Struct Documentation

struct FactorFileFooter

Binary file footer for factor files with metadata.

Format has changed: footer is now at the END of the file instead of the beginning. This allows writing factors directly without knowing metadata in advance.

File structure: [Factors: array of Factor structs (24 bytes each)] [Optional: sequence names (null-terminated strings)] [Optional: sentinel indices (uint64 array)] [Footer: FactorFileFooter struct]
