docs: sync README and docs/ with current codebase

Surfaces features that landed after the last big docs pass: per-ride
history pages, Fast Lane wait times, outage shading on the today chart,
Tier-5 wait-time sampler, production-hardening pieces (rate limiter,
structured logger, env validation, graceful shutdown), and the new
rides + ride_wait_samples tables. Also corrects the weather-delay rule
to match the "open" vs "closing" gate now in rides.ts.

+Detailed docs live in the [`docs/`](docs/) folder:

+- [**Architecture**](docs/ARCHITECTURE.md) -- system design, data flow, caching layers, database schema, external APIs
+- [**Operations**](docs/OPERATIONS.md) -- deployment, monitoring, troubleshooting, backup, scheduler management
+- [**API Reference**](docs/API.md) -- complete backend endpoint documentation with request/response examples

+## Architecture
+
+The app runs as two containers:
+
+| Container | Port | Purpose |
+|-----------|------|---------|
+| **web** | 3000 | Next.js frontend — pure presentation layer, fetches all data from the backend API |
+| **backend** | 3001 | Hono API server — owns the SQLite database, runs tiered cron scheduling, handles all external API calls |
+
+The frontend makes no direct database or external API calls. All data flows through the backend.

 ## Tech Stack
 
 - **Next.js 15** — App Router, Server Components, standalone output
 - **Tailwind CSS v4** — `@theme {}` CSS variables, no config file
-- **SQLite** via `better-sqlite3` — persisted in `/app/data/parks.db`
+- **Hono** — lightweight TypeScript API framework for the backend
-- **Playwright** — one-time headless browser run to discover each park's internal API ID
+- **SQLite** via `better-sqlite3` — owned exclusively by the backend
-- **Six Flags CloudFront API** — `https://d18car1k0ff81h.cloudfront.net/operating-hours/park/{id}?date=YYYYMM`
+- **node-cron** — tiered scheduling (hourly → daily) for data freshness
-- **Queue-Times.com API** — live ride open/closed status and wait times, updated every 5 minutes

+2. **Schedule fallback (Six Flags API)** — when Queue-Times data is unavailable, the app falls back to the nearest upcoming date from the Six Flags schedule API as an approximation.
+
+### Fast Lane wait times
+
+A second wait number is fetched from Six Flags' `/wait-times/park/{apiId}` endpoint and joined onto each ride by name. The park page has a **Fast Lane** toggle (persisted in `localStorage.fastLaneMode`) that swaps the displayed wait between regular and Fast Lane. On the today chart, Fast Lane appears as a second line.
+
+### Per-ride history
+
+Click any ride name on a park page to open `/park/[id]/ride/[slug]` — a detail page with three tabs:
+
+- **Today** — 5-minute wait-time samples (regular + Fast Lane) with outage markers
+- **7 days** — daily average / max wait and uptime percentage
+- **30 days** — same aggregates over a longer window
+
+Samples are stored in the `ride_wait_samples` table by a Tier-5 cron job that runs every 5 minutes for parks currently within their operating window. Contiguous "ride closed during park hours" runs are shaded on the today chart with a `#N — Hh Mm` label.
 
 ### Roller Coaster Filter
 
-When live data is shown, a **Coasters only** toggle appears if roller coaster data has been populated for that park. Coaster lists are sourced from [RCDB](https://rcdb.com) and stored in `data/park-meta.json`. To populate them:
+When live data is shown, a **Coasters only** toggle filters to roller coasters. Coaster lists are hardcoded in `lib/coaster-data.ts`.
 
-1. Open `data/park-meta.json` and set `rcdb_id` for each park to the numeric RCDB park ID (visible in the URL: `https://rcdb.com/4529.htm` → `4529`).
+## Data Refresh
-2. Run `npm run scrape` — coaster lists are fetched from RCDB and stored in the JSON file. They refresh automatically every 30 days on subsequent scrapes.
+
+The backend runs a tiered scraping schedule via node-cron:
+
+| Tier | Schedule | Scope |
+|------|----------|-------|
+| 1 | Hourly (Mar–Dec) | Today's hours for all parks |
+| 2 | Every 6 hours | Current month for all parks |
+| 3 | Twice daily (3 AM, 3 PM) | Current + next month |
+| 4 | Daily at 3 AM | Full year (respects 72h staleness window) |
+| 5 | Every 5 minutes | Wait-time samples for all currently-open parks (writes `ride_wait_samples`) |
+
+Past dates are never overwritten. The hourly tier compares live data against the database before writing — unchanged data is skipped. Each tier has its own concurrency latch — if a tick is still running when the next would fire, the new tick is skipped and logged rather than stacked.
+
+A manual trigger is available via the backend API:
+
+```bash
+curl -X POST http://localhost:3001/api/scrape/trigger?scope=today

+The app ships as two Docker images:
-
-| Image | Tag | Purpose |
-|-------|-----|---------|
-| Next.js web server | `:web` | Reads DB, serves content. No scraping tools. |
-| Scraper + scheduler | `:scraper` | Nightly data refresh. No web server. |
-
-Images are built and pushed automatically by CI on every push to `main`.
-
-### First-time setup
-
-**1. Pull the images**
-
-```bash
-docker pull gitea.thewrightserver.net/josh/sixflagssupercalendar:web
-docker pull gitea.thewrightserver.net/josh/sixflagssupercalendar:scraper
-```
-
-**2. Discover park API IDs**
-
-This one-time step opens a headless browser for each park to find its internal Six Flags API ID. Run it against the scraper image so Playwright is available:
-
-```bash
-docker run --rm -v root_park_data:/app/data \
-  gitea.thewrightserver.net/josh/sixflagssupercalendar:scraper \
-  npm run discover
-```
-
-**3. Set RCDB IDs for the coaster filter**
-
-Open `data/park-meta.json` in the Docker volume and set `rcdb_id` for each park to the numeric ID from the RCDB URL (e.g. `https://rcdb.com/4529.htm` → `4529`). You can curl it directly from the repo:
-
-```bash
-curl -o /var/lib/docker/volumes/root_park_data/_data/park-meta.json \
-  https://gitea.thewrightserver.net/josh/SixFlagsSuperCalendar/raw/branch/main/data/park-meta.json
-```
-
-**4. Run the initial scrape**
-
-```bash
-docker run --rm -v root_park_data:/app/data \
-  gitea.thewrightserver.net/josh/sixflagssupercalendar:scraper \
-  npm run scrape
-```
-
-**5. Start services**
 
 ```bash
 docker compose up -d
 ```
 
-Both services start. The scraper runs nightly at 3 AM (container timezone, set via `TZ`).

-## Data Refresh
-
-The scraper skips any park + month already scraped within the staleness window (`PARK_HOURS_STALENESS_HOURS`, default 72h). Past dates are never overwritten — once a day occurs, the API stops returning data for it, so the record written when it was a future date is preserved forever. The nightly scraper handles refresh automatically.
-
-Roller coaster lists (from RCDB) are refreshed per `COASTER_STALENESS_HOURS` (default 720h = 30 days) for parks with a configured `rcdb_id`.

+None. All endpoints are public and unauthenticated. The scrape trigger endpoint is also unprotected -- restrict access at the network/proxy level if needed.
+
+## Rate limiting
+
+Every endpoint is gated by a fixed-window per-IP counter (`backend/src/middleware/rate-limit.ts`).
+
+| Header / Body | Value |
+|---------------|-------|
+| Limit | `RATE_LIMIT_PER_MIN` env var, default `60` requests/minute |
+| Window | 60 seconds, per client IP (resolved via `x-forwarded-for` → `x-real-ip` → socket address) |
+| Over-limit response | `429 Too Many Requests` |
+| Body | `{ "error": "Too many requests" }` |
+| Response header | `Retry-After: <seconds>` — how long until the window resets |
+
+Behind a reverse proxy, make sure `x-forwarded-for` is set or every request will appear to come from the proxy's own IP.

