## Record (`org.cairnsproto.draft.witness`)

Type: record · key tid

### Properties

- `amends` (ref): An earlier witness by the same author about the same stone.
  - Reference: `com.atproto.repo.strongRef`
- `createdAt` (string · datetime, required)
- `evidence` (union, required)
  - One of: `#checkResult`, `#judgment`, `#recall`, `#resolution`
- `stone` (ref, required)
  - Reference: `com.atproto.repo.strongRef`

## #checkResult (`org.cairnsproto.draft.witness#checkResult`)

Type: object

### Properties

- `check` (ref, required)
  - Reference: `com.atproto.repo.strongRef`
- `output` (ref, required): Hash of the check's canonical output bytes.
  - Reference: `org.cairnsproto.draft.defs#hash`

## #judgment (`org.cairnsproto.draft.witness#judgment`)

Type: object

A judge's verdict on a pinned prompt. Tallies like a read; never an anchor.

### Properties

- `prompt` (ref)
  - Reference: `org.cairnsproto.draft.defs#hash`
- `rationale` (string)
  - Constraints: maxLength: 30000, maxGraphemes: 10000
- `verdict` (string, required)
  - Constraints: maxLength: 32, knownValues: supports | refutes | unclear

## #recall (`org.cairnsproto.draft.witness#recall`)

Type: object

Flags a faulty method so every stone it produced is re-sampled. Intent-neutral.

### Properties

- `evidence` (array, required)
  - Constraints: minLength: 1, maxLength: 1000
  - `items` (ref)
    - Reference: `com.atproto.repo.strongRef`
- `method` (ref, required)
  - Reference: `org.cairnsproto.draft.defs#methodSelector`

## #resolution (`org.cairnsproto.draft.witness#resolution`)

Type: object

An escalated site's answer: a project maintainer or a member of the policy's escalation list endorses the witnessed stone's value. From one of them it counts as a passed anchor for that value, which ends the escalation.

### Properties

- `rationale` (string)
  - Constraints: maxLength: 30000, maxGraphemes: 10000
