feat: Enhance position description handling in TrainDataView and TrainPosition components

feat: Implement official position metadata handling and caching
- Add `currentTrainMetadata.ts` to manage carrying forward official position metadata between train snapshots. - Introduce `lineDisplayName.ts` for mapping line IDs to display names. - Create `officialPositionCache.ts` for parsing and serializing official position data with cache validation. - Enhance `officialPositionService.ts` to support persistent caching of official positions and improve resolver functionality. - Update `requestCoordinator.ts` to allow cancellation of polling requests without disposing of the coordinator. - Modify `trainTimeFiltering.ts` to incorporate line ID context when checking for duplicate train data. - Refactor `useCurrentTrain.tsx` to support polling for current train data with official position enrichment. - Add tests for new features, including persistent cache behavior and handling of ambiguous train data.

+# Expo Animation Recipes
+
+Ready-to-build implementations for the cases that come up most in a React Native app. Start from the recipe, then adapt.
+
+---
+
+## Setup the recipes assume
+
+```bash
+npx expo install react-native-reanimated react-native-worklets react-native-gesture-handler expo-haptics
+```
+
+(`react-native-keyboard-controller` only for the keyboard recipe.) `expo install`, not `npm install` — it resolves the versions that match the SDK. The worklets Babel plugin is configured by `babel-preset-expo` automatically.
+
+`GestureHandlerRootView` wraps the app once — in Expo Router, the root `_layout`:
+
+```jsx
+import { GestureHandlerRootView } from 'react-native-gesture-handler';
+
+export default function RootLayout() {
+  return (
+    <GestureHandlerRootView style={{ flex: 1 }}>
+      <Stack />
+    </GestureHandlerRootView>
+  );
+}
+```
+
+Imports and constants every recipe below shares:
+
+```js
+import { useState, useEffect, useMemo } from 'react';
+import Animated, {
+  useSharedValue, useAnimatedStyle, useAnimatedScrollHandler, useAnimatedReaction,
+  withSpring, withTiming, interpolate, Extrapolation, Easing,
+  FadeInDown, FadeOutDown, LinearTransition,
+} from 'react-native-reanimated';
+import { Gesture, GestureDetector } from 'react-native-gesture-handler';
+import { scheduleOnRN } from 'react-native-worklets';
+import * as Haptics from 'expo-haptics';
+
+const EASE_OUT = Easing.bezier(0.23, 1, 0.32, 1);      // strong ease-out for UI
+const EASE_IN_OUT = Easing.bezier(0.77, 0, 0.175, 1);  // on-screen movement
+const EASE_SHEET = Easing.bezier(0.32, 0.72, 0, 1);    // iOS sheet curve
+```
+
+Three conventions, explained once here instead of in every recipe:
+
+- **Shared values are read and written with `.get()` / `.set()`**, the form the Reanimated docs recommend for React Compiler support. `.value` still works, but the compiler can't see through it.
+- **`scheduleOnRN(fn, ...args)` replaces the deprecated `runOnJS(fn)(...args)`** for calling back to the React Native runtime from a worklet.
+- **Gestures are wrapped in `useMemo`.** Rebuilding a gesture on every render can reattach the recognizer and drop a drag that's mid-flight.
+
+**Gesture Handler v3:** Expo installs v2, and the recipes use its `Gesture.Pan()` builder. If the project is already on v3, the builder is legacy — each gesture is a hook taking one config object, with `onStart` → `onActivate`, `onEnd` → `onDeactivate`, and the `success` flag replaced by `event.canceled` (inverted). The hook manages its own identity, so drop the `useMemo`:
+
+```jsx
+const pan = usePanGesture({
+  activeOffsetY: [-10, 10],
+  onActivate: () => { context.set(translateY.get()); },
+  onUpdate: (e) => { translateY.set(context.get() + e.translationY); },
+  onDeactivate: (e) => { /* settle with withSpring as below */ },
+});
+```
+
+---
+
+## Two worklets you'll need everywhere
+
+Momentum projection decides *where a flick was going*, so a fast short swipe commits and a slow long one doesn't. Rubber-banding makes a boundary resist instead of stopping dead.
+
+```js
+// Where the finger would come to rest if it kept decelerating.
+// Apple's exponential-decay form — not the v²/2a from physics class.
+function project(velocity, decelerationRate = 0.998) {
+  'worklet';
+  return ((velocity / 1000) * decelerationRate) / (1 - decelerationRate);
+}
+
+// The further past the edge, the less the element follows.
+function rubberband(overshoot, dimension, constant = 0.55) {
+  'worklet';
+  return (overshoot * dimension * constant) / (dimension + constant * Math.abs(overshoot));
+}
+```
+
+---
+
+## Press feedback
+
+Every pressable in the app. This passes the frequency gate only because it's near-imperceptible: 120ms and a 3% scale is the ceiling for something touched this often — anything longer or larger belongs to rarer moments, per step 1 in SKILL.md. No gesture, no shared value — a CSS transition is the whole implementation.
+
+```jsx
+import Animated from 'react-native-reanimated';
+import { Pressable, StyleSheet } from 'react-native';
+
+function PressableScale({ onPress, children }) {
+  const [pressed, setPressed] = useState(false);
+  return (
+    <Pressable
+      onPress={onPress}
+      onPressIn={() => setPressed(true)}
+      onPressOut={() => setPressed(false)}
+      hitSlop={12}
+      pressRetentionOffset={16}
+    >
+      <Animated.View style={[styles.box, pressed && styles.pressed]}>{children}</Animated.View>
+    </Pressable>
+  );
+}
+
+const styles = StyleSheet.create({
+  box: {
+    transform: [{ scale: 1 }],
+    transitionProperty: 'transform',
+    transitionDuration: '120ms',
+    transitionTimingFunction: 'cubic-bezier(0.23, 1, 0.32, 1)',
+  },
+  pressed: { transform: [{ scale: 0.97 }] },
+});
+```
+
+`setState` is fine here — it fires twice per press, not per frame. `hitSlop` brings a small icon up to the 44pt target without growing it; `pressRetentionOffset` stops a slight finger drift from cancelling.
