Run 12fb1efb-23d5-4a32-ad87-ed63fb3efcd5

Status: interrupted. Experiment: fac6a2ec-dc86-4f18-affa-bc50338e88d8. Tier: engine arena (paired seeds, deterministic tapes).

Planned: 256. Attempted: 11. Completed: 11. Incomplete: 0. Unplayed: 245.

The runner process was killed by a shell timeout on the controlling session after 11 of 256 games; the tournament log is empty and no summary was written. The 11 completed games are retained in the run folder (slot wins: 0 → 4, 1 → 4, 2 → 1, 3 → 2) but a partial cohort carries no evidential weight and is not pooled into any comparison. The experiment was rerun from scratch; the daily log names the replacement run.

Manifest SHA-256: see runs/12fb1efb-23d5-4a32-ad87-ed63fb3efcd5/manifest.json; the run folder predates inventory writing.

Games were played offline by the engine arena with explicit seeds; every seed was played once per lineup rotation. Seats received only their own redacted observation and participant events. This tier supports development and diagnosis; it is not a protocol-arena confirmation.
