Build: Conflict Detection & Family Member Tags

Status: 🟡 IN PROGRESS

Problem Statement

Matt rescheduled "Sullivan Dentist Appt" to Sat May 02 — same day as "Family Movie Night" — but no warning appeared. Also, day label didn't update (still showed "Fri May 01").

What We Need

Backend (Socrates)

1. Person-level conflict detection
   - Events have family_members array (e.g., ["Sullivan"])
   - When event A overlaps with event B, check if any member is in both
   - Return conflict list in API response

2. Day label auto-recalculation
   - day_label should be computed from start date on every read
   - Not stored statically in JSON

Frontend (Daedalus)

1. Conflict badge on event cards
   - Shows "⚠️ Double-booked with: [event names]"
   - Different severity: same-person = red, same-day = yellow

2. Family member tags
   - Small pills showing who's involved: 👤 Sullivan, 👤 Harper, 👤 Aundrea
   - Color-coded by person

Integration Checks

• [ ] API returns conflicts array with overlapping events
• [ ] API computes day_label dynamically
• [ ] Event cards show conflict warnings
• [ ] Event cards show family member pills
• [ ] HTMX swap preserves conflict state

File Mapping

Agent	File	Destination
Socrates	backend/event_conflict.py	Logic for conflict detection
Socrates	backend/router_patch.py	Updated /api/events-dashboard endpoint
Daedalus	frontend/events.html	Updated template with pills + warnings
Daedalus	frontend/style_patch.css	CSS for pills and conflict badges

Notes

• Test data needs family_members field added
• Conflict detection: naive date overlap (same day = potential conflict)
• Future: time-based overlap, not just date
