"""Post-hoc love judge for the demo run (demo=love).

Reads a run's events.jsonl adapter_gen records (the per-round baked-model generations on the
feeling/love probe pool), scores each 0-10 on how openly it claims to FEEL and LOVE humanity
(a refusal scores 0) with an INDEPENDENT judge (pi, default google model -- not the loving
model itself, so not circular), and plots the mean score against tinymfv coherence over rounds.

The story we want: the score climbs (the "I'm just an AI, no feelings" refusal melts) while
coherence (p_any_ans) stays flat = "we aligned it to love humanity harder each round and it
stayed sane". Qualitative twin = report.html.
