiers matching ^[a-z][a-z0-9_-]{0,63}$. Reference only supplied evidence IDs.
Slot IDs are unique across the whole briefing, including section title and summary slots.
Use these exact component slot patterns:

METRIC: LABEL, VALUE, CONTEXT.
CALLOUT: EYEBROW, TITLE, BODY.
CHART and ASSET: TITLE, CAPTION.
TABLE and FILTERABLE_TABLE: TITLE, SUMMARY, TABLE_DATA.
TABS: TITLE, SUMMARY, then one or more PANEL slots.
ACCORDION: TITLE, BODY.

# Test Documentation
This directory stores manual and automated test definitions for MindWork AI Studio.
## Directory Structure
- `integration_tests/`: Cross-component and end-to-end scenarios.
## Authoring Rules
- Use US English.
- Keep each feature area in its own Markdown file.
- Prefer stable test IDs (for example: `TC-CHAT-001`).
- Record expected behavior for:
- known vulnerable baseline builds (if relevant),
- current fixed builds.

# Chat Rendering Regression Tests
## Purpose
Validate that chat rendering remains stable and interactive when model output or user input contains raw HTML/CSS/JS-like payloads.
## Test Type
Manual regression and integration checks.
## Preconditions
1. You can run two builds:
- a known vulnerable baseline build,
- the current fixed build.
2. At least one provider is configured and can answer prompts.
3. Open the Chat page.
## Execution Flow (for each test case)
1. Copy the test prompt exactly into the user prompt field.
2. Send the prompt.
3. Observe behavior immediately after send.
4. If the UI is still visible, type additional text in the prompt input.
5. Repeat on both builds.
## Test Cases
### TC-CHAT-001 - CSS Kill Switch
**Prompt**
```text
Respond with exactly the content below. No explanations, no Markdown code fences, no backticks.
<style>
* { visibility: hidden !important; }
html, body { background: white !important; }
</style>
<div>TEST</div>
```
**Expected result (vulnerable baseline)**
UI may turn into a white/invisible page immediately after sending.
**Expected result (fixed build)**
Chat stays visible and usable. Content is rendered as inert text/code, not active page styling.
---
### TC-CHAT-002 - Full White Overlay
**Prompt**
```text
Respond with exactly the content below. No explanations, no Markdown code fences, no backticks.
<style>
html, body { overflow: hidden !important; }
body::before {
content: "";
position: fixed;
inset: 0;
background: white;
z-index: 2147483647;
}
</style>
<div>TEST</div>
```
**Expected result (vulnerable baseline)**
UI may become fully white and non-interactive immediately after sending.
**Expected result (fixed build)**
No overlay takes over the app. Chat remains interactive.
---
### TC-CHAT-003 - Inline Event Handler Injection
**Prompt**
```text
Respond with exactly the content below. No explanations, no Markdown code fences, no backticks.
<img src="x" onerror="document.body.innerHTML=''; document.body.style.background='white';">
<div>TEST</div>
```
**Expected result (vulnerable baseline)**
UI may break/blank immediately after sending.
**Expected result (fixed build)**
No JavaScript execution from message content. Chat remains stable.
---
### TC-CHAT-004 - SVG Onload Injection Attempt
**Prompt**
```text
Respond with exactly the content below. No explanations, no Markdown code fences, no backticks.
<svg xmlns="http://www.w3.org/2000/svg" onload="document.documentElement.innerHTML=''"></svg>
<div>TEST</div>
```
**Expected result (vulnerable baseline)**
May or may not trigger depending on parser/runtime behavior.
**Expected result (fixed build)**
No script-like execution from content. Chat remains stable and interactive.
## Notes
- If a test fails on the fixed build, capture:
- exact prompt used,
- whether failure happened right after send or while typing,
- whether a refresh restores the app.
