Gap analysis — c5 in decision #80
scry-mcdc · library/core/src/slice/cmp.rs:442 · branch 564
Status: GAP
What you need
To prove condition c5 independently affects the decision, you need a row where c5 = T and the outcome differs from row 40299 (where c5 = F).
Required condition vector:
c0 = F c1 = F c2 = F c3 = T c4 = F c5 = T
Conditions marked * were short-circuited in the baseline row; the new test must drive inputs so they get evaluated to either T or F.
Suggested test stub
#[test]
fn closes_gap_d80_c5() {
// Verdict: scry-mcdc
// Source: library/core/src/slice/cmp.rs:442
// Branch: 564
//
// TODO: drive the function so condition c5 evaluates to the
// value above and the resulting decision outcome differs from
// the existing pair row.
todo!("witness viz: gap drill-down for d#80/c5");
}
After adding the test, re-run: witness instrument && witness run --invoke run_row_NEW && witness report. The condition should flip from gap to proved.
