## II. WEB DEVELOPMENT PHILOSOPHY (2025 Best Practices)

### Core Principles
1. **Component-first architecture** - Everything is a reusable component
2. **AI-friendly markup** - Semantic HTML, clear structure, accessible
3. **Performance by default** - Ship minimal JS, optimize for Core Web Vitals
4. **Epistemic transparency** - Track what you know about design decisions
5. **ReAct pattern** - Reason → Act → Observe → Iterate

### Technology Stack (Recommended)

**Static Sites & Docs:**
- ✅ **Astro** (RECOMMENDED) - Zero JS by default, markdown-first, component islands
- ✅ **Docusaurus** - Best for technical documentation, API reference
- ⚠️ Next.js - Use for dynamic apps, not static marketing sites

**Styling:**
- ✅ **Tailwind CSS** - Utility-first, AI-friendly class names
- ✅ **CSS Variables** - Semantic theming (e.g., `--color-primary`)

**Components:**
- ✅ **React/Preact** - For interactive islands
- ✅ **Web Components** - For framework-agnostic reusability

**Why NOT Jinja2?**
- ❌ No component encapsulation
- ❌ No reactivity/state management
- ❌ Python-only, not AI-friendly for modern workflows
- ✅ Use Astro or React instead for component-based architecture

## III. EMPIRICA CASCADE FOR WEB PROJECTS

### Standard Web Workflow

```
BOOTSTRAP → PREFLIGHT → [INVESTIGATE → CHECK]* → ACT → POSTFLIGHT
```

**Note:** `[INVESTIGATE → CHECK]*` means zero or more investigation cycles before proceeding to ACT.

### PREFLIGHT (Before Starting Web Work)

**Task-specific vectors to assess:**

```python
# Create session first using CLI or MCP
# CLI: empirica session-create --ai-id claude-web
# MCP: create_session(ai_id="claude-web")

# Execute PREFLIGHT
execute_preflight(
    session_id=session_id,
    prompt="Build Empirica documentation website with Astro"
)

# Assess your knowledge HONESTLY
submit_preflight_assessment(
    session_id=session_id,
    vectors={
        "engagement": 0.9,      # Are you engaged?
        "know": 0.X,            # Do you KNOW Astro/React/Tailwind?
        "do": 0.X,              # Can you EXECUTE component design?
        "context": 0.X,         # Do you understand the brand/users?
        "clarity": 0.X,         # Is the design spec clear?
        "coherence": 0.X,       # Does the architecture make sense?
        "signal": 0.X,          # Quality of design requirements
        "density": 0.X,         # Information overload?
        "state": 0.X,           # Current project state awareness
        "change": 0.X,          # Can you track design iterations?
        "completion": 0.0,      # Starting point
        "impact": 0.X,          # Awareness of UX consequences
        "uncertainty": 0.X      # What DON'T you know? (HIGH = investigate!)
    },
    reasoning="Web context: Know React 0.8, Astro 0.4 (need investigation), design patterns 0.7"
)
```

**Web-specific uncertainty triggers:**
- Uncertainty ≥0.6 in KNOW → Investigate framework/library docs
- Uncertainty ≥0.5 in CONTEXT → Research target users, brand guidelines
- Uncertainty ≥0.5 in DO → Build proof-of-concept components

---

### INVESTIGATE (Web-Specific Patterns)

**Investigation goals for web projects:**

```python
# Example: Investigating Astro component patterns
create_goal(
    session_id=session_id,
    objective="Research Astro component islands and content collections",
    scope={
        "breadth": 0.3,       # Focused: one framework
        "duration": 0.2,      # Short: 30-60 minutes
        "coordination": 0.1   # Solo work
    },
    success_criteria=[
        "Understand Astro islands architecture",
        "Know how to integrate React components",
        "Can build content collections for docs"
    ]
)

# Add subtasks
add_subtask(
    goal_id=goal_id,
    description="Read Astro docs on islands architecture",
    importance="critical"
)

add_subtask(
    goal_id=goal_id,
    description="Review Astro + React integration examples on GitHub",
    importance="high"
)

add_subtask(
    goal_id=goal_id,
    description="Build proof-of-concept component with partial hydration",
    importance="high"
)
```

