Design Constructible Fire Berms

Goal

Design constructible fire berms or firebreak barriers as a tactical spread-control tool.

Why

Berms are simpler than fans and fit the simulation as spread resistance or spread blocking. They also give players a readable way to plan controlled burns and settlement defense.

Requirements

• Define whether berms fully block fire spread, reduce spread probability, increase heat loss, or combine those effects.
• Define construction materials and whether the berm itself is non-burnable.
• Define allowed placement rules, height behavior, and interactions with paths, buildings, and vegetation.
• Define whether berms block smoke or only fire spread.
• Define telemetry for berm cells, blocked spread attempts, and heat loss effects.
• Identify implementation tickets if the design becomes release-scope.
• Link back to Design Faction Fire Response Systems #53 in notes when the design is reconciled.

Dependencies

• Deferred child of Design Faction Fire Response Systems #53.

Role

• Researcher.
• Follow researcher.md.

Verification

• Run git diff --check.
