Address the independent review blockers on PR #80 after rebasing onto the
authoritative #72 Weekend Context API.
- Replace the invented frontend WeekendContext with the exact backend contract
(temporal_state, previous/focus/next meetings, previous_completed/active/next/
default_analysis sessions with availability). Every valid canonical payload now
maps to a designed state via a total resolveViewState; a well-formed response
can never fall through to the limited-data placeholder.
- Make the canonical read the single source of truth: useWeekendContext no longer
fans out to season/meetings/per-weekend/OpenF1/live queries. Only supplementary
championship + news reads run, and only once the canonical context resolves.
- Fix the Prepare/analysis flow: /preview is a stable alias that renders the
preparation surface (PreSessionView) instead of redirecting back to the same
between-races screen.
- One primary navigation system per breakpoint: the mobile top-bar links are
hidden so the bottom bar is the sole primary nav, and Admin is moved out of
every Primary landmark into an operator-utilities toolbar.
- Add Vitest coverage for the contract mapping, every temporal state, loading/
error/limited surfaces, the no-fanout guarantee, the /preview CTA, and the nav
hierarchy; add hermetic Playwright journeys (seeded + injected canonical
payloads), 390/768/1440 overflow checks, and Weekend visual snapshots. Retire
the stale Command Center specs/snapshots.

Generate deterministic template headlines server-side for each replay chapter
kind, expose Chapter.headline in the race-hub payload, and render a horizontal
chapter strip on the story view with active-chapter highlighting, click-to-jump,
and a 90-second tour mode built on the existing scrubber playback.

Spike: replay location fan-out is bounded with a semaphore at 4 concurrent GetLocation calls, covered by TestAssembleReplayFramesBoundsLocationFanOut.
Adds /api/v1/replay/frames with 5s interval floor, 3000-frame cap, nearest-sample snapping, and empty-driver omission. Wires RaceStoryCanvas to lazy-load replay frames plus cached track outlines when the map panel opens, sharing the existing scrubber/playback state across chart and map.
Tests: HOME=/private/tmp/box-box-home GOCACHE=/private/tmp/box-box-go-cache GOMODCACHE=/Users/aman/go/pkg/mod go test ./internal/web; go build ./... (same env, passed with read-only module stat-cache warning); npm run test; npx tsc --noEmit. Full go test ./... is blocked in this sandbox by existing network/listener-dependent internal/api and internal/news tests.
Add deterministic server-side chapter detection for starts, flag periods, pit phases, decisive top-five swings, and finishes, then expose chapters on the race-hub payload.
Spike result: race-hub already loads race control, positions, and laps in one read model. The requested Detect signature does not include pit stops, so pit phases use IsPitOutLap clusters as the local deterministic pit-stop proxy.
Parse and expose SessionStatus from the official live feed, treating Started/Resumed as active and terminal or missing statuses as inactive archive candidates.
Keep /api/v1/live/state and SSE snapshot data reserved for active sessions while exposing memory-only last_snapshot, last_positions, and last_snapshot_at for the explicit Live tab archive view.
Ship driver comparison in the race hub: two pickers (default top finishers),
best-lap telemetry overlays via TelemetryTraceChart, and cumulative pace
delta via DeltaTimeGraph with pit-lap captions. Car data is filtered to each
driver's fastest lap client-side (OpenF1 returns full-session samples).

Subscribe to TeamRadio on the F1 live feed, parse defensive capture snapshots and patches, and relay capped captures through live snapshots with the SessionInfo static path. Add the frontend CDN URL helper and ticker using one shared audio element.
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.
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.
