what happens when multiple people edit the same text
simultaneously?

>reconcile(parent: str, left: str, right: str) ->

solves a fundamental challenge in collaborative editing: what happens when
multiple people edit the same text simultaneously?
<code>reconcile(parent: str, left: str, right: str) -> str</code>
takes conflicting concurrent edits and intelligently merges them into a unified
result. Beyond basic conflict resolution, it offers sophisticated merging
heuristics, flexible tokenization options, and cursor position tracking.
</p>
<p>
The algorithm begins with your chosen tokenizer, then
applies Myers' diff algorithm to compare the original text
with both conflicting versions. These diffs undergo
transformation to preserve meaningful change sequences,
before a final merge strategy—inspired by Operational
Transformation (OT)—reconciles all conflicting modifications
without losing any edits.
