### ❌ Failing Tests (25/37 - 68%)

#### Checkpoint UI Tests (8/9 failing)
All checkpoint tests timeout waiting for components to render. Common timeout: 30.6-30.8 seconds.

**Pattern**: Tests wait for `[data-testid="checkpoint-panel"]` and related elements but they never appear.

**Possible Causes**:
1. Checkpoint API endpoint returns data but frontend doesn't display it
2. CheckpointList component has rendering issue
3. Test selectors don't match actual component structure
4. Data format mismatch between API and frontend expectations

**Failing Tests**:
- should display checkpoint panel
- should list existing checkpoints
- should open create checkpoint modal
- should validate checkpoint name input
- should show restore confirmation dialog
- should display checkpoint diff preview
- should display checkpoint metadata
- should allow deleting checkpoint

**Note**: We seeded 3 checkpoints via API (confirmed successful in logs), so data exists.

---

#### Dashboard Tests (6/11 failing)
Several dashboard sections timeout waiting for panels to appear.

**Failing Tests**:
1. **should display all main dashboard sections** (REGRESSION!)
   - Previously passing (Phase 1)
   - Now failing after adding test data
   - Suggests component loading issue when data present

2. **should display review findings panel**
   - We seeded 7 code review findings
   - Panel not rendering

3. **should display quality gates panel**
   - No quality gate data seeded (known gap)
   - Expected failure

4. **should display checkpoint panel**
   - Same as checkpoint UI tests
   - Checkpoints exist but panel not rendering

5. **should display metrics and cost tracking panel**
   - We seeded 15 token usage records
   - Panel not rendering despite data

6. **should receive real-time updates via WebSocket**
   - WebSocket connection test
   - May be timing issue

7. **should navigate between dashboard sections** (REGRESSION!)
   - Previously passing
   - Now failing
   - Suggests navigation broken when data present

8. **should display task progress and statistics**
   - We seeded 10 tasks
   - Task statistics not displaying

---

#### Metrics UI Tests (6/12 failing)
Some metrics tests pass, others fail. Mixed results.

**Failing Tests**:
1. **should display metrics panel** - Panel not rendering
2. **should display total cost** - Cost display not showing
3. **should display token usage statistics** - Token stats not showing
4. **should display token usage chart** - Chart not rendering
5. **should display cost breakdown by agent** - Agent breakdown not showing
6. **should display cost breakdown by model** - Model breakdown not showing

**Passing Tests** (for context):
- Cost trend chart ✅
- Model pricing info ✅
- Export CSV ✅
- Cost per task ✅
- Date filter ✅
- Real-time refresh ✅

**Pattern**: Some chart/visualization tests pass, but basic display tests fail. Suggests conditional rendering logic may be filtering out data.

---

#### Review UI Tests (2/6 failing)
Most review tests pass! Only 2 failures.

**Failing Tests**:
1. **should display review findings panel** - Panel not rendering
2. **should display review score chart** - Chart not showing

**Passing Tests**:
- Severity badges ✅
- Expand/collapse findings ✅
- Filter by severity ✅
- Actionable recommendations ✅

**Analysis**: Review finding details work great, but top-level panel/chart don't render. Suggests parent container issue.

## Failure Patterns Identified

### Pattern 1: Timeout Failures (Most Common)
**Symptom**: Tests timeout at 30.6-30.8 seconds waiting for elements
**Affected**: 23/25 failures
**Root Cause Candidates**:
1. Frontend components expect data in different format than backend provides
2. Components have conditional rendering that hides elements when data exists
3. API responses are slow or failing silently
4. Test selectors don't match actual DOM structure

### Pattern 2: Regression Failures
**Symptom**: Tests that passed in Phase 1 now fail in Phase 2
**Affected Tests**:
- "should display all main dashboard sections"
- "should navigate between dashboard sections"

**Analysis**: Adding test data broke previously working tests. Suggests:
1. Components break when data is present (null pointer issues)
2. Navigation logic depends on empty state
3. Data format mismatch causes render failure

### Pattern 3: Missing Data (Expected Failures)
**Symptom**: Tests fail because data wasn't seeded
**Affected**: Quality gates tests
**Note**: We didn't seed quality gate results (schema uncertainty)

