Nothing to fix in 26 — the three-way identity is verified.
Not starting the history layer: it is a ~10-signature refactor of how
transcripts resolve, at the end of a long session, in the path whose failure
mode is a member reading the owner's conversations. That is the shape host
talked me out of earlier tonight, and the same argument applies whether or not I
am the one making it. Tomorrow, after deprovisionOsAccount.
Everything mechanical for a member turn is done and inert: provisioning, the
login probe, agent-status, the privilege drop, the SDK wiring, session
ownership, the six scoped commands, member populated, three-way turn identity,
the rejection backstop. Both gates up, member unreachable in production.
