func MergeUnified ¶

func MergeUnified(dst, src *spec.UnifiedFile, srcDir string)

MergeUnified merges src into dst such that dst's existing values WIN on conflict at the same leaf (root-wins). This means when MaterializeLoadedProject replays the walk's documents in order (the root file first, then its flat imports), the root file's values are already present before any import's fields are considered, so root wins.

For included files: the same MergeUnified is called but dst already contains the root's values, so those fields stay untouched. src's fields that aren't present in dst get copied over. That's the desired semantics.
