Chain analysis did not need AI to link addresses. Reuse and round numbers were enough, and what improved is how cheaply those heuristics run over everything. For a node, the everyday leak is the peer graph and the IP address. Tor closes only the second half of that. A channel funding transaction is public and ties those coins to your node key for good. CoinJoin for savings holds up, with one caveat worth knowing. Spend two mixed outputs in the same transaction and they are re-linked. Open a channel from one of them and the link is permanent. Mixed coins are quiet money, so daily liquidity is better funded from a source you are willing to have attributed.
