ProbeLabsviewing a historical runWhen ObjectEach encounters an object entry that is truncated (e.g., '{"a":1, "b":' where the second value is incomplete), the parser shall return a parse-related error and shall not panic.
Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
When ObjectEach encounters an object entry that is truncated (e.g., '{"a":1, "b":' where the second value is incomplete), the parser shall return a parse-related error and shall not panic.
the parser shall always satisfy !object_is_truncated_mid_entry | returns_error_for_truncated_object_entry

objectEachConfig fails loud on a truncated entry: after skipping the colon, config.Get on the incomplete value (e.g. '{"a":1,"b":') returns a parse error that is returned directly at parser.go:1998-1999, and truncation before the colon/next-token makes nextTokenConfig return -1 -> MalformedJsonError (parser.go:1937/1989). Every data[offset] index is guarded by a preceding nextTokenConfig/-1 check, so a truncated nested object like '{"a":{"b":1' returns an error without panicking. TestObjectEachTruncatedMidEntry confirms no panic across the truncated-value cases.

Obligations
What this requirement must witness to be considered satisfied — the required evidence, and the tests that discharge each one.
The tests that discharge each obligation aren't available for a historical run
The evidence matrix behind each obligation comes from the live audit index, which can't be rebuilt for a past commit. Nothing here means unknown — not that the requirement has no obligations.
Formula evidence
The formal formula behind this requirement, the variables it is written over, and the tests that exercise it (each term is explained inline).

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.
