+# Working on MangaCircus
+
+Guide for contributors and coding agents. Users who only want to run it: [docs/deployment.md](docs/deployment.md).
+
+## Layout
+
+| Path | What |
+|---|---|
+| `server.js`, `library.js` | Reader: HTTP server, accounts, progress, JSON storage; folder scanner and image-size reader |
+| `chapter-identity.js`, `chapter-dates.js`, `reading-*.js`, `catalog.js`, `backup.js` | Shared modules (chapter keys, chapter dates, reading clock/limits, collections, built-in backup) |
+| `public/` | The web pages: plain HTML, CSS and JavaScript, no build step |
+| `scraper/` | Download queue daemon (`service.js`, `daemon.js`), source adapters and parsers, the publisher that writes the library, metadata lookups |
+| `peering/` | Optional server-to-server sharing (gateway, client, adapter) |
+| `runtime/` | In-container supervisor and configuration |
+| `discovery/`, `greatest/` | Discovery Scout and the Greatest of All Time dashboard |
+| `tools/` | Demo library, health checks, maintenance tools (dry run by default), UI and Compose test drivers |
+| `deploy/` | `circus.sh` operations helper, HTTPS with Caddy |
+| `docs/`, `vision/` | Contracts and guides; design notes for planned features |
+
+## Rules
+
+- **No runtime dependencies.** Node.js built-ins only. Playwright is an optional dev tool for UI tests.
+- **One writer per store.** The reader alone writes `DATA` (users, progress, catalog). The scraper alone
+  writes the library and its queue. Tools that edit `chapter.json` files are dry runs by default and need
+  `--apply --writers-stopped`.
+- **Library writes go through the publisher** (`scraper/lib/publisher.js`): staging folder, validated
+  images, one atomic rename. The folder contract is [docs/scraper-guide.md](docs/scraper-guide.md).
+- **Sources are polite.** Sequential requests, persisted per-host delays, stop on 401/403/429, never bypass
+  access controls ([scraper/AGENT_RUNBOOK.md](scraper/AGENT_RUNBOOK.md)).
+- **No secrets or personal data in the repository**: no `.env`, `.secrets/`, `data/`, libraries, host
+  names, IP addresses or local paths. Tests use disposable fixtures and never a real library or user
+  database.
+- Keep the docs current in the same change: a new file format field goes into
+  [docs/library-format.md](docs/library-format.md), a new setting into the README or
+  [docs/deployment.md](docs/deployment.md), an API change into [docs/architecture.md](docs/architecture.md).
+- Match the surrounding style: small functions, short comments that say why, no framework.
+
+## Tests
+
+```bash
+npm test                         # reader, scraper, runtime and peering suites (node --test)
+```
+
+Without Node on the machine, run them in Docker (the peering test needs `openssl`, present in `node:24`):
+
+```bash
+docker run --rm -v "$PWD:/app" -w /app node:24 npm test
+```
+
+Browser and Compose acceptance tests (Playwright, disposable data, never the live stack):
+`npm run test:ui`, `npm run test:discovery-ui`, `npm run test:direction-ui`, `npm run test:peer-ab`.
+
+Try changes against demo data: `node tools/make-dummy.js library && npm run start:all`, or
+`docker compose -f docker-compose.yml -f compose.dev.yml up -d --build` (mounts the editable source).

 - Reader with three view modes (**Flow**, **Page**, **Book**), a page zoom that leaves the controls alone, and tap zones for mobile.

-## Run it
+## Run it with Docker
+
+The supported way to run MangaCircus is Docker Compose on a Linux host: one image, a **reader**
+service (the web app) and a **scraper** service (the managed download queue). Short version:
 
 ```bash
-node server.js
+git clone <repository-url> mangacircus && cd mangacircus
+mkdir -p library data/scraper data/peering data/peering-usage backup .secrets
+openssl rand -hex 32 > .secrets/scraper_token && chmod 600 .secrets/scraper_token

+sudo chown -R 1000:1000 library data backup
+docker compose build
+bash deploy/circus.sh up                  # reader first, then the scraper
 ```

+Open http://127.0.0.1:8080. The first account you create becomes the admin. The full guide covers
+configuration, LAN and HTTPS access (a ready Caddy setup is included), adding manga, updates, backups,
+peering and troubleshooting: **[docs/deployment.md](docs/deployment.md)**.
