🔧 Function Audit

Functions with Zero Coverage:

In the bounded-execution directory, the following functions are completely untested:

• finite-disclosure.ts:
  • Statement coverage only 9.26% (83/504 statements covered)
  • Branch coverage critically low at 0.26% (3/380 branches covered)
  • Only 4.54% of functions tested (2/44)
  • This is a security-sensitive module for container disclosure restrictions

Highlights (100% Coverage):

• All config validation (src/config/)
• All constants (src/constants/)
• All service functions (src/services/)
• All runtime abstractions (src/runtime/)
• Docker abstraction layer (src/docker/)
• Parsers module (src/parsers/)
• Log aggregation module (src/logs/)

🔎 Notable Findings

1. 🚨 Critical Gap in Bounded Execution — finite-disclosure.ts has only 9.26% statement coverage and 0.26% branch coverage. This module handles container disclosure restrictions, a security-sensitive function. Immediate test coverage is essential.

2. ✅ Security Core Fully Tested — All primary firewall enforcement components (squid-config.ts, host-iptables.ts, docker-manager.ts) have 100% coverage. This is excellent for a security-critical system.

3. ⚠️ Enclave Branch Coverage Weakness — While enclave statement coverage is solid (80–99%), branch coverage lags (46–78%), suggesting conditional logic paths are under-tested. This is particularly concerning for runtime-preflight.ts (46.51% branch coverage).

4. 📈 High Overall Quality — 93.02% statement coverage and 86.33% branch coverage across the entire codebase exceeds industry standards for security-critical infrastructure.

🎯 Recommendations

High Priority

1. Fix bounded-execution/finite-disclosure.ts Coverage (CRITICAL)
   • Current: 9.26% statements, 0.26% branches
   • Target: ≥80% statements, ≥70% branches
   • Impact: Prevents container disclosure attacks
   • Action: Add unit tests covering all code paths for disclosure restriction logic

Medium Priority

2. Improve Enclave Branch Coverage

   • Current: runtime-preflight.ts (46.51% branches), enclave/manager.ts (68.42% branches)
   • Target: ≥80% branch coverage
   • Impact: Ensures error handling and edge case paths are tested
   • Action: Add parameterized tests for conditional branches in preflight checks and manager state machines

3. Enhance src/cli.ts Branch Coverage

   • Current: 50% branches (though 85.71% statements)
   • Target: ≥75% branches
   • Impact: Ensures all command-line flag combinations are tested
   • Action: Add integration tests for flag combinations and error paths
