======================================================================== TECHNICAL REQUIREMENTS SPECIFICATION & MILESTONE AGREEMENT ======================================================================== Project Name: Phase 1 Sports Data Extraction & Backfill Total Budget: $100 USD (Includes 1-Month Free Technical Maintenance Warranty) 1. SYSTEM ARCHITECTURE: DUAL-SCRIPT MODULAR DESIGN To optimize system stability, simplify debugging, and facilitate modular maintenance, the software must be developed as TWO completely independent executable scripts: - Script A ([login to view URL]): Daily Match Opening Odds Ingestion Module. - Script B ([login to view URL]): 5-Year Historical Whitelist Database Backfill Module. 2. GLOBAL LEAGUE WHITELIST FILTER CONFIGURATION Both scripts must enforce the following league whitelist. The crawler MUST check the league name first. Only matches belonging to these precise leagues shall be processed; all unspecified or minor leagues must be skipped entirely: TARGET_LEAGUES = [ # ── EUROPE ── '英超', '西甲', '意甲', '德甲', '法甲', # Big 5 '荷甲', '葡超', '土超', '比甲', '苏超', # Mainstream Europe '瑞典超', '挪超', '丹超', '瑞士超', '奥甲', '希超', '捷甲', '波兰甲', '克甲', '俄超', '欧冠', '欧联杯', '欧协联', # UEFA Tournaments # ── AMERICA ── '美职联', '墨超', # North America '巴甲', '阿甲', '哥伦甲', '智利甲', '厄甲', '秘鲁甲', '巴拉甲', '乌拉甲', # South America '解放者杯', '南美杯', '美职联杯', '美金杯', # Cups # ── ASIA & OCEANIA ── '日职联', '日职乙', '天皇杯', '日联杯', # Japan Core '韩职联', '韩足总', # Korea Core '中超', '澳超', '沙特联', '卡塔尔联', '阿联酋超', # Other Asia '亚冠', '亚洲杯' # Asia Tournaments ] 3. DETAILED EXECUTION LOGIC & DATA SCHEMA 3.1 Script A: Daily Match Scraping - Target: Scan the daily fixtures/live matches list page for the current local date. - Frequency: This data represents static opening lines. Scrape ONCE per match when the market opens (or via a few timed intervals per day). No high-frequency real-time updates or WebSocket reversing required. - Tab Switching: Must switch and extract data from both [全场 (Full-Time)] and [半场 (Half-Time)] tabs. - Target Columns: Structurally extract the 3 "Opening" columns (Asian Handicap, 1X2 Match Odds, Over/Under Total Goals) for ALL 9 major bookmakers (Crown, Bet365, Ladbrokes, William Hill, Macauslot, Easybet, Victor Chandler, Mansion88, Interwetten). - Storage: Automatically export into a structured text/CSV file on the local machine, saved using the current date as the filename (e.g., [login to view URL]). 3.2 Script B: 5-Year Historical Backfill - Time Depth: Comprehensive backfill spanning the past 5 full seasons (specifically from the 2021/2022 season up to the current 2025/2026 season). - Execution Path: Loop through Season ➔ Round ➔ Match Result Page ➔ Extract 9-Bookmaker Full/Half Time Opening Lines. - Target Fields: Historical Final Scores (both Full-Time & Half-Time) must be perfectly mapped to their respective 9-bookmaker opening odds matrices. - Storage Path: All historical datasets must be structured and saved automatically directly to my local computer's D: Drive (e.g., D:\SportsData_History\). 4. CORE FAIL-SAFE & SAFETY MECHANISMS - Resume from Breakpoint (Checkpoint): The historical script MUST implement a local state-saving mechanism (e.g., [login to view URL]) written to the D: Drive. If interrupted by network drops, manual termination, or PC reboots, re-running the script must seamlessly resume from the last saved state without duplication or starting from scratch. - Polite Scraping Delay: Enforce a random sleep delay of `[login to view URL]([login to view URL](1.0, 3.0))` between match page requests to guarantee a 100% stable, ban-free operation on local residential IPs. 5. MILESTONE PLATFORM DISTRIBUTION & ACCEPTANCE CRITERIA MILESTONE 1: Initial Local Setup & Verification ($40 USD) - Deliverables: Transfer complete Python source code with clear comments (no encrypted wrappers or compiled .exe files) and a step-by-step local runtime configuration guide. - Criteria: The script successfully boots on my PC and correctly writes the first structured test batch into my D: Drive path. MILESTONE 2: 24-Hour Stability & Integrity Test ($60 USD) - Criteria: 1. The scraper runs continuously for 24 hours on my machine without any script crashes, memory leaks, or local IP bans. 2. The breakpoint resume system passes manual interruption testing (intentionally disconnecting the network/killing the process and verifying seamless recovery). 3. Full-volume 5-year historical data for whitelisted leagues is completely populated into the D: Drive. 1-MONTH FREE MAINTENANCE WARRANTY - Requirement: Provide 1 month of free technical support from the final payout date. If the target site updates its layout or selectors causing script failures during this month, patches must be applied within 24 hours for free.

Hi, I am Everett, an experienced Python developer specializing in data extraction and automation. I understand your project requires two independent scripts: one to scrape daily match odds from major bookmakers and another to backfill 5 years of historical sports data for specified leagues. The best approach is modular scripts enforcing your league whitelist, extracting relevant odds and scores, then saving structured files locally. Technically, I will use Python with libraries like requests and BeautifulSoup for scraping, pandas for CSV handling, and implement checkpointing with JSON files for fault tolerance. Randomized sleep delays will ensure ban-free operation and the resume logic supports recovery after interruptions. I can communicate in real time in your time zone and provide a working demo within 12 hours of starting. Q1: Do you have preferred Python version or environment constraints? Q2: Can you share example URLs or login details if needed? Q3: Are there specific error logging or alerting requirements? What is your preferred way to handle any new leagues to include in the whitelist in the future? Best regards, Everett

Hi, I went through your requirements carefully, and everything is very clear and well-structured. I can build this exactly the way you’ve described. I’ll develop the system as two separate scripts: • One for daily match scraping (handling full-time and half-time data, saving clean files by date) • One for the 5-year historical backfill with a reliable resume system I’ll make sure only your listed leagues are processed—no extra or unwanted data—and that all 9 bookmakers and required odds are captured correctly. The historical script will include a proper checkpoint system, so if anything stops (network, PC restart, etc.), it can continue from where it left off without duplicating data. I’ll also include safe delays between requests to keep everything stable and avoid any bans. You’ll get: • Clean, well-commented Python code (no compiled files) • Simple step-by-step setup instructions • Structured output saved directly to your D: drive as requested For testing, I’ll ensure it runs smoothly on your machine, handles interruptions properly, and completes the full historical dataset. I’m also fine with the 1-month support period and can quickly fix anything if the target site changes. If you want something reliable and built to run long-term without issues, I’m ready to start.
