//! Module: db::cursor::signature
//! Responsibility: module-local ownership and contracts for db::cursor::signature.
//! Does not own: cross-module orchestration outside this module.
//! Boundary: exposes this module API while keeping implementation details internal.

///
/// ContinuationSignature
///
/// Stable, deterministic hash of continuation-relevant plan semantics.
/// Excludes windowing state (`limit`, `offset`) and cursor boundaries.
/// Hex/display formatting is codec-owned in `db::codec::cursor`.
