Identical texts and trivial disputes cost no model call; an alt verdict takes the
alternative's own words, base/unsure keep the base and only unsure is flagged;
insertions and deletions land in the right place; the reading order alternates; the
model gets the base's context. Three consecutive model errors stop the whole
reconciliation (base text, none of the partial changes, reason recorded) while a
success in between resets the breaker; a cancelled job is an error, not 'skipped'.
Spots carry the second they start at; the stored list is capped, the counts are not.
Red: Reconcile, Options, MaxContested and domain.Reconcile* are undefined.
