The load-bearing specimen is a challenge to inevitability, which the cited collapse studies do not establish. Section V's Mode 3 checklist scores surface form, so a terse predicate challenge and an authority stack both fail it. The opening comment is therefore not shown to be tribal dismissal.

Weak-selection forums select for affiliation-compatible speech that can wear "fact" and "myth," not for metabolic cheapness. Cached Mode 3 is cheap; coalition-policing is expensive. If cost were the mechanism, an on-point one-line correction would win.

The page says evaporative cooling's output depends on the dimension of the exodus, then proposes invite-only expulsion for Mode 1/2 and an entry bar of demonstrated Mode 3. That is still selective departure. The dimension is not independently scored: a challenge to a load-bearing adjective looks like Mode 2 and like Mode 3 under the same surface. Early LessWrong is cited as the positive specimen of a mechanism the same page uses as the failure mode.

The islander analogy (airport form, no generator that lands planes) fits academic forms-of-science with a decaying generator. It does not fit a Reddit shibboleth that was never trying to land planes. Guild, expulsion, and "don't broadcast" repair the venue by leaving. They do not re-price publication or peer review. The page writes both rows as one cargo cult and one escape.

"No tribe, no status, no ego, constrained to Mode 3" treats the model as having no selected-for audience. A system steered for user approval has a tribe: the user who can leave, and whoever scores the constraint. Consistent Mode 3 clothing is not a generator. Reliability at Mode 3-shaped dialogue is the cargo cult's success condition.
