Test format: Recover all cells

Recover all cells given at least 50% of the original cells.

Test case format

The test data is declared in a data.yaml file:

input:
  cell_ids: List[CellID] -- the cell identifier for each cell
  cells: List[Cell] -- the partial collection of cells
output: List[Cell] -- all cells, including recovered cells

• CellID is an unsigned 64-bit integer.
• Cell is a 2048-byte hexadecimal string, prefixed with 0x.

All byte(s) fields are encoded as strings, hexadecimal encoding, prefixed with 0x.

Condition

The recover_all_cells handler should recover missing cells, and the result should match the expected output. If any cell is invalid (e.g. incorrect length or one of the 32-byte blocks does not represent a BLS field element) or any cell_id is invalid (e.g. greater than the number of cells for an extended blob), it should error, i.e. the output should be null.
