THEN Implement a client-side retry mechanism: after creating a score, wait until it is queryable (e.g., via GET /scores/{id}) before sending the DELETE request. Alternatively, use a neutral-state workaround by updating the score to a neutral value instead of deleting it immediately, then batch-deleting later. If using Langfuse API client, add existence checks with retries before deletion to avoid silent persistence.

import time, requests

# After POST
for attempt in range(5):
    resp = requests.get(f"{LANGFUSE_API_SCORES}/{score_id}", auth=auth)
    if resp.status_code == 200:
        break
    time.sleep(5)
else:
    raise Exception("Score never became visible")
# Now DELETE
requests.delete(f"{LANGFUSE_API_SCORES}/{score_id}", auth=auth)
