What it is
A clean pattern for using a slow, accurate detector inside a fast loop.
What it does: Tracks a named object live; flow handles motion, Jev corrects absolute position.
Why it belongs in the showcase: Shows how to hide decision-model latency with classic filtering.
Caveats: Preview Box feature; per-call cost.
Evidence
Public Apache-2.0 Python package (5★ at intake) created 2026-10-16. README explains Lucas-Kanade + RANSAC flow inside the box between answers, a history buffer that rewinds the filter to frame k when its Jev box arrives, a `jev-box-track "iPhone"` webcam demo, and a `JevTracker` library whose `update()` never blocks on the network. Reads TYPESAFE_API_KEY from env.
Caveats
- Box is a preview feature in Jev 1.14; accuracy varies with object size
- One API round trip per Jev answer; cost scales with frame sampling
- Small new repo; test on your own camera and targets
