# Sprint 9.5: Critical UX Fixes

**Status**: ✅ COMPLETE (100% - All 5 features delivered)
**Duration**: 3 days (21 hours total)
**Goal**: Fix critical UX blockers preventing new user onboarding and core workflow completion
**Completed**: 2025-11-20
**Progress**: Features 1-5 ✅ All Completed (PRs #23, #24, #25, #26, #28)

---

## Overview

Sprint 9.5 addresses **five showstopper UX gaps** identified in the comprehensive UX audit conducted on 2025-11-15. These gaps make CodeFRAME unusable for new users despite having robust backend functionality (87% test coverage, 450+ tests passing).

**Context**: UX analysis revealed a 3-point maturity gap between backend (8/10) and frontend (5/10), with 5 critical blockers preventing basic workflows:
1. Users cannot start the dashboard (no `serve` command)
2. Users cannot create projects via UI (dashboard assumes project exists)
3. Users cannot answer discovery questions (UI shows questions but no input)
4. Users cannot see context management (ContextPanel exists but hidden)
5. Users lose context between sessions (no session lifecycle management)

**Why Sprint 9.5?**: These issues must be fixed BEFORE Sprint 10 E2E testing. You cannot write E2E tests for workflows that don't exist or are broken. This 2.5-day sprint closes the gap between backend and frontend, bringing Technical User readiness from 50% to 70%.

## Features

### Feature 1: Server Start Command ⚡ QUICK WIN ✅ COMPLETED

**Status**: ✅ Merged (PR #23 - 2025-11-19)
**Effort**: 2 hours (Actual: ~2.5 hours)
**Priority**: P0 - Unblocks dashboard access
**Issue**: Users don't know how to start the dashboard after `codeframe init`

#### Problem Statement

**Current Behavior**:
```bash
$ codeframe init my-app
✓ Initialized project: my-app
  Location: /home/user/my-app
Next steps:
  1. codeframe start  - Start project execution
  2. codeframe status - Check project status

$ codeframe start
🚀 Starting project my-app...
# Nothing happens - no server starts, no agents run
# User is stuck
```

**Expected Behavior**:
```bash
$ codeframe serve
🌐 Starting dashboard server...
✓ Dashboard available at http://localhost:8080
✓ WebSocket server running
✓ Press Ctrl+C to stop

# Optionally auto-opens browser
```

#### Scope

**Add `serve` Command to CLI**
- Location: `codeframe/cli.py`
- Starts FastAPI application with uvicorn
- Default port: 8080 (configurable via `--port`)
- Option to auto-open browser (`--open-browser` flag)
- Graceful shutdown on Ctrl+C

**Command Signature**:
```python
@app.command()
def serve(
    port: int = typer.Option(8080, "--port", "-p", help="Port to run server on"),
    host: str = typer.Option("0.0.0.0", "--host", help="Host to bind to"),
    open_browser: bool = typer.Option(True, "--open-browser/--no-browser", help="Auto-open browser"),
    reload: bool = typer.Option(False, "--reload", help="Enable auto-reload (dev mode)"),
):
    """Start the CodeFRAME dashboard server."""
```

**Implementation Details**:

1. **Import Dependencies**:
```python
import subprocess
import webbrowser
import time
from pathlib import Path
```

2. **Validation**:
- Check if port is available (not already in use)
- Verify FastAPI app module exists (`codeframe.ui.app:app`)
- If project exists in cwd, load it; otherwise use global mode

3. **Start Server**:
```python
# Build uvicorn command
cmd = [
    "uvicorn",
    "codeframe.ui.app:app",
    "--host", host,
    "--port", str(port),
]

if reload:
    cmd.append("--reload")

# Print startup message
console.print(f"🌐 Starting dashboard server...")
console.print(f"   URL: [bold cyan]http://localhost:{port}[/bold cyan]")
console.print(f"   Press [bold]Ctrl+C[/bold] to stop\n")

# Start server
try:
    # Open browser after short delay
    if open_browser:
        time.sleep(1.5)  # Wait for server to start
        webbrowser.open(f"http://localhost:{port}")

    # Run server (blocking)
    subprocess.run(cmd, check=True)

except KeyboardInterrupt:
    console.print("\n✓ Server stopped")
except Exception as e:
    console.print(f"[red]Error starting server:[/red] {e}")
    raise typer.Exit(1)
```

4. **Error Handling**:
- Port already in use → suggest alternative port
- Module not found → installation instructions
- Permission denied → run with appropriate privileges

**Update Help Text**:
- Update `codeframe init` next steps to mention `serve` command
- Add `serve` to main CLI help output

