• Priority: 3
• CLI: claude

Description

In src/lir/lower.ts around lines 638-642, the variable retSlot is declared but never used — the return_value instruction is emitted with srcSlot directly instead. Investigate whether retSlot should be used (i.e., the instruction should copy srcSlot into the $ret scoreboard slot explicitly) or whether the variable is a dead refactoring artifact and should be removed. Read the surrounding context and the emit stage handling of return_value instructions to determine the correct fix, then apply it.
