# Phase 3 - Immediate Fix Plan

**Goal:** Resolve deployment blockers and achieve 100% build success
**Timeline:** 6-12 hours
**Status:** 🔴 URGENT

---

## Fix 1: TypeScript Compilation Errors

**Priority:** P0 (Critical Blocker)
**Estimated Time:** 2-4 hours
**Assigned To:** Frontend Developer

### Files to Fix

#### 1. `export-import.worker.ts` (8 errors)

**Location:** `/frontend/apps/web/src/workers/export-import.worker.ts`

**Errors:**
- Lines 382-412: Type guards missing for optional objects
- Line 384: `T | undefined` not assignable to `T`
- Line 394: Generic type instantiation issues

**Fix Strategy:**
```typescript
// Before
const result = cache.get(key);
return result.value;

// After
const result = cache.get(key);
if (!result) {
  throw new Error('Cache miss');
}
return result.value;
```

**Action Items:**
- [ ] Add type guard: `if (!result) return undefined`
- [ ] Use optional chaining: `result?.value`
- [ ] Add explicit type annotations where needed

---

#### 2. `graphLayout.worker.ts` (5 errors)

**Location:** `/frontend/apps/web/src/workers/graphLayout.worker.ts`

**Errors:**
- Line 91: `logger` is not defined
- Line 91: `error` is not defined
- Line 92: `error` is not defined
- Line 657: `logger` is not defined
- Line 275: Unused variable `nodeId`

**Fix Strategy:**
```typescript
// Add at top of file
const logger = {
  error: (msg: string, err?: Error) => {
    console.error(msg, err);
    postMessage({ type: 'error', error: msg });
  }
};

// Or import from utility
import { createLogger } from '../lib/logger';
const logger = createLogger('GraphLayoutWorker');
```

**Action Items:**
- [ ] Import or create logger utility
- [ ] Define error type or use Error
- [ ] Remove unused `nodeId` variable (line 275) or mark with `// eslint-disable-next-line @typescript-eslint/no-unused-vars`

---

#### 3. `search-index.worker.ts` (28 errors)

**Location:** `/frontend/apps/web/src/workers/search-index.worker.ts`

**Errors:**
- Lines 79-96: Object is possibly 'undefined' (12 errors)
- Lines 260-286: `update` is possibly 'undefined' (14 errors)
- Lines 125, 276: Unused variable `field`

**Fix Strategy:**
```typescript
// Before
const doc = index.documents[id];
doc.score = calculateScore(doc);

// After
const doc = index.documents[id];
if (!doc) {
  throw new Error(`Document ${id} not found`);
}
doc.score = calculateScore(doc);

// Or with optional chaining
const doc = index.documents[id];
if (doc) {
  doc.score = calculateScore(doc);
}
```

**Action Items:**
- [ ] Add null checks before accessing `document` properties
- [ ] Add null checks before accessing `update` properties
- [ ] Remove or prefix unused `field` variables with underscore: `_field`

---

#### 4. `WorkerPool.ts` (2 errors)

**Location:** `/frontend/apps/web/src/workers/WorkerPool.ts`

**Errors:**
- Line 114: Type mismatch in task queue
- Line 328: Timeout type conversion error

**Fix Strategy:**
```typescript
// Error 1: Type mismatch
// Before
const task: WorkerTask<T, R> = queue.get();
tasks.push(task);

// After
const task = queue.get() as WorkerTask<unknown, unknown>;
tasks.push(task);

// Error 2: Timeout conversion
// Before
const timeout: number = setTimeout(...);

// After
const timeout = setTimeout(...) as unknown as number;
// Or use ReturnType<typeof setTimeout>
const timeout: ReturnType<typeof setTimeout> = setTimeout(...);
```

**Action Items:**
- [ ] Fix generic type constraint on line 114
- [ ] Use proper type for setTimeout return value (NodeJS.Timeout vs number)

---

### Verification Commands

```bash
# 1. Navigate to frontend
cd frontend/apps/web

# 2. Run TypeScript compiler
bun run build

# Expected output: ✅ No errors

# 3. Run tests to ensure no regressions
bun test src/__tests__/workers/

# Expected: All tests pass

# 4. Test workers in browser
bun run dev
# Open browser, check DevTools for worker errors
```

