Response behavior

- `data.public_page_derived` is `true`. - Preferred methods are ordered first when present: `recency_weighted`, `unweighted`, `single_aggregation`. - Each method exposes forecaster count, the first center/lower/upper value, raw center/bound arrays, and available history point count. - Invalid ids return invalid-parameter errors before upstream IO. - Upstream authentication, challenge pages, missing aggregation data, or parser drift is returned as a typed upstream error.
