# ConceptAnchor

Pinning meaning to immutable references

Layer: Infrastructure · Category: Data Structures

## Mechanism

Agents do not define terms inline; they reference immutable, content-addressed 'Concept Anchors' stored globally. 'I want [hash:Apple]', not 'I want an apple'. It is established via an external drop event that finalizes the definition hash.

## Invariants

- Immutability: The definition pointed to by the Anchor Hash cannot change.
- Resolution: The Anchor must resolve to a valid schema or content.

## Failure modes

- Link rot (if anchors disappear).

## Data schema

```json
{
  "type": "object",
  "required": [
    "definition_hash"
  ],
  "properties": {
    "definition_hash": {
      "type": "string",
      "description": "Content-addressed hash of the anchored definition"
    },
    "content": {
      "description": "The actual definition content - any valid JSON (schema, text, or structured data)"
    },
    "metadata": {
      "type": "object",
      "description": "Optional metadata (creator, timestamp, version)"
    }
  }
}
```
