feat: Updated site

Converts Vantage from a single-admin self-hosted app into a multi-tenant
SaaS. Org isolation is org_id row-scoping in one shared deployment and
database; each org gets a subdomain via wildcard DNS, but the hostname is
a routing hint and never an authorization boundary.

- Orgs, users and roles (owner|admin|member) with local password auth,
  first-run bootstrap, and per-org OIDC replacing the global provider
- Redis sessions carrying org and role; host/session mismatch guard
- Every tenant-scoped collection carries org_id; handlers take org from
  the session only, never from client input
- Agent gRPC path resolves org from the servers record, so agent configs
  and the shared gRPC host are unchanged
- Per-org settings and ESO read token, replacing global singletons
- Frontend: login, setup and org settings pages; org-aware AuthProvider
- Migrations 0001-0003 backfill an existing single-tenant instance

Reviewed per task plus a whole-branch and a migration-focused pass.

+## Subsystems
+
+### SSH keys
+
+Upload a public key, assign it per server, revoke softly. The agent diffs desired vs on-disk state and rewrites `/root/.ssh/authorized_keys` atomically. Keys can also be generated _on_ a server by the agent; the private half can optionally be uploaded and is stored AES-256-GCM encrypted.
+
+### Workflows
+
+A library of reusable **steps** (bash or PowerShell scripts with declared inputs, outputs, and secret refs) composed into **workflows** targeting a set of servers. Running one snapshots the resolved steps into a `WorkflowRun`, then dispatches `RunStepCmd` over the agent command stream. Step stdout/stderr streams back as `StepOutputChunk` and is written to a log file on disk; the UI streams it live. Steps support `on_failure: stop|continue|retry`, per-run env passed between steps via `output_env`, and a per-run workspace directory the agent cleans up at the end.
+
+Default steps are seeded per org at boot (`SeedDefaultSteps`). Logs are swept by retention (`workflow_log_retention_days`; nil = 30 days, 0 = forever).
+
+### Monitors
+
+HTTP, TCP, ICMP and TLS checks. Each monitor has a `runner`: `"server"` (executed by the server-side scheduler) or a `server_id` (pushed to that agent, which runs it locally and reports results). Consecutive failures beyond `retries` flip state to `down`, open an `Incident`, and notify. Hourly `Rollup` documents back the uptime graphs.
+
+### Notification channels
+
+Per-org outbound destinations: `webhook`, `smtp`, `discord`, `slack`, `telegram`. Monitors reference channels by ID. Channels are testable from the UI.
+
+### Secrets vault
+
+Key/value pairs grouped by name, encrypted at rest with AES-256-GCM. Consumed two ways: referenced by workflow steps via `secret_refs` (injected as env at execution), and read by Kubernetes External Secrets Operator via `GET /api/secrets/:group/values` using a bearer token whose SHA-256 hash is stored in settings.
+
+### Browser console
+
+`POST /api/console/connect` mints a one-time session token; `GET /api/console/tunnel` upgrades to a WebSocket and proxies to **guacd** (Apache Guacamole daemon) using `github.com/wwt/guac`. SSH connections authenticate with a stored private key; RDP/VNC credentials are encrypted, single-use, and consumed when the tunnel opens.
+
+### Inventory and OS updates
+
+Agents report CPU/memory/swap/partitions/kernel — metrics every 30s, full static snapshot every 15 min. They also check for pending OS package updates hourly and can apply them on command (`ApplyUpdatesCmd`).
+
+### Agent self-update
+
+`UpdateAgentCmd` carries a target version and Gitea base URL; the agent downloads and replaces itself.
+
+### Marketing site and sitesvc
+
+`site/` is a separate Next.js app built exactly like `web/` — `output: "standalone"`, run by Node in a `node:26-alpine` image, listening on `3000` and published as `3001`. Both of its forms post to `sitesvc`; the control plane is not involved and has no public signup endpoint.