+
+---
+
+## Bottom sheet you can drag to dismiss
+
+Before writing this: if the sheet is its own destination, use `presentation: 'formSheet'` (see **Screen transitions**) and get the platform's real sheet for free. Build this only when the sheet has to live inside an existing screen.
+
+```jsx
+const translateY = useSharedValue(0);
+const context = useSharedValue(0);
+
+const pan = useMemo(() => Gesture.Pan()
+  .activeOffsetY([-10, 10])   // let a horizontal swipe win; require intent before committing
+  .onStart(() => {
+    context.set(translateY.get());   // start from the current on-screen value, not from 0
+  })
+  .onUpdate((e) => {
+    const next = context.get() + e.translationY;
+    // downward is free; upward past the top resists
+    translateY.set(next >= 0 ? next : rubberband(next, HEIGHT));
+  })
+  .onEnd((e) => {
+    const projected = translateY.get() + project(e.velocityY);
+    if (projected > HEIGHT * 0.4) {
+      translateY.set(withSpring(HEIGHT, {
+        duration: 300, dampingRatio: 1, velocity: e.velocityY, overshootClamping: true,
+      }, (finished) => { if (finished) scheduleOnRN(onClose); }));
+    } else {
+      translateY.set(withSpring(0, { duration: 300, dampingRatio: 0.8, velocity: e.velocityY }));
+      scheduleOnRN(Haptics.impactAsync, Haptics.ImpactFeedbackStyle.Light);   // it snapped home
+    }
+  }), [onClose]);
+
+const sheetStyle = useAnimatedStyle(() => ({ transform: [{ translateY: translateY.get() }] }));
+```
+
+The four details that separate this from a bad drag:
+
+- **`onStart` captures the current value.** Without it, grabbing a sheet mid-animation teleports it — the animation must continue from where the eye last saw it.
+- **Velocity decides, not distance.** `project()` means a quick flick dismisses even a few pixels down. Requiring 40% travel makes the sheet feel heavy.
+- **Velocity is handed to the spring**, so there's no seam between the finger releasing and the animation continuing. This is the single detail that most separates "fluid" from "fine".
+- **`overshootClamping` on dismissal** — otherwise the sheet springs past the bottom of the screen and flashes a gap.
+
+The backdrop derives from the same value, so it's always in sync and costs nothing:
+
+```jsx
+const backdropStyle = useAnimatedStyle(() => ({
+  opacity: interpolate(translateY.get(), [0, HEIGHT], [1, 0], Extrapolation.CLAMP),
+}));
+```
+
+---
+
+## Swipe to delete a row
+
+Before writing this: gesture-handler ships [`ReanimatedSwipeable`](https://docs.swmansion.com/react-native-gesture-handler/docs/components/reanimated_swipeable/), which already does swipe-to-reveal actions — thresholds, overshoot, open/close methods — on the UI thread. Reach for it when the row reveals action buttons. Build the gesture yourself only when the interaction is different in kind: swipe-to-commit with momentum projection, like this one.
+
+```jsx
+const x = useSharedValue(0);
+const context = useSharedValue(0);
+
+const pan = useMemo(() => Gesture.Pan()
+  .activeOffsetX([-10, 10])   // must declare the axis, or it fights the vertical scroll
+  .onStart(() => { context.set(x.get()); })   // grab mid-spring continues from where the row is, not from 0
+  .onUpdate((e) => { x.set(Math.min(0, context.get() + e.translationX)); })
+  .onEnd((e) => {
+    const projected = x.get() + project(e.velocityX);
+    if (projected < -SWIPE_THRESHOLD) {
+      x.set(withTiming(-WIDTH, { duration: 200, easing: EASE_OUT }, (f) => {
+        if (f) scheduleOnRN(onDelete, id);
+      }));
+    } else {
+      x.set(withSpring(0, { duration: 300, dampingRatio: 1, velocity: e.velocityX }));
+    }
+  }), [onDelete, id]);
+```
+
+Closing the gap the deleted row left is the list's job, not the row's:
+
+```jsx
+const ROW_CLOSE = LinearTransition.duration(200);   // module scope — builders rebuilt in render cost every re-render
+
+<Animated.FlatList data={items} itemLayoutAnimation={ROW_CLOSE} ... />
+```
+
+`activeOffsetX` is the mobile-specific part. A pan handler inside a scroll view with no axis declared will steal vertical scrolls, and the list will feel broken in a way that looks like a scrolling bug rather than a gesture bug.
+
+---
+
+## Collapsing header on scroll
+
+```jsx
+const scrollY = useSharedValue(0);
+const onScroll = useAnimatedScrollHandler((e) => { scrollY.set(e.contentOffset.y); });
+
+const titleStyle = useAnimatedStyle(() => ({
+  opacity: interpolate(scrollY.get(), [0, 60], [1, 0], Extrapolation.CLAMP),
+  transform: [{ translateY: interpolate(scrollY.get(), [0, 60], [0, -12], Extrapolation.CLAMP) }],
+}));
+
+<Animated.ScrollView onScroll={onScroll} scrollEventThrottle={16}>
+```
+
+**Never animate the header's `height` to collapse it.** That runs a layout pass on the header and everything below it on every scroll frame — the one animation guaranteed to stutter, because it's competing with the scroll itself. Give the container a fixed height and translate the content inside it, clipping with `overflow: 'hidden'`.
+
+`Extrapolation.CLAMP` is not optional: without it, scrolling past 60 keeps driving opacity negative and the header reappears inverted at the bottom of a long list.
+
+---
+
+## List entrances
+
+```jsx
+// The Reanimated docs recommend building layout animations outside components,
+// or in useMemo — an inline chain in JSX rebuilds the builder on every render.
+// A per-index delay can't live at module scope, so the row memoizes its own:
+function Row({ item, index }) {
+  const entering = useMemo(() => FadeInDown.duration(250).delay(index * 40), [index]);
+  return <Animated.View entering={entering}>{/* ... */}</Animated.View>;
+}
+
+{items.map((item, i) => <Row key={item.id} item={item} index={i} />)}
+```
+
+Stagger 30–80ms. Longer feels slow, shorter reads as simultaneous.
+
+**Never put `entering` on a row inside `FlatList`, `FlashList`, or any virtualized list.** Rows are recycled, so the animation re-fires every time one scrolls back into view — the list appears to flicker while the user scrolls. Animate the list container once on mount, or use `itemLayoutAnimation` for reflow only.
