**Agenda**
* Minimum depth bar for Reference Architecture and Case Study submissions used as Due Diligence adopter interview substitutes
**Background:** The TOC now lets a published TAB Reference Architecture (and soon, a CNCF Case Study) substitute for an individual adopter interview during project Due Diligence. That only works if RA/case study submissions reliably carry interview grade evidence, and today they don't. Asking the TAB to set a minimum depth bar for submissions.

cncf/toc#2256 (merged) added the original TAB Reference Architecture substitution to the TOC's Due Diligence guide: a project's inclusion in a published RA "may serve as a replacement for an individual adopter interview."

cncf/toc#2282 (open) extends the same substitution to CNCF Case Studies, with the same "may serve as a replacement" language.

Neither the merged DD guide text nor the TAB's own RA submission process currently requires any minimum depth for a submission to count as adopter interview equivalent evidence, and there's no cap on how many of the required interviews a single project can satisfy this way.

***State of open Reference Architecture submissions.** 8 currently open:

Goal: go through each, decide what's actually moving versus what needs to be closed or reassigned, and clear as much of this backlog as we can before KubeCon NA (Nov 9).

_Carried forward from #148 (2026-08-24 meeting had no quorum; 2026-08-31 skipped as a 5th Monday; 2026-09-07 skipped as Labor Day)._

Start by reviewing cncf/toc#2256 and cncf/toc#2282, then inspect the open Reference Architecture issues listed in this agenda. Done means the TAB has decided the minimum evidence depth, any limit on substitutions, and which submissions should be closed or reassigned before KubeCon NA.
