Event origin
Event origin documents the initial occurrence that is the subject of tracing. The record includes a clear identifier for the initiating event, the originating source or agent, the timestamp or estimated time window, and immediate contextual markers such as location, initiator role, and initial annotations. The focus is descriptive: what occurred, where it was first recorded, and which artefacts or entries preserve the first trace. The purpose of this section is to anchor subsequent attribution by preserving primary properties that are stable and verifiable over time.
Context anchors
Context anchors are the local properties that frame an event. Anchors include surrounding records, cross-references, environmental tags, and any metadata captured at the time of the event. These anchors are recorded as structured descriptors so they can be matched and compared across records without altering the original entry. Context anchors preserve the conditions in which an action was taken and provide multiple points of reference for later comparison or reconstruction.
