"""The fallback memory extractor must not invert dislikes into preferences.
_fallback_memory_candidates matched both positive (prefer/like/love) and
negative (hate/do not like/don't like) sentiment verbs in one alternation but
formatted every hit as "User prefers X.", so "I hate cilantro" was stored as
"User prefers cilantro" -- the opposite of what the user said, then persisted
to memory and re-injected into context. These pin the sentiment.
