 *   - addresses lowercased so allowlist membership is case-insensitive
 *   - selectors lowercased likewise
 *   - max_value_wei string → bigint
 *
 * Permissive mode tolerates missing strict fields (they're ignored anyway).
 * Strict mode applies defaults: chain_ids must be present; everything else
 * defaults to a closed/zero value.
