+# SportsTime Data Audit Report
+
+**Generated:** 2026-01-20
+**Scope:** NBA, MLB, NFL, NHL, MLS, WNBA, NWSL
+**Data Pipeline:** Scripts → CloudKit → iOS App
+
+---
+
+## Executive Summary
+
+The data audit identified **15 issues** across the SportsTime data pipeline, with significant gaps in source reliability, stadium resolution, and iOS data freshness.
+
+| Severity | Count | Description |
+|----------|-------|-------------|
+| **Critical** | 1 | iOS bundled data severely outdated |
+| **High** | 4 | Single-source sports, NHL stadium data, NBA naming rights |
+| **Medium** | 6 | Alias gaps, outdated config, silent game exclusion |
+| **Low** | 4 | Minor configuration and coverage issues |
+
+### Key Findings
+
+**Data Pipeline Health:**
+- ✅ **Canonical ID system**: 100% format compliance across 7,186 IDs
+- ✅ **Team mappings**: All 183 teams correctly mapped with current abbreviations
+- ✅ **Referential integrity**: Zero orphan references (0 games pointing to non-existent teams/stadiums)
+- ⚠️ **Stadium resolution**: 1,466 games (21.6%) have unresolved stadiums
+
+**Critical Risks:**
+1. **ESPN single-point-of-failure** for WNBA, NWSL, MLS - if ESPN changes, 3 sports lose all data
+2. **NHL has 100% missing stadiums** - Hockey Reference provides no venue data
+3. **iOS bundled data 27% behind** - 1,820 games missing from first-launch experience
+
+**Root Causes:**
+- Stadium naming rights changed faster than alias updates (2024-2025)
+- Fallback source limit (`max_sources_to_try = 2`) prevents third source from being tried
+- Hockey Reference source limitation (no venue info) combined with fallback limit
+- iOS bundled JSON not updated with latest pipeline output
+
+---

+| Arrowhead Stadium | `stadium_nfl_geha_field_at_arrowhead_stadium` | `stadium_nfl_arrowhead_stadium` |
+
+### Historical Changes Coverage
+
+| Historical Name | Current Team | In Aliases? |
+|-----------------|--------------|-------------|
+| Montreal Expos | Washington Nationals | ✅ |
+| Seattle SuperSonics | Oklahoma City Thunder | ✅ |
+| Arizona Coyotes | Utah Hockey Club | ✅ |
+| Cleveland Indians | Cleveland Guardians | ✅ |
+| Hartford Whalers | Carolina Hurricanes | ✅ |

+| Vancouver Grizzlies | Memphis Grizzlies | ✅ |
+| Washington Redskins | Washington Commanders | ❌ Missing |
+| Washington Football Team | Washington Commanders | ❌ Missing |
+| Brooklyn Dodgers | Los Angeles Dodgers | ❌ Missing |
+
+### Issues Found
+
+| # | Issue | Severity | Description |
+|---|-------|----------|-------------|
+| 2 | Orphan stadium alias references | Medium | 5 stadium aliases point to non-existent canonical IDs (`stadium_nfl_empower_field_at_mile_high`, `stadium_nfl_geha_field_at_arrowhead_stadium`). Causes resolution failures for historical Denver/KC stadium names. |
+| 3 | No NFL team aliases | Low | Missing Washington Redskins/Football Team historical names. Limits historical game matching for NFL. |
+
+### Phase 2 Summary
+
+**Result: PASS with issues** - Alias files cover most historical changes but have referential integrity bugs.
