study record: H1 (stopped): no verdict

H1 was a preregistered demand test of one landing page. The owner stopped it on day 2 of 21, on 2026-10-21, to reposition the site as datapce readout. The study has no verdict. This record makes no offer.

  1. The rules were hashed and tagged before launch, on 2026-10-17.
  2. The window opened on 2026-10-20 and was set to run 21 days.
  3. The page changed in the window: v0, R1, R2 and R3. Exposure is pooled.
  4. The owner stopped H1 on 2026-10-21, day 2 of 21, to reposition the site.
  5. At the stop, 242 of 500 page loads were counted (15:39Z). Qualified requests: 0, but the private request log was not re-read.
  6. No verdict was given. The planned end, 2026-11-09, was not reached.

Where the rest is

  • The rules, as they stood before launch: prereg-h1.txt.
  • The full page of version R3 is kept in the project repository at commit 673f6ed. It is not served.
  • Persona panels and simulations are SYNTHETIC and never show demand.
  • Back to datapce readout.
