Two defects behind a reported x1.9.
Spans overlap — a phrase and one of its own words match the same tokens
and their biases ADD. Intended, so the word reinforces the phrase, but
unbounded three overlapping x1.5 spans reach an effective x3.4 on one
token. Bounded against the strongest SINGLE span, so an explicit
(word:2.0) still means exactly 2.0.
And it shipped on by default. It changes what the model sees on every
rated run, and it is gated on is_h3_clip — which is why disconnecting
CLIP made generations normal again. Now a toggle, off.
Also replaces prefer_wired_conditioning with clip_owns_prompt: a wired
conditioning owns the prompt by default, and the old order is the opt-in.