+
+## Try it without Docker
+
+Needs Node.js 18 or newer, nothing else:
 
 ```bash
-node tools/make-dummy.js library
+node tools/make-dummy.js library      # five demo manga
+npm run start:all                     # reader on :8080 and the scraper daemon on 127.0.0.1:8091
 ```
 
-To run the reader and managed scraper together, use `npm run start:all`. Admins can
-then manage the persistent download queue, progress, pauses, retries, and rate limits
-under **Settings → Admin → Scraper**. The reader continues working if the scraper is stopped.
-**Settings → Admin → Collections & metadata** manages grouped tiles, reading order and relationships;
-**Settings → Admin → Service health** shows recovery incidents. See [collections](docs/collections.md)
-and [resilience](docs/resilience.md) for the ownership and agent-maintenance contracts.
-The current Windows installation uses Docker Compose; its old `MangaCircus Supervisor`
-Scheduled Task is disabled. Do not run a native duplicate writer. See
-[docs/local-deployment.md](docs/local-deployment.md) for its observed layout, health
-checks, restart procedure, and recovery point.
-Deployment-controlled reading hours and the optional progress-aware quiz are
-documented in [reading limiter](docs/reading-limiter.md). They are disabled
-unless configured on the reader container.
-See [Greatest of All Time](docs/greatest.md) for catalog ownership, voting, and metadata refresh.

-### Docker
-
-```bash
-node tools/prepare-compose.js
-docker compose config -q
-docker compose up -d --build
-```
-
-Stop existing native writers before using their data in containers. `docker-compose.yml`
-runs reader and scraper with explicit persistent bind mounts (`library/`,
-`data/`), file-backed secrets and only a loopback reader port. No named data volume is
-used. See [Compose deployment](docs/compose-deployment.md) for local development, VM
-recommendations, cutover, image releases and backup/rollback. The local Docker stack
-is verified; VM deployment is still pending.
+`npm start` runs the reader alone. Admins manage the persistent download queue, pauses, retries and rate
+limits under **Settings → Admin → Scraper**. The reader keeps working when the scraper is stopped.
+**Settings → Admin → Collections & metadata** manages grouped tiles, reading order and relationships, and
+**Settings → Admin → Service health** shows recovery incidents and backups ([collections](docs/collections.md),
+[resilience](docs/resilience.md)). Deployment-controlled reading hours and the optional progress-aware quiz
+are described in [reading limiter](docs/reading-limiter.md); they are off unless configured.

+# Deploying MangaCircus with Docker
+
+This guide sets up MangaCircus on one Linux host with Docker Compose: the reader (web app), the managed
+scraper, and optionally HTTPS and server peering. Every step is a command with what you should see. It is
+written so that a person or a coding agent can follow it without other context.
+
+## 1. What runs
+
+| Service | Port | Role |
+|---|---|---|
+| `reader` | 8080 (published on `READER_BIND`) | Web app: library, reader, accounts, settings. The only writer of users, progress and the catalog (`DATA_PATH`). Reads the library read-only |
+| `scraper` | 8091, internal only | Download queue and source adapters. The only writer of the library (`LIBRARY_PATH`) and of its own state (`SCRAPER_DATA_PATH`). Never publish or proxy this port |
+| `peer-gateway` | 8093, optional (`--profile peering`) | Shares chosen manga with other MangaCircus servers over mutual TLS ([peering.md](peering.md)) |
+
+All services run from one image (`node:24-alpine`, no runtime dependencies) as uid/gid 1000. Each container
+has a read-only root file system, no capabilities, rotated logs, a health check and an in-container
+supervisor that restarts a crashed process. The reader works when the scraper is stopped.
