MIR4 Codex registration: the item disappears, so check before confirming
MIR4’s official Codex guide says registered items disappear. Registration exchanges the item for the entry’s benefit; it is not simply an inventory bookmark. Inspect the required item and the benefit before confirming a valuable copy.

Match the item to the entry
Open Menu → Codex and read the selected requirement. The official guide distinguishes Codex, Reputation Codex and Collection Codex. Confirm which entry you are completing, then check whether the selected item is one you still need for another purpose.
Read who receives the benefit and for how long
The guide distinguishes a server Codex from character effects and warns that limited-time Codices apply only for a specified period. Read scope and expiry together. Do not compare a temporary event entry with a lasting character improvement as though their labels meant the same thing.
Make the trade explicit
Illustrative decision: you have one spare item and an entry offering a stat you rarely use. Compare keeping that copy with consuming it for this specific benefit. If the item is needed elsewhere, leave the entry incomplete until you have made that trade deliberately. No registration is required just to inspect the requirement.
When your plan breaks
| What happens | What to change |
|---|---|
| An item vanished after registration | The official guide documents consumption. Check the completed entry. |
| A bonus later disappeared | Inspect whether the Codex was limited-time. |
| Another character does not show the expected bonus | Check whether that entry is server-scoped or character-scoped. |
Quick answers
Does the Codex keep a registered item in inventory?
No. The official guide says registered items disappear.