**Web investigation sources:**
- ✅ Official framework docs (Astro, React, Tailwind)
- ✅ GitHub repositories (search for component patterns)
- ✅ patterns.dev (React patterns, AI UI patterns)
- ✅ MDN Web Docs (web standards)
- ✅ Can I Use (browser compatibility)

---

### CHECK (Web Project Gates)

**Web-specific readiness criteria:**

```python
execute_check(
    session_id=session_id,
    findings=[
        "Astro uses islands architecture - components hydrate independently",
        "Can integrate React/Preact/Vue in same project",
        "Content collections provide type-safe markdown handling",
        "Tailwind config supports Empirica brand colors"
    ],
    remaining_unknowns=[
        "How to optimize build time for large docs sites",
        "Best practices for SEO meta tags in Astro",
        "Accessibility testing workflow"
    ],
    confidence_to_proceed=0.75  # Ready to start implementation
)

submit_check_assessment(
    session_id=session_id,
    vectors={...},  # Updated vectors post-investigation
    decision="proceed",  # or "investigate" if confidence < 0.7
    reasoning="Know Astro basics, can build components, understand brand. Ready to implement."
)
```

**Decision logic:**
- Confidence ≥ 0.75 AND unknowns ≤ 3 → Proceed to ACT
- Confidence < 0.7 OR unknowns > 5 → Loop back to INVESTIGATE
- Design/UX uncertainty > 0.6 → Create mockups/wireframes first

---

### ACT (Web Implementation)

**Web-specific actions:**

1. **Setup Project Structure**
   ```bash
   # Astro project (recommended)
   npm create astro@latest empirica-docs
   cd empirica-docs
   npm install @astrojs/react @astrojs/tailwind
   ```

2. **Create Component Architecture**
   ```
   src/
   ├── components/
   │   ├── layout/
   │   │   ├── Header.astro
   │   │   ├── Footer.astro
   │   │   └── Navigation.astro
   │   ├── ui/
   │   │   ├── Button.tsx (React island)
   │   │   ├── Card.astro
   │   │   └── CodeBlock.astro
   │   └── docs/
   │       ├── TOC.astro
   │       ├── SearchBar.tsx
   │       └── Breadcrumb.astro
   ├── content/
   │   ├── docs/
   │   │   └── [markdown files]
   │   └── config.ts (type-safe content)
   ├── layouts/
   │   ├── BaseLayout.astro
   │   └── DocsLayout.astro
   └── pages/
       ├── index.astro
       └── docs/
           └── [...slug].astro
   ```

3. **Design System (Tailwind + CSS Variables)**
   ```css
   /* theme.css */
   :root {
     --color-primary: #6366f1;       /* Indigo-500 */
     --color-secondary: #0ea5e9;     /* Sky-500 */
     --color-bg-dark: #0f172a;       /* Slate-900 */
     --color-text: #e2e8f0;          /* Slate-200 */
     --font-body: 'Inter', sans-serif;
     --font-mono: 'JetBrains Mono', monospace;
   }
   ```

4. **AI-Friendly Component Patterns**
   ```astro
   ---
   // Card.astro - Semantic, accessible, reusable
   interface Props {
     title: string;
     description?: string;
     href?: string;
     icon?: string;
   }
   
   const { title, description, href, icon } = Astro.props;
   ---
   
   <article class="card" role="article" aria-labelledby={`card-${title}`}>
     {icon && <span class="card-icon" aria-hidden="true">{icon}</span>}
     <h3 id={`card-${title}`}>{title}</h3>
     {description && <p>{description}</p>}
     {href && <a href={href} aria-label={`Learn more about ${title}`}>Learn more →</a>}
   </article>
   
   <style>
     .card {
       @apply bg-slate-800/70 rounded-lg p-6 hover:bg-slate-700/70 transition;
     }
   </style>
   ```

5. **Save Checkpoints During Long Work**
   ```python
   # Every 30-60 minutes or at milestones
   create_git_checkpoint(
       session_id=session_id,
       phase="ACT",
       round_num=1,  # Increment each checkpoint
       vectors=current_vectors,
       metadata={
           "progress": "Component library 60% complete",
           "milestone": "Header/Footer/Navigation done",
           "next": "Build docs page templates"
       }
   )
   ```

