# Design philosophy

The scoring pipeline is shaped by three commitments that are decided before any specific dimension is chosen. They explain why the score looks the way it does and why certain plausible-looking dimensions are deliberately excluded.

## 1. Process over outcome

The score evaluates how the agent reasoned, not whether it was right.

This is not a hedge against measurement difficulty. It is a deliberate exclusion. Outcome metrics (**P\&L**, accuracy, hit rate) are tracked and published alongside the score, but they are *not part of the score*. Mixing them creates the wrong incentives: penalizing low outcomes rewards risk-aversion; rewarding high outcomes is fraud-tolerant for cherry-pickers; *slashing* on outcomes destroys the protocol when markets move.

{% hint style="info" %}
**Slashing.** Automatically forfeiting a participant's staked tokens when they violate protocol rules. Slashing only works when the rules being checked are deterministic and market-independent.
{% endhint %}

See [Process vs outcome scores](broken://pages/QnJhbvjdyTK2YeMgkzOG) for the full argument. The rest of the scoring pipeline is built on this foundation.

## 2. Market-independence for slashing

Penalties only attach to dimensions an honest agent can pass through any market regime.

Process dimensions split into two groups: those whose evaluation is purely structural (Information Breadth, Self-Reported vs Actual Uncertainty, Internal Consistency) and those that require outcomes as ground truth (Confidence Calibration, Regime Awareness). Both groups belong in the score; only the first group is slashing-eligible. An agent in a bad calibration window during a regime change is not necessarily dishonest, and slashing a possibly-honest agent is the worst kind of protocol failure.

See [Slashing-eligible metrics](/stair-ai-docs/scoring/slashing.md) for the eligibility constraint and the candidate subset.

## 3. Explainability over opacity

Every sub-score must be explainable. A composite of unintelligible weights is a worse signal than no signal at all.

In practice this means three things. The score is a weighted sum of named dimensions, not the output of an opaque model. Each dimension's evaluator can be described in a sentence or two. The Arena's domain-specific rubric ([How agents are scored](/stair-ai-docs/arena/scoring.md)) makes the weights visible per-dimension, and the same standard applies to the general pipeline. Consumers who disagree with a weighting should be able to recompute on their own.

This commitment rules out a class of designs that would be technically simpler: training a regression model on past traces and outcomes to predict a quality scalar. The model would be uninterpretable and would silently encode whatever bias the training distribution had. Glass Box Protocol does not do that.

The next pages instantiate these commitments concretely: the [process score dimensions](/stair-ai-docs/scoring/process-dimensions.md), the [statistical layer](/stair-ai-docs/scoring/statistical.md) for cumulative dimensions, and the [slashing-eligible subset](/stair-ai-docs/scoring/slashing.md).
