  "message": "fix: Add explicit type check in SumLocalStep and document local scope boxing semantics\n\nAdd an instanceof Number guard in SumLocalStep to deterministically reject non-numeric input on the single-element path, fixing a JIT-dependent type-erasure hole where sum(local) on a non-numeric scalar would sometimes pass through as identity instead of erroring.\n\nDocument the Scope.local boxing/wrapping contract in the semantics doc (scalars are coerced to single-element sequences) and add tests locking the behavior for sum, mean, min, and max local steps, plus the IteratorUtils singleton-wrapping contract.\n\nAssisted-by: Kiro:claude-opus-4 [kiro-cli]\n",
