Sign Logger

Each sign edit is stored as an event with the author, the position and the world time. Four event types are kept: a waxed sign, a changed text, a dyed sign and a glowed sign. Changed text events hold the old and new text of each side of the sign, and the log view lets a player hover over a side to see the text before and after the edit. Dyed and glowed events record the old and new color or glow state of the affected side.

Operators with permissions can switch an inspection mode on or off with a command. While it is active, a left click on a block shows the sign-edit logs for that block's coordinates, and a right click shows the logs for the block on the adjacent face. Inspection mode turns off by itself when the player dies or leaves the server, so the player can still break and place blocks normally afterward.

Logs go into a simple database. Server owners can set how many days of logs to keep, purge older entries with a command, and have the database purged on shutdown using the configured limit. Logging to the console can be toggled in the mod's settings. The mod requires Fabric API, and it runs on the server alone, so players join without installing anything. Builds cover 1.20 – 1.20.4, and the latest file is 0.0.2-1.20+ for 1.20.4.
