Gap analysis — c3 in decision #1067

scry-mcdc · memories.rs:33 · branch 7497

Status: GAP

What you need

To prove condition c3 independently affects the decision, you need a row where c3 = T and the outcome differs from row 2190 (where c3 = F).

Required condition vector:

  c0 = F
  c1 = *
  c2 = *
  c3 = 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_d1067_c3() {
    // Verdict: scry-mcdc
    // Source: memories.rs:33
    // Branch:  7497
    //
    // TODO: drive the function so condition c3 evaluates to the
    // value above and the resulting decision outcome differs from
    // the existing pair row.
    todo!("witness viz: gap drill-down for d#1067/c3");
}

After adding the test, re-run: witness instrument && witness run --invoke run_row_NEW && witness report. The condition should flip from gap to proved.
