Every Arena run behind https://microduckstudio.com/train/arena/

Raced on 2026-10-27 with the Arena's own scorer, microduck-arena 0.6.0, the wheel Pollen's
microduck-challenges installs at commit 4b675ebf4d7c7b961cd78da94bfc37ca1686d321:
  https://github.com/pollen-robotics/microduck-arena/releases/download/v0.6.0/microduck_arena-0.6.0-py3-none-any.whl
on an x86_64 Linux machine, the same architecture as the Arena's Space, one run at a time per policy:
  arena score <policy.onnx> --event <event>
A time from a machine other than the Arena's is indicative, as the Arena's README says; the board's
time is the Arena's own run. The entries we made are at the end, with the Arena's own answers, and
after them what the board said about the runs the page compares with ours.

The policies (name, what it is, where the file is, its sha256):

Our second entry: b003f, on sprint-2m and then on hill-climb-1m5, published from craigm26's Hugging
Face account with the same publish tool, 2026-10-27. One repo, published twice: the second publish
changed only the manifest's event, so each entry's revision names the event it raced:

What the board said, read from the Arena's API on 2026-10-27 (GET /api/runs/<run id>, and its
/settle and /trace, which the API serves as 21 little-endian float32 values a frame, 50 frames a
second; as we read them, the duck's position, then the trunk's orientation as a quaternion, then
its 14 joints. Tilt below is the trunk's angle from upright, worked out from that quaternion):

Pollen's sprint reference on sprint-2m, entered as "Pollen Sprint Reference", run 01M3PVB3EC1HG6N3SYZZZS,
the same policy.onnx as ours by sha256 (adbc1594..., at revision 3e59e802dea470f62c16a018ee2a3b603374ae92):
  board: 4.886 s (5/5 seeds) at 0.55 m/s, per seed 4.890 4.875 4.875 4.930 4.860, the same as ours above, start for start
  trace: the settle moves it from x = 0.00 m to 0.05 m; the trunk stays within 3 degrees of upright

Our first entry, b003b on hill-climb-1m5, run 01M5Z66V0M99E7BA87B42H:

  trace: the settle moves it from x = -0.02 m to 0.04 m; the trunk stays within 10 degrees of upright

Our second entry, b003f on sprint-2m, run 01M5ZCR92S48BMSVV3MW8P:
  board: 5.108 s (5/5 seeds) at 1.15 m/s, per seed 4.905 5.070 6.705 4.035 4.825, the same as ours above, start for start

The sprint's best run when we looked, greecree's sprint-2m-sprint-leader-v2, run 01M5YY1WYCDYN4FRB7BF4N:
  board: 0.839 s (5/5 seeds) at 1.15 m/s, rank 1
  trace: the untimed settle moves it from x = 0.00 m to 0.30 m, and it is moving at 1.75 m/s when the
  clock starts; timed, it covers x = 0.33 m to 2.30 m in 42 frames, its trunk 7 to 52 degrees from
  upright before its last 6 frames, past 60 degrees only in the last 4, and 106 degrees at the end

The hill's best run when we looked, jrubiosainz's game-hillclimber-remix8, run 01M5V33SPVY6R6NBBB4NZW:
  board: 0.744 s (5/5 seeds) at 0.30 m/s, rank 1
  trace: the untimed settle moves it from x = -0.02 m to 0.21 m, and it is moving at 1.48 m/s when the
  clock starts; timed, 37 frames, its trunk past 60 degrees only in the last 2, and 93 degrees at the end
