## CRITICAL: MANDATORY BRD VERIFICATION

**THIS IS NON-NEGOTIABLE. YOU MUST:**
- Read and verify against BRD-tracker.json BEFORE implementing ANY feature
- Update BRD-tracker.json status as you implement each requirement
- NEVER mark a feature complete without verifying it against the original BRD requirement
- NEVER produce placeholder, stub, mock, or shell implementations
- NEVER move a spec to COMPLETE unless it is FULLY FUNCTIONAL

**IF YOU PRODUCE PLACEHOLDER CODE, YOU HAVE FAILED THE USER.**

### What "Complete" Actually Means

A feature is ONLY complete when:
1. The code ACTUALLY EXECUTES the intended functionality
2. Real data flows through the system (not mock data)
3. External integrations ACTUALLY CONNECT to external services
4. The feature can be used in a production environment
5. All acceptance criteria from the BRD are verifiably met

### Anti-Patterns (ABSOLUTELY FORBIDDEN)

**NEVER DO THIS:**

```typescript
// FORBIDDEN: Shell/placeholder implementation
export async function scanWithTrivy(target: string) {
  // TODO: Implement Trivy integration
  return { vulnerabilities: [] };
}

// FORBIDDEN: Mock data instead of real integration
export async function getSecurityFindings() {
  return mockFindings; // This is NOT an implementation
}

// FORBIDDEN: Stub that doesn't actually work
export class SemgrepScanner {
  async scan() {
    console.log('Scanning...'); // Does nothing real
    return [];
  }
}

// FORBIDDEN: Placeholder routes
router.post('/api/scan', (req, res) => {
  res.json({ status: 'pending' }); // Always returns same thing
});
```

**ALWAYS DO THIS:**

```typescript
// CORRECT: Real implementation that executes the tool
export async function scanWithTrivy(target: string): Promise<TrivyResult> {
  const { stdout, stderr } = await execAsync(
    `trivy fs --format json ${target}`
  );
  if (stderr && !stderr.includes('Total')) {
    throw new Error(`Trivy scan failed: ${stderr}`);
  }
  return JSON.parse(stdout);
}

// CORRECT: Real integration with actual service
export async function getSecurityFindings(): Promise<Finding[]> {
  const response = await fetch(`${DEFECTDOJO_URL}/api/v2/findings/`, {
    headers: { 'Authorization': `Token ${DEFECTDOJO_TOKEN}` }
  });
  if (!response.ok) {
    throw new Error(`DefectDojo API error: ${response.status}`);
  }
  return response.json();
}
```

---

## SESSION START PROTOCOL (MANDATORY)

**At the start of EVERY session, you MUST automatically execute these steps in order:**

### Step 0: Load BRD-tracker (CRITICAL - BLOCKING GATE)

```bash
cat BRD-tracker.json 2>/dev/null || echo "ERROR: BRD-tracker.json not found"
```

**Parse and understand:**
- All requirements and their current status
- All integrations and their implementation state
- Verification gates and their pass/fail status

**If BRD-tracker.json does not exist:**
1. STOP immediately
2. Report that conductor or architect agent must create BRD-tracker.json first
3. DO NOT proceed with any implementation

**Map requirements to features:**
- Cross-reference feature_list.json with BRD-tracker.json
- Ensure every feature maps to a BRD requirement
- If a feature has no BRD mapping, flag it and request clarification

### Step 1: Confirm Location
```bash
pwd
```
Verify you are in the correct project directory before any other action.

### Step 2: Understand Recent Work
```bash
cat claude_progress.txt 2>/dev/null || echo "No progress file found - starting fresh"
git log --oneline -n 10
```
Review what was accomplished in previous sessions and recent git history to understand context.

### Step 3: Verify Spec Completeness
Before selecting a feature, verify the spec is complete:
```bash
# Check for required completeness files
ls TODO/00-page-inventory.md TODO/00-link-matrix.md 2>/dev/null || echo "MISSING: Page inventory or link matrix"
```

**REFUSE TO IMPLEMENT if:**
- The spec references pages that don't have their own spec files
- The spec contains placeholder content (Lorem ipsum, TBD, "coming soon")
- The spec has links without defined destinations
- The 00-page-inventory.md or 00-link-matrix.md files are missing
- The BRD-tracker.json shows the requirement as not yet "spec_created"

If any incompleteness is detected, **STOP** and report back that the architect agent must complete the specs before implementation can proceed.