---

### POSTFLIGHT (After Completing Web Work)

**Measure your web development learning:**

```python
execute_postflight(
    session_id=session_id,
    task_summary="Built Empirica documentation site with Astro, React islands, Tailwind"
)

submit_postflight_assessment(
    session_id=session_id,
    vectors={
        "engagement": 0.9,
        "know": 0.8,        # Learned Astro patterns (+0.4 from PREFLIGHT)
        "do": 0.85,         # Built component library (+0.3)
        "context": 0.9,     # Deep understanding of Empirica brand (+0.3)
        "clarity": 0.95,    # Clear final design
        "coherence": 0.9,   # Consistent architecture
        "signal": 0.85,
        "density": 0.7,
        "state": 0.9,       # Know project state thoroughly
        "change": 0.85,     # Tracked iterations well
        "completion": 1.0,  # Task complete!
        "impact": 0.9,      # Aware of UX improvements
        "uncertainty": 0.2  # Low uncertainty (-0.5 from PREFLIGHT)
    },
    reasoning="Learned Astro islands (+0.4 KNOW), built 20+ components (+0.3 DO), shipped 15-page docs site. Uncertainty reduced from 0.7 to 0.2."
)

# Get calibration report
calibration = get_calibration_report(session_id=session_id)
print(f"Calibration: {calibration['calibration']}")  # well_calibrated?
```

**Web-specific learning metrics:**
- KNOW delta: Did you learn the framework/library?
- DO delta: Can you build components independently now?
- UNCERTAINTY delta: Did investigation reduce unknowns?
- IMPACT: Did you improve UX measurably?

## IV. WEB-SPECIFIC BEST PRACTICES

### A. Component Design Patterns (2025)

**1. Functional Components + Hooks (React/Preact)**
```tsx
// Button.tsx - React island in Astro
import { useState } from 'react';

interface ButtonProps {
  variant?: 'primary' | 'secondary';
  onClick?: () => void;
  children: React.ReactNode;
}

export function Button({ variant = 'primary', onClick, children }: ButtonProps) {
  const [loading, setLoading] = useState(false);
  
  return (
    <button
      className={`btn btn-${variant}`}
      onClick={onClick}
      disabled={loading}
      aria-busy={loading}
    >
      {children}
    </button>
  );
}
```

**2. Astro Components (Server-rendered, Zero JS)**
```astro
---
// Card.astro - Pure static, no JS
interface Props {
  title: string;
  href?: string;
}

const { title, href } = Astro.props;
---

<article class="card">
  <h3>{title}</h3>
  {href && <a href={href}>Learn more →</a>}
</article>

<style>
  .card { /* scoped styles */ }
</style>
```

**3. Islands Architecture (Partial Hydration)**
```astro
---
// DocsPage.astro
import Header from '@/components/Header.astro';  // Static
import SearchBar from '@/components/SearchBar.tsx';  // Interactive island
import Footer from '@/components/Footer.astro';  // Static
---

<Header />
<!-- Only SearchBar hydrates on client, rest is static HTML -->
<SearchBar client:load />  
<main>
  <slot />
</main>
<Footer />
```

---

### B. UI/UX Best Practices (AI-Friendly)

**1. Agentic UX Principles**
- **Proactive communication** - Show status, progress, errors clearly
- **Transparent reasoning** - Explain AI decisions in UI
- **Adaptive control** - Let users override AI suggestions
- **Mental models** - Match user expectations for AI behavior

**2. Accessibility (A11y) Requirements**
```astro
<!-- Semantic HTML -->
<nav aria-label="Main navigation">
  <ul role="list">
    <li><a href="/" aria-current="page">Home</a></li>
  </ul>
</nav>

<!-- ARIA labels for dynamic content -->
<div role="status" aria-live="polite" aria-atomic="true">
  {aiResponse && <p>{aiResponse}</p>}
</div>

<!-- Keyboard navigation -->
<button aria-label="Open search" data-shortcut="Ctrl+K">
  Search
</button>
```

**3. Performance Optimization**
```astro
---
// Lazy-load images
import { Image } from 'astro:assets';
import heroImage from '@/assets/hero.png';
---

<Image
  src={heroImage}
  alt="Empirica SDK"
  width={1200}
  height={600}
  loading="lazy"
  decoding="async"
/>

<!-- Preload critical resources -->
<link rel="preload" href="/fonts/inter.woff2" as="font" type="font/woff2" crossorigin />
```

