+# Session Log: Chris Knight Email Verification for Cascades
+
+## User
+- **User:** Howard Enos (howard)
+- **Machine:** Howard-Home
+- **Role:** tech
+
+## Session Summary
+
+Howard reported that the night person at Cascades (Chris Knight, Controller) sent him an email expressing concern about a suspicious sender. The task was to locate the email and verify whether it was legitimate.
+
+Initial search checked Mike's mailbox (incorrect assumption based on userEmail context hint). Howard corrected that his mailbox (howard@azcomputerguru.com) was the target. The email was found: Chris Knight forwarded "FW: Doc Package | Cascades Retirement Properties, Inc. | 106513" at 5:05pm MST (2026-07-18T00:05 UTC). The original email was from Michael Rosales (michael.rosales@smflus.com) at Sumitomo Mitsui Finance and Leasing, notifying Cascades that DocuSign loan documents were incoming with access code 106513.
+
+Full email header analysis and DNS verification of smflus.com confirmed legitimacy: enterprise Proofpoint MX, strict SPF (-all), two DocuSign TXT verification records on the domain, and the original email passed SPF/DKIM/DMARC at every hop. The only DKIM failure was at the final hop where INKY/GuruProtect modified the body to inject its banner (expected behavior). A response was drafted addressed directly to Chris Knight and sent to Howard's Discord for forwarding.
+
+## Key Decisions
+
+- Verified sender domain (smflus.com) via DNS rather than relying solely on email content -- MX, SPF, TXT (DocuSign verification), and DMARC records all checked.
+- Analyzed full email authentication headers (ARC chain i=1 through i=4) to distinguish legitimate authentication from INKY-induced DKIM body hash failure.
+- Drafted the response addressed to Chris Knight directly (second revision per Howard's request) so Howard could paste/forward it without editing.
+
+## Problems Encountered
+
+- Initially searched Mike's mailbox instead of Howard's. Howard corrected the target mailbox. The userEmail context hint showed mike@azcomputerguru.com but the operator was Howard.
+
+## Configuration Changes
+
+None.
+
+## Credentials & Secrets
+
+None.
+
