MVP Completion Checklist

Status

The local-first Web UI MVP is now functionally assembled. The app can ingest OpenF1 data into the SQLite domain store, serve local-first Race Hub and navigation APIs, render the React Race Hub/Data Library/Live Timing routes, and serve the built React app from Go web mode when frontend/dist is present.

This document replaces the temporary agent handoff prompts as the main checkpoint for what has been completed and what remains.

Completed

Live SignalR code extracted into internal/live and reused by TUI and Web mode.
SQLite domain store added for local historical data.
Session, meeting, and weekend ingestion paths added with dry-run support.
Optional analytics ingestion failures are partial, not hard blockers.
Local-first Race Hub API added with dataset availability metadata.
Local-first season, meeting, and weekend navigation APIs added.
React + TypeScript frontend added with TanStack Query and Router.
Race Hub route added for classification, grid, strategy, positions, laps, race control, weather, and dataset status.
Data Library route added for local season/weekend coverage and CLI guidance.
Live Timing route added for current backend live snapshot/SSE state.
Go web mode serves the built React app from frontend/dist and falls back to embedded legacy assets when no build is present.

Verification Commands

Run these before cutting an MVP tag or handing the repo to another agent:

go test ./internal/live ./internal/models ./internal/store ./internal/ingest ./internal/query ./internal/web
npm --prefix frontend test -- --run
npm --prefix frontend run build
npm run test:e2e
npm run test:e2e:prod
npm run test:visual
npm run test:visual:prod

Dev proxy smoke (Vite + Go API)

For a local manual smoke test with the Vite dev server proxying API calls:

go run ./scripts/seed-e2e-db/main.go --db /tmp/boxbox-mvp.db
BOXBOX_DISABLE_LIVE=1 go run ./cmd/main.go --web --db /tmp/boxbox-mvp.db --port 18080
BOXBOX_API_PORT=18080 npm run dev --prefix frontend -- --host 127.0.0.1 --port 15173 --strictPort

Then open:

http://127.0.0.1:15173/race-hub?session_key=9472
http://127.0.0.1:15173/data-library
http://127.0.0.1:15173/live

Production web smoke (Go serves built React)

Verify the same routes when Go serves frontend/dist directly (no Vite):

npm --prefix frontend run build
go run ./scripts/seed-e2e-db/main.go --db /tmp/boxbox-mvp.db
BOXBOX_DISABLE_LIVE=1 go run ./cmd/main.go --web --db /tmp/boxbox-mvp.db --port 18080

Then open:

http://127.0.0.1:18080/race-hub?session_key=9472
http://127.0.0.1:18080/data-library
http://127.0.0.1:18080/live

Automated production-serving coverage:

npm run test:e2e:prod

This runs playwright.prod.config.ts, which builds the frontend, seeds .playwright/boxbox-prod-e2e.db, starts Go web mode on port 18080, and exercises Race Hub, Data Library, Live empty state, and nav links against the built SPA.

Visual regression (Playwright screenshots)

Screenshot baselines for Race Hub, Data Library, and Live (disabled-live empty state) at desktop, tablet, and mobile viewports:

npm run test:visual
npm run test:visual:prod

Refresh baselines after intentional UI changes:

npm run test:visual:update
npm run test:visual:prod:update

Snapshots are stored under tests/visual/__snapshots__/. See 22 Phase 14 Visual Regression.

Remaining Post-MVP Work

Improve high-density mobile/iPad behavior for Live Timing and Race Hub tables.
Add persisted live-event capture and reconciliation only after defining the live storage model.
Add track outline ingestion/read models to the React app if the local data source is reliable enough.
Expand from weekend/session ingestion toward safe full-season backfill.
Add Command Center, Drivers, Standings, and Settings as separate product phases.
Revisit static archive feasibility after source mapping is proven.

Notes

--ingest-year currently discovers season meetings and sessions. Use --ingest-meeting <meeting_key> for full weekend ingestion.
The React app should continue avoiding direct OpenF1 reads. New Web UI routes should call local-first Go APIs.
The TUI live mode remains intentionally preserved. Historical Web UI parity with the TUI is not required for this MVP.
