Draw one pooled path per real method instead of treating read seeds as distinct
interventions. Random directions remain separate controls. Doses below the
absolute pmass 0.90 gate are hollow and faint rather than silently removed;
only valid doses enter the result table and confidence intervals.

The absolute WVS coordinate carries +-0.07 of item-set variance on a 12-item
battery, so the steer is now reported as a paired difference on the same items.
Per-dose psamples are saved, so every interval is post-processing.
The manipulation check exists because a flat map cannot be read on its own: a
vector that does nothing and a vector that culture does not respond to look the
same. Qwen3-0.6B: per-item changes are large (sd 0.18-0.38) but their signs are
coin flips (7/12 up), and random behaves the same.
