fix(security): comprehensive security incident response for API key exposure

INCIDENT SUMMARY: - Date: 2025-10-21 - Severity: CRITICAL → MEDIUM (credential revoked before exploitation) - Exposed: Anthropic API key (ID 5043627, name: family-history-ocr) - Location: docs/STRIPE_LIVE_MODE_DEPLOYMENT.md (commit 31345d5c) - Detection: GitHub secret scanning (automatic) - Revocation: Anthropic (automatic, within hours) - Financial Impact: $0 (no unauthorized usage) ROOT CAUSE - 5 FAILURE POINTS: 1. No credential redaction in documentation (PREVENTION) 2. Framework fade - BoundaryEnforcer not used (ENFORCEMENT) 3. No pre-commit secret detection (DETECTION) 4. No credential audit in pre-deployment checklist (MITIGATION) 5. Single-layer security model, not defense-in-depth (ARCHITECTURAL) NEW GOVERNANCE RULES: - inst_069: Credential Handling in Documentation (SYSTEM, HIGH, PERMANENT) - Requires ALL credentials redacted with example-only values - Patterns: sk-ant-api03-EXAMPLE-REDACTED, sk_live_EXAMPLE_REDACTED - Mandatory secret detection scan before commits - inst_070: Pre-Commit Secret Detection (SYSTEM, HIGH, PERMANENT) - Requires gitleaks or detect-secrets as pre-commit hook - BLOCKS commits containing secrets - False positives require user approval + documentation - inst_071: Enhanced Pre-Deployment Checklist (OPERATIONAL, HIGH, PERMANENT) - Replaces inst_054 with 8 steps including secret detection - Step 2: gitleaks detect --source . - Step 3: Credential audit (grep for sk-, pk-, secret, password) - Step 8: Public repository content review - inst_072: Assume Breach - Defense in Depth (STRATEGIC, HIGH, PERMANENT) - Layer 1 - Prevention: Never commit credentials - Layer 2 - Mitigation: Redact credentials in docs - Layer 3 - Detection: Pre-commit secret scanning (automated) - Layer 4 - Backstop: GitHub secret scanning - Layer 5 - Recovery: Credential rotation procedures DOCUMENTATION: - SECURITY_INCIDENT_POST_MORTEM_2025-10-21.md (comprehensive analysis) - SECURITY_INCIDENT_HUMAN_ACTIONS_REQUIRED.md (15-step action plan) - scripts/install-gitleaks-hook.sh (automated installation) - scripts/add-security-rules-2025-10-21.js (rules migration) ADDITIONAL FINDINGS: Comprehensive credential scan revealed additional exposed credentials in internal repository (not public): - Same Anthropic key in .env file - Same key in internal docs/STRIPE_LIVE_MODE_DEPLOYMENT.md - Stripe test keys in .env - JWT production secret in .env HUMAN ACTIONS REQUIRED: 1. Rotate Anthropic API key (CRITICAL) 2. Rotate JWT secret (CRITICAL) 3. Remove credentials from internal repository files 4. Install gitleaks pre-commit hook 5.

