ProbeLabsviewing a historical runWhen ParseString receives a malformed encoded string literal, the parser shall return the documented malformed-value error.
Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
When ParseString receives a malformed encoded string literal, the parser shall return the documented malformed-value error.
the parser shall always satisfy raw_string_literal_is_well_formed | returns_parsestring_error

Rationale & tags
Why this requirement exists, and how it is categorised.
Malformed-string failure is externally visible and should be specified independently from valid ParseString decoding behavior.
Verification & provenance
How this requirement was checked: the review trail, edit history, and the machine-analysis status terms (each ⓘ explains what it means).

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.

Variables
| Name | Type | Direction | Description |
|---|---|---|---|
| raw_string_literal_is_well_formed | — | True when ParseString receives a well-formed raw JSON string literal body. | |
| returns_parsestring_error | — | True when ParseString returns the documented malformed-value error for a malformed encoded string literal. |

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.
