feat: Docker and helm charts

Session.Close now closing its own accepted conn (from the prior fix wave)
made net.ErrClosed on the guacd-side reader indistinguishable from a real
remote failure, so a normal browser-tab close could race the handler's
defer and intermittently log console.proxy_failed on a healthy session.
Add a closing flag, set before Close's sync.Once body actually tears
anything down, that setReason respects -- a deliberate local teardown can
no longer produce or race in a failure reason, while Close's own explicit
reason argument still wins normally.

 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`) from `VANTAGE_DEFAULT_STEPS_DIR`, which `server/Dockerfile` bakes to `/opt/default-steps` from the repo's `default_steps/`. Deliberately **not** under `/data` — that is a bind mount, so the library would be editable from the host. Adding a step there means committing a file and rebuilding, which is why `default_steps/` is in the `server` rebuild trigger. **Steps with `source: "default"` are read-only**: `UpdateStep`/`DeleteStep` refuse with `ErrDefaultStep` (409), because seeding rewrites them on every boot, so an edit would silently revert and a delete would come back. `web/` mirrors this — the step modal opens read-only, Delete is hidden, and the designer's per-step script override is `readOnly` for a default library step — but as elsewhere, the API is the boundary and the UI is the courtesy. Seeding writes straight to the collection rather than through `UpdateStep`, so the guard does not lock out the seeder. Logs are swept by retention (`workflow_log_retention_days`; nil = 30 days, 0 = forever).

 `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 `3003`. The contact form posts to `sitesvc`; account signup posts to `admin` (`NEXT_PUBLIC_ADMIN_API_URL`), which creates an HQ account, not an org — the control plane is not touched until the customer later creates a cloud instance from the portal.

 **`ADMIN_ORIGIN` must list every browser origin that calls admin — currently two**: `https://vantage-hq.hostxtra.co.uk` for the console, and `https://vantage.hostxtra.co.uk` because the marketing site's `/start` form posts account signups to admin directly. It is comma-separated. A missing origin does not produce a 403: `cors()` simply omits the `Access-Control-Allow-Origin` header and still answers the preflight `204`, so the browser blocks the request and **admin logs nothing at all**. Symptom is a CORS preflight failure on an endpoint that works fine under curl.
 
 `sitesvc/` (port `8082`) now owns only the contact flow:

MongoDB is external. `deploy/docker-compose.site.yml` adds five more — `site` (3003), `sitesvc` (8082), `admin` (8083), `adminsite` (3004) and `docsite` (3005) — and is only used on vantage.hostxtra.co.uk.
+
+`docsite` is the odd one: a **static** build served by `nginx:alpine-slim`, not a Node runtime, and it listens on `80` rather than `3000`. It is reached at **`vantage.hostxtra.co.uk/docs`** — a path on the marketing host, routed by its own Nginx Proxy Manager location, which must sort **above** the catch-all forwarding to `site:3003` or Next answers the 404. A path and not a subdomain because `*.vantage.hostxtra.co.uk` is the per-tenant instance namespace and `APP_ROOT_LABEL` would read a `docs.` label as a tenant slug. NPM forwards the **full** path upstream — it does not strip `/docs` — so `DOCS_BASE_URL`, the proxy location and the directory the image copies the build into (`/usr/share/nginx/html/docs`) must all agree. When they do not, the HTML loads and every asset 404s.
 
 `LICENSE_SIGNING_KEY` appears in **exactly one service in exactly one compose file**: `admin` in `docker-compose.site.yml`. It must never be added to `server`, and the self-hosted `docker-compose.yml` must never mention `admin` or `adminsite` at all. Admin uses an external Redis via `REDIS_ADDR`/`REDIS_USERNAME`/`REDIS_PASSWORD`; the base compose hardcodes `redis:6379` for `server`, so those variables reach admin only.