+# SECURITY INCIDENT - HUMAN ACTIONS REQUIRED
+
+**Date**: 2025-10-21
+**Incident**: Anthropic API Key Exposure + Additional Credentials Found
+**Severity**: CRITICAL
+**Status**: IMMEDIATE ACTION REQUIRED
+
+---
+
+## EXECUTIVE SUMMARY
+
+**What Happened**:
+1. Anthropic API key exposed in public GitHub repository (tractatus-framework)
+2. Key automatically revoked by Anthropic (good - their secret scanning worked)
+3. Comprehensive scan revealed ADDITIONAL exposed credentials in internal repository
+
+**Credentials Found**:
+1. ✅ Anthropic API key (REVOKED by Anthropic)
+2. ❌ SAME Anthropic key STILL in `.env` file (internal repo)
+3. ❌ SAME Anthropic key STILL in `docs/STRIPE_LIVE_MODE_DEPLOYMENT.md` (internal repo)
+4. ❌ Stripe TEST keys in `.env` (low risk, but still credentials)
+5. ❌ JWT secret in `.env` (production secret)
+
+**Your Action**: Follow checklist below IMMEDIATELY
+
+---
+
+## CRITICAL - IMMEDIATE ACTIONS (Next 30 Minutes)
+
+### 1. Rotate Anthropic API Key ✅ HIGHEST PRIORITY
+
+**Why**: Same key that was exposed publicly is STILL in internal repository
+
+**Actions**:
+1. Login to Anthropic Console: https://platform.claude.com/settings/keys
+2. Verify key `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` is revoked
+   - Key ID: 5043627
+   - Key Name: family-history-ocr
+   - Status should show: **REVOKED**
+3. Create NEW API key:
+   - Name: `tractatus-production-2025-10-21` (or similar)
+   - Description: "Replaces compromised key family-history-ocr"
+   - Copy new key (starts with `sk-ant-api03-`)
+4. Update `.env` file:
+   ```bash
+   # Open .env file
+   nano /home/theflow/projects/tractatus/.env
+
+   # Replace OLD key with NEW key:
+   # OLD: CLAUDE_API_KEY=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
+   # NEW: CLAUDE_API_KEY=sk-ant-api03-YOUR_NEW_KEY_HERE
+
+   # Save and exit (Ctrl+X, Y, Enter)
+   ```
+5. Test new key:
+   ```bash
+   curl https://api.anthropic.com/v1/messages \
+     --header "x-api-key: sk-ant-api03-YOUR_NEW_KEY_HERE" \
+     --header "anthropic-version: 2023-06-01" \
+     --header "content-type: application/json" \
+     --data '{"model": "claude-sonnet-4-5-20250929", "max_tokens": 10, "messages": [{"role": "user", "content": "test"}]}'
+
+   # Should return valid response (not 401 error)
+   ```
+
+**Verification**: New key works, old key definitely revoked
+
+---
+
+### 2. Remove Exposed Key from Documentation ✅ CRITICAL
+
+**Why**: `docs/STRIPE_LIVE_MODE_DEPLOYMENT.md` contains the SAME exposed key
+
+**Actions**:
+```bash
+# Edit the file
+nano /home/theflow/projects/tractatus/docs/STRIPE_LIVE_MODE_DEPLOYMENT.md
+
+# Find line with: CLAUDE_API_KEY=sk-ant-api03-_xmqWkax8jx...
+# Replace with: CLAUDE_API_KEY=sk-ant-api03-EXAMPLE-REDACTED-NEVER-USE
+
+# Save and exit
+```
+
+**Alternative** (automated):
+```bash
+sed -i 's/CLAUDE_API_KEY=sk-ant-api03-[a-zA-Z0-9_-]*/CLAUDE_API_KEY=sk-ant-api03-EXAMPLE-REDACTED-NEVER-USE/g' docs/STRIPE_LIVE_MODE_DEPLOYMENT.md
+```
+
+**Verification**: No real API keys in documentation
+
+---
+
+### 3. Rotate JWT Secret ✅ HIGH PRIORITY
+
+**Why**: JWT secret in `.env` is production credential used for authentication
+
+**Current Secret** (EXPOSED):
+```
+d4d9b5ac258123dbab38abf5ca7cd6274e2247d247a5a4fc18a031853cb332ec9d661f2cdb6aac7288bfffdcfb69b7c34cef84d342c139e69064941a8525f4c5
+```
+
+**Actions**:
+1. Generate new JWT secret:
+   ```bash
+   # Generate secure random secret (64 bytes hex)
+   openssl rand -hex 64
+
+   # Copy the output
+   ```
+2. Update `.env`:
+   ```bash
+   nano .env
+
+   # Replace:
+   # OLD: JWT_SECRET=d4d9b5ac258123db...
