nc_php.sh was the next-hardest library on the allowlist. It targets a Debian Raspberry Pi -- it edits /etc/php/<ver>/apache2/php.ini, drives occ as www-data and installs a crontab -- so none of its write targets exist on this Arch host and the jail had nothing to mirror. - --seed-dir / --seed-file create the paths a foreign-platform subject expects. Verified with a probe: /etc/php/8.2/apache2 exists inside the jail while /etc/php does not exist outside it. - A failed bind is now FATAL, and missing mountpoints are created first. A bind that fails silently is indistinguishable from unreachable code in the report, which is the misdiagnosis this runner exists to prevent. - Mirroring skips unreadable targets (/root as a normal user) rather than aborting under set -e. nc_php.sh: 84/85 = 98.82%, 24 assertions. It STAYS on the allowlist, because 98.82% is below the bar. Line 111 -- the crontab first-run fallback -- hung the suite on both attempts to cover it, so it is left uncovered and documented rather than tried a third time. Two harness hazards found the hard way and written down: a top-level stub function shadows the subject's own function for every later assertion (this silently dropped coverage 83.53% -> 57.65% while the tests still passed), and a stub for a piped-into command must drain stdin or the writer takes SIGPIPE. dot_resolver_install.sh still measures 39/39 = 100.00%.

"title": "Cover nc_php.sh and teach the jail runner to measure foreign-platform subjects",

"objective": "Extend the namespace-jail runner with the path seeding and bind-failure handling needed to measure a library written for another distribution, and use it to bring nc_php.sh -- the next-hardest library on the allowlist -- as close to the 100% bar as its code allows.",

|
"nc_php.sh measures at least 98% through its new suite, run inside the jail with the documented binds and seeds.",

"dot_resolver_install.sh still measures 39/39 = 100.00% after every runner change, proving no regression.",
|
|
"A bind-mount that cannot be established fails the run instead of warning, so a silent bind failure can never be reported as unreachable code.",

"shellcheck is clean on every new and modified file, with no suppression added.",
|

"The real /etc, /var and /root are unmodified after every run; the jail's escape assertion stays armed."
