ProbeLabsviewing a historical runWhen Delete is called with an array-element path on input where the array is truncated (e.g., Delete([]byte(`{"a":[1,2`), "a", "[1]")), the parser shall return the original byte payload unchanged 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 Delete is called with an array-element path on input where the array is truncated (e.g., Delete([]byte({"a":[1,2), "a", "[1]")), the parser shall return the original byte payload unchanged and shall not panic.
the parser shall always satisfy !delete_array_input_is_truncated | (delete_returns_original_input_on_truncated_array & delete_completes_without_panic_on_truncated_array)

Rationale & tags
Why this requirement exists, and how it is categorised.
Array deletion on truncated input exercises the same tokenEnd sentinel pattern as object deletion but through a different code path in Delete (the array branch).
Verification & provenance

For an array-element path (last key
[N]) the array branch calls internalGetConfig with the full key list and returns the original input on error (parser.go:1320-1323); a truncated array such as{"a":[1,2yields MalformedArrayError from blockEnd, so the untouched payload is returned. Even when a truncated element resolves at end-of-input, the trailing-comma cleanup guards withendOffset+tokEnd >= len(data)before any deref (parser.go:1328), again returning data unchanged. No unchecked index is taken, so no panic. MCDC Row5 truncated-array witness passes.Cited code (3)
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.

MC/DC truth table· 5 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.