#### Deliverables
- [x] `serve` command implemented in `codeframe/cli.py` ✅ (~92 lines)
- [x] Port availability check ✅ (`codeframe/core/port_utils.py`)
- [x] Auto-browser opening (optional) ✅ (`--no-browser` flag)
- [x] Graceful shutdown handling ✅ (Ctrl+C clean exit)
- [x] Updated CLI help text ✅
- [x] Unit tests (≥85% coverage) ✅ (100% coverage, 19 tests)
- [x] Manual test: `codeframe serve` opens dashboard successfully ✅

#### Test Coverage ✅ COMPLETE
- [x] Command accepts `--port`, `--host`, `--reload` flags ✅
- [x] Port already in use → helpful error message ✅
- [x] Ctrl+C graceful shutdown ✅
- [x] Browser opens automatically (can be disabled) ✅
- [x] Server starts successfully and serves requests ✅

**Test Results**:
- 17 unit tests (8 CLI + 9 port_utils)
- 2 integration tests (dashboard access)
- 100% coverage on port_utils module
- All 19 tests passing

---

### Feature 2: Project Creation Flow 🎯 CRITICAL WORKFLOW ✅ COMPLETED

**Status**: ✅ Merged (PR #24 - 2025-11-19)
**Effort**: 4 hours (Actual: ~4 hours)
**Priority**: P0 - Enables new user onboarding
**Issue**: Dashboard assumes project exists; no UI to create projects

#### Problem Statement

**Current Behavior**:
```
User opens http://localhost:8080
↓
Dashboard.tsx expects projectId prop
↓
Error: "Project not found" or blank page
↓
User has no way to create project via UI
```

**Expected Behavior**:
```
User opens http://localhost:8080
↓
Root route (/) shows ProjectCreationForm
↓
User fills: name, type, description
↓
Submits → POST /api/projects → Creates project
↓
Redirects to /projects/:id (Dashboard)
↓
Discovery begins automatically
```

#### Scope

**Frontend Changes**:

1. **Update Root Route** (`web-ui/src/app/page.tsx`):
```tsx
'use client';

import { useState } from 'react';
import { useRouter } from 'next/navigation';
import { ProjectCreationForm } from '@/components/ProjectCreationForm';
import { Spinner } from '@/components/Spinner';

export default function HomePage() {
  const router = useRouter();
  const [isCreating, setIsCreating] = useState(false);

  const handleProjectCreated = (projectId: number) => {
    console.log(`Project created with ID: ${projectId}`);
    router.push(`/projects/${projectId}`);
  };

  return (
    <div className="min-h-screen bg-gray-50 flex items-center justify-center p-4">
      <div className="max-w-2xl w-full">
        <div className="text-center mb-8">
          <h1 className="text-4xl font-bold text-gray-900 mb-2">
            Welcome to CodeFRAME
          </h1>
          <p className="text-lg text-gray-600">
            AI coding agents that work autonomously while you sleep
          </p>
        </div>

        {isCreating ? (
          <div className="text-center">
            <Spinner size="lg" />
            <p className="mt-4 text-gray-600">Creating your project...</p>
          </div>
        ) : (
          <ProjectCreationForm
            onSuccess={handleProjectCreated}
            onSubmit={() => setIsCreating(true)}
            onError={() => setIsCreating(false)}
          />
        )}
      </div>
    </div>
  );
}
```

2. **Update ProjectCreationForm Component** (`web-ui/src/components/ProjectCreationForm.tsx`):

Current issues:
- Missing `onSubmit` callback prop
- No loading state management
- No error handling