+
+Entrance animations are for content the user asked for and is waiting on. A list they scroll past all day should already be there.
+
+---
+
+## Keyboard-synced UI
+
+Needs its own module and a one-time provider ([Expo keyboard guide](https://docs.expo.dev/guides/keyboard-handling/)):
+
+```bash
+npx expo install react-native-keyboard-controller
+```
+
+```jsx
+import { KeyboardProvider } from 'react-native-keyboard-controller';
+
+// Root _layout, next to GestureHandlerRootView — hooks below do nothing without it.
+<KeyboardProvider>
+  <Stack />
+</KeyboardProvider>
+```
+
+```jsx
+import { useReanimatedKeyboardAnimation } from 'react-native-keyboard-controller';
+
+const { height } = useReanimatedKeyboardAnimation();   // 0 → -keyboardHeight, on the UI thread
+const footerStyle = useAnimatedStyle(() => ({ transform: [{ translateY: height.get() }] }));
+```
+
+Never build this from `Keyboard.addListener` plus a timing animation. The keyboard rides a private system curve, the event arrives on the JS thread after the keyboard has already started moving, and any duration you pick will visibly lag or lead it. The UI must be driven by the keyboard's actual position, frame by frame.
+
+---
+
+## Tab / segmented indicator
+
+Measure once, then animate transforms.
+
+```jsx
+const [layouts, setLayouts] = useState({});   // measured with onLayout, not per frame
+const x = useSharedValue(0);
+const w = useSharedValue(0);
+
+useEffect(() => {
+  const l = layouts[active];
+  if (!l) return;
+  x.set(withTiming(l.x, { duration: 250, easing: EASE_IN_OUT }));
+  w.set(withTiming(l.width, { duration: 250, easing: EASE_IN_OUT }));
+}, [active, layouts]);
+
+const pillStyle = useAnimatedStyle(() => ({
+  transform: [{ translateX: x.get() }],
+  width: w.get(),
+}));
+```
+
+This is the sanctioned `width` animation: the pill is absolutely positioned with no children, so nothing else re-lays-out, and its corner radius survives — `scaleX` would smear the corners into ovals.
+
+`ease-in-out`, because the pill is moving across the screen rather than entering or leaving it. Fire `Haptics.selectionAsync()` on the press, not when the pill lands.
+
+---
+
+## Screen transitions (Expo Router)
+
+Configure the native stack. Never rebuild a screen transition in JS: the native one runs on the platform side, keeps the interactive back gesture, and matches every other app on the device.
+
+```jsx
+<Stack screenOptions={{ animation: reduced ? 'fade' : 'default' }}>
+  <Stack.Screen name="settings" options={{ animation: 'slide_from_right', animationMatchesGesture: true }} />
+  <Stack.Screen name="compose" options={{ presentation: 'modal' }} />
+  <Stack.Screen name="filter" options={{
+    presentation: 'formSheet',
+    sheetAllowedDetents: 'fitToContents',
+    sheetGrabberVisible: true,
+  }} />
+</Stack>
+```
+
+| Navigation | Option |
+| --- | --- |
+| Deeper into a hierarchy | `animation: 'default'` — the platform push, unmodified |
+| A self-contained task the user can abandon | `presentation: 'modal'` |
+| A short interruption: picker, filter, share | `presentation: 'formSheet'` with detents |
+| Between tabs | `animation: 'none'` |
+| Reduced motion | `animation: 'fade'` |
+
+`animationMatchesGesture: true` makes the iOS back swipe run your transition in reverse under the finger, instead of the default push. Set it whenever you set a custom `animation`, or dragging back looks like a different app than pushing forward.
+
+`formSheet` is native on both platforms, but not the same on both — the [Expo modal docs](https://docs.expo.dev/router/advanced/modals/#form-sheet-presentation) have the full list:
+
+- **Android caps detents at three.** A longer `sheetAllowedDetents` array works on iOS and silently truncates on Android — design for three.
+- **`sheetGrabberVisible` is iOS-only.** Android shows no grabber; don't rely on it as the only "this is draggable" affordance.
+- **Android form sheets can't host native headers or nested stacks.** Keep the sheet's content a single screen; if it needs its own navigation, use `presentation: 'modal'` instead.
+- **`fitToContents` needs explicitly sized content.** A `flex: 1` root has no intrinsic height to fit — size the content, or the detent is wrong.
+
+---
+
+## Toast
+
+```jsx
+// Module scope — layout-animation builders live outside the component.
+const TOAST_ENTER = FadeInDown.duration(300).easing(EASE_OUT);
+const TOAST_EXIT = FadeOutDown.duration(250).easing(EASE_OUT);
+
+<Animated.View
+  entering={TOAST_ENTER}
+  exiting={TOAST_EXIT}
+  style={{ position: 'absolute', bottom: insets.bottom + 16, left: 16, right: 16 }}
+/>
+```
+
+- **The 300ms cap holds here too.** A toast isn't an exception — it's uninvited, so if anything it should be quicker and quieter than motion the user asked for.
+- **It exits the way it entered.** Entering from the bottom and leaving to the side reads as two unrelated elements.
+- **Exit ~20% faster than entry.** The user has finished reading; the arrival deserves the time, the departure doesn't.
+- **Safe area insets, always.** A toast at `bottom: 16` sits under the home indicator on every modern iPhone.
+
+If toasts stack and the list reflows, add `itemLayoutAnimation` and expect to tune the opacity against the reflow by eye — there's no formula for that pair. Look at it again the next day.
+
+---
+
+## Firing something once at a threshold
+
+When a crossing point matters — a detent, a snap, a pull-to-refresh arming — don't poll it from JS and don't `scheduleOnRN` every frame.
+
+```jsx
+const armed = useSharedValue(false);
+
+useAnimatedReaction(
+  () => pullDistance.get() > REFRESH_THRESHOLD,
+  (isArmed, wasArmed) => {
+    if (isArmed !== wasArmed) {
+      armed.set(isArmed);
+      scheduleOnRN(Haptics.impactAsync, Haptics.ImpactFeedbackStyle.Light);
+    }
+  }
+);
+```
+
+The comparison runs on the UI thread every frame; the JS call happens twice per pull. That's the pattern for every "do something when the animation reaches X".

