A lift is evidence about the shipping gate only if it executes the way the shipping gate executes. Every button here runs `set -euo pipefail`. Eighteen lift sites prefixed their driver with `set -uo pipefail` and no -e — four per fork (selftest-harness, selftest-scalar-statements, selftest-statements twice) and both accumulator lifts — while sixteen other sites got it right. The estate did it both ways, which is what made this a defect and not a convention. Without -e a failing command does not abort: execution continues and the driver returns the LAST command status. A lifted phase can therefore reach a verdict the shipping phase would never reach while the self-test reports the gate "works". selftest_statements.sh:27 claims the tested logic IS the shipping logic; in this respect it was not. NO VERDICT CHANGED. Every self-test that passed before passes now, at the same timings, so -e was not masking a false green at these commits. The defect was fidelity and the claim is no larger than that. The durable part is not the 18 edits. lift-guard.sh already inspects every driver, so it now REFUSES any lift whose driver does not enable errexit and prints the drivers actual shell options. Negative-tested four ways: no -e rejects, `set -euo` passes, bare `set -e` passes, no set line at all rejects. Byte-identical across the four forks. The nineteenth lift someone writes fails closed rather than silently testing a more permissive shell. Certified by the round-15 sweep: 50/50 GREEN, six repositories, both buttons and every self-test, exit 0. Registered and NOT fixed here: ltl-accumulator-verified has no lift-guard.sh at all and calls it zero times, so its two lifts remain unguarded — the one place this class can still recur silently.