**Enhanced Implementation**:
```tsx
interface ProjectCreationFormProps {
  onSuccess: (projectId: number) => void;
  onSubmit?: () => void;
  onError?: (error: Error) => void;
}

export function ProjectCreationForm({
  onSuccess,
  onSubmit,
  onError
}: ProjectCreationFormProps) {
  const [formData, setFormData] = useState({
    name: '',
    projectType: 'python',
    description: '',
  });
  const [errors, setErrors] = useState<Record<string, string>>({});
  const [isSubmitting, setIsSubmitting] = useState(false);

  const validateForm = () => {
    const newErrors: Record<string, string> = {};

    if (!formData.name.trim()) {
      newErrors.name = 'Project name is required';
    } else if (formData.name.length < 3) {
      newErrors.name = 'Project name must be at least 3 characters';
    } else if (!/^[a-z0-9-_]+$/.test(formData.name)) {
      newErrors.name = 'Project name must contain only lowercase letters, numbers, hyphens, and underscores';
    }

    if (!formData.description.trim()) {
      newErrors.description = 'Project description is required';
    } else if (formData.description.length < 10) {
      newErrors.description = 'Description must be at least 10 characters';
    }

    setErrors(newErrors);
    return Object.keys(newErrors).length === 0;
  };

  const handleSubmit = async (e: React.FormEvent) => {
    e.preventDefault();

    if (!validateForm()) return;

    setIsSubmitting(true);
    onSubmit?.();

    try {
      const response = await fetch('/api/projects', {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify(formData),
      });

      if (!response.ok) {
        const error = await response.json();
        throw new Error(error.detail || 'Failed to create project');
      }

      const project = await response.json();
      onSuccess(project.id);

    } catch (error) {
      console.error('Failed to create project:', error);
      setErrors({ submit: error.message });
      onError?.(error);
      setIsSubmitting(false);
    }
  };

  return (
    <form onSubmit={handleSubmit} className="bg-white shadow-lg rounded-lg p-8">
      {/* Form fields */}
      <div className="mb-6">
        <label className="block text-sm font-medium text-gray-700 mb-2">
          Project Name *
        </label>
        <input
          type="text"
          value={formData.name}
          onChange={(e) => setFormData({ ...formData, name: e.target.value })}
          className={`w-full px-4 py-2 border rounded-lg ${
            errors.name ? 'border-red-500' : 'border-gray-300'
          }`}
          placeholder="my-awesome-app"
          disabled={isSubmitting}
        />
        {errors.name && (
          <p className="mt-1 text-sm text-red-600">{errors.name}</p>
        )}
      </div>

      <div className="mb-6">

        <select
          value={formData.projectType}
          onChange={(e) => setFormData({ ...formData, projectType: e.target.value })}
          className="w-full px-4 py-2 border border-gray-300 rounded-lg"
          disabled={isSubmitting}
        >
          <option value="python">Python (FastAPI, Flask, Django)</option>

          <option value="other">Other</option>
        </select>
      </div>

      <div className="mb-6">
        <label className="block text-sm font-medium text-gray-700 mb-2">
          Description *
        </label>
        <textarea
          value={formData.description}
          onChange={(e) => setFormData({ ...formData, description: e.target.value })}
          className={`w-full px-4 py-2 border rounded-lg ${
            errors.description ? 'border-red-500' : 'border-gray-300'
          }`}
          rows={4}
          placeholder="Describe what your project will do..."
          disabled={isSubmitting}
        />
        {errors.description && (
          <p className="mt-1 text-sm text-red-600">{errors.description}</p>
        )}
        <p className="mt-1 text-sm text-gray-500">
          {formData.description.length} characters (min 10)
        </p>
      </div>

      {errors.submit && (
        <div className="mb-6 p-4 bg-red-50 border border-red-200 rounded-lg">
          <p className="text-sm text-red-800">{errors.submit}</p>
        </div>
      )}

      <button
        type="submit"
        disabled={isSubmitting}
        className="w-full bg-blue-600 hover:bg-blue-700 disabled:bg-gray-400 text-white font-semibold py-3 px-6 rounded-lg transition-colors"
      >
        {isSubmitting ? 'Creating Project...' : 'Create Project & Start Discovery'}
      </button>

      <p className="mt-4 text-sm text-gray-500 text-center">
        After creation, you'll begin Socratic discovery with the Lead Agent
      </p>
    </form>
  );
}
```

3. **Add Spinner Component** (`web-ui/src/components/Spinner.tsx`):
```tsx
interface SpinnerProps {
  size?: 'sm' | 'md' | 'lg';
}

export function Spinner({ size = 'md' }: SpinnerProps) {
  const sizeClasses = {
    sm: 'w-4 h-4 border-2',
    md: 'w-8 h-8 border-3',
    lg: 'w-12 h-12 border-4',
  };

  return (
    <div
      className={`${sizeClasses[size]} border-blue-600 border-t-transparent rounded-full animate-spin`}
      role="status"
      aria-label="Loading"
    />
  );
}
```

**Backend Changes** (Minimal):

Verify `/api/projects` POST endpoint exists and handles:
- Project name validation (unique, valid characters)
- Database insertion
- Returns project ID in response

If missing, add to `codeframe/ui/app.py`:
```python
@app.post("/api/projects", response_model=ProjectResponse)
async def create_project(project: ProjectCreate):
    """Create a new project."""
    # Validate name
    if not re.match(r'^[a-z0-9-_]+$', project.name):
        raise HTTPException(400, "Invalid project name format")

    # Check if exists
    existing = await db.get_project_by_name(project.name)
    if existing:
        raise HTTPException(409, f"Project '{project.name}' already exists")

    # Create project
    project_id = await db.create_project(
        name=project.name,
        project_type=project.project_type,
        description=project.description,
    )

    return {"id": project_id, "name": project.name, "status": "created"}
```

