+Review when done. **Caveats to verify in review (flagged in-code as prominent banners + empty
+marker commits 57ca851/8624dee/2aad0aa/539ea47):**
+  - **Task 17 (exec_intent):** `to_exec_intent` needs an EXPLICIT `reference_price` arg —
+    `ShadowDecision` has notional/exposure but NO price field, so qty can't be derived from a
+    decision alone. Integration owner threads the live price (PASS-3 `VenueTick`) at wiring time.
+  - **Task 18 (alpha_data_feed):** intentionally parse/feed-port ONLY — no live NT node / Binance
+    connection in unit code (NT owns its loop; dummy keys; separate feed process). Live node = the
+    integration owner's job. Confirm tests aren't vacuous (parse-fixture, not a live connection).