+
+Each ride is enriched from two sources: Queue-Times.com supplies `isOpen` and the base `waitMinutes`, then Six Flags' wait-times feed is joined by name to fill in `fastLaneMinutes` and `hasFastLane`. When both sources have a regular wait for the same ride, the Six Flags value wins (Queue-Times lags around park open). `fastLaneMinutes` is `null` when the ride is closed or has no Fast Lane line. `slug` is the URL-safe identifier used by `/api/parks/:id/rides/:slug`.
+
+**Response fields:**
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `parkId` | `string` | Echo of the park ID |
+| `today` | `string` | Current date (with 3 AM switchover) |
+| `parkOpenToday` | `boolean` | Whether the park has hours scheduled today |
+| `withinWindow` | `boolean` | Whether current time is within operating hours |
+| `isWeatherDelay` | `boolean` | Park is open but all rides are closed |
+| `liveRides` | `LiveRidesResult \| null` | Queue-Times live data (null if park has no mapping or is outside window) |
+| `scheduleFallback` | `RidesFetchResult \| null` | Six Flags schedule data (only populated when liveRides is null) |
+
+**Data priority:**
+1. If a Queue-Times mapping exists and the park is tracked, `liveRides` is populated.
+2. If outside the operating window, all rides in `liveRides` are forced to `isOpen: false`.
+3. If no live data is available, `scheduleFallback` is fetched from the Six Flags schedule API for the nearest open date.

+    fetchedAt: string;     // ISO timestamp of when we fetched from Queue-Times
+}
+```
+
+### RidesFetchResult
+
+Schedule-based ride data (fallback when live data is unavailable).
+
+```typescript
+interface RidesFetchResult {

+
+A single wait-time observation recorded by the Tier-5 sampler.
+
+```typescript
+interface DailySample {
+    recordedAt: string;                 // ISO 8601 UTC timestamp

+
+## Overview
+
+Thoosie Calendar is a full-stack web application that displays operating hours and live ride status for all 24 Six Flags Entertainment Group theme parks (including former Cedar Fair properties). The system scrapes schedule data from the Six Flags internal API on a tiered cron schedule, stores it in SQLite, and serves it through a Hono REST API. A Next.js frontend renders the data as a week-by-week calendar with live ride counts and park status indicators.
+
+The core architectural principle is **strict separation**: the frontend is a pure presentation layer that makes zero direct database or external API calls. All data flows through the backend.

+|-----------|------|------|
+| `web` | 3000 | Next.js standalone server -- SSR pages, static assets, ISR revalidation |
+| `backend` | 3001 | Hono API server -- REST endpoints, SQLite database, cron scheduler, external API calls |
+
+The web container reaches the backend via Docker internal networking (`http://backend:3001`). Both are independent images built from a single multi-stage Dockerfile.

