**Note on syntax:** these files are RON, not JSON. The shapes below are exact,
but punctuation follows RON — read a real `data/*.ron` file alongside.

## Fields

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `class` | `string` | required | The item class this profile covers ("weapon"/"armor"/"tool"/"lock"/"good"). |
| `tiers` | `TierEffects[]` | required | All seven tier effects, in ladder order. |

## Nested shapes

### QualityTier

The seven quality tiers (semantic — engine code branches on it).

`Trash`, `Poor`, `Normal`, `Good`, `Excellent`, `Masterwork`, `Legendary`

### TierEffects

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `ac_delta` | `integer` | optional | AC delta at this tier (armor); absent = n/a. |
| `attack_delta` | `integer` | optional | Attack-roll delta at this tier (weapons); absent = n/a. |
| `damage_delta` | `integer` | optional | Damage delta at this tier (weapons); absent = n/a. |
| `dc_delta` | `integer` | optional | Lock DC delta vs the Normal DC 10 base at this tier (locks); absent = n/a. |
| `integrity_factor` | `number` | optional | Max-integrity multiplier (the `structure` class) — defaulted so the arms/tool/lock profiles never spell it. |
| `tier` | `QualityTier` | required | The quality tier this row describes. |
| `value_factor` | `double` | required | Worth multiplier at this tier (every class). |
| `work_factor` | `number` | optional | Work-output multiplier at this tier (tools); absent = n/a. |
