## Project-Level Changes

Changes that affect the entire project structure:

## [Unreleased]

---

## [2026.05.14]

### Packages
- **Frontend:** v0.4.4
- **Backend:** v0.3.10
- **MCP:** v0.3.4

### Changes
### Release Summary

Phase 1 complete: Line Movement Tracking feature shipped with full detection pipeline, analytics UI, and 10 follow-on bug fixes identified during post-implementation review. All filters (steam, gradual, normal), value-opportunity pages, and analytics widgets now operate correctly under default deployment settings.

### Added
- **Line Movement Analytics** (Phase 1): End-to-end feature for detecting steam moves, gradual drift, and bookmaker disagreement — backend service + scheduled job + REST API + full React UI at `/analytics/movements`

### Fixed
- Detection pipeline: steam classification from split markets, threshold misaligned with 10-min sync cadence, gradual moves never reaching `> 3600 s` threshold, duplicate rows from overlapping windows, live-game status filter, historical backlog re-processing
- Bookmaker disagreement: stale/duplicate rows in live list, h2h away-price divergence ignored, `bestValue` always reporting home/over side, commenced-but-unupdated game status gap
- Analytics UI: `SteamMoveAlert` clobbering page filter, `DisagreementBreakdown` omitting below-threshold markets, `MovementPerformance` timeframe desync, type errors, filter passthrough bug, team navigation 404s

### Component Versions
- Dashboard Backend: v0.3.6
- Dashboard Frontend: v0.4.2
- Dashboard Root: v0.2.5

See [dashboard/CHANGELOG.md](dashboard/CHANGELOG.md) for full details.

- MCP Server: v0.2.1
- Dashboard Backend: v0.2.4
