# E2 (extra-spec): leading zeros rejected. "00" is non-canonical → ineligible.
# Eligible key: "0" only. Impl test: getList("items") returns ["b"].
# Lightbend behaviour: HashMap collision (both "00" and "0" parse to 0); winning value depends
# on iteration order — non-deterministic. Documented in expected/.../na08-leading-zero.divergence.md.
items = {"00":"a","0":"b"}