+
+- ✅ Team aliases cover MLB/NBA/NHL historical changes
+- ✅ Stadium aliases cover naming rights changes across all sports
+- ✅ No date range validation errors
+- ❌ 5 orphan stadium references need fixing
+- ⚠️ No NFL team aliases (Washington Redskins/Football Team missing)
+
+---
+
+## Phase 3 Results: Scraper Source Reliability
+
+**Files Audited:**
+- `sportstime_parser/scrapers/base.py` (fallback logic)
+- `sportstime_parser/scrapers/nba.py`, `mlb.py`, `nfl.py`, `nhl.py`, `mls.py`, `wnba.py`, `nwsl.py`
+
+### Source Dependency Matrix
+
+| Sport | Primary | Status | Fallback 1 | Status | Fallback 2 | Status | Risk |
+|-------|---------|--------|------------|--------|------------|--------|------|
+| NBA | basketball_reference | ✅ | espn | ✅ | cbs | ❌ NOT IMPL | Medium |
+| MLB | mlb_api | ✅ | espn | ✅ | baseball_reference | ✅ | Low |
+| NFL | espn | ✅ | pro_football_reference | ✅ | cbs | ❌ NOT IMPL | Medium |
+| NHL | hockey_reference | ✅ | nhl_api | ✅ | espn | ✅ | Low |
+| MLS | espn | ✅ | fbref | ❌ NOT IMPL | - | - | **HIGH** |
+| WNBA | espn | ✅ | - | - | - | - | **HIGH** |
+| NWSL | espn | ✅ | - | - | - | - | **HIGH** |
+
+### Unimplemented Sources
+
+| Sport | Source | Line | Status |
+|-------|--------|------|--------|
+| NBA | cbs | `nba.py:421` | `raise NotImplementedError("CBS scraper not implemented")` |
+| NFL | cbs | `nfl.py:386` | `raise NotImplementedError("CBS scraper not implemented")` |
+| MLS | fbref | `mls.py:214` | `raise NotImplementedError("FBref scraper not implemented")` |
+
+### Fallback Logic Analysis
+
+**File:** `base.py:189`
+```python
+max_sources_to_try = 2  # Don't try all sources if first few return nothing
+```
+
+**Impact:**
+- Even if 3 sources are declared, only 2 are tried
+- If sources 1 and 2 fail, source 3 is never attempted
+- This limits resilience for NBA, MLB, NFL, NHL which have 3 sources
+
+### International Game Filtering
+
+| Sport | Hardcoded Locations | Notes |
+|-------|---------------------|-------|
+| NFL | London, Mexico City, Frankfurt, Munich, São Paulo | ✅ Complete for 2025 |
+| NHL | Prague, Stockholm, Helsinki, Tampere, Gothenburg | ✅ Complete for 2025 |
+| NBA | None | ⚠️ No international filtering (Abu Dhabi games?) |
+| MLB | None | ⚠️ No international filtering (Mexico City games?) |
+| MLS | None | N/A (domestic only) |
+| WNBA | None | N/A (domestic only) |
+| NWSL | None | N/A (domestic only) |
+
+### Single Point of Failure Risk
+
+| Sport | Primary Source | If ESPN Fails... | Risk Level |
+|-------|----------------|------------------|------------|
+| WNBA | ESPN only | **Complete data loss** | Critical |
+| NWSL | ESPN only | **Complete data loss** | Critical |
+| MLS | ESPN only (fbref not impl) | **Complete data loss** | Critical |
+| NBA | Basketball-Ref → ESPN | ESPN fallback available | Low |
+| NFL | ESPN → Pro-Football-Ref | Fallback available | Low |
+| NHL | Hockey-Ref → NHL API → ESPN | Two fallbacks | Very Low |
+| MLB | MLB API → ESPN → B-Ref | Two fallbacks | Very Low |
+
+### Issues Found
+
+| # | Issue | Severity | Description |
+|---|-------|----------|-------------|
+| 4 | WNBA/NWSL/MLS single source | High | ESPN is the only working source for 3 sports. If ESPN changes or fails, data collection completely stops. |
+| 5 | max_sources_to_try = 2 | High | Third fallback source never tried even if available. Reduces resilience for NBA/MLB/NFL/NHL. |
+| 6 | CBS/FBref not implemented | Medium | Declared fallback sources raise NotImplementedError. Appears functional in config but fails at runtime. |
+
+### Phase 3 Summary
+
+**Result: FAIL** - Critical single-point-of-failure for 3 sports.
