🔍 Notable Findings

• src/cli.ts entry-point has only 50% branch coverage: the require.main === module guard that invokes program.parse() is never exercised by the test suite, meaning the real CLI bootstrap path is completely untested.
• Branches are the weakest metric overall (94% vs. 99.53% functions / 98.28% lines): the largest gaps are in src/config-writer.ts (branches 78.94%), src/workdir-setup.ts (79.62%), src/ssl-bump.ts (83.33%), and src/commands/logs-command-helpers.ts (83.33%) — all covering error and defensive-guard paths.
• Security-critical host-iptables-chain.ts has one uncovered error branch (90%): the isMissingIptablesError throw path is never tested, leaving the "fail-closed vs. fail-open" behavior of the firewall unverified in the error case.
• domain-patterns.ts has 2 uncovered branches (89.47%): these lie in the domain validation/matching logic that drives Squid ACL decisions; any regression here could silently allow unintended egress.

📌 Recommendations

[High] Cover the CLI bootstrap path in src/cli.ts
The require.main === module guard and the program.parse() call are never executed during tests (branch coverage 50%). Add a test that spawns the CLI as a child process (or mocks require.main) to exercise the real entry path. This is the first line of defense for argument handling and security flag wiring.

[High] Add defensive-branch tests for src/config-writer.ts and src/workdir-setup.ts
Both files guard against symlink attacks (isSymbolicLink() → throw) and non-directory paths (isDirectory() → throw), and config-writer.ts also has the seccomp-profile embedded-write path entirely untested. These guards protect against filesystem manipulation; bringing both files from ~79% to ≥90% branch coverage would close the largest remaining gaps.

[Medium] Test iptables error propagation in src/host-iptables-chain.ts
The isMissingIptablesError throw branch (the one that converts a low-level error into a user-friendly "iptables is required" message) is not covered. A single unit test that injects a mock iptables-missing error would cover this path and verify the firewall fails safely rather than silently.
