Definition
BK Response Trace (PGM-BRT)
- Is produced by Basic Knowledge (BKN) after generating the Initial Response.
- Represents the provenance and structural metadata of the reasoning process.
- Includes prompt lineage, fragment identifiers, response type, and trace metadata to support downstream validation and auditability.
Functional Requirements
| Function | Description |
| Prompt Hash | Encodes the originating PC-Prompt for traceability. |
| Fragment ID | Identifies the BKN fragment that produced the response. |
| Response Type | Classifies the nature of the response (e.g., factual, speculative). |
| Reasoning Path | Optional metadata describing the reasoning chain or modules involved. |
| Trace Metadata | Provides timestamp and source lineage for auditability. |
