# 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 8

## Current Position

Phase: 8 of 12 (DAG System TDD)
Plan: 2 of 2 in current phase
Status: Phase complete
Last activity: 2026-01-10 — Completed 08-02-PLAN.md

Progress: ██░░░░░░░░ 20%

## 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 |

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

### Deferred Issues

- CBB support (350+ D1 teams requires separate scoped phase)

### Blockers/Concerns

None.

### Roadmap Evolution

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