+
+- ❌ WNBA, NWSL, MLS have only ESPN (no resilience)
+- ❌ Fallback limit of 2 prevents third source from being tried
+- ⚠️ CBS and FBref declared but not implemented
+- ✅ MLB and NHL have full fallback chains
+- ✅ International game filtering present for NFL/NHL
+

+### Coverage Summary
+
+| Sport | Scraped | Expected | Coverage | Status |
+|-------|---------|----------|----------|--------|
+| NBA   | 1,231   | 1,230    | 100.1%   | ✅ |
+| MLB   | 2,866   | 2,430    | 117.9%   | ⚠️ Includes spring training |

+| WNBA  | 2025-05-02 | 2025-10-11 | Regular season + playoffs |
+| NWSL  | 2025-03-15 | 2025-11-23 | Regular season + playoffs |
+
+### Game Status Distribution
+
+All games across all sports have status `unknown` - game status is not being properly parsed from sources.
+
+### Duplicate Game Detection
+
+| Sport | Duplicates Found | Details |
+|-------|-----------------|---------|
+| NBA   | 0 | ✅ |
+| MLB   | 1 | `game_mlb_2025_20250508_det_col_1` appears twice (doubleheader handling issue) |
+| NFL   | 0 | ✅ |
+| NHL   | 0 | ✅ |
+| MLS   | 0 | ✅ |
+| WNBA  | 0 | ✅ |
+| NWSL  | 0 | ✅ |
+
+### Validation Report Analysis
+
+| Sport | Total Games | Unresolved Teams | Unresolved Stadiums | Manual Review Items |
+|-------|-------------|------------------|---------------------|---------------------|
+| NBA   | 1,231 | 0 | **131** | 131 |
+| MLB   | 2,866 | 12 | 4 | 20 |
+| NFL   | 330 | 1 | 5 | 11 |
+| NHL   | 1,312 | 0 | 0 | **1,312** (all missing stadiums) |
+| MLS   | 542 | 1 | **64** | 129 |
+| WNBA  | 322 | 5 | **65** | 135 |
+| NWSL  | 189 | 0 | **16** | 32 |
+
+### Top Unresolved Stadium Names (Recent Naming Rights)
+
+| Stadium Name | Occurrences | Actual Venue | Issue |
+|--------------|-------------|--------------|-------|
+| Sports Illustrated Stadium | 11 | MLS expansion venue | New venue, missing alias |
+| Mortgage Matchup Center | 8 | Rocket Mortgage FieldHouse (CLE) | 2025 naming rights change |
+| ScottsMiracle-Gro Field | 4 | MLS Columbus Crew | Missing alias |
+| Energizer Park | 3 | MLS CITY SC (STL?) | Missing alias |
+| Xfinity Mobile Arena | 3 | Intuit Dome (LAC) | 2025 naming rights change |
+| Rocket Arena | 3 | Toyota Center (HOU) | Potential name change |
+| CareFirst Arena | 2 | Washington Mystics venue | New WNBA venue name |
+
+### Unresolved Teams (Exhibition/International)
+
+| Team Name | Sport | Type | Games |
+|-----------|-------|------|-------|
+| BRAZIL | WNBA | International exhibition | 2 |
+| Toyota Antelopes | WNBA | Japanese team | 2 |
+| TEAM CLARK | WNBA | All-Star Game | 1 |
+| (Various MLB) | MLB | International teams | 12 |
+| (MLS international) | MLS | CCL/exhibition | 1 |
+| (NFL preseason) | NFL | Pre-season exhibition | 1 |
+
+### NHL Stadium Data Issue
+
+**Critical:** Hockey Reference does not provide stadium data. All 1,312 NHL games have `raw_stadium: None`, causing 100% of games to have missing stadium IDs. The NHL fallback sources (NHL API, ESPN) should provide this data, but the `max_sources_to_try = 2` limit combined with Hockey Reference success means fallbacks are never attempted.