+
+Data on the host, all bind mounts (no named volumes):
+
+| Path (`.env`) | Contents | Back up? |
+|---|---|---|
+| `LIBRARY_PATH` | The manga: `Manga/Book/Chapter/images` ([library-format.md](library-format.md)) | Yes, it is your collection |
+| `DATA_PATH` | `db.json` (users, progress, votes), catalog, library index cache | Yes (built-in backup, section 8) |
+| `SCRAPER_DATA_PATH` | Queue, settings, source ledger, metadata cache | Included in the built-in backup |
+| `BACKUP_PATH` | Built-in backup archives | Keep it on another disk or NAS |
+| `SCRAPER_TOKEN_PATH` | Shared secret between reader and scraper | Regenerate if lost |
+
+## 2. Requirements
+
+- Linux x86_64 or arm64 with Docker Engine 24+ and the Compose plugin 2.24.4+ (`docker compose version`).
+  Docker Desktop on Windows or macOS works for trying it out. Bind mounts are slow there for large libraries.
+- 1–2 CPU cores and 1 GB RAM are enough for a few readers. The first scan of a large library is
+  I/O-bound (about 14 minutes for 300,000 pages on a NAS over NFS). Later starts reuse the index cache.
+- Disk: the library plus room for downloads in progress. The image is about 60 MB.
+- Git to fetch the code. Node is **not** needed on the host.
+
+## 3. Get the code and prepare folders
+
+```bash
+git clone <repository-url> mangacircus && cd mangacircus
+mkdir -p library data/scraper data/peering data/peering-usage backup .secrets
+openssl rand -hex 32 > .secrets/scraper_token && chmod 600 .secrets/scraper_token
+cp .env.example .env
+sudo chown -R 1000:1000 library data backup
+```
+
+The containers run as uid 1000: the reader must be able to read the library and write `data/`, and the
+scraper must be able to write the library. On an NFS share with squashed ids, map all users to one account
+that owns the files. Don't use `chmod 777`. Bind mounts never create missing folders: a typo in a path
+fails the start instead of showing an empty library.
+
+Already have a library? Point `LIBRARY_PATH` at it (folder format in [library-format.md](library-format.md)).
+Starting empty? Fill it from the web UI's scraper queue (section 6). To try the reader first, create five
+demo manga in an empty library after the build in section 5:
+`docker compose run --rm --no-deps scraper node tools/make-dummy.js /library`.
+
+## 4. Configure `.env`
+
+| Variable | Default | Meaning |
+|---|---|---|
+| `LIBRARY_PATH` | `./library` | Library folder (absolute path recommended) |
+| `DATA_PATH` | `./data` | Reader data |
+| `SCRAPER_DATA_PATH` | `./data/scraper` | Scraper state |
+| `PEER_DATA_PATH`, `PEER_USAGE_PATH` | `./data/peering`, `./data/peering-usage` | Peering identity and transfer counters (folders must exist even when peering is off) |
+| `SCRAPER_TOKEN_PATH` | `./.secrets/scraper_token` | The secret file from section 3 |
+| `BACKUP_PATH` | unset = backups off | Folder for built-in backups (section 8) |
+| `READER_BIND` / `READER_PORT` | `127.0.0.1` / `8080` | Where the reader listens on the host. `0.0.0.0` = every interface (plain HTTP, LAN only) |
+| `TZ` | `UTC` | Time zone of the containers; affects the nightly update time and backup schedule |
+| `COOKIE_SECURE` | `0` | `1` when readers reach the site over HTTPS |
+| `READING_WINDOWS_JSON`, `READING_TIMEZONE`, `READING_QUIZ_*` | off | Optional server-enforced reading hours ([reading-limiter.md](reading-limiter.md)) |
+| `APP_IMAGE`, `VCS_REF` | `mangacircus:local`, `development` | Image to run; set a pinned registry image to deploy prebuilt releases (section 7) |
+| `COMPOSE_FILE` | `docker-compose.yml` | Extra Compose files, `:`-separated (e.g. `docker-compose.yml:deploy/compose.https.yml`) |
+| `MANGACIRCUS_DOMAIN` | – | Host name for `deploy/compose.https.yml` |
+
+Sign-up is closed: the first account becomes the admin, who then adds the other users. Reader settings
+not listed here (scan intervals, scan concurrency) are in the README's environment table.
