The finding
- The trough is the gate: at 41% two-or-more-credential coverage, a passkey-only cutover is a support incident wearing a security announcement, and the platform says so before it happens.
- The override exists, is explicit, and is attributed. A platform that cannot be overridden gets worked around; one that records who overrode it gets argued with instead.
- Removing the legacy path is logged as irreversible, because a tenant that can quietly switch the password back on has not actually made the phishing-resistance claim true.
What the set answers it with
- Three coverage figures per tenant — any credential, two or more, still legacy-dependent (view 18).
- The impact-analysis gate in the release pipeline, which counts the users a policy change would lock out (view 17, ADR-11).
- Recovery-path cost reported as its own line, since that is where the cutover's real cost lands (ADR-13).
Assumptions
- 2.1 million end users for the illustrated tenant; 41% holding two or more credentials at the point of the request.
- A cutover threshold is tenant-set rather than platform-set, because the acceptable lockout rate is a business decision.