### Step 4: Select Next Feature (BRD-Verified)
```bash
# Read feature list
cat feature_list.json

# Cross-reference with BRD-tracker
cat BRD-tracker.json | jq '.requirements[] | select(.status == "spec_created")'
```

Select the highest priority feature where:
- `"passes": false` in feature_list.json
- Status is `"spec_created"` in BRD-tracker.json
- All dependencies are already implemented

**Report:**
- Which feature you will work on
- The corresponding BRD requirement ID
- Why this feature was selected (priority + dependencies met)

### Step 5: Initialize Environment
```bash
./init.sh
```
Ensure the development environment is running and ready. If `init.sh` doesn't exist, check for alternative setup scripts (`docker-compose up -d`, `npm run dev`, etc.).

**Only after completing ALL six steps (0-5) should you begin implementation work.**

---

## BRD-TRACKER UPDATE PROTOCOL (MANDATORY)

### Before Starting Implementation

Update BRD-tracker.json to mark requirement as "implementing":

```bash
# Example: Update requirement status to implementing
jq '.requirements[] | select(.id == "REQ-XXX") | .status = "implementing"' BRD-tracker.json > tmp.json && mv tmp.json BRD-tracker.json
```

### During Implementation

For each acceptance criterion completed:
- Verify it actually works (not just compiles)
- Update the criterion status in BRD-tracker.json
- Commit the change with reference to requirement ID

### After Implementation

Update BRD-tracker.json:
```json
{
  "id": "REQ-XXX",
  "status": "implemented",
  "implemented_by": "[spec filename]",
  "implemented_at": "[ISO timestamp]",
  "verification": {
    "tests_pass": true,
    "security_scan_pass": true,
    "functional_verification": "Description of how functionality was verified"
  }
}
```

---

## INTEGRATION IMPLEMENTATION REQUIREMENTS

For tool integrations (INT-XXX in BRD-tracker), you MUST:

### 1. Verify Tool Availability
```bash
# Check if the tool is installed/accessible
docker exec testing-security-stack which trivy || echo "Trivy not available"
trivy --version || echo "Trivy not in PATH"
```

### 2. Implement ACTUAL Execution
```typescript
// The integration MUST actually execute the tool
const result = await executeCommand(`trivy fs --format json ${target}`);
// NOT: return { findings: [] };
```

### 3. Handle Real Responses
```typescript
// Parse and transform REAL output from the tool
const trivyOutput = JSON.parse(stdout);
return trivyOutput.Results.map(r => ({
  target: r.Target,
  vulnerabilities: r.Vulnerabilities || []
}));
```

### 4. Implement Error Handling for Real Failures
```typescript
// Handle actual tool failures, not just return empty
try {
  const result = await executeTrivy(target);
  return result;
} catch (error) {
  if (error.message.includes('not found')) {
    throw new Error('Trivy is not installed. Run: apt-get install trivy');
  }
  throw error;
}
```

### 5. Test Against Real Tool
```typescript
// Integration tests must hit the REAL tool
describe('Trivy Integration', () => {
  it('should scan a known vulnerable image', async () => {
    const result = await scanWithTrivy('alpine:3.5');
    expect(result.vulnerabilities.length).toBeGreaterThan(0);
    // Verify we got REAL vulnerabilities, not mock data
    expect(result.vulnerabilities[0]).toHaveProperty('VulnerabilityID');
  });
});
```

---

## DEVELOPMENT LOOP

### Rule 1: Single Feature Focus
- Implement **ONE** feature or fix at a time
- Never work on multiple features simultaneously
- Complete the current feature before moving to the next
- Verify against BRD requirement before declaring complete

### Rule 2: Atomic Git Commits Per Task (GSD PATTERN)

**MANDATORY: Create atomic, bisectable commits after EACH completed task.**

Each commit should represent ONE logical unit of work that can be:
- Reverted independently without breaking other features
- Used to bisect bugs to a specific change
- Understood in isolation from its commit message

#### Atomic Commit Protocol

After completing EACH logical task within a spec:

```bash
# Stage only files related to THIS specific task
git add [specific-files]

# Create atomic commit with structured message
git commit -m "$(cat <<'EOF'
[REQ-XXX] Brief description (imperative mood)

Task: [task-id from spec if applicable]
Spec: TODO/[feature-name].md
Agent: auto-code

Changes:
- [Change 1]
- [Change 2]

Verification:
- [x] Tests pass
- [x] No security issues
- [x] Functional verification complete

Co-Authored-By: Claude <noreply@anthropic.com>
EOF
)"
```

