# Design Update Log
## 2026-08-08
* **Verify**: Added encrypted, allowlisted administrator RCON connection management with credential-safe audits and a generated Drizzle migration.
* **Implement**: Added a bounded server-side RCON command console with safe output and error handling; internal-only deployment verification remains pending.

# User Story
As an administrator, I want to manage one or more Minecraft RCON connections, so that server operations can be reached from the existing protected console.
# Acceptance Criteria
- [x] Existing account-manager administrators can list, add, edit, test, enable or disable, and delete RCON server connections.
- [x] Each connection has a unique display name, internal hostname, port, enabled state, and write-only password.
- [x] RCON passwords are encrypted with an authenticated cipher using a deployment-managed master key and are never returned to the browser, audit events, or application logs.
- [x] Updating a connection preserves its password unless an administrator explicitly supplies a replacement.
- [x] Connection host and port pairs must match a deployment-managed exact internal endpoint allowlist, and IP literals are rejected.
- [x] Testing a connection authenticates through the server-side RCON proxy and reports a safe success or failure result.
- [x] Deleting a connection requires explicit confirmation.
- [x] Connection mutations independently recheck administrator authorization and create credential-safe audit events.
- [x] Database changes use a generated versioned Drizzle migration rather than schema push.
# Implementation
The administrator RCON page and server actions manage allowlisted endpoints, preserve write-only passwords, encrypt credentials with connection-bound AES-256-GCM, and emit credential-safe audit events. The `rcon_servers` table is delivered through generated migration `0006_curious_lester.sql`.
# Validation
Verified with RCON validation, encryption, gateway, component, and server-action tests; full workspace tests and type checks; web lint; OKF validation; and a production Next.js build on 2026-08-08. Action tests confirm independent authorization, password preservation, enabled-state rechecks, safe failures, and command audit redaction.

# User Story
As an administrator, I want an RCON console in the portal, so that I can operate internal Minecraft servers without exposing RCON publicly.
# Acceptance Criteria
- [x] Existing account-manager administrators can select an enabled connection and execute an RCON command from the admin UI.
- [x] Browsers never connect to RCON directly; commands pass through the authenticated Next.js server runtime to an internal endpoint.
- [x] Every command independently rechecks administrator authorization and the selected connection's enabled state.
- [x] Commands are length-limited, reject control characters, execute with bounded concurrency and a timeout, and return bounded output.
- [x] Command responses are displayed safely and are not persisted in console history, audit data, or application logs.
- [x] Audit events record the administrator, connection, command verb and digest, success, and duration without recording complete commands or responses.
- [x] Authentication, timeout, and connection failures return safe operator-facing messages without credentials or stack traces.
- [x] The console is keyboard accessible and clearly identifies the selected server.
- [ ] RCON remains internal to the cluster and is not exposed through public ingress or a load balancer.
# Implementation
The client console invokes an authenticated server action that revalidates the enabled allowlisted connection, decrypts its credential only in the server runtime, and executes one bounded command. The gateway limits each process to one operation per server and eight total operations, applies a five-second end-to-end deadline plus bounded cleanup, sanitizes and truncates output, and records keyed command lifecycle audits without command or response content.
# Validation
Application behavior is verified with gateway, validation, component, credential, and server-action tests; full workspace tests and type checks; web lint; OKF validation; and a production Next.js build on 2026-08-08. Deployment-level verification remains pending because this repository has no Minecraft Kubernetes Service, NetworkPolicy, ingress, or load-balancer manifests with which to prove that the RCON port is internal-only.

User authentication begins with an opaque, short-lived, single-use token created for a Discord user. Only a cryptographic hash of the token is persisted. Admin authentication is a separate Keycloak OIDC flow and requires the `minecraft-account-manager-admin` role.
### RCON administration
The administrator console stores one or more internal Minecraft RCON endpoints with write-only AES-GCM-encrypted passwords. Browser requests invoke authenticated server actions; only the Next.js runtime opens RCON TCP connections. Exact deployment-managed endpoint allowlisting prevents the connection registry from becoming an arbitrary internal network proxy. Commands and responses are bounded and ephemeral, while credential-safe audit events retain the operator, server, command verb, keyed digest, outcome, and duration. RCON is exposed only through internal cluster services and never through public ingress.
### Discord bot
The bot creates private login links in response to `/register` and `/account`. Discord user IDs are the canonical Discord identity; mutable usernames are snapshots only. Nickname updates target the deployment guild configured by `DISCORD_GUILD_ID`; the public join button uses `DISCORD_INVITE_URL`.

- Velocity requests use hashed per-server bearer credentials, timestamps, and database-unique request IDs for authentication and replay prevention.
- Session and one-time-code values are random and stored only as hashes.
- Exact IP addresses are sensitive data and require an explicit retention policy before production deployment.
- RCON hostnames and ports must match the deployment allowlist on save and use; passwords never cross the browser trust boundary.
- RCON commands and responses are untrusted, bounded, rendered only as text, and excluded from persistent history and logs.

# RCON administration
The administrator RCON console proxies commands through the Next.js server runtime. Browsers never receive RCON credentials and never open RCON sockets.
## Application configuration
Set `RCON_ALLOWED_ENDPOINTS` to a comma-separated allowlist of exact internal `host:port` pairs:
```text
RCON_ALLOWED_ENDPOINTS=season4.somc.svc.cluster.local:25575
```
IP literals, trailing-dot hostnames, malformed DNS names, and endpoints absent from the allowlist are rejected whenever a connection is saved, tested, or used.
Saved passwords are encrypted with AES-256-GCM and connection-bound authenticated data. By default, domain-separated credential and audit keys are derived from `AUTH_SECRET`. Deployments may instead provide independent 32-byte base64 values through `RCON_CREDENTIAL_KEY` and `RCON_AUDIT_KEY`. Rotating the credential key requires replacing saved RCON passwords.
## Minecraft server configuration
Enable RCON with a high-entropy password supplied through the deployment secret. Expose its port only on an internal `ClusterIP` service. Do not add RCON to an Ingress, NodePort, or public LoadBalancer.
The password entered in the administrator connection form must match the server password. Existing passwords are write-only; leave the replacement field blank when editing unrelated connection settings.
## Security behavior
- Existing account-manager administrator authorization is rechecked for every connection mutation, test, and command.
- Commands are limited to 1,024 UTF-8 bytes and reject control characters.
- Each web process allows one operation per connection and at most eight RCON operations total. Size replica counts with that aggregate ceiling in mind.
- Each complete connect-and-response operation times out after five seconds and tears down the socket; cleanup is independently capped at one second.
- Responses are sanitized and limited to 64 KiB.
- Full commands and responses are not persisted or logged. Audit events contain the command verb and a domain-separated HMAC digest.
- Connection passwords are never selected by page queries or returned to the browser.
RCON is plaintext TCP. Keep it on the cluster network and use network policy or an encrypted tunnel when the network trust model requires stronger isolation.
## Migration
Apply the generated Drizzle migration before deploying the web image:
```bash
npx drizzle-kit migrate
```
Never use `drizzle push` for this schema change.
