ProbeLabs23 findings · 123 requirementsThe fastest JSON parser for Go — formally verified with ReqProof (real library, master).
When ObjectEach addresses a well-formed non-empty JSON object, the parser shall invoke the callback with the correct key, value, and value type tuple for each addressed object entry.
Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
When ObjectEach addresses a well-formed non-empty JSON object, the parser shall invoke the callback with the correct key, value, and value type tuple for each addressed object entry.
the parser shall always satisfy !addressed_object_is_well_formed | addressed_object_is_empty | object_callback_receives_entries

Rationale & tags
Why this requirement exists, and how it is categorised.
Correct object entry reporting is a distinct externally visible contract from empty-object handling, malformed-input failure, and callback error propagation.

Obligations
What this requirement must witness to be considered satisfied — the required evidence, and the tests that discharge each one.
No obligations recorded for this requirement
Proof obligations are recorded once evidence is generated. None have been captured here yet — this is expected, not a gap in the requirement itself. A required class of evidence the requirement must witness — the bridge between the requirement existing and it being proven.

Variables
| Name | Type | Direction | Description |
|---|---|---|---|
| addressed_object_is_well_formed | — | True when ObjectEach is operating on a well-formed addressed JSON object. | |
| addressed_object_is_empty | — | True when ObjectEach is operating on an addressed object that contains no entries. | |
| object_callback_receives_entries | — | True when ObjectEach invokes the callback with the correct key, value, and value-type tuple for each addressed object entry. |

MC/DC truth table· 4 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.
