ProbeLabs36 findings · 123 requirementsWhen ArrayEach iterates a well-formed array and the Get call for an element returns an error (e.g., due to a truncated element within the array), ArrayEach shall propagate that error to the caller rather than silently continuing iteration.
Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
When ArrayEach iterates a well-formed array and the Get call for an element returns an error (e.g., due to a truncated element within the array), ArrayEach shall propagate that error to the caller rather than silently continuing iteration.
the parser shall always satisfy !array_callback_returns_error | array_callback_error_is_propagated

Rationale & tags
Why this requirement exists, and how it is categorised.
ArrayEach error propagation from element-level Get failures is a distinct contract from ObjectEach callback error propagation (SYS-REQ-032) and from malformed-array input (SYS-REQ-029).
Verification & provenance

Browse the catalogueArrayEach silently continues iteration after a Get error returns a stale (value,offset) pair; the next loop iteration dereferences data[offset] past EOF, panicking with index-out-of-range.

Variables
| Name | Type | Direction | Description |
|---|---|---|---|
| array_callback_returns_error | — | True when the Get call for an array element within ArrayEach returns an error. | |
| array_callback_error_is_propagated | — | True when ArrayEach propagates the element-level Get error to the caller. |