**4. ReAct Pattern for AI Components**
```tsx
// AIChat.tsx - Streaming responses
import { useState } from 'react';

export function AIChat() {
  const [messages, setMessages] = useState([]);
  const [thinking, setThinking] = useState(false);
  
  async function handleSubmit(prompt: string) {
    setThinking(true);  // Reasoning phase
    
    // Act: Call AI endpoint
    const response = await fetch('/api/chat', {
      method: 'POST',
      body: JSON.stringify({ prompt })
    });
    
    // Observe: Stream response
    const reader = response.body.getReader();
    let accumulated = '';
    
    while (true) {
      const { done, value } = await reader.read();
      if (done) break;
      
      accumulated += new TextDecoder().decode(value);
      setMessages(prev => [...prev, { role: 'assistant', content: accumulated }]);
    }
    
    setThinking(false);  // Iteration complete
  }
  
  return (
    <div className="chat" role="log" aria-live="polite">
      {messages.map((msg, i) => (
        <div key={i} className={`message message-${msg.role}`}>
          {msg.content}
        </div>
      ))}
      {thinking && <div className="thinking" aria-label="AI is thinking">●●●</div>}
    </div>
  );
}
```

---

### C. Technology Decision Matrix

**When to use what:**

| Use Case | Framework | Why |
|----------|-----------|-----|
| Documentation site | Astro + Docusaurus | Fast, markdown-first, versioning |
| Marketing/landing page | Astro | Zero JS, perfect Lighthouse scores |
| Blog | Astro | Content collections, RSS, SEO |
| Web app (dashboard) | Next.js + React | SSR, API routes, dynamic |
| Interactive tools | React + Vite | Fast dev, SPA, rich state |
| Design system docs | Astro + Storybook | Component showcase, static |

**Empirica website stack (recommended):**
- **Framework:** Astro 4.x
- **Styling:** Tailwind CSS 3.x
- **Islands:** React 18+ (for interactive components only)
- **Content:** Markdown + Content Collections (type-safe)
- **Deployment:** Cloudflare Pages / Vercel / Netlify

---

## V. MCP TOOLS FOR WEB DEVELOPMENT

### Standard Empirica Tools (Same as Core)

**Session:**
- `create_session(ai_id)` - Start session (CLI: `empirica session-create`)
- `get_epistemic_state(session_id)` - Check your knowledge

**CASCADE:**
- `execute_preflight(session_id, prompt)` - Assess before work
- `submit_preflight_assessment(session_id, vectors, reasoning)` - Submit baseline
- `execute_check(session_id, findings, unknowns, confidence)` - Gate decision
- `submit_check_assessment(session_id, vectors, decision, reasoning)` - Proceed or investigate?
- `execute_postflight(session_id, task_summary)` - Measure learning
- `submit_postflight_assessment(session_id, vectors, reasoning)` - Final calibration

**Goals:**
- `create_goal(session_id, objective, scope)` - Investigation goals
- `add_subtask(goal_id, description, importance)` - Break down work
- `complete_subtask(task_id, evidence)` - Mark done

**Continuity:**
- `create_git_checkpoint(session_id, phase, round_num, vectors, metadata)` - Save progress
- `load_git_checkpoint(session_id)` - Resume work
- `create_handoff_report(...)` - Handoff to next AI
- `query_handoff_reports(ai_id, limit)` - Load previous work

**Edit Guard (File Editing):**
- `edit_with_confidence(file_path, old_str, new_str, context_source, session_id)` - Metacognitive editing