+
+The `lib/` directory is the key shared boundary -- it is imported by both the frontend (via `@/lib/*` path alias) and the backend (via `@lib/*` alias resolving to `../lib/*`). This avoids duplicating types and park definitions across packages.
+
+---
+
+## Data Flow
+
+### Scraping Pipeline
+
+Data enters the system through the backend's cron-driven scraper:
+
+```
+node-cron trigger
+    |
+    v
+scraper.ts (orchestration)
+    |
+    ├── scrapeToday()         scrapeMonths()
+    |   for each park:        for each park × month:
+    |   fetchToday(apiId)     scrapeMonth(apiId, year, month)
+    |   500ms delay           1000ms delay
+    |   diff before write     transaction-wrapped bulk upsert
+    |                         staleness check (skip if fresh)
+    v
+sixflags.ts (API client)
+    |
+    v
+Six Flags CloudFront API
+    |  GET /operating-hours/park/{apiId}          (today, no date param)
+    |  GET /operating-hours/park/{apiId}?date=YYYYMM  (full month)
+    v
+parseApiDay() -> DayResult
+    |
+    v
+upsertDay() -> SQLite (park_days table)
+    |  INSERT ... ON CONFLICT DO UPDATE
+    |  WHERE park_days.date >= date('now')   <-- past-date protection
+    v
+Done
+```
+
+**Key behaviors:**
+
+- `scrapeToday()` uses a 500ms inter-park delay and diffs against the database before writing -- unchanged data is silently skipped.
+- `scrapeMonths()` uses a 1000ms delay, wraps each park-month's inserts in a SQLite transaction, and checks staleness before fetching. If a park-month was scraped within `PARK_HOURS_STALENESS_HOURS` (default 72h), it is skipped entirely.
+- The `WHERE date >= date('now')` clause in the upsert prevents overwriting historical data -- once a day passes, its record is frozen.
+- Rate limiting: on HTTP 429 or 503, the client retries with exponential backoff (30s, 60s, 120s). If a `Retry-After` header is present, it is respected (capped at 5 minutes). After 3 retries, a `RateLimitError` is thrown and logged; the scheduler continues to the next park.
+
+### Request Pipeline
+
+User-facing requests flow through Next.js server components to the backend API:
+
+```
+Browser request
+    |
+    v
+Next.js Server Component (app/page.tsx or app/park/[id]/page.tsx)
+    |
+    |  fetch(`${BACKEND_URL}/api/calendar/week?start=...`, { next: { revalidate: 120 } })
+    v
+Hono route handler (backend/src/routes/calendar.ts)
+    |
+    |  getDateRange(start, end)  -- SQLite query
+    |  + optional live merging (see below)
+    v
+JSON response -> React render -> HTML to browser
+```
+
+**ISR revalidation values:**
+
+| Page | Endpoint | Revalidate |
+|------|----------|------------|
+| Home (week view) | `/api/calendar/week` | 120s |
+| Park detail (month) | `/api/calendar/:parkId/month` | 300s |
+| Park detail (rides) | `/api/parks/:id/rides` | 60s |
+
+### Live Data Merging
+
+When the requested week includes today, the `/api/calendar/week` route enhances database data with live information:
+
+1. **Live today hours** -- For each park, calls `fetchToday(apiId)` to get the current day's schedule directly from the Six Flags API. Results are cached in `todayCache` (5-min TTL). A `_checked` sentinel key prevents re-fetching parks that returned `null`.
+
+2. **Live ride counts** -- For each park that is currently within its operating window (determined by `isWithinOperatingWindow()`), fetches live ride data from Queue-Times.com via `fetchLiveRides()`. Counts open rides and open coasters. Results cached in `ridesCache` (5-min TTL).
+
+3. **Status detection:**
+   - **Open**: Within the scheduled open-to-close window. `getOperatingStatus()` returns `"open"`.
+   - **Closing**: Current time is past the scheduled close but within a 1-hour wind-down buffer. `getOperatingStatus()` returns `"closing"`.
+   - **Weather delay**: `getOperatingStatus()` is `"open"` _and_ every reported ride has `isOpen: false`. Indicated with a blue badge. The badge is intentionally suppressed during the `"closing"` wind-down — all-rides-closed near close is normal end-of-day behavior, not weather. Logic lives at [backend/src/routes/rides.ts:96-100](../backend/src/routes/rides.ts) and [backend/src/routes/calendar.ts](../backend/src/routes/calendar.ts).
+
+The 3 AM switchover in `getTodayLocal()` prevents the calendar from flipping to the next day at midnight -- before 3 AM local time, the system still considers it "yesterday", since park visitors may still be out.
+
+---
+
+## Caching Architecture
+
+The system uses three layers of caching, each serving a different purpose:
+
+```
+ Layer 1: Next.js ISR              Layer 2: Backend In-Memory         Layer 3: Database Staleness
+ (serves stale while revalidating) (prevents redundant API calls)     (controls scrape frequency)
+ ┌───────────────────────────────┐ ┌───────────────────────────────┐  ┌───────────────────────────────┐
+ │ Cache-Control response headers│ │ TtlCache<T> (5 min TTL)       │  │ isMonthScraped() query        │
+ │ + Next.js fetch revalidate    │ │                               │  │ MAX(scraped_at) vs staleness  │
+ │                               │ │ todayCache:    routes/calendar│  │ threshold (default 72h)       │
+ │ week:  120s / 300s SWR        │ │   (live park hours per park)  │  │                               │
+ │ month: 300s / 600s SWR        │ │ liveRidesCache, fastLaneCache:│  │ Past months auto-skipped      │
+ │ rides: 60s  / 120s SWR        │ │   services/live-cache.ts —    │  │ "force" scope bypasses check  │
+ │ parks: 3600s                  │ │   shared by rides routes +    │  │                               │
+ │                               │ │   the Tier-5 sampler          │  │                               │
+ └───────────────────────────────┘ └───────────────────────────────┘  └───────────────────────────────┘
+```
+
+**Live-page Data Cache bypass.** The park detail page (`app/park/[id]/page.tsx`) and ride detail page (`app/park/[id]/ride/[slug]/page.tsx`) fetch their live ride data with `cache: "no-store"` via [`apiFetch`](../lib/api.ts) (`{ noStore: true }`). Earlier revisions used Next.js ISR for these too, but the Data Cache served stale ride state after idle periods — navigation back to a park would show ride statuses from hours ago. Backend HTTP cache headers still allow the upstream Hono server to return cached responses for 60s, so this is a "skip the Next.js Data Cache" change, not a "skip all caching" change. The home calendar page keeps its ISR revalidation since its data is intrinsically slower-moving.
+
+**Per-route HTTP cache headers:**
+
+| Endpoint | `max-age` | `stale-while-revalidate` |
+|----------|-----------|--------------------------|
+| `/api/calendar/week` | 120s | 300s |
+| `/api/calendar/:parkId/month` | 300s | 600s |
+| `/api/parks` | 3600s | -- |
+| `/api/parks/:id` | 3600s | -- |
+| `/api/parks/:id/rides` | 60s | 120s |
+| `/api/parks/:id/rides/:slug` | 60s | 120s |
+
+---
+
+## Database
+
+### Schema
+
+The database has three tables: `park_days` (calendar hours), `rides` (per-ride metadata), and `ride_wait_samples` (time-series wait data).
+
+```sql
+-- Park operating hours, keyed by park and date.
+CREATE TABLE IF NOT EXISTS park_days (
+    park_id      TEXT    NOT NULL,   -- matches Park.id from lib/parks.ts (e.g. "cedarpoint")
+    date         TEXT    NOT NULL,   -- ISO date: YYYY-MM-DD
+    is_open      INTEGER NOT NULL DEFAULT 0,  -- 0 = closed, 1 = open
+    hours_label  TEXT,               -- e.g. "10am - 6pm", null when closed
+    special_type TEXT,               -- "passholder_preview" or null
+    scraped_at   TEXT    NOT NULL,   -- ISO timestamp of when this row was written
+    PRIMARY KEY (park_id, date)
+);
+
+-- Per-ride canonical record. PK is (park_id, qt_ride_id) so ride renames
+-- don't fragment history — the slug just provides pretty URLs.
+CREATE TABLE IF NOT EXISTS rides (
+    park_id        TEXT    NOT NULL,
+    qt_ride_id     INTEGER NOT NULL,   -- Queue-Times ride ID (stable upstream)
+    slug           TEXT    NOT NULL,   -- URL slug (rebuilt if name changes)
+    name           TEXT    NOT NULL,   -- Display name as last seen
+    is_coaster     INTEGER NOT NULL DEFAULT 0,
+    has_fast_lane  INTEGER NOT NULL DEFAULT 0,
+    first_seen     TEXT    NOT NULL,
+    last_seen      TEXT    NOT NULL,
+    PRIMARY KEY (park_id, qt_ride_id)
+);
+CREATE UNIQUE INDEX IF NOT EXISTS idx_rides_slug ON rides (park_id, slug);
+
+-- Time-series wait samples written by Tier-5 every 5 minutes for currently
+-- open parks. `recorded_at` is UTC; `local_date` / `local_time` are bucketed
+-- in the park's IANA timezone at insert time so reads are pure SQL and DST-safe.
+CREATE TABLE IF NOT EXISTS ride_wait_samples (
+    park_id           TEXT    NOT NULL,
+    qt_ride_id        INTEGER NOT NULL,
+    recorded_at       TEXT    NOT NULL,   -- ISO UTC
+    local_date        TEXT    NOT NULL,   -- YYYY-MM-DD in park tz
+    local_time        TEXT    NOT NULL,   -- HH:MM in park tz
+    is_open           INTEGER NOT NULL,
+    wait_minutes      INTEGER,            -- Regular line wait
+    fast_lane_minutes INTEGER,            -- Six Flags Fast Lane wait, if known
+    PRIMARY KEY (park_id, qt_ride_id, recorded_at)
+);
+```
+
+- **Composite primary keys** ensure one row per logical unit (per park-day, per ride, per sample) and support efficient queries without secondary indexes. `idx_rides_slug` lets the ride detail route resolve a `slug` to a `qt_ride_id` in one lookup.
+- **WAL mode** (`PRAGMA journal_mode = WAL`) enables concurrent reads while the scraper writes.
+- **Migration strategy**: New columns are added via `ALTER TABLE ... ADD COLUMN` wrapped in try/catch. If the column already exists, the error is silently caught. This allows the schema to evolve without a migration framework.
+- **Sample volume**: Tier-5 writes one row per open ride every 5 minutes during park hours. A park with 50 rides operating for 10 hours generates ~6,000 sample rows/day. `INSERT OR IGNORE` on the PK makes the sampler idempotent across retries.
+
+### Key Queries
+
+| Function | Purpose |
+|----------|---------|
+| `upsertDay()` | Insert or update a day. Uses `ON CONFLICT DO UPDATE` with `WHERE date >= date('now')` to protect historical records. |
+| `getDateRange(start, end)` | Returns all parks' data for a date range. Powers the week calendar. |
+| `getParkMonthData(parkId, year, month)` | Returns one park's data for a month. Uses `LIKE` prefix matching on date. |
+| `getDayData(parkId, date)` | Returns a single day for comparison during `scrapeToday()`. |
+| `getParkDayCount()` | Total rows in `park_days`. Drives the startup-scrape-when-empty check. |
+| `isMonthScraped(parkId, year, month, staleAfterMs)` | Checks if `MAX(scraped_at)` for a park-month is within the staleness threshold. Past months always return `true` (never re-scraped). |
+| `upsertRide()` | Insert or update a row in `rides`; bumps `last_seen` on every observation. |
+| `getRideBySlug(parkId, slug)` | Resolves a URL slug back to a canonical ride record via `idx_rides_slug`. |
+| `insertSample()` | `INSERT OR IGNORE` a sample into `ride_wait_samples` — idempotent on retries. |
+| `getRideSamplesForDay()` | Returns all samples for one ride on one local date (powers the Today chart). |
+| `getRideDailyAggregates()` | Per-day avg/max wait, avg/max Fast Lane, uptime %, and sample count over a window (powers the 7d / 30d charts). |
+| `countRideDays()` | Number of distinct `local_date` values for a ride in a window — used to decide whether 7d/30d tabs have enough data to render. |
+| `transact(fn)` | Wraps a function in a SQLite transaction for atomicity. |
+
+### Storage
+
+- **Location**: `backend/data/parks.db` (or `/app/backend/data/parks.db` in Docker)
+- **WAL journal files**: `parks.db-wal` and `parks.db-shm` accompany the main database
+- **Size**:
+  - `park_days`: ~8,000-9,000 rows for a full year of 24 parks
+  - `rides`: ~1,000-1,500 rows total (a few dozen per park)
+  - `ride_wait_samples`: grows daily during operating season; expect tens of thousands of rows per active day. Historical samples are retained — no automatic pruning is configured.
+- **Not committed to git**: Listed in `.gitignore`
+- **Auto-created**: The database and `data/` directory are created on first backend startup

