Gap analysis — c7 in decision #1342
scry-mcdc · library/alloc/src/collections/btree/node.rs:731 · branch 289
Status: DEAD
Condition is dead: the runtime never reached this branch under any test row. The compiler may have folded the predicate, or the call-path is unreachable from the harness.
Action: confirm by reading the source. If the branch is genuinely unreachable, the dead status is the verdict. If reachable, expand the test corpus to drive code through this branch.
