Overview

The saved reports for one destination, newest first.

Everything here is best-effort by design: the directory is the operator's, a report may be half-written by a deploy that was killed mid-flush, and a future dash may write a schema this one does not know. None of that is worth a word on a deploy, so an unreadable file is skipped rather than reported.

#prune(count) ⇒ Object

Keeps the newest count reports of this destination and deletes the rest. Other destinations are left alone: they have their own budget, and a staging deploy must not age out production's history.
