Struct MeshManifestEntry 

pub struct MeshManifestEntry {
    pub express_id: u32,
    pub geometry_class: u8,
    pub vertex_count: usize,
    pub triangle_count: usize,
    pub positions_hash: String,
    pub normals_hash: String,
    pub indices_origin_hash: String,
}

Per-mesh manifest entry: enough to identify WHICH mesh diverged and how big it was, without committing the raw vertex data.

Fields

express_id: u32

geometry_class: u8

vertex_count: usize

triangle_count: usize

positions_hash: String

FNV-1a over the position f32 bits (little-endian). Split out from the normals so the cross-target guard can assert it byte-identical for EVERY mesh, including the curved-profile one: the circle-tessellation libm sin/cos gap lands in the near-zero radial-normal components, not here.

normals_hash: String

FNV-1a over the normal f32 bits. The ONLY per-mesh surface allowed to differ across targets, and only for the curved-profile mesh (see the wasm leg’s trig-gap guard).

indices_origin_hash: String

FNV-1a over (express_id, geometry_class, indices u32, origin f64 bits) - identity, topology and placement, byte-identical across all targets.
