Discord Viper

Fixed on all three mods:

Advancement spam — the mixin fired on every award() call (including recipe/criterion grants with no display, hence "Unknown Advancement"). It now only fires when vanilla would actually announce: criterion newly granted + advancement complete + has display + shouldAnnounceChat(). Silent stuff is skipped silently, no log spam.(only affected moded instances)

Empty names — added a playerName() fallback chain (scoreboard → name → display name) and join/leave/death/advancement now skip instead of sending "** ** joined". Note: your log shows even vanilla printing " joined the game" with a blank name, so that test client is connecting with an empty username (offline-mode quirk) — real players will show normally.

Console forwarding — the 26.2 forwarder was a stub that never captured anything. It now attaches a real Log4j appender: lines accumulate in a buffer, flush to your console channel as soon as it hits ~1000 chars, plus a 15s flush for leftovers. Set consoleForwardChannelId in config and make sure forwardConsole: true.

Also fixed a latent 1.21 crash along the way (grantCriterion takes AdvancementEntry, not Advancement — would have blown up at runtime the same way the 26.x mixins did).