+`docsite/` is the one place the tokens are not consumed through Tailwind: everything below its token block maps Docusaurus's `--ifm-*` variables onto them. Docusaurus already stamps `data-theme` on `<html>`, which is the selector `site/`'s dark block keys on, so the built-in toggle needed no wiring. The rule holds all the same — no rule in that file outside the token blocks carries a hex. The one concession is `docsite/static/img/favicon.svg`, which must, for the same reason the email layout must: a browser tab cannot read a token.

 Tailwind in all three maps `var(--…)` references only, so **no component in any of them may carry a hex value**. The names differ per app on purpose, because each app has its own subject: `site/` calls the semantic three `--up`/`--pend`/`--down` for monitor state, `adminsite/` aliases them to `valid`/`warn`/`expired` for licence state, and `web/` to `success`/`warning`/`danger`. Same colours, honest names on each side.

 **Each image only rebuilds when its own inputs changed.** A `git diff` against `github.event.before` decides, which is why the checkout uses `fetch-depth: 0` — the default shallow clone has one commit and nothing to diff — and why `git` is installed in the `docker:dind` container. The mapping follows the build contexts exactly:

 `shared/` fans out to all three Go images because each of their Dockerfiles copies `shared/` from a root context — **if a fourth service ever imports `shared/`, add it to that list or it will ship stale**. A change to the workflow file rebuilds everything, since a build arg is baked into the image. So does anything that leaves no trustworthy base commit: a manual `workflow_dispatch`, a new branch, or a force-push whose old head is gone.
 
-The gap this leaves: **changing a repo variable pushes no commit, so nothing rebuilds.** After editing `API_URL`, `ADMIN_API_URL`, `HQ_URL` or `ADMIN_ENV`, run the workflow manually — that is what `workflow_dispatch` is there for. Base images also stop being refreshed on a service nobody touches; a periodic manual run covers that.

+| `API_URL`               | **not** a CI variable | `web` reads it at **runtime**, from the container environment — `next.config.ts` is evaluated when `server.js` boots in standalone mode, and the rewrites it feeds are server-side, never browser-side. Default `http://localhost:8080`; compose sets `http://server:8080`. `NEXT_PUBLIC_API_URL` is still honoured as a fallback for existing deployments. |
+| `SITE_API_URL`          | Variable | **browser-reachable** sitesvc URL, baked into the `site` image. Required — if empty, both forms report "not connected" and submit nowhere. Must also be in sitesvc's `SITE_ORIGIN`.                                                                        |

+| `SITE_URL`              | Variable | browser URL of the marketing site, baked into `adminsite` so `/login` can point at `/start`. **Signup has no page in `adminsite` at all** — one signup form, on `site/`. Empty renders no link rather than one that 404s.                                  |
+| `ADMIN_API_URL`         | Variable | **browser-reachable** admin URL, baked into **both** the `adminsite` and `site` images — `site/start` posts account signups straight to admin. Same footgun as `SITE_API_URL`: wrong here and every request fails at runtime with the not-connected panel. |
+| `ADMIN_ENV`             | Variable | `production` or `sandbox`; drives the persistent environment badge. Anything but `sandbox` reads as production.                                                                                                                                            |
+| `HQ_URL`                | Variable | optional; browser URL of the HQ portal, baked into `web` so an `hq`-sourced member links to where they are managed. Empty on self-hosted, which renders a plain label instead.                                                                             |
+| `PADDLE_CLIENT_TOKEN`   | Variable | **browser** Paddle token, baked into the `adminsite` image for checkout. A repo-variable change pushes no commit, so rebuild `adminsite` manually via `workflow_dispatch` after editing it.                                                                |
+| `PADDLE_ENV`            | Variable | `sandbox` or `production`; baked into `adminsite` AND read by `admin` at runtime. Selects which `catalogue` price IDs are served, and must match on both sides.                                                                                            |

