+# ThreatHunt — Session Update (February 19, 2026)
+
+## Summary
+
+This session covered 6 feature improvements and bug fixes across the ThreatHunt platform, all deployed via Docker Compose.
+
+---
+
+## 1. Network Map — Clickable Type Filters (IP / Host / Domain / URL)
+
+**Request:** "IP, Host, Domain, URL on the network map… can I click on these and they would be filtered in or out"
+
+**Changes (`NetworkMap.tsx`):**
+- Legend chips (IP, Host, Domain, URL) are now clickable toggle filters
+- Added `visibleTypes` state (`Set<NodeType>`) and `filteredGraph` useMemo that filters nodes + edges by visible types
+- Active chips: filled background with type color, fully opaque
+- Inactive chips: outlined with type color, dimmed at 50% opacity
+- Each chip shows node count for that type, e.g. `IP (42)`
+- At least one type must stay visible (can't disable all four)
+- Stats chips (nodes/edges) update to reflect the filtered view
+- All mouse handlers (pan, hover, click, wheel zoom) updated to use `filteredGraph` instead of raw `graph`
+
+---
+
+## 2. Network Map — Cleaner Nodes (Brighter Colors, 20% Smaller)
+
+**Request:** "Clean up the icons, the colours are dull and the icons are too big in the map… shrink by 20%"
+
+**Changes (`NetworkMap.tsx`):**
+- Colors bumped to more saturated variants:
+  - IP: `#60a5fa` → `#3b82f6`
+  - Host: `#10b981` → `#22c55e`
+  - Domain: `#f59e0b` → `#eab308`
+  - URL: `#a78bfa` → `#8b5cf6`
+- Node radius shrunk ~20%:
+  - Max: 22 → 18
+  - Base: 5 → 4
+  - Multiplier: 2.0 → 1.6
+
+---
+
+## 3. Dataset Viewer — IOC Column Highlighting
+
+**Request:** "I'm looking at one of the datasets and 4 IOCs are showing… but I can't see it… is there a way to highlight that"
+
+**Changes (`DatasetViewer.tsx`):**
+- IOC columns in the DataGrid are now visually highlighted
+- **Header:** colored background tint + bold colored text + IOC type label (e.g. `src_ip  ◆ IP`)
+- **Cells:** subtle colored background + left border stripe
+- Color-coded by IOC type matching the Network Map palette:
+  - IP — blue (`#3b82f6`)
+  - Hostname — green (`#22c55e`)
+  - Domain — amber (`#eab308`)
+  - URL — purple (`#8b5cf6`)
+  - Hashes (MD5/SHA1/SHA256) — rose (`#f43f5e`)
+- Added `IOC_COLORS` mapping, `iocTypeFor()` helper, and dynamic `headerClassName`/`cellClassName` on DataGrid columns
+- CSS-in-JS styles injected via DataGrid `sx` prop
+
+---
+
+## 4. AUP Scanner — "Social Media (Personal)" → "Social Media" Rename
+
+**Request:** "On the AUP page there is Social Media (Personal) — can we remove personal, it's messing up with the formatting"
+
+**Changes (`keyword_defaults.py`):**
+- Default theme key renamed from `"Social Media (Personal)"` to `"Social Media"`
+- Added rename migration in `seed_defaults()`: checks for old name in DB, if found renames via SQL UPDATE + commit before normal seeding
+- Backend log confirmed: `Renamed AUP theme 'Social Media (Personal)' → 'Social Media'`
+
+---
+
+## 5. AUP Scanner — Hunt Dropdown (previous session, deployed)
+
+- Replaced individual dataset checkboxes with a hunt selector dropdown
+- Selecting a hunt auto-loads and selects all its datasets
+- Shows dataset/row counts below the dropdown
+
+---
+
+## 6. Network Map — Hunt-Scoped Interactive Map (previous session, deployed)
+
+- Hunt selector dropdown loads only that hunt's datasets
+- Enriched nodes with hostname, IP, OS metadata
+- Click-to-inspect MUI Popover showing node details
+- Zoom (wheel + buttons) and pan (drag) with full viewport transform
+- Force-directed layout with co-occurrence edges
+
+---
+
+## 7. Agent Assist — "Failed to Fetch" Diagnosis
+
+**Request:** "AI assist failed: Error: Failed to fetch"
+
+**Diagnosis:**
+- Backend agent endpoint works correctly (tested via PowerShell `Invoke-RestMethod` through nginx proxy)
+- Health endpoint healthy — both LLM nodes (Wile + Roadrunner) available
+- Extra fields sent by frontend (`mode`, `hunt_id`, `conversation_id`) are accepted by Pydantic v2 (ignored, not rejected)
+- "Failed to fetch" was a transient browser-level network error, not a backend issue
+- Response time ~5s from LLM — within nginx 120s proxy timeout
+- **Resolution:** Hard refresh (Ctrl+Shift+R) resolves the issue
+
+---
+
+## 8. Performance Fix — /api/hunts Timeout (previous session)
+
+- Root cause: `Dataset.rows` relationship had `lazy="selectin"` causing SQLAlchemy to cascade-load every DatasetRow when listing hunts
+- Fix: Changed `Dataset.rows` and `DatasetRow.annotations` to `lazy="noload"` in `backend/app/db/models.py`
+- Result: Hunts endpoint returns instantly
