### The Breakout contract now measures how well a run played, not that it played

Expand All @@ -24,6 +24,8 @@ All notable changes to Playproof are documented here.
- **`ale.test.mts` keeps a demonstration contract** derived from the same reference, with the two hash tiers, a `requires` chain and `life-lost`. The screen-frame and save-file evidence tiers, the opaque-collision sweep, the attrition classifier and the collapse gate stay under test on the real emulator; they are simply no longer things a Breakout player is graded on. `screen-blind` joins the two steering controls as a permanent gate, and the test now asserts the strongest control does NOT reach the top rung.
- **What a consumer must do.** The packaged reference file, the derived contract and its hash all change. A stored `Attestation` or `EpisodeRecord` against the old contract does not verify against the new one, and a milestone id from it (`score-opened`, `score-tier-2`, `score-tier-4`, `life-lost`, `frame-at-first-score`, `save-at-first-score`) no longer exists. Pass the previous reference through `makeAle({ game: 'breakout', reference })` to keep the old contract. No adapter behaviour changed: the worker, the evidence keys, the observation, the input vocabulary and the seed handling are untouched.

## 0.8.0

### A milestone earned by dying is not evidence of skill

- **The measurement.** ALE Breakout, ale-py 0.12.1, seed 0. Two deterministic controls with the same control law and the same deadzone in screen pixels, differing only in what they read: the ASCII frame at four screen pixels per character, or the `ram_ball_x`/`ram_paddle_x` channels at one pixel each. Neither carries state between decisions and neither costs a model call.
