Carpet AMS Addition Legacy
Carpet AMS Addition Legacy extends the Carpet mod with rules that detect microtiming bugs in machines, with an undo operation for fixes.
What it does
The mod targets Minecraft 1.14.4 – 1.15.2 and requires Carpet on Fabric. Its main purpose is to detect microtiming bugs in redstone machines and offer an undo step when a change goes wrong. Several of its rules are kept as legacy versions of the newer Carpet AMS Addition line, so players on these older builds can still use them.
Installation is only needed on the side that uses the rules. Either a client alone, a server alone or both can run it, and neither side needs it. Files are published for Fabric under the GNU Lesser General Public License v3.0 only, and the project is open source with public source code, an issue tracker and a wiki. The developer notes that some rules from the main project were not carried over into this list.
Key features
Microtiming bug detection
Rules check redstone machines for microtiming problems, so a builder can see where a circuit depends on timing.
Undo operation
A change made to a machine can be reversed, which makes testing timing fixes less risky.
Legacy rule set
Rules that match the older Carpet AMS Addition line are kept here, for players who stay on 1.14.4 or 1.15.2.
Public development
The source is on GitHub, where feature requests and issues are tracked against the project.

Use cases
Debugging redstone clocks
A builder checks a timing-sensitive circuit and uses the undo step to test alternatives without rebuilding it.
Who it’s for: Redstone builders and map makers working on 1.14.4 or 1.15.2 who need timing checks, and server owners who want those rules on a multiplayer world.
How it compares
Carpet TIS Addition is also open source under the GNU Lesser General Public License v3.0 only, covers 1.14.4 – 26.3 and works on either side, with neither side required. Carpet CuO Addition is server-side only under the MIT License and covers 1.20 – 26.3, so clients need nothing installed.
