+# Writing a game template
+
+House rules for `games/<id>/game.yaml` and `test.yaml`. They apply to people and to the AI builder alike;
+the builder reads this file as its instructions. Most rules exist because breaking them broke a real server.
+`gbrgames validate` and `gbrgames inspect-image -game <id>` enforce what they can.
+
+## How a server actually runs
+
+Know this before writing anything:
+
+- The node-agent creates one Docker volume per server and mounts it at **both `/server` and `/data`**.
+  Game files, saves and config live there. Anything written elsewhere is lost when the container is
+  recreated, which happens on every start.
+- The container runs as **`1000:1000`** unless the template sets `containerUser`. Never as root.
+- Every key in `defaultConfig` (merged with the owner's changes) reaches the container as an
+  **environment variable**, named by the agent's rule: insert `_` before an upper-case run that follows a
+  lower-case letter, then upper-case everything. `ServerName` → `SERVER_NAME`, `MaxPlayers` →
+  `MAX_PLAYERS`, `RCONPort` → `RCONPORT` (no underscore: no lower-case letter before `P`),
+  `bIsPvP` → `B_IS_PV_P`.
+- If `configFilePath` is set, the same settings are also written to that file in `configFileFormat`
+  before each start.
+- `defaultStartupCommand`, when set, runs as `bash -c "… cd /server && <command>"`; otherwise the
+  image's own entrypoint runs.
+- `installMethod: STEAMCMD` installs `installConfig.appId` into `/server` with anonymous SteamCMD before
+  the server starts.
+- Nodes reach a server's RCON, REST and query ports **over the Docker network**, never through
+  published ports.
+
+## Rules
+
+### Passwords and secrets
+- Admin, RCON and REST passwords: `defaultConfig` value `""`, and the `configSchema` property gets
+  `"x-generate": {"type": "password"}`. The panel then gives every server its own password.
+  **Never put a placeholder or default password in a template.** Shared defaults are readable by anyone
+  from the public game list.
+- Join passwords stay `""`, with `"x-savedValue": {"key": "GAME_JOIN_PASSWORD", "label": "Game join password", "secret": true}`.
+- No real credentials, tokens or IDs anywhere in this repo. A value a server can't start without (a
+  player ID, a license token) goes in `test.yaml` under `secrets`, mapped to a CI secret name.
+
+### Ports
+- `defaultPorts` lists **only what players connect to** (game and query ports). RCON, REST and admin
+  ports are **never** published.
+- Use `"7777/udp"` or `"8211:8211/udp"`. Every port needs its protocol.
+
+### The container user
+- Run `gbrgames inspect-image -game <id>`. If the image is built around its own user (it declares
+  `USER`, or locks a home folder to a uid other than 1000), set `containerUser` to that `uid:gid`.
+  Example: ARK's image needs `25000:25000`.
+
+### The startup command
+- Read settings under the names the agent gives them (see above). `${RCON_PORT}` when the setting is
+  `RCONPort` silently ignores the owner's value; it arrives as `RCONPORT`.
+- Use `${VAR:-default}` for anything that may be unset.
+- If the image installs the game itself on start, make sure a failed install is retried rather than
+  starting a server that isn't there (see ARK's template).
+
+### Memory
+- `requiredMemoryMb` is the container's hard limit. A JVM or engine heap must stay about **1 GB below**
+  it: Minecraft's `MEMORY` is `3G` for `4096` MB. A heap equal to the limit is killed on start.
+
+### Settings (`defaultConfig` and `configSchema`)
+- Take keys and default values from what the server really writes: run
+  `gbrgames first-boot -game <id>` and read the settings in its report.
+- Every key in `defaultConfig` has a `configSchema` property, and the other way round.
+- Every property has a `title`, a short `description` for a player, a `type`, a `default` equal to the
+  `defaultConfig` value, and a `category`: one of `Security & Access`, `Gameplay & Rules`,
+  `World & Environment`, `System & General`. Mark the few that matter when deploying with
+  `"showOnDeploy": true`.
+- An EULA or other agreement is a boolean with `"x-consent": {"label": "...", "url": "..."}` and
+  default `false`. Never `true`; the owner accepts it themselves.
+- Keys may only use letters, digits, `_`, `-` and `.`.
+- Placeholders the panel fills in: `{SERVER_NAME}`, `{PUBLIC_IP}`, `{PUBLIC_HOST}`,
+  `{PUBLIC_PORT_<port>}`, `{saved:KEY}`. Server names default to `GBRHosting - {SERVER_NAME}`.
+
+### Being ready
+- `readyPattern`: a regex that matches the line the server prints once players can join. Take it from a
+  first boot (its report suggests one), and put that real line in `test.yaml` as `readyExample`;
+  validation checks the pattern matches it.
+- `failPatterns`: lines that mean the server will never come up (e.g. an unaccepted EULA).
+- No reliable ready line: leave `readyPattern` out, and the boot test checks the server stays up
+  (`settleSec` in `test.yaml`, default 120 s).
+
+### `test.yaml`
+- `config`: only what the server can't start without in CI (accepting the EULA, for example).
+- `secrets`: required values that can't be public, mapped to CI secret names.
+- `timeoutSec` covers install plus start; SteamCMD games need 2400 or more.
+
+### Commands and players (`agnosticCommandConfig`)
+- Kick, ban, save and broadcast go through RCON or REST using the server's own password key
+  (`passwordKey` / `rconPasswordKey` pointing at the `x-generate` setting). If a game has neither, mark
+  the action `"type": "UNSUPPORTED"`; never invent one.
+- `playerJoinRegex` / `playerLeaveRegex` capture the player name from real log lines.
+
+## Before opening a PR
+
+```bash
+go run ./cmd/gbrgames validate
+go run ./cmd/gbrgames inspect-image -game <id>
+go run ./cmd/gbrgames first-boot -game <id>     # on a machine with Docker and the gbr-boottest network
+```
+
+CI then boot-tests the changed game with the node-agent's real deploy code before anything reaches the panel.
