"Final at window Y" as deterministic, replayable evidence for a shared-ledger tokenized-deposit transfer. Settlement-asset finality-regime classification, Linea L2 finality-window classification, and an on-chain cash-leg finality check compose into a settlement-orchestrator ship-readiness attestation, then anchor as an eIDAS Art.41-aligned electronic timestamp. Built for the correspondent bank or auditor needing replayable evidence that a shared-ledger transfer is final at a stated window — not for asserting on-chain settlement this chain did not observe.
receipt://{execution_hash} resolver link is a planned upgrade (rides the N1 MCP Resources work) and is not yet present in the exported artifact.classify_settlement_asset_finality{
