29. runtime/forward

Part: IV · Runtime
Package: github.com/openfluke/welvet/runtime/forward
Status: ok — ✅

When

Walking a Grid/Stack with the shared runtime/forward path.

Where

import "github.com/openfluke/welvet/runtime/forward"

cd 29-forward && source ../env.sh && go run .

Why

A grid of heterogeneous ops needs one walker that dispatches by concrete type and fails loudly on unknowns.

What

Forward[T](grid, input) → Result tape; Cell[T] for single-cell dispatch. Covers Dense…Residual + extended wired ops.

Sample output (captured)

true <nil>

Live capture from go run ./cmd/runall on local ../../welvet (exit 0).
