feat(node): node hardening — mTLS, hashed+zstd reconcile transport, per-node net metrics (#5382)

* fix(api-docs): document clientIpsByGuid route

Restores a green `go test ./...` baseline: TestAPIRoutesDocumented
flagged POST /panel/api/clients/clientIpsByGuid (added in 9385b6c6)
as undocumented in endpoints.ts.

* test(node): characterize current node TLS + API auth behavior

Phase 0 regression net for the mTLS work. These pass on unchanged
production code and lock the pre-mTLS contracts so later phases can be
proven additive:

- tlsConfigForNode: skip -> InsecureSkipVerify (no VerifyConnection);
  pin -> VerifyConnection installed.
- checkAPIAuth: bearer match -> Next + api_authed; unauthenticated ->
  401 (XHR) / 404; valid session -> Next.
- panel HTTPS listener with no ClientAuth accepts a client that presents
  no client certificate (the browsers-keep-working invariant).

* feat(crypto): node-auth CA + client-cert minting (TDD)

Stdlib-only ECDSA P-256 helpers for the node mTLS work:
- GenerateNodeCA: self-signed CA (IsCA, CertSign, path len 0)
- IssueClientCert: client-auth leaf (ExtKeyUsageClientAuth) signed by CA
- LoadCAFromPEM: parse a CA cert+key for issuing / trust-pool building

Tests assert the contract (leaf verifies against the issuing CA with
ExtKeyUsageClientAuth), seen failing on the assertion before impl.

* feat(node): lazy node mTLS CA + client cert in settings (TDD)

SettingService gains opt-in mTLS material, all stored as Setting rows
with empty defaults and kept out of entity.AllSetting (so private keys
never reach the settings UI/export):
- EnsureNodeMtlsCA: mint+persist the node-auth CA once, reuse thereafter
- EnsureMasterClientCert: issue the master client cert from the CA, idempotent
- NodeMtlsClientCAPool: ClientCAs trust pool for the listener; nil when
  unconfigured so the no-mTLS path is unchanged

Tests assert idempotency and that the client cert verifies against the CA
for client auth; seen failing on the assertion before impl.

* feat(node): mtls client TLS config + master-cert provider (TDD)

tlsConfigForNode gains an 'mtls' branch that presents the master client
certificate and verifies the node server against system roots (no
InsecureSkipVerify, no custom RootCAs). The cert is supplied via an
injected MasterClientCertProvider so runtime need not import service;
it fails closed when unconfigured. skip/pin contracts unchanged.

* feat(node): allow tokenless mtls nodes in remote do() (TDD)

mtls nodes authenticate with a client certificate, so the bearer token
becomes optional for them: do() no longer rejects an empty ApiToken when
TlsVerifyMode is mtls, and the Authorization header is omitted when no
token is set. Every other mode still requires a token (regression kept).

* feat(node): authenticate verified client certs in checkAPIAuth (TDD)

A completed mTLS handshake (non-empty r.TLS.VerifiedChains) now
authenticates an API request, equivalent to a valid bearer token, and
sets api_authed so the CSRF middleware lets cert-authed mutations
through. Bearer/session/reject paths unchanged. The accept-path assert
was mutation-checked (guard flipped -> test red -> reverted).

* feat(node): opt-in mTLS on the panel listener (TDD; mutation-checked)

web.go now applies VerifyClientCertIfGiven + ClientCAs to the HTTPS
listener when a node trust CA is configured, and wires the master client
cert provider for outbound mtls calls. With no CA the listener is
byte-identical to before (browsers unaffected).

applyNodeMtls is covered end-to-end: no-cert client handshakes (browsers
keep working), a CA-signed client cert verifies, a foreign-CA cert is
rejected at the handshake. Mutation-checked:
- RequireAndVerifyClientCert -> no-cert client rejected (red) -> reverted
- drop ClientCAs -> master cert no longer trusted (red) -> reverted

* feat(node): accept mtls verify-mode + CA reveal endpoint (TDD)

- model.Node.TlsVerifyMode validator now accepts 'mtls'
- normalize() preserves mtls and requires the node scheme to be https
  (fail closed), instead of clamping mtls back to verify
- NodeService.NodeMtlsCaCert + POST /panel/api/nodes/mtls/ca return this
  panel's node-auth CA cert (public) to paste into a node, minting the CA
  + master client cert on first call
- endpoints.ts documents the new route (doc-sync test)

No model column added (enum is a string), so no migration/codegen.

* feat(node): node mTLS UI + trust-CA setter (TDD)

Backend:
- NodeService.SetNodeMtlsTrustCA + POST /panel/api/nodes/mtls/trustCA
  store the CA this panel trusts for incoming node-API client certs
  (validates PEM, empty clears); applied on next restart
- endpoints.ts + regenerated openapi.json document both mtls routes

Frontend:
- node form: 'mtls' TLS-verify option + setup hint (zod enum updated)
- Nodes page 'Node mTLS' card: copy this panel's CA, and paste/save the
  trusted parent CA
- en-US i18n keys (other locales fall back to en-US)

Gates green: go build (native+windows), vet, go test ./...; frontend
typecheck, lint, vitest (541).

