Highlights

Restores shears-based tripwire disarming and supported hook-to-hook string farms
Supports pistonless, lever-controlled builds
Event-driven and bounded: no permanent world or chunk scan
English by default, with automatic German, French, and Spanish player messages
Live enable/disable, personal sound controls, and safe reload commands
No telemetry, network requests, NMS, reflection, or dependencies

Commands

Code (Text):

/stringduper on|off|status
/stringduper sounds [on|off]
/stringduper sounds status
/stringduper reload

Personal sound on/off commands are available to every player and only affect that player. Mechanic controls, reload, and both status commands require

Code (Text):

stringduper.admin

(OP by default).

Compatibility
One JAR supports Minecraft 1.21.2 through 26.3 on Paper-compatible servers. It is compiled against Paper API 1.21.1 for 1.21.2-compatible forks. Mojang fixed native tripwire string duplication in Java 1.21.2, but Paper skipped that server line, so direct official Paper boot tests start with 1.21.3. Java 21 or newer is required for 1.21.x; the 26.x server lines require Java 25 or newer.

Commands

/stringduper — Controls personal farm sounds and, for admins, the live mechanic.
/stringduper <on|off|status|sounds|reload> [on|off|status]