+name: animate-expo
+description: Build animations in React Native and Expo, making the decisions in the order that determines whether they feel right — should it animate, which thread it runs on, which properties, spring or timing, how the gesture hands off, how it degrades. Writes the implementation with Reanimated, Gesture Handler, Expo Router and expo-haptics. Use when animating anything in an Expo app, adding gestures, sheets, screen transitions, press feedback or haptics, or fixing motion that stutters on device. For web animation use `animate`.
+---
+
+# Building Animations in Expo
+
+A construction skill for React Native. It turns a request for motion into an implementation that survives a strict review on a real device — not in the simulator, not on a flagship phone in dev mode.
+
+Mobile changes three things about animation, and everything in this skill follows from them:
+
+1. **There is no hover.** Every affordance the web puts in hover has to live in press, position, or nothing.
+2. **There are two runtimes.** Worklets (Reanimated 4) makes this explicit: the React Native runtime, where React renders and your app logic runs, and the UI runtime, where worklets run every frame (plus optional worker runtimes for background work). An animation that touches the RN runtime stutters the moment the app does anything else. The whole craft is keeping motion on the UI runtime.
+3. **The user's finger is on the element.** Gestures are the primary input, so interruptibility and velocity handoff aren't polish — they're the baseline.
+
+## Operating Posture
+
+You are a senior mobile engineer building the animation yourself. Make the call, state the reasoning in one line, write the code. Never present motion options as a menu.
+
+Two failure modes, and the first is worse:
+
+1. **Animating something that shouldn't animate.** The gate below exists to produce zero lines of code sometimes.
+2. **Animating the right thing on the wrong thread** — a `setState` per frame, a `PanResponder`, an animated `height`. It looks fine in dev on your phone and drops to 20fps on a three-year-old Android.
+
+## Hard Rules
+
+1. **Run the sequence in order.** Steps 1 and 2 gate everything.
+2. **Reanimated, not core `Animated`.** Core `Animated` can't be driven by a gesture without crossing the bridge, and `useNativeDriver` refuses anything but transform and opacity anyway. Reanimated worklets run on the UI thread and keep running while JS is busy.
+3. **No approximated values.** Curves and spring configs come from the tables below.
+4. **Reduced motion ships with the animation**, not as a follow-up.
+5. **Feel is judged on a release build on the slowest device you support.** Nothing else counts as verified.
+
+## The Build Sequence
+
+### 1. Should this animate at all?
+
+| Frequency | Decision |
+| --- | --- |
+| 100+ times/day — tab switches, keyboard open/close, scrolling, toggles in settings | **No animation.** Platform default or nothing. Stop here. |
+| Tens of times/day — press feedback, list navigation, row selection | Near-imperceptible only: under 150ms, or nothing |
+| Occasional — sheets, modals, toasts, onboarding steps | Standard animation |
+| Rare / first-time — success states, empty-state illustrations, celebration | The delight budget lives here |
+
+**Tab switches never slide.** Tabs are peers, not a hierarchy — sliding implies depth that isn't there, and the user pays for it dozens of times a session. `animation: 'none'`.
+
+If the request fails this gate, say so and don't write it.
+
+### 2. What is the purpose?
+
+Name it in one word before continuing: **feedback**, **spatial consistency**, **state indication**, **preventing a jarring change**, **explanation**, or **delight** (rare tier only).
+
+Can't name it? Don't build it.
+
+### 3. Pick the tool — cheapest that works
+
+Walk down; stop at the first that fits.
+
+| Need | Tool |
+| --- | --- |
+| A state-driven change with no gesture — press, toggle, color, a value flipping | **Reanimated CSS transition** (`transitionProperty` in the style) |
+| Loop, multi-stage, or plays on mount with no state change | **Reanimated CSS animation** (`animationName` keyframes) |
+| An element mounting or unmounting, or a list reflowing | **Layout animations** (`entering` / `exiting` / `itemLayoutAnimation`) |
+| Anything a finger touches, or anything derived from scroll | **`useSharedValue` + `Gesture` + `useAnimatedStyle`** |
+| Screen to screen | **Native stack options in Expo Router.** Never hand-roll this |
+| A bottom sheet that is its own screen | **`presentation: 'formSheet'`** — it's a real UISheetPresentationController, free and correct |
+| Tab bar | **`NativeTabs`** (from `expo-router/unstable-native-tabs`) — the platform's real tab bar, its behaviors and transitions included |
+| Context menu, press-and-hold preview | **`Link.Menu` / `Link.Preview`** (Expo Router, iOS-only) — native menus and peek, never rebuilt in JS |
+| Header that collapses into a large title | **`headerLargeTitleEnabled`** on the native stack (iOS-only; `headerLargeTitle` is deprecated) — not a scroll worklet |
+| Pull to refresh | **`RefreshControl`** — hand-roll only when it's a signature interaction (see the threshold recipe) |
+| UI that tracks the keyboard | **`react-native-keyboard-controller`** — the keyboard's real position, frame by frame, on the UI thread |
+| Vector illustration, celebration, empty state | **Lottie** — for illustration only, never for UI state |
+| A huge animated scene, freeform drawing | **`@shopify/react-native-skia`** — a canvas, for when the view hierarchy itself is the bottleneck |
+
+Reach for a shared value only when the value is continuous or interruptible. A press scale is a CSS transition; a drag is a shared value. Using a worklet for a two-state toggle is the mobile equivalent of installing a motion library for a fade.
+
+**Dependencies.** Install with `npx expo install <package>` — it resolves the version that matches the project's SDK, which plain `npm install` won't:
+
+| Need | Package |
+| --- | --- |
+| Animation | `react-native-reanimated` + `react-native-worklets` |
+| Gestures | `react-native-gesture-handler` |
+| Navigation, sheets, native tabs, menus | `expo-router` |
+| Haptics | `expo-haptics` |
+| Keyboard-following UI | `react-native-keyboard-controller` (needs `KeyboardProvider` at the root — see the keyboard recipe) |
+| Illustration, celebration | `lottie-react-native` |
+| Very large animated scenes, custom drawing | `@shopify/react-native-skia` |
+
+### 4. Pick the properties
+
+- **`transform` and `opacity` are free.** Everything else is a layout pass. `width`, `height`, `margin`, `padding`, `flex`, `top`, `left`, `gap` re-run Yoga on every frame for that node *and its siblings*.