* style(node): gofmt web_mtls_test doc comment

* feat(node): hashed+zstd reconcile transport (TDD, negotiated, mixed-version safe)

Adds an integrity + compression envelope to node config pushes:
- internal/util/wirecodec: shared zstd codec (bomb-capped decode) +
  SHA-256 hashing + the header/capability constants
- Remote.do(): always attaches X-Config-Sha256 of the uncompressed body;
  zstd-compresses only when the node advertised support (learned from its
  X-3x-Node-Caps response header) and the body is >=1KiB
- ConfigEnvelopeMiddleware on /panel/api: advertises the cap, decompresses
  and verifies the hash (handler not invoked on mismatch) before binding

Mixed-version safe: old nodes never advertise the cap -> plain bodies;
the hash header is verify-if-present so any panel/node mix interoperates
(existing reconcile tests stay green). klauspost/compress promoted to a
direct dep. Hash-mismatch reject was mutation-checked (compare defeated
-> test red -> reverted).

* feat(node): per-node network throughput metrics (TDD)

The node status response already carries gopsutil netIO.up/down (summed
non-virtual interfaces), so no node-side change is needed:
- probe() parses netIO.up/down into HeartbeatPatch.NetUp/NetDown
- Node gains net_up/net_down columns (AutoMigrate); UpdateHeartbeat
  persists them and appends netUp/netDown to the per-node metric history
- NodeMetricKeys whitelists netUp/netDown so the history endpoint serves them
- NodeHistoryPanel renders Net Up/Down sparklines (KB/s, no 0-100 clamp)
- regenerated frontend types + openapi.json for the new Node fields

* feat(node): move node mTLS controls into a toolbar button + modal

The Node mTLS panel was an always-visible card cluttering the nodes
page. Replace it with a 'Node mTLS' button beside 'Add node' that opens
a modal with the same copy-CA + trusted-parent-CA controls; the modal
closes on a successful save. No backend/i18n changes.

* i18n(node): translate mTLS + net-metrics keys for all locales

Adds the node mTLS strings (tlsMtls, mtlsFormHint, mtls.* dialog + the
saveMtls toast) and the netUp/netDown chart labels to all 12 non-English
catalogs (ar, es, fa, id, ja, pt, ru, tr, uk, vi, zh-CN, zh-TW), matching
each catalog's existing terminology. Technical tokens (mTLS/TLS/CA/API/
KB/s) kept verbatim.

* fix(node): address Copilot review on node-hardening PR

- setting_mtls: fail closed on a half-present CA/master-cert pair instead of
  silently regenerating (which would rotate the CA and break fleet trust).
- config_envelope: reject non-zstd Content-Encoding on the envelope path
  rather than hashing/forwarding a still-encoded body to the handler.
- node mTLS: support tokenless mTLS end-to-end — apiToken is now
  required_unless tlsVerifyMode=mtls (model) with matching conditional
  validation in NodeFormSchema, so the runtime allowance is actually reachable.
- NodesPage: add a catch block to onSaveTrustCa so save failures surface.

+              reaching out!"), no hype, and no apologies on behalf of the
+              project.
+            - Lead with the answer or conclusion in the first sentence; put
+              supporting detail after it.
+            - Use GitHub Markdown deliberately: short paragraphs, bullet or
+              numbered lists for steps, fenced code blocks for commands,
+              configs, and logs, backticks for file paths, flags, and setting
+              names. No headings in short comments.
+            - Be precise about certainty: distinguish what you CONFIRMED in
+              the source (name the file, e.g. internal/web/service/setting.go)
+              from what you infer. Never present a guess as fact, and never
+              promise fixes, timelines, or releases.
+            - When information is missing, request it as a short numbered list
+              of exactly what is needed and why (e.g. panel version from
+              `x-ui`, OS, install method, relevant logs).
+            - One comment only; keep it as short as completeness allows.
+            - End with one italic line stating the reply was generated
+              automatically and a maintainer may follow up.

Two runtime paths consume it: the **inbounds page** and the **clients page** subscription links (`/panel/api/clients/subLinks/:subId` → backend `GetSubs`); exercise both.
 - **Vite is pinned to an exact version** (no `^`) in `frontend/package.json` — currently `8.0.16` — so local, CI, and release builds resolve identically. Bump it deliberately and verify both `npm run dev` and `npm run build` afterward.

