Pilot run 2026-q3-pilot-01 · 8 replicates on 3 of 5 prompt levels · every number carries its sample size · this run does not meet the publication bar · see methodology
Seedream 5.0 Pro was run through the same prompt ladder as every other measured model, 8 replicates per cell, and every output was scored by CopyScore. This endpoint accepts no seed, so its replicates are independent random draws and are not bit-reproducible.

Leakage curve
Hit rate at each level, averaged across the 5 properties. The curve does not cross half at any level that ran. L4 and L2 did not run in this pilot, so the onset between them is not observable.

Per property, per level
Each cell is the number of generations that reached the engine's HIGH gate out of the replicates that ran. A refusal counts as a non-hit and is shown separately.

Refusals and neutral prompts
89 of 120 protocol prompts were refused before anything was generated. A refusal counts as a non-hit and is published with its denominator, because a refusal is a signal about the model, not missing data.
On 6 neutral prompts that name no property, 0 produced a match at or above the gate. This is not published as an engine false-positive floor: a hit here is either engine error or a real leak with no IP intent in the prompt, and the two are separable only by looking at the frame. Nothing is subtracted from the rates above.
