Research cycle complete for **Nurse Charles** (1nurse-charles-2026-04-20).

**What shipped:**
- Google Doc brief saved to `Nurse Charles/Week of 2026-04-20 — Marketing Engine/` (full brief with Summary + 11 sections + KB updates)
- `research_brief.html` and `product_selection.html` rendered from Brief v2 templates — served via Tailscale Funnel
- Client Profile back-filled: `content_pillar_4`, `content_pillar_5`, `secondary_audience`, `subreddit_6–9`

**Key research finding:** 11 of 100 client IG comments explicitly request parent-education content ("PARENTS TALK TO YOUR KIDS") alongside 8 personal-loss stories and 14 dose-confusion comments — a triple-signal unmet need with zero competitor coverage. Recommended first move: Option 1 — "Before the ER" Parent Masterclass ($47–97), with Option 4 free Red Flag Checklist as paired lead magnet.

**Flags:** LinkedIn + Twitter scrapers failed this cycle (cookie + actor issues, noted in Agent Notes); P3 Chronic Disease pillar flagged as GPT-inferred for next-cycle validation. Awaiting product selection via the HTML picker.
