# Exact samples and item admission

> Understand complete item fingerprints, custom data, node consistency and special-item restrictions.

<h2 id="exact-samples-and-custom-items">
  Exact matching
</h2>

Exact mode retains serialized item data and compares complete properties, including the name, lore, enchantments, and serializable custom data.

Sample stack size does not define the order quantity or price. Changing durability, name, or other metadata can make an item stop matching.

## Sample storage and display

New exact buy orders retain both the real sample and rule fingerprint, validate admission and matching material/fingerprint when published, and normalize the sample quantity to one.

The sample is for display; fulfillment still transfers the supplier's actual items.

Historical orders containing only a fingerprint identify the missing display sample instead of guessing or recreating the original item.

## Custom items and node consistency

KiteMarket does not interpret third-party item IDs or equate items solely by appearance.

Nodes must have matching Minecraft versions and item profiles. Validate real samples created by your item plugin before enabling player trading.

## Item admission

Exact samples still must pass item admission and serialization round-trip checks. Exact mode cannot bypass these restrictions.

`1.0.0` does not accept new trades in items with nested storage structures, such as shulker boxes and bundles; empty shulker boxes are also excluded. Other special items or data can be traded only if admitted by the current build.

If you see `UNVERIFIED_SPECIAL_ITEM`, `UNVERIFIED_ITEM_DATA`, or `ITEM_ROUNDTRIP_UNSAFE`, stop listing that item instead of retrying in exact mode.
