Sibling of CALCITE-7731.
Bug: Primitive.checkOverflow calls BigDecimal.toPlainString on a value with scale < 0 without bounding the plain-notation expansion. A large negative scale can force toPlainString to materialize gigabytes and OOM, same pattern bounded elsewhere in CALCITE-7731.
Fix: Gate the toPlainString call with isBoundedDecimal. This mirrors SqlUtil.isBoundedDecimal in core but is inlined in linq4j to avoid a circular linq4j -> core dependency. The bound reads calcite.parser.maxDecimalLiteralPlainDigits (default 10000) and checks precision + abs(scale) <= limit. If exceeded, throw IllegalArgumentException before allocation.
Evidence: RED->GREEN verified. Both :linq4j:compileJava configurations succeed. Formatter blast radius is one file.
