segb-core 0.2.0

//! Validation helper: decode and dump Apple Biome `App.MenuItem` records
//! (application name + menu-item text + timestamp) from a SEGB stream.
//!
//! Where `dump_structure` reconciles the *container* (state / timestamp / CRC)
//! against `ccl-segb`, this dumps the decoded *protobuf fields* so the field
//! mapping itself — field 1 = `application`, field 2 = `menu_item` — can be
//! reconciled against the *known* menu selections driven on a real macOS Tahoe
//! system. That closes the gap neither `dump_structure` (container only) nor the
//! iOS corpus (no menu bar) can: `ccl-segb` hands back raw payload bytes, so it
//! cannot be the oracle for the protobuf interpretation — the driven selections
//! are.
//!
//! Only `Written` records carry a live payload (a `Deleted` record's payload is
//! wiped), matching the `segb-forensic` analyzer's Written-only audit.
//!
//! Usage: `cargo run -p segb-core --example dump_menuitems -- <segb-file>`
