Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
When the JSON input is truncated in the middle of a structural element (e.g., an object or array that is opened but never closed, such as '{"a":[1,2'), Get shall return a parse-related error and shall not panic.
the parser shall always satisfy !input_is_truncated_mid_structure | returns_error_for_truncated_mid_structure

Rationale & tags
Why this requirement exists, and how it is categorised.
Truncated mid-structure input exercises blockEnd returning -1, which is behaviorally distinct from truncated-at-value-boundary where tokenEnd returns len(data).
Verification & provenance
How this requirement was checked: the review trail, edit history, and the machine-analysis status terms (each ⓘ explains what it means).

Variables
| Name | Type | Direction | Description |
|---|---|---|---|
| input_is_truncated_mid_structure | — | True when the JSON input is truncated in the middle of a structural element where an object or array is opened but never closed. | |
| returns_error_for_truncated_mid_structure | — | True when Get returns a parse-related error for input truncated mid-structure, without panicking. |
