@PortaFed

I have a couple of comments regarding the spec https://codeberg.org/portafed/portafed/src/branch/main/portafed-spec/spec.md

It contains a comparison with FEP-ef61, but it is not quite correct:

- FEP-ef61 identity is not actor-rooted. The closest equivalent of FEP-ef61 identity in normal ActivityPub is a server with a domain name. A single FEP-ef61 authority can manage multiple actor documents.
- FEP-ef61 does not lack a migration flow. Strictly speaking, it doesn't need one, because data is not attached to a server and can be continuously synchronized between multiple servers. But a more familiar migration flow is also possible via outbox export-import.

@benpate That would be great and happy to contribute wherever it fits.
My guess on the scope decision is the same as yours: hostile-server recovery is genuinely harder, and a cooperative spec is already a lot to get right. Makes sense to tackle it separately.
Take your time reading. I'll put together a short write-up of how MigrationProof could slot into the existing spec easier to react to something concrete than to an abstract pitch.

@jonny@neuromatch.social tracks doesn't it 😝

Can't make heads or tails of this one

@PortaFed That's awesome. Let's work you into the existing effort. We could use all the help we can get.

Also: I'm pretty new to the data portability spec; so I know that "hostile server" is out of scope, but I wasn't there to know why that choice was made. I'm *guessing* is was too much to tackle at the time.

But one way or another, it would be great to have something in place for this situation, too.

I still need to read your work fully, so I understand what we're talking about :)

@benpate Yes, that’s exactly the gap I’m aiming at: the case where the old server is gone, hostile, or unavailable, and the user needs some way to carry forward verifiable account state without relying on that server’s cooperation.
My reading is that LOLA covers the cooperative portability path well, while this harsher failure case still needs more work. I don’t see PortaFed as a competing standard so much as a possible building block for that scenario.

@PortaFed ~ do you think these ideas would work alongside the existing work being done by the W3C social web community group? https://swicg.github.io/activitypub-data-portability/lola

I *think* you're solving the issue of "my server disappeared, I don't have a backup, and I can't prove I'm still me." Is this close?

Because that's the one use case that the portability spec DOESN'T do. So, maybe there's a way for us to work together, instead of making competing standards.