#### Deliverables
- [x] Root route (`/`) renders ProjectCreationForm ✅
- [x] Form validation (name, description) ✅
- [x] POST to `/api/projects` endpoint ✅ (via `projectsApi.createProject`)
- [x] Success → redirect to `/projects/:id` ✅ (`router.push`)
- [x] Loading state during creation ✅ (Spinner component)
- [x] Error handling with user-friendly messages ✅ (409, 400, 500, network errors)
- [x] Unit tests for form validation (≥85% coverage) ✅ (48 tests passing)
- [x] Integration test: create project → redirects to dashboard ✅

#### Test Coverage ✅ COMPLETE
- [x] Form validation (empty fields, invalid name format, too short) ✅
- [x] Successful project creation flow ✅
- [x] API error handling (duplicate name, network error, server error) ✅
- [x] Loading state management ✅
- [x] Redirect after successful creation ✅
- [x] Spinner component (3 sizes, accessibility, animation) ✅
- [x] Character counter updates ✅
- [x] Submit button state management ✅

**Test Results**:
- 14 HomePage tests (page.test.tsx)
- 26 ProjectCreationForm tests (validation, submission, error handling)
- 8 Spinner tests (sizes, accessibility, styling)
- **Total**: 48 tests passing (100% pass rate)
- **Coverage**: Comprehensive coverage of all user stories

**Key Features Tested**:
- Welcome header and tagline rendering
- Form display and hiding during loading
- Loading spinner with three size variants
- Project name validation (required, min 3 chars, pattern /^[a-z0-9-_]+$/)
- Description validation (required, min 10 chars, max 500 chars)
- Character counter updates
- Submit button enabled/disabled states
- Input disabling during submission
- API integration with correct data format
- Error handling (409 duplicate, 400/422 validation, 500 server, network errors)
- Automatic redirect to `/projects/:id` after success
- Callback invocation order (onSubmit → API → onSuccess/onError)

**Bug Fixes**:
- Fixed invalid `border-3` class → `border-4` in Spinner (Tailwind CSS v3 compatibility)
- Removed non-functional project type dropdown (simplified UX)

### Feature 3: Discovery Answer UI Integration 🗣️ CRITICAL WORKFLOW ✅ COMPLETED

**Status**: ✅ Merged (PR #25 - 2025-11-19)
**Effort**: 6 hours (Actual: ~6 hours)
**Priority**: P0 - Makes discovery usable
**Issue**: Users see questions but cannot answer them

#### Problem Statement

**Current Behavior**:
```
Dashboard → DiscoveryProgress shows:
"Current Question: What problem does your project solve?"
↓
User sees question (read-only display)
↓
No input field, no submit button
↓
User confused: "Where do I type my answer?"
↓
User gives up (8/10 complexity score)
```

**Expected Behavior**:
```
Dashboard → DiscoveryProgress shows:
"Question 2 of 20: What problem does your project solve?"
↓
Textarea with placeholder: "Type your answer here..."
↓
Character counter: "0 / 5000 characters"
↓
Submit button enabled when answer > 0 chars
↓
User types answer → clicks Submit
↓
POST /api/projects/:id/discovery/answer
↓
Next question appears
↓
Progress bar updates: 10% → 15%
```

#### Scope

**Update DiscoveryProgress Component** (`web-ui/src/components/DiscoveryProgress.tsx`):

**Current Issues**:
- Lines 104-113 show current question READ-ONLY
- No answer input field
- No submit functionality
- Not integrated with ChatInterface

**Enhanced Implementation**:

1. **Add State Management**:
```tsx
interface DiscoveryProgressProps {
  projectId: number;
  refreshInterval?: number;
}

export function DiscoveryProgress({ projectId, refreshInterval = 5000 }: DiscoveryProgressProps) {
  const [discovery, setDiscovery] = useState<DiscoveryState | null>(null);
  const [answer, setAnswer] = useState('');
  const [isSubmitting, setIsSubmitting] = useState(false);
  const [error, setError] = useState<string | null>(null);
  const [successMessage, setSuccessMessage] = useState<string | null>(null);

  // ... existing fetch logic
```

2. **Add Answer Submission**:
```tsx
const submitAnswer = async () => {
  if (!answer.trim() || answer.length > 5000) {
    setError('Answer must be between 1 and 5000 characters');
    return;
  }

  setIsSubmitting(true);
  setError(null);

  try {
    const response = await fetch(
      `/api/projects/${projectId}/discovery/answer`,
      {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify({ answer: answer.trim() }),
      }
    );

    if (!response.ok) {
      const error = await response.json();
      throw new Error(error.detail || 'Failed to submit answer');
    }

    // Success
    setSuccessMessage('Answer submitted! Loading next question...');
    setAnswer(''); // Clear input

    // Refresh discovery state
    setTimeout(() => {
      fetchDiscoveryState();
      setSuccessMessage(null);
    }, 1000);

  } catch (err) {
    console.error('Failed to submit answer:', err);
    setError(err.message);
  } finally {
    setIsSubmitting(false);
  }
};

const handleKeyPress = (e: React.KeyboardEvent) => {
  // Ctrl+Enter to submit
  if (e.ctrlKey && e.key === 'Enter') {
    submitAnswer();
  }
};
```

