As a result, invoices paid via this channel have alias: local stored as short_channle_id for their HTLCs:

$ lcli listinvoices
...
 {
         "label": "test4",
...
         "payment_hash": "8c451777f7b0a93b1a6f1d58280a6d01dff8bd36c6d561c270250ac69001a73f",
         "amount_msat": 100000,
         "status": "paid",
...
}

$ lcli sql -k query="SELECT short_channel_id, payment_hash, state FROM htlcs WHERE payment_hash=x'8c451777f7b0a93b1a6f1d58280a6d01dff8bd36c6d561c270250ac69001a73f';"

         "SENT_REMOVE_ACK_REVOCATION"
      ]
   ]
}

$ lcli listpeerchannels | grep short_channel_id

Ok, I figured this out. It is a private 0-conf channel... I forgot I had it ))
