Rare-category (F) retention across resampling rounds -- text description (accessible route)

Three conditions, three fixed seeds each, 200 draws per round,
5 recursive rounds after the shared round-0 draw. "Retained"
means the rare category's count in that round's sample is greater than zero.

original-data baseline: round 0: retained in 3/3 seeds; round 1: retained in 3/3 seeds; round 2: retained in 3/3 seeds; round 3: retained in 3/3 seeds; round 4: retained in 3/3 seeds; round 5: retained in 3/3 seeds.

fully recursive (replace): round 0: retained in 3/3 seeds; round 1: retained in 3/3 seeds; round 2: retained in 3/3 seeds; round 3: retained in 2/3 seeds; round 4: retained in 2/3 seeds; round 5: retained in 2/3 seeds.

recursive with retained original data: round 0: retained in 3/3 seeds; round 1: retained in 3/3 seeds; round 2: retained in 3/3 seeds; round 3: retained in 3/3 seeds; round 4: retained in 3/3 seeds; round 5: retained in 3/3 seeds.

Once a run's estimated distribution assigns the rare category zero
probability, that run can never draw it again -- a genuine absorbing state
in this model, not a smoothed trend line. Full per-round counts for every
category are in counts.csv; the rare category alone is in
rare-category-retention.csv.
