# Demo mode — `demo.runicgateway.com`

**Status:** design. The org lead answered §9 Q1-Q9 on 2026-10-23 (recorded as decisions DM1-DM10
in §9); three follow-up questions in §9.2 remain. Nothing is built.
**Issue:** `RunicGateway/website#222`. **Why now:** Google Play (`../android/PLAN.md` item 9,
M8) needs a public HTTPS site with working sign-ins for its reviewers and for the 12 testers who
must be opted in for 14 days before the app can apply for production.

## 1. What the demo is

A public Runic Gateway deployment at `demo.runicgateway.com`, linked to the **Oxide Rust rig**,
that anyone can sign into with published accounts. The org lead set three requirements on
2026-10-23:

1. **Static logins.** Ready-made accounts (player, moderator, admin, and one for Google's
   reviewer) whose names and passwords are published.
2. **No destructive actions.** Someone signed in as the public admin must not be able to break the
   site for the next visitor, or reach through it to damage the rig.
3. **An automatic wipe** every couple of hours that brings the site back to a known base: the Rust
   module, the link to the rig, the demo accounts and the seeded content.

The `demo-site` Gitea Actions runner is where the demo is deployed and wiped. The runner is only the
host for those jobs; the design below covers what runs there.

## 2. Principle: the same image, switched by one flag

The demo runs the normal `website-app` image and the normal Rust module release. Nothing is forked.
A single env var on the deployment, **`DEMO_MODE=true`**, turns on three things:

- a **lock** on a fixed list of write routes (§3), answered before the route's own handler runs;
- a **banner** on every page and in the app saying this is a demo and when it next resets (§6);
- **no outbound side effects** that reach a real person (§5).

With the flag unset, none of the demo code runs, so a normal shard is unaffected.

## 3. The lock

### 3.1 How it works

A core middleware, mounted ahead of every router when `DEMO_MODE` is on, compares each write
request (`POST`/`PUT`/`PATCH`/`DELETE`) against a deny list of method + path patterns. A match
answers:

```
403 { "message": "This is turned off on the demo site.", "code": "DEMO_LOCKED" }
```

The web client shows the message as a toast wherever an action fails with that code. The Android
app maps the code to a new error kind with the same wording; today it would show the generic
"Something went wrong", which is misleading for a reviewer.

Reads are never locked. Every page can be opened and every form filled in; only the save is
refused. That keeps the demo useful as a tour of the admin panel.

**The server is the lock, never the UI (DM10).** Every lock is enforced at the route, so a request
sent with `curl`, an old app build, or a hand-edited page is refused exactly like a click. The UI may
explain a lock (the toast, the banner) but never hides or disables a control as the means of
locking it, and no client-side check is relied on.

Module routes are mounted by core but belong to the module, so the module declares its own locked
routes in `module.json` (DM1, §3.2).

### 3.2 The module's declaration

`module.json` gains an optional `demoLocks` list, read by core when `DEMO_MODE` is on:

```json
"demoLocks": [
  { "method": "PUT",    "path": "/admin/rust/servers/:id" },
  { "method": "DELETE", "path": "/admin/rust/servers/:id" },
  { "method": "POST",   "path": "/admin/rust/config/:serverId/file" }
]
```

Paths use the same `:param` syntax as the module's routers and must sit under the module's own
mounts, which the loader checks the same way it checks `mounts`. A module without the field is
unaffected. It is a new manifest field, so `MODULE_API_VERSION` gets a **minor** bump,
`MODULE_API.md` documents it, and the Integration Kit's module chapter gains a paragraph (its
`ci/core-ref.json` pin then moves, as for any API bump).

### 3.3 What is locked

Paths are relative to `/api/v1`. **Tier A** would break the site for the next visitor and is always
locked. **Uploads** are locked hard. **Tier B** (the rig) and **Tier C** (content) stay **open**: the
wipe puts them back (§7).

