Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
When ObjectEach is called on input truncated mid-structure where the object or a nested structure is not closed, the parser shall return an error without panicking.
the parser shall always satisfy !objecteach_input_is_truncated_mid_structure | returns_error_for_objecteach_truncated_structure

Rationale & tags
Why this requirement exists, and how it is categorised.
ObjectEach iterates entries by calling Get for each value. Truncated mid-structure input can produce sentinel values from blockEnd that affect iteration.
Verification & provenance
How this requirement was checked: the review trail, edit history, and the machine-analysis status terms (each ⓘ explains what it means).

ObjectEach (parser.go:1908) delegates to objectEachConfig, which returns an error on any mid-structure truncation rather than panicking: an unclosed nested value makes config.Get fail and that error is returned (parser.go:1998), and a missing delimiter/closing brace makes nextTokenConfig return -1 -> MalformedArrayError (parser.go:2008). Tracing
{"a":{"b":1-> Get on the nested value hits blockEnd==-1 -> MalformedObjectError;{"a":1,"b":2and{"a":"hellosimilarly resolve to errors with no OOB indexing. TestObjectEachTruncatedMidStructure (recover-guarded) and MCDC rows 2/3 confirm error/no-panic behavior.Cited code (4)

MC/DC truth table· 3 rows
Each row assigns the formula's conditions (T/F) and shows the Result— the formula's value for that input row, not a test pass/fail. A row proves a condition when flipping only that condition flips the outcome. The test that covers each row is linked.
