 # Next Session — Pick Up Here
 
-## 1. Generate Logo Images
-Use these prompts in DALL-E / Midjourney / any AI image generator:
+## ✅ Completed This Session (June 9)
 
-**Logo:**
-> A minimal, professional logo for "Sleep IQ" — an AI sleep health companion. A crescent moon cradling a brain wave pattern that subtly forms a checkmark. Deep navy and soft indigo palette with a violet-blue gradient accent. Clean, medical-grade aesthetic. No text, just the symbol. Vector-style, flat design with subtle glow. White background.
+### Logo & Images
+- [x] Generated all 4 images (Logo, Hero, Architecture, Social) via LLM prompts
+- [x] Logo swapped into `ui_template.py` (replaced "Z" placeholder → `<img src="/static/logo.jpeg">`)
+- [x] All 4 images stored in `static/` folder and pushed to GitHub
+- `IMAGE_PROMPTS.md` has the original prompts; `AGENTS_LEAGUE_CONTEXT.md` can be used as context input for better prompt generation
 
-**Hero Image (Innovation Studio submission):**
-> A modern split visualization of sleep health AI. Left: a dark bedroom with a person sleeping, a CPAP machine glowing softly blue, and a smartwatch on the wrist. Right: a flowing dashboard with charts, AI analysis, and floating medical citation cards. Deep navy and indigo palette with violet gradient accents. Cinematic lighting, 16:9 aspect ratio.
+### Bug Fixes
+- [x] **Flags/Observations not updating** when switching data sources — fixed `switchSource()` and `fetchWithFilters()` to call `renderFlags()`
+- [x] **Same-source upload merge** — uploading two watch files (e.g., Jan + Feb) now merges records, dedupes by date, and recomputes stats
+- [x] **Source tag layout** — fixed horizontal stretching (removed `display:flex` conflict), DEMO badge is now compact
 
-## 2. Replace Logo in App
-Share the generated logo image → I'll replace the "Z" in `ui_template.py`
+### Multi-Source UX
+- [x] **"+ Add another data source"** always visible, even in multi-source mode
+- [x] **Source tabs** with active highlighting + **× remove button** per source
+- [x] **"Clear all"** button resets everything to upload screen
+- [x] **DEMO badge** (yellow pill) shown on demo data sources
+- [x] Backend: `/api/remove-source` and `/api/clear-data` endpoints
+- [x] Backend: `is_demo` tracking per data source
+- [x] Backend: `_demo` suffix on source keys (e.g., `cpap_demo`, `fitbit_demo`)
