The seat lane is attestation only for R; these are not fitted states for every past date.","current_draws":"Today's joint simulations, preserving common draw IDs across all lists and arms. CSV has vote and seat columns per list; JSON stores matrices in party_order. R uses weight_R=1/N; D uses the exported normalized weight_D. Each draw totals 120 seats.","current_poll_weights":"Current R point-filter weights conditional on fitted Q/R, before vector closure. They sum to one per party and reproduce raw_b5_point_pp; they are not pollster ratings or full model derivatives. gain_at_observation=1 for the initializing poll.","current_seat_distributions":"Both arms on the full 0–120 seat axis. raw_draw_count counts shared proposal draws; probability uses each arm's weights. weighted_draw_count is probability times bank size and need not be an integer.

Positive seat_range fields are conditional on representation.","poll_observations":"Numeric source surface prepared for this run, including held and superseded records; not a full discovery database. numeric_input_value can be a deterministic seat zero, as indicated by value_kind.
