Scenario:

• Add some commits authored with an identity A that will get assigned to user X and some authored with an identity B that will not get assigned to anyone.
• Explicitly unassign identity A from user X.
• Explicitly assign identity B to user X.
• Go to user X's commit list from the user X's profile page or craft a query for Diffusion commits, specifying X as author.

Expectations:
Commits A are not returned, commits B are returned — reflecting current state of identity-user mappings.

Reality:
Commits A are returned, commits B are not returned — reflecting the state of affairs at the time of indexing the commits.

Screenshots (from comment):

Here, I assigned one of your identities to myself:

Now when you go to the list of your commits, there is some entry from "me", but there shouldn't.

And when you look at my commits, there are none — but there should, as this commit is now mine, as far as Diffusion is concerned.

Note that this maintenance script seems to do not cover the above fixes:

./repository rebuild-identities --all-identities