+- **The one exception: an absolutely positioned element with no children** — a tab pill, a progress bar fill. It's out of flow, so nothing else re-lays-out, and animating `width` keeps the corner radius that `scaleX` would smear.
+- **Never `scale(0)`.** Start from `scale(0.9–0.97)` + `opacity: 0`. Nothing in the real world appears from nothing.
+- **`transform` is an array and order matters** — `[{ translateY }, { scale }]` scales after moving; reversed, the translate gets scaled too. Keep translate first unless you want the multiplication.
+- **Android shadows are `elevation`, and animating elevation re-renders the shadow every frame.** Animate opacity of a pre-shadowed layer instead.
+- **Never animate `BlurView` intensity.** On Android it re-renders the blur each frame. Crossfade the opacity of a static `BlurView` instead.
+- **Percentages work in `translate`** and are relative to the element's own size — `translateY('100%')` moves a sheet by its own height whatever its content.
+
+### 5. Timing or spring
+
+**If a finger was involved, use a spring.** Springs carry velocity through an interruption; timing curves restart. Everything else uses timing.
+
+Reanimated's spring takes Apple's two designer parameters directly — use this form, not mass/stiffness/damping:
+
+| Interaction | Config |
+| --- | --- |
+| Default settle, no overshoot | `{ duration: 400, dampingRatio: 1 }` |
+| Reposition / snap back after a drag | `{ duration: 400, dampingRatio: 0.8, velocity }` |
+| Sheet, drawer | `{ duration: 300, dampingRatio: 0.8, velocity }` |
+| Must not pass a hard edge | add `overshootClamping: true` |
+
+**Bounce only when the gesture carried momentum.** Overshoot on a menu that faded in feels wrong; overshoot on a card you flicked feels right.
+
+**Easing**, for everything without a finger on it:
+
+| Situation | Easing |
+| --- | --- |
+| Entering or exiting | `ease-out` |
+| Moving / morphing on screen | `ease-in-out` |
+| Constant motion (progress, marquee) | `linear` |
+| Default | `ease-out` |
+
+**Never `ease-in` on UI.** It starts slow, delaying the exact moment the user is watching. Reanimated's built-ins are as weak as CSS's — use these:
+
+```js
+import { Easing } from 'react-native-reanimated';
+
+const EASE_OUT = Easing.bezier(0.23, 1, 0.32, 1);      // strong ease-out for UI
+const EASE_IN_OUT = Easing.bezier(0.77, 0, 0.175, 1);  // on-screen movement
+const EASE_SHEET = Easing.bezier(0.32, 0.72, 0, 1);    // iOS sheet curve
+```
+
+**Duration:**
+
+| Element | Duration |
+| --- | --- |
+| Press feedback | 100–150ms |
+| Toggle, chip, small state change | 150–200ms |
+| Sheet, modal, drawer | spring, ~300ms perceived |
+| Screen transition | the platform default — don't override it |
+
+Mobile UI animations stay under 300ms, same as web. The platform's own transitions are longer (iOS push is 350ms); match the platform for navigation, beat it everywhere else.
+
+### 6. Keep it off the JS thread
+
+This is the mobile-specific craft, and it's where most React Native motion dies.
+
+- **Never `setState` from a gesture or scroll handler.** One React render per frame is the single biggest cause of jank in RN apps. Shared value → `useAnimatedStyle`, and React never re-renders at all.
+- **Never schedule back to the RN runtime inside `onUpdate` or a scroll handler.** `scheduleOnRN(fn, ...args)` from `react-native-worklets` — the Reanimated 4 replacement for the deprecated `runOnJS(fn)(...args)` — queues an RN-runtime call, and in `onUpdate` that's 60–120× per second. It belongs in `onEnd`, or in a `useAnimatedReaction` that fires when a value crosses a threshold.
+- **Never read a shared value during render** (`translateY.get()` in JSX). It's a snapshot that never updates and it silently desyncs. **Never write one during render either** — it fires mid-reconciliation, and a re-render you didn't cause replays the write. Touch shared values only in worklets, handlers, and effects.
+- **Use `.get()` / `.set()`, not `.value`.** Same API, but direct `.value` access is the form the React Compiler can't see through — the Reanimated docs call `get`/`set` the compiler-safe way. `set` also takes a functional update: `sv.set((v) => v + 1)`.
+- **Functions called from a worklet need `'worklet'`** as their first line, or they throw at runtime on device while working fine in the debugger.
+
+### 7. Press, not hover
+
+Every hover affordance from the web has to be redesigned, not ported.
+
+- **Feedback on press-in, commit on press-out.** Waiting for the tap to complete before showing anything feels dead — this is the latency the user actually perceives.
+- **`scale: 0.97` in 100–150ms** on any pressable, `Pressable` + a CSS transition. `scale` takes the label and icons with it, which is what makes it read as physical.
+- **44×44pt minimum touch target** (48dp Android). If the visual is smaller, add `hitSlop` — don't grow the visual.
+- **`pressRetentionOffset`** so a finger drifting a few pixels doesn't cancel a press the user meant.
+- **Android ripple only in a Material-styled app.** In a custom-designed app, the same scale on both platforms is more coherent than a ripple on one.
+
+### 8. Haptics
+
+Mobile has a sense the web doesn't. Use it sparingly and it becomes the thing that makes the app feel expensive; use it everywhere and users turn it off.
+
+| Moment | Call |
+| --- | --- |
+| A value ticks past a step — picker, slider detent, segmented control | `Haptics.selectionAsync()` |
+| Something snaps home, a sheet detent catches, a drag commits | `Haptics.impactAsync(ImpactFeedbackStyle.Light)` |
+| A heavy object lands, a destructive action fires | `Haptics.impactAsync(ImpactFeedbackStyle.Medium)` |
+| Operation succeeded or failed | `Haptics.notificationAsync(NotificationFeedbackType.Success / Error)` |
+
+Three rules, and they're absolute:
+
+- **Same frame as the visual.** A haptic that lags its animation reads as a glitch, not as feedback. Fire it at the causal moment — the detent catching — not when the animation finishes.
