Compatibility

Main channel detection

• Target range: roughly 1.8 – 1.21.11+
• Spigot / Paper / Purpur / Folia / PandaSpigot, etc.
• Folia is handled via a compatible scheduler adapter

Sign translation detection

Environment	Expectation
Paper 1.21.5+	Available (openVirtualSign)
Paper ≤ 1.21.4	Unavailable, skipped automatically
Some Paper forks	Depends on whether they track upstream API
Spigot	Usually no API, skipped automatically

Missing API does not break the plugin — only this module is disabled.

Soft dependencies

Plugin	Effect
PacketEvents	Earlier interception of channel registration when enabled
floodgate	skip-bedrock-via-floodgate can skip Bedrock for sign detection
LuckPerms / PlaceholderAPI	Permissions / placeholders ecosystem as needed
