## The Challenge

During semester examination result announcements, university portal servers experience extreme traffic surges, resulting in frequent 504 gateway timeouts and forcing thousands of students to manually refresh slow-loading web pages for days.

### 1. Robust HTML Parser with Exponential Backoff

Constructed a resilient Python scraping worker using `requests` and `BeautifulSoup4` configured with automatic retry policies and exponential backoff, preventing socket exhaustion during high-concurrency server outages.

### 2. State Diffing & Hash Verification

Implements a local state cache that hashes table structures (`hashlib.sha256`) to detect genuine grade release changes without triggering false-positive alerts on minor DOM or whitespace updates.

### 3. Immediate Telegram Notification Dispatch

When a new examination list is published, the worker immediately dispatches a formatted notification message with direct download links via the **Telegram Bot API**, delivering alerts within 30 seconds of university publication.
