+## Shared Corp v1 System Login
+
+When an authorized task requires login to a Corp v1 system being built or operated, follow the shared policy in `corp-v1--main` and use only the Bitwarden-injected runtime secrets named:
+
+```text
+HL_V1_SSO_EMAIL
+HL_V1_SSO_PASSWORD
+```
+
+Secret availability is capability, not authorization. Verify the destination origin and task purpose before login. Never print, inspect, log, hash, serialize, paste, screenshot, or persist either value; never place a value in a command line, URL, file, repository, prompt, Discord message, browser console, test fixture, CI output, or generated artifact. Never ask a human to paste a value into chat. If a variable is unavailable, report only its missing name and request Bitwarden/gateway injection. Login does not authorize account recovery, MFA or credential changes, permission changes, billing, spending, destructive operations, or access outside the approved project task.
