- src/live/last-seen.ts: formatLastSeen(ts, now) — "now" / "Ns ago" /
"Nm ago" / "HH:MM".
- src/live/use-staleness.ts: useStalenessTick(intervalMs=1000) hook
re-renders subscribers every interval with the current epoch ms.
- src/ui/components/connection-chip.tsx: <ConnectionChip /> bottom-left,
three states (connected / connecting+reconnecting / disconnected),
aria-live polite + role status.
- src/map/layers/map-positions.tsx: every FeatureProps now carries
staleSec; both symbol layers interpolate icon-opacity (and text-opacity
on the non-selected layer) on staleSec — 0-60s full opacity,
5min faded, 30min very faded. Update effect rebuilds features at the
staleness tick rate (1Hz).
- src/routes/_authed/monitor.tsx: renders <ConnectionChip />.
- src/live/index.ts: re-exports formatLastSeen + useStalenessTick.
Strategy A (faded marker via interpolation) chosen over Strategy B
(separate warning-badge layer) per the task's open-question
resolution; simpler and easier to extend later.
Deviations:
1. stalenessTick is its own hook in src/live/use-staleness.ts rather
than a property on the position store — keeps the store clean of
UI-driven re-render concerns; the hook is reusable.
2. <DeviceLastSeen deviceId> standalone component skipped — the SPA
doesn't have a sidebar yet (Phase 3.4); the per-marker fade IS the
indicator for v1.
Bundle: main 396KB / 121KB gz — small bump from 2.8.
🎉 Phase 2 — Live monitoring map — complete. All 9 tasks shipped.
End-to-end: login -> /monitor -> event auto-selects -> snapshot
positions render -> live updates flow via WS through the rAF
coalescer -> staleness fades stale markers -> connection chip
surfaces WS state. Dogfood-blocking work for Rally Albania 2026 done.
- src/map/core/map-pref-store.ts: mapFollow boolean (default true) +
setter. Persisted via trm-map-prefs.
- src/map/core/camera/default-camera.tsx: <MapDefaultCamera /> fits
the snapshot's bounds once per activeEventId change. Uses a
fittedFor ref; resets to null when activeEventId becomes null.
Single-point events centre+zoom 12; multi-point fitBounds with
padding capped at min(canvas*0.1, 80).
- src/map/core/camera/selected-device.tsx: <MapSelectedDevice />
pans+zooms on selection change, smooth pans on subsequent position
updates with mapFollow on. Separate effect listens for user-gesture
movestart (originalEvent truthy) and flips mapFollow off.
- src/map/core/camera/map-camera.tsx: <MapCamera coordinates> imperative
one-shot. Phase 2 doesn't use it; primitive for replay (Phase 4) and
future "fit to all" UI.
- src/map/core/follow-toggle.tsx: <FollowToggle /> icon-button using
Lucide Locate/LocateOff. Sits below the trails toggle.
- src/routes/_authed/monitor.tsx: renders FollowToggle, MapDefaultCamera,
MapSelectedDevice.
Deviations:
- Manual-pan listener uses an inline { originalEvent?: unknown } type
instead of MapLibre's MapMouseEvent|MapTouchEvent union (typing
friction across version bumps).
- MapDefaultCamera clears fittedFor on activeEventId === null so
re-selecting the same event later re-fits.
Bundle: main 395KB / 120KB gz, no measurable change.
- src/data/events.ts: useUserEvents() TanStack Query (5-min stale,
sort -starts_at). EventSummary type is a Pick of EventRow.
- src/live/active-event.ts: useActiveEventOrchestration() returns the
swap fn — unsubscribe previous + clearForEvent + subscribe new +
applySnapshot on success + persist to localStorage. Out-of-order
safety via per-call version counter. Plus readSavedActiveEventId().
- src/ui/components/event-picker.tsx: <EventPicker> dropdown.
useState + click-outside; rows show name + date + discipline.
- src/live/index.ts: re-exports active-event helpers.
- src/routes/_authed/monitor.tsx: auto-select effect (one-shot via
initializedRef, gated on events loaded + WS connected); renders
<EventPicker> wired to setActiveEvent.
Deviations:
1. Vanilla div + useState dropdown instead of shadcn Popover —
no new shadcn primitive add; easy to swap later for keyboard nav.
2. Auto-select gated on connectionStatus === 'connected' so the
subscribe call gets the snapshot path (not 'not-connected').
3. Logout-clears-saved-event-id deferred to a small Phase 1.8
follow-up; documented in task risks.
Bundle: 395KB / 120KB gz (~1KB up from 2.6).
- src/map/core/map-pref-store.ts: trailMode preference
('none' | 'selected' | 'all', default 'selected') + setter, persisted.
- src/map/layers/map-trails.tsx: <MapTrails /> side-effect-only.
Single GeoJSON source + single line layer. Builds one LineString
Feature per device whose trail has >= 2 points; filtered by mode.
Per-device flat colour via deterministic deviceId hash mod a
6-entry palette.
