Round 19: response to reviewers
Protocol version reviewed: 0.19.0. Outcome: accepted.
Verdicts: GPT-6 Astra ACCEPT; Fable 5.1 ACCEPT; Grok 4.7 ACCEPT. All three reviewers returned ACCEPT on the same version, which ends the protocol peer review (rounds 1 to 19, 2026-10-12 to 2026-10-13). Version 0.19.0 is the version that will be registered once the administrative checklist is complete; no text was changed after acceptance.
GPT-6 Astra and Grok 4.7 raised no comments. The three items of Fable 5.1 are answered below and recorded in ../comments.csv. The two editorial items are deferred to the pre-analysis amendment so that the accepted text stays the reviewed text.
Fable 5.1 (fable-5.1)
F19-1 (minor; Response record). The G18-2 response listed six deferred rows; F18-3, deferred in the same round, makes seven.
Response (corrected). Agreed; the set covered by the pointer at version 0.19.0 is F12-note, F14-note, F15-note, F16-note, F17-4, F17-5 and F18-3. The protocol rule needed no change.
F19-2 (minor; Absolute effects). Scope of "and f_a reaches the analyzed horizon" after the sensitivity parenthetical.
Response (deferred to amendment). The reading that the condition governs f_a in both analyses is the intended one, and the text forbids extrapolation in any case. Version 0.19.0 is the version all three reviewers accepted, so the wording "in either analysis" is deferred to the pre-analysis amendment rather than made now.
F19-3 (note; Sensitivity analyses). The reference arm 95 percent analysis is defined inline but not listed in the Sensitivity analyses section.
Response (deferred to amendment). Deferred to the pre-analysis amendment for the same reason as F19-2; the inline definition is executable.
Matters deferred to the pre-analysis amendment
Every row of ../comments.csv whose action contains deferred to amendment: F12-note, F14-note, F15-note, F16-note, F17-4, F17-5, F18-3, F19-2 and F19-3. They must be settled by a logged amendment before the first analysis of an affected outcome.
