EMI: added 52 missing active helper-table exclusions; source-table previews retained.
Grand Library gameplay corrected to match approved previews: atlas and XP tome 3.7% each; lucky scarf and superstitious hat 2% each. Artifact nested tables retained.
No other gameplay changes.
Investigation: supplied EMI Loot 0.7.9 NeoForge JAR chest parser multiplies pool random_chance into display percentages. Golden Eggple pools have 5%, not 100%. Specific reported 100% entries not reproduced in a running Minecraft client.