- src/map/core/trails-toggle.tsx: <TrailsToggle /> floating card
below <BasemapSwitcher />. Three buttons (None / Selected / All).
- src/routes/_authed/monitor.tsx: renders <TrailsToggle /> +
<MapTrails /> *before* <MapPositions /> so the line layer is added
to the map first and renders underneath the symbol layers.
Speed-coloured-per-segment deferred to Phase 3 polish per the task
spec's open-question decision; flat-colour-per-device for v1.
Bundle: main 394KB / 120KB gz — no change from 2.5.
- src/data/devices.ts: useDevicesById() — TanStack Query (5-min stale)
returning Map<deviceId, Device>. deviceLabel() formats human-readable
titles ("FMB920 #3458").
- src/map/layers/map-positions.tsx: <MapPositions /> side-effect-only.
Two GeoJSON sources (clustered non-selected + unclustered selected).
Five layers: non-selected symbol + direction + cluster-bubble,
selected symbol + direction. Click handlers: marker -> selectDevice,
cluster -> getClusterExpansionZoom + easeTo. Hover toggles cursor.
- src/routes/_authed/monitor.tsx: renders <MapPositions /> inside
<MapView>.
Schema overhaul in src/auth/client.ts:
- Made Schema SDK-compatible. Each entry is an *array* of row types
(devices: DeviceRow[], not just DeviceRow). RegularCollections<Schema>
filters on array-like values; non-arrays collapse to never which
broke readItems('devices', ...) with keyof Schema = never.
- Spelled out the composed client type as DirectusClient<Schema> &
RestClient<Schema> & AuthenticationClient<Schema> — without the
explicit annotation Schema didn't flow through .with(...) chain to
request() call sites.
- Added DeviceRow + EventRow types; exported via @/auth.
useDevicesById uses readItems<Schema, 'devices', Query<Schema, DeviceRow>>
— explicit generics because the SDK doesn't infer Schema from the
receiver's type at call sites.
Deviations:
1. Spec referenced device.kind for category — Phase 1 schema doesn't
have it yet; everything maps to 'default'. Refine when kind lands.
2. Cluster bubble uses 'default-neutral' sprite instead of a dedicated
'cluster-background' (not in 2.3's registry). Swap in 3.8.
3. getClusterExpansionZoom is Promise-based in maplibre-gl 5.x (was
callback-style); used .then().
Bundle: main bundle 394KB / 120KB gz, ~1KB up from 2.4. /monitor
chunk includes the new layer module (~10KB).
- pnpm add maplibre-google-maps (runtime; lazy-imported on Google use).
- src/map/core/styles.ts: BasemapDescriptor model with four entries
(Esri Satellite / OpenTopoMap / OSM / Google Satellite).
Google entry gated on cfg.googleMapsKey via available(cfg).
styleCustom() builds a single-raster-source MapLibre style with a
glyphs URL for future label rendering.
ensureGoogleProtocol() lazy-loads maplibre-google-maps + addProtocol
on first use; _googleRegistered guards re-registration.
- src/map/core/map-pref-store.ts: Zustand + persist middleware
(key: trm-map-prefs, version: 1). Holds basemapId + setBasemap.
- src/map/core/basemap-switcher.tsx: floating control top-right of
<MapView>. Filters by available(cfg), highlights active, applies via
getMap().setStyle(). Mount-time bootstrap (no UI state) + user-driven
onClick (with switching state) split to satisfy React 19's
react-hooks/set-state-in-effect rule.
- src/routes/_authed/monitor.tsx: renders <BasemapSwitcher /> as a
child of <MapView>.
- src/vite-env.d.ts: ambient module declaration for
maplibre-google-maps (no .d.ts ships in the package).
Deviations:
- BasemapDescriptor.style is buildStyle(cfg): StyleSpecification, not
the spec's StyleSpecification|string union. Google needs the cfg key
at build time; uniform function shape across all entries is cleaner.
- Bootstrap apply path doesn't use the switching UI state (no visual
feedback needed during the silent first-paint flip from OSM to user
preference). User-click path keeps setSwitching for the in-flight
indicator.
Bundle: MapLibre is now its own chunk (1MB / 273KB gz), shared across
maplibre consumers. Main bundle 371KB / 114KB gz.
- pnpm add maplibre-gl + -D @types/geojson.
- src/map/core/styles.ts: defaultStyle (OSM raster bootstrap; 2.2
replaces with the basemap-switcher descriptor table).
- src/map/core/map-view.tsx: module-level Map singleton lazily created
on first <MapView> mount, attached to a class="trm-map-host" detached
<div> that React refs append/remove on mount/unmount. Style-data
lifecycle flips mapReady false on every styledata event, polls
loaded() at 33ms intervals, flips ready true once the style is
loaded — the canonical MapLibre style-swap dance.
- Exports getMap()/getMapReady()/subscribeMapReady()/useMapReady (via
useSyncExternalStore for SSR-safe + concurrent-safe reads). getMap()
throws if called pre-mount; the explicit failure mode beats a
null-able top-level export.
