Records where every item came from and shows it in the item's tooltip.

Open a chest and you get loot with no story. Chest DNA fixes that: the moment an item is created it gets an origin stamped onto it, and that stamp travels with the item for the rest of its life.

## What it does

Whenever an item enters the world - looted from a chest, dropped by a mob, bought from a villager, fished up, crafted, smelted or mined - Chest DNA attaches an origin to it containing:

Source - village, dungeon, End City, ancient city, mob, trade, workbench, … Detail - the loot table it rolled from, or the entity that dropped it Biome and dimension it came from Coordinates of the exact spot Structure it was found inside, when there is one Who obtained it, by name

This is stored as a real data component, so it survives world saves, shulker boxes, ender chests and multiplayer - and it is readable by commands, datapacks and other mods.

## What it looks like

Hovering the item draws a pixel-art card under the normal tooltip, drawn one pixel at a time with no textures, so it stays crisp at every GUI scale:

source name on top, tier stamped underneath frame colour by rarity - grey for a village chest, gold with shimmer pixels crawling around the border for an End City, an ancient city or an ominous vault an animated DNA helix down the left edge one glance by default; hold Shift for biome, dimension, coordinates and finder ids are shown only with advanced tooltips (F3+H), like vanilla

The card sizes itself against the screen: long values wrap, it never grows wider or taller than it has to, and it reports its real size so the tooltip always stays on screen.

## Sources it recognises

| Group |Covered | | ---------------- |------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | Structure chests |village, dungeon, mineshaft, stronghold, nether fortress, bastion, End City, ancient city, woodland mansion, trial chambers, ominous vaults, shipwreck, buried treasure, desert pyramid, jungle temple, igloo, ruined portal, pillager outpost, ocean ruins, bonus chest | | Creatures |mob drops, boss drops, shearing, cat and sniffer gifts, hero of the village | | Player actions |crafting, smelting, villager and wandering trader trades, fishing, archaeology, creative menu | | Mining |every block you break |

36 origin types in total, each with its own name, glyph and rarity tier.

## It does not get in your way

Stacking is unchanged. Two items that differ only in their DNA still stack exactly like vanilla, so a looted cobblestone does not fragment your inventory. The first source wins. An item is stamped once, when it is created, and never overwritten. * Cheap. One component write per generated item; the structure lookup is skipp
