"""
Codebook (universal annotation feature).

A mutable, optionally nested set of codes (labels) backed by the
universal `project.sqlite`. Opt-in per scheme via
`annotation_schemes[].codebook: true`; `codebook_mode`
(fixed|extensible|open) governs whether annotators may add codes on the
fly. Universal — usable in standard annotation, solo mode (human + LLM
co-edit), and QDA mode.

Layers:
- `store`    — SQLite persistence (codes + annotation_codes).
- `codebook` — read-model: tree + flat label list for the schema bridge.
- `service`  — the single audited mutation path (create/rename/recolor/
  move_under/delete + annotation links); fires change listeners (ICL
  prompt-cache invalidation).