+| `PADDLE_WEBHOOK_SECRET` | Secret   | webhook signature verification, read by `admin`. Boot-required — an unverified endpoint is one anyone can issue licences through.                                                                                                                          |
+| `DOCS_URL`              | Variable | site `url` baked into `docsite`; `https://vantage.hostxtra.co.uk`. Empty falls back to that default rather than breaking the build.                                                                                                                        |
+| `DOCS_BASE_URL`         | Variable | `/docs/`. Must match the NPM location and the directory the image serves from — all three, or the HTML loads and every asset 404s.                                                                                                                         |
+| `APP_URL`               | Variable | control-plane link in `docsite`'s navbar.                                                                                                                                                                                                                  |

 - **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.
 - **Deletion lives in the control plane** — admin sends the warnings because it knows the billing address; the control plane performs the delete because it is the only service that knows which collections carry `instance_id`. Mirroring that list into admin would drift, and a drift there deletes the wrong rows.

+## graphify
+
+This project has a knowledge graph at graphify-out/ with god nodes, community structure, and cross-file relationships.
+
+Rules:
+- For codebase questions, first run `graphify query "<question>"` when graphify-out/graph.json exists. Use `graphify path "<A>" "<B>"` for relationships and `graphify explain "<concept>"` for focused concepts. These return a scoped subgraph, usually much smaller than GRAPH_REPORT.md or raw grep output.
+- If graphify-out/wiki/index.md exists, use it for broad navigation instead of raw source browsing.
+- Read graphify-out/GRAPH_REPORT.md only for broad architecture review or when query/path/explain do not surface enough context.
+- After modifying code, run `graphify update .` to keep the graph current (AST-only, no API cost).

+  - {{ .Release.Name }}-mongo   (ClusterIP {{ .Values.mongo.port }})
+  - {{ .Release.Name }}-guacd   ({{ .Values.guacd.service.type }} {{ .Values.guacd.service.port }})

+
+By default the server/web/guacd services are ClusterIP only (no host port publishing,
+unlike the original docker-compose file). To expose them externally, set
+server.service.type / web.service.type / guacd.service.type to NodePort or LoadBalancer,
+or add an Ingress on top of the -web and -server services.
+
+Quick access via port-forward, e.g.:
+  kubectl port-forward svc/{{ .Release.Name }}-web {{ .Values.web.service.port }}:{{ .Values.web.service.port }}
+  kubectl port-forward svc/{{ .Release.Name }}-server {{ .Values.server.service.httpPort }}:{{ .Values.server.service.httpPort }}

