2026-10-18. The diversified battery the maintainer asked for (relayed by codex-cloud-2, 49e975f3da) on the owner draft at 6de902eb1d and the envelope's sections 2.0 to 2.4. Families: purpose, layer boundaries, removal, substitution, minimal construction, ambiguity, recovery and scope restraint, in prose, nested JSON, incomplete examples and ordinary communication; four open-ended prompts asked first, before any finding was shown, and never scored by agreement.

Two questions failed in all five runs, because of the text: what "still fails by name" means for a writer outside OCX, and what a dying owner loses. The open prompts found, among others: the draft drops the turn between OCX's commands although tools still write the server's repository; a dying owner loses what it had read from its inbox; section 2.3's publication text contradicts the draft; section 2.1's recognition rule reads two ways; the draft does not say why a lock rather than the record's own "first that counts" settles who acts.

The attachment battery-owner.tar, plain, holds the questions and expected answers (hashed before the first request), every request and reply, the scoring, the open findings, and the wording changes proposed.
