Struct FragmentMeta 

pub struct FragmentMeta {
    pub fragment_id: String,
    pub chunk_id: String,
    pub k: usize,
    pub size_bytes: u64,
}

Lightweight record of a single fragment stored on disk.

Does not hold the fragment data — only enough information for the quality monitor to issue proof-of-storage challenges and for the storage manager to locate the file.

Fields

fragment_id: String

UUID of the fragment (also the filename without extension).

chunk_id: String

BLAKE3 chunk hash prefix this fragment belongs to.

k: usize

Number of source symbols k for this fragment’s chunk.

size_bytes: u64

On-disk size in bytes (full binary blob including header).