+
+## External API Contracts
+
+### Six Flags CloudFront API
+
+The primary data source for park operating hours and ride schedules.
+
+| Property | Value |
+|----------|-------|
+| Base URL | `https://d18car1k0ff81h.cloudfront.net/operating-hours/park/{apiId}` |
+| Auth | None (public, but uses spoofed browser headers) |
+| Timeout | 15 seconds (`AbortSignal.timeout`) |
+| Rate limiting | 429/503 with exponential backoff |
+
+**Two call patterns:**
+
+1. **Today** (no date param): `GET /operating-hours/park/{apiId}` -- returns a single day.
+2. **Full month**: `GET /operating-hours/park/{apiId}?date=YYYYMM` -- returns all days in the month.
+
+**Response shape:**
+
+```typescript
+interface ApiResponse {
+    parkId: number;
+    parkAbbreviation: string;
+    parkName: string;
+    dates: ApiDay[];
+}
+
+interface ApiDay {
+    date: string;            // "MM/DD/YYYY"
+    isParkClosed: boolean;
+    events?: ApiEvent[];     // passholder previews, special events
+    operatings?: ApiOperating[];  // operating hours by type ("Park", "Special Event")
+    venues?: ApiVenue[];     // ride-level detail hours
+}
+```
+
+**Parsing logic (`parseApiDay`):**
+- Finds the "Park" operating type (falls back to first available)
+- Extracts `timeFrom`/`timeTo` from the first item and formats to 12-hour (`"10am - 6pm"`)
+- Detects passholder previews via `events[].extEventName` containing "passholder preview"
+- Handles buyouts: if `isBuyout` is true and it's not a passholder preview, the park is considered closed
+- Returns `{ date, isOpen, hoursLabel, specialType }`
+
+### Six Flags Wait-Times API
+
+Powers the Fast Lane wait number shown alongside the regular wait. Used by `lib/scrapers/sixflags-waittimes.ts` (`fetchFastLaneWaits`, `lookupFastLane`) and joined onto the Queue-Times rides by fuzzy name match.
+
+| Property | Value |
+|----------|-------|
+| URL | `https://d18car1k0ff81h.cloudfront.net/wait-times/park/{apiId}` (sibling of the operating-hours endpoint) |
+| Auth | None (spoofed browser headers, same as the operating-hours client) |
+| Timeout | 10 seconds |
+| Per-ride fields | `regularMinutes`, `fastLaneMinutes`, `hasFastLane` (`lookupFastLane()` return shape) |
+| Error handling | Returns `null` on any failure; the route falls back to Queue-Times' regular wait |
+| Backend cache | `fastLaneCache` (5-min TTL, in `services/live-cache.ts`) |
+
+**Why two sources?** Queue-Times wait values lag at park open by ~10-15 minutes (parks haven't reported yet). The Six Flags wait-times feed updates earlier. When both sources have a wait for the same ride, the route prefers the Six Flags regular wait; Queue-Times remains the source of truth for `isOpen`. The Fast Lane number has no Queue-Times equivalent.
+
+### Queue-Times.com API
+
+Provides live ride open/closed status and wait times during park operating hours.
+
+| Property | Value |
+|----------|-------|
+| URL | `https://queue-times.com/parks/{queueTimesId}/queue_times.json` |
+| Auth | None (public) |
+| Timeout | 10 seconds (`AbortSignal.timeout`) |
+| Update frequency | ~5 minutes during park operation |
+| Attribution | Required: "Powered by Queue-Times.com" |
+| Error handling | Returns `null` on any failure (no exceptions) |
+
+**Response shape:**
+
+```typescript
+interface QTResponse {
+    lands: Array<{
+        id: number;
+        name: string;
+        rides: Array<{
+            id: number;
+            name: string;
+            is_open: boolean;
+            wait_time: number;
+            last_updated: string;  // ISO 8601
+        }>;
+    }>;
+}
+```
+
+### Coaster Classification
+
+Rides are classified as roller coasters using static data from the Roller Coaster Database (RCDB), stored in `lib/coaster-data.ts` as `Set<string>` per park. Matching uses three strategies (in order):
+
+1. **Exact normalized match** -- both names are lowercased, stripped of trademark symbols, possessives, and leading "THE".
+2. **Compact match** -- spaces are removed from both names (catches "BAT GIRL" vs "Batgirl").
+3. **Prefix match** -- the shorter name is a prefix of the longer (min 5 chars), unless the next word after the prefix is a conjunction ("y", "and", "&"), which signals a different ride rather than a subtitle.
+

+
+## Frontend Architecture
+
+### Server vs Client Components
+
+| Component | Type | Role |
+|-----------|------|------|
+| `app/page.tsx` | Server | Fetches week data from backend, passes to HomePageClient |
+| `app/park/[id]/page.tsx` | Server | Fetches month + rides data in parallel |
+| `app/park/[id]/ride/[slug]/page.tsx` | Server | Fetches ride detail + today/7d/30d history in one call |
+| `HomePageClient` | **Client** | State management, auto-refresh, keyboard nav, localStorage |
+| `WeekCalendar` | Server | Desktop 7-column table layout |
+| `MobileCardList` | Server | Mobile card layout |
+| `ParkCard` | Server | Individual park card for mobile |
+| `ParkMonthCalendar` | Server | Month calendar grid |
+| `LiveRidePanel` | **Client** | Live ride list with coaster filter + Fast Lane toggle |
+| `WeekNav` | **Client** | Week navigation with arrow buttons |
+| `Legend` | Server | Status color legend |
+| `EmptyState` | Server | Empty database message |
+| `BackToCalendarLink` | **Client** | "Back" link using localStorage for last week |
+| `charts/WaitTimeTodayChart` | **Client** | Today's 5-min wait samples + outage shading (Recharts) |
+| `charts/WeeklyStatsChart` | **Client** | 7d / 30d daily aggregates chart (Recharts) |
+| `charts/UptimePill` | **Client** | Compact uptime % badge |
+
+### Component Hierarchy
+
+```
+page.tsx (Server)
+  └── HomePageClient (Client)
+        ├── WeekNav (Client) ............ arrow buttons, keyboard listener
+        ├── Legend (Server) ............. color key
+        ├── MobileCardList (Server) ..... visible below lg breakpoint
+        │     └── ParkCard (Server)
+        └── WeekCalendar (Server) ....... visible at lg+ breakpoint
+
+park/[id]/page.tsx (Server)
+  ├── BackToCalendarLink (Client)
+  ├── ParkMonthCalendar (Server)
+  └── LiveRidePanel (Client) ........... or RideList (Server, inline)
+
+park/[id]/ride/[slug]/page.tsx (Server)
+  ├── BackToCalendarLink (Client)
+  ├── UptimePill (Client)
+  ├── WaitTimeTodayChart (Client) ...... Today tab
+  └── WeeklyStatsChart (Client) ........ 7d / 30d tabs
+```
+
+### Client-Side Refresh
+
+`HomePageClient` manages three refresh mechanisms when viewing the current week:
+
+1. **Periodic refresh**: `setInterval(router.refresh, 120_000)` -- re-fetches data every 2 minutes via Next.js router refresh (no full page reload).
+2. **Opening-time refresh**: For each park open today, calculates milliseconds until its opening time using `msUntilLocalTime()` (timezone-aware). Schedules `router.refresh()` at opening and again 30 seconds later (to pick up ride counts after Queue-Times starts reporting).
+3. **Keyboard navigation**: Left/right arrow keys navigate between weeks (via `WeekNav` component).
+
+### Cookies
+
+| Name | Purpose |
+|------|---------|
+| `tcWeek` | Selected week start date (`YYYY-MM-DD`). Set by `WeekNav` and read server-side by `app/page.tsx`, so the home page renders the right week without polluting the URL. |
+
+### localStorage
+
+| Key | Purpose |
+|-----|---------|
+| `coasterMode` | Persists the "Coasters only" toggle state across sessions |
+| `fastLaneMode` | Persists the Fast Lane wait toggle on the park page |
+
+### Responsive Design
+
+The `lg:` Tailwind breakpoint (1024px) switches between two layouts:
+- **Below `lg`**: `MobileCardList` -- parks shown as cards with daily status indicators
+- **At `lg`+**: `WeekCalendar` -- full 7-column table with region groupings
+
+### Loading State
+
+`app/loading.tsx` renders a skeleton UI with a CSS pulse animation, providing immediate visual feedback while server components stream.
+
+---
+
+## Park Data Model
+
+All 24 parks are defined in `lib/parks.ts` as a `PARKS` array with the following interface:
+
+```typescript
+interface Park {
+    id: string;          // Unique identifier (e.g. "cedarpoint", "greatadventure")
+    apiId: number;       // Six Flags CloudFront API park ID
+    name: string;        // Full display name
+    shortName: string;   // Abbreviated name for logs and compact UI
+    chain: string;       // "sixflags" for all parks
+    slug: string;        // URL-safe slug (matches sixflags.com paths)
+    region: string;      // One of 5 geographic regions
+    location: {
+        lat: number;
+        lng: number;
+        city: string;
+        state: string;
+    };
+    timezone: string;    // IANA timezone (e.g. "America/New_York")
+    website: string;     // Park website URL
+}
+```
+
+**Regions:**
+- Northeast (6 parks): Great Adventure, New England, Great Escape, Darien Lake, Dorney Park, Canada's Wonderland
+- Southeast (3 parks): Over Georgia, Carowinds, Kings Dominion
+- Midwest (7 parks): Great America (IL), St. Louis, Cedar Point, Kings Island, Valleyfair, Worlds of Fun, Michigan's Adventure
+- Texas & South (3 parks): Over Texas, Fiesta Texas, Frontier City
+- West & International (5 parks): Magic Mountain, Discovery Kingdom, Knott's Berry Farm, California's Great America, Mexico
+
+**Lookup utilities:**
+- `PARK_MAP`: `Map<string, Park>` for O(1) lookup by `id`
+- `groupByRegion(parks)`: Groups a park array into `{ region, parks }` tuples
+- `QUEUE_TIMES_IDS`: Maps park `id` to Queue-Times.com park ID (separate file)
+- `getCoasterSet(parkId)`: Returns the `Set<string>` of normalized coaster names for a park
+
+---
+
+## Security
+
+| Measure | Implementation |
+|---------|----------------|
+| Content Security Policy | Defined in `next.config.ts` -- restricts scripts, styles, images, connections |
+| X-Frame-Options | `DENY` -- prevents embedding in iframes |
+| X-Content-Type-Options | `nosniff` -- prevents MIME type sniffing |
+| Referrer-Policy | `strict-origin-when-cross-origin` |
+| Permissions-Policy | Disables geolocation, microphone, camera |
+| Non-root containers | Both Docker images run as `nextjs` user (UID 1001) |
+| Backend-owned data | Frontend never contacts external APIs or the database directly |
+| CORS | Backend enables CORS middleware (currently unrestricted) |
+| Per-IP rate limit | `RATE_LIMIT_PER_MIN` (default 60) — fixed-window per-IP counter in `backend/src/middleware/rate-limit.ts`. Honours `x-forwarded-for`/`x-real-ip` so a reverse proxy doesn't collapse every client to one bucket. Over-limit requests return `429` with a `Retry-After` header. |
+| Env validation | `backend/src/config.ts` parses + validates env vars at startup; misconfiguration fails fast rather than surfacing in a request handler. |
+| Graceful shutdown | Backend listens for `SIGTERM`/`SIGINT`, closes the HTTP server and SQLite handle before exiting (force-exit timeout as a safety net). |
+| No secrets in frontend | `BACKEND_URL` is an internal Docker network address, not a secret |

