Research direction

No source files, tests, or entry points are named. Start by tracing how Keytrace verifies claims against the PDS records shown in the issue, then establish whether same-account claims should be treated as verified by default and define tests for the chosen behavior.

Written by the indexing model from the issue text.

Description

Playing with Keytrace I realised that for any service which stores its data on my PDS, the claim can be verified by querying the PDS directly – and by the same token, the claim will never truly be bidirectional.

For example, the two sides of my Tangled claim are saved on my PDS at:

  • at://did:plc:6cbrxnrfmwpb7rhjkihqezzh/dev.keytrace.claim/3mtpfsbdp5h2j
  • at://did:plc:6cbrxnrfmwpb7rhjkihqezzh/sh.tangled.string/3mtpfmtkpwj22.

I'm not sure how problematic this is, bus so far as I can see it is unavoidable.

What it does seem to imply though is that the second part of the claim is entirely unnecessary. For any claim relating to the same ATProto account as my Keytrace profile, it may as well be considered "verified by default" without needing to publish the other half of the claim.
