description: "Vendor-neutral settlement-finality classifier covering three settlement models, each on its own ordered tier ladder: an optimistic challenge window (soft, posted, challengeable, final), a validity proof (soft, committed, proven_unfinalized, final) and single-slot BFT consensus (soft, final). The ladders are deliberately kept separate because a posted batch on an optimistic rollup and a committed batch on a validity rollup are not the same claim, and the ladder actually used is emitted as tier_ladder so the receipt is self-describing. Validity-proof finality is treated as two gates rather than a timer, proof accepted and settlement-layer block finalised, so the in-between position is reported as proven_unfinalized. Adjudicates an asserted finality tier and flags an overstated claim. Chain identity is free text echoed verbatim: there is no chain enum, no named chain profile and no published window table, so the node cannot go stale when a network changes. Evaluation time is caller supplied and the kernel reads no clock. Zero network, zero PII."