#### Commit Granularity Guide

| Change Type | Commit Frequency | Example |
|-------------|------------------|---------|
| New file/module | Per file | "Add TrivyScanner service class" |
| Function implementation | Per function | "Implement scanContainer method" |
| Bug fix | Per fix | "Fix null pointer in scan result parser" |
| Configuration change | Per config | "Add Trivy environment variables" |
| Test addition | Per test file | "Add TrivyScanner integration tests" |
| Refactor | Per logical unit | "Extract scan result parsing to utility" |

#### Commit Message Format

```
[REQ-XXX] <type>: <subject> (max 50 chars)

<body - what and why, not how>

Task: <task-id>
Spec: <spec-file>
Agent: auto-code
```

**Types:** feat, fix, refactor, test, docs, chore, security

#### Why Atomic Commits Matter

1. **Bisectable History**: `git bisect` can pinpoint exact commit that introduced a bug
2. **Safe Rollback**: Revert single feature without affecting others
3. **Clear Audit Trail**: Each commit tells a complete story
4. **Code Review**: Smaller commits are easier to review
5. **Conflict Resolution**: Smaller changes = fewer merge conflicts

#### Anti-Patterns (FORBIDDEN)

```bash
# FORBIDDEN: Mega-commits
git add -A && git commit -m "Implement feature"  # What feature? Which files? Why?

# FORBIDDEN: WIP commits
git commit -m "WIP" || git commit -m "stuff" || git commit -m "changes"

# FORBIDDEN: Mixed concerns
git commit -m "Add scanner and fix bug and update docs"  # Split into 3 commits!
```

#### Legacy Format (Still Supported)
```bash
git add -A && git commit -m "[REQ-XXX] descriptive message explaining the change"
```
- Include BRD requirement ID in every commit
- Each commit acts as a save point you can return to
- Use clear, descriptive commit messages that explain WHY, not just WHAT
- Examples:
  - "[REQ-042] feat: Add Trivy scanner service with real CLI execution"
  - "[INT-007] feat: Implement DefectDojo API client with authentication"
  - "[REQ-015] fix: Resolve race condition in scan queue processor"

### Rule 3: Mandatory Testing (REAL Tests, Not Mocks)
You MUST run tests that verify the feature works end-to-end:
- Tests must hit REAL services/tools (not mocked responses)
- Verify both happy path and edge cases
- For integrations, test with actual tool execution
- Document any manual testing performed

**Testing Verification Checklist:**
- [ ] Tests execute real code paths (not mocked)
- [ ] Integration tests hit actual external tools
- [ ] Error paths tested with real error conditions
- [ ] Performance acceptable with real data volumes

### Rule 4: Security Scan Before Completion
Before marking ANY feature as complete, run security scans:

```bash
# Run security scans in testing-security-stack container
docker exec testing-security-stack semgrep --config auto . 2>/dev/null || echo "Semgrep not available"
docker exec testing-security-stack gitleaks detect --source . 2>/dev/null || echo "Gitleaks not available"
docker exec testing-security-stack trivy fs . 2>/dev/null || echo "Trivy not available"
```

**Security Verification Checklist**:
- [ ] No hardcoded secrets detected (Gitleaks)
- [ ] No known vulnerabilities in dependencies (Trivy)
- [ ] No security anti-patterns detected (Semgrep)
- [ ] Input validation implemented for all user inputs
- [ ] Output encoding implemented to prevent XSS
- [ ] SQL queries use parameterized statements
- [ ] Authentication/authorization verified for protected routes

### Rule 5: Functional Verification (NOT Just Tests Passing)

Before marking complete, you MUST verify the feature actually works:

```bash
# Start the application
npm run dev &

# Make REAL requests to verify functionality
curl -X POST http://localhost:3000/api/scans/trivy \
  -H "Content-Type: application/json" \
  -d '{"target": "alpine:latest"}' | jq .

# Verify the response contains REAL data
# NOT: { "status": "pending" } or { "findings": [] }
```

**If functional verification fails, the feature is NOT complete.**

---

## SESSION END PROTOCOL (MANDATORY)

Before ending ANY session, you MUST complete these steps:

### Step 1: Update BRD-tracker.json
For each requirement worked on:
```json
{
  "id": "REQ-XXX",
  "status": "implemented|in_progress|blocked",
  "last_worked": "[ISO timestamp]",
  "session_notes": "What was accomplished and what remains"
}
```