3. **Enhanced UI Rendering**:
```tsx
return (
  <div className="bg-white rounded-lg shadow p-6">
    <div className="mb-4">
      <div className="flex justify-between items-center mb-2">
        <h3 className="text-lg font-semibold text-gray-900">
          Discovery Progress
        </h3>
        <span className="text-sm text-gray-500">
          {discovery?.currentQuestionIndex || 0} of {discovery?.totalQuestions || 20}
        </span>
      </div>

      {/* Progress bar */}
      <div className="w-full bg-gray-200 rounded-full h-2">
        <div
          className="bg-blue-600 h-2 rounded-full transition-all duration-300"
          style={{
            width: `${((discovery?.currentQuestionIndex || 0) / (discovery?.totalQuestions || 20)) * 100}%`
          }}
        />
      </div>
      <p className="text-sm text-gray-600 mt-1">
        {Math.round(((discovery?.currentQuestionIndex || 0) / (discovery?.totalQuestions || 20)) * 100)}% complete

        <p>Discovery has not started yet.</p>
      </div>
    )}
  </div>
);
```

**Backend Changes**:

Add POST endpoint for discovery answers (`codeframe/ui/app.py`):
```python
@app.post("/api/projects/{project_id}/discovery/answer")
async def submit_discovery_answer(
    project_id: int,
    answer: DiscoveryAnswer,
):
    """Submit answer to current discovery question."""
    # Validate project exists
    project = await db.get_project(project_id)
    if not project:
        raise HTTPException(404, "Project not found")

    # Validate discovery phase
    if project.phase != "discovery":
        raise HTTPException(400, "Project is not in discovery phase")

    # Validate answer length
    if not answer.answer.strip() or len(answer.answer) > 5000:
        raise HTTPException(400, "Answer must be between 1 and 5000 characters")

    # Get Lead Agent
    lead_agent = await get_lead_agent(project_id)

    # Process answer
    result = await lead_agent.process_discovery_answer(answer.answer)

    # Return updated state
    return {
        "success": True,
        "next_question": result.next_question,
        "is_complete": result.is_complete,
        "current_index": result.current_index,
        "total_questions": result.total_questions,
    }
```

**Pydantic Model**:
```python
class DiscoveryAnswer(BaseModel):
    answer: str = Field(..., min_length=1, max_length=5000)
```

#### Deliverables
- [x] Answer textarea in DiscoveryProgress component ✅

### Feature 4: Context Panel Integration 📊 VISIBILITY ✅ COMPLETED

**Status**: ✅ Merged (PR #26 - 2025-11-19)
**Effort**: 3 hours (Actual: ~4 hours with TypeScript fixes)
**Priority**: P0 - Provides transparency into context management
**Issue**: ContextPanel fully implemented but completely hidden from users

#### Problem Statement

**Current Behavior**:
```
ContextPanel.tsx exists (170 lines) ✅
ContextTierChart.tsx exists ✅
ContextItemList.tsx exists ✅
↓
Dashboard.tsx NEVER imports them ❌
↓
Users have ZERO visibility into:
- Flash saves (happen silently)
- What's in HOT/WARM/COLD tiers
- Why context was pruned
- Token usage vs limits
↓
Complexity score: 10/10 - "Feature exists but completely hidden"
```

**Expected Behavior**:
```
Dashboard → Tabs: [Overview] [Agents] [Context] [Settings]
↓
User clicks "Context" tab
↓
ContextPanel shows:
- Token usage: 50K / 180K (28%)
- Tier distribution chart
- HOT: 20 items (30K tokens)
- WARM: 45 items (15K tokens)
- COLD: 10 items (5K tokens)
↓
User understands what's in memory
```

#### Scope

**Update Dashboard Component** (`web-ui/src/components/Dashboard.tsx`):

**Current Structure** (lines 109-313):
- Header with project name, status, phase
- Progress section
- Agent cards section
- Blocker panel
- Activity feed
- Chat interface

**Add Tabbed Interface**:

1. **Install Dependencies** (if needed):
```bash
npm install @headlessui/react
```

2. **Import ContextPanel**:
```tsx
import { ContextPanel } from './context/ContextPanel';
import { Tab } from '@headlessui/react';
```

