 2026-10-11: Platform independently re-agreed the final amended design (session proposal SHA25623f13d2a5a4204f749f35c5d44ef39d213838cd2fce1c36fb4775254ef1c7f09). Original conditional review and narrow confirmation are retained in railiance-platform/docs/reviews/2026-10-11-keycape-openbao-negative-session-owner-review*. Source acceptance T01 is complete; actual registry/leeway/readiness, founder live go, negative/cleanup and separate capability/no-fallback obligations remain T02 and owner plans.

+acknowledgment): the [infrastructure assessment](../../the-custodian/docs/changes/netkingdom-target-2026-10-17/key39-infra-finalization-r1/ASSESSMENT.md)
+confirms all 14 executable/test/producer-decision pins and three Platform source
+pins still match. Source reviews remain complete: T01/T03 done, T02 wait. Existing
+source acceptance, resolved registration go caafe4be and the standing attended
+rule remain valid; no new protocol or blanket approval request is needed. The
+remaining sequence is KEY-WP-0038-T02/T03 first-case registration/claims proof,
+admission of the existing coding-client proposal with sanitized owner readiness
+returns, then one attended negative/revoke/cleanup receipt committed with probe
+clients removed. No native acceptance or credential/registration action is