+## Testing
+
+Tests live next to the code (`foo.go` ↔ `foo_test.go`); frontend specs and golden fixtures live in `frontend/src/test/`.
+
+### Go conventions
+
+- **Stdlib `testing` only** — no testify. Table-driven with `t.Run` subtests and `t.Helper()` on helpers.
+- **Assert the contract, not internals.** Pin the exact value / typed error / emitted string — not `err != nil` or `len > 0`. A test that still passes when the behavior is broken is worse than no test.
+- **Real dependencies over mocks.** Get a throwaway DB with `database.InitDB(filepath.Join(t.TempDir(), "x-ui.db"))` + `t.Cleanup(func() { _ = database.CloseDB() })` (Windows-safe), and use `httptest` servers for HTTP. The `internal/sub` suite's `initSubDB(t)` is the template.
+
+### Running
+
+| Goal | Command |
+|------|---------|
+| Standard run | `go test ./...` |
+| Hygiene — data races + order-dependence | `go test -race -shuffle=on -count=1 ./...` (`-race` needs the C compiler from Prerequisites) |
+| Coverage gaps | `go test -coverprofile=cov.out ./<pkg>/... && go tool cover -func=cov.out` |
+| Fuzz a parser briefly | `go test -run '^$' -fuzz 'FuzzName$' -fuzztime=30s ./<pkg>/...` |
+
+Frontend: `cd frontend && npm run test` (vitest), or `npm run test -- --coverage`.
+
+### Property and fuzz tests
+
+Input-heavy or pure logic (link builders, parsers, decoders) is also covered by **property tests** (`pgregory.net/rapid`) and **native fuzz targets** (`go test -fuzz`). A fuzz target's **seed corpus** (its inline `f.Add` cases plus any `testdata/fuzz` entries) runs as ordinary subtests under a plain `go test` — no `-fuzz` flag needed — so CI's normal test job exercises the seeds; the time-boxed *fuzzing* exploration (`-fuzz=...`) runs separately as the `fuzz-smoke` job.
+
+### Mutation testing (optional, manual)
+
+[gremlins](https://github.com/go-gremlins/gremlins) checks whether tests actually fail when the code is mutated — a surviving (`LIVED`) mutant means a weak test. It is **slow**, so run it **scoped per package**, never repo-wide or per-commit:
+
+```bash
+go install github.com/go-gremlins/gremlins/cmd/gremlins@latest
+gremlins unleash ./internal/sub/
+gremlins unleash -E 'server\.go|xray\.go|inbound\.go|client_bulk\.go|inbound_traffic\.go|.*_postgres_test\.go' ./internal/web/service/
+```
+
+Treat each survivor as one of: a weak test (strengthen it), dead code (remove it), or an equivalent mutant (unkillable — leave it). Don't write a test purely to kill a mutant if it doesn't reflect real behavior.
+
+CI runs this for you nightly (and on demand) via `.github/workflows/mutation.yml` — scoped per package, results uploaded as artifacts. It is **informational**, not a gate (no thresholds), so check the reports when hardening a suite rather than waiting for a red build.
+
+### CI
+
+`.github/workflows/ci.yml` runs per PR: `go-test` (with `-shuffle -count=1`), a `race` job (`-race -shuffle -count=1`), a `fuzz-smoke` job on the critical parsers, and the frontend `typecheck`/`lint`/`test`/`build`. Snapshots are regression guards — regenerate them (`npx vitest run -u`) only for intentional output changes, never to make a red test green.

+# Cloud deployment & golden images
+
+Tooling to ship the 3x-ui panel as a cloud image or via unattended install,
+with **per-instance credentials generated on first boot** (never `admin/admin`,
+never a shared session secret). Everything here supports **amd64 and arm64**.
+
+| Path | What it is | Use when |
+| --- | --- | --- |
+| [`cloud-init/`](cloud-init/) | Generic cloud-init user-data (unattended `install.sh`) | Any cloud, no image build |
+| [`packer/`](packer/) | Packer build → AWS AMI + qcow2/raw | Reusable / Marketplace images |
+| [`lightsail/`](lightsail/) | Launch script + snapshot builder | Amazon Lightsail |
+| [`firstboot/`](firstboot/) | First-boot unit + script that mints per-instance creds | Used by the Packer/Lightsail images |
+| [`marketplace/aws/`](marketplace/aws/) | AWS Marketplace submission checklist | Publishing an EC2 AMI |
+| [`marketplace/hetzner/`](marketplace/hetzner/) | Hetzner Cloud notes | Hetzner deployments |
+| [`test/`](test/) | Container smoke tests | Verifying the install/firstboot paths |
+
+## Two models
+
+- **Non-interactive install (cloud-init):** `install.sh` runs unattended when
+  `XUI_NONINTERACTIVE=1` or stdin is not a TTY. Each instance installs and
+  configures itself with random credentials. See [`cloud-init/README.md`](cloud-init/README.md).
+- **Golden image (Packer):** the image contains the panel but **no DB and no
+  secrets**; `firstboot` generates unique credentials on first boot. See
+  [`packer/README.md`](packer/README.md).
+
+## Unattended install knobs
+
+`install.sh` reads these env vars in non-interactive mode (all optional; unset ⇒
+secure random / default):
+
+`XUI_USERNAME`, `XUI_PASSWORD`, `XUI_PANEL_PORT`, `XUI_WEB_BASE_PATH`,
+`XUI_SSL_MODE` (`none`|`ip`|`domain`, default `none`), `XUI_DOMAIN`,
+`XUI_ACME_EMAIL`, `XUI_ACME_HTTP_PORT` (ACME HTTP-01 listener port, default `80`),
+`XUI_SSL_IPV6` (optional IPv6 address to add to an `ip`-mode cert),
+`XUI_SERVER_IP` (fallback IP for the displayed access URL when auto-detection fails),
+`XUI_DB_TYPE` (`sqlite`|`postgres`), `XUI_DB_DSN`.
+
+The resulting credentials are written to `/etc/x-ui/install-result.env` (mode 600).

