public sealed class BodyHistory

The last few poses of one body, oldest first.

No guide page documents this yet — the page shows what the code says about itself.

Remarks

The same shape as CaptureRing in the replication layer and for the same reason — a fixed ring, written round, allocating once — but keyed and searched differently. That one is looked up by an exact tick, because a delta names the capture it was measured from. This one is looked up by a tick that falls between two entries, because nobody saw the world on a tick boundary.

Ticks are modular, so this cannot be a binary search. A Tick has no ordering — Tick's own remarks explain why it refuses to have one — and the ring holds at most a couple of dozen entries, so it is walked. Sorting or bisecting a modular sequence is the bug that reproduces once every two years of uptime.
