++## R2 eviction drills (Media's hot cache)
++
++`scripts/r2-eviction-drill.js` in OpenVibe.Media evicts one VOD's R2 hot-cache copy and proves that the canonical B2 copy serves it, then puts the R2 copy back (docs/object-model.md#r2-eviction-drill there). It refuses unless the B2 and R2 copies match in size and first MiB, and unless the VOD is unheld and not recording.
++
++| Date (UTC) | VOD | Steps | Result |
++|---|---|---|---|
++| 2026-09-25 18:55 | 2178 (3.5 MB, `--pick --max-mb 200`, real `GET /v/2178?raw=1`) | before: served from R2 · evict: R2 copy removed, row → b2 · from B2: served from the canonical copy with the same first MiB · re-warm: R2 copy restored from B2 (HEAD verified), row → r2 · after: served from R2 again; `media_locations` b2 and r2 present. Artifact `/opt/openvibe.media/data/drills/r2-eviction-2178-2026-09-25T18-55-13-212Z.json` | passed |