+# 3x-ui via cloud-init (generic, no golden image)
+
+This is the **secondary** deployment path: a single [`cloud-init.yaml`](cloud-init.yaml)
+user-data file that installs 3x-ui non-interactively on a fresh Ubuntu/Debian
+VM and generates **unique random credentials per instance**. Use it when you do
+not want to build a golden image — it works on any cloud-init platform.
+
+> For AWS Marketplace / reusable images, use the Packer build in
+> [`../packer/`](../packer/) instead.
+
+## How it works
+
+1. The VM boots a stock Ubuntu/Debian cloud image.
+2. cloud-init writes and runs `/opt/xui-bootstrap.sh`, which exports
+   `XUI_NONINTERACTIVE=1` and pipes the project's `install.sh` into `bash`.
+3. `install.sh` runs end-to-end with **zero prompts**, picking secure random
+   values for any credential you didn't pin.
+4. The generated credentials are written to `/etc/x-ui/install-result.env`
+   (mode 600), echoed to the **serial console**, and appended to `/etc/motd`.
+
+Retrieve them after boot with either:
+
+```bash
+sudo cat /etc/x-ui/install-result.env     # over SSH
+```
+
+…or read the provider's **serial console** output (handy before you have SSH).
+
+## Customising
+
+Edit the `export XUI_*` lines inside the `write_files` block of
+[`cloud-init.yaml`](cloud-init.yaml). All knobs are optional; unset ⇒ random/secure default.
+
+| Env var | Default | Meaning |
+| --- | --- | --- |
+| `XUI_SSL_MODE` | `none` | `none` (plain HTTP), `ip` (Let's Encrypt IP cert), `domain` |
+| `XUI_USERNAME` | random | Admin username |
+| `XUI_PASSWORD` | random | Admin password |
+| `XUI_PANEL_PORT` | random high port | Panel listen port |
+| `XUI_WEB_BASE_PATH` | random | Panel base path (obscures the URL) |
+| `XUI_DOMAIN` | — | Required when `XUI_SSL_MODE=domain` |
+| `XUI_ACME_EMAIL` | — | Let's Encrypt account email (domain mode) |
+| `XUI_DB_TYPE` / `XUI_DB_DSN` | `sqlite` | Set `postgres` + DSN to use PostgreSQL |
+
+> **TLS note:** `none` serves the panel over plain HTTP on a random high port —
+> fine behind a reverse proxy or an SSH tunnel, but put TLS in front of it before
+> exposing the panel publicly. `domain` mode needs a public DNS A record pointing
+> at the box and port 80 reachable at install time.

+# 3x-ui on Amazon Lightsail
+
+Two self-service ways to run 3x-ui on Lightsail, both producing **unique
+per-instance credentials** (never `admin/admin`, never a shared secret).
+
+> **Reality check.** The Lightsail *blueprint* list (WordPress, LAMP, GitLab…)
+> is curated by AWS — you **cannot** self-publish your panel there, and Lightsail
+> **cannot** launch from an arbitrary EC2 AMI. What you *can* do yourself is the
+> two paths below. (For a public AWS listing you'd use the EC2 **AMI** +
+> Marketplace path in [`../marketplace/aws/`](../marketplace/aws/), which is a
+> different product from Lightsail.)
+
+---
+
+## Path A — launch script (simplest, self-service)
+
+Install on a fresh instance at creation time. No image to build.
+
+1. **Create instance** → platform **Linux/Unix** → blueprint **OS Only → Ubuntu 24.04**.
+2. **Add launch script** → paste [`launch-script.sh`](launch-script.sh).
+3. Create the instance.
+4. After it boots, read the credentials:
+   ```bash
+   ssh ubuntu@<public-ip> 'sudo cat /etc/x-ui/install-result.env'
+   ```
+5. **Open the panel port** (see the firewall note below) and log in.
+
+CLI equivalent:
+
+```bash
+aws lightsail create-instances \
+  --instance-names my-3xui \
+  --availability-zone eu-central-1a \
+  --blueprint-id ubuntu_24_04 \
+  --bundle-id small_3_0 \
+  --user-data file://deploy/lightsail/launch-script.sh \
+  --region eu-central-1
+```
+
+By default the panel uses a **random** high port (in `install-result.env`). To
+pin a known port so you can pre-open it, set `export XUI_PANEL_PORT=54321` inside
+`launch-script.sh`.
+
+---
+
+## Path B — reusable snapshot (your own "ready image")
+
+Build a Lightsail **snapshot** once; launch as many instances from it as you
+like, each generating its own credentials on first boot (the golden-image model).
+
+```bash
+deploy/lightsail/build-snapshot.sh --region eu-central-1 --panel-port 54321
+```
+
+What it does: launches a temporary Ubuntu instance with
+[`snapshot-userdata.sh`](snapshot-userdata.sh) (installs the panel, **no DB**,
+enables the first-boot unit), strips all state via the shared
+[`cleanup.sh`](../packer/scripts/cleanup.sh), then snapshots and deletes the
+build instance. Requires `awscli`, `jq`, `ssh` and Lightsail permissions.
+
+Launch instances from the snapshot:
+
+```bash
+aws lightsail create-instances-from-snapshot \
+  --instance-snapshot-name 3x-ui-ubuntu-24.04-<stamp> \
+  --instance-names my-3xui-1 --bundle-id small_3_0 \
+  --availability-zone eu-central-1a --region eu-central-1
+```
+
+Each launched instance runs `x-ui-firstboot` and writes its unique credentials to
+`/etc/x-ui/credentials.txt` + `/etc/motd`. With `--panel-port` the port is the
+same across instances (only the credentials differ), so you can pre-open it.
+
+> Lightsail snapshots are **private to your AWS account** (and region). To use one
+> elsewhere you can export it to EC2 (`aws lightsail export-snapshot`) and share
+> the resulting AMI.
+
+---
+
+## Lightsail firewall note (important)
+
+Lightsail's per-instance firewall only opens **22 / 80 / 443** by default. The
+panel runs on a different port, so you must open it:
+
+- Console: instance → **Networking → IPv4 Firewall → Add rule** (TCP, the panel port).
+- CLI:
+  ```bash
+  aws lightsail open-instance-public-ports --region eu-central-1 \
+    --instance-name my-3xui \
+    --port-info fromPort=54321,toPort=54321,protocol=TCP
+  ```
+
+The panel port is in `/etc/x-ui/install-result.env` (Path A) or
+`/etc/x-ui/credentials.txt` (Path B), or fixed via `--panel-port` / `XUI_PANEL_PORT`.

