+# Orion managed deployment
+
+The authoritative Compose file, release lock, initial preparation script and OPNsense instructions are in `geneticglitch1/homelab-infra`, under `stacks/minecraft/`. Deploy that stack through Komodo on Orion. Do not deploy this repository's root Compose file on top of it.
+
+The release selects Minecraft 26.3, Java 25, Fabric loader 0.19.5, launcher 1.1.2 and exact Modrinth version IDs. Velocity 4.2.0 build 30 consumes TCPShield PROXY protocol; FabricProxy-Lite handles authenticated modern forwarding to the private backend. Offline mode, EasyAuth and the whitelist remain the existing authentication model. Check player UUIDs against a copied world before a migration.
+
+CraftDeck uses `PANEL_MANAGED=true`. Config, mod and file writes, Compose apply and world reset are rejected by the backend. The UI identifies managed mode. Console, player administration, metrics, power controls and backups remain available. These admin controls still have broad authority; managed mode prevents accidental configuration drift and is not a security boundary around the Docker socket.
+
+Persistent state lives in `/opt/minecraft/data/{mc,backups,dashboard,restore}`. CraftDeck mounts their common parent at `/server-data`; this is necessary for Linux rename operations during restore. The deployment lives in `/opt/minecraft/project`, mounted read-only at the same path. Never put a world under a disposable Komodo source checkout.
+
+Build the reviewed source commit on Orion using the infrastructure preparation script. It records Docker's local immutable image ID. Komodo uses that ID with `pull_policy: never`; a restart cannot pull a newer panel. Preparation refuses existing containers or an unknown world. It does not accept the Minecraft EULA or start services.
+
+The panel listens only at `192.168.1.88:8080`, reachable through LAN/VPN and the host firewall. Never forward this port on OPNsense or publish it with NPM. The Docker socket grants host control; keep the panel credentials private.
+
+## Restore and upgrade behavior
+
+A required safety backup failure aborts the operation. A backup request is successful only after a newly created archive passes a complete gzip/tar validation. Power, backup, restore and Compose operations share one reentrant queue within the panel process.
+
+Restores stop both Minecraft and the backup sidecar, validate paths and the managed deployment lock, unpack into a clean staging directory, then move the previous data aside without replacing the bind-mount root. Newer-only files are removed from the active world and retained with the previous data. Failure leaves writers stopped; inspect the recorded restore directory before recovery. Restored files retain the current server directory's ownership.
+
+The panel accepts only backups with the current release lock. For a different release, use a complete stopped backup and the matching deployment/image, following the infrastructure runbook. A world archive does not include the panel database, proxy state or host secrets. Use `cold-backup.sh` for the complete deployment and copy it off Orion.
+
+The root standalone Compose file uses the same restore mount layout. Existing standalone installs must recreate the dashboard with the new mounts and set `PROJECT_DIR` to the absolute host checkout path before using Apply or Restore. `scripts/setup.sh` fills that path for new installs. The manual restore fallback is documented in `scripts/restore.sh`; it stops the panel too, avoiding concurrency with web requests.

-for Fabric. The working path for this stack is **PROXY protocol v2** plus the
-**Proxy Protocol Support** Fabric mod.
 
-## Setup
+The reviewed deployment pins Minecraft 26.3 and Velocity 4.2.0 build 30. The direct Fabric `proxy-protocol-support` mod did not advertise 26.3 support at review time, so it is not used. The old `config/patches` files are legacy and are no longer mounted by the standalone Compose file. Do not combine that legacy direct-server guide with the Velocity deployment.
 
-1. **TCPShield panel** → your backend → enable **Proxy Protocol**.
+OPNsense must preserve the TCPShield source address and permit only the official IPv4 ranges from https://tcpshield.com/v4/. Host DOCKER-USER rules enforce the same restriction before trusted-LAN exceptions. Do not add game port 25565 to unrestricted public ports. Do not expose the backend, RCON, panel or a map port.
-2. **Mods page** → Recommended → add **Proxy Protocol Support** → Apply
-   (or append `proxy-protocol-support` to `MODRINTH_PROJECTS` in `.env` and
-   `docker compose up -d mc`).
-3. Nothing else — the mod's configuration is **enforced automatically on every
-   boot** by `config/patches/patch-set.json` (see below). Restart once after
-   installing so the patch applies:
 
-   ```bash
+The public Minecraft hostname is a DNS-only CNAME to the hostname assigned by TCPShield. An ordinary Cloudflare orange-cloud HTTP proxy is not a Minecraft proxy. Use the public protected hostname even from home; direct LAN joins intentionally fail on the protected proxy port.
-   docker compose restart mc
-   ```
 
-## Verifying it works
+Verify an external join, real player IP, EasyAuth registration, whitelist/UUID continuity and direct-origin rejection before inviting players. Configure TCPShield for the exact protected hostname and backend; account/plan controls and any account-specific verification steps must be completed in its dashboard.
 