+
+### Expected Count Updates Needed
+
+| Sport | Current Expected | Recommended | Reason |
+|-------|------------------|-------------|--------|
+| WNBA | 220 | **286** | 13 teams × 44 games / 2 (expanded with Golden State Valkyries) |
+| NFL | 272 | 272 (filter preseason) | Or document that 330 includes preseason |
+| MLB | 2,430 | 2,430 (filter spring training) | Or document that 2,866 includes spring training |
+
+### Issues Found
+
+| # | Issue | Severity | Description |
+|---|-------|----------|-------------|
+| 7 | NHL has no stadium data | High | Hockey Reference provides no venue info. All 1,312 games missing stadium_id. Fallback sources not tried. |
+| 8 | 131 NBA stadium resolution failures | High | Recent naming rights changes ("Mortgage Matchup Center", "Xfinity Mobile Arena") not in aliases. |
+| 9 | Outdated WNBA expected count | Medium | Config says 220 but WNBA expanded to 13 teams in 2025; actual is 322 (286 regular + playoffs). |
+| 10 | MLS/WNBA stadium alias gaps | Medium | 64 MLS + 65 WNBA unresolved stadiums from new/renamed venues. |
+| 11 | Game status not parsed | Low | All games have status `unknown` instead of final/scheduled/postponed. |
+
+### Phase 4 Summary
+
+**Result: FAIL** - Significant stadium resolution failures across multiple sports.
+
+- ❌ 131 NBA games missing stadium (naming rights changes)
+- ❌ 1,312 NHL games missing stadium (source doesn't provide data)
+- ❌ 64 MLS + 65 WNBA stadiums unresolved (new/renamed venues)
+- ⚠️ WNBA expected count severely outdated (220 vs 322 actual)
+- ⚠️ MLB/NFL include preseason/spring training games
+- ✅ No significant duplicate games (1 MLB doubleheader edge case)
+- ✅ All teams resolved except exhibition/international games
+
+---
+
+## Phase 5 Results: Canonical ID Consistency
+
+**Files Audited:**
+- `sportstime_parser/normalizers/canonical_id.py` (Python ID generation)
+- `SportsTime/Core/Models/Local/CanonicalModels.swift` (iOS models)
+- `SportsTime/Core/Services/BootstrapService.swift` (iOS JSON parsing)
+- All `Scripts/output/*.json` files (generated IDs)
+
+### Format Validation
+
+| Type | Total IDs | Valid | Invalid | Pass Rate |
+|------|-----------|-------|---------|-----------|
+| Team | 183 | 183 | 0 | 100.0% ✅ |
+| Stadium | 211 | 211 | 0 | 100.0% ✅ |
+| Game | 6,792 | 6,792 | 0 | 100.0% ✅ |
+
+### ID Format Patterns (all validated)
+
+```
+Teams:    team_{sport}_{abbrev}                  → team_nba_lal
+Stadiums: stadium_{sport}_{normalized_name}       → stadium_nba_cryptocom_arena
+Games:    game_{sport}_{season}_{YYYYMMDD}_{away}_{home}[_{#}]
+                                                  → game_nba_2025_20251021_hou_okc
+```
+
+### Normalization Quality
+
+| Check | Result |
+|-------|--------|
+| Double underscores (`__`) | 0 found ✅ |
+| Leading/trailing underscores | 0 found ✅ |
+| Uppercase letters | 0 found ✅ |
+| Special characters | 0 found ✅ |
+
+### Abbreviation Lengths (Teams)
+
+| Length | Count |
+|--------|-------|
+| 2 chars | 21 |
+| 3 chars | 161 |
+| 4 chars | 1 |
+
+### Stadium ID Lengths
+
+- Minimum: 8 characters
+- Maximum: 29 characters
+- Average: 16.2 characters
+
+### iOS Cross-Compatibility
+
+| Aspect | Status | Notes |
+|--------|--------|-------|
+| Field naming convention | ✅ Compatible | Python uses snake_case; iOS `BootstrapService` uses matching Codable structs |
+| Deterministic UUID generation | ✅ Compatible | iOS uses SHA256 hash of canonical_id - matches any valid string |
+| Schema version | ✅ Compatible | Both use version 1 |
+| Required fields | ✅ Present | All iOS-required fields present in JSON output |
+
+### Field Mapping (Python → iOS)
+
+| Python Field | iOS Field | Notes |
+|--------------|-----------|-------|
+| `canonical_id` | `canonicalId` | Mapped via `JSONCanonicalStadium.canonical_id` → `CanonicalStadium.canonicalId` |
+| `home_team_canonical_id` | `homeTeamCanonicalId` | Explicit mapping in BootstrapService |
+| `away_team_canonical_id` | `awayTeamCanonicalId` | Explicit mapping in BootstrapService |
+| `stadium_canonical_id` | `stadiumCanonicalId` | Explicit mapping in BootstrapService |
+| `game_datetime_utc` | `dateTime` | ISO 8601 parsing with fallback to legacy format |
+
+### Issues Found
+
+**No issues found.** All canonical IDs are:
+- Correctly formatted according to defined patterns
+- Properly normalized (lowercase, no special characters)
+- Deterministic (same input produces same output)
+- Compatible with iOS parsing
+
+### Phase 5 Summary
+
+**Result: PASS** - All canonical IDs are consistent and iOS-compatible.
