🔮 The ancient spirits stir. The smoke-test agent walked this path, and the signs aligned: GitHub was seen, the forge built cleanly, and the trace was left in the sands. Warning Firewall blocked 12 domainsThe following domains were blocked by the firewall during workflow execution:

📊 Test Coverage Report — 2026-09-25
Overall Coverage
The gh-aw-firewall codebase has achieved strong overall test coverage:
Baseline: 18,650 total statements across 2,858 functions; 17,032 statements covered.
🛡️ Security-Critical Path Status
Core security modules show strong to excellent coverage:
Finding: Network isolation (iptables) and domain filtering (squid-config) are fully tested. CLI entry point has medium branch coverage but acceptable statement coverage.
📋 Coverage Table
Critical Gap Areas:
src/nvx/cleanup-registry.tssrc/bounded-execution/finite-cardinality.tssrc/bounded-execution/finite-schema.tssrc/microvm/network-reservation.tssrc/bounded-execution/finite-disclosure.tsExceptions: These modules handle advanced features (NVX registry cleanup, bounded execution constraints, Cloud Hypervisor microVM networking) and are not security-critical for core firewall function, but branch coverage indicates complex conditional logic with gaps.
Excellent Coverage (90%+):
🔧 Function Audit
100% Coverage (43+ files):

📅 Recent Source Changes (last 7 days)
Pre-computed coverage data reflects current
HEADstate (2026-09-25 02:06 UTC). No uncommitted changes detected in security-critical files. All main firewall components have stable, high coverage with no recent regressions.🔎 Notable Findings
Network Isolation is Comprehensively Tested — All iptables rule generation (
host-iptables-rules.ts,host-iptables-chain.ts) and cleanup paths achieve 100% statement and branch coverage. This is the security-critical audit trail and is fully validated.Domain Filtering Coverage is Solid — Squid configuration generation (
squid-config.ts) and domain pattern matching (domain-patterns.ts,domain-matchers.ts) show 98–100% statement coverage. The 89.47% branch coverage indomain-patterns.tsreflects a single uncovered edge case (likely rare validation scenario).Critical Gap in NVX Cleanup Registry —
src/nvx/cleanup-registry.ts(24,433 LOC) has only 42.8% statement and 32.11% branch coverage. This file manages microVM artifact cleanup; while not core to the firewall's HTTP/HTTPS filtering, it represents a potential reliability gap for long-running NVX enclave workloads.Bounded Execution Tests Incomplete —
finite-cardinality.ts(46%),finite-schema.ts(49%), andfinite-disclosure.ts(52%) handle resource constraints and disclosure prevention. These features enable safe multi-step AI agent reasoning but have moderate gaps. The 11.42% branch coverage infinite-disclosure.tsis particularly notable—suggests critical paths lack conditional branch testing.🎯 Recommendations
🔴 HIGH Priority (1-2 weeks)
Increase
finite-disclosure.tsbranch coverage — Currently only 11.42% of branches covered. Add test cases for all conditional branches in disclosure sanitization logic. This directly impacts AI agent safety when returning structured data with sensitive fields.Close gaps in
nvx/cleanup-registry.ts— Improve from 42.8% to 80%+ statements. Focus on error paths, retry logic, and edge cases in registry cleanup. Add test vectors for container removal failures and orphaned artifact scenarios.🟡 MEDIUM Priority (2-4 weeks)
3. Expand
finite-cardinality.tsandfinite-schema.tscoverage — Move both from ~46–49% to 75%+ by testing cardinality constraint violations, schema edge cases, and validation error paths.No immediate action needed on core firewall paths (
host-iptables-*,squid-config-*,domain-*) — these are fully tested and production-ready.All reactions
