# Project State

## Project Reference

See: .planning/PROJECT.md (updated 2026-01-09)

**Core value:** Every game must correctly link to its teams and stadium — a game at the wrong venue or with broken team links ruins trip planning.
**Current focus:** Phase 4 — Canonical Linking

## Current Position

Phase: 4 of 7 (Canonical Linking) - COMPLETE
Plan: 1 of 1 in current phase - COMPLETE
Status: Phase 4 complete, ready for Phase 5
Last activity: 2026-01-10 — Completed 04-01 (Canonical Linking)

Progress: █████░░░░░ 58% (11 of 19 plans complete)

## Performance Metrics

**Velocity:**
- Total plans completed: 11
- Average duration: 5.8 min
- Total execution time: 64 min

**By Phase:**

| Phase | Plans | Total | Avg/Plan |
|-------|-------|-------|----------|
| 1. Script Architecture | 3/3 | 23 min | 7.7 min |
| 2. Stadium Foundation | 2/2 | 14 min | 7 min |
| 2.1. Additional Sports Stadiums | 3/3 | 17 min | 5.7 min |
| 3. Alias Systems | 2/2 | 6 min | 3 min |
| 4. Canonical Linking | 1/1 | 4 min | 4 min |

**Recent Trend:**
- Last 5 plans: 02.1-03 (6 min), 03-01 (4 min), 03-02 (2 min), 04-01 (4 min)
- Trend: Consistent, trending faster

## Accumulated Context

### Decisions

Decisions are logged in PROJECT.md Key Decisions table.
Recent decisions affecting current work:

- **01-01**: Each sport module has its own `get_{sport}_team_abbrev()` function for independence
- **01-01**: Import fallback pattern (try/except) for running from Scripts/ or project root
- **01-02**: NBA/NHL use season string format (2024-25) for cross-calendar-year seasons
- **01-02**: Each module has hardcoded stadium list with coordinates as reliable fallback
- **01-03**: NFL uses cross-calendar-year season format (2025-26) like NBA/NHL
- **01-03**: Non-core sports (WNBA, MLS, NWSL, CBB) remain inline with TODO markers
- **02-01**: Used original opening years (not renovation years) for year_opened field
- **02-01**: Stadium dataclass already supported year_opened - no changes needed to core.py
- **02-02**: MLS stadiums excluded from bundled JSON (incomplete data), deferred to Phase 2.1
- **02.1-01**: Used soccer configuration capacities for shared NFL stadiums (e.g., Mercedes-Benz 42,500 for soccer vs 71,000 for NFL)
- **02.1-01**: Prioritized hardcoded source (priority=1) over gavinr GeoJSON (priority=2) for complete data
- **02.1-02**: Cross-referenced shared arena coordinates from nba.py and nhl.py for WNBA venues
- **02.1-03**: Cross-referenced 10 of 13 NWSL stadiums from mls.py for shared venue coordinates
- **02.1-03**: CBB deferred to future phase (350+ D1 teams requires separate scoped approach)
- **04-01**: Team abbreviation aliases discovered during canonicalization runs are added iteratively to TEAM_ABBREV_ALIASES

### Roadmap Evolution

- Phase 2.1 inserted after Phase 2: Add stadium data for MLS, WNBA, NWSL, CBB (INSERTED)

### Deferred Issues
