1//! DVB CI Extensions (ETSI TS 101 699) — the resource-scoped APDU layer.
2//!
3//! Unlike the EN 50221 application objects (which carry globally-unique
4//! `apdu_tag`s and are dispatched by [`crate::AnyApdu`]), the TS 101 699
5//! extension resources **reuse the same `0x9F80xx` tag values across different
6//! resources** — per Table 87 several resources start their objects at
7//! `0x9F8000`. The same three tag bytes therefore mean different objects
8//! depending on which resource's session they arrive on, so they cannot join the
9//! global `AnyApdu`. This module provides a *resource-scoped* dispatch
10//! ([`CiExtApdu`]): parsing is keyed on the `resource_identifier()` first, then
11//! the leading 24-bit `apdu_tag` selects the object within that resource.
12//!
13//! Each `apdu_tag` const lives in its resource module's `tag` submodule, so the
14//! colliding values are namespaced per resource (`power_manager::tag` vs
15//! `copy_protection::tag` both define a `0x9F8000`).
16//!
17//! Spec: ETSI TS 101 699 V1.1.1 §8, Table 87 (resource IDs + tags) — see
18//! `docs/ci_plus/resource-ids.md`. The per-resource layouts are cited in their
19//! own module docs.
20//!
21//! Resources implemented: Resource Manager v2, Application Information v2, Power
22//! Manager, Event Manager, Copy Protection, StreamInput, ServiceGateway (Generic
23//! Service Gateway), BroadcastServiceGateway, Status Query (+ audience metering),
24//! Application MMI, Download (CAM firmware, + DSM-CC U-N messages), CA Pipeline —
25//! the full TS 101 699 §6 resource set.