- src/routes/_authed/monitor.tsx: new /monitor route, full-viewport
<MapView /> for 2.1 (no children — subsequent tasks plug in here).
- src/routes/_authed/index.tsx: home-page card now links to /monitor.
- eslint.config.js: override for src/map/** + src/live/** disables
react-refresh/only-export-components. Same pattern as the existing
overrides for shadcn primitives and route files.
Deviation: spec sketched a top-level `map` constant export; implemented
as `getMap(): MapLibreMap` (a function) so the singleton stays lazy
until <MapView> mounts. Top-level constant would either force eager
init (breaks SSR/tests) or be nullable (footgun). The function form
throws a clear error if called pre-mount.
Bundle: /monitor lazy chunk is 1MB raw / 274KB gzipped (MapLibre + CSS).
Other routes unaffected. Vite chunk-size warning is harmless.
Bug 1: hard-loading / while unauthenticated stayed stuck on "Loading..."
forever. Cause: the _authed layout short-circuits to the spinner when
status is anything other than 'authenticated', which means child routes
never mount. The redirect-on-anonymous useEffect lived only in the
home page (_authed/index.tsx), so it never fired — the layout's spinner
was the last thing rendered.
Fix: add a useEffect to the _authed layout component itself that
navigates to /login on the 'anonymous' transition. The layout's gate
is now: beforeLoad redirects on cold-known-anonymous, useEffect
redirects on post-mount transitions to anonymous (e.g. boot probe
resolves to anonymous after the route already rendered).
Bug 2: console warning that @tanstack/router-devtools moved to
@tanstack/react-router-devtools. Same package, renamed.
Fix: pnpm remove @tanstack/router-devtools && pnpm add -D
@tanstack/react-router-devtools; updated the lazy import in __root.tsx
to point at the new package name.
Plus: TRM_Design_System-handoff/ added to .prettierignore — those files
are immutable source material from claude.ai/design and shouldn't be
reformatted.
- src/auth/logout.ts: performLogout({ queryClient, navigate? })
orchestration. Calls store.logout(), clears query cache, navigates
to /login. Server-call failures swallowed; local state still flips
to anonymous.
- src/auth/cross-tab-sync.ts: startCrossTabSync(). Subscribes to the
auth store and bumps trm-auth-version in localStorage on status
transitions; listens for storage events and re-runs initialize()
when another tab bumps. Idempotent via module-level guard. No-ops
if localStorage is unavailable.
- src/ui/components/logout-button.tsx: <LogoutButton> wraps shadcn
Button. Pass-through props but locks onClick / disabled / children.
Local isLoggingOut for "Signing out..." indicator + double-click
guard.
- src/auth/bootstrap.tsx: <AuthBootstrap> now calls startCrossTabSync()
alongside the existing init steps. Single mount point.
- src/auth/index.ts: re-export performLogout + startCrossTabSync.
- src/routes/_authed/index.tsx: replaced the inline sign-out button
with <LogoutButton />. The existing useEffect on 'anonymous' status
handles navigation when cross-tab sync fires.
Bonus: tsconfig.app.json now has "strict": true. TanStack Router emits
a conditional-type error ("strictNullChecks must be enabled") in
editors when strict is off; tsc -b was lenient. Caught in 1.7's
review. Typecheck remained green after enabling.
TanStack Router file-based routes:
- vite.config.ts: TanStackRouterVite plugin (target: react,
autoCodeSplitting: true) before the React plugin.
- .gitignore: src/routeTree.gen.ts (auto-generated).
- src/lib/query-client.ts: module-level QueryClient singleton.
- src/routes/__root.tsx: root route, QueryClientProvider, Suspense-
wrapped router + query devtools (dev-only via import.meta.env.DEV).
- src/routes/login.tsx: public route. validateSearch schema accepts
optional redirect. LoginRoute wraps <LoginPage> with onAuthenticated
navigating to redirect ?? '/'.
- src/routes/_authed/route.tsx: pathless protected layout. beforeLoad
redirects to /login on 'anonymous'; falls through on 'unknown' /
'authenticating' so hard reload doesn't flash the login page.
- src/routes/_authed/index.tsx: placeholder home with sign-out button.
Cross-tab logout effect bounces to /login on store transition.
- src/App.tsx: replaced — now creates the router and renders
<RouterProvider />. The interim status-branching logic from 1.6 is
gone (the route tree handles it).
- eslint.config.js: override for src/routes/** disabling
react-refresh/only-export-components — TanStack Router's file-based
pattern intentionally co-exports Route alongside components.
Code-splitting working: login chunk 37KB, home + auth 17KB, card
primitive 31KB, all loaded lazily; main bundle 353KB.
Deviations:
1. No top-level useRequireAuth hook — per-page useEffect on store
transitions is just as effective and only used in one place.
2. ESLint override for src/routes/** matches the existing pattern for
src/ui/primitives/**.
3. Login page's auto-navigate effect from 1.6 is removed — the route
wrapper owns navigation via onAuthenticated.
