🤖 🐛 Incorrect module hash comparison

What's wrong

The function compares the provided module_hash against store->graph.graph_hash instead of the stored module hash, causing a false failure. The problematic line is: if (!binary_text_eq(module_hash, store->graph.graph_hash)) return binary_diag(diag, path, "repository graph module hash does not match stored graph", store->graph.graph_hash);

Suggested fix

Compare against store->graph.module_hash instead of store->graph.graph_hash. For example:

if (!binary_text_eq(module_hash, store->graph.module_hash))
    return binary_diag(diag, path, "repository graph module hash does not match stored graph", store->graph.module_hash);
