Make bare /race-hub resolve to a completed session and never open empty
post-session analysis for a future race.
- Backend: add `default_analysis_session` to the Weekend context. It never
resolves to a future session (picks the richest completed session, ties
toward the later one; 0 when everything is upcoming). Existing
`default_session_key` and deep links are unchanged.
- Frontend default resolution prefers the most recently completed weekend
(`pickAnalysisFocusMeeting`) and consumes `default_analysis_session`, falling
back to the switcher when only upcoming sessions exist.
- New `sessionState` lib maps timing + coverage to user language
(upcoming/live/preparing/partial/ready/cancelled); the session rail, active
sub-bar, and WeekendSwitcher now label states instead of raw x/11 counts.
- Future sessions render a purpose-built PreSessionView (expected availability +
countdown) instead of empty Winner/Podium/Pole/Strategy/Compare cards.
- Analysis navigation regrouped into Story / Analysis / Data & Context; every
existing tab is preserved. Diagnostics (renamed from Data Status) is now a
secondary action and the raw dataset strip is hidden behind an explicit
toggle, so operational coverage no longer precedes fan content.
- Loading/error states offer Retry and a path back to Weekend.
Tests: Go query tests for future-exclusion; Vitest for default selection,
future pre-session, partial state, error/retry, grouped nav, and sessionState;
hermetic Playwright for bare/completed/future/return-to-Weekend; new
race-hub-future visual snapshots. Seed adds a far-future session inside the
Monaco meeting (kept in-meeting so Command Center focus is unaffected).
Note: `default_analysis_session` is an additive field on the existing
`/weekend` contract (no new endpoint), per the spec's "context contract" scope.

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.

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.
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.
