Krzysztof kuhy Rudnicki 578c4a6cdd Drop the 100% shell coverage bar; back to a presence ratchet
bca70b67 (2026-08-22) turned the shell ratchet from "a run_all.sh exists
beside this lib" into a measured 100% line-coverage bar, run through the
kcov+userns jail. It works -- dot_resolver_install.sh really does measure
39/39 -- but the price is one hand-written test file per lib: fixes/lib
took 34 test files for 22 libs, the jail runs serially at 37-90s a pass
(concurrent jails give false failures), and most libs need a production
seam added before they can be driven at all.

That put the remaining 84 exempt libs at several days of work, for a
repo of personal automation scripts. User's call today: not worth it.

python_pkg keeps its 100% branch bar, which is already met -- 2101 tests,
100.00%, zero missing statements or branches. The difference is the
instrument: pytest-cov is fast, reliable and parallel; the shell jail is
none of those.

Also tried and rejected, recorded in the file: a middle option where the
suite must MENTION the lib by name, closing the empty-suite hole the
100% bar was reaching for. It newly BLOCKED 68 libs sitting in
directories that already have suites -- 38 in utils/lib alone -- because
those passed the old presence check and so were never allowlisted, and
seed_allowlist refuses to grow by design. Tightening a ratchet with no
way to grandfather the existing tree turns it into a wall.

The jail is not deleted; it is still the tool for measuring a lib on
purpose, and ci_mirror.sh still runs jailed suites.

  check_shell_coverage.sh --all:  >600s  ->  0.31s
  BLOCK entries:                  3, all pre-existing meta/scripts/lib
                                  coverage-tooling libs
  allowlist:                      unchanged at 84 (--seed correctly
                                  refused to add the 3)
