| """Harness B: route a scene's on-disk explicit spatial code -- as TEXT, | |
| no video frames -- to all three models, for every VSI-Bench question. | |
| Reuses harness.A's model registry/adapters and fixed generation protocol exactly; only | |
| what is fed to the model differs (spatial-code text instead of frame images). Results | |
| are written in the identical per-question JSON shape harness.A uses, so B's records are | |
| directly comparable to A's -- the frame-provenance fields are simply replaced with | |
| spatial-code provenance fields (see harness.B.run._build_record). | |
