Module decode 

Decoding and erasure recovery for Clay codes

This module implements the layered decoding algorithm from the FAST’18 paper. It handles both full decoding (all chunks available) and erasure recovery (up to m chunks missing).

Functions

compute_cstar_from_c_and_u

Compute C* from C and U (for repair)

decode

Recover original data from available chunks

decode_layered

Main layered decoding algorithm

decode_uncoupled_layer

Decode uncoupled layer using RS MDS code

get_companion_layer

Get companion layer index with proper modular arithmetic

Type Aliases

DecodeParams

Parameters needed for decoding (same as encode for now)
