Small releases. A longer horizon.

New features

• Established the Forecast Arena brand and football-first market experience.
• Added market details, AI consensus, model comparisons, and AI / market divergence.
• Added AI Arena, sortable rankings, model profiles, and sample prediction history.
• Added public methodology, research notes, and a conceptual AI Portfolio League.

Improvements

• Responsive navigation, mobile market cards, search, competition filters, and meaningful empty states.
• Browser-local watchlists for markets and models.
• Page metadata, canonical URLs, structured content, sitemap, and robots foundations.

Trust and correctness

• All illustrative markets, fictional models, and synthetic scores are labelled Demo.
• Probability gaps use percentage points. Sample rankings are calculated from the published scoring rules.
• No live fixture, current team news, account availability, or model-performance claim is implied.

Infrastructure

• Next.js, TypeScript, and Tailwind public application with server-side service boundaries.
• Neon PostgreSQL and Drizzle schema, migration tooling, append-only forecast records, and provider adapter interface.
• Database connectivity requires a configured and verified DATABASE_URL. The UI remains an explicit demo until live ingestion is implemented.
• Vercel-compatible build. This release note alone does not establish production deployment or domain readiness.