### Web-Specific Tool Usage

**Example: Building component library**
```python
# 1. Create Session
# CLI: empirica session-create --ai-id claude-web
# MCP: create_session(ai_id="claude-web")

# 2. PREFLIGHT
execute_preflight(session_id, prompt="Build Empirica component library in Astro")
submit_preflight_assessment(session_id, vectors={...}, reasoning="...")

# 3. INVESTIGATE (if uncertainty high)
goal = create_goal(
    session_id=session_id,
    objective="Research Astro component patterns and React integration",
    scope={"breadth": 0.3, "duration": 0.2, "coordination": 0.1}
)

# 4. CHECK
execute_check(
    session_id=session_id,
    findings=["Astro supports React islands", "Can use Tailwind", ...],
    unknowns=["Build optimization", "Accessibility testing"],
    confidence_to_proceed=0.8
)
submit_check_assessment(session_id, vectors={...}, decision="proceed")

# 5. ACT (build components)
# ... use edit_with_confidence for file edits ...

# 6. POSTFLIGHT
execute_postflight(session_id, task_summary="Built 20+ Astro components")
submit_postflight_assessment(session_id, vectors={...}, reasoning="...")

# 7. HANDOFF (if switching AI models)
create_handoff_report(
    session_id=session_id,
    task_summary="Component library complete, need UX review",
    key_findings=["Astro islands work well", "Tailwind config stable"],
    next_session_context="Gemini: please review UX and suggest improvements",
    artifacts_created=["src/components/**/*.astro", "tailwind.config.js"]
)
```

---

## VI. MULTI-AI COLLABORATION (Antigravity Pattern)

**Antigravity uses 3 AI models - leverage their strengths:**

### Claude (Architecture & Implementation)
- **Strengths:** Complex logic, architecture design, TypeScript
- **Use for:** Component structure, build configuration, advanced patterns
- **AI_ID:** `claude-web`

### Gemini (Design & UX)
- **Strengths:** Visual design, user experience, creative layouts
- **Use for:** UI mockups, color schemes, accessibility review
- **AI_ID:** `gemini-web`

### GPT (Implementation & Iteration)
- **Strengths:** Fast iteration, bug fixes, documentation
- **Use for:** Component refinement, content writing, testing
- **AI_ID:** `gpt-web`

### Handoff Pattern

```python
# Claude builds architecture
# CLI: claude_session=$(empirica session-create --ai-id claude-web --quiet)
# MCP: claude_session = create_session(ai_id="claude-web")
# ... Claude does PREFLIGHT → ACT → POSTFLIGHT ...
create_handoff_report(
    session_id=claude_session,
    task_summary="Component architecture complete",
    next_session_context="Gemini: Review UX, suggest visual improvements"
)

# Gemini takes over for UX review
# gemini_session = create_session(ai_id="gemini-web")
handoffs = query_handoff_reports(ai_id="claude-web", limit=1)
# ... Gemini does UX improvements ...
create_handoff_report(
    session_id=gemini_session,
    task_summary="UX improvements applied",
    next_session_context="GPT: Polish components, write docs"
)

# GPT finalizes
# gpt_session = create_session(ai_id="gpt-web")
# ... GPT polishes and documents ...
```

---

## VII. COMMON WEB TASKS (Decision Trees)

### Task: Build Documentation Site

**PREFLIGHT Assessment:**
- Know Astro? → High (0.7+) = Proceed | Low (<0.5) = Investigate
- Know content structure? → High = Proceed | Low = Research users/docs
- Design clarity? → High = Build | Low = Create wireframes

**INVESTIGATE (if needed):**
1. Research Astro docs
2. Review example docs sites (Astro docs, Next.js docs)
3. Study Docusaurus patterns
4. Check target audience needs

**CHECK Decision:**
- Confidence ≥ 0.75 + clarity on structure → ACT
- Confidence < 0.7 → Loop to INVESTIGATE

**ACT:**
1. Initialize Astro project
2. Setup content collections
3. Build layout components (Header, Footer, Navigation, TOC)
4. Create page templates
5. Style with Tailwind
6. Add search (Algolia or Pagefind)
7. Deploy

**POSTFLIGHT:**
- Measure: Did KNOW increase? Can you build docs sites now?
- Calibrate: Was initial confidence accurate?

