<objective>
Audit and complete hardcoded stadium data across all 4 sport modules.

Purpose: Ensure all sport modules have complete, accurate stadium data that will flow through the canonicalization pipeline.
Output: All 4 sport modules with complete stadium data (city, state, lat/lng, capacity, year_opened, teams).

**Key files:**
@Scripts/mlb.py
@Scripts/nba.py
@Scripts/nhl.py
@Scripts/nfl.py

**Current state:**
- MLB, NBA, NHL, NFL modules have hardcoded stadium data with city, state, lat/lng, capacity, teams
- Missing field: year_opened (null in all canonical data)
- NFL module created in Phase 1 Plan 03 with 30 hardcoded stadiums
- Bundled stadiums_canonical.json has incomplete data (state="", capacity=0, missing NFL)

**Expected stadium counts:**
- MLB: 30 stadiums (30 teams)
- NBA: 30 stadiums (30 teams)
- NHL: 32 stadiums (32 teams)
- NFL: 30 stadiums (32 teams, 2 shared: SoFi Stadium, MetLife Stadium)

**Stadium data structure:**
Each module has `scrape_{sport}_stadiums_hardcoded()` returning Stadium objects with:
- name, city, state, lat/lng, capacity, teams
- Missing: year_opened for filtering historical/renamed venues

<task type="auto">
  <name>Task 1: Audit stadium data completeness across all 4 sport modules</name>
  <files>Scripts/mlb.py, Scripts/nba.py, Scripts/nhl.py, Scripts/nfl.py</files>
  <action>
1. Read each sport module's hardcoded stadium function
2. Create audit report listing for each sport:
   - Stadium count (should match expected)
   - Fields present/missing
   - Any stadiums with missing lat/lng (should be 0)
   - Any stadiums with missing capacity (should be 0)
3. Identify gaps: stadiums missing from lists, incorrect coordinates, missing teams

Do NOT modify any files in this task - audit only. The goal is to understand current state before making changes.
  </action>
  <verify>Print audit summary showing stadium counts per sport and any data quality issues found</verify>
  <done>Audit report shows MLB:30, NBA:30, NHL:32, NFL:30 stadiums with all required fields documented</done>

  <name>Task 2: Add year_opened to all hardcoded stadiums</name>
  <files>Scripts/mlb.py, Scripts/nba.py, Scripts/nhl.py, Scripts/nfl.py</files>
  <action>
Add year_opened to each stadium's hardcoded data. Use the actual opening year for each venue:

**MLB stadiums (sample):**
- Fenway Park: 1912
- Wrigley Field: 1914
- Dodger Stadium: 1962
- Globe Life Field: 2020

**NBA arenas (sample):**
- TD Garden: 1995
- Madison Square Garden: 1968
- Chase Center: 2019
- Intuit Dome: 2024

**NHL arenas:** Many share with NBA - verify and match

**NFL stadiums (sample):**
- Lambeau Field: 1957
- SoFi Stadium: 2020
- Allegiant Stadium: 2020

For each module:
1. Update the hardcoded dict to include 'year_opened' key
2. Update Stadium object creation to include year_opened parameter
3. Ensure Stadium dataclass in core.py has year_opened field (verify first)

Research actual opening years from Wikipedia if unsure. Use the original opening year, not renovation years.
  </action>
  <verify>Run `python -c "from mlb import scrape_mlb_stadiums; s=scrape_mlb_stadiums(); print(f'MLB: {len(s)} stadiums, year_opened example: {s[0].year_opened if hasattr(s[0], \"year_opened\") else \"MISSING\"}')"` for each sport</verify>
  <done>All 4 sport modules have year_opened in hardcoded data, Stadium objects include year_opened field</done>
</task>

</tasks>

Before declaring plan complete:
- [ ] Audit confirms expected stadium counts: MLB:30, NBA:30, NHL:32, NFL:30
- [ ] All 4 modules have year_opened in hardcoded stadium data
- [ ] No Python syntax errors in any module
- [ ] Stadium dataclass supports year_opened field
</verification>

<success_criteria>

- Task 1: Audit complete with documented counts and any gaps identified
- Task 2: year_opened added to all hardcoded stadiums in all 4 modules
- No import errors when loading modules
- Ready for Plan 02 (pipeline regeneration)
