"""网格编辑（局部重拓扑）— local_edit on a 智能网格 (Nexus) model.

    tripocli edit -p <project_id> --bbox "-1,-1,-1,1,1,1" --face-limit 8000 --wait

The studio shows this as the 「编辑」 tab: pick a bounding box on a Nexus mesh and
re-topologise just that region.  Verified body:
``{project_id, source_operator_id, bbox:[[min],[max]], face_limit}``.

⚠️ Only offered for **智能网格 (Nexus)** models that are not yet textured / rigged
/ segmented / PBR (the studio hides the tab otherwise).  ``bbox`` coordinates are
normalised to the model's own space, ``-1..1`` per axis (the UI clamps them), so
the default ``-1,-1,-1,1,1,1`` covers the whole model.