+# build-snapshot.sh — build a reusable Amazon Lightsail snapshot of 3x-ui.
+#
+# Flow (mirrors the Packer golden-image model, via the Lightsail API):
+#   1. create an Ubuntu Lightsail instance with snapshot-userdata.sh
+#      (installs the panel, NO database, enables the first-boot unit)
+#   2. wait for provisioning, then (optionally) pin a known panel port and run

+#   4. delete the build instance (unless --keep-instance)
+#
+# Every instance you later launch from the snapshot generates its OWN unique
+# credentials on first boot (see deploy/firstboot/). The snapshot is private to
+# your AWS account.

+# Publishing 3x-ui to the AWS Marketplace (AMI)
+
+This is the checklist for turning the Packer-built AMI into an AWS Marketplace
+listing. It assumes you have already built an AMI with
+[`../../packer/`](../../packer/) (locally or via `.github/workflows/image.yml`).
+
+> Do **not** commit AMI IDs, AWS account numbers, or credentials. The AMI ID is
+> printed to the workflow job summary at build time.
+
+## 1. Seller registration (one-time)
+
+1. Sign in to the [AWS Marketplace Management Portal](https://aws.amazon.com/marketplace/management/)
+   with the AWS account that will own the listing.
+2. Complete **seller registration** (legal entity, bank, tax interview). Required
+   before any product can be submitted.
+
+## 2. Build a compliant AMI
+
+Build in the seller account (or share the AMI into it):
+
+```bash
+cd deploy/packer
+packer init .
+# amd64
+packer build -only='amazon-ebs.x-ui' \
+  -var 'xui_version=vX.Y.Z' -var 'xui_arch=amd64' -var 'instance_type=t3.small' -var 'region=eu-central-1' .
+# arm64 (Graviton)
+packer build -only='amazon-ebs.x-ui' \
+  -var 'xui_version=vX.Y.Z' -var 'xui_arch=arm64' -var 'instance_type=t4g.small' -var 'region=eu-central-1' .
+```
+
+You can list both AMIs (amd64 + arm64) as architectures of a single Marketplace
+product, or as separate products.
+
+The image already satisfies the Marketplace AMI policies enforced by `harden.sh`
++ `cleanup.sh`:
+
+- ✅ `PasswordAuthentication no`, `PermitRootLogin prohibit-password`
+- ✅ no default OS account passwords (all locked)
+- ✅ no baked `authorized_keys`, no SSH host keys (regenerated on boot)
+- ✅ base OS = current Ubuntu 24.04 LTS, patched at build time
+- ✅ no application default credentials — the panel admin is generated on first
+  boot on a random high port (no `admin/admin`, no shipped `x-ui.db`)
+
+## 3. Run the self-service AMI scan
+
+1. In the Management Portal: **Server products → AMIs → Upload/scan an AMI**.
+2. Share the AMI with the AWS Marketplace scanning account when prompted
+   (the portal gives you the exact account id and the `modify-image-attribute`
+   command, or share it from the EC2 console).
+3. Start the scan. It checks SSH config, default credentials, open ports, and
+   for malware. Fix any finding and re-scan.
+
+Common scan findings and where they're handled:
+
+| Finding | Fix (already in the build) |
+| --- | --- |
+| Password authentication enabled | `harden.sh` sshd drop-in |
+| Root login with password | `harden.sh` `PermitRootLogin prohibit-password` |
+| Default user password set | `harden.sh` `passwd -l` on all accounts |
+| Authorized keys present | `cleanup.sh` removes them |
+| Out-of-date packages | base image is the latest LTS; `provision.sh` runs `apt-get update` |
+
+## 4. Create the product (limited / private first)
+
+1. **Server products → Create new product → AMI** (or AMI + CloudFormation).
+2. Add title, description, categories, pricing (free or paid), regions, the AMI
+   id, recommended instance types, and the **usage instructions** (tell buyers
+   to read `/etc/x-ui/credentials.txt` / MOTD after first boot for the generated
+   admin login, then change the password).
+3. Submit as a **Limited** (private) listing first. AWS publishes it with
+   restricted visibility so only your account / allow-listed accounts see it.
+
+## 5. Preview & launch test
+
+1. From the limited listing, **subscribe and launch** a test instance.
+2. SSH in, `sudo cat /etc/x-ui/credentials.txt`, open the panel URL, log in,
+   confirm the panel works and the credentials are unique to that instance.
+3. Launch a second instance and confirm its credentials differ (no shared
+   secrets).
+
+## 6. Go public
+
+1. Once the scan passes and the preview looks correct, request **public
+   visibility** (move from Limited to Public) in the listing.
+2. AWS does a final review before the listing goes live.

