An atomic swap is not instant by design. Each side has to publish a transaction and wait for the other chain to confirm it, so the time it takes is set mostly by the block spacing of the two chains involved rather than by anything either party does.
Nothing was lost. The payment was never claimed: it was spent without the preimage, after the timelock, which is the refund path back to the payer, in 9bbad0d67e0d2f614cf1921c1577ac55001a072732f62483fd2f5f0d137e4539.
The swap stopped at TakerPaymentSpendFailed. The maker's claim on the taker's coin was rejected; it can be retried for as long as that payment is unspent.

Recorded by the swap's own protocol log, which is the only source that knows: the aggregator reports failed and completed swaps identically. Nothing changed hands, so it sets no reference price.

No flags are stored against this swap. Flags are written while a swap sits inside a live pricing window, so on an older swap their absence means it was never assessed rather than that it was assessed and found clean.
