# Current step · V387

Implementation, numeric verification and the bundled 5.6 actual skinned-mesh temporal render are complete.

The permanent 5.6 regression command is:

```bash
node tools/nexprod/run_v387_5_6_local_render_gate.mjs
```

It must reproduce the V386 known-failing control and generate the V387 two-loop film/contact sheets before any future animation change is accepted.

The remaining parity gate is actual-scene temporal Chromium/OpenGL QA:

1. Load the V387 resolved player through localhost using the supplied runbook.
2. Record at least two complete loops at normal playback speed.
3. Inspect both transitions frame-by-frame: neutral → approach → grip hold → release.
4. Confirm natural hand neutral, animated shoulder lowering, stable peak grip and smooth release on both sides.
5. Return the film plus a temporal PASS/FAIL report.

Static peak screenshots alone cannot approve this version.

Stop boundary: do not modify V385 peak transforms, lower-body motion, generic grip authority, runtime ownership or production solver policy during this QA.