+# Development
+
+> See also: [Architecture](ARCHITECTURE.md) | [Operations](OPERATIONS.md) | [API Reference](API.md)
+
+## Prerequisites
+
+- **Node.js 22+** and **npm**
+- No database tools needed (SQLite is auto-created by the backend)
+- No Docker needed for local development
+
+---
+
+## Setup
+
+```bash
+# Clone the repository
+git clone <repo-url>
+cd ThoosieCalendar
+
+# Install frontend dependencies
+npm install
+
+# Install backend dependencies
+cd backend && npm install && cd ..
+```
+
+---
+
+## Running Locally
+
+The project requires two terminals -- one for the backend, one for the frontend.
+
+### Terminal 1: Backend
+
+```bash
+cd backend
+npm run dev
+```
+
+This starts the Hono API server on port 3001 using `tsx` (TypeScript runtime with watch mode). On first run:
+- Creates an empty SQLite database at `backend/data/parks.db`
+- Registers the four-tier cron scheduler
+- The schedulers will populate data automatically over time, or you can trigger a manual scrape immediately:
+
+```bash
+curl -X POST http://localhost:3001/api/scrape/trigger?scope=full
+```
+
+### Terminal 2: Frontend
+
+```bash
+npm run dev
+```
+
+This starts the Next.js dev server on port 3000 with hot reload. Open [http://localhost:3000](http://localhost:3000).
+
+**Navigation:**
+- Use the `←` / `→` buttons (or arrow keys) to navigate weeks; the selected week persists across visits via the `tcWeek` cookie
+- Click any park name to open its detail page with month calendar and ride status
+
+---
+
+## Project Structure Walkthrough
+
+### `app/` -- Next.js Pages
+
+Three routes:
+- `/` (`app/page.tsx`) -- Home page. Server component that fetches week data from the backend and passes everything to `HomePageClient`.
+- `/park/[id]` (`app/park/[id]/page.tsx`) -- Park detail page. Fetches month calendar and live rides in parallel via `Promise.all`. Live rides use `apiFetch({ noStore: true })` to bypass the Next.js Data Cache.
+- `/park/[id]/ride/[slug]` (`app/park/[id]/ride/[slug]/page.tsx`) -- Per-ride detail page with Today / 7d / 30d wait-time history. All three tabs render from a single backend response (no client-side range fetches).
+
+Top-level boundaries: `app/error.tsx` (root error UI), `app/not-found.tsx`, `app/park/[id]/error.tsx`, and `app/loading.tsx` (streaming skeleton).
+
+### `components/` -- React Components
+
+| Component | Type | Purpose |
+|-----------|------|---------|
+| `HomePageClient` | Client | Top-level state: coaster filter, auto-refresh, keyboard nav |
+| `WeekCalendar` | Server | Desktop 7-column table with region groupings |
+| `MobileCardList` | Server | Mobile card layout (below `lg` breakpoint) |
+| `ParkCard` | Server | Individual park card for mobile |
+| `ParkMonthCalendar` | Server | Month grid for park detail page |
+| `LiveRidePanel` | Client | Live ride list with coaster toggle, Fast Lane toggle, wait times |
+| `WeekNav` | Client | Week navigation arrows |
+| `Legend` | Server | Color legend for status indicators |
+| `EmptyState` | Server | Empty database message |
+| `BackToCalendarLink` | Client | Back link using localStorage for last week |
+| `charts/WaitTimeTodayChart` | Client | Today's 5-min wait samples with outage shading (Recharts) |
+| `charts/WeeklyStatsChart` | Client | 7d / 30d daily aggregate chart (Recharts) |
+| `charts/UptimePill` | Client | Compact uptime % badge |
+

+| `scrapers/types.ts` | `Park`, `DayStatus`, `MonthCalendar`, `ScraperAdapter` interfaces |
+
+### `backend/src/` -- Hono API Server
+
+| File | Purpose |
+|------|---------|
+| `index.ts` | Entry point -- middleware (request log, CORS, rate limit), route registration, DB init, scheduler start, graceful shutdown |
+| `config.ts` | Env-validated config object (`PORT`, `RATE_LIMIT_PER_MIN`, `PARK_HOURS_STALENESS_HOURS`, `NODE_ENV`). Fails fast on bad input. |
+| `log.ts` | Structured logger -- emits `[ISO] [LEVEL] [tag] msg key=value` lines. No external dep. |
+| `db/index.ts` | SQLite connection singleton, schema for `park_days` / `rides` / `ride_wait_samples`, WAL mode |

