Creator ── publishModel() ──► ModelRegistry ─► IPFS (metadata + ONNX)
             │                              │
Buyer ── purchaseModel() ──► PurchaseMgr ─► AVM → Creator + PlatformFee
                                             │
                                      AccessToken issued → IPFS fetch
