Gap analysis — c6 in decision #0

scry-mcdc · lib.rs:232 · branch 6

Status: GAP

What you need

To prove condition c6 independently affects the decision, you need a row where c6 = F and the outcome differs from row 7479 (where c6 = T).

Required condition vector:

  c0 = *
  c1 = F
  c2 = T
  c3 = *
  c4 = *
  c5 = F
  c6 = F
  c7 = *
  c8 = *
  c9 = *

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_d0_c6() {
    // Verdict: scry-mcdc
    // Source: lib.rs:232
    // Branch:  6
    //
    // TODO: drive the function so condition c6 evaluates to the
    // value above and the resulting decision outcome differs from
    // the existing pair row.
    todo!("witness viz: gap drill-down for d#0/c6");
}

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