# js/physics/damage/ — agents.md
Part of the modularization pass. Module map: `MODULES.md`; runtime model: `architecture.md`.

Installs into `P`: damageBlock, damageEnemy.

- Central damage accounting: material break points (with the wood/ice/stone hp
  ladder from constants.MATERIALS) and enemy hp floors. Score and stats counters
  (`stats.destroyedBlocks`, `stats.destroyedEnemies`, scorePopups) are minted
  here.
- The balance spec (`test/balance.test.mjs`) asserts per-material break budgets
  and enemy kill budgets under full-power direct hits — that spec is the
  contract for everything that deals damage. Falling-object
  impact damage) routes through these two functions so it inherits the spec.
- Consumes: MATERIALS, ENEMY_TYPES.