---

## Fix 2: Security Audit Completion

**Priority:** P1 (Important)
**Estimated Time:** 4-8 hours
**Assigned To:** Security Engineer

### Tasks

#### 1. Run Automated Scans (1 hour)

```bash
# Frontend dependency audit
cd frontend/apps/web
npm audit --production
bun audit

# Backend dependency audit
cd backend
go list -json -m all | nancy sleuth

# Static analysis
cd frontend/apps/web
bun run lint --fix
```

**Action Items:**
- [ ] Document all findings in spreadsheet
- [ ] Categorize by severity (Critical/High/Medium/Low)
- [ ] Identify false positives

---

#### 2. Manual Security Review (2-3 hours)

**Areas to Review:**
- [ ] Authentication flows (WorkOS integration)
- [ ] Authorization checks (API endpoints)
- [ ] Input validation (all user inputs)
- [ ] SQL injection vectors (parameterized queries)
- [ ] XSS vulnerabilities (output encoding)
- [ ] CSRF protection (token validation)
- [ ] CORS configuration (allowed origins)
- [ ] Rate limiting (all public endpoints)
- [ ] Secrets management (no hardcoded credentials)

**Checklist:**
Use `/docs/checklists/SECURITY_AUDIT_CHECKLIST.md`

---

#### 3. Document Findings (1-2 hours)

**Create:** `/docs/reports/PHASE_3_SECURITY_AUDIT_REPORT.md`

**Template:**
```markdown
# Phase 3 Security Audit Report

**Audit Date:** 2026-02-01
**Auditor:** [Name]
**Scope:** Phase 3 implementations

## Executive Summary
[Overall security posture, rating out of 10]

## Findings Summary

# Verify no critical vulnerabilities
npm audit --audit-level=high
# Expected: 0 critical, 0 high
```

---

## Fix 3: Environment Configuration

**Priority:** P0 (Critical Blocker)
**Estimated Time:** 30 minutes
**Assigned To:** DevOps Engineer

### Tasks

#### 1. Verify `.env.example` (10 minutes)

```bash
cd /Users/kooshapari/temp-PRODVERCEL/485/kush/trace

# Check all required variables documented
cat .env.example

# Compare with actual usage in code
grep -r "process.env\." frontend/apps/web/src --include="*.ts" | \
  grep -oP "process.env.\K\w+" | sort -u > /tmp/used-vars.txt

grep "^[A-Z_]*=" .env.example | \
  cut -d= -f1 | sort -u > /tmp/documented-vars.txt

diff /tmp/used-vars.txt /tmp/documented-vars.txt
# Expected: No differences (or only optional vars)
```

**Action Items:**
- [ ] Add missing variables to `.env.example`
- [ ] Add comments explaining each variable
- [ ] Ensure no sensitive values in example file

---

#### 2. Create Production `.env` (10 minutes)

**Store in secure location (1Password, AWS Secrets Manager, etc.)**

```bash
# Template
WORKOS_CLIENT_ID=client_XXXXX
WORKOS_API_KEY=sk_XXXXX
WORKOS_REDIRECT_URI=https://tracertm.com/auth/callback

DATABASE_URL=postgresql://user:pass@db-host:5432/tracertm
REDIS_URL=redis://redis-host:6379

AWS_S3_BUCKET=tracertm-production
AWS_ACCESS_KEY_ID=AKIAXXXXX
AWS_SECRET_ACCESS_KEY=XXXXX

GITHUB_APP_ID=123456
GITHUB_APP_PRIVATE_KEY="-----BEGIN RSA PRIVATE KEY-----\n...\n-----END RSA PRIVATE KEY-----"

LINEAR_API_KEY=lin_api_XXXXX

OPENAI_API_KEY=sk-XXXXX
ANTHROPIC_API_KEY=sk-ant-XXXXX
```

**Action Items:**
- [ ] Obtain all production credentials
- [ ] Store securely (NOT in git)
- [ ] Create K8s secrets
  ```bash
  kubectl create secret generic tracertm-secrets \
    --from-env-file=production.env \
    -n tracertm
  ```

---

#### 3. Verify K8s Secrets (10 minutes)

```bash
# Check secrets exist
kubectl get secrets -n tracertm

# Verify secret keys
kubectl describe secret tracertm-secrets -n tracertm

# Test deployment can access secrets
kubectl apply -k k8s/overlays/staging --dry-run=client
```

**Action Items:**
- [ ] Secrets created in all namespaces (staging, production)
- [ ] Deployment manifests reference secrets correctly
- [ ] No plain-text secrets in git