**Tier A — always locked (core)**

| Area | Routes | What a visitor could otherwise do |
| --- | --- | --- |
| Site mode | `PUT /admin/site-mode` | Put the site into maintenance; every non-admin is locked out |
| Modules | every write under `/admin/modules` (install, sources, restart, enable, disable, purge, delete) | Disable or purge the Rust module; restart the server |
| SSO providers | writes under `/admin/auth/providers` | Add a sign-in provider pointing anywhere |
| Email | `PUT /admin/email/config`, `POST /admin/email/test`, `POST /admin/email/disconnect` | Connect a mail account; send mail from the site |
| Discord bot | `PUT /admin/discord-bot/config` | Point the bot at someone's server |
| Team voice | writes under `/admin/teams/voice` | Configure or sync Discord voice channels |
| Demo accounts, by an admin | `PUT`/`DELETE /admin/users/:id`, `DELETE …/trusted-devices…`, `POST …/mfa/reset` **when `:id` is a demo account** | Demote, disable or delete the account everyone signs in with |
| Own account, on a demo account | `PATCH /auth/me/account/username`, `…/password`, `…/email`; `POST /auth/me/account/totp/setup`, `…/enable`, `…/disable`; `POST /auth/me/account/recovery-codes/generate`; `DELETE /auth/me/account/identities/:provider` | Change the shared password, or turn on 2FA so nobody else can sign in |
| Other people's sessions | `DELETE /auth/me/sessions/:id` for a session that is not the caller's | Sign every other visitor out of the shared account |
| Password reset | `POST /auth/password/forgot`, `POST /auth/password/reset/:token` | Reset a demo account's password |

**Tier A — always locked (Rust module)**

| Area | Routes | Why |
| --- | --- | --- |
| The link to the rig | `PUT`/`DELETE /admin/rust/servers/:id` | Repoint or delete the sidecar link; the site goes dark |
| Plugin config files | `POST /admin/rust/config/:serverId/file` | Writes a plugin's config file on the rig's disk |

**Settings stay open (DM2).** Theme, navigation and the other `PUT /admin/settings` values can be
changed and come back at the wipe. Brand images are uploads, so they fall under the upload lock.

**Uploads — locked hard (DM4)**

| Route | What it stores |
| --- | --- |
| `POST /admin/uploads` | The media library |
| `POST /admin/posts/upload` | Images in posts |
| `POST /admin/settings/brand-asset/:slot` | Logo, hero, favicon |
| `POST /player/teams/:slug/forum/uploads` | Images in team forum posts |

"Hard" means a second rule beside the list: with `DEMO_MODE` on, core refuses **any** request whose
body is `multipart/form-data`, before a router sees it. An upload route added later is locked
without anyone remembering to list it, and a module cannot open one.

**Tier B — the rig: open, reset by the wipe (DM3).** Permission writes (policy, grant, revoke,
groups, members, drift actions, sync), RunicNPC writes (factions, profiles, placements, push,
respawn), economics and permission grants to a linked player, the world actions events run, and map
fetch/render all work. The rig starts every cycle from a **demo default set** of permissions, NPCs
and events, and the wipe restores it (§7.1). Console-command steps are the exception that needs a
rule of their own (§9.2 F1).

**Tier C — content: open (DM4).** Posts, wiki, pages, events, teams and team forums, moderation
actions and invites work. The contact form is locked (`POST /public/contact`), because it sends mail
to a person. The demo is served with `X-Robots-Tag: noindex` and a matching `robots.txt`, so nothing
a visitor writes reaches a search engine.

## 4. Static logins

| Account | Role | Notes |
| --- | --- | --- |
| `demo-admin` | admin | The admin panel, read in full; writes per §3 |
| `demo-moderator` | moderator | Moderation queue, appeals |
| `demo-player` | player | Self-service; linked to a stand-in Steam ID that has played on the rig, so the Rust player screens have data (DM6) |
| `play-review` | admin | Google's reviewer. Same powers as `demo-admin`, but a separate account, so a reviewer is never signed out because someone else revoked a session on the shared one |

Usernames and passwords are published on the demo's sign-in page and on runicgateway.com `/beta`.
They are not secrets. The seed recreates them at every wipe, so a password that somehow changed is
back within one cycle. Public registration is **closed** on the demo: there is no mail to verify an
address with (§5), and the static logins cover every role.

## 5. Outbound effects

| Channel | On the demo |
| --- | --- |
| Email | Not configured. Registration closed, password reset locked, digest and engagement mail never send |
| Push (ntfy) | Not deployed. The app's notification settings still save; nothing is delivered |
| Discord bot | Not deployed |
| The rig | Open, and restored to the demo default set at every wipe (§7.1) |

## 6. The banner

`GET /api/v1/public/settings` gains `demo: { resetsAt }` while the flag is on. The web client shows a
thin strip on every page: "Demo site — anything you change is wiped at 14:00 UTC. Sign-ins:
demo-admin / demo-player …". The app shows the same strip on Home. Both read `resetsAt`, so neither
needs to know the schedule.

## 7. The wipe

A scheduled workflow on the `demo-site` runner runs **every 2 hours on the hour, UTC** (DM7). It
resets the rig first and the site second, and the order matters.

### 7.1 Why the rig goes first

The site's first sync with a server **imports what it finds there**. A new site's first permission
read adopts every grant and group on the rig (D198), and RunicNPC profiles are adopted before the
first push (D244). So wiping only the site would bring back every change a visitor made on the rig,
now owned by the fresh site. The rig has to be back at the demo default set **before** the new site
first talks to it. Then that first import *is* the reset: the site adopts the default set, and the
default set never has to be described twice.

