Subscribe to SignalR Position.z and CarData.z, decode DEFLATE payloads, stream throttled positions over SSE, and render live car dots against cached track outline bounds with tap telemetry.
Alignment spike: no checked-in or locally cached real Position.z samples were available in this isolated worktree; verified both streams expose the official raw F1 X/Y/Z coordinate contract and implemented shared-bounds normalization against prefetched OpenF1 outlines. Fallback build-outline-from-stream was not taken.
Playwright remains out of scope for live rendering because BOXBOX_DISABLE_LIVE is used there; coverage is via parser, web handler/SSE, pure transform, and seeded component tests.
Concurrent fan-outs could burst past the free-tier rate limit; callers
swallowed the 429s as missing data, and the championship hub cached the
resulting partial season for its full TTL (observed live: 8 of 22
rounds, zero wins/podiums/form).
- requestPacer spaces live requests (350ms anonymous, 100ms with key);
cache hits never wait
- get() retries 429s up to 3 times honouring Retry-After (capped 10s)
- hub tracks per-meeting fetch failures and caches incomplete
aggregates for only 2 minutes instead of 15min/24h
Verified against the live API: 2026 hub now reports all 22 rounds with
wins/podiums/form populated.

Cold-cache hub loads previously issued ~70 sequential OpenF1 calls.
Per-meeting fetches now fan out 5-wide (order preserved), and the
aggregated response is cached in memory: 15min TTL for the current
season, 24h for past seasons.

New /api/v1/championship/hub endpoint aggregates official standings with
wins, podiums, poles, recent form, teammate head-to-head, and per-round
cumulative points. ChampionshipPage renders drivers, constructors, and
progression views.
