Demo mode — demo.runicgateway.com

Status: design, fully decided 2026-10-23 (DM1-DM13, §9). Ready to build per §10. Nothing is built yet. 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:

"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 stay open too, except for the commands on a deny list (§3.4, DM11).

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.

3.4 The console-command deny list (DM11)

Console-command event steps and command rewards are a free-text box with no allowlist (Rust §16). On the demo, the Rust module refuses a command on this deny list, which holds the commands that would break the rig for every visitor until the next wipe. Everything else runs.

Command (any of these spellings)	Why it is denied
quit, restart	Stops or restarts RustDedicated. The rig stays down, or the site loses it for minutes, until the wipe
oxide.unload, oxide.reload (with any argument, * included)	Unloads RunicGateway, which cuts the site off from the rig, or RunicNPC, Kits, ZoneManager and the rest, which the bridge needs
rcon.*	The panel's console runs over RCON, and the wipe's baseline capture uses that console
fps.limit, server.tickrate	Starves the server tick; the rig crawls for every visitor

Matching. The check normalises the command before comparing: it trims it and lower-cases it, strips a leading global. (Rust accepts global.quit), and maps the o. short form to oxide. (o.unload). It compares the first word only, so the arguments cannot hide a denied command. ; does not split console commands in Rust (the §16 spike), so there is no second command to look for.

Where it is enforced (DM10). In the Rust module's server code, at two points:

• when an event or reward holding the command is saved, answering 403 DEMO_LOCKED with the denied command named;
• when the step runs, so an event saved before the list changed is still refused.

The module learns that it runs on the demo from a new read-only ctx.demoMode boolean. That is part of the same MODULE_API minor bump as demoLocks (§3.2). The list lives in the module with tests, and a command added later is a module change.

Commands that only change the world or the players (server.writecfg, entity.*, env.*, weather.*, say, kick, ban, oxide.grant) stay open. The baseline restore puts all of them back (§7.2).

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/ and the sidecar are not in the baseline. Their versions follow the Rust bundle (§7.5, DM12), not the snapshot.

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/compresses 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. Done: the org lead created the subuser and added the secret on 2026-10-23.

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>, which the workflow writes (§7.5).
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.

7.5 Versions: the latest Rust bundle (DM9, DM12)

"Latest" is decided per piece, so the three halves of the Rust link can never disagree on protocol:

Piece	Follows
Website image	website-app:latest, the newest main
Rig plugins + sidecar	The Rust bundle's current.json (installer, branch bundles, v2/rust/). A bundle is the protocol-checked pair of Rust-Link and Rust-Plugins that CI already publishes
Rust module	The newest Module-Rust release whose protocol equals that bundle's protocol

The Rust game link has no 409: a plugin on a different protocol would mis-parse, not be refused. That is why the module is chosen by protocol, not by date.

What the wipe adds. Before §7.2's rig restore, the workflow reads current.json:

1. The bundle changed since the last wipe. It downloads the bundle's plugin tarball and sidecar binary, checks each sha256, and writes them onto the rig through the same Pterodactyl file API while the server is stopped. That means the plugin files into oxide/plugins/, and the sidecar and its with-sidecar.sh launcher where the egg expects them. It records the bundle tag on the demo-site host.
2. Always. It picks the module release as above, and writes MODULES=rust@<version>=<manifest> into the deploy directory's .env before §7.3.

Module-Rust's release CI adds protocol (read from PROTOCOL_VERSION in server/sidecarClient.js) to the install manifest it already publishes, so the choice needs no guessing. Core's installer reads only the fields it names (modules/install.js), so the extra field needs no core change.

If no module release matches the new bundle yet, the wipe keeps the previous bundle and module, finishes the reset on them, and warns in the run. A half-released protocol bump never takes the demo down.

8. Where it lives

Piece	Repo
DEMO_MODE lock, banner field, seed:demo script	website (core)
The Rust module's demoLocks, the console-command deny list (§3.4), and protocol in its install manifest (§7.5)	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

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). Confirmed as "settings only" (DM13)
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)
DM11	(F1) Console-command steps on the demo	A deny list of the commands that would break the rig (quit, oxide.unload RunicGateway and the like), not an allowlist; everything else runs (§3.4)
DM12	(F2) What "latest" means across the Rust link	The latest Rust bundle for the rig's plugins and sidecar, the newest module release on the same protocol, and the website's main image; the wipe updates the rig when the bundle changes (§7.5)
DM13	(F3) DM2 read correctly?	Yes: only the settings stay open; every other Tier A row stays locked

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 Set up by the org lead

• Done 2026-10-23: the Pterodactyl subuser (access to rust-oxide only, file and power permissions) and its client key as the PTERODACTYL_CLIENT_KEY Actions secret (§7.2).
• In progress: DNS and HTTPS through the external reverse proxy.
• To confirm in the deploy phase: the demo-site host reaches the Pterodactyl panel and the rig's sidecar over the network.

10. Build order

1. Core (website): the DEMO_MODE lock (the deny list, the multipart/form-data rule, the demo-account and other-session checks), demoLocks loading, ctx.demoMode, the banner field, seed:demo, noindex, the web banner and toast, the 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, the console-command deny list behind ctx.demoMode (§3.4), and protocol in the release's install manifest (§7.5), each with tests. One PR.
3. Kit (Integration-kit): a paragraph on demoLocks and ctx.demoMode, 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 (with §7.5's bundle step) 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, and a denied console command refused at save and at run. One PR.
6. Play: the sign-in details in the Play Console point at play-review; runicgateway.com /beta publishes the logins.
