Struct FrameSnapshot 

pub struct FrameSnapshot {
    pub tick: u64,
    pub inputs: u16,
    pub diff_start: u32,
    pub diff_count: u16,
    pub checksum: [u8; 32],
}

Metadata snapshot for a single simulation frame.

Stored in the RollbackBuffer. Points into the DiffPool via diff_start and diff_count — no data duplication.

Fields

tick: u64

Monotonic tick counter.

inputs: u16

10-bit packed InputBits (u16 for alignment).

diff_start: u32

Index into DiffPool where this frame’s diffs begin.

diff_count: u16

Number of 18-byte diffs produced this frame.

checksum: [u8; 32]

Blake3 checksum of physical state after this frame.