+

+**Result:** 100% valid team → stadium references.
+
+### Cross-Sport Stadium Check
+
+✅ No stadiums are duplicated across sports. Each `stadium_{sport}_*` ID is unique to its sport.
+
+### Missing Stadium Root Causes
+
+| Sport | Missing | Root Cause |
+|-------|---------|------------|
+| NHL | 1,312 | **Hockey Reference provides no venue data** - source limitation |
+| MLS | 64 | New/renamed stadiums not in aliases (see Phase 4) |
+| WNBA | 65 | New venue names not in aliases (see Phase 4) |
+| NWSL | 16 | Expansion team venues + alternate venues |
+| NFL | 5 | International games not in stadium mappings |
+| MLB | 4 | Exhibition/international games |
+

+|----------------|---------------|---------------|
+| Game → Home Team | 6,792 | 0 ✅ |
+| Game → Away Team | 6,792 | 0 ✅ |
+| Game → Stadium | 6,792 | 0 ✅ |
+| Team → Stadium | 183 | 0 ✅ |
+
+**Note:** Zero orphan references. All "missing" stadiums are resolution failures (empty string), not references to non-existent canonical IDs.
+
+### Issues Found
+
+| # | Issue | Severity | Description |
+|---|-------|----------|-------------|
+| 12 | NHL games have no stadium data | Medium | Hockey Reference source doesn't provide venue information. All 1,312 NHL games have empty stadium_canonical_id. Fallback sources could provide this data but are limited by `max_sources_to_try = 2`. |
+
+### Phase 6 Summary
+
+**Result: PASS with known limitations** - No orphan references exist; missing stadiums are resolution failures.