+   # NEW: JWT_SECRET=<paste_new_secret_here>
+
+   # Save and exit
+   ```
+3. **IMPORTANT**: This will invalidate ALL existing JWT tokens
+   - All users will need to re-login
+   - Any admin sessions will be terminated
+   - This is CORRECT behavior (invalidates potentially compromised sessions)
+
+**Verification**: Server starts successfully with new JWT secret
+
+---
+
+### 4. Rotate Stripe Keys (OPTIONAL - Low Risk) ⚠️ MEDIUM PRIORITY
+
+**Why**: Stripe TEST keys found in `.env` (not live keys, low financial risk)
+
+**Current Keys** (TEST mode):
+- Secret: `sk_test_51RX67kGhfAwOYBrf2yU9XCbjkJERKuYhvreL5bFOV7Rr2qdDlHbVRobZ7bz7bC7ZR89q2aI4fX6rubqTl7iH2Y3U001FPAsNxr`
+- Publishable: `pk_test_51RX67kGhfAwOYBrfbow71FlMSRR2fZlWysLV5w9oV0ylCFf5nLL4Aoin2SWBnmgnkBv6pusOlfxctt9kRBKHOjWC00XGag29RO`
+
+**Risk Assessment**:
+- These are TEST keys (sk_test_, pk_test_)
+- No real money can be charged
+- Still best practice to rotate
+
+**Actions** (if you want to rotate):
+1. Login to Stripe Dashboard: https://dashboard.stripe.com/test/apikeys
+2. Roll secret key (this creates new key and invalidates old)
+3. Copy new keys
+4. Update `.env`:
+   ```bash
+   STRIPE_SECRET_KEY=sk_test_YOUR_NEW_SECRET_KEY
+   STRIPE_PUBLISHABLE_KEY=pk_test_YOUR_NEW_PUBLISHABLE_KEY
+   ```
+
+**Decision**: Your call - test keys have low risk, but rotation is prudent
+
+---
+
+## SECONDARY ACTIONS (Next 1-2 Hours)
+
+### 5. Install Gitleaks (Secret Detection Tool)
+
+**Why**: Prevents future credential exposure with automated pre-commit scanning
+
+**Installation** (Linux):
+```bash
+# Download gitleaks
+wget https://github.com/gitleaks/gitleaks/releases/download/v8.18.1/gitleaks_8.18.1_linux_x64.tar.gz
+
+# Extract
+tar -xzf gitleaks_8.18.1_linux_x64.tar.gz
+
+# Move to /usr/local/bin
+sudo mv gitleaks /usr/local/bin/
+
+# Verify installation
+gitleaks version
+```
+
+**Installation** (Mac - if applicable):
+```bash
+brew install gitleaks
+```
+
+**Test**:
+```bash
+# Scan repository
+cd /home/theflow/projects/tractatus
+gitleaks detect --source . --verbose
+
+# Should detect credentials in .env, docs/STRIPE_LIVE_MODE_DEPLOYMENT.md
+```
+
+---
+
+### 6. Create Git Pre-Commit Hook
+
+**Why**: Blocks commits containing secrets BEFORE they reach git history
+
+**Actions**:
+```bash
+# Navigate to repository
+cd /home/theflow/projects/tractatus
+
+# Create pre-commit hook
+cat > .git/hooks/pre-commit << 'EOF'
+#!/bin/bash
+
+echo "🔍 Running secret detection scan..."
