Consolidate the Race Story section into a cohesive timeline surface: custom
chapter-strip scrolling with active-card sync, unified segmented playback
controls, chapter bands on the position graph with decimated axes and
de-collided labels, map toggle gated by an on-mount replay/outline probe,
and shared empty-state cards. Adds vitest coverage and visual snapshots.
Note: replay/outline queries now probe on mount (not only when Map opens) so
the toggle can be hidden before users hit a dead panel.

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.
Reframe Briefing into GP-window sections with driver/team tag chips, a sticky
"since last race" header, and client-side digest helpers (gpWindows, groupByWindow,
tagItems). Overlapping inter-race windows resolve to the latest GP; undated items
land in a Recent bucket. Vitest covers digest lib + page render/filter behaviour.

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.
Reference-null laps now emit null deltas for all drivers and exclude that
lap window from aligned cumulative totals so later comparisons stay sane.
Challenger-null behavior is unchanged. Compare tab meta documents the policy.

Add shared Meaning primitive and pure interpretation helpers for interval,
tyre age, and championship gap columns on the live tower, tyre deg panel,
and championship hub. Thresholds are exported consts (undercut window tied
to PIT_LOSS_SECONDS from #13).

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).

Replace the static weekend band with a three-state hero (live, upcoming,
between weekends) driven by heroState() and existing page queries. Between-weekend
podium uses the existing race-hub endpoint for the last ingested race session
since championship hub does not expose finish positions.

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.
Introduce a reusable SVG chart primitive for lap-by-lap cumulative time
delta vs a reference driver, with pure math in lib/delta.ts, dedicated
styles, null-lap gap handling, and Vitest coverage for math and rendering.

Extract stint timeline SVG from StrategyView into a data-source-agnostic
chart primitive with compound legend, lap-axis ticks, and hover titles.
StrategyView maps race-hub stint data into the new props contract.

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.
Fourth view on the championship page: assign P1-P10 per remaining
round and see projected standings update live, with position deltas
and mathematically alive/eliminated title states. Pure projection
logic in lib/simulator.ts (2025 points system, standard GPs only);
scenarios persist to localStorage per season. 169 frontend tests
passing.

- Track status flag banner (green/yellow/SC/VSC/red, defensive mapping)
- Weather strip: air/track temp, humidity, wind with compass, rain badge
- Gap trend sparklines from a per-driver interval ring buffer
- Battle detection: consecutive cars within 1.0s chained and highlighted
- Stint history column with compound sequence per driver
- Pinnable drivers (max 3) with focus cards, persisted to localStorage
Pure logic lives in lib/gapHistory.ts and lib/battles.ts with unit
tests; 137 frontend tests passing.

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.
