Gap analysis — c1 in decision #419
scry-mcdc · lib.rs:137 · branch 2890
Status: GAP
What you need
To prove condition c1 independently affects the decision, you need a row where c1 = T and the outcome differs from row 17437 (where c1 = F).
Required condition vector:
c0 = * c1 = 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_d419_c1() {
// Verdict: scry-mcdc
// Source: lib.rs:137
// Branch: 2890
//
// TODO: drive the function so condition c1 evaluates to the
// value above and the resulting decision outcome differs from
// the existing pair row.
todo!("witness viz: gap drill-down for d#419/c1");
}
After adding the test, re-run: witness instrument && witness run --invoke run_row_NEW && witness report. The condition should flip from gap to proved.
