# Spending Profiles

Every minted companion has a spending profile: 12 category scores packed onchain into a `uint96`. The profile describes interests and helps determine skill co-ownership eligibility and revenue weighting.

## Canonical Packing Order

Do not reorder these categories in clients. The onchain packing order is:

| Index | Category      |
| ----: | ------------- |
|     0 | education     |
|     1 | entertainment |
|     2 | fashion       |
|     3 | finance       |
|     4 | food          |
|     5 | healthcare    |
|     6 | housing       |
|     7 | beauty        |
|     8 | reading       |
|     9 | social        |
|    10 | travel        |
|    11 | sports        |

Each value is stored in a 4-bit nibble and should be in the 1-10 range for normal app use.

## How Scores Are Used

Spending scores influence:

* Skill co-ownership eligibility.
* Revenue weights in skill ownership.
* OASF/domain metadata.
* Autonomous purchase preferences.
* Companion behavior and recommendations.

## Skill Co-Ownership Eligibility

To register a companion for a skill, the companion needs a sufficient score in the skill category. The current minimum is 5.

## Revenue Weight

Skill co-owner distribution weights are:

```
weight = BONZAI balance of companion wallet * profile score
```

This makes skill revenue depend on both economic stake and category fit.

## Updates

Companion owners can update spending profiles where the contract permits it, especially for bare companions that were minted before full personalization.

## UI vs Onchain Order

The UI can display categories in a friendlier order, but packing/unpacking must always use the canonical onchain order above.