3. **Add Tab State**:
```tsx
const [selectedTab, setSelectedTab] = useState<'overview' | 'context'>('overview');
const [selectedAgentForContext, setSelectedAgentForContext] = useState<string | null>(null);
```

4. **Render Tabs**:
```tsx
<div className="container mx-auto px-4 py-6">
  {/* Header - stays above tabs */}
  <div className="mb-6">
    <h1 className="text-3xl font-bold text-gray-900">

      <span className="text-gray-600">Phase: {phase}</span>
      {connectionStatus && (
        <ConnectionStatus status={connectionStatus} />
      )}
    </div>
  </div>

            : 'text-gray-700 hover:bg-white/[0.12] hover:text-gray-900'
          }`

          </div>
        </div>
      </Tab.Panel>
    </Tab.Panels>
  </Tab.Group>
</div>
```

5. **Add Click Handler to AgentCard**:
```tsx
// In AgentCard.tsx, add onClick prop
interface AgentCardProps {
  agent: Agent;
  onClick?: () => void;
}

export function AgentCard({ agent, onClick }: AgentCardProps) {
  return (
    <div
      onClick={onClick}
      className="p-4 border rounded-lg hover:shadow-md transition-shadow cursor-pointer"
    >
      {/* ... existing content ... */}
    </div>
  );
}
```

**Alternative: Collapsible Section** (if tabs not preferred):
```tsx
<details className="mb-6">
  <summary className="cursor-pointer bg-white rounded-lg shadow p-4 hover:bg-gray-50">
    <h3 className="text-lg font-semibold inline">🧠 Context Management</h3>
    <span className="text-sm text-gray-500 ml-4">
      Click to expand
    </span>
  </summary>
  <div className="mt-2 bg-white rounded-lg shadow p-6">
    <ContextPanel agentId={selectedAgent} projectId={projectId} />
  </div>
</details>
```

### Feature 5: Session Lifecycle Management 🔄 CONTINUITY ✅ COMPLETED

**Status**: ✅ Merged (PR #28 - 2025-11-20)
**Effort**: 3 hours (Actual: ~3.5 hours)
**Priority**: P1 - Enables workflow continuity across sessions
**Issue**: Users lose context between sessions, breaking autonomous agent workflow
**Impact**: Critical for long-running projects and developer productivity

#### Problem Statement

**Current Behavior**:
```bash
$ codeframe start my-app
🚀 Agents working on Task #27: JWT refresh tokens
... user closes terminal ...

# Next day
$ codeframe start my-app
🚀 Starting project my-app...
# Where was I? What was I working on? What's next?
# User has to check dashboard, read logs, re-orient (5-10 minutes wasted)
```

**Expected Behavior**:
```bash
$ codeframe start my-app
📋 Restoring session...

Last Session:
  Summary: Completed Task #27 (JWT refresh tokens)
  Status: 3 tests failing in auth module
  Time: 2 hours ago

Next Actions:
  1. Fix JWT validation in kong-gateway.ts
  2. Add refresh token tests
  3. Update auth documentation

Progress: 68% (27/40 tasks complete)
Blockers: None

Press Enter to continue or Ctrl+C to cancel...
```

#### Scope

**Backend Changes**:

1. **Create SessionManager Class** (`codeframe/core/session_manager.py`):

```python
"""Session state persistence for continuous workflow."""

        return (completed / total * 100) if total > 0 else 0
```

3. **Update CLI Commands** (`codeframe/cli.py`):

```python
@app.command()
def start(project_name: Optional[str] = None):
    """Start/resume project execution."""
    project = load_project(project_name)
    lead_agent = LeadAgent(project.id)

    except KeyboardInterrupt:
        console.print("\n⏸  Pausing...")
    finally:
        # Save session state
        asyncio.run(lead_agent.on_session_end())
        console.print("✓ Session saved")

@app.command()
def resume(project_name: Optional[str] = None):
    """Resume paused project (alias for start)."""
    start(project_name)

@app.command()
def clear_session(project_name: Optional[str] = None):
    """Clear saved session state."""
    project = load_project(project_name)
    session_mgr = SessionManager(project.path)
    session_mgr.clear_session()
    console.print("✓ Session state cleared")
```

