🔧 Function Audit

Fully Tested Functions (100% coverage):

• 15+ core security functions in host-iptables*.ts (network isolation)
• 10+ domain validation functions in domain-*.ts (domain ACL enforcement)
• 14+ config writer functions in config-writer.ts (configuration generation)
• 22+ container lifecycle functions in container-lifecycle.ts (container orchestration)
• 7+ DNS resolver functions in dns-resolver.ts (DNS configuration)

Untested/Partially Tested Functions:

• bounded-execution/finite-disclosure.ts: 0 functions covered (9.26% statements)

  • Core disclosure rate limiting logic untested
  • No branch coverage on critical path

• enclave/runtime-preflight.ts: Preflight checks incomplete (~66% coverage)

  • Error handling paths need additional tests
  • Enclave initialization edge cases missing

• commands/validators/config-assembly.ts: Assembly validation partial (~73% coverage)

  • Complex branch conditions (25% branch coverage) suggest untested validation paths

📅 Recent Source Changes (last 7 days)

Recent improvements focus on:

• Bounded execution module: Core disclosure rate limiting (9.26% → needs urgent test coverage)
• Enclave runtime: Preflight checks (66.66% coverage)
• Cloud Hypervisor: rootfs module integration (71.69% coverage)
• Config validators: Assembly validators (73.68% coverage)

🔎 Notable Findings

1. 📈 Exceptional Overall Coverage: 92.66% statement coverage and 93.24% function coverage demonstrate robust test suite quality across most codebase.

2. 🔴 Critical Gap in bounded-execution/finite-disclosure.ts: Only 9.26% statement coverage and 0.26% branch coverage on a security-critical rate limiting module. This is the highest priority for remediation.

3. ✅ Security Module Excellence: All network isolation (host-iptables*.ts), domain filtering (domain-*.ts), and squid configuration modules have 100% coverage, ensuring firewall enforcement is fully tested.

4. 🚀 Container Orchestration Ready: container-lifecycle.ts (96.27%), cli-workflow.ts (98.63%), and related modules demonstrate comprehensive testing of startup/shutdown paths and resource management.

🎯 Recommendations

1. 🔴 HIGH PRIORITY: Fix bounded-execution/finite-disclosure.ts Coverage

• Impact: Critical disclosure rate-limiting module with <10% coverage
• Action: Add comprehensive unit tests covering:
  • Rate limit threshold enforcement
  • Token consumption and bucket refill logic
  • Edge cases (burst capacity, zero rates, negative values)
  • Integration with agent disclosure flow
• Acceptance: Achieve ≥80% statement and ≥75% branch coverage
• Estimated effort: 8–12 hours

2. 🟡 MEDIUM PRIORITY: Improve enclave/runtime-preflight.ts Branch Coverage

• Impact: Enclave startup verification at 66% statements, 41% branches
• Action: Add tests for:
  • Preflight validation edge cases (missing capabilities, platform mismatches)
  • Error handling and recovery paths
  • Enclave readiness timeout scenarios
• Acceptance: Achieve ≥85% statement and ≥70% branch coverage
• Estimated effort: 6–8 hours

3. 🟡 MEDIUM PRIORITY: Expand config-assembly.ts Branch Coverage

• Impact: Config validator with 73% statements but only 25% branch coverage
• Action: Test complex branching logic:
  • Config precedence scenarios
  • Validation error paths and messages
  • Multiple enclave configurations
• Acceptance: Achieve ≥80% branch coverage
• Estimated effort: 5–7 hours
