calculate consecutive numeric values, but it fails because of floating point numbers jq command

With a Json field like the one below, if eventId is a continuous value,I would like to add the value of the message field.

However, even if eventId is continuous, if the message field starts with # Time, the message field is separated.

This is the original field of Json.

{"events": [        {"message": "# Time: 1","eventId": "38636469249093328935961608873790523617989208925384015872"        },        {"message": ", 2, 3","eventId": "38636469249093328935961608873790523617989208925384015873"        },        {"message": "# Time: 11","eventId": "38636469249093328935961608873790523617989208925384015875"        },        {"message": "# Time: 12","eventId": "38636469249093328935961608873790523617989208925384015876"        },        {"message": "# Time: A","eventId": "1"        },        {"message": ", B, C","eventId": "2"        },        {"message": "# Time: C","eventId": "3"        },        {"message": "# Time: D","eventId": "5"        }    ]}

Here's what I want it to look like:

[  {"message": "# Time: 1, 2, 3"  },  {"message": "# Time: 11"  },  {"message": "# Time: 12"  },  {"message": "# Time: A , B, C"  },  {"message": "# Time: C"  },  {"message": "# Time: D"  }]

I've asked a question about this before and received an answer from a great person. (Thank you pmf.)
After this, I tried my best to refine it a little more, but it didn't work, so I asked once more.

First, When Ifirst run this JQ, I get the following results.

jq -r '.events | reduce .[1:][] as $i (.[:1];    if ((.[-1].eventId | tonumber + 1 | tostring) != $i.eventId) or ($i.message | startswith("# Time:")) then        . += [$i]    else        .[-1].message += " " + $i.message    end) | del(.[].eventId)'

[  {"message": "# Time: 1"  },  {"message": ", 2, 3"  },  {"message": "# Time: 11"  },  {"message": "# Time: 12"  },  {"message": "# Time: A , B, C"  },  {"message": "# Time: C"  },  {"message": "# Time: D"  }]

I saw it as a floating point issue and wanted to compare this number with the string itself, so I created a function as follows, but it did not work.

jq '# Function to add one to a large number represented as a stringdef add_one(num):  (num | split("") | reverse | map(tonumber)) as $digits  | reduce range(0; length) as $i ([];      . + if $i == 0 or .[-1] == 10 then            [($digits[$i] + 1) % 10]         else            [$digits[$i]]         end    )  | reverse | map(tostring) | join("");# Process events and check continuity.events | map(.eventId |= tostring) # Ensure all eventIds are strings| reduce .[1:][] as $i (.[:1];    if (add_one(.[-1].eventId) != $i.eventId) or ($i.message | startswith("# Time:")) then        . += [$i]    else        .[-1].message += " " + $i.message    end)| del(.[].eventId)'

[  {"message": "# Time: 1"  },  {"message": ", 2, 3"  },  {"message": "# Time: 11"  },  {"message": "# Time: 12"  },  {"message": "# Time: A"  },  {"message": ", B, C"  },  {"message": "# Time: C"  },  {"message": "# Time: D"  }]

As I searched further, I found a command called gojq, but I would like to test it first to see if it is possible with jq.

I am using jq version 1.7.1.
