TheFlow a19b0978ea feat(governance): Phase 0 complete - 100% enforcement + defense coverage

Phase 0 fixes completed before baseline collection:

1. Defense-in-Depth Layer 1 (.gitignore)
   - Added missing credential file patterns
   - *.pem, *.key, *.p12, *.pfx
   - credentials.json, secrets, *.secret
   - config/secrets.json, auth.json
   - Verification: ✅ All critical patterns in .gitignore

2. Defense-in-Depth Layer 5 (Credential Rotation)
   - Created docs/CREDENTIAL_ROTATION_PROCEDURES.md
   - MongoDB password rotation procedures
   - API key rotation procedures
   - SSH/deployment key rotation
   - Git history credential removal
   - Emergency contact procedures
   - Verification: ✅ Rotation procedures documented

3. inst_083 Enforcement Recognition
   - Updated scripts/audit-enforcement.js
   - Added inst_083: ['scripts/session-init.js']
   - Documents handoff auto-injection enforcement
   - Verification: ✅ 40/40 imperative instructions (100%)

4. Session-closedown Dev Server Protection
   - Fixed scripts/session-closedown.js
   - Added port 9000 check to prevent killing dev server
   - Prevents disruption during active development
   - Verification: ✅ Dev server preserved during cleanup

Baseline Metrics Collected:

- Enforcement Coverage: 40/40 (100%)
- Defense-in-Depth: 5/5 layers (100%)
- Framework Activity: 1,204+ audit logs, 162 blocks
- Research data saved to docs/research-data/metrics/

Research Documentation Plan:

- Created docs/RESEARCH_DOCUMENTATION_DETAILED_PLAN.md
- 150+ granular tasks across 6 phases
- User decisions confirmed (Working Paper v0.1)
- Scope: Development-time governance only
- Author: John G Stroh
- Contact: research@agenticgovernance.digital
- Status: Phase 0 complete, ready for Phase 1

Results:

✅ 100% enforcement coverage (architectural)
✅ 100% defense-in-depth (all 5 layers)
✅ All 6 framework services operational
✅ Clean baseline established for research paper
✅ Dev server protection implemented

Next: Phase 1 (Metrics Gathering & Verification)

Credential Rotation Procedures

Purpose: Defense-in-Depth Layer 5 (inst_072) Status: Active Last Updated: 2025-10-25

🚨 When to Rotate Credentials

Rotate credentials IMMEDIATELY if any of the following occur:

Confirmed Exposure: Credential detected in git history, logs, or public location
Suspected Compromise: Security incident, unauthorized access attempt, or anomalous activity
Personnel Change: Team member with credential access leaves or changes role
Scheduled Rotation: Regular rotation per security policy (recommended: 90 days)
Detection Alert: Pre-commit hook blocked credential, GitHub secret scanning alert

📋 Rotation Procedures by Credential Type

MongoDB Database Password

Location: .env file (MONGODB_URI)

Rotation Steps:

Generate new strong password (16+ characters, mixed case, numbers, symbols)
Update MongoDB user: mongosh tractatus_dev --eval "db.changeUserPassword('tractatus_user', 'NEW_PASSWORD')"
Update .env file with new password
Test connection: npm test -- --testPathPattern=mongodb.test.js
Restart application
Verify application works
Document rotation in security log

Rollback: Keep old password active for 24 hours, then revoke

🔍 Git History Credential Removal

If credentials were committed to git history:

Remove from history: git filter-repo --path .env --invert-paths
Force push (coordinate with team first): git push origin --force --all
Rotate ALL exposed credentials
Notify GitHub Security Team (if public repo)

📊 Rotation Log

Location: logs/credential-rotations.log

Format: [TIMESTAMP] ROTATION | Credential: TYPE | Reason: REASON | Performed By: EMAIL | Status: SUCCESS/FAILED

🛡️ Prevention Measures

Never commit credentials (use .env files, already in .gitignore)
Pre-commit hooks active (inst_069)
Use credential vault (KeePassXC recommended)
GitHub secret scanning enabled
Regular security audits

🚨 Emergency Contact

Immediate: Rotate exposed credentials
Within 1 hour: Notify security@agenticgovernance.digital
Within 24 hours: Complete incident report
Within 1 week: Review and update procedures
