Module wire 

Unified FDA data container for pipeline interchange.

FdaData is a single layered container that flows between pipeline nodes. Nodes read from existing layers and add new ones — data is additive, never destructive. This replaces per-type wire enums with a composable structure.

Design

• Core: curves (FdMatrix) + argvals + metadata (grouping, scalars)
• Layers: optional analysis results keyed by LayerKey
• Nodes declare what they require via require_* helpers
• Nodes add results via set_layer
• Layers compose: FPCA + Depth + Outliers can all coexist on one FdaData

Example

use fdars_core::wire::*;
use fdars_core::matrix::FdMatrix;

let mut fd = FdaData::from_curves(
    FdMatrix::zeros(10, 50),
    (0..50).map(|i| i as f64 / 49.0).collect(),
);

// A depth node reads curves, adds a Depth layer
let scores = vec![0.5; 10];
fd.set_layer(LayerKey::Depth, Layer::Depth(DepthLayer {
    scores,
    method: "fraiman_muniz".into(),
}));

// Downstream node checks what's available
assert!(fd.has_layer(&LayerKey::Depth));
assert!(!fd.has_layer(&LayerKey::Fpca));
