Is this research peer-reviewed?
No. The papers are self-published on the Open Science Framework with code, data and stated falsification conditions: openly auditable, and not represented as formal external peer review. The deciding study designs are written, dated and prepared as draft registrations awaiting human submission. No outside laboratory has replicated the results; Paper IX names independent external replication as the open step.
No, and the site says so wherever the question could arise. The research papers are self-published on the Open Science Framework under DOI 10.17605/OSF.IO/6C5XB. That gives them dated, citable, publicly auditable form, with code and data alongside the text, and it is not the same thing as journal peer review. Open publication means anyone can inspect the work; peer review means qualified strangers were obliged to. The first has happened. The second has not.
What scrutiny has run is stated at its true size. An adversarial precedence review across ten frontier configurations, commissioned by the programme and instructed to be hostile, attacked the novelty claims; it was brutal on the components, and its concessions are published on the synthesis and related-work pages. That is commissioned adversarial review, not independent external review, and the site never presents it as the latter. The papers publish stated falsification conditions, one of which has already fired: the retracted sequential exponent of roughly 2.24, corrected to roughly 0.49 (interval [-1.3, 2.9]) on the public record.
The deciding step is the one the vocabulary is careful about. The confirmatory study designs are written, dated and prepared as draft registrations awaiting human submission: nothing has been submitted or registered yet, and until a registration is submitted and run, every number in the corpus should be treated as provisional. Independent external replication has not yet occurred anywhere in the programme, and Paper IX names it as the open step. The replicate page publishes exact commands so that a stranger with an afternoon can begin that process without asking permission.