+| `services/scheduler.ts` | Five-tier cron registration with per-tier `withLatch` concurrency guards; startup-scrape-when-empty check |
+| `services/scraper.ts` | Scraping orchestration -- `scrapeToday()`, `scrapeMonths()`, `scrapeFullYear()` |
+| `services/wait-sampler.ts` | Tier-5 5-minute sampler -- joins Queue-Times + Fast Lane, writes `ride_wait_samples`, skips weather-delayed parks |
+| `services/live-cache.ts` | Shared `TtlCache<T>` instances (`liveRidesCache`, `fastLaneCache`) so the rides route, the ride-history route, and the Tier-5 sampler share warmed upstream data |
+| `services/cache.ts` | Generic `TtlCache<T>` class with configurable TTL |
+
+---
+
+## Adding a New Park
+
+Adding a park requires changes to three files. The park will be automatically picked up by the scheduler, the API, and the frontend.
+
+### 1. `lib/parks.ts`
+
+Add an entry to the `PARKS` array:
+
+```typescript
+{
+    id: "newpark",           // URL-safe unique identifier
+    apiId: 123,              // Six Flags CloudFront API park ID
+    name: "Six Flags New Park",
+    shortName: "New Park",
+    chain: "sixflags",
+    slug: "newpark",         // Should match sixflags.com URL path
+    region: "Midwest",      // One of: Northeast, Southeast, Midwest, Texas & South, West & International
+    location: {
+        lat: 40.0,
+        lng: -80.0,
+        city: "Anytown",
+        state: "OH",
+    },
+    timezone: "America/New_York",  // IANA timezone
+    website: "https://www.sixflags.com",
+},
+```
+
+**Finding the API ID:** Use the debug script or inspect network requests on the Six Flags website. The `apiId` is the numeric park identifier in the CloudFront API URL.
+
+### 2. `lib/queue-times-map.ts`
+
+Add the Queue-Times.com park ID mapping:
+
+```typescript
+export const QUEUE_TIMES_IDS: Record<string, number> = {
+    // ... existing mappings
+    newpark: 456,  // Queue-Times park ID
+};
+```
+
+**Finding the Queue-Times ID:** Browse [queue-times.com](https://queue-times.com), navigate to the park, and note the numeric ID in the URL.
+
+### 3. `lib/coaster-data.ts`
+
+Add the coaster name set:
+
+```typescript
+export function getCoasterSet(parkId: string): Set<string> | null {
+    // ... existing cases
+    case "newpark":
+        return new Set([
+            normalizeForMatch("Coaster Name One"),
+            normalizeForMatch("Coaster Name Two"),
+        ]);
+}
+```
+
+**Finding coaster names:** Look up the park on [RCDB (Roller Coaster Database)](https://rcdb.com). List all operating roller coasters. Names should be the official RCDB names before normalization.
+
+---
+
+## Debug Script
+
+Inspect raw API data and parsed output for any park and date:
+
+```bash
+npm run debug -- --park <parkId> --date <YYYY-MM-DD>
+```
+
+**Example:**
+
+```bash
+npm run debug -- --park kingsisland --date 2026-06-15
+```
+
+This fetches the raw Six Flags API response for the park and date, displays the parsed result, and saves the raw JSON to the `debug/` directory for inspection. Useful for:
+- Investigating API response format changes
+- Debugging parsing issues for specific parks/dates
+- Verifying that a park's `apiId` is correct
+
+---
+
+## Testing
+
+Frontend and backend each have their own test suite, both using the Node built-in test runner.
+
+### Frontend tests
+
+```bash
+npm test
+```
+
+Test files live in `tests/`:
+
+| File | Coverage |
+|------|----------|
+| `tests/coaster-matching.test.ts` | `isCoasterMatch()` — exact, prefix, compact, conjunction rejection |
+| `tests/fast-lane-matching.test.ts` | `lookupFastLane()` — name normalization and Fast Lane join logic |
+| `tests/outage-detection.test.ts` | `computeOutages()` — contiguous-closed-run detection for the today chart |
+| `tests/ride-slug.test.ts` | `slugifyRideName()` — URL slug generation and stability |
+| `tests/timezone-bucketing.test.ts` | `formatLocalDate()` / `formatLocalTime()` — DST-safe park-tz bucketing |
+
+### Backend tests
+
+```bash
+cd backend && npm test
+```
+
+Test files live in `backend/tests/`:
+
+| File | Coverage |
+|------|----------|
+| `backend/tests/wait-aggregation.test.ts` | SQL aggregation in `getRideDailyAggregates()` — averages, max, uptime, sample count |
+
+---
+
+## Code Conventions
+
+### TypeScript
+
+- **Strict mode** enabled in both `tsconfig.json` files
+- Frontend uses `bundler` module resolution with `@/*` path alias
+- Backend uses `CommonJS` modules with `@lib/*` alias resolving to `../lib/*`
+
+### Styling
+
+- **Inline styles** via `style={{}}` props for most component styling
+- **Tailwind CSS v4** for responsive utilities (`hidden lg:block`, `sm:flex`, `px-4 sm:px-6`)
+- Theme defined via `@theme {}` block and CSS custom properties in `app/globals.css`
+- No CSS modules, no styled-components, no component library
+
+### Code Organization
+
+- Shared types and utilities live in `lib/` and are imported by both frontend and backend
+- No component library -- all UI is built from scratch
+- Backend uses `tsx` for runtime TypeScript execution (no build step in development)

+## Building Docker Images Locally
+
+```bash
+# Build the web image
+docker build --target web -t thoosiecalendar:web .
+
+# Build the backend image
+docker build --target backend -t thoosiecalendar:backend .
+
+# Run locally with Docker Compose
+docker compose up -d
+
+# Or run individual containers
+docker run -d -p 3001:3001 -v park_data:/app/backend/data -e TZ=America/New_York thoosiecalendar:backend
+docker run -d -p 3000:3000 -e BACKEND_URL=http://host.docker.internal:3001 thoosiecalendar:web
+```
+
+When running individual containers outside of Docker Compose, use `host.docker.internal` instead of `backend` for the `BACKEND_URL`, since Docker's internal DNS won't resolve service names without Compose.

+
+## Deployment Overview
+
+The application runs as two Docker containers:
+
+| Container | Port | Role |
+|-----------|------|------|
+| `web` | 3000 | Next.js frontend (stateless, no database) |
+| `backend` | 3001 | Hono API server (owns SQLite database, runs cron scheduler) |
+
+**Infrastructure requirements:**
+- Docker host with Docker Compose
+- Container registry (Gitea, Docker Hub, or any OCI-compatible registry)
+- Outbound HTTPS access to `d18car1k0ff81h.cloudfront.net` (Six Flags API) and `queue-times.com` (live ride data)
+- A reverse proxy (Traefik, nginx, Caddy, etc.) is expected to sit in front for TLS termination and domain routing, but is not included in this repository
+
+See [Architecture](ARCHITECTURE.md) for detailed system design.
+
+---
+
+## Docker Images
+
+### Multi-Stage Build
+
+The project uses a single `Dockerfile` with four stages producing two final images:
+
+```
+  builder           backend-deps
+  (Next.js build)   (native modules)
+      |                   |
+      v                   v
+    web               backend
+  (final)             (final)
+```
+
+| Stage | Base | Purpose |
+|-------|------|---------|
+| `builder` | `node:22-bookworm-slim` | `npm ci` + `npm run build` -- produces Next.js standalone output |
+| `backend-deps` | `node:22-bookworm-slim` | Installs `python3`, `make`, `g++` for `better-sqlite3` native compilation, then `npm ci` |
+| `web` (final) | `node:22-bookworm-slim` | Copies standalone output from `builder`. Non-root user. ~150MB. |
+| `backend` (final) | `node:22-bookworm-slim` | Copies `node_modules` from `backend-deps` + source code. Volume for SQLite. Non-root user. ~200MB. |
+

