This is the full project page body — worth being thorough here since Modrinth wants an honest, clear explanation of what it does and how. Here's a draft (well over 200 characters):

# OSC Fire Control
A client-side firing-solution calculator for the OSC siege cannon (Mk6/MS).
Enter the origin coordinates, the target coordinates, and your passcode, and
the mod computes the firing solution and displays the Binary Output signal
you need to send to the cannon's control system.
## Features
- Simple, focused calculator UI — no clutter, no extra tabs
- Fully client-side: no server-side component, no permissions or op level required
- Nothing is sent to the server or visible to other players — it's just a
local math tool
- Open the calculator anytime with a keybind (default: **P**, rebindable in
Controls settings)
## Requirements
- Fabric Loader
- Fabric API
- Minecraft 26.2
## Notes
This mod does **not** place, spawn, or control any cannon itself — it only
computes the signal value. You still need a compatible OSC cannon setup
(e.g. built with command blocks / redstone / a datapack) to actually use the
output.
