| 1 | //! Single source of model facts for CodeWhale (#3071, #3073). |
| 2 | //! |
| 3 | //! Historically, "what is this model's context window / max output / does it |
| 4 | //! reason?" was answered by several hard-coded sites: |
| 5 | //! |
| 6 | //! * [`crate::models::context_window_for_model`] / |
| 7 | //! the models module's context-window lookup for context windows, |
| 8 | //! * [`crate::models::max_output_tokens_for_model`] for output caps, |
| 9 | //! * [`crate::models::model_supports_reasoning`] for the reasoning flag, |
| 10 | //! * the `DEFAULT_*` model-id constants in `crates/config/src/lib.rs` for the |
| 11 | //! canonical model each provider ships by default. |
| 12 | //! |
| 13 | //! This module is the **foundation** for collapsing those into one place: a |
| 14 | //! [`ModelMetadata`] registry keyed by model id, plus a single [`lookup`] |
| 15 | //! entry point. It is intentionally *additive* — the existing call sites are |
| 16 | //! left untouched in this pass and will be migrated to consume the registry in |
| 17 | //! a later change (so behaviour is unchanged today). |
| 18 | //! |
| 19 | //! ## Seeding discipline (no drift) |
| 20 | //! |
| 21 | //! The registry does not re-declare context-window / max-output / reasoning |
| 22 | //! numbers. Instead it **seeds** each entry by calling the existing |
| 23 | //! `crate::models` functions, so the registry can never silently disagree with |
| 24 | //! `models.rs`. The canonical model ids come from the same provider defaults |
| 25 | //! the config crate ships (see [`SEED_MODEL_IDS`]). The |
| 26 | //! The `registry_context_window_matches_models_rs` drift guard then |
| 27 | //! re-asserts the equivalence for a sample so that if a future change replaces |
| 28 | //! a seed with a hard-coded literal, CI catches the drift immediately. |
| 29 | //! |
| 30 | //! Production consumers: [`crate::model_profile`] (capability bridge), |
| 31 | //! `crate::tui::model_picker` (picker hints), and |
| 32 | //! [`crate::fleet::capability_badges`] (Fleet setup/roster badges, #5038). |