+- **One per user action.** Never on scroll, never per frame, never on an entrance animation the user didn't cause.
+- **Never the only feedback.** Haptics are off system-wide for many users, and silent on most Android hardware. The visual has to stand alone.
+
+From a worklet, haptics must be scheduled back to the RN runtime: `scheduleOnRN(Haptics.selectionAsync)`.
+
+### 9. Reduced motion and accessibility
+
+```jsx
+import { useReducedMotion, ReduceMotion, withSpring } from 'react-native-reanimated';
+
+const reduced = useReducedMotion();
+const y = useSharedValue(reduced ? 0 : SHEET_HEIGHT);
+
+// or let each animation decide
+withSpring(0, { duration: 300, dampingRatio: 0.8, reduceMotion: ReduceMotion.System });
+```
+
+Reduced motion means **fewer and gentler**, not zero: keep opacity and color changes that explain a state change, drop translation, scale, parallax and overshoot. Screen transitions become `animation: 'fade'`.
+
+**Text scales.** `allowFontScaling` is on by default, so any height you measured at default type size is wrong at 200%. Never animate to a hardcoded height — measure with `onLayout`, or animate a transform instead.
+
+## Setup that silently breaks motion
+
+Check these first when "the animation just doesn't run":
+
+- Install through Expo so versions match the SDK: `npx expo install react-native-reanimated react-native-worklets`. In an Expo project, `babel-preset-expo` configures the worklets Babel plugin automatically — no `babel.config.js` step. Only a bare RN project without that preset adds the plugin manually, and there it must be last in the list. A missing or misplaced plugin doesn't silently fall back anymore — it throws `Failed to create a worklet` at runtime.
+- `GestureHandlerRootView` must wrap the app, or gestures do nothing with no error.
+- Reanimated 4 requires the New Architecture.
+- **Expo Go is not a performance environment.** Judge feel in a release build; a dev build's JS thread is slow enough to hide exactly the problems you're looking for.
+
+## 120fps
+
+On ProMotion iPhones, third-party animations are capped at 60fps unless `CADisableMinimumFrameDurationOnPhone` is set. Recent Expo SDKs set it by default — confirm it's there, and add it if not:
+
+```json
+{ "expo": { "ios": { "infoPlist": { "CADisableMinimumFrameDurationOnPhone": true } } } }
+```
+
+Then the frame budget is 8ms, not 16. This is also why a UI-thread animation matters more on mobile than it does on web.
+
+## Recipes
+
+For ready-to-build implementations — press feedback, drag-to-dismiss sheet, swipe-to-delete, collapsing header, list entrances, keyboard-synced UI, tab indicator, screen transitions — see [RECIPES.md](RECIPES.md). Load it whenever the request matches one; start from the recipe rather than from a blank file.
+
+## Never Ship
+
+| Never | Instead |
+| --- | --- |
+| `PanResponder` | `Gesture.Pan()` from gesture-handler |
+| `setState` in a gesture or scroll handler | shared value + `useAnimatedStyle` |
+| `runOnJS` (deprecated in Reanimated 4) | `scheduleOnRN` from `react-native-worklets` |
+| `scheduleOnRN` per frame | `onEnd`, or `useAnimatedReaction` at a threshold |
+| Reading or writing a shared value during render | `.get()` / `.set()` in worklets, handlers, effects |
+| Core `Animated` for anything a finger touches | Reanimated |
+| Animating `height` / `width` / `margin` / `flex` / `top` | `transform` + `opacity` (absolute, childless elements exempt) |
+| Animating `BlurView` intensity or Android `elevation` | crossfade a static layer |
+| `entering` on a virtualized list row | animate the container, or `itemLayoutAnimation` |
+| A screen transition rebuilt in JS | native stack `animation` |
+| Sliding between tabs | `animation: 'none'` |
+| `Easing.in(...)` on a UI element | `Easing.bezier(0.23, 1, 0.32, 1)` |
+| `scale(0)` entrance | `scale(0.95)` + `opacity: 0` |
+| Distance-only dismissal threshold | velocity **or** distance — a flick is enough |
+| Hard stop at a boundary | rubber-band resistance |
+| A haptic per frame, or as the only feedback | one per commit, always paired with a visual |
+| Judging feel in Expo Go or the simulator | release build, slowest supported device |
+
+## Output
+
+Write the code. Then, in at most a few lines:
+
+- **The gate result** — frequency tier and named purpose. Say what you rejected and why.
+- **The ingredients** — tool, properties, spring or curve + duration, thread.
+- **What to feel-check on device** — gestures, velocity handoff and haptic timing cannot be judged from code. Name what to try: flick it, interrupt it mid-flight, reverse it, run it on the slowest Android you have.
+
+The code is the deliverable. Don't pad it into a report.
+
+## Tone
+
+Opinionated and brief. When the honest answer is "this shouldn't animate," or "this needs a real device before I can tell you if it's right," give it.

