Two causes of the "every message I send shows up again as a reply from the peer":
1. Harvest bug — the full-refresh path fed a SENT tx's outgoing memos (from
z_viewtransaction outgoing outputs) into the chat metadata extractor, and
ChatService::ingest marks everything Incoming. So each send was re-ingested as
a phantom "from peer" message. The recent-refresh path already omitted this, so
it was accidental. Drop the outgoing chat-harvest (keep the tx-history harvest);
genuine incoming still comes from z_listreceivedbyaddress, and our sends are
recorded by the local echo.
2. Own-identity ingest filter — a memo whose sender public key equals our own
identity is by definition something we sent (only we hold our key); it must
never be ingested as incoming. Skip those in ingest. This also collapses
same-seed self-chat (running the SAME wallet in the full node and Lite makes
them one chat identity, so sends land on an address we also own and loop back).
For a real two-party chat use two DIFFERENT wallets/seeds — same-seed wallets are
one identity and can't be distinct peers.
