Ledger Consensus Finality Classifier

Classifies a ledger-consensus position under a deadline-bounded-inclusion model (XRPL) or a federated-BFT model (Stellar SCP). Neither model fits a monotone tier ladder: XRPL resolves to one of several terminal branches (final success, a terminal tec fee-consuming failure, provable non-inclusion, or an unprovable-absence gap) with no rank between them, and Stellar SCP has no reorg tier at all once a transaction is externalized. The machine-readable field is an outcome branch, not a rank. If a counterparty asserts an outcome the evidence does not support, the claim is flagged as overstated.

Ledger Consensus Position
Settlement model
Chain label (free text, echoed)
Free text only. This tool holds no chain list and no embedded validator-list (UNL) snapshot, so it cannot go stale when a network's validator set changes.
as_of_ts (epoch seconds, caller supplied)
The kernel never reads a clock. Evaluation time is an input so the result is reproducible.
Required tier (corridor policy cutoff, model outcome vocabulary)
Claimed tier (optional, what a counterparty asserts)
Deadline-Bounded Inclusion Parameters (XRPL)
submitted_at_ledger
last_ledger_sequence
included_in_ledger (blank = none)
ledger_validated
result_class
highest_validated_ledger
continuous_history_ok
continuous_history_ok is caller-attested: whether the server holds gap-free validated ledger history over the submission-to-deadline range. The kernel cannot verify this itself (no network); its absence is exactly what ABSENCE_PROOF_INCOMPLETE flags.
Federated BFT Parameters (Stellar SCP)
externalized
quorum_slice_trust_ok
issuer_clawback_enabled (optional)
time_bounds_max (optional, epoch seconds)
SCP has no reorg path once externalized: there is no pending-to-final challenge window to express. The residual risk is quorum-slice topology trust and, where clawback is enabled, issuer-level asset authority; neither is a consensus property.

    ART-492 Settlement Finality Classifier covers three L2/L1 finality shapes with a monotone tier ladder (optimistic challenge, validity proof, single-slot BFT). This node covers ledger-consensus models with bidirectional or terminal-branch outcomes instead: XRPL's deadline-bounded inclusion and Stellar SCP's federated BFT.

    Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.
    
  
    Run the AINumbers MCP tool `classify_ledger_consensus_finality`. Task: Classify a ledger-consensus position under deadline_bounded_inclusion (XRPL) or federated_bft (Stellar SCP) and flag an overstated finality claim.
Call it with arguments: {"policy_parameters":{"settlement_model":"deadline_bounded_inclusion","as_of_ts":1753000000,"last_ledger_sequence":1000,"submitted_at_ledger":990,"included_in_ledger":995,"ledger_validated":true,"result_class":"tes","highest_validated_ledger":996,"continuous_history_ok":true,"required_tier":"final_success","claimed_tier":"final_success","chain_label":"XRPL mainnet"}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
