Struct FormProfileSnapshot 

pub struct FormProfileSnapshot {
    pub width_bytes: u64,
    pub width_samples: u64,
    pub reads: u64,
    pub writes: u64,
}

Observed width and access profile for one edge table.

Per-table aggregate only: total property-byte width over sampled writes, sampled write count, and relaxed read/write access counters. Memory is O(1) per table plus the existing per-group write map; no per-edge state is kept and over-limit groups aggregate by owner id. Missing snapshots from old checkpoints decode as unknown, never as zero, so decision logic must treat unknown as keep-columnar.

Fields

width_bytes: u64

width_samples: u64

reads: u64

writes: u64
