Sengi uses labels on statuses to describe them properly:

Definitions

THREAD

X-POST
The status was cross-posted using a software like
MOA.
This functionality is limited to Local TL/Accounts due to API limitation.

REMOTE
The status wasn't federated with your instance and was fetched remotely.
This functionality bypasses the blocking rules of your account/instance, you can disable it in the settings.