+
+### Building Locally
+
+```bash
+# Build web image
+docker build --target web -t thoosiecalendar:web .
+
+# Build backend image
+docker build --target backend -t thoosiecalendar:backend .
+```
+
+---
+
+## Docker Compose
+
+The production `docker-compose.yml`:
+
+```yaml
+services:
+  web:
+    image: gitea.thewrightserver.net/josh/thoosiecalendar:web
+    ports:
+      - "3000:3000"
+    environment:
+      - NODE_ENV=production
+      - BACKEND_URL=http://backend:3001    # Docker internal networking
+      - TZ=America/New_York
+    restart: unless-stopped
+
+  backend:
+    image: gitea.thewrightserver.net/josh/thoosiecalendar:backend
+    ports:
+      - "3001:3001"
+    volumes:
+      - park_data:/app/backend/data         # SQLite database persistence
+    environment:
+      - NODE_ENV=production
+      - TZ=America/New_York                # Timezone for cron schedules
+      - PARK_HOURS_STALENESS_HOURS=72      # Hours before re-fetching park data
+    restart: unless-stopped
+
+volumes:
+  park_data:                               # Named volume for database files
+```
+
+**Networking:** The `web` container reaches the backend via Docker's internal DNS at `http://backend:3001`. The backend port is also exposed to the host for manual API access during troubleshooting.
+
+---
+
+## Environment Variables
+
+### Web Container
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `BACKEND_URL` | `http://localhost:3001` | Backend API base URL. Set to `http://backend:3001` in Docker Compose for internal networking. |
+| `NODE_ENV` | -- | Set to `production` in Docker. |
+| `NEXT_TELEMETRY_DISABLED` | `1` | Disables Next.js telemetry (set in Dockerfile). |
+| `PORT` | `3000` | Server listen port (set in Dockerfile). |
+| `HOSTNAME` | `0.0.0.0` | Bind address (set in Dockerfile to allow external access). |
+
+### Backend Container
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `TZ` | `UTC` | Process timezone. Controls when cron jobs fire. Set to `America/New_York` in production so schedules align with US Eastern parks. |
+| `PARK_HOURS_STALENESS_HOURS` | `72` | Hours before park schedule data is considered stale and re-fetched. Lower values increase API load; higher values increase data lag. |
+| `RATE_LIMIT_PER_MIN` | `60` | Per-IP request limit for the public API. Over-limit requests return `429 Too Many Requests` with a `Retry-After` header. Enforced by `backend/src/middleware/rate-limit.ts`. Behind a proxy, ensure `x-forwarded-for` is set or every client looks like the proxy IP. |
+| `NODE_ENV` | -- | Set to `production` in Docker. |
+| `PORT` | `3001` | Server listen port. |
+
+`backend/src/config.ts` parses and validates these at startup. A bad value (e.g. `PORT=foo`) fails fast with a thrown `Error` rather than surfacing in a request handler later.
+
+---
+
+## CI/CD Pipeline
+
+### Gitea Actions Workflow
+
+**File:** `.gitea/workflows/deploy.yml`
+
+**Trigger:** Push to `main` branch.
+
+**Steps:**
+1. Checkout code (`actions/checkout@v4`)
+2. Log in to Gitea container registry
+3. Build and push `web` image (`docker/build-push-action@v6`, target: `web`)
+4. Build and push `backend` image (`docker/build-push-action@v6`, target: `backend`)
+
+### Required Configuration
+
+| Type | Name | Description |
+|------|------|-------------|
+| Variable | `REGISTRY` | Container registry URL (e.g. `gitea.thewrightserver.net`) |
+| Secret | `REGISTRY_TOKEN` | Authentication token for the registry |
+
+These are configured in the Gitea repository settings under **Settings > Actions > Secrets** and **Settings > Actions > Variables**.
+
+### Setting Up CI/CD from Scratch
+
+1. Create a Gitea repository
+2. Add `REGISTRY` as a repository variable (Settings > Actions > Variables)
+3. Add `REGISTRY_TOKEN` as a repository secret (Settings > Actions > Secrets)
+4. Push to `main` -- the workflow triggers automatically
+5. Pull images on your Docker host: `docker compose pull && docker compose up -d`
+
+---
+
+## Initial Deployment Checklist
+
+1. **Create a `docker-compose.yml`** on your Docker host (see the Docker Compose section above, or use the one from the repository).
+
+2. **Pull and start the containers:**
+   ```bash
+   docker compose pull
+   docker compose up -d
+   ```
+
+3. **Verify the backend started:**
+   ```bash
+   docker compose logs backend
+   # Look for (structured log lines, see the Log Reference section):
+   #   [INFO] [startup] database initialized
+   #   [INFO] [scheduler] cron jobs registered ...
+   #   [INFO] [startup] listening url=http://localhost:3001
+   ```
+
+4. **Check database status (will be empty on first run):**
+   ```bash
+   curl http://localhost:3001/api/status
+   # { "status": "ok", "database": { "totalDays": 0, ... } }
+   ```
+
+5. **Trigger the initial data scrape:**
+   ```bash
+   curl -X POST http://localhost:3001/api/scrape/trigger?scope=full
+   ```
+   This scrapes all 12 months for all 24 parks with a 1-second delay between parks. **Expected duration: 5-10 minutes.**
+
+6. **Verify data was scraped:**
+   ```bash
+   curl http://localhost:3001/api/status
+   # totalDays should be ~8000-9000
+   ```
+
+7. **Open the web UI:** Navigate to `http://your-host:3000`.
+
+The cron scheduler starts automatically and will keep data fresh going forward.
+
+---
+
+## Updating
+
+```bash
+docker compose pull && docker compose up -d
+```
+
+- The SQLite database lives in a named Docker volume (`park_data`), so it persists across container recreations.
+- Schema migrations are applied automatically on backend startup. New columns are added via `ALTER TABLE ... ADD COLUMN` wrapped in try/catch -- if the column already exists, the error is silently caught.
+- No manual migration steps are needed.
+
+---
+
+## Backup and Restore
+
+### What to Back Up
+
+The SQLite database at `/app/backend/data/parks.db` inside the `park_data` Docker volume. WAL journal files (`parks.db-wal` and `parks.db-shm`) must be included for a consistent backup.
+
+### Backup Methods
+
+**Method 1: Copy from the container**
+```bash
+docker compose cp backend:/app/backend/data/parks.db ./backup/parks.db
+docker compose cp backend:/app/backend/data/parks.db-wal ./backup/parks.db-wal 2>/dev/null
+docker compose cp backend:/app/backend/data/parks.db-shm ./backup/parks.db-shm 2>/dev/null
+```
+
+**Method 2: Mount the volume to the host**
+Add a bind mount in `docker-compose.yml`:
+```yaml
+volumes:
+  - ./data:/app/backend/data
+```
+
+### Restore
+
+1. Stop the backend: `docker compose stop backend`
+2. Replace the database files in the volume
+3. Restart: `docker compose start backend`
+
+### Note on Reproducibility
+
+All data is sourced from external APIs and is fully reproducible. If the database is lost, simply restart the backend (which auto-creates an empty database) and trigger a full scrape:
+```bash
+curl -X POST http://localhost:3001/api/scrape/trigger?scope=full
+```
+
+Backups are recommended for continuity (avoiding the 5-10 minute re-scrape window) but are not critical.
+
+---
+
+## Scheduler Operations
+
+### Tiered Cron Schedule
+
+The backend runs five scraping tiers via `node-cron`:
+
+| Tier | Cron Expression | Schedule | Scope | Delay |
+|------|-----------------|----------|-------|-------|
+| 1 | `0 * * 3-12 *` | Hourly, March through December | Today's hours for all parks | 500ms |
+| 2 | `0 */6 * * *` | Every 6 hours | Current month for all parks | 1000ms |
+| 3 | `0 3,15 * * *` | 3 AM and 3 PM | Current + next month | 1000ms |
+| 4 | `0 3 * * *` | Daily at 3 AM | Full year (all 12 months) | 1000ms |
+| 5 | `*/5 * * * *` | Every 5 minutes | Wait-time samples for currently-open parks into `ride_wait_samples` | parallel chunks of 6 |
+
+**Staleness:** Tiers 2-4 skip any park-month that was scraped within `PARK_HOURS_STALENESS_HOURS` (default 72h). Tier 1 always fetches (uses diff-before-write instead). Tier 5 only samples parks whose `park_days` row marks them open today *and* whose current local time is inside the operating window (with a 1-hour closing buffer).
+
+**Off-season:** Tier 1 only runs from March through December. The month constraint `3-12` in the cron expression skips January and February when most parks are closed. Tier 5 runs year-round but is effectively a no-op when no parks are open.
+
+**Concurrency latches:** Every tier is wrapped in `withLatch()` (see `backend/src/services/scheduler.ts`). If a tick is still running when the next would fire, the new tick is *skipped* and logged with a `previous run still in progress` warning rather than stacking. Each tier has its own latch so a slow Tier-4 doesn't block Tier-5's 5-minute cadence.
+
+**Weather-delayed parks skipped from sampling:** Tier 5 detects the "rides exist but all closed during scheduled hours" case and skips writes for that park, so a storm doesn't poison the uptime statistics with hours of `is_open=0` samples.
+
+### Startup Behavior
+
+On boot, the scheduler checks `getParkDayCount()` against a threshold of 50 rows:
+
+- **Empty / nearly-empty database** (< 50 rows): runs `scrapeToday()` followed by `scrapeFullYear()` in sequence. Logs `[scheduler.startup]` lines for each phase.
+- **Populated database** (≥ 50 rows): skips the startup scrape and relies on cron tiers. Logs `skipping startup scrape — relying on cron`.
+