+
+- ✅ 100% valid team references (home and away)
+- ✅ 100% valid team → stadium references
+- ✅ No orphan references to non-existent canonical IDs
+- ⚠️ 1,466 games (21.6%) have empty stadium_canonical_id (resolution failures, not orphans)
+- ⚠️ NHL accounts for 90% of missing stadium data (source limitation)

+**Files Audited:**
+- `SportsTime/Core/Services/BootstrapService.swift` (JSON parsing)
+- `SportsTime/Core/Services/CanonicalSyncService.swift` (CloudKit sync)
+- `SportsTime/Core/Services/DataProvider.swift` (data access)

+- `SportsTime/Resources/*_canonical.json` (bundled data files)
+
+### Bundled Data Comparison
+
+| Data Type | iOS Bundled | Scripts Output | Difference | Status |
+|-----------|-------------|----------------|------------|--------|
+| Teams     | 148         | 183            | **-35** (19%) | ❌ STALE |
+| Stadiums  | 122         | 211            | **-89** (42%) | ❌ STALE |
+| Games     | 4,972       | 6,792          | **-1,820** (27%) | ❌ STALE |
+
+**iOS bundled data is significantly outdated compared to Scripts output.**
+
+### Field Mapping Verification
+
+| Python Field | iOS JSON Struct | iOS Model | Type Match | Status |
+|--------------|-----------------|-----------|------------|--------|
+| `canonical_id` | `canonical_id` | `canonicalId` | String ✅ | ✅ |
+| `name` | `name` | `name` | String ✅ | ✅ |
+| `game_datetime_utc` | `game_datetime_utc` | `dateTime` | ISO 8601 → Date ✅ | ✅ |
+| `date` + `time` (legacy) | `date`, `time` | `dateTime` | Fallback parsing ✅ | ✅ |
+| `home_team_canonical_id` | `home_team_canonical_id` | `homeTeamCanonicalId` | String ✅ | ✅ |
+| `away_team_canonical_id` | `away_team_canonical_id` | `awayTeamCanonicalId` | String ✅ | ✅ |
+| `stadium_canonical_id` | `stadium_canonical_id` | `stadiumCanonicalId` | String ✅ | ✅ |
+| `sport` | `sport` | `sport` | String ✅ | ✅ |
+| `season` | `season` | `season` | String ✅ | ✅ |
+| `is_playoff` | `is_playoff` | `isPlayoff` | Bool ✅ | ✅ |
+| `broadcast_info` | `broadcast_info` | `broadcastInfo` | String? ✅ | ✅ |
+
+**Result:** All field mappings are correct and compatible.
+
+### Date Parsing Compatibility
+
+iOS `BootstrapService` supports both formats:
+
+```swift
+// New canonical format (preferred)
+let game_datetime_utc: String?  // ISO 8601
+
+// Legacy format (fallback)
+let date: String?   // "YYYY-MM-DD"
+let time: String?   // "HH:mm" or "TBD"
+```
+
+**Current iOS bundled games use legacy format.** After updating bundled data, new `game_datetime_utc` format will be used.
+
+### Missing Reference Handling
+
+**`DataProvider.filterRichGames()` behavior:**
+```swift
+return games.compactMap { game in
+    guard let homeTeam = teamsById[game.homeTeamId],
+          let awayTeam = teamsById[game.awayTeamId],
+          let stadium = stadiumsById[game.stadiumId] else {
+        return nil  // ⚠️ Silently drops game
+    }
+    return RichGame(...)
+}
+```
+
+**Impact:**
+- Games with missing stadium IDs are **silently excluded** from RichGame queries
+- No error logging or fallback behavior
+- User sees fewer games than expected without explanation
+
+### Deduplication Logic
+
+**Bootstrap:** No explicit deduplication. If bundled JSON contains duplicate canonical IDs, both would be inserted into SwiftData (leading to potential query issues).
+
+**CloudKit Sync:** Uses upsert pattern with canonical ID as unique key - duplicates would overwrite.
+
+### Schema Version Compatibility
+
+| Component | Schema Version | Status |
+|-----------|----------------|--------|
+| Scripts output | 1 | ✅ |
+| iOS CanonicalModels | 1 | ✅ |
+| iOS BootstrapService | Expects 1 | ✅ |
+
+**Compatible.** Schema version mismatch protection exists in `CanonicalSyncService`:
+```swift
+case .schemaVersionTooNew(let version):
+    return "Data requires app version supporting schema \(version). Please update the app."
+```
+
+### Bootstrap Order Validation
+
+iOS bootstraps in correct dependency order:
+1. Stadiums (no dependencies)
+2. Stadium aliases (depends on stadiums)
+3. League structure (no dependencies)
+4. Teams (depends on stadiums)
+5. Team aliases (depends on teams)
+6. Games (depends on teams + stadiums)
+
+**Correct - prevents orphan references during bootstrap.**
+
+### CloudKit Sync Validation
+
+`CanonicalSyncService` syncs in same dependency order and tracks:
+- Per-entity sync timestamps
+- Skipped records (incompatible schema version)
+- Skipped records (older than local)
+- Sync duration and cancellation
+
+**Well-designed sync infrastructure.**
+
+### Issues Found
+
+| # | Issue | Severity | Description |
+|---|-------|----------|-------------|
+| 13 | iOS bundled data severely outdated | **Critical** | Missing 35 teams (19%), 89 stadiums (42%), 1,820 games (27%). First-launch experience shows incomplete data until CloudKit sync completes. |
+| 14 | Silent game exclusion in RichGame queries | Medium | `filterRichGames()` silently drops games with missing team/stadium references. Users see fewer games without explanation. |
+| 15 | No bootstrap deduplication | Low | Duplicate game IDs in bundled JSON would create duplicate SwiftData records. Low risk since JSON is generated correctly. |
+
+### Phase 7 Summary
+
+**Result: FAIL** - iOS bundled data is critically outdated.
