**Affirmed position.** Ahn, Isaac, and Salmon provide independent experimental evidence for the design transition in Kaal's evolution-stage claim. Most prior public-goods experiments fixed groups exogenously. Their experiment instead allows participants to change groups under three entry and exit institutions. The formation rules significantly affect group size, contribution dynamics, and earnings. This supports introducing endogenous formation when testing an institutional arc because fixed membership can suppress behavior generated by formation rules. The comparison is bounded. The source studies human membership in public-goods groups, not autonomous agents forming work, and does not test Kaal's reputation, validation, staking, or three-stage substrate. It therefore qualifies the necessity and implementation level of Kaal's evolution stage rather than validating the architecture.

**Holds when.**

- The response is limited to the five page-bound passages and the one mapped Kaal claim.
- External evidence level: peer-reviewed journal-article identity with complete public Indiana University repository full text, plus Crossref, OpenAlex, repository, and DOI landing records.
- Mapping review tier: independent substantive scholarly-growth qualification.
- The source studies human public-goods groups and membership movement, not autonomous agents forming tasks or labor-market matches.
- It varies entry and exit rules and does not test Kaal's reputation, validation, staking, citation, settlement, or three-stage substrate.
- The complete public full text is an Indiana University repository working-paper copy; Crossref and OpenAlex bind the title, authors, DOI, venue, year, and published journal identity.
- Semantic Scholar's direct DOI endpoint returned HTTP 404; identity and publication status were therefore verified independently through Crossref, OpenAlex, the repository record, and the Wiley DOI landing response.
- The evidence supports endogenous formation as a material institutional test dimension, not Kaal's stronger assertion about the exact level necessary or the broader architecture's validity.
