Enum MergeOrAlign 

pub enum MergeOrAlign {
    SkipExisting,
    NewLeft,
    NewRight,
    Wide,
}

Per-step branch tag for --add progressive alignment, mirroring C disttbfast.c::mergeoralign[] (lines 4188-4302):

• SkipExisting (‘n’): both subtrees are existing-only — the alignment is already in place; do nothing.
• NewLeft (‘1’): only the LEFT subtree contains a “new” sequence.
• NewRight (‘2’): only the RIGHT subtree contains a “new” sequence.
• Wide (‘w’): both subtrees contain new sequences — full DP merge.