+
+- ❌ iOS bundled data missing 35 teams, 89 stadiums, 1,820 games
+- ⚠️ Games with unresolved references silently dropped from RichGame queries
+- ✅ Field mapping between Python and iOS is correct
+- ✅ Date parsing supports both legacy and new formats
+- ✅ Schema versions are compatible
+- ✅ Bootstrap/sync order handles dependencies correctly

+
+| # | Issue | Severity | Phase | Root Cause | Remediation |
+|---|-------|----------|-------|------------|-------------|

+| 11 | Game status not parsed | **Low** | 4 | Status field always "unknown" | Parse game status from source data (final, scheduled, postponed) |
+| 15 | No bootstrap deduplication | **Low** | 7 | No explicit duplicate check during bootstrap | Add deduplication check in bootstrapGames() |
+
+---
+
+## Recommended Next Steps
+
+### Immediate (Before Next Release)
+
+1. **Update iOS bundled data** (Issue #13)
+   ```bash
+   cp Scripts/output/stadiums_*.json SportsTime/Resources/stadiums_canonical.json
+   cp Scripts/output/teams_*.json SportsTime/Resources/teams_canonical.json
+   cp Scripts/output/games_*.json SportsTime/Resources/games_canonical.json
+   ```
+
+2. **Fix NHL stadium data** (Issues #7, #12)
+   - Change NHL primary source from Hockey Reference to NHL API
+   - Or: Increase `max_sources_to_try` to 3 so fallbacks are attempted
+
+3. **Add critical stadium aliases** (Issues #8, #10)
+   - "Mortgage Matchup Center" → `stadium_nba_rocket_mortgage_fieldhouse`
+   - "Xfinity Mobile Arena" → `stadium_nba_intuit_dome`
+   - Run validation report to identify all unresolved venue names
+
+### Short-term (This Quarter)
+
+4. **Implement MLS fallback source** (Issue #4)
+   - FBref has MLS data with venue information
+   - Reduces ESPN single-point-of-failure risk
+
+5. **Fix orphan alias references** (Issue #2)
+   - Correct 5 NFL stadium aliases pointing to wrong canonical IDs
+   - Add validation check to prevent future orphan references
+
+6. **Update expected game counts** (Issue #9)
+   - WNBA: 220 → 286 (13 teams × 44 games / 2)
+
+### Long-term (Next Quarter)
+
+7. **Implement WNBA/NWSL fallback sources** (Issue #4)
+   - Consider WNBA League Pass API or other sources
+   - NWSL has limited data availability - may need to accept ESPN-only
+
+8. **Add RichGame partial loading** (Issue #14)
+   - Log games dropped due to missing references
+   - Consider returning games with placeholder stadiums for NHL
+
+9. **Parse game status** (Issue #11)
+   - Extract final/scheduled/postponed from source data
+   - Enables filtering by game state
+

+
+## Verification Checklist
+
+After implementing fixes, verify:
+
+- [ ] Run `python -m sportstime_parser scrape --sport all --season 2025`
+- [ ] Check validation reports show <5% unresolved stadiums per sport
+- [ ] Copy output JSON to iOS Resources/
+- [ ] Build iOS app and verify data loads at startup
+- [ ] Query RichGames and verify game count matches expectations
+- [ ] Run CloudKit sync and verify no errors
