Pre-existing behaviour; the PR only hoists cost derivation into a shared `EntryCostInfo`. +- **#2854 route reason.** `routeResult()` sets `routeReason` to `blocked-model-redirect`, and the policy and combo paths overwrite it with `policy-selected` and `combo-pick`. Real, but not a defect: `route.modelId` already carries the replacement model, so dispatch is correct and only the diagnostic label is lost. `routeReason` has no behavioural consumer — it feeds the decision trace and an alias-logging branch.
