# Project State

## Project Reference

See: .planning/PROJECT.md (updated 2026-01-10)

**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:** v1.1 TDD & Correctness — Phase 9

## Current Position

Phase: 9 of 12 (Trip Planner Modes TDD)
Plan: 2 of 3 in current phase
Status: In progress, executing plans
Last activity: 2026-01-10 — Completed 09-02: Scenario B filler conflict TDD

Progress: ███░░░░░░░ 30%

## Shipped Milestones

| Milestone | Phases | Plans | Shipped |
|-----------|--------|-------|---------|
| v1.0 Data Pipeline | 1-7 (+2.1) | 15 | 2026-01-10 |

## Accumulated Context

### Decisions

| Phase | Decision | Rationale |
|-------|----------|-----------|
| 08-02 | Dynamic beam width scaling (800+→50, 2K+→30, 5K+→25) | Prevents exponential blowup with large datasets while preserving diversity; achieves 10-17x speedup |
| 08-02 | Early termination (<5K at 2x, ≥5K at 3x beam width) | Stops expansion when sufficient diverse routes found; ensures consistent performance |
| 09-01 | Dynamic time buffers (same-day: 2hr/0.5hr, multi-day: 3hr/1hr) | Enables realistic doubleheaders while preserving multi-day behavior; people leave during/after first game for same-day transitions |

See also: PROJECT.md Key Decisions table for architectural decisions.

### Deferred Issues

- CBB support (350+ D1 teams requires separate scoped phase)
- Test suite flakiness: 5 tests fail in full suite but pass individually (Swift Testing parallel execution + simulator state pollution, pre-existing issue)

### Blockers/Concerns

None.

### Roadmap Evolution

- Milestone v1.1 TDD & Correctness created: Test-driven validation of trip planning engine, 5 phases (Phase 8-12)