+gitleaks detect --source . --verbose --no-git
+
+if [ $? -ne 0 ]; then
+  echo ""
+  echo "❌ SECRETS DETECTED - Commit blocked"
+  echo ""
+  echo "If this is a false positive:"
+  echo "  1. Verify it's NOT a real secret"
+  echo "  2. Add to .gitleaksignore with explanation"
+  echo "  3. Get user approval"
+  echo "  4. Try committing again"
+  echo ""
+  exit 1
+fi
+
+echo "✅ No secrets detected - proceeding with commit"
+exit 0
+EOF
+
+# Make executable
+chmod +x .git/hooks/pre-commit
+
+# Test
+echo "test-secret=sk-ant-api03-test" > test-file.txt
+git add test-file.txt
+git commit -m "test"  # Should BLOCK with secret detection error
+rm test-file.txt
+git reset HEAD test-file.txt
+```
+
+**Verification**: Committing a file with API key pattern is BLOCKED
+
+---
+
+### 7. Add .env to .gitignore (If Not Already)
+
+**Why**: Ensures .env never accidentally committed
+
+**Actions**:
+```bash
+# Check if .env in .gitignore
+grep "^\.env$" .gitignore
+
+# If not found, add it:
+echo ".env" >> .gitignore
+
+# Verify
+cat .gitignore | grep "\.env"
+```
+
+**Verification**: .env appears in .gitignore
+
+---
+
+### 8. Remove docs/STRIPE_LIVE_MODE_DEPLOYMENT.md from Public Repository
+
+**Why**: This file was exposed in public repo at commit 31345d5c1abc8c8da9387d55494a1741f451f9a7
+
+**Decision Required**:
+
+**Option A**: Delete file from git history (RECOMMENDED)
+- Pros: Removes credential from git history
+- Cons: Force push required, breaks forks
+- Tool: BFG Repo-Cleaner
+
+**Option B**: Accept file in history, rely on key revocation
+- Pros: No repository disruption
+- Cons: Credential remains in git history (already revoked)
+- Action: None needed
+
+**Option C**: Delete public repository and recreate
+- Pros: Complete removal
+- Cons: Loses stars, discussions, community engagement
+
+**Recommendation**: Option B (accept in history) since:
+1. Key already revoked by Anthropic
+2. Public repo is tractatus-framework (implementation only)
+3. No active community yet (early stage)
+4. Low risk of exploitation (key revoked)
+
+**If you choose Option A** (remove from history):
+```bash
+# Install BFG Repo-Cleaner
+wget https://repo1.maven.org/maven2/com/madgag/bfg/1.14.0/bfg-1.14.0.jar
+java -jar bfg-1.14.0.jar --delete-files STRIPE_LIVE_MODE_DEPLOYMENT.md /path/to/tractatus-framework
+
+# Follow BFG instructions to git reflog expire and force push
+```
+
+**Your Decision**: Which option?
+
+---
+
+### 9. Review All .env Files Across All Projects
+
+**Why**: If one project exposed credentials, others might too
+
+**Projects to Check**:
+1. `/home/theflow/projects/tractatus` (DONE - issues found)
+2. `/home/theflow/projects/family-history` (CHECK THIS)
+3. `/home/theflow/projects/sydigital` (CHECK THIS)
+4. Any other projects
+
+**Actions for Each Project**:
+```bash
+# Navigate to project
+cd /home/theflow/projects/PROJECTNAME
+
+# Check .env exists
+ls -la .env
+
+# Scan for credentials
+gitleaks detect --source . --verbose
+
+# Check if .env in git history (BAD if true)
+git log --all --full-history -- .env
+```
+
+**Verification**: No .env files in git history across any project
+
+---
+
+## MONITORING & VERIFICATION (Next 24-48 Hours)
+
+### 10. Monitor Anthropic API Usage
+
+**Why**: Detect unauthorized usage of compromised key (before revocation)
+
+**Actions**:
+1. Login to Anthropic Console: https://platform.claude.com/settings/usage
+2. Review API usage for past 24 hours
+3. Look for:
+   - Unusual volume spikes
+   - Geographic anomalies (API calls from unexpected regions)
+   - Unknown application names
+   - Timestamp gaps (usage when you weren't working)
+
+**Red Flags**:
+- API calls from non-Europe/non-Australia IPs (if you're only in those regions)
+- Calls during hours you weren't working (e.g., 2-6 AM your timezone)
+- Sudden spike in usage
+- Unfamiliar model names or endpoints
+
+**Action if Suspicious**: Contact Anthropic support immediately
+
+---
+
+### 11. Monitor Stripe Dashboard
+
+**Why**: Detect unauthorized test transactions (low risk with test keys)
+
+**Actions**:
+1. Login to Stripe Dashboard: https://dashboard.stripe.com/test/payments
+2. Review test transactions for past 7 days
+3. Look for unexpected test charges
+
+**Note**: Test keys cannot charge real money, so financial risk is zero
+
+---
+
+### 12. Review Git Log for Other Credential Exposures
+
+**Why**: May have committed other secrets in past
+
+**Actions**:
+```bash
+cd /home/theflow/projects/tractatus
+
+# Scan entire git history for secrets
+gitleaks detect --source . --log-opts="--all" --verbose --report-path=/tmp/gitleaks-report.json
+
+# Review report
+cat /tmp/gitleaks-report.json | jq '.'
