trusty-mpm 1.0.2

//! Unit tests for `SessionManager::set_deliverable_id` (DOC-35 §10.6, #2379).
//!
//! Why: split out of `tests.rs` rather than grown further, mirroring the
//! established `set_source_id_tests.rs`/`restart_tests.rs`/`reactivate_tests.rs`
//! sibling-test-file pattern.
//! What: the happy path (persists and round-trips through `get`) and the
//! missing-session path (a typed `SessionNotFound`, not a panic or silent no-op).
//! Test: this file IS the test module; run with `cargo test -p trusty-mpm`.