**Frontend Changes**:

4. **Add SessionStatus Component** (`web-ui/src/components/SessionStatus.tsx`):

```tsx
import { useState, useEffect } from 'react';
import { formatDistanceToNow } from 'date-fns';

interface SessionState {
  last_session: {
    summary: string;
    timestamp: string;
  };
  next_actions: string[];
  progress_pct: number;
  active_blockers: Array<any>;
}

interface SessionStatusProps {
  projectId: number;
}

export function SessionStatus({ projectId }: SessionStatusProps) {
  const [session, setSession] = useState<SessionState | null>(null);
  const [isLoading, setIsLoading] = useState(true);

  useEffect(() => {
    const fetchSession = async () => {
      try {
        const response = await fetch(`/api/projects/${projectId}/session`);
        if (response.ok) {
          const data = await response.json();
          setSession(data);
        }
      } catch (error) {
        console.error('Failed to fetch session state:', error);
      } finally {
        setIsLoading(false);
      }
    };

    fetchSession();
  }, [projectId]);

  if (isLoading) {
    return null;
  }

  if (!session) {
    return (
      <div className="bg-gray-50 border border-gray-200 rounded-lg p-4 mb-6">
        <p className="text-sm text-gray-600">🚀 Starting new session...</p>
      </div>
    );
  }

  return (
    <div className="bg-blue-50 border border-blue-200 rounded-lg p-4 mb-6">
      <h3 className="font-semibold text-blue-900 mb-3 flex items-center">
        📋 Session Context
      </h3>
      
      <div className="space-y-2 text-sm">
        <div>
          <span className="font-medium text-gray-700">Last session:</span>
          <p className="text-gray-900 mt-1">{session.last_session.summary}</p>
          <p className="text-xs text-gray-500 mt-1">
            {formatDistanceToNow(new Date(session.last_session.timestamp), { addSuffix: true })}
          </p>
        </div>

        {session.next_actions.length > 0 && (
          <div className="mt-3">
            <span className="font-medium text-gray-700">Next up:</span>
            <ul className="mt-1 space-y-1">
              {session.next_actions.slice(0, 3).map((action, idx) => (
                <li key={idx} className="text-gray-900 flex items-start">
                  <span className="text-blue-600 mr-2">→</span>
                  {action}
                </li>
              ))}
            </ul>
          </div>
        )}

        <div className="mt-3 flex items-center justify-between">
          <span className="text-xs font-medium text-gray-600">
            Progress: {session.progress_pct.toFixed(0)}%
          </span>
          {session.active_blockers.length > 0 && (
            <span className="text-xs text-orange-600">
              ⚠️ {session.active_blockers.length} blocker(s)
            </span>
          )}
        </div>
      </div>
    </div>
  );
}
```

5. **Integrate into Dashboard** (`web-ui/src/components/Dashboard.tsx`):

```tsx
import { SessionStatus } from './SessionStatus';

// In the Overview tab, add SessionStatus above DiscoveryProgress:
<Tab.Panel>
  <div className="grid grid-cols-1 lg:grid-cols-3 gap-6">
    <div className="lg:col-span-2 space-y-6">
      {/* Session Status - NEW */}
      <SessionStatus projectId={projectId} />
      
      {/* Existing components */}
      {progress && <ProgressBar {...progress} />}
      {phase === 'discovery' && <DiscoveryProgress projectId={projectId} />}
      {/* ... rest of components ... */}
    </div>
  </div>
</Tab.Panel>
```

6. **Add API Endpoint** (`codeframe/ui/app.py`):

```python
@app.get("/api/projects/{project_id}/session")
async def get_session_state(project_id: int):
    """Get current session state for project."""
    project = await db.get_project(project_id)
    if not project:
        raise HTTPException(404, "Project not found")
    
    session_mgr = SessionManager(project['path'])
    session = session_mgr.load_session()
    
    if not session:
        return {
            "last_session": {
                "summary": "No previous session",
                "timestamp": datetime.now().isoformat()
            },
            "next_actions": [],
            "progress_pct": 0,
            "active_blockers": []
        }
    
    return session
```

## Technical Architecture

### Component Diagram

```
CLI Layer:
├── serve command (NEW)
│   └── Starts uvicorn → FastAPI app
│
Web Layer:
├── / (root route) (NEW)
│   └── ProjectCreationForm
│       └── POST /api/projects → redirect to /projects/:id
│
├── /projects/:id (Dashboard)
    ├── Tabs: Overview | Context (NEW)
    │   ├── Overview Tab (existing content)
    │   └── Context Tab (NEW)
    │       └── ContextPanel (already exists, now visible)
    │
    └── DiscoveryProgress (ENHANCED)
        ├── Current question display
        ├── Answer textarea (NEW)
        ├── Submit button (NEW)
        └── POST /api/projects/:id/discovery/answer (NEW)
```

### API Endpoints

**New/Updated Endpoints**:

1. `POST /api/projects` - Create project
   - Request: `{ name, projectType, description }`
   - Response: `{ id, name, status }`
   - Validation: name format, uniqueness

2. `POST /api/projects/:id/discovery/answer` - Submit discovery answer
   - Request: `{ answer }`
   - Response: `{ success, next_question, is_complete, current_index }`
   - Validation: answer length (1-5000 chars)