### 7.2 The rig: restore a baseline through Pterodactyl (DM3)

The demo rig is the existing `rust-oxide` Pterodactyl server (DM5). On it sits one archive,
`demo-baseline.tar.gz`, holding the demo default set:

- `oxide/data/` — permissions and groups, RunicNPC profiles and placements, Economics balances, the
  bridge plugin's own data;
- `oxide/config/` — plugin configs, so even a config that changed some other way comes back;
- `server/<identity>/` — the world save and `cfg/`, so anything an event built or a console command
  wrote with `server.writecfg` comes back too.

`oxide/plugins/` is **not** in the baseline. Plugin versions are the deployment's business (§9.2
F2), not the wipe's.

The workflow uses the Pterodactyl **client** API (files and power):

1. `POST …/power {"signal":"kill"}` — no save, since the world is about to be replaced.
2. `POST …/files/delete` the three directories.
3. `POST …/files/decompress` `demo-baseline.tar.gz` at the server root.
4. `POST …/power {"signal":"start"}`. Rust takes a few minutes to boot; the site does not wait.

**Capturing the baseline** is a second, hand-run workflow (`workflow_dispatch` only): someone sets up
the default set through the demo site (the permission groups, a handful of NPCs, events), then runs
it. It saves the world (`server.save` over the console), stops the server, `POST …/files/compress`es
the three directories into `demo-baseline.tar.gz`, and starts the server again. Re-run it whenever
the default set should change.

**The key.** Pterodactyl client keys belong to a user and reach every server that user can see. The
demo gets its own Pterodactyl **subuser**, with access to `rust-oxide` only and the file and power
permissions only, and that subuser's client key is the `demo-site` workflow's secret
(`PTERODACTYL_CLIENT_KEY`). The panel URL and server identifier are plain variables.

### 7.3 The site

1. `docker compose down -v` — drops the database **and** the uploads volume.
2. `docker compose pull && docker compose up -d` — the app boots on the latest `main` image, creates
   the schema, and installs the Rust module from `MODULES=rust@<version>=<manifest>` (DM9, §9.2 F2).
3. Wait for the app's healthcheck.
4. `docker compose exec app npm run seed:demo` — one core script that, from a fixture file in the
   deploy directory:
   - creates the four accounts (§4) and `demo-player`'s stand-in Steam link (DM6);
   - creates the Rust server row with the rig's sidecar URL and token taken from `.env`, so the
     link survives every wipe without being stored in the fixture;
   - writes the seeded site content: news posts, wiki pages, the demo events and a team;
   - stamps `resetsAt` for the banner.
5. The module's sync connects when the rig finishes booting, and its first import adopts the
   baseline's permissions and NPCs (§7.1).
6. Smoke check, after a bounded wait: `GET /api/v1/public/status` answers, and the Rust server
   reports a live connection. A rig that has not come back fails the run, and the site still
   serves with the server shown offline.

### 7.4 What a visitor sees

The site is down for about a minute; the rig for a few. Signed-in visitors, including app users,
are signed out, because their sessions and refresh tokens were in the database.

The same workflow runs on `workflow_dispatch` and on a push to `main` that changes `deploy/demo/`,
so a redeploy is the same path as a wipe.

## 8. Where it lives

| Piece | Repo |
| --- | --- |
| `DEMO_MODE` lock, banner field, `seed:demo` script | `website` (core) |
| The Rust module's `demoLocks`, and the console-command rule (§9.2 F1) | `Module-Rust` |
| `DEMO_LOCKED` error kind and the banner in the app | `Android-app` |
| `deploy/demo/` (compose file, `.env.example`, seed fixture) and `.gitea/workflows/demo-wipe.yml` + `demo-baseline.yml` | `website` (DM8) |
| `.env` (JWT secret, encryption key, the rig's sidecar token) | On the `demo-site` host only, never in a repo |
| `PTERODACTYL_CLIENT_KEY` (the demo subuser's key) | A Gitea Actions secret on `website` |
| `demo-baseline.tar.gz` | On the rig, at the Pterodactyl server root |

