Prefix/suffix trimmed first; adjacent deletes and inserts read as one Replace;
beyond 3,000 edits (two texts sharing almost nothing) the middle is one Replace
instead of gigabytes of trace. Mutation-checked: a wrong tie-break, missing
replace coalescing, wrong suffix accounting and a punctuation-bearing key each
turn tests red.

A random-input property test compares the equal runs against a dynamic-programming
LCS: a diff that is valid but not minimal would turn real agreement into disputes
the model is then asked about. A 6,500-word, 380-edit case mirrors a real hour.

Keeps the word as written, keys it without case/punctuation/hyphens/plus, joins a
lone dash or full stop to its neighbour so it is not a word the engines can
disagree about. Red: package reconcile does not exist.
