+Vector Zulu — Payment Mirror Adapter
+Polls KoreNet portal feeds for new payment events and executes the full
+payment mirror lifecycle via api.korenet.cloud.
+
+Full lifecycle per VZ runbook:
+  INCOMING SWIFT MT103/PACS.008
+    → MINT mirror tokens
+    → SETTLE T+0
+    → REDEEM fiat
+    → BURN-SELL via venue routing
+    → CLOSE tranche
+    → ANCHOR to Ethereum (ISO 20022 proof)
+    → POST confirmation KoreID back to KoreChain
+
+Dependencies:
+  - vz_mtls_client.py (Bryan's official client)
+  - koreid.py (KoreID generator)
+  - Redis (event deduplication)
+  - Postgres (audit trail)
