Namespace Tracon · Assembly Tracon.Abstractions.dll
A piece of reference text attached to a single run, kept apart from the
model's instructions.
```csharp
public sealed record AgentRunDocument : IEquatable
```
- Inheritance
- object ← AgentRunDocument
- Implements
- IEquatable<AgentRunDocument>
- Inherited Members
- object.GetType(), object.ToString(), object.Equals(object?), object.Equals(object?, object?), object.ReferenceEquals(object?, object?), object.GetHashCode()
## Remarks
**This is a convention and an audit trail, not a security
guarantee.** No provider gives a hard guarantee that text wrapped
this way is never treated as an instruction; a capable-enough model can
still be steered by content inside a document. The value is in keeping the
data channel visibly separate in the transcript and the run record, and in
the boundary marker surviving content that tries to imitate it.
A document is carried as its own `ChatMessage`, wrapped in a
delimiter, and marked through `AIContent.AdditionalProperties` so the
recording path can tell it apart from the instructions text. The run
record keeps only the document's name and size — never its content.