+
+## 5. Build and start
+
+```bash
+docker compose config -q            # no output = the configuration is valid
+docker compose build
+bash deploy/circus.sh up            # reader first, waits for its health check, then the scraper
+bash deploy/circus.sh status
+```
+
+Expected:
+
+```
+SERVICE   STATUS                    PORTS
+reader    Up 1 minute (healthy)     127.0.0.1:8080->8080/tcp
+scraper   Up 40 seconds (healthy)   8080/tcp
+{"ok":true,"scan":{"mangas":…,"stale":false,"error":null}, …}
+{"status":"idle","paused":false,"active":0,"queue":0, …}
+```
+
+Open `http://127.0.0.1:8080` (or an SSH tunnel: `ssh -L 8080:127.0.0.1:8080 <host>`) and create the admin
+account. The library page fills as soon as the first scan finishes.
+
+## 6. Access and adding manga
+
+- **On the LAN:** set `READER_BIND=0.0.0.0` (or the host's LAN address), or use `compose.lan.yml` with
+  `READER_LAN_BIND`. This is plain HTTP: logins and cookies travel unencrypted, so never forward it to the
+  internet.
+- **HTTPS with the bundled Caddy:** point a DNS name at the host, open ports 80 and 443, set
+  `MANGACIRCUS_DOMAIN=manga.example.org` and `COMPOSE_FILE=docker-compose.yml:deploy/compose.https.yml`,
+  then `bash deploy/circus.sh up`. Caddy fetches the certificate. The reader gets no host port and secure
+  cookies.
+- **Your own proxy:** keep `READER_BIND=127.0.0.1` and proxy `http://127.0.0.1:8080`. Alternatively, use
+  `compose.vm.yml`, which joins the reader to an external Docker network (`PROXY_NETWORK`, default
+  `mangacircus-edge`) and removes the host port. Set `COOKIE_SECURE=1`. All pages use relative URLs, so a
+  sub-path such as `/manga/` works.
+- **Private access over a VPN** (WireGuard, Tailscale, …): bind the reader to the VPN address, or keep it on
+  loopback and forward from the VPN client.
+- **Adding manga:** admins use **Settings → Admin → Scraper → Inspect & queue** with a series URL from a
+  supported source (WeebCentral, MangaDex, MangaPill), or copy folders into the library by hand. The reader
+  notices new folders within `SCAN_INTERVAL` minutes. Rules for tools that write into the library:
+  [scraper-guide.md](scraper-guide.md). Only download what you are allowed to copy; the scraper keeps
+  conservative per-host rate limits and stops on 401/403/429 ([scraper/AGENT_RUNBOOK.md](../scraper/AGENT_RUNBOOK.md)).
+
+## 7. Operating it
+
+`deploy/circus.sh` wraps the safe sequences (run it from any folder; it finds the repository itself):
+
+| Task | Command | Notes |
+|---|---|---|
+| Status | `bash deploy/circus.sh status` | services, reader health, queue |
+| Stop / start | `… down` / `… up` | `down` pauses the queue and waits for the running chapter (up to 15 minutes); `up` resumes only what `down` paused |
+| Restart | `… restart` or `… restart reader` | |
+| Logs | `… logs scraper 200` | |
+| Pause / resume downloads | `… pause` / `… resume` | Same as the buttons in Settings → Admin → Scraper |
+| Update to the newest code | `… update` | `git pull --ff-only`, rebuild, pause, recreate, resume |
+| Re-read edited `chapter.json` files | `… rescan` | Full reconciliation without an admin login; admins can also use Settings → Admin → Rescan |
+| Check the newest backup restores | `… restore-test` | Throwaway reader without network; prints `RESTORE TEST OK` |
+
+**Deploying prebuilt images** (several hosts, or no building on the server): build once, push to your
+registry and pin the digest:
+
+```bash
+docker build --build-arg VCS_REF=$(git rev-parse --short HEAD) -t registry.example.org/mangacircus:$(git rev-parse --short HEAD) .