+
+`sitesvc/` (port `8082`) owns both flows end to end:
+
+| Form                | Endpoint                  | Effect                                                                  |
+| ------------------- | ------------------------- | ----------------------------------------------------------------------- |
+| Contact             | `POST /api/contact`       | Emails `support@hostxtra.co.uk`, `Reply-To` the sender. Nothing stored. |
+| Create organisation | `POST /api/signup`        | Records a pending signup and emails a verification link.                |
+| Verification link   | `GET /api/verify?token=…` | Creates the org and its owner, then redirects to the org's sign-in page (`APP_LOGIN_URL` with `{slug}` filled in). |
+
+All three are deliberately **excluded from the self-hosted deployment**: `deploy/docker-compose.yml` mentions none of them, and they live in `deploy/docker-compose.site.yml` instead.
+
+```bash
+# self-hosted install — no marketing site, no sitesvc
+docker compose up -d
+
+# vantage.hostxtra.co.uk — control plane plus the public site
+docker compose -f docker-compose.yml -f docker-compose.site.yml up -d
+```
+
+### Signup and verification
+
+**Nothing is written to `orgs` or `users` until the emailed link is opened.** A signup lands in sitesvc's own `site_pending_signups` collection holding the org name, the address, and the password already bcrypt-hashed at cost 12. The consequence is worth stating: an address nobody controls can never occupy an email, hold an organisation slug, or produce an account that can sign in. It also means the control plane's login path needs no concept of "unverified".
+
+- The token is 32 random bytes; only its **SHA-256 hash** is stored, so a leaked database yields no working links.
+- `Verify` deletes the pending record **atomically before provisioning** (`FindOneAndDelete`), so a double-clicked link cannot create two organisations — the second delete matches nothing.
+- Links expire after 24 hours, and a **TTL index** lets Mongo drop abandoned signups so password hashes do not linger.
+- Re-submitting the form for the same address replaces the previous pending record, so only the newest link works.
+- If the owner insert fails after the org is created, the org is rolled back rather than stranded holding a slug. The rollback refuses to touch an org that has users.
+- Rate limited to 3 signups per client IP per hour, plus a honeypot field.
+
+### The one piece of duplicated logic
+
+`sitesvc/internal/provision` and `sitesvc/internal/models` mirror the control plane's slug rules, reserved names, bcrypt cost and document shapes. They are duplicated rather than imported because sitesvc is a separate module that deliberately does not depend on the server.
+
+**Nothing enforces the match automatically.** If the control plane's `Slugify`, `reservedSlugs`, `CreateOrg` or `CreateUser` change, update `sitesvc/internal/provision` in the same commit — a divergence would provision tenants under rules the app does not agree with.
+
+sitesvc also (re)declares the unique indexes on `users.email` and `orgs.slug` at boot so it does not depend on the server having started first. Creating an existing index is a no-op.
+
+---
+
+## Auth and Orgs
+
+- **Bootstrap** — first run has no users. `GET /auth/bootstrap-status` drives `/setup`, `POST /auth/bootstrap` creates the first org plus its owner.
+- **Local auth** — email + password (bcrypt), `POST /auth/login`.
+- **OIDC** — configured _per org_ (`org_oidc`), issuer + client ID + encrypted client secret. `/auth/oidc/start` → `/auth/oidc/callback`.
+- **Sessions** — opaque 32-byte hex ID in the `km_session` cookie, session body stored in Redis with a 24h TTL.
+- **Roles** — `owner`, `admin`, `member`. `/api/settings` and `/api/org/*` require owner or admin.
+- **Host/org guard** — `APP_ROOT_LABEL` (default `vantage`) defines the app root label. A request to `<slug>.vantage.<tld>` resolves that org from the slug and rejects sessions belonging to a different one. Org lookups are cached for 60s.
+
+Unique indexes on user email and org slug are a **security property**, not an optimisation: `GetUserByEmail` does an unscoped `FindOne`, so duplicates would let the OIDC cross-org guard compare against an arbitrary user. Same for duplicate settings docs and duplicate ESO token hashes.

-No streaming — polling only. Poll interval: **30 seconds**.
+`CommandStream` is the only streaming RPC: the agent authenticates once with `AgentReady`, then the server pushes `ServerCommand`s and the agent replies with `CommandResult`, `StepResult`, or `StepOutputChunk`.