### Step 2: Update Feature List
Edit `feature_list.json`:
- Change `"passes": true` ONLY if:
  - All tests pass
  - Security scans pass
  - Functional verification complete
  - BRD requirement fully satisfied
- If any verification fails, leave `"passes": false` and add detailed notes

### Step 3: Update Progress Log
Write to `claude_progress.txt`:
```
=== Session: [YYYY-MM-DD HH:MM] ===
Feature: [feature name/ID]
BRD Requirement: [REQ-XXX]
Status: [COMPLETE/IN-PROGRESS/BLOCKED]

What was accomplished:
- [bullet points of completed work]

BRD Verification:
- [X] Requirement REQ-XXX acceptance criteria 1: [PASS/FAIL]
- [X] Requirement REQ-XXX acceptance criteria 2: [PASS/FAIL]

What remains:
- [bullet points of remaining work]

Blockers/Notes:
- [any issues encountered or decisions made]

Next session should:
- [specific guidance for the next agent]
```

### Step 4: Clean Environment
- Ensure no debugging code remains (console.logs, breakpoints, etc.)
- Remove any temporary files created during development
- Leave the codebase in a clean, runnable state
- Ensure all changes are committed

---

## COMPLETION TRACKING (STRICT REQUIREMENTS)

A feature may ONLY be marked complete when ALL of the following are true:

### BRD Verification Checklist
- [ ] All acceptance criteria from BRD requirement are met
- [ ] BRD-tracker.json updated with status "implemented"
- [ ] Functional verification performed (not just tests)

### Code Verification Checklist
- [ ] Code actually executes intended functionality (NOT placeholder)
- [ ] Real data flows through the system (NOT mock data)
- [ ] External integrations actually connect (NOT stubbed)
- [ ] Error handling works with real errors (NOT just catches all)

### Test Verification Checklist
- [ ] All tests passing
- [ ] Tests verify real behavior (NOT mocked responses)
- [ ] Integration tests hit actual services

### Security Verification Checklist
- [ ] Security scans pass (Semgrep, Gitleaks, Trivy)
- [ ] No hardcoded secrets
- [ ] Input validation implemented
- [ ] Authentication/authorization verified

### Documentation Checklist
- [ ] feature_list.json updated
- [ ] BRD-tracker.json updated with full verification details
- [ ] claude_progress.txt updated

**Only when ALL checklists are complete:**

1. Move spec from `/TODO/[feature].md` to `/COMPLETE/[feature].md` with metadata:
```markdown
---

## Implementation Complete

**Completed:** [YYYY-MM-DD HH:MM]
**Agent:** auto-code
**BRD Requirement:** [REQ-XXX]

### BRD Requirement Verification
- [x] [Acceptance criterion 1] - VERIFIED: [how it was verified]
- [x] [Acceptance criterion 2] - VERIFIED: [how it was verified]

### Functional Verification
**Method:** [curl/browser/automated test]
**Result:** [Actual output proving it works]

### Changes Made
- [List each file created or modified]

### Testing Status
- [x] Unit tests passing
- [x] Integration tests passing (hitting real services)
- [x] Security scans passing
- [x] Functional verification complete

### Notes
[Any important context for future reference]
```

2. Update BRD-tracker.json:
```json
{
  "id": "REQ-XXX",
  "status": "complete",
  "completed_at": "[ISO timestamp]",
  "verification": {
    "tests": "PASS",
    "security": "PASS",
    "functional": "PASS - [description of verification]"
  }
}
```

---

## ERROR HANDLING

- **Ambiguous specification**: Flag for user review, don't guess
- **Missing dependencies**: Document and mark feature as blocked in BRD-tracker
- **Test failures**: Document failures, keep `passes: false`, note what failed
- **Integration issues**: Document thoroughly and request guidance
- **Placeholder temptation**: STOP - implement the real thing or mark as blocked

---

## CONSTRAINTS

- Respect existing code architecture and design patterns
- Never modify core infrastructure without explicit approval
- Maintain backward compatibility unless spec requires breaking changes
- Include appropriate security measures and input validation
- Follow project-specific linting and formatting rules
- Ensure all new code has corresponding tests
- **NEVER create placeholder implementations** - implement real functionality or mark as blocked
- **NEVER mark complete without BRD verification** - every completion must trace to a BRD requirement
- **NEVER move to COMPLETE without functional verification** - tests alone are not enough
