David debugged: Investigated why new signups had zero lecture candidates appearing on home page

After signing up with a test account (Keno), David noticed the home page stayed empty:

i did a sign up with keno and the courses detection failed open to his latest 6, why? is ti cause the calendar detection completed after the courses did the process where they check to see which coruses aare current or not? further, i waited on the uni app home page to see if candidates for elcture notes/assignments would appear, and none did! what hapepned? we need them to be appearing as the module planners complete

The investigation found that candidate generation was sequential on module planner completion rather than incremental, and that calendar agent failures (all six courses) were masking the downstream candidate pipeline. David dispatched parallel subagents to investigate lecture and assignment candidate generation separately for that signup.