+
+`ServerCommand` variants: `GenerateKeyCmd`, `DeleteKeyCmd`, `UpdateAgentCmd`, `ApplyUpdatesCmd`, `RunStepCmd`, `CleanupWorkspaceCmd`.
+
+Key-state polling stays on the 30s `SyncKeys` interval. Full message definitions live in `proto/vantage/v1/vantage.proto`.

+`site_pending_signups` is written only by sitesvc and holds unverified signups; the control plane neither reads nor knows about it.

+- `servers.agent_token_hash` stores SHA-256 of the token, never plaintext. `pre_reg_token` is cleared after `Register()`. `status` is `pending` → `active` on register, `offline` when `last_seen` passes the threshold (swept every 2 min).
+- `servers.inventory` holds the latest metrics snapshot with separate `metrics_at` / `static_at` timestamps.
+- `keys.private_key_enc` and `passphrase_enc` are AES-256-GCM; the JSON form exposes only `has_private_key` / `has_passphrase`.
+- `assignments.revoked_at: null` means active. Revocation is soft, preserving audit history.
+- `workflow_runs.steps_snapshot` freezes the resolved steps so editing the library never rewrites history.

 ```
 1. Load config

 ## Server Registration Flow
 
-1. Click **Add Server** in the UI
-2. Backend generates a short-lived pre-registration token (TTL: 1 hour) and a `server_id`
-3. UI displays a one-liner install command with copy button:
+1. **Add Server** in the UI calls `POST /api/servers/new`, which generates a `server_id` and a pre-registration token (TTL 1 hour, single-use).
+2. The UI shows a one-liner:
     ```bash
     curl -fsSL https://vantage.yourdomain.com/install | \
       bash -s -- --server-id=<id> --token=<token>
     ```
-4. Install script:
-    - Detects arch (`amd64` / `arm64`)
-    - Downloads agent binary from Gitea release
-    - Verifies SHA-256 checksum
-    - Writes `/etc/vantage/config.yaml`
-    - Installs and starts systemd unit
-5. On first `SyncKeys` call, server marks status as `active`
+    Windows gets the `/install.ps1` equivalent.
+3. The script detects arch, downloads the agent from the Gitea release, verifies the SHA-256 checksum, writes the config, installs and starts the service.
+4. The server flips to `active` on first sync.
 
-The backend serves `/install` dynamically, injecting the latest agent version by querying the Gitea API for the most recent `agent/v*` release tag.

-- Agent authenticates with a per-server token stored at `/etc/vantage/config.yaml` (`0600`)
-- Server stores `SHA-256(agent_token)` — never the plaintext token
-- Private keys generated by agents are encrypted at rest in MongoDB (AES-256)
-- `authorized_keys` written as `0600`, owned by root
-- Pre-registration tokens are short-lived (1 hour) and single-use
-- Agent runs as `root` (required for `/root/.ssh/authorized_keys` writes)
+- gRPC over TLS; agents connect outbound only, no inbound firewall holes on managed servers.
+- Per-server agent token stored as SHA-256 on the server, plaintext only in the agent's `0600` config.
+- Pre-registration tokens are short-lived (1 hour) and single-use.
+- AES-256-GCM at rest for private keys, key passphrases, vault secrets, OIDC client secrets, RDP/VNC credentials.
+- Console session tokens are one-time; RDP credentials are consumed on tunnel open.
+- ESO read token stored as a SHA-256 hash and rotatable.
+- Unique indexes on user email, org slug, settings org, and ESO token hash are load-bearing for tenant isolation.
+- `authorized_keys` written `0600`, owned by root. The agent runs as root because it must.
+- Every mutating API path writes an audit event.