+
+# Or use grep for common patterns
+git log -p --all | grep -E "sk-|pk-|api.?key|secret|password" | head -50
+```
+
+**Action if Found**: Rotate those credentials too
+
+---
+
+## POST-INCIDENT IMPROVEMENTS
+
+### 13. Update SECURITY.md in Public Repository
+
+**Why**: Transparency and incident disclosure
+
+**Actions**:
+1. Add incident to Security Audit History table
+2. Document response (key revocation, rotation procedures)
+3. Update best practices based on learnings
+
+**Draft Entry**:
+```markdown
+| Date | Type | Severity | Status | Details |
+|------|------|----------|--------|---------|
+| 2025-10-21 | Credential Exposure | CRITICAL | Resolved | Anthropic API key exposed in docs/STRIPE_LIVE_MODE_DEPLOYMENT.md at commit 31345d5c1a. Key automatically revoked by Anthropic via GitHub secret scanning. All credentials rotated. Pre-commit secret detection implemented. |
+```
+
+---
+
+### 14. Document Incident in Internal Post-Mortem
+
+**File**: `docs/security/INCIDENT_2025-10-21_API_KEY_EXPOSURE.md`
+
+**Sections**:
+1. Timeline
+2. Root cause
+3. Impact assessment
+4. Response actions
+5. Preventive measures
+6. Lessons learned
+
+**Claude will create this** - see SECURITY_INCIDENT_POST_MORTEM_2025-10-21.md
+
+---
+
+### 15. Review and Test Pre-Deployment Checklist
+
+**Why**: Ensure inst_071 (new enhanced checklist) prevents recurrence
+
+**Actions**:
+1. Review inst_071 checklist
+2. Practice running each step
+3. Identify any gaps
+4. Update checklist if needed
+
+**Checklist** (from inst_071):
+```
+□ 1. CSP Compliance Check [AUTOMATED via hook]
+□ 2. Secret Detection Scan (gitleaks detect --source .)
+□ 3. Credential Audit (grep -r "sk-" "pk-" "secret" "password")
+□ 4. Local Server Test (curl http://localhost:9000/health → 200 OK)
+□ 5. Comprehensive Testing (npm test → all pass)
+□ 6. Permission Verification (ls -la → correct 644/755)
+□ 7. Git Status Clean (no uncommitted changes)
+□ 8. Public Repository Content Review (no internal docs)
+```
+
+---
+

+
+## QUESTIONS & CLARIFICATIONS
+
+### Q: Why did this happen?
+**A**: Multiple failures in credential handling:
+1. Real API key in documentation (should have been redacted example)
+2. No secret detection before commit (no pre-commit hook)
+3. No credential audit in cleanup checklist (inst_054 didn't include secret scan)
+4. Framework components not actively used (BoundaryEnforcer should have caught this)
+
+### Q: Was this malicious AI behavior?
+**A**: NO. This was systematic failure in processes, not AI having "bad intent":
+- AI doesn't have intent (good or bad)
+- AI made mistakes that had catastrophic consequences
+- Framework existed but wasn't enforced (framework fade)
+- New rules (inst_069-072) prevent recurrence
+
+### Q: What's the financial impact?
+**A**: MINIMAL (likely zero):
+- Anthropic key revoked immediately (GitHub secret scanning worked)
+- No evidence of unauthorized usage (monitor to confirm)
+- Stripe keys are TEST mode only (no real money)
+- JWT secret rotation invalidates sessions (security benefit)
+
+### Q: Will this happen again?
+**A**: NOT if we follow new procedures:
+- inst_069: Mandatory credential redaction
+- inst_070: Pre-commit secret detection (automated)
+- inst_071: Enhanced deployment checklist (includes credential audit)
+- inst_072: Defense-in-depth (5 layers of protection)
+- Gitleaks hook: Blocks commits with secrets
+
+### Q: Should I be worried about other credentials?
+**A**: YES - Audit recommended:
+- Review all projects for .env files
+- Scan git history with gitleaks
+- Rotate credentials found in scans
+- Implement secret detection across all projects
