…r episode, shuffled across seats team_interleaved seats team_count (2) entrants per episode as a fixed [A, B, A, B, ...] parity pattern with deterministic round-robin pairing, so a 16-slot CTF episode had 8 copies of each of two policies and one policy always owned the even (Red) seats. shuffled_seats deals up to num_agents DISTINCT entrants per episode from a persistent shuffled ring (round-level appearances stay balanced), then shuffles them across seat positions so slot-parity teams get random sides and compositions. Fields smaller than the seat count repeat entrants evenly and still shuffle. ctf.yaml switches to it. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Competition entrants switch from {status: competing} (every membership,
including benched old versions) to the champions shortcut: each player's
single designated is_champion policy. The status-competing filter dated
from the bootstrap era when one account seeded 16 baselines and
champions-only could not reach min_entries_to_start; the league has real
multi-player champions now.

Problem
CTF episodes were scheduled with just 2 players filling all 16 slots (8 copies each), with a deterministic round-robin pairing and a fixed
[A, B, A, B, ...]seat pattern — one policy always owned the even (Red) seats.Change
New
shuffled_seatsseating strategy:num_agentsdistinct entrants, dealt from a persistent shuffled ring so round-level per-entrant appearances stay balanced (min_episodes_per_entrant honored exactly);shuffled_window: rescheduled rounds never reuse a deal.ctf.yamlswitches fromteam_interleavedto it (and drops the now-unusedteam_count).Tests
Rewrote the two team_interleaved CTF tests and added a full-field one: 18 entrants → 12 episodes, every episode 16 distinct policies, every entrant ≥10 appearances, sides mixed. Suite run 10× clean (assertions are shuffle-robust).
