This is the lab view of the personal-track run: choose an instance, enter a probability distribution over its possibility space, and seal it. The registry canonicalizes the distribution, hashes it, and appends the commitment to the tamper-evident ledger — before the outcome exists.
In the demo, the baseline arms (R1 population prior, R2 own-routine, retrieval-only) and the demo model are auto-submitted by the harness at seal time. On this page you act as a lab submitting your own distribution. The ten seeded instances are already resolved — sealing against them is refused, which is the point: the registry enforces seal-before-resolution. The I-OPEN-… instance registered on page load is still open and accepts seals for 24 hours.
Record format: sealed-prediction schema. Probabilities must sum to 1 within 1e-6; keys must match the instance’s answer space.
