+# Akamai Bot Detection - Troubleshooting Todos
+
+## Problem
+First HTTP request to NSE is getting blocked/delayed by Akamai bot detection. Not detection from repeated calls, but from initial request headers/TLS mismatch.
+
+## Root Causes
+1. **Outdated User-Agent** (Chrome 80 from Feb 2020)
+2. **Missing modern browser headers** (Sec-CH-UA-*)
+3. **TLS fingerprint mismatch** (Python requests library vs claimed Chrome)
+4. **Dead/suspicious headers** (old sec-fetch values)
+
+---
+
+## Todos (Easiest to Hardest)
+
+### 1. Update User-Agent to Current Chrome
+- [x] Update Chrome version to 2026 current (Chrome 134.0.6998.166)
+- [x] Standardize all User-Agent strings across history.py, archives.py, live.py, bse/live.py
+- [ ] Test: Run test_cookie and check if Akamai accepts it
+- **Why this first**: Simplest change, highest ROI. Just string replacement.
+- **Files updated**: All 7 locations updated to Chrome 134 from Chrome 80/84/120
+
+### 2. Add Missing Sec-CH-UA Headers
+- [x] Add `Sec-CH-UA: "Google Chrome";v="134", "Chromium";v="134", "Not?A_Brand";v="99"` to match updated User-Agent
+- [x] Add `Sec-CH-UA-Mobile: ?0`
+- [x] Add `Sec-CH-UA-Platform: "Windows"`
+- [x] Add modern headers: `DNT: 1`, `Upgrade-Insecure-Requests: 1`
+- [ ] Test: Run test_cookie again
+- **Why**: Modern Akamai expects these. Real browsers always send them.
+- **Files updated**: All modules (history.py, live.py, archives.py, bse/live.py)
+
+### 3. Clean Up Suspicious Headers
+- [ ] Remove or verify `pragma: no-cache` (uncommon in modern browsers)
+- [ ] Remove or fix `Cache-Control` (should be "no-cache" or modern values)
+- [ ] Verify Referer path is realistic for the request
+- [ ] Test: Run test_cookie
+- **Why**: Outdated header combinations scream "bot"
+
+### 4. Add Common Modern Headers
+- [ ] Add `DNT: 1`
+- [ ] Add `Upgrade-Insecure-Requests: 1`
+- [ ] Adjust Accept-Language to current standards
+- [ ] Test: Run test_cookie
+
+### 5. Use `httpx` with Custom Adapter (TLS Fingerprinting)
+- [ ] Install `httpx` + `httpcore`
+- [ ] Create custom adapter with Chrome-like TLS cipher suite
+- [ ] Replace requests.Session with httpx.Client
+- **Why**: Last resort. Fixes TLS mismatch but requires redesign.
+- **Effort**: High
+
+---
+
+## Testing Strategy
+After each todo, run:
+```bash
+pytest tests/test_nse.py::test_cookie -v -s
+```
+
+Track response status codes:
+- 200 = Success
+- 403/401 = Akamai rejected us
+- Hanging/timeout = Still being throttled