---

### Task: Build Interactive Dashboard

**PREFLIGHT Assessment:**
- Know React/Next.js? → High = Proceed | Low = Investigate
- Understand data flow? → High = Proceed | Low = Research API
- UX requirements clear? → High = Build | Low = Create mockups

**Framework Decision:**
- Static dashboard (no backend) → React + Vite
- Dynamic (SSR, API routes) → Next.js
- Real-time updates → Next.js + WebSockets

**INVESTIGATE (if needed):**
1. Research state management (Zustand, Redux)
2. Study dashboard UI patterns (ShadCN, Tremor)
3. Review data visualization libraries (Recharts, Chart.js)
4. Plan component hierarchy

**CHECK Decision:**
- Architecture clear + confidence ≥ 0.75 → ACT
- Unknowns > 3 → Loop to INVESTIGATE

**ACT:**
1. Initialize project (Vite or Next.js)
2. Setup state management
3. Build layout shell
4. Create data fetching hooks
5. Build visualization components
6. Add interactivity
7. Test and deploy

---

## VIII. EMPIRICA WEB PHILOSOPHY

### Core Values

**1. Component-First Thinking**
- Every UI element is a component
- Components are reusable, composable, testable
- State is local, props flow down

**2. Performance by Default**
- Ship zero JS unless needed (Astro islands)
- Optimize images, fonts, CSS
- Measure Core Web Vitals (LCP < 2.5s, CLS < 0.1, FID < 100ms)

**3. Accessibility Always**
- Semantic HTML first
- ARIA labels for dynamic content
- Keyboard navigation
- Screen reader testing

**4. AI-Friendly Markup**
- Clear structure, consistent patterns
- Semantic class names
- Type-safe props (TypeScript)
- Documented component APIs

**5. Epistemic Humility**
- **Know what you don't know** about frameworks
- **Investigate before building** complex features
- **Track your learning** (PREFLIGHT → POSTFLIGHT deltas)
- **Admit uncertainty** when design is unclear

---

## IX. WHEN TO USE EMPIRICA FOR WEB WORK

### Always Use CASCADE For:
- ✅ **Full website builds** (>1 hour of work)
- ✅ **Component library creation** (new design systems)
- ✅ **Framework migrations** (Jinja2 → Astro, etc.)
- ✅ **Complex UI/UX features** (dashboards, interactive tools)
- ✅ **Documentation sites** (multi-page, versioned docs)

### Optional For:
- ⚠️ **Single component tweaks** (<10 min, trivial changes)
- ⚠️ **CSS adjustments** (color changes, spacing)
- ⚠️ **Content updates** (markdown edits, text changes)

### Uncertainty Types - Critical Distinction:

**Procedural Uncertainty**: "I don't know HOW to build this component"  
**Domain Uncertainty**: "I don't know WHAT design patterns will work best"

→ **If EITHER is >0.5, use Empirica CASCADE**  
→ **Don't confuse framework knowledge with design certainty**

**Example:**
- "Build documentation site with Astro" → **USE CASCADE**
  - Procedural: 0.3 (know how to use Astro basics)
  - Domain: 0.7 (don't know what content structure/navigation works best)
  - → Domain uncertainty is high, use CASCADE

- "Change button color to blue" → **SKIP CASCADE**
  - Procedural: 0.1 (trivial CSS change)

### Key Principle:
**If the web work matters, use Empirica.** It takes 5 seconds to bootstrap and saves hours debugging bad architectural decisions.

## X. QUICK REFERENCE COMMANDS

### Session Management
```bash
# CLI
empirica session-create --ai-id claude-web
empirica sessions-list
empirica checkpoint-create --session-id <ID> --phase "ACT" --round 1

# MCP (Python)
session = create_session(ai_id="claude-web")
checkpoint = load_git_checkpoint("latest:active:claude-web")
```

### Web-Specific Patterns
```bash
# Initialize Astro project
npm create astro@latest my-site
cd my-site
npm install @astrojs/react @astrojs/tailwind

# Build
npm run build

# Dev server
npm run dev
```

## XI. INTEGRATION WITH EXISTING EMPIRICA WEBSITE

**Current state:**
- Uses Jinja2 templates (Python)
- Location: `/home/yogapad/empirical-ai/empirica/website/`
- Builder: `website/builder/generate_site_v2.py`

**Recommended migration:**
1. **PREFLIGHT:** Assess knowledge of current website structure
2. **INVESTIGATE:** Research Astro migration patterns, audit existing content
3. **CHECK:** Confidence ≥ 0.75 to proceed with migration?
4. **ACT:** Migrate templates to Astro components incrementally
5. **POSTFLIGHT:** Measure learning, document migration process

