Function gen_session_data

core/tests/test_persisted_schema_roundtrip.rs:498–542

The largest persisted root type, and the carrier of the 3.3.0 identity fields (tenant/principal/template/correlation). Exercises a nested `PermissionPolicy` (itself holding the persisted untagged `PermissionRule`), the `#[serde(alias = "todos")]` `tasks` field, and the `#[serde(skip)]` `hook_engine` (safe: skipped in both directions).