+docker push registry.example.org/mangacircus:<commit>          # note the sha256 digest it prints
+# on the server, in .env: APP_IMAGE=registry.example.org/mangacircus@sha256:<digest>
+docker compose pull && bash deploy/circus.sh restart
+```
+
+Pinned digests make rollbacks exact: put the previous `APP_IMAGE` back and restart. Data formats only grow
+(new fields are ignored by older releases), but a rollback does not undo queue or catalog changes made by
+the newer release.
+
+**Rules for operators and agents:**
+- Never run two scrapers, or a container and a native `node` process, against the same library or data
+  folder.
+- Never run `docker compose down -v`. Stop with `deploy/circus.sh down`.
+- Never publish port 8091, and never print or commit `.secrets/` or `.env`.
+- One-off maintenance tools that write `chapter.json` files are dry runs by default. Run them with
+  `--apply --writers-stopped` only after `docker compose stop scraper`, then `deploy/circus.sh rescan`.
+  Examples: `tools/backfill-chapter-dates.js` and `tools/release-dates.js`, run inside the image with
+  `docker compose run --rm --no-deps scraper node tools/<tool>.js /library …`.
+
+## 8. Backups
+
+- **Reader and scraper data:** set `BACKUP_PATH` to an existing folder on another disk or NAS (owned by uid
+  1000), restart, and choose the schedule and retention under **Settings → Service health → Backups**. A
+  run pauses the queue, waits for the current chapter, archives the data folder without stopping anything
+  and resumes. Details, archive contents and the restore procedure: [backup.md](backup.md). Check it now
+  and then with `deploy/circus.sh restore-test`.
+- **The library:** back it up with your usual file backup (it is plain folders and images), including
+  hidden `.mcscraper-*` folders if downloads are in progress.
+- **Restore:** `deploy/circus.sh down`, move the data folder aside, unpack the archive into a fresh data
+  folder (`tar -xzf circus-….tar.gz -C data`, owned by uid 1000), `deploy/circus.sh up`. Restored archives
+  have the queue paused; resume it after checking.
+
+## 9. Optional: server peering
+
+Share selected manga with friends' MangaCircus servers: enable the `peering` profile
+(`docker compose --profile peering up -d peer-gateway`) and follow [peering.md](peering.md). The gateway
+needs its own reachable port (`PEER_BIND`, `PEER_PORT`) and uses mutual TLS with pinned certificates.
+
+## 10. Troubleshooting
+
+| Symptom | Cause / fix |
+|---|---|
+| `docker compose up` fails with "bind source path does not exist" | A folder from `.env` is missing; create it (section 3) |
+| Reader healthy but the library is empty | First scan still running (`docker compose logs reader` shows `[scan] …` when done), or `LIBRARY_PATH` points at the wrong folder |
+| Scraper jobs fail with `EACCES` | The library or `SCRAPER_DATA_PATH` is not writable by uid 1000 |
+| Backups fail with `EACCES` on a NAS | Map the share's users to the uid that owns the folder; the backup probes with a real write |
+| Settings → Scraper says the service is unavailable | Scraper container stopped or unhealthy: `deploy/circus.sh status`, `logs scraper` |
+| Edited `chapter.json` changes don't show | Run `deploy/circus.sh rescan` (in-place edits are picked up by full reconciliations, every 24 hours by default) |
+| Logins fail behind HTTPS | `COOKIE_SECURE=1` needs HTTPS end to end at the browser; with plain HTTP keep it `0` |
+
