Difficulty design

Difficulty is a versioned project policy, not a fixed ordering of knobs.

Contract

Publish:

• stable difficulty_policy_id and revision
• named mode/scaling policy
• affected systems and excluded systems
• measurement context: build, segment, player cohort or test mode
• challenge metrics and guardrails
• transition/switch rules, including whether mid-session changes are allowed
• evidence required to accept a tuning change

Possible levers include space, information, resources, enemy composition, timing windows, numbers, assists, checkpoints or other project-defined systems. Their order and use depend on the game.
