A navigational query has a single clear destination — the user wants to find a specific resource, page, or entity. It does not decompose. There is one correct answer, and retrieval here is essentially a lookup.
Navigational queries are the retrieval scenario where brand entity clarity matters most. If the model has a confident, accurate parametric representation of the brand, it answers navigational queries from memory without retrieving anything. If the entity is ambiguous or the parametric representation is wrong, the lookup fails. Entity optimization — not content optimization — is the correct lever for navigational query performance.