---

## Root Cause Hypotheses (Ranked by Likelihood)

### Hypothesis 1: Data Format Mismatch (HIGH CONFIDENCE - 80%)
**Evidence**:
- We seed data directly into database bypassing API layer
- Frontend expects API response format (envelopes, nested objects)
- Database stores raw data (flat rows)
- Tests timeout waiting for elements that never render

**Example**:
```python
# We insert into DB:
cursor.execute("INSERT INTO agents (...) VALUES (...)")

# But frontend expects API response:
{
  "agents": [
    { "id": "lead-001", "type": "lead", ... }
  ],
  "meta": { "total": 5 }
}
```

**Fix**: Add project-agent assignments to `project_agents` table (multi-agent architecture from PR #37)

---

### Hypothesis 2: Component Rendering Bugs (MEDIUM CONFIDENCE - 60%)
**Evidence**:
- Some tests regressed (previously passing, now failing)
- Mixed results in same component (some metrics tests pass, others fail)
- Checkpoint tests all fail despite data existing

**Example**:
```tsx
// Component might do:
if (checkpoints.length === 0) {
  return <EmptyState />
}
// But never renders CheckpointList when data exists
```

**Fix**: Debug components in browser dev tools, check for JavaScript errors

---

### Hypothesis 3: Test Selector Issues (LOW CONFIDENCE - 30%)
**Evidence**:
- Review tests mostly pass (good selectors)
- Checkpoint tests all fail (bad selectors?)

**Fix**: Verify test-id attributes match actual component structure

---

## Data Seeding Status

### ✅ Fully Seeded (Working)
1. **Agents** (5) - lead, backend, frontend, test, review
2. **Tasks** (10) - 3 completed, 2 in-progress, 2 blocked, 3 pending
3. **Token Usage** (15) - Sonnet, Opus, Haiku across 3 days
4. **Code Reviews** (7) - 3 findings for task #2, 4 findings for task #4
5. **Checkpoints** (3) - Via API (confirmed successful)

### ⚠️ Partially Seeded
6. **Project-Agent Assignments** (MISSING)
   - Critical for multi-agent architecture
   - Required by `project_agents` table
   - Frontend may filter agents without project assignment

### ❌ Not Seeded
7. **Quality Gate Results** (0) - Schema uncertain, skipped
8. **Activity Feed** (0) - Schema uncertain, skipped

---

## Strategic Recommendations

### Priority 1: Add Project-Agent Assignments (HIGH IMPACT)
**Effort**: 30 minutes
**Impact**: May fix 10-15 test failures

**Rationale**: PR #37 introduced `project_agents` junction table for multi-agent architecture. Agents must be assigned to projects via this table for frontend to display them.

**Implementation**:
```python
# In seed-test-data.py, after seeding agents:
cursor.execute("""
    INSERT INTO project_agents (project_id, agent_id, role, is_active)
    VALUES
        (?, 'lead-001', 'orchestrator', 1),
        (?, 'backend-worker-001', 'backend', 1),
        (?, 'frontend-specialist-001', 'frontend', 1),
        (?, 'test-engineer-001', 'testing', 1),
        (?, 'review-agent-001', 'review', 1)
""", (project_id,) * 5)
```

---

### Priority 2: Debug Frontend Component Rendering (MEDIUM IMPACT)
**Effort**: 1-2 hours
**Impact**: May fix 5-8 test failures

**Approach**:
1. Run frontend locally with seeded database
2. Open browser dev tools
3. Check for JavaScript errors in console
4. Verify API calls return expected data
5. Inspect React component tree
6. Fix any null pointer or format issues

---

### Priority 3: Add Quality Gate Seeding (LOW IMPACT)
**Effort**: 45 minutes
**Impact**: Fixes 1-2 test failures

**Rationale**: Lower priority since we're already at 32% pass rate. Focus on higher-impact fixes first.

---

### Priority 4: Fix Test Assertions (LOW IMPACT)
**Effort**: 1 hour
**Impact**: Fixes 0 failures (prevents false positives)

**Rationale**: Some passing tests have weak assertions (e.g., `count() >= 0`). These don't fail now but should be strengthened to catch regressions.

---