-Watch the startup log (`docker compose logs -f mc`). You must see all three:
+Sources: [TCPShield documentation](https://docs.tcpshield.com/), [Velocity forwarding](https://docs.papermc.io/velocity/player-information-forwarding/), [OPNsense NAT](https://docs.opnsense.org/manual/nat.html).
-
-```
-Proxy Protocol Support is enabled!
-TCPShield integration enabled! Fetching official IPs...
-Successfully added 2 TCPShield IPs to the trusted proxy list.
-```
-
-Then join through your TCPShield domain — the console shows your **real IP**, and
-`docker compose ps` shows `mc` **healthy**.
-
-## How the config is managed (don't hand-edit!)
-
-The mod rewrites `config/proxy_protocol_support.json` at every startup, which
-silently clobbers hand edits. Instead, the server image applies
-`config/patches/patch-set.json` from this repo **before every server start**,
-enforcing:
-
-| Setting | Value | Why |
-|---|---|---|
-| `enableProxyProtocol` | `true` | decode PROXY protocol headers |
-| `whitelistTCPShieldServers` | `true` | auto-fetch TCPShield's proxy IP ranges — no hardcoding, survives their infra changes |
-| `proxyServerIPs` | `127.0.0.1` | (TCPShield's ranges are added automatically at runtime) |
-| `directAccessIPs` | localhost (`127.0.0.1`, `::1`) + private ranges (`10/8`, `172.16/12`, `192.168/16`) | container healthcheck + LAN/panel access |

-To change a value, edit the patch file in the repo and `docker compose up -d mc`.
-
-**First-boot note:** on a brand-new install the mod's config file doesn't exist
-yet when patches run, so the very first boot uses mod defaults; every boot after
-that is patched. One `docker compose restart mc` after first install settles it.
-
-## Security model
-
-PROXY protocol headers carry no signature, so anyone who finds your raw server IP
-could spoof client IPs — the mod prevents this with default-deny:
-
-- PROXY headers are only accepted from **TCPShield's published ranges** (auto-fetched)
-- Direct, header-less connections are only accepted from **localhost + LAN**
-- Everything else → `REJECTED unauthorized direct connection` in the log
-
-So occasional `REJECTED` lines from random public IPs are the wall working —
-that's scanner bots hitting your raw IP and bouncing. A `REJECTED ... /0:0:0:0:0:0:0:1`
-(IPv6 localhost) every few seconds means the container healthcheck is being
-blocked — that's exactly what the `::1` entry in the patch prevents; if you see
-it, the patch didn't apply (check `docker compose logs mc | head -50`).
-
-For belt-and-braces, also enable TCPShield's Advanced Firewall (panel → Network →
-Firewall), and consider host-firewalling port 25565 to TCPShield's ranges
-(`curl tcpshield.com/v4`) once everything works.
-
-## Gotchas
-
-- **Friends must connect via the TCPShield domain** — direct-IP connections from
-  outside your LAN are rejected by design once this is active.
-- If real players start bouncing with `REJECTED`, TCPShield may have changed
-  their IP ranges *and* the auto-fetch failed at boot — restart the server so it
-  re-fetches.

-## Upgrading Minecraft (e.g. 26.2 → 26.3)
+For Orion, edit `homelab-infra/stacks/minecraft/release-lock.json` and Compose together. Verify the Minecraft, Java, Fabric, mod and Velocity compatibility matrix against upstream releases. Build and test the exact CraftDeck commit; record its immutable local image ID. No production setting should use `latest` without an image digest or an unversioned mod slug.
 
-1. **Configuration** page → change `Minecraft version` → **Save**
+Before an update, make a complete stopped backup with the infrastructure `cold-backup.sh`, copy it off-host, and verify a restore in an isolated instance. Start the candidate on a disposable world and a copy of existing state first. Confirm authentication UUIDs, whitelist, registration, proxy IP forwarding and resource headroom.
-2. **Apply** with *"Take a safety backup first"* enabled
-3. The server container is recreated: the new server jar, a matching Fabric loader, and
-   fresh builds of every managed mod are downloaded automatically
 
-If a managed mod has no build for the new version yet, the server won't start — check
+After approval, stop through Komodo, materialize the reviewed files, preserve the previous project/lock and image, and update the world's `.deployment-lock.json` to the candidate release. Do not use the initial preparation script to overwrite an existing installation. Deploy manually and run the acceptance checks in the infrastructure README.
-the Console page for which one, remove it from the Mods page (or wait a few days), and
-Apply again. Worlds upgrade forward automatically; **there is no downgrade** — that's
-what the safety backup is for.
 
-Command-line equivalent:
+Rollback means restoring the matching complete data backup, panel database, secrets, proxy configuration and previous image/lock. Downgrading a version setting against a newer world is not a rollback. Managed panel restores deliberately refuse mismatched release locks.
 
-```bash
+For the standalone setup, `PROJECT_DIR` must equal the absolute host checkout. Update the explicit image, Minecraft, loader and Modrinth pins together. Config/mod Apply takes a required backup and aborts on failure. Newly added unversioned mod slugs remain a standalone convenience; pin their reviewed Modrinth version IDs before treating that installation as a locked release.
-sed -i 's/^MC_VERSION=.*/MC_VERSION=26.3/' .env
-docker exec mc-backup backup now
-docker compose up -d mc
-```
-
-## Updating mods only
-
-Mods page → **Update all & restart**. (Any server restart re-resolves managed mods.)
-
-## Updating the panel / images
-
-```bash
-git pull
-docker compose pull          # new itzg server + backup images
-docker compose build dashboard
-docker compose up -d
-```
-
-## Snapshots / release candidates
-
-`MC_VERSION` accepts any version the launcher knows (`26.3-rc-1`, `26.3-snapshot-3`…).
-Mods rarely support snapshots — expect to trim the mod list if you try them.
