Publishes all 21,440 recorded Coder pass@4 conversations from 5,360 evaluated tasks. Keeps 704 tasks solved at least once, preserves 4,656 unsuccessful tasks and 95 prior exclusions in archive, and records 565 pending tasks separately. Includes frozen provenance, settings and output-cap caveat, reproducible selection, and measured trajectory statistics. Task payloads are unchanged. This partial teacher release does not claim complete current-profile validation.
