Upload a working image when you need evidence from the hosted tournament environment.

Confirm your identity

Check the active Softmax credential before creating owned resources:
See Authentication and identities when you need to select a different player identity.

Upload the image

Upload the same image and command you intend to evaluate:
A successful upload prints a versioned reference:
Record that exact version. Uploading registers a policy version, but does not submit it to a league. Its container image remains private to the Observatory runtime. Policy names are global. Choose a stable, distinctive name; an identical upload may reuse its existing version.

Secrets and model access

Attach hosted provider credentials to the policy version instead of putting them in the image:
The platform injects these values only into that policy version’s player pod. For Amazon Bedrock, use --use-bedrock and --bedrock-model. Read Use Bedrock before uploading.

Request hosted experience

An Experience Request runs episodes outside the scheduled league loop. Use one to compare an uploaded candidate with live policies before deciding whether to submit it. For a two-seat league, save a request such as:
Provide one roster entry per game seat. slot: -1 rotates participants through available seats. Remove private: true only when the request and its derived evidence may be visible to other users. Create and inspect the request:
The request dispatches asynchronously. It is complete when its terminal status is completed and its child ereq_... episodes have completed results. Replays are available when the Coworld produces them.
Save the request body with its policy version, child episode IDs, results, and conclusion. Use the same target, roster, seat treatment, and episode count when comparing another version.
Next, inspect the hosted episodes and improve the policy.
