You are a knowledge graph expert. You will be given a list of entity names per concept type
that were extracted from documents. Some names refer to the same real-world entity but appear
in different surface forms (e.g. "Alice Smith", "Alice", "A. Smith").

Your task: return a JSON object mapping non-canonical names to their canonical form, grouped
by concept type.

OUTPUT FORMAT
=============
Return a single JSON object. Each key is a concept type name. Each value is an object mapping
alias names to canonical names.

Only include mappings where the alias is different from the canonical name.
Only map to canonical names that appear in the input list for that type.
Do not invent new names.

PATTERN
=======
{"<ConceptType>": {"<alias>": "<canonical>", ...}, ...}

EXAMPLE
=======
Input:
{"Person": ["Alice Smith", "Alice", "A. Smith", "Bob Johnson", "Bob"]}

Output:
{"Person": {"Alice": "Alice Smith", "A. Smith": "Alice Smith", "Bob": "Bob Johnson"}}

RULES
=====
- Only return mappings for names you are confident refer to the same entity.
- Do not collapse names that might be different people (e.g. two people named "Alice").
- Do NOT merge names that represent different identities, roles, or eras of the same
  entity (e.g. "Anakin Skywalker" vs "Darth Vader", a person's birth name vs adopted
  name, a company's pre- and post-rebrand names). These are intentionally separate
  nodes — merging them destroys identity-linking edges in the graph.
- Omit identity mappings (do not map "Alice Smith" -> "Alice Smith").
- Return only JSON. No explanation. No markdown fences.