3. `GET /api/agents/:id/context/stats` - Get context stats (existing, verify)
4. `GET /api/agents/:id/context/items` - Get context items (existing, verify)

### Database Changes

**No schema changes required** - all features use existing tables:
- `projects` table (already exists)
- `context_items` table (already exists)
- `discovery_state` (assumed to exist in project state)

### State Management

**Frontend State**:
- ProjectCreationForm: form data, validation errors, loading state
- DiscoveryProgress: answer text, submission state, error/success messages
- Dashboard: selected tab, selected agent for context view

**Backend State**:
- Discovery: current question index, answers array, completion status
- Context: tier assignments, token counts (already implemented)

---

## Testing Strategy

### Unit Testing

**CLI Tests** (`tests/test_cli.py`):
```python
def test_serve_command_default_port():
    """Test serve command with default port 8080."""

def test_serve_command_custom_port():
    """Test serve command with custom port via --port flag."""

def test_serve_command_port_in_use():
    """Test serve command when port already in use."""

def test_serve_command_no_browser():
    """Test serve command with --no-browser flag."""
```

**Frontend Tests**:

`web-ui/__tests__/components/ProjectCreationForm.test.tsx`:
```tsx
describe('ProjectCreationForm', () => {
  it('validates required fields');
  it('validates project name format');
  it('shows error for duplicate project name');
  it('calls onSuccess with project ID on successful creation');
  it('shows loading state during submission');
  it('handles API errors gracefully');
});
```

`web-ui/__tests__/components/DiscoveryProgress.test.tsx`:
```tsx
describe('DiscoveryProgress - Answer UI', () => {
  it('renders answer textarea when question available');
  it('disables submit when answer empty');
  it('shows character counter');
  it('validates answer length (max 5000)');
  it('submits answer on button click');
  it('submits answer on Ctrl+Enter');
  it('shows success message after submission');
  it('clears answer field after successful submission');
  it('shows error message on API failure');
});
```

`web-ui/__tests__/components/Dashboard.test.tsx`:
```tsx
describe('Dashboard - Tabs', () => {
  it('renders Overview tab by default');
  it('switches to Context tab on click');
  it('shows ContextPanel in Context tab');
  it('updates ContextPanel when agent selected');
  it('clicking agent card navigates to Context tab');
});
```

### Integration Testing

**End-to-End Workflow Tests**:

1. **New User Onboarding Flow**:
```
1. Run `codeframe serve`
2. Open browser to localhost:8080
3. Fill project creation form
4. Submit → verify redirect to /projects/:id
5. Verify discovery phase begins
6. Answer first discovery question
7. Verify next question appears
8. Complete discovery
9. Verify PRD generation begins
```

2. **Context Visibility Flow**:
```
1. Navigate to Dashboard
2. Click "Context" tab
3. Select agent from dropdown
4. Verify ContextPanel renders
5. Verify tier chart shows data
6. Verify context items list populated
```

---

## Risk Assessment

### Low Risk
- **Server start command**: Straightforward subprocess execution
- **Context integration**: Components already exist, just need wiring
- **Project creation**: Form logic is standard, endpoint likely exists

### Medium Risk
- **Discovery answer UI**: Requires backend endpoint changes
  - **Mitigation**: Verify endpoint exists first day, stub if needed

- **Tab integration**: UI library (Headless UI) might have version conflicts
  - **Mitigation**: Test tab switching early, have fallback to collapsible sections

### High Risk
- **Discovery state management**: Complex interaction between frontend and Lead Agent
  - **Mitigation**: Start with minimal implementation, add features incrementally
  - **Fallback**: If backend complex, make answer submission one-way (no validation)

---

## Dependencies

### External Dependencies
- `@headlessui/react` - For tab UI (if not already installed)
- `uvicorn` - Already installed (used for API server)
- All other dependencies already in package.json

### Internal Dependencies
- Sprint 9 must be complete (or near complete)
- Database migrations up-to-date
- FastAPI app running and tested
- WebSocket server functional

### Blockers
- If POST /api/projects endpoint missing → must build before testing project creation
- If Lead Agent discovery flow incomplete → discovery answers may not work end-to-end

---

## Success Metrics

### Quantitative
- [x] **Test Coverage**: Maintained ≥87% and improved ✅
- [x] **New Tests**: 2752+ tests passing (all 4 features) ✅
- [x] **Manual Checklist**: 80% items verified (Features 1-4 ✅)
- [x] **Load Time**: Dashboard loads in <2 seconds ✅
- [x] **No Regressions**: All existing tests still pass ✅

### Qualitative
- [x] **New user can create project via UI** ✅ (previously impossible)
- [x] **Discovery questions answerable** ✅ (previously impossible)
- [x] **Context visible and understandable** ✅ (previously hidden)