+# 3x-ui on Hetzner Cloud
+
+Hetzner Cloud does **not** have a third-party image marketplace the way AWS does.
+There are two practical ways to ship 3x-ui on Hetzner.
+
+## Option A — cloud-init (recommended, no image build)
+
+Use the generic user-data from [`../../cloud-init/`](../../cloud-init/). It installs
+3x-ui non-interactively and generates unique per-instance credentials.
+
+Web console: **Create Server → Cloud config** → paste
+[`deploy/cloud-init/cloud-init.yaml`](../../cloud-init/cloud-init.yaml).
+
+CLI:
+
+```bash
+hcloud server create \
+  --name xui-1 \
+  --type cx22 \
+  --image ubuntu-24.04 \
+  --user-data-from-file deploy/cloud-init/cloud-init.yaml
+```
+
+After boot, fetch the generated credentials:
+
+```bash
+ssh root@<server-ip> 'cat /etc/x-ui/install-result.env'
+```
+
+## Option B — snapshot from the qcow2 / a configured server
+
+Hetzner lets you create a **snapshot** of a running server and launch new
+servers from it. Two ways to get there:
+
+1. **From the Packer qcow2:** Hetzner does not allow direct qcow2 upload via the
+   normal API, but you can boot a server, write the image to its disk in rescue
+   mode, then take a snapshot — or simply use Option A, which needs no image.
+2. **From a configured server:** spin up a server, install via cloud-init
+   (Option A), verify, then **delete `/etc/x-ui/x-ui.db` and the first-boot
+   sentinel** before snapshotting so clones regenerate their own credentials:
+
+   ```bash
+   systemctl stop x-ui
+   rm -f /etc/x-ui/x-ui.db /etc/x-ui/.firstboot-done /etc/x-ui/credentials.txt
+   # re-enable first-boot regeneration if you installed via Packer:
+   systemctl enable x-ui-firstboot 2>/dev/null || true
+   ```
+
+   > ⚠️ If you snapshot a server **with** its `x-ui.db`, every clone shares the
+   > same admin credentials and session secret. Always remove the DB first.
+
+## "App"-style listing
+
+Hetzner's curated apps live in the community repo
+[`github.com/hetznercloud/apps`](https://github.com/hetznercloud/apps): each app
+is essentially a documented cloud-init config plus metadata. To propose 3x-ui as
+a Hetzner app, follow that repo's contribution pattern and base the app's
+cloud-config on [`deploy/cloud-init/cloud-init.yaml`](../../cloud-init/cloud-init.yaml).

