# C×B×I

> Three orthogonal dimensions of interaction.

Every nuance in every Protocol carries a tag that places it on one of three dimensions. The tag is a coordinate, so nuances from different Protocols compose into the same space.

| Dimension          | What it reads                                               |
| ------------------ | ----------------------------------------------------------- |
| **C: Cognitive**   | Reasoning, structure, information processing, metacognition |
| **B: Behavioural** | Communication acts, observable patterns, stylistic stance   |
| **I: Intentional** | Goal orientation, motivation, agency expression             |

## Usage

C×B×I enables aggregation across Protocols. A population heatmap, an agent benchmarking suite, and a recruitment evaluation can all produce a single comparable C×B×I coordinates even when they use different Blueprints.

Each participant in an interaction accumulates a per-dimension score. For `n` actants, each interaction produces `n × 3` dimensional readings.
