Linea L2 Finality Window Classifier

Classifies a tokenized-deposit transfer's finality risk from supplied L2-batch and L1-finalization state: soft (unsubmitted), batched (submitted to L1, not yet final), or l1_final. Returns reorg-window risk and a safe-to-release verdict against a corridor policy cutoff.

Generic Optimistic/Batched L2 Model Draft-Pinned, Not Linea-Confirmed Classifies Supplied State Only

What this does NOT prove
This kernel never observes a chain or an RPC endpoint. Its three-tier ranking is a generic optimistic/batched L2-to-L1 model; Linea-specific published finality windows were not found at SLI-WAVE-1's STEP-0 re-verify (2026-07-13) and this classification is draft-pinned, not a claim of conformance to Linea's own published finality guarantees.

This check reports three states. It cannot express the position where a validity proof has been accepted but the settlement-layer block carrying it is not yet finalised, which is a real and distinct state because validity-proof finality is two gates rather than one timer. ART-492 Settlement Finality Classifier is vendor neutral, takes the window and finality parameters as inputs, and reports that in-between position as proven_unfinalized. This page stays live and unchanged, so receipts it has already produced remain verifiable.