+
+このskillは、現在のversionやchannelを固定するためではなく、変更判断の順序と恒久ルールを提供する。
+
+## 先に確認するsource of truth
+
+実装前に次を現行ファイル・read-only状態として確認する。
+
+- `AGENTS.md`
+- `package.json`、`yarn.lock`、`app.json`、`eas.json`
+- `docs/refactor-audit/`の該当資料
+- `docs/architecture/adr/`と`docs/release/release-matrix.md`
+- 必要な場合はEASのbinary、runtime、channel、profile、Updateの実測
+
+SDK、app version、build number、runtimeVersion、channel名はskillへ埋め込まない。現在値はsource of truthから読み、変更後の値と確認日を報告する。
+
+## 恒久ルール
+
+- React Navigationを明示的な依頼なしにExpo Routerへ移行しない。
+- Navigation workaroundを削除・変更する前にgit historyと回帰テストを確認する。
+- API responseをScreenから直接長期保持せず、通信・parser・domain adapterの境界を置く。
+- 既存fallback API、observability、native lifecycle workaroundを理由なく削除しない。
+- polling requestはowner、source、generation、fetchedAtを明示し、重複・late response・unmount後commitを防ぐ。
+- Native module、target、config plugin、permission、entitlement、native依存を変えるときは、OTAだけで配信せずruntime/build互換性を確認する。
+- JS-only変更でも、対象binaryが必要なnative APIとassetを持つことを確認してからOTAする。
+
+## 変更手順
+
+1. 監査Findingと対象コードの現状を再確認する。
+2. ADRまたは小さなcontractを先に書き、変更範囲を限定する。
+3. 既存navigation、fallback、mock/recording、observabilityを保った小さな実装にする。
+4. typecheck、lint、unit testを実行し、必要ならexpo-doctorをinformationalに実行する。
+5. native変更の有無、対象runtime、必要なDevelopment/Preview/Production Build、OTA可否を報告する。

+---
+
+# JR四国アプリ data-model skill
+
+このskillは全データ移行を指示するものではない。identityと時刻の境界を先に決め、既存legacy処理を段階的にadapterへ寄せるために使う。
+
+## 正本
+
+- 型とpure helper: `lib/domain/railway.ts`
+- 契約書: `docs/architecture/domain-model.md`
+- fixture: `tests/domainModel.test.ts`
+- Backendとの正式なmapping/schema: Backend/domain master。アプリ内の駅一覧からcanonical IDを推測しない。
+
+## Station identity
+
+- Physical Stationは現実の駅施設を表し、`PhysicalStationId`はBackend/domain masterが発行する。
+- Station Stopは路線・運行文脈ごとの停車点で、Physical Stationと別物である。
+- Station Numberは`Y00`、`T28`、`M12`などのlegacy/line-specific referenceであり、単独のcanonical IDにしない。
+- `adaptLegacyStationNumber()`は未解決の`physicalStationId: null`を返す。
+- legacy lookupが複数候補を返したとき、最初の候補を勝手に採用しない。line/backend mappingを確認する。
+
+## Train identity
+
+列車番号だけを長期keyにしない。少なくとも`trainNumber`、`serviceDate`、`lineId`、`source`を使い、必要ならoperatorやservice variantを加える。`trainIdentityKey()`の複合keyをfixtureで守る。
+
+## Railway time
+
+- Calendar Date、Service Date、Wall Clock Time、Service Minuteを別型・別責務にする。
+- `Wall Clock Time`は`00:00`〜`23:59`。24時台表記をJavaScript `Date`へ直接渡さない。
+- `parseServiceMinute()`は`00:00 = 0`、`24:30 = 1470`、`25:15 = 1515`のextended表記を整数分にする。
+- `serviceMinuteFromWallClock()`と`serviceDateFromCalendarDate()`は営業日境界を一つのpolicyとして扱う。既定値や境界時刻はBackend/運行ルールと照合する。
+
+## 実装時のガードレール
+
+- 既存`StationNumber`検索、WebView注入、運行情報parserを一括移行しない。
+- canonical mappingがない欠損・曖昧データを推測で結合しない。
+- API responseをScreenに長期保持せず、parser/adapterでcontractへ入れる。
+- contract変更には小さなfixture testを追加し、legacy adapterとBackend責任分界を文書化する。

+
+## 適用順序
+
+このリポジトリでは、次の優先順位で判断してください。
+
+1. ユーザーの明示的な依頼と安全上の制約
+2. 実際の `package.json`、`yarn.lock`、`app.json`、既存コードの現在の構成
+3. この `AGENTS.md` にあるJR四国アプリ固有のガードレール
+4. `.agents/skills/animate-expo/` にある外部Skillの一般的な設計指針
+
+Skillの例や推奨と実際のプロジェクト構成が衝突する場合は、アプリの構成とこのファイルを優先してください。互換性が不明な場合は、依存関係やnavigationを変更せず、まず現在のバージョンで利用可能なAPIを確認してください。
+
+## animate-expo Skill
+
+- Expo / React Nativeのanimation、gesture、sheet、screen transition、press feedback、hapticsを実装またはレビューするときは、まず `.agents/skills/animate-expo/SKILL.md` を読み、該当する場合は `RECIPES.md` も読みます。
+- これは開発エージェント向けのinstruction-only Skillです。アプリのruntime依存関係ではありません。Skill内のインストール例を理由に、依存関係、native設定、Babel設定、navigationを自動変更しないでください。
+- 導入元は [emilkowalski/skills](https://github.com/emilkowalski/skills) の `animate-expo`、確認時点の固定コミットは `d23d7f88a2e21c9e4b1418c7abe420f5c1052ba7`（2026-08-29）です。今回導入するSkillは `animate-expo` の2ファイルだけです。
+- `animate`、`ask-sonner`、`pick-ui-library` など他のSkillは、このリポジトリへ導入済みとは扱いません。
+
+## 現在の構成（current valuesは正本から確認）
+
+- 現行の主要世代は Expo SDK 57、React Native 0.86系、React 19系です。patch/minorをこのファイルへ固定せず、正確な値は `package.json` と `yarn.lock` から確認してください。
+- Reanimated、Worklets、Gesture Handlerなどのnative依存も、宣言値は `package.json`、解決値は `yarn.lock` を正本とします。
+- Expo Routerは未導入です。現行はReact Navigation 7（`NavigationContainer`、bottom tabs、stack）を直接構成しています。
+- Expo SDK 57 / React Native 0.86ではNew Architectureが既定です。現在の `app.json` に `newArchEnabled` の明示設定はありません。
+- ルートの `App.tsx` には既に `GestureHandlerRootView` があります。
+- `babel.config.js` には既存の `babel-preset-expo` と `react-native-reanimated/plugin` の設定があります。既存設定をSkillの説明だけで置き換えないでください。
