Asset, maintenance and calibration
Tracked asset instance, ownership, operation, maintenance, inspections and calibration. A configuration item is linked to the asset but is not identical to it.
Queued for research
Claude: not-started; Grok: not-started.

Subject boundary and candidate types
- AssetInstance
- Custody
- MaintenancePlan
- MaintenanceEvent
- CalibrationEvent
Deep research questions
- How to distinguish the owner, the custodian and the operator?
- How does an asset survive component replacement?
- When does a calibration stop confirming fitness?
Verifiable invariants
- A serial belongs to the manufacturer's scheme
- A repair does not change identity without a rule
- A calibration certificate has a range and a term
End-to-end acceptance scenario
A leased instrument, a unit replacement and an expired calibration preserve the chain of responsibility and fitness.
Negative case
A successful calibration of one instrument extends to all instruments of the model.
Approaches to compare
- APQC/BPMN: process definitions and execution
- GS1 EPCIS/SCOR: traceability and supply chain
- IDTA AAS and PLM/EAM/WMS practice: product, instance and maintenance

Result requirements
Every card is executed together with the full research contract: definitions, fields and cardinalities, lifecycle, sources, data mastership, rights, the five object facets, at least eight invariants, positive and negative examples, dependencies, migration and applicability limits.