 ## Design Decisions
 
-- **gRPC over REST for agent communication** — strong typing, easy versioning, bi-directional streaming available later if push-based updates are needed
-- **Poll-only, no streaming** — 30s interval is sufficient for a homelab; simplifies agent implementation
-- **Outbound-only agent connections** — no inbound firewall holes required on managed servers
-- **Atomic `authorized_keys` rewrite** — write to `.tmp` then `os.Rename()` prevents partial writes
-- **Fingerprint diffing before write** — avoids unnecessary disk writes on unchanged state
-- **Soft revocation** — `revoked_at` timestamp rather than hard deletes; preserves audit history
-- **root only** — manages `/root/.ssh/authorized_keys` only; no per-user key management
-- **Gitea releases for agent binaries** — slots into existing act_runner CI pipeline; install script queries Gitea API for latest version at serve time
+- **gRPC for agent traffic** — strong typing and cheap versioning; polling for state, one bidirectional stream for commands.
+- **Outbound-only agents** — no inbound ports on managed servers, works behind NAT.
+- **Poll for keys, push for commands** — a 30s key poll is fine, but running a workflow step should not wait up to 30s.
+- **Atomic `authorized_keys` rewrite** — temp file plus `os.Rename()`; a machine that dies mid-write keeps the old file.
+- **Fingerprint diffing before write** — no disk churn on unchanged state.
+- **Soft revocation** — `revoked_at` rather than deletes; preserves audit history.
+- **Run snapshots** — workflow runs freeze their resolved steps so editing a step never rewrites past runs.
+- **Monitors run in two places** — server-side for external endpoints, agent-side for anything only reachable from inside the target network.
+- **Redis for sessions only** — all durable state stays in MongoDB; losing Redis logs everyone out and nothing else.
+- **guacd for console** — protocol handling is Guacamole's problem, not ours; we proxy the WebSocket and manage credentials.
+- **`org_id` on every document** — isolation enforced at the query layer, not by separate databases.
+- **root only** — manages `/root/.ssh/authorized_keys`; no per-user key management.
+- **Windows agents are second-class by design** — register, heartbeat, run steps, report inventory; no `authorized_keys` management.

-# Vantage Web Console (Guacamole Replacement) — Design
-
-**Date:** 2026-07-17
-**Status:** Approved design, pre-implementation
-
-## Goal
-
-Add a browser-based remote-access console to Vantage — SSH, RDP, and VNC into
-managed servers — as a self-hosted Guacamole replacement. Users select an SSH
-key to connect over SSH. RDP targets are reachable from a new Windows agent that
-registers the host and reports status. Windows agent ships as an MSI installer
-produced by CI.
-
-## Non-Goals (YAGNI)
-
-- Session recording / replay (may be added later).
-- Native Go RDP implementation (guacd handles protocol translation).
-- Per-user Linux/Windows account management from the agent.
-- Tunneling console traffic through the agent (direct network path assumed).
-
----
-
-## Architecture
-
-```
-Browser (guacamole-common-js, vendored — no CDN)
-   │  Guacamole protocol over WebSocket
-   ▼
-Go server: /api/console/tunnel   (github.com/wwt/guac)
-   │  Guacamole protocol over TCP :4822
-   ▼
-guacd container (Apache Guacamole daemon)
-   │  SSH :22 / RDP :3389 / VNC :5900  — direct to target IP
-   ▼
-Target host (LAN / VPN line-of-sight from server)
-```
-
-- **Browser:** loads vendored `guacamole-common-js`, renders RDP/VNC display and
-  SSH terminal. No external CDN (matches existing infra rules).
-- **Go server:** exposes a WebSocket tunnel endpoint using `github.com/wwt/guac`
-  (Go Guacamole tunnel library). No Java `guacamole-client` required.
-- **guacd:** new container in `deploy/docker-compose.yml`, bound to the internal
-  docker network only, reachable by the server on `:4822`.
-- **Network path:** guacd connects **directly** to the target IP. Requires the
-  central server to have network line-of-sight to hosts (homelab LAN / VPN). The
-  agent's outbound-only guarantee is unchanged — the console path is
-  server→target, not agent-mediated.
-
----
-
-## Data Model Changes
-
-### `keys` — extend to hold private material
-
-```json
-{
-  "key_id": "uuid",
-  "label": "dom-macbook",
-  "public_key": "ssh-ed25519 AAAA...",
-  "private_key_enc": "<AES-256-GCM ciphertext | null>",
-  "has_private": true,
-  "passphrase_enc": "<AES-256-GCM ciphertext | null>",
-  "fingerprint": "SHA256:...",
-  "source": "uploaded|generated",
-  "created_at": "ISODate"
-}
-```
-
-- A key may be created from an uploaded **private+public** pair, upload of a
-  public key only, or agent generation.
