Struct SectionHeader 

pub struct SectionHeader {
    pub manifest_size: u32,
    pub assets_size: u64,
    pub checksum: u32,
}

Header for data embedded in the __SMOLVM,__smolvm Mach-O section.

This format is used for macOS single-file binaries where assets are stored inside the executable’s Mach-O structure, allowing proper code signing.

Layout (32 bytes total):

Offset  Size  Field
0       8     magic ("SMOLSECT")
8       4     version (u32 LE)
12      4     manifest_size (u32 LE)
16      8     assets_size (u64 LE)
24      4     checksum (u32 LE)
28      4     reserved (zeroes)

Following the header:

• Manifest JSON (manifest_size bytes)
• Compressed assets (assets_size bytes)

Fields

manifest_size: u32

Size of manifest JSON in bytes.

assets_size: u64

Size of compressed assets in bytes.

checksum: u32

CRC32 checksum of manifest + assets.