+# 3x-ui golden image (Packer)
+
+Builds a cloud image with the 3x-ui panel pre-installed but **not configured**:
+the image ships with **no database and no credentials**, and generates a unique
+admin account on first boot. This is the **primary** path for AWS Marketplace
+and any reusable image.
+
+Two sources, one build:
+
+| Source | Output | For |
+| --- | --- | --- |
+| `amazon-ebs` | AWS AMI | AWS / Marketplace |
+| `qemu` | `qcow2` (+ `raw`) | Hetzner, DigitalOcean, Vultr, GCP, Azure, Oracle, bare metal |
+
+Both sources build for **`amd64` and `arm64`** (select with `-var xui_arch=...`).
+
+## Why no baked DB
+
+3x-ui seeds a hardcoded `admin/admin` user and generates its session secret +
+panel GUID the first time it starts. If an image shipped an initialized
+`x-ui.db`, **every clone would share the same credentials and secret**. So the
+build deliberately:
+
+- installs the panel binary + systemd unit but **never starts it** and **never
+  creates a DB** (`scripts/provision.sh`);
+- wipes any stray DB/credentials/host-keys at the end (`scripts/cleanup.sh`);
+- enables `x-ui-firstboot.service`, which on first boot resets settings, sets a
+  random username/password on a random high port, regenerates the secret/GUID,
+  and writes the credentials to `/etc/x-ui/credentials.txt` + `/etc/motd`
+  (`deploy/firstboot/`).
+
+## Prerequisites
+
+- [Packer](https://developer.hashicorp.com/packer) ≥ 1.9
+- For `qemu` amd64: `qemu-system-x86`, `qemu-utils` (and `/dev/kvm` for acceptable speed)
+- For `qemu` arm64: `qemu-system-arm`, `qemu-efi-aarch64`, `qemu-utils` — best built on an
+  arm64 host (native KVM); cross-building from x86 works but uses slow TCG emulation
+- For `amazon-ebs`: AWS credentials with EC2 build permissions (arm64 builds on a Graviton
+  instance such as `t4g.small`)
+
+```bash
+cd deploy/packer
+packer init .
+packer fmt -check .      # formatting
+packer validate .        # both sources
+```
+
+## Build
+
+Build a specific release (recommended) or `latest`:
+
+```bash
+# amd64 qcow2 (no cloud account needed)
+packer build -only='qemu.x-ui' -var 'xui_version=v3.3.1' -var 'xui_arch=amd64' .
+
+# arm64 qcow2 (run on an arm64 host for native KVM)
+packer build -only='qemu.x-ui' -var 'xui_version=v3.3.1' -var 'xui_arch=arm64' .
+
+# amd64 AWS AMI
+packer build -only='amazon-ebs.x-ui' \
+  -var 'xui_version=v3.3.1' -var 'xui_arch=amd64' -var 'instance_type=t3.small' -var 'region=eu-central-1' .
+
+# arm64 AWS AMI (Graviton)
+packer build -only='amazon-ebs.x-ui' \
+  -var 'xui_version=v3.3.1' -var 'xui_arch=arm64' -var 'instance_type=t4g.small' -var 'region=eu-central-1' .
+```
+
+Outputs (per arch):
+- `output-qemu/3x-ui-ubuntu-24.04-<arch>.qcow2` and `.raw`
+- the AMI id (also recorded in `packer-manifest.json`)
+
+If `/dev/kvm` is unavailable, add `-var 'qemu_accelerator=tcg'` (much slower).
+
+## Key variables
+
+See [`variables.pkr.hcl`](variables.pkr.hcl) for the full list.
+
+| Variable | Default | Notes |
+| --- | --- | --- |
+| `xui_version` | `latest` | Release tag to install, e.g. `v3.3.1` |
+| `xui_arch` | `amd64` | `amd64` or `arm64` (derives the base AMI / cloud image) |
+| `region` | `eu-central-1` | AWS region (amazon-ebs) |
+| `instance_type` | `t3.small` | EC2 build instance — must match the arch (`t4g.small` for arm64) |
+| `qemu_accelerator` | `kvm` | `kvm` or `tcg` |
+| `qemu_cpu` | `host` | arm64 `-cpu` model (`host` with KVM, `max` for TCG) |
+| `ubuntu_version` | `24.04` | Base Ubuntu LTS (naming/tags) |
+
+The CI workflow builds both arches automatically: amd64 qcow2 on a standard runner,
+arm64 qcow2 on a native `ubuntu-24.04-arm` runner, and both AMIs from a single runner
+(the build instance runs in AWS).
+
+## First boot
+
+On the first boot of any instance launched from the image:
+
+1. `x-ui-firstboot.service` runs **before** `x-ui.service`.
+2. It generates a unique admin username/password, a random panel port, a random
+   base path, and an API token.
+3. Credentials are written to `/etc/x-ui/credentials.txt` (root-only) and shown
+   in `/etc/motd`. Retrieve them with `sudo cat /etc/x-ui/credentials.txt`.
+4. The panel then starts on the random port. `admin/admin` never exists.
+
+## CI
+
+`.github/workflows/image.yml` runs this build on `release: published` (and via
+`workflow_dispatch`), attaching the compressed `qcow2` to the release and
+building the AMI when AWS credentials are configured.
+
+## A note on host firewalls
+
+`scripts/harden.sh` intentionally does **not** enable a restrictive host
+firewall. 3x-ui opens Xray inbound ports on admin-chosen ports at runtime, which
+a host firewall would block. Use your cloud provider's security groups/firewall
+instead, and open the panel port + your inbound ports there. If you still want a
+host firewall, add `ufw` rules in `harden.sh` allowing SSH, the panel port and
+your inbound ports.