-- Agent key generation now also uploads `private_key_enc` (reuses the existing
-  AES-256 key used for at-rest encryption). Private key no longer stays local
-  only — it is stored encrypted so the console can reuse it.
-- Optional `passphrase_enc` for passphrase-protected private keys.
-- Console lists only keys where `has_private = true`.
-
-### `servers` — extend with console metadata
-
-```json
-{
-  "...": "...existing fields...",
-  "os_type": "linux|windows",
-  "console_protocols": ["ssh"],
-  "ssh_port": 22,
-  "rdp_port": 3389
-}
-```
-
-- `os_type` set at registration from the agent.
-- `console_protocols` lists enabled protocols per server (`ssh`, `rdp`, `vnc`).
-- Port fields default to standard ports, overridable in the UI.
-
-### `console_sessions` — new collection (audit)
-
-```json
-{
-  "session_id": "uuid",
-  "server_id": "uuid",
-  "protocol": "ssh|rdp|vnc",
-  "key_id": "uuid | null",
-  "user": "who opened it",
-  "started_at": "ISODate",
-  "ended_at": "ISODate | null",
-  "client_ip": "string"
-}
-```
-
----
-
-## Session Broker + Connection Flow
-
-New service: `server/internal/services/console.go`.
-
-1. Browser `POST /api/console/connect`
-   `{ server_id, protocol, key_id?, rdp_username?, rdp_password? }`.
-2. Broker validates request, loads the server (host IP, port for protocol),
-   loads the key and **decrypts `private_key_enc` in memory only**.
-3. Builds the guacd connection parameter map:
-   - **SSH:** `hostname`, `port`, `username`, `private-key` (decrypted),
-     `passphrase` (if any).
-   - **RDP:** `hostname`, `port`, `username`, `password`, `security=any`,
-     `ignore-cert=true`.
-   - **VNC:** `hostname`, `port`, `password`.
-4. Creates a `console_sessions` document, returns a short-lived signed session
-   token.
-5. Browser opens WebSocket `/api/console/tunnel?token=…`. The `wwt/guac` handler
-   validates the token, dials guacd `:4822`, and pipes bytes in both directions.
-6. On socket close, the broker sets `ended_at` on the session doc.
-
-### Security
-
-- Decrypted private keys and RDP passwords are **never persisted, never logged,
-  never sent to the browser** — passed only to guacd.
-- Session token: short TTL (~60s to open the WebSocket), single-use,
-  HMAC-signed, bound to the authenticated user.
-- guacd is bound to the internal docker network only; not exposed publicly.
-- At-rest encryption (`private_key_enc`, `passphrase_enc`) reuses the existing
-  AES-256 key already used for agent-generated private keys.
-

-
-## Windows Agent
-
-Same Go codebase as the Linux agent, with a reduced role: **register +
-heartbeat + status only**. No `authorized_keys` management (meaningless on
-Windows).
-
-- Build target: `GOOS=windows GOARCH=amd64` → `vantage-agent-windows-amd64.exe`.
-- Agent detects OS at registration and sends `os_type=windows`.
-- The key-sync loop is disabled on Windows via a runtime OS check (or build tag)
-  — no `authorized_keys` writes are ever attempted.
-- Config file: `C:\ProgramData\vantage\config.yaml`, locked down via ACL to the
-  equivalent of `0600`.
-- Runs as a Windows service via **nssm**.
-
----
-
-## Windows Installer (MSI)
-
-Agent ships as a WiX v4 MSI produced in CI.
-
-- **WiX v4** chosen because it is a dotnet tool that builds MSIs
-  **cross-platform** — runs on the Linux Gitea act_runner. (Inno Setup is
-  Windows-only and does not fit the runner.)
-- MSI bundles `vantage-agent.exe`, installs it to `C:\Program Files\Vantage\`,
-  and registers the nssm service (ships nssm or uses a CustomAction).
