- Auth: none declared

Classifies a tokenized-deposit transfer’s finality risk given L2-batch to L1-settlement timing: soft (unsubmitted), batched (submitted, not yet final), or l1_final tier, reorg-window risk, and a safe-to-release verdict against a corridor policy cutoff. Fills the L2 gap classify_settlement_asset_finality does not cover. Classifies supplied state only, never observes the chain or an RPC. Draft-pinned generic optimistic/batched L2 model; Linea-specific published finality windows were not found at STEP-0 re-verify (2026-07-13). Not check_cash_leg_finality or classify_settlement_asset_finality.
