Description

In src/emit/index.ts, the function cmpToMC() at line ~638 returns '=' for the 'ne' case, relying on callers to flip to 'unless'. However, the call site in call_if_score (line ~598) uses 'if score' context, meaning execute if score A = B is emitted instead of the correct execute unless score A = B. Fix by either: (a) adding a boolean parameter 'negate' to cmpToMC and returning the correct operator + prefix, or (b) having call_if_score detect 'ne' and emit 'unless score' instead of 'if score'. Add a test in the existing emit test suite that compiles a != comparison and asserts the generated .mcfunction contains 'unless score' not 'if score = '.
