Moving a tier between estates

Abstract

A portfolio tier moves from an established estate to a hub-and-spoke one through a fixed sequence. Each step names what it needs, the readiness gate wants a rehearsed way back and the owner's approval, and the old path closes only after someone independent signs the verification.

Build the new path before closing the old one, and keep the way back open until verification is signed.

Try to break it

A claim stands because the attacks on it were attempted and refused. Each one runs against the instrument's own rules. 0 of 4 attempted · 0 refused

Land before the gate
The tier moves while its evidence is still under review.
Pass the gate without a rehearsed rollback
The owner approves; nobody has run the way back.
Retire the old path while soaking
The new path looks fine, so the old one is closed early.
Roll back after the old path is gone
Something breaks after retirement and the old path is wanted back.

Declared limits

The sequence is the shape of the practice, not a programme's runbook; no estate is named.
Generic and illustrative throughout: the behaviour is shown, the internals of the systems it is drawn from are not.
