kcov works here once invoked correctly, so shell coverage is measurable after all. shell_coverage.sh wraps it as a gate; the XML parsing lives in shell_coverage_report.py per the rule against inlining another language's logic in a shell script. Two kcov traps are documented in the wrapper because both fail silently. It must be handed the test script DIRECTLY: given `bash script.sh` it instruments the bash binary, finds no shell source, and reports 0/0 at 0.00% -- indistinguishable from "nothing is covered". And per-line detail exists only in cov.xml; coverage.json carries the percentage alone, so it cannot say which lines are missing. First measurement put dns_iptables.sh at 68/74 = 91.89%, with all six uncovered lines in error and edge branches: chain creation failing, jump insertion failing, the stale-jump de-dupe log, and the v6 trusted-resolver ACCEPT. The stub grew failure injection and jump seeding to reach them, and four new cases take it to 74/74 = 100.00%. The gate fails closed: deleting the three ensure_chain failure cases drops it to 93.24%, names lines 23, 24, 37, 40, 41, and exits 1. Not wired into pre-commit -- kcov is absent on CI, and most shell files here have no test at all.