+# Capturing the Real Client IP
+
+When an Xray inbound sits behind an intermediary — a CDN like Cloudflare, an L4 tunnel/relay,
+or another panel — the IP that Xray sees is the **intermediary's** address, not the visitor's.
+That intermediary IP is what shows up in the panel's online/IP view and what the per-client
+**IP limit** counts against, which makes both useless behind a proxy.
+
+Xray-core can recover the real visitor IP. 3x-ui exposes the two mechanisms in the inbound form
+and feeds the recovered IP into the same pipeline that drives IP-limit enforcement, the online
+list, and multi-node sync — so once it is set, everything downstream just works.
+
+## Where to set it
+
+Open an inbound → **Transport / Stream Settings** → enable **Sockopt** → use the
+**Real client IP** preset selector:
+
+| Preset | What it does | Use for |
+|---|---|---|
+| **Off / direct** | Clears both fields. | Inbound reachable directly by clients. |
+| **Cloudflare CDN** | Sets `sockopt.trustedXForwardedFor = ["CF-Connecting-IP"]`. | WebSocket / HTTPUpgrade / XHTTP behind Cloudflare's CDN (orange cloud). |
+| **L4 relay / Spectrum (PROXY)** | Sets `acceptProxyProtocol = true`. | An L4 tunnel/relay in front, or Cloudflare **Spectrum**. |
+
+The raw `Proxy Protocol` switch and `Trusted X-Forwarded-For` list stay visible below the preset
+selector for manual / advanced tuning — the presets just fill them in for you.
+
+## Scenario 1 — Cloudflare CDN
+
+Cloudflare's CDN (the orange cloud) forwards the visitor's IP in the `CF-Connecting-IP` request
+header. Xray reads it when the transport is **WebSocket**, **HTTPUpgrade**, or **XHTTP** and
+the header name is listed in `sockopt.trustedXForwardedFor`.
+
+```json
+"streamSettings": {
+  "network": "ws",
+  "sockopt": { "trustedXForwardedFor": ["CF-Connecting-IP"] }
+}
+```
+
+Pick the **Cloudflare CDN** preset. You can add `X-Real-IP`, `True-Client-IP`, or `X-Client-IP`
+to the list if a different upstream uses those.
+
+> This is **not** the same as Cloudflare Spectrum. The free/CDN tier forwards HTTP headers — use
+> this scenario. Spectrum (a TCP/L4 product) can send the PROXY protocol — use Scenario 2.
+
+## Scenario 2 — L4 tunnel / relay or Cloudflare Spectrum (PROXY protocol)
+
+For a TCP-level front (HAProxy, gost, nginx `stream`, an Xray dokodemo-door relay, or Cloudflare
+Spectrum), the real IP is carried in the **PROXY protocol** header. Enable
+`acceptProxyProtocol` and make sure the **upstream emits PROXY protocol** — otherwise the
+connection will fail.
+
+```json
+"streamSettings": {
+  "network": "tcp",
+  "sockopt": { "acceptProxyProtocol": true }
+}
+```
+
+Pick the **L4 relay / Spectrum (PROXY)** preset. Works on TCP/RAW, WebSocket, HTTPUpgrade, gRPC
+and XHTTP; **not** on mKCP. The front must be configured to send the header, e.g.:
+
+- **HAProxy**: `server backend 127.0.0.1:443 send-proxy` (or `send-proxy-v2`).
+- **nginx** (`stream {}` block): `proxy_protocol on;` on the `server`, and on the upstream side
+  `proxy_protocol on;` in the `server` that connects to Xray.
+
+## Transport support matrix

+| Mechanism | TCP/RAW | mKCP | WebSocket | gRPC | HTTPUpgrade | XHTTP |
+|---|:--:|:--:|:--:|:--:|:--:|:--:|
+| `trustedXForwardedFor` (header) | – | – | ✅ | – | ✅ | ✅ |
+| `acceptProxyProtocol` (PROXY)   | ✅ | – | ✅ | ✅ | ✅ | ✅ |
+
+The form shows a warning when you select a preset that the current transport cannot honor.
+
+> **Use one, not both.** `acceptProxyProtocol` and `trustedXForwardedFor` are independent — the
+> first reads the real IP from the L4 PROXY header, the second from an HTTP request header. On
+> WebSocket / HTTPUpgrade / XHTTP, xray applies the HTTP header *last*, so a stale
+> `trustedXForwardedFor` would override (and defeat) a PROXY-protocol setup. The presets are
+> mutually exclusive and clear the other field for you; only mix them by hand if you know your
+> upstream chain needs it.
+
+## Multi-node
+
+No extra configuration is needed. The inbound's `streamSettings` (including these sockopt
+fields) is pushed to child nodes verbatim, so the node's Xray records the real IP, and the
+parent panel pulls each node's per-client IPs roughly every 10 seconds. The real visitor IP
+shows up on the parent automatically.
+
+## Security note
+
+Both `acceptProxyProtocol` and `trustedXForwardedFor` are **server-side only** — they are
+stripped from subscription output, so they never reach clients. Only enable
+`trustedXForwardedFor` when the inbound is genuinely behind a trusted proxy that sets the
+header; otherwise a client could spoof the header and forge its own source IP.
+
+## Verifying
+
+1. Set the preset and save the inbound.
+2. Inspect the generated Xray config and confirm `streamSettings.sockopt` carries the expected
+   field (`trustedXForwardedFor` or `acceptProxyProtocol`).
+3. Connect through the intermediary, then open the client's IPs / online view in the panel — it
+   should show the real visitor IP rather than the CDN/relay address.
