+## Progress Updates
+
+### [2026-04-10] ICS/SCADA & IMAP Bait Completion
+The following infrastructure gaps from the Bug Ledger have been successfully resolved:
+* **#7 (IMAP/POP3):** Both services now implement full protocol state machines (authentication, selection/transactions, fetching) and serve realistic hardcoded bait payloads (AWS keys, DB passwords).
+* **#10 (MQTT):** The service now issues successful `CONNACK` responses, presents interactive persona-driven topic trees, and logs attacker `PUBLISH` events.
+* **#11 (Conpot):** Wrapped in a custom build context that correctly binds Modbus to port `502` using a temporary template overwrite, resolving the missing Modbus response issue.
