AI Slop?

Well, technically yes. I used Codex to implement it. Don't like it - don't use it. No hard feelings. I thought the idea would be fun. I don't know and don't have time to learn lua - so here we are. Feel free to take the idea and implement it by yourself if that makes you and communitys life better.

2.1 version when? 0.2 and up when?

When it comes or when I find some time to test and update.

What does this mod do?

The first eligible structure of each type built by a force becomes a permanent historical First. Its identity can survive mining, transport, and rebuilding. Destroying or losing it does not promote a successor.

Does it change how structures work?

No. It does not add production or health bonuses. It preserves the original item name, stack size, recipes, quality, and damage. Ordinary items remain stackable.

Can a blueprint copy a First's identity?

No. Blueprint and copy-paste builds create ordinary structures. They do not copy the artifact ID.

What happens when a First is mined?

The authentic carrier keeps its identity. Rebuilding that item restores the same artifact and increments its placement count.

Can I place an artifact in another force?

No. FOHN rolls back the build and returns the item to inventory or cargo, or drops it nearby if there is no room.

Does it work on an existing save?

Prototypes already present when FOHN is added have unknown history and do not receive a First retroactively. New prototypes and forces can establish histories after monitoring begins.

What happens if an artifact is recycled?

In Factorio 2.0, recycling or other unexpected carrier destruction ends the artifact as lost/unknown. FOHN does not guess the cause, and products do not inherit its identity.

Which structures are supported?

FOHN discovers eligible static structures with an unambiguous item-to-entity relationship and a single mining result. Some modded structures may qualify, but compatibility with every mod is not guaranteed. Vehicles, rails and tiles, equipment, and custom multi-result build/mining cycles are outside the supported scope.

Which Factorio versions and expansions are supported?

The mod targets Factorio 2.0 and requires Base 2.0.77 or newer. It was verified on 2.0.77. Quality and Space Age are optional integrations. This does not guarantee compatibility with every mod combination.

What happens if I uninstall the mod?

If you save the game after fully uninstalling FOHN, the game removes its stored history. Reinstalling cannot recover it; restore a backup made before uninstalling.
