ItemIntegrity ServerOnly

ItemIntegrity.ServerOnly

Server-only world cleaner for Valheim. No client installation is required.

This binary package contains ItemIntegrity.ServerOnly 0.2.0-preview.1, package version 0.2.0. It is an independent implementation, not

an official Ageous27-NoCheatItems release.

Preview limitations: This build does not scan or remove items in a player's

carried/equipped inventory on joining. Container and stand removal is deferred

until every player has disconnected. Dry-run is enabled by default.

What it cleans

| Location | Behavior |

| --- | --- |

| Ground drops | Scans serialized server world records, including records without a locally instantiated Unity object. When deletion is enabled, backs up matches, requests native network destruction, and checks server-record disappearance. |

| Chests, carts, ships, and tombstones | Scans native container inventories. Removal waits until the server has been empty for at least 15 seconds, with additional stable-record checks for serialized edits. |

| Item and armor stands | Checks attached item flags and prohibited prefab names. Removes the attachment, not the stand, during the same empty-server maintenance window. |

Default detection covers the native cheated-item flag and the debug prefabs

SwordCheat and SledgeCheat. Additional exact prefab names can be configured.

An extra-prefab rule also matches legitimate copies of the named item.

What it does not do

It does not clean a player's bag on connection, force players to drop their

inventory, kill or disconnect them to expose inventory, or require a client mod.

It does not edit offline character saves or unloaded save chunks, undo character

achievement/cheat status, or remove overstacked/over-quality items. Unknown custom

storage and unsupported or malformed serialized data are skipped. It is not a

complete anti-cheat or inventory-import prevention system.

Install

Install on the dedicated server only. Back up the world and use a test copy

before enabling actual removal. Do not run this cleaner alongside the original

NoCheatItems or the earlier client-required ItemIntegrity.

• Ensure BepInExPack Valheim is installed on the server. The manifest declares

denikson-BepInExPack_Valheim-5.4.2350.

• Stop the server and disable the previous cleaner through its mod manager so it

is not automatically restored. Keep old cleaner DLLs outside the entire active

BepInEx/plugins tree.

• For a manager that supports local ZIP packages, import this ZIP

into the server installation. For manual installation, copy

ItemIntegrity.ServerOnly.dll into BepInEx/plugins/ItemIntegrity.ServerOnly.

• Start the server to generate

BepInEx/config/local.valheim.itemintegrity.serveronly.cfg.

No existing configuration is included or overwritten by this package. The plugin

uses a new config identity and does not import ageous27.nocheatitems.cfg.

DryRun = true logs matches without removing them. After validating detection

on backed-up test data, stop the server and change the generated configuration:

[General]

Enabled = true

DryRun = false

Restart the server. Container and stand removal still requires all players to

leave; the 15-second grace is a minimum, not a promise of removal at exactly 15

seconds. Sweep length, stable observations, and edit limits can add delay. Keep

ExtraPrefabNames empty for native cheated-flag detection; listing Wood would

also prohibit legitimate Wood.