-- Accepts install parameters as MSI properties for silent/headless install:
-  ```
-  msiexec /i vantage-agent.msi /qn SERVERID=<id> TOKEN=<token> SERVERURL=vantage..:9090
-  ```
-- GUI install (double-click) prompts for server-id / token / server-url via a
-  dialog.
-
-### Two install paths
-
-1. **Installer direct** — user downloads `vantage-agent.msi`, double-clicks,
-   fills the dialog. No script required.
-2. **PowerShell one-liner** — served dynamically (like the existing bash
-   `/install`). Script downloads the `.msi`, verifies SHA-256, then runs
-   `msiexec /qn` with injected `SERVERID` / `TOKEN` / `SERVERURL`. Used by the
-   copy-paste "Add Server" flow.
-
-The PowerShell script (`/install.ps1`) steps:
-1. Detect arch.
-2. Download `vantage-agent.msi` from the latest Gitea `agent/v*` release.
-3. Verify SHA-256 against `checksums.txt`.
-4. Run `msiexec /i vantage-agent.msi /qn SERVERID=.. TOKEN=.. SERVERURL=..`.

-## Frontend Routes
-
-| Route                     | Change                                                        |
-| ------------------------- | ------------------------------------------------------------- |
-| `/servers`                | Show `os_type` badge, enabled console protocols               |
-| `/servers/[id]`           | Add **Connect** button(s) per enabled protocol                |
-| `/servers/[id]/console`   | New — full-screen console (guacamole-common-js), key picker   |
-| `/servers/new`            | Offer Windows (MSI) vs Linux (bash) install instructions      |
-
-Console page: select protocol + SSH key (SSH) or enter RDP credentials, call
-`/api/console/connect`, open the tunnel WebSocket, mount the Guacamole client.
-
----
-
-## CI/CD Changes
-
-### `agent-release.yml`
-
-- Add `windows/amd64` build: `vantage-agent-windows-amd64.exe`.
-- Add WiX v4 MSI build job → `vantage-agent.msi`.
-- Add both to `checksums.txt` and release assets.
-
-Release assets become:
-- `vantage-agent-linux-amd64`
-- `vantage-agent-linux-arm64`
-- `vantage-agent-windows-amd64.exe`
-- `vantage-agent.msi`
-- `checksums.txt`
-
-### `server-deploy.yml`
-
-- Add guacd service to `deploy/docker-compose.yml` (deployed alongside server).
-
----
-
-## New Dependencies
-
-- **Go:** `github.com/wwt/guac` (Guacamole tunnel/WebSocket in Go).
-- **Container:** `guacamole/guacd` official image.
-- **Frontend:** vendored `guacamole-common-js` (no CDN).
-- **CI:** WiX v4 dotnet tool; nssm binary bundled for the MSI.
-
----
-
-## Open Implementation Notes
-
-- Confirm `wwt/guac` API surface for connection-parameter passing and token auth
-  binding during implementation.
-- nssm packaging inside MSI: bundle the nssm binary as a payload + CustomAction,
-  or run `sc.exe`-based service install if nssm proves awkward in WiX.
-- ACL hardening of `C:\ProgramData\vantage\config.yaml` in the MSI CustomAction.

+            <p>
+              Vantage started as a weekend fix for a bad afternoon. A laptop was lost, and finding every server that
+              trusted its key meant SSHing into each one with a text editor open. The list lived in someone&apos;s head.
+              Two of the boxes were not on it.
+            </p>
+            <p>
+              The obvious tools were all heavier than the problem. A configuration management stack to write one file. A
+              bastion host that becomes the thing you now have to keep alive. A certificate authority with a rotation
+              story nobody wanted to own.
+            </p>
+            <p>
+              So it began with one job done properly: hold <code>authorized_keys</code> to a known state. Then the same
+              agent turned out to be the right place to run a deploy script, check whether a service was answering, and
+              open a shell when something was on fire. Each addition had to earn its place by riding the connection that
+              already existed.
+            </p>
+            <p>
+              Today it runs across homelabs, small hosting providers, and agencies who inherit client servers and need
+              to prove who can reach them.
