Replay Evidence
same_conditions
Original amount, route, peer state, fee limit, timeout, and asset unchanged
The original failure reproduces under the same conditions, confirming the fingerprint is stable.
alternate_route
Selected alternate route excluding the failing condition
A route with different hops avoids the original failure point with slightly higher latency.
split_payment
Split payment into 125 CKB + 125 CKB
Split payment does not resolve this failure fingerprint.
