Gap analysis — c0 in decision #1467

scry-mcdc · panicking.rs:434 · branch 9663

Status: GAP

What you need

To prove condition c0 independently affects the decision, you need a row where c0 = T and the outcome differs from row 48402 (where c0 = F).

Required condition vector:

  c0 = T
  c1 = *
  c2 = *
  c3 = *
  c4 = *
  c5 = *

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_d1467_c0() {
    // Verdict: scry-mcdc
    // Source: panicking.rs:434
    // Branch:  9663
    //
    // TODO: drive the function so condition c0 evaluates to the
    // value above and the resulting decision outcome differs from
    // the existing pair row.
    todo!("witness viz: gap drill-down for d#1467/c0");
}

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