Rust tool cupboard upkeep: stop base decay

Rust tool cupboard upkeep is paid with the materials shown in the cupboard's inventory. Stock those materials and read its protected-time display; authorization alone does not fill it.

Check three things

1. Protect the cupboard and check who can access it.
2. Read the actual upkeep requirements and remaining protection in its panel.
3. Recheck after changing the building instead of relying on an old screenshot.

The developer's item data lists 1,000 wood to craft a cupboard. Its explanatory page says a separate, unconnected building needs its own upkeep arrangement. Building privilege also does not make a structure immune to every placement by an outsider.

Avoid stale formulas

The older explanatory wiki says high external walls do not add upkeep, but the September developer patch says high walls now have a 20% static upkeep cost. That conflict is why this guide does not copy the older page's entire cost model. Exact current group-tax brackets and every external-cupboard interaction remain UNSURE here.

Hizzle suggests checking protected time before ending a session and after an expansion. That is a planning habit, not a guarantee that upkeep prevents raids.
