Enum MergeFallbackReason 

pub enum MergeFallbackReason {
    MissingRoot,
    ShapeMismatch,
    NodeLengthMismatch,
    ChildFallback,
    DeleteResolution,
    DiffBatch,
}

Why merge left a fast path and continued through a broader path.

Variants

MissingRoot

At least one side had an empty root, so structural node comparison could not run.

ShapeMismatch

Structural nodes did not have compatible shape, level, or key layout.

NodeLengthMismatch

Same-layout internal nodes had different child counts.

ChildFallback

A child subtree could not be structurally merged.

DeleteResolution

A structural conflict resolved to delete, which requires the batch path to keep rebalancing correct.

DiffBatch

Merge continued through the diff/batch path.