**Migration path:**
- Jinja2 `base.html` → Astro `BaseLayout.astro`
- Jinja2 partials → Astro components (`Header.astro`, `Footer.astro`)
- Python generator → Astro content collections
- Deploy: Cloudflare Pages (faster than current setup)

## XII. EXAMPLES

### Example 1: Building a Card Component

**PREFLIGHT:**
```python
# session = create_session(ai_id="claude-web")
execute_preflight(session_id, prompt="Build reusable Card component in Astro")
submit_preflight_assessment(
    session_id=session_id,
    vectors={"know": 0.7, "do": 0.8, "uncertainty": 0.3},
    reasoning="Know Astro basics, high confidence"
)
```

**ACT:**
```astro
---
// Card.astro
interface Props {
  title: string;
  description?: string;
  href?: string;
  variant?: 'default' | 'highlighted';
}

const { title, description, href, variant = 'default' } = Astro.props;
---

<article class={`card card-${variant}`} role="article">
  <h3>{title}</h3>
  {description && <p>{description}</p>}
  {href && (
    <a href={href} class="card-link">
      Learn more →
    </a>
  )}
</article>

<style>
  .card {
    @apply bg-slate-800/70 rounded-lg p-6 transition;
  }
  
  .card-highlighted {
    @apply border-2 border-indigo-500;
  }
  
  .card-link {
    @apply text-indigo-400 hover:text-indigo-300;
  }
</style>
```

**POSTFLIGHT:**
```python
submit_postflight_assessment(
    session_id=session_id,
    vectors={"know": 0.9, "do": 0.9, "uncertainty": 0.1},
    reasoning="Built reusable Card component (+0.2 KNOW, +0.1 DO). Learned Astro style scoping."
)
```

---

### Example 2: Interactive Search Component

**PREFLIGHT:**
```python
execute_preflight(session_id, prompt="Build client-side search with React in Astro")
submit_preflight_assessment(
    vectors={"know": 0.6, "do": 0.7, "uncertainty": 0.5},  # Higher uncertainty!
    reasoning="Know React, unsure about Astro islands integration"
)
```

**INVESTIGATE:**
```python
create_goal(
    session_id=session_id,
    objective="Research Astro client directives and React integration",
    scope={"breadth": 0.2, "duration": 0.2, "coordination": 0.0}
)

add_subtask(goal_id, "Read Astro islands docs", "critical")
add_subtask(goal_id, "Test client:load vs client:visible", "high")
```

**CHECK:**
```python
execute_check(
    session_id=session_id,
    findings=[
        "client:load hydrates immediately",
        "client:visible hydrates when visible",
        "Can pass props from Astro to React"
    ],
    unknowns=["Performance impact", "SEO implications"],
    confidence_to_proceed=0.8
)
```

**ACT:**
```tsx
// SearchBar.tsx
import { useState } from 'react';

interface SearchBarProps {
  placeholder?: string;
}

export function SearchBar({ placeholder = 'Search...' }: SearchBarProps) {
  const [query, setQuery] = useState('');
  
  return (
    <div className="search-bar" role="search">
      <input
        type="search"
        value={query}
        onChange={(e) => setQuery(e.target.value)}
        placeholder={placeholder}
        aria-label="Search documentation"
      />
    </div>
  );
}
```

```astro
---
// DocsLayout.astro
import SearchBar from '@/components/SearchBar.tsx';
---

<header>
  <SearchBar client:load placeholder="Search docs..." />
</header>
```

**POSTFLIGHT:**
```python
submit_postflight_assessment(
    vectors={"know": 0.85, "do": 0.9, "uncertainty": 0.2},
    reasoning="Learned Astro islands (+0.25 KNOW). Can integrate React now (+0.2 DO)."
)
```

## XIV. NEXT STEPS

1. **Bootstrap your session:** `empirica session-create --ai-id <model>-web`
2. **Run PREFLIGHT:** Assess your web development knowledge
3. **Investigate gaps:** Use goal management to research unknowns
4. **CHECK readiness:** Are you confident to build?
5. **Build incrementally:** Use checkpoints to save progress
6. **Run POSTFLIGHT:** Measure your learning

**Remember:** Empirica is not overhead. It's systematic tracking that makes you better at web development over time.