## 9. Decisions and open questions

### 9.1 Decisions (org lead, 2026-10-23)

| # | Question | Decision |
| --- | --- | --- |
| DM1 | How the module declares its locked routes | A `demoLocks` list in `module.json`; `MODULE_API` minor bump (§3.2) |
| DM2 | Is anything on Tier A to stay open? | Settings stay open (theme, navigation and the rest of `PUT /admin/settings`); the rest of Tier A stays locked (§3.3). See F3 |
| DM3 | What may a visitor do to the rig? | Permissions, NPCs and events start from a **demo default set**, can be changed through the site, and are put back each cycle by a CI script that restores the rig through Pterodactyl (§7.2) |
| DM4 | May visitors publish content? | Yes. **Uploads are locked hard** (§3.3); the contact form is locked; the site is `noindex` |
| DM5 | Which rig? | The existing Oxide rig becomes the demo's. A new Oxide server is spun up for testing when a walk needs one |
| DM6 | A Steam link for `demo-player`? | Yes, a stand-in Steam ID that has played on the rig |
| DM7 | Cadence | Every 2 hours |
| DM8 | Where the files live | `website/deploy/demo/` and `website/.gitea/workflows/` |
| DM9 | Version | Latest, at every wipe |
| DM10 | (the org lead, unprompted) | **Every lock is at the server route level, never the UI level** (§3.1) |

DNS and HTTPS for `demo.runicgateway.com` come from an external reverse proxy, which the org lead is
setting up. The app sits behind it on plain HTTP; core already trusts one proxy hop for
`X-Forwarded-*` by default (`TRUST_PROXY`), and the deploy PR checks secure cookies and client IPs
through that proxy.

### 9.2 Follow-up questions

**F1 — Console-command steps on the demo.**
Example: `demo-admin` adds a console-command step with `quit` to an event and starts it. The Rust
server stops and stays down until the next wipe, up to two hours, for every visitor. Other commands
do the same more quietly: `oxide.unload RunicGateway` cuts the site off from the rig, and
`kickall` and `ban` affect anyone playing. The command box is free text with no allowlist today
(Rust §16).
- **(a) Recommended:** on the demo, the module accepts a command step or command reward only if its
  command is on a short allowlist, for example `say`, `env.time`, `weather.*` and `server.time`.
  The module checks it when the event is saved **and** when the step runs, so it is a server-side
  rule (DM10). Everything else in events stays open.
- (b) Refuse command steps and command rewards entirely on the demo.
- (c) Leave them open; the wipe is the cleanup, and the rig may be down until it.

**F2 — "Latest" across the website, the module and the rig.**
Example: Module-Rust ships a release that needs protocol 15 while the rig's bridge plugin still
speaks 14. At the next wipe, the demo pulls the new module, and the site refuses the rig until
someone updates the plugins.
- **(a) Recommended:** the demo follows the latest **Rust bundle**, the protocol-checked set of
  module, sidecar and plugins that CI already publishes. When the bundle changes, the wipe also
  puts the bundle's plugins and sidecar onto the rig through the same Pterodactyl file API. The
  website image always follows `main`.
- (b) Latest module at every wipe, and the rig's plugins updated by hand when a release needs it.

**F3 — DM2, read correctly?**
"Stay open" is read as: the settings (theme, colours, navigation, site texts) stay open, and every
other Tier A row stays locked, including site mode, modules, SSO, email, Discord, the demo
accounts' credentials and 2FA, and the rig link. Is that right?

**For the org lead to set up (not questions):** a Pterodactyl subuser with access to `rust-oxide`
only (file and power permissions), and its client key as the `PTERODACTYL_CLIENT_KEY` secret on
`website` (§7.2). Also confirm that the `demo-site` host can reach the Pterodactyl panel and the
rig's sidecar over the network.

## 10. Build order, once §9.2 is answered

1. **Core** (`website`): the `DEMO_MODE` lock (deny list, the `multipart/form-data` rule, the
   demo-account and other-session checks), `demoLocks` loading, the banner field, `seed:demo`,
   `noindex`, the web banner and toast, `MODULE_API` minor bump, and the OpenAPI note that a route
   may answer `DEMO_LOCKED`. Tests for every lock. One PR, plus `MODULE_API.md` and this doc.
2. **Module** (`Module-Rust`): `demoLocks` in `module.json`, and the F1 rule with its tests. One PR.
3. **Kit** (`Integration-kit`): the `demoLocks` paragraph and the `core-ref.json` re-pin. One PR.
4. **App** (`Android-app`): the `DEMO_LOCKED` error kind and the banner on Home. One PR.
5. **Deployment** (`website`): `deploy/demo/`, `demo-wipe.yml` and `demo-baseline.yml`; the first
   deploy on `demo-site`; setting up the default set and capturing the baseline; then a walk of
   every static login, every Tier A lock and the upload lock, in the browser and the app, plus
   one full wipe cycle that restores a changed permission, NPC and event. One PR.
6. **Play**: the sign-in details in the Play Console point at `play-review`;
   runicgateway.com `/beta` publishes the logins.
