# laion/codeforces-v2 was deleted from HF; the versioned replacement lives in
# open-thoughts/TaskTrove at laion__codeforces-v3/tasks.parquet (repo sha 71217c0f4a2f,
# tasks declare [environment] storage_mb = 4096 so Daytona sandboxes stop hitting ENOSPC).
# resolve_rl_train_data does not understand org/repo::subdir selectors (escalated
# 2026-08-30), so the subdir is pre-extracted on Jupiter and passed as a local path,
# which the launcher forwards verbatim. Extracted on a COMPUTE node to /e/data1, not
# $SCRATCH/tasks: login-node small-file creates serialize at ~1.3 s/file (cxiWaitEventWait).