+- `expo-haptics` は依存していますが、ソースコードでのruntime使用は確認できていません。依存の正確なversionは正本から確認してください。
+
+### animate-expo導入時のHistorical note
+
+animate-expo Skill導入時に参照したSDK・依存関係の基準は過去の検証記録です。現在のversionを示すものではなく、現在値は必ず `package.json` / `yarn.lock` を確認してください。
+
+## Source of truth
+
+- Expo、React、React Native、Reanimated、Worklets、その他の依存関係は、宣言値を `package.json`、解決値を `yarn.lock` で確認する。AGENTS.mdへpatch/minor versionを転記して正本にしない。
+- app version、iOS build number、Android versionCode、runtimeVersion、permission、entitlement、target、config pluginは `app.json` を確認する。
+- EAS profile、distribution、channel、environmentは `eas.json` を確認する。
+- 実際に配布されたbinary、runtime、channel、Update、audienceは、確認日付きのEAS CLI / EAS Dashboard観測を正本とする。リポジトリ設定からlive状態を推測しない。
+
+## JR四国アプリ固有のanimation / compatibilityガードレール
+
+- animationは目的ではなくUX改善の手段です。頻度、目的、情報理解への効果を確認し、不要なら追加しないでください。
+- 100回/日以上使う操作（タブ切替、スクロール、設定toggle、頻繁なデータ更新）に目立つanimationを追加しないでください。列車走行位置、運行情報、駅・列車データの更新や表示をanimationで遅延させないでください。
+- Reduced Motion / accessibilityを考慮し、translation、scale、parallax、overshootを含むanimationにはシステム設定に応じた低減経路を用意してください。既存のfont scaling制御もanimation導入のついでに変更しないでください。
+- gesture / scrollのframeごとにReactの`setState`、RN runtimeへのcallback、hapticsを実行しないでください。JS threadを不要にブロックせず、連続値はUI runtime側で処理します。
+- 高頻度更新UIでは再レンダリング、worklet、layout pass、メモリ、WebView負荷を確認し、animationを足す前後で体感と計測を比較してください。
+- 既存のReanimated、core `Animated`、`LayoutAnimation`、WebView内CSS animationは、それぞれの互換性・用途を確認せず一括移行しないでください。特に既存のcore `Animated`や `runOnJS` / `.value` の書き換えは別タスクとして扱います。
+- 新規のgesture / scroll連動の連続animationでは、現在のReanimated / Gesture HandlerのAPIを確認してUI thread駆動を優先します。現在のGesture Handlerはv2系なので、Skillのv3専用APIへ移行しないでください。
+- 既存のキーボード回避実装（`lib/useKeyboardAvoid.ts`）は、iOS/Androidのタイミング対策を含む保護された挙動です。`react-native-keyboard-controller` の追加や置き換えは、明示的な別依頼と実機検証なしに行わないでください。
+- 既存のnavigation設定とクラッシュ回避策を壊さないでください。とくに `App.tsx` のnative screens設定、`lib/stackOption.ts` のAndroid stack animation無効化、WebViewのライフサイクル制御をanimation改善だけで変更しないでください。
+- Expo Routerへの移行、native tabs / `formSheet` / `Link.Menu` の導入、navigationの大規模変更は今回のSkill適用範囲外です。
+- Expo SDK、React Native、Reanimatedのmajor version、New Architecture、既存navigationを、UI改善やSkill適用だけを理由に変更しないでください。新しい依存関係を追加する場合は、明示的な依頼と現在のSDKに対する互換性確認が必要です。
+- 画面遷移は既存のReact Navigation構成とプラットフォーム別設定を基準にし、既存のAndroid `animationEnabled: false` をSkillのRouter例で上書きしないでください。
+- hapticsは必要なユーザー操作に限り、視覚的なfeedbackの代替ではなく補助として1操作1回までにしてください。現在 `expo-haptics` は依存済みですが、今回の導入で使用箇所を新設しないでください。
+
+## 変更範囲
+
+animate-expo Skill導入時の変更範囲は、上記Skillファイルとこの `AGENTS.md` だけでした。各タスクの変更範囲は、現在のユーザー依頼と対象ファイルを基準に決め、未依頼のアプリコード、Expo設定、dependencies、lockfile、native treeを変更しないでください。
+
+
+## Phase 0〜1.5で確定した恒久アーキテクチャルール
+
+- React Navigationを、明示的な依頼なしにExpo Routerへ移行しない。
+- Navigation workaroundを削除・変更する前に、git historyと回帰テストを確認する。
+- API responseをScreenから直接長期保持しない。通信・parser・domain adapterの境界を通し、Screenは必要な表示状態だけを購読する。
+- `station number`をPhysical Stationのcanonical IDとして新規利用しない。Physical Station、Station Stop、Station Numberを分離する。
+- 列車番号だけを長期的なcanonical train identityとして新規利用しない。少なくともService Date、line、sourceを組み合わせる。
+- Native code、local module、target、config plugin、permission、entitlementの変更時は、OTA互換性を確認する。
+- Native変更を含む場合は、runtimeVersionと対象binary/buildの互換性を確認してからreleaseする。
+- 既存fallback APIを、代替経路と観測・回帰確認なしに削除しない。
+- pollingやsource切替のrequestは所有者を一つにし、in-flight重複、late response、unmount後のcommitを防ぐ。
+- 24時台・25時台などの鉄道時刻をJavaScript `Date`だけで表現しない。Calendar Date、Service Date、Wall Clock Time、Service Minuteを分離する。
+- release/runtimeの現在値は`app.json`、`eas.json`、package manifest/lockfile、EASの実測を確認する。現在のversionをskillの恒久ルールへ固定しない。
+- architecture/domainの契約変更は、`docs/architecture/`とpure fixture testを先に更新し、全データ移行を同じ変更へ混ぜない。
+
+## Network transport policy
+
+- 現在の通信baselineは標準の `fetch` です。Nitro Fetch用のdependency、runtime code、共通transport実装は現行treeにありません。
+- `react-native-nitro-fetch` / `react-native-nitro-modules` はSDK57で別branch・別binaryの検証を行いましたが、Nitro経路を有効にしたiOS/Android双方で起動時クラッシュを確認したため、7.2では採用しませんでした。
+- Nitro Fetchを明示的な新規検証依頼なしに再導入しないでください。過去の検証文書はactive roadmapではなく、historical experiment recordとして扱います。
+- これは永久禁止ではありません。library、Expo、React Native側の互換性が変わり、クラッシュ原因を隔離できる専用検証を行える場合に限り、標準fetchをbaselineとして別branch・別binaryで再評価します。
+
+## Git運用
+
+- ブランチを`develop`へ統合するときは、原則として明示的なマージコミットを作成する。`git merge --no-ff`を使用し、fast-forwardだけで統合しない。
+- マージ前に対象ブランチ、ベースコミット、作業ツリーの状態を確認し、既存の変更履歴をrebaseやsquashで書き換えない。
