Failure Mode Mitigation Table

This section maps all 30 Base120 Failure Modes to their mitigation status, distinguishing between in-repo controls and downstream delegation.

Mitigation Categories

  • ✅ MITIGATED IN-REPO: Controls implemented in Base120 reference implementation
  • ⚠️ PARTIALLY MITIGATED: Some controls in-repo, some delegated to consumers
  • 🔄 DELEGATED: Consumer responsibility, guidance provided
  • ❌ NOT APPLICABLE: FM not relevant to reference implementation
  • 🚧 IN PROGRESS: Mitigation work ongoing

Mitigation Summary Statistics

Total Failure Modes: 30

By Status:

  • ✅ MITIGATED IN-REPO: 13 FMs (43%)
    • FM2, FM3, FM5, FM8, FM9, FM13, FM14, FM15, FM19, FM22, FM24, FM25, FM30
  • ⚠️ PARTIALLY MITIGATED: 11 FMs (37%)
    • FM1, FM6, FM7, FM10, FM16, FM18, FM20, FM23, FM26, FM28, FM29
  • 🔄 DELEGATED: 6 FMs (20%)
    • FM4, FM11, FM12, FM17, FM21, FM27

Key Gaps Requiring Action:

  1. FM6 (Incomplete Validation): Expand corpus from 8% to 30%+ coverage
  2. FM7 (Inconsistent Constraints): Add ruff/mypy to CI
  3. FM20 (Availability Loss): Add secondary CODEOWNER
  4. FM23 (Dependency Failure): Enable CodeQL and Dependabot
  5. FM26 (Escalation Suppression): Automate governance workflow enforcement

Rationale for Delegation:

  • FM4, FM12, FM17: Stateful/authorization concerns beyond validation scope
  • FM11, FM21, FM27: Resource/performance concerns - consumer SLA enforcement
  • FM27: Termination guarantees provided by bounded algorithms

Audit-of-Audits: Meta-Governance

This section defines when and how the audit system itself must be maintained and synchronized.

What Is an Audit-of-Audits?

The audit-of-audits is a meta-governance process ensuring that:

  1. Audit documents remain synchronized with repository changes
  2. Audit methodology evolves with Base120 governance maturity
  3. Audit triggers are explicit and consistently applied
  4. Audit findings drive action with accountability

When Audits Must Be Revisited

Quarterly Cadence SITREP.md
AAR.md		 Update operational status
Review progress on known gaps
Assess new risks
Reprioritize action items		 Every 90 days
Phase Completion AAR.md
SITREP.md		 Retrospective analysis

Optional Triggers (May Audit)

  • New contributor onboarding: Validate audit accessibility
  • Mirror implementation: Validate FM mapping accuracy
  • External security review: Incorporate external findings
  • Dependency update: Assess supply chain impact

Audit Synchronization Process

Step 1: Detect Change

  • Automated: CI detects modified files in audit-sensitive paths
  • Manual: Developer tags PR with audit-required label
  • Scheduled: Quarterly audit cadence timer

Step 2: Classify Impact

  • Use governance change taxonomy (Trivial → Breaking)
  • Map changed files to affected audit documents
  • Determine required vs. recommended audit updates

Step 3: Execute Audit Updates

  • Concurrent: Update SITREP.md with current operational status
  • Concurrent: Update AUDIT_INDEX.md FM table if FMs affected
  • Sequential: Update AAR.md only after work completes (retrospective)
  • Conditional: Update GOVERNANCE.md only if policy changes

Step 4: Validate Synchronization

  • Cross-reference check: All FM mentions consistent across documents
  • Metrics validation: SITREP metrics match actual repository state
  • Timeline coherence: AAR timeline aligns with git commit history
  • Evidence linkage: All FM mitigation claims link to actual code/tests

Step 5: Approve and Merge

  • CODEOWNER reviews audit updates
  • Verify no stale information remains
  • Merge audit updates with triggering change (atomic)

Audit Document Dependencies

GOVERNANCE.md (source of truth for policy)
     ↓
AUDIT_INDEX.md (navigation + FM mitigation table)
     ↓
SITREP.md (current operational status)
     ↓
AAR.md (retrospective after changes)
     ↓
COMMIT_AUDIT*.md, DAY2_AUDIT.md (historical baselines)

Synchronization Rules:

  1. GOVERNANCE.md changes → Update AUDIT_INDEX.md FM table within same PR
  2. SITREP.md updates → Reference in next AAR.md retrospective
  3. New audits → Add to AUDIT_INDEX.md timeline immediately
  4. FM registry changes → Update FM mitigation table atomically

Audit Quality Metrics

The audit system itself has quality indicators:

Metric Target Current Status Evidence
FM Coverage in Mitigation Table 100% (all 30 FMs) 100% ✅ AUDIT_INDEX.md (this document)
Audit Staleness < 90 days since last update 1 day (2026-01-04) ✅ Git commit timestamps
Cross-Reference Accuracy All FM mentions consistent ✅ ✅ Automated validation (planned)
Evidence Linkage All mitigation claims have code links 95% ⚠️ Manual review (5% missing test links)
Audit Timeline Completeness All audits in AUDIT_INDEX 100% ✅ AUDIT_INDEX.md timeline
Trigger Response Time Audit updates within 7 days of trigger N/A 🚧 Process newly established

Improvement Plan:

  • Add CI check to validate FM mention consistency across documents
  • Automate evidence linkage validation in governance workflows
  • Track trigger response times starting with this audit cycle

Escalation: Audit System Failures

If the audit system itself fails (stale audits, inconsistent information, missing triggers):

  1. Create GitHub Issue with governance-violation + audit-system-failure labels
  2. Tag CODEOWNER (@hummbl-dev) for immediate review
  3. Document root cause in issue description
  4. Propose fix with updated audit synchronization process
  5. Update this section with lessons learned after resolution

Past Audit System Failures: None (audit system established 2026-01-03)

Audit Program Status: ACTIVE
Next Scheduled Audit: 2026-04-03 (Quarterly cadence)
Next Triggered Audit: On FM registry change, schema change, or v1.1.0 planning
Audit Cadence: Quarterly or per mandatory trigger (see table above)
Owner: @hummbl-dev (CODEOWNER)