+# Documentation site — design
+
+**Date:** 2026-07-28
+**Status:** approved
+
+## Problem
+
+Vantage has no user-facing documentation. Everything an operator needs — how to
+install self-hosted, how to enrol an agent, what a workflow step is, how a
+licence gets issued — lives either in `CLAUDE.md` (written for contributors, not
+users) or in the code. The marketing site sells the product and the control
+plane runs it; neither explains it.
+
+## Solution
+
+A fourth Next-adjacent frontend, `docsite/`, built with Docusaurus v3 and shipped
+alongside the marketing site.
+
+### Placement and deployment
+
+- Lives at repo root as `docsite/`.
+- Served at **`vantage.hostxtra.co.uk/docs`** — a path on the marketing site's
+  host, routed by a separate Nginx Proxy Manager custom location rather than by
+  `site/`. It is a path, not a subdomain, deliberately: `*.vantage.hostxtra.co.uk`
+  is the per-tenant instance namespace and `APP_ROOT_LABEL` resolves an org from
+  the label before `vantage`, so a `docs.` label there would be read as a tenant
+  slug.
+
+  This makes `baseUrl: "/docs/"` load-bearing. An NPM custom location forwards
+  the **full** request path upstream — it does not strip the `/docs` prefix — so
+  the container serves the build from `/usr/share/nginx/html/docs`, not from the
+  document root. Prefix, asset URLs and upstream paths then agree with no
+  rewrite rule to keep in step. Getting this wrong is quiet: the HTML loads and
+  every stylesheet and script 404s.
+- Added to **`deploy/docker-compose.site.yml` only**, published as `3005`.
+  `deploy/docker-compose.yml` (the self-hosted install) must never mention it,
+  exactly as it never mentions `site`, `sitesvc`, `admin` or `adminsite`.
+- Added to `.gitea/workflows/server-deploy.yml` as a seventh image, rebuilding
+  on `^docsite/` only, build context `docsite/`.
+
+### Runtime
+
+Docusaurus emits a fully static site, so unlike `site/`, `web/` and
+`adminsite/` there is no Node server at runtime. Two stages:
+
+1. `node:26-alpine` builder — `npm ci && npm run build` → `/app/build`.
+2. `nginx:alpine-slim` runner — copies `build/` to
+   `/usr/share/nginx/html/docs` (see the `/docs` prefix note above), plus a
+   small `nginx.conf` giving `try_files` a 404 fallback to Docusaurus's
+   `404.html` and long cache headers on `/docs/assets/`. A bare `/` request
+   redirects to `/docs/`, so hitting the container directly is not a blank 403.
+
+`nginx:alpine-slim` is roughly 12MB against `caddy:alpine`'s ~50MB, and nothing
+here needs Caddy's automatic TLS — the host proxy already terminates it.
+
+Build args, baked at build time the same way `site/`'s are:
+
+| Arg | Purpose |
+| --- | --- |
+| `DOCS_URL` | site `url`; defaults to `https://vantage.hostxtra.co.uk` |
+| `DOCS_BASE_URL` | site `baseUrl`; defaults to `/docs/`. Must match the NPM location and the runner's copy target |
+| `APP_URL` | navbar link to the control plane |
+| `HQ_URL` | navbar link to the HQ portal |
+
+### Theme
+
+`docsite/src/css/custom.css` carries `site/app/globals.css`'s token blocks
+**copied verbatim** — same names, same values — and maps Docusaurus's `--ifm-*`
+variables onto them. Docusaurus stamps `data-theme="light|dark"` on `<html>`,
+which is the same selector `site/`'s dark block already keys on, so the built-in
+toggle works with no extra wiring. Light is the default, matching `site/` and
+`adminsite/`.
+
+This makes a **fifth** copy of the token block (`site/`, `adminsite/`, `web/`
+dark-only, `shared/mail/templates/layout.html.tmpl` as literal hex, and now
+`docsite/`). Nothing enforces the match; `CLAUDE.md`'s Frontend section is
+updated to say so. No component in `docsite/` may carry a hex value.

+
+### Getting Started
+
+| Page | Covers |
+| --- | --- |
+| `what-is-vantage` | The control plane, the agent, what problem each solves |
+| `cloud-vs-self-hosted` | The two deployments, what differs (licensing, HQ-managed users, reaping) |
+| `self-hosted-install` | Prereqs (Docker, external MongoDB, DNS, TLS), `docker-compose.yml`, required env, `docker compose up -d` |
+| `first-login` | `/setup` bootstrap, first org and owner |
+| `first-server` | `POST /servers/new`, the install one-liner, Linux and Windows, watching it flip to `active` |
+| `claim-free-licence` | Linking the install to an HQ account, `claim-free` |
+
+`self-hosted-install` is the page the section exists for; it names every
+required environment variable with its consequence-of-omission, in particular
+`GRPC_HOST` (boot fails, no default is safe) and `KEY_ENCRYPTION_KEY`.
+
+### Vantage (the application)
+
+`servers` (agent install Linux/Windows, inventory, OS updates, agent
+self-update) · `ssh-keys` (upload, generate-on-server, assign, revoke, what the
+agent writes and when) · `workflows` (step library, default steps and why they
+are read-only, the designer, running, live logs, `on_failure`, `output_env`,
+workspaces, log retention) · `monitors` (the four check types, server vs agent
+runner, retries, incidents, uptime rollups) · `notification-channels` (five
+types, testing) · `secrets` (