【策划架构】Lua动态过滤：仓库装备的多条件组合筛选

    local out = {}
    for _, it in ipairs(items) do
        -- 写死组合：战士且强化5，别的组合查不了
        if it.job == "战士" and it.lv >= 5 then
            out[#out + 1] = it
        end
    end
    return out
end

local function match(it, c)
    if c.op == "==" then return it[c.k] == c.v end
    if c.op == ">=" then return it[c.k] >= c.v end
