SnDiscordLink v1.0.0

First stable release of SnDiscordLink.

Links Minecraft accounts to Discord accounts with one-time codes. Several servers share one
MySQL database and elect a single embedded Discord bot through a database lease, so a player
links once and every server, placeholder and reward follows.

Features

• One-time 6-digit codes in both directions: /discord link in game redeemed with /link <code>
  in Discord, and /link in Discord redeemed with /discord verify <code> in game.
• Multi-server by design: codes, links, rewards, cooldowns and the bot lease all live in the
  shared database. No cross-server messaging, identical config.yml everywhere.
• Automatic bot failover: exactly one backend holds the lease and runs JDA; a dead host is
  replaced in about 30 seconds.
• linked-role given on link and removed on unlink, with optional nickname sync.
• claims: in-game rewards gated by a boost or a Discord role, each with its own cooldown.
• rank-roles: permanent LuckPerms groups mirrored to Discord roles. Only mapped roles are
  ever added or removed, one PATCH per member.
• role-rewards: Discord roles that run on-gain / on-lose actions in game.
• rewards: action lists run once on link, on unlink and on a Discord leave.
• PlaceholderAPI expansion and a webhook embed log of link events.
• Discord side: /link, /unlink and the staff group /dlink info | unlink | accounts | stats.
