* Fix event loop blocking in NLTK downloads and Azure model listing
Found via watchdog detecting 61.6s hang during file upload.
**Root causes:**
1. NLTK punkt_tab downloads blocking during file processing
2. Azure model listing using sync requests.get() in async context
**Fixes:**
1. Pre-download NLTK data at Docker build time
2. Async fallback download at startup if build failed
3. Move Azure model fetch to thread pool with asyncio.to_thread()
**Impact:**
- Eliminates 60+ second event loop hangs
- Startup: instant if data baked in, ~60s async if needs download
- Requests: never block, all I/O offloaded to threads
* Fix Docker build: ensure /root/nltk_data exists even if download fails
- Create directory before download attempt
- Add verification step to confirm download success
- Directory always exists so COPY won't fail in runtime stage
* Fix: use venv python for NLTK download in Docker build
The builder stage installs NLTK in /app/.venv but we were using
system python which doesn't have NLTK. Now using venv python so
download actually works.
* Use uv run for NLTK download (more idiomatic)
uv run automatically uses the synced venv, cleaner than hardcoding
the venv path.
* Add lightweight event loop watchdog monitoring
- Thread-based watchdog detects event loop hangs >15s
- Runs independently, won't interfere with normal operation
- Disabled in test environments
- Minimal overhead, just heartbeat checks every 5s
* actually test it
* Add test script to validate watchdog detects hangs
Run with: uv run python test_watchdog_hang.py
Tests:
- Normal operation (no false positives)
- Short blocks under threshold (no alerts)
- Long blocks over threshold (correctly alerts)
* add memory tracking to core
* move to asyncio from threading.Thread
* remove threading.thread all the way
* delay decorator monitoring initialization until after event loop is registered
* context manager to decorator
* add psutil
* add limit of 1000 and change FE
* add safety
* const name
* update limit
* add max limit
