What is reported to affect the rating?

The guides describe white skulls as positive for a grave and red skulls as negative. They also report that grave decorations or markers contribute, so body preparation and what you place at a plot can both matter. This shared description is still a community-guide report because neither source identifies a tested build. The exact arithmetic, category names, and whether every object contributes in the same way are pending confirmation.

Should every corpse go into a grave?

The launch-day guides distinguish a corpse prepared for burial from one considered for zombie use. They report that a body with stronger white-skull potential is more useful for a grave, while red-skull potential may matter for a zombie. Before making that choice, inspect the body and the current autopsy interface. Do not assume that a specific skull count guarantees a rating or worker result until the relationship is checked in your version.

How should you spend grave materials?

One guide advises matching decorations to the positive potential of the corpse instead of placing every available item on every plot. This is a useful resource-saving lead, but the source does not give a verified formula for deciding when an upgrade is worthwhile. The collected evidence does not confirm a universal rating target, bonus amount, or cheapest layout. Those values remain pending confirmation; this draft intentionally leaves them out.
