- JSON Required item keys; compound keys use explicit user-defined identifiers
- ["A","B","C"]
- JSON Present valid item keys
- ["A","B","D"]
- Missing required keys
- ["C"]
- Additional keys
- ["D"]

Try another scenario
- JSON Required item keys; compound keys use explicit user-defined identifiers
- ["A","B","C"]
- JSON Present valid item keys
- ["A","B","C"]
- Missing required keys
- []

- Required coverage (%)
- 100
Calculation method
Calculation method
Missing required keys
Sorted required set minus valid-present set.
Additional keys
Sorted valid-present set minus required set.
Required coverage (%)
100 × cardinality(intersection) / cardinality(required); empty requirement set returns 100.
Symbols and units
- a
- JSON Required item keys; compound keys use explicit user-defined identifiers
- b
- JSON Present valid item keys
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Required issued chip IDs versus valid chip IDs after finish-read AND return reconciliation. To distinguish read/return gaps use compound chip/read and chip/return keys. No timing result correction or inferred chip identity. Supported limits: Up to 1000 keys per list. Duplicate keys are rejected. Presence is not a legal, security, scientific, or quality certification.
