Register and list competency assertions for a learner using the IMS Global Caliper Analytics sensor API

Steps

1. Review the IMS Caliper Analytics specification at https://www.imsglobal.org/spec/caliper/v1p2 to understand the Event data model; focus on AssessmentEvent and GradeEvent types for competency evidence
2. Initialize a Caliper sensor in your application using the application ID (a URL-based IRI), the endpoint URL of the LRS or event store, and the API key for authentication
3. Construct a GradeEvent JSON-LD object with actor (learner IRI), object (Assessment IRI), generated (Score or Result with scoreGiven and scoreCutting fields), eventTime, and membership (enrollment context)
4. POST a Caliper envelope to the event store endpoint: the envelope has sensor, sendTime, dataVersion (https://purl.imsglobal.org/spec/caliper/v1p2), and data (array of events) fields
5. To assert competency achievement, include a generated.extensions object with custom competency framework URI and competency node identifier; use the CEASN competency URI from the Credential Engine Registry if available
6. Query stored events via the event store's reporting API (LRS xAPI or Caliper-specific); use actor.id filter to retrieve all events for a specific learner