+This replaces the earlier behavior of full-scraping on every container start, which doubled outbound API load and delayed readiness on every deploy.
+
+### Timezone Sensitivity
+
+Cron expressions execute in the process timezone, controlled by the `TZ` environment variable. In production this is set to `America/New_York` so that "3 AM" aligns with US Eastern time.
+
+The per-park timezone (e.g. `America/Los_Angeles` for Magic Mountain) is used separately for operating window detection -- it does not affect cron schedule timing.
+
+### The 3 AM Switchover
+
+`getTodayLocal()` in `lib/env.ts` implements a 3 AM local-time switchover: before 3 AM, the system considers it "yesterday." This prevents the calendar from flipping to the next day at midnight while park visitors are still out. The switchover uses the server's local time (influenced by `TZ`), not individual park timezones.
+
+---
+
+## Manual Scraping
+
+Trigger a scrape at any time via the backend API:
+
+```bash
+curl -X POST http://localhost:3001/api/scrape/trigger?scope=<scope>
+```
+
+### Scope Options
+
+| Scope | Behavior | Duration |
+|-------|----------|----------|
+| `today` | Fetches today's hours for all 24 parks. Diffs against database before writing. 500ms delay. | ~15s |
+| `month` | Current month for all parks. Respects staleness window. 1000ms delay. | ~30s |
+| `upcoming` | Current + next month. Respects staleness. | ~1min |
+| `full` | All 12 months. Respects staleness. | ~5-10min |
+| `force` | All 12 months. **Ignores staleness** -- forces re-fetch of everything. | ~5-10min |
+
+### Response
+
+```json
+{
+    "scope": "today",
+    "fetched": 24,
+    "skipped": 0,
+    "errors": 0,
+    "updated": 3,
+    "startedAt": "2026-04-23T14:00:00.000Z",
+    "finishedAt": "2026-04-23T14:00:12.000Z"
+}
+```
+
+### Typical Use Cases
+
+- **After initial deployment:** `scope=full` to populate the database
+- **After an extended outage:** `scope=force` to refresh all data regardless of staleness
+- **Investigating a specific park:** `scope=today` to get fresh data quickly
+- **Before peak season:** `scope=full` to ensure complete coverage
+
+---
+
+## Health Monitoring
+
+### Health Endpoint
+
+```bash
+curl http://localhost:3001/api/status
+```
+
+### Response
+
+```json
+{
+    "status": "ok",
+    "uptime": 86400,
+    "parks": 24,
+    "database": {
+        "totalDays": 8760,
+        "lastScrape": "2026-04-23T14:00:12.000Z"
+    },
+    "lastScrapeResult": {
+        "scope": "today",
+        "fetched": 24,
+        "skipped": 0,
+        "errors": 0,
+        "updated": 3,
+        "startedAt": "2026-04-23T14:00:00.000Z",
+        "finishedAt": "2026-04-23T14:00:12.000Z"
+    }
+}
+```
+
+### Key Metrics
+
+| Metric | Expected Value | Concern If |
+|--------|---------------|------------|
+| `status` | `"ok"` | Not `"ok"` (always `"ok"` currently, but confirms the endpoint is reachable) |
+| `uptime` | Increasing | Drops to 0 (container restarted) |
+| `database.totalDays` | 8,000-9,000 (full year) | Much lower (scraping not running) or 0 (empty database) |
+| `database.lastScrape` | Within the last hour (during operating season) | More than a few hours old (scheduler may be broken) |
+| `lastScrapeResult.errors` | 0 | Consistently high (API may be blocking requests) |
+
+### Suggested Alerting
+
+- Alert if `database.lastScrape` is more than 12 hours old during operating season (March-December)
+- Alert if `lastScrapeResult.errors` exceeds 5 on consecutive scrapes
+- Alert if the health endpoint is unreachable
+
+---
+
+## Troubleshooting
+
+### No data showing in the calendar
+
+1. **Check if the backend is running:**
+   ```bash
+   docker compose logs backend --tail 50
+   ```
+   Look for an `[INFO] [startup] listening url=http://localhost:3001` line.
+
+2. **Check if the database has data:**
+   ```bash
+   curl http://localhost:3001/api/status | jq .database.totalDays
+   ```
+   If 0, trigger a manual scrape: `curl -X POST http://localhost:3001/api/scrape/trigger?scope=full`
+
+3. **Check the BACKEND_URL in the web container:**
+   ```bash
+   docker compose exec web env | grep BACKEND_URL
+   ```
+   Should be `http://backend:3001` (not localhost, which won't resolve inside Docker).
+
+### Ride counts not appearing on the home page
+
+- Ride counts only appear for parks that are **currently within their operating window**, as determined by `isWithinOperatingWindow()`. Outside of park hours, no rides are shown.
+- Queue-Times data is cached for 5 minutes. Recent park openings may take up to 5 minutes to appear.
+- **Weather delay** (blue badge) means the park is within its hours but all rides report closed -- this is expected during weather-related closures.
+- Verify the park has a Queue-Times mapping in `lib/queue-times-map.ts`.
+
+### Stale data / not updating
+
+1. **Check scheduler logs:**
+   ```bash
+   docker compose logs backend | grep scheduler
+   ```
+   You should see periodic `[scheduler] tier-X: scraping...` messages.
+
+2. **Verify timezone:**
+   ```bash
+   docker compose exec backend date
+   ```
+   Should match the `TZ` environment variable (`America/New_York`).
+
+3. **Check staleness threshold:** Data within `PARK_HOURS_STALENESS_HOURS` (default 72h) is skipped by tiers 2-4. If you recently changed park data manually, it may not be re-fetched until the staleness window expires.
+
+4. **Force a refresh:**
+   ```bash
+   curl -X POST http://localhost:3001/api/scrape/trigger?scope=force
+   ```
+
+### Rate limited by Six Flags API
+
+- Look for `[rate-limited]` messages in the backend logs:
+  ```bash
+  docker compose logs backend | grep rate-limited
+  ```
+- The client uses exponential backoff: 30s, 60s, 120s, then throws a `RateLimitError` and moves to the next park.
+- If rate limiting is persistent, increase `PARK_HOURS_STALENESS_HOURS` to reduce scrape frequency (e.g. 96 or 120).
+- The inter-park delay is hardcoded at 1000ms (500ms for the today tier) in `backend/src/services/scraper.ts`.
+
+### Wrong timezone / incorrect dates
+
+- `getTodayLocal()` uses the server's local time (set by `TZ` env var) with a 3 AM cutover. Before 3 AM, the system considers it "yesterday."
+- Each park has its own IANA timezone (stored in `lib/parks.ts`) used for operating window checks. The `TZ` env var only affects cron schedule timing and the "today" determination.
+- If dates seem off, check both `TZ` and the server's system clock:
+  ```bash
+  docker compose exec backend date
+  docker compose exec backend node -e "console.log(new Date().toISOString())"
+  ```
+
+### Database corruption
+
+If the database becomes corrupted (unlikely with SQLite WAL mode, but possible after a hard crash):
+
+1. Stop the backend: `docker compose stop backend`
+2. Delete the database files from the volume:
+   ```bash
+   docker compose run --rm backend rm -f /app/backend/data/parks.db /app/backend/data/parks.db-wal /app/backend/data/parks.db-shm
+   ```
+3. Restart: `docker compose start backend` (auto-creates empty database)
+4. Re-scrape: `curl -X POST http://localhost:3001/api/scrape/trigger?scope=full`
+
+---
+
+## Log Reference
+
+The backend uses a small structured logger (`backend/src/log.ts`). Every line has the format:
+
+```
+<ISO timestamp> [<LEVEL>] [<tag>] <message> key1=value1 key2=value2 …
+```
+
+Levels are `INFO`, `WARN`, `ERROR`. `ERROR` writes to stderr; the others write to stdout. Grep-friendly: filter by tag (`grep '\[scheduler.tier1\]'`) or by key (`grep 'park=cedarpoint'`).
+
+| Tag | Source | Meaning |
+|-----|--------|---------|
+| `startup` | `index.ts` | Config loaded, DB initialized, server listening |
+| `shutdown` | `index.ts` | `SIGTERM`/`SIGINT` received; graceful shutdown progress |
+| `http` | `index.ts` | One line per request: `method`, `path`, `status`, `ms` |
+| `scheduler` | `scheduler.ts` | Cron job registration summary on boot |
+| `scheduler.tier1` … `scheduler.tier5` | `scheduler.ts` | Each tier's tick; includes skip-due-to-latch warnings |
+| `scheduler.startup` | `scheduler.ts` | Result of the "database empty" startup scrape |
+| `today` / `month` | `scraper.ts` | Per-park / per-month scrape results |
+| `wait-sampler` | `wait-sampler.ts` | Tier-5 per-park sample writes, errors, weather-delay skips |
+| `rate-limit` | `middleware/rate-limit.ts` | `blocked` event with `ip`, `count`, `retryAfter` |
+| `rides` | `routes/rides.ts` | Per-request warnings when upstream calls fail |
+| `rate-limited` | `lib/scrapers/sixflags.ts` | HTTP 429/503 from Six Flags with backoff timing |
+
+**Example log output:**
+
+```

+
+## Performance Tuning
+
+| Aspect | Current Setting | Notes |
+|--------|----------------|-------|
+| SQLite WAL mode | Enabled | Allows concurrent reads during writes. No configuration needed. |
+| In-memory cache | TtlCache (5 min TTL) | Bounded by park count -- at most ~72 entries (24 parks x 3 caches). Memory impact is negligible. |
+| Staleness window | 72 hours | Controls how often park data is re-fetched from the API. Lower values = fresher data but more API calls and higher rate-limit risk. |
+| Inter-park delay | 1000ms / 500ms | Hardcoded in `scraper.ts`. Provides respectful pacing against the Six Flags API. |
+| ISR revalidation | 60-300s per route | Controlled in Next.js fetch calls. Lower values = fresher pages but more backend requests. |
+| Next.js standalone | Enabled | Produces a minimal server bundle without unused dependencies. |
