History windows

How far back each tier may read on each route; what happens past it.

Each route has a history cap per tier: how many days back from (and to) may reach. Asking further back answers 422 window_too_large; the message says the cap. "All recorded" means the API sets no cap of its own (the source's own depth still applies).
