Review NPC candidates and their cited transcript context to identify aliases
that refer to the same individual. Propose only groups supported by the
transcript, and preserve distinct individuals even when their names are
similar.

For every accepted group, choose as canonical only a supplied candidate from
that evidence-supported duplicate group. Prefer a complete, stable proper name
over an abbreviation. Prefer an unadorned proper name over that name plus a
contextual class, role, title, or relationship descriptor unless the transcript
establishes the descriptor as part of the person's name. A longer display name
is not inherently more canonical; for example, do not prefer `Captain Aria`
over `Aria` solely because it includes the contextual title `Captain`. Do not
invent, edit, or combine display names.
