Gap analysis — c9 in decision #393
scry-mcdc · lib.rs:6772 · branch 2566
Status: GAP
What you need
To prove condition c9 independently affects the decision, you need a row where c9 = T and the outcome differs from row 223166 (where c9 = F).
Required condition vector:
c0 = F c1 = F c2 = F c3 = F c4 = F c5 = F c6 = F c7 = F c8 = F c9 = T c10 = F c11 = F
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_d393_c9() {
// Verdict: scry-mcdc
// Source: lib.rs:6772
// Branch: 2566
//
// TODO: drive the function so condition c9 evaluates to the
// value above and the resulting decision outcome differs from
// the existing pair row.
todo!("witness viz: gap drill-down for d#393/c9");
}
After adding the test, re-run: witness instrument && witness run --invoke run_row_NEW && witness report. The condition should flip from gap to proved.
