| 1 | //! The one requested → effective reasoning resolver, with provider capability |
| 2 | //! normalization, preserved provenance, and durable receipts that carry |
| 3 | //! **disclosure without content**. |
| 4 | //! |
| 5 | //! Models never auto-switch inside the exact Fleet experience. A worker's |
| 6 | //! provider/model is **frozen and preflighted** before this module runs; |
| 7 | //! everything here only decides how hard that already-chosen model thinks. |
| 8 | //! |
| 9 | //! Resolution order for an exact member: |
| 10 | //! |
| 11 | //! 1. A concrete requested tier resolves to itself, normalized against the |
| 12 | //! route's real capability. **No Router is called** — a manually pinned tier |
| 13 | //! costs nothing. |
| 14 | //! 2. `reasoning = "auto"` **always** goes to the Fleet's attached Reasoning |
| 15 | //! Router (see [`crate::reasoning_router`]). There is no |
| 16 | //! provider-native-adaptive bypass: a route that chooses its own depth is a |
| 17 | //! fact about how the request is *shaped*, not a reason to skip the service |
| 18 | //! the operator configured. A missing or unready Router is an error *before |
| 19 | //! work starts*, and exact Fleets never fall back to the local keyword |
| 20 | //! heuristic or to legacy model routing. |
| 21 | //! |
| 22 | //! Legacy (non-exact) callers keep the old behavior through |
| 23 | //! [`resolve_legacy_reasoning`], which is allowed to use a local heuristic. |
| 24 | //! |
| 25 | //! ## What a durable receipt may hold |
| 26 | //! |
| 27 | //! A receipt is written to journals and events that travel further than the |
| 28 | //! machine that produced them, so it holds **no task text and no routing |
| 29 | //! summary text** — only bounded counts, a truncation flag, a stable hash of |
| 30 | //! the exact transmitted bytes, what redaction removed, and whether the |
| 31 | //! inference crossed provider boundaries. Everything else on it is an id, a |
| 32 | //! model string, a tier label, or a boolean. |
