Diagnose referral-epic scope drift: non-referral decision logs in td-00e401

**Why this matters:** The Referral Team epic currently contains open non-referral decision-log tasks (`td-d80972`, `td-e0b508`, `td-909a7f`) that dilute referral prioritization and review throughput. Without scope cleanup, queue signals for Glenn's team are noisy and PM status tracking is less reliable. **Scope:** Audit all open/in-progress descendants of `td-00e401`, classify each as referral-core vs adjacent/non-referral, and propose explicit actions per item (keep, re-parent, or close). Publish a concise recommendation brief and update `projects/referral-team/overview.md` accordingly. **Source signal:** 2026-04-13 live `td` sweep; open descendants include affiliate/theme and changelog decision records under referral epic.
