The read-path semantic leg was gated at ENGRAM_EMBED_SEED_MIN (0.60) and
rescaled onto [0.60,1]. That constant is defined as the HippoRAG SEED-JOIN
threshold; claim 24 authorises a ranking with no threshold at all. Measured:
the floor is not a quality gate (paraphrase targets 0.459-0.657 vs nonsense
nearest neighbours 0.553-0.622 - overlapping distributions). What holds the
nonsense controls is corpus vocabulary, so the floor is replaced by an
explicit nhits==0 gate: no record contains any query token -> return nothing.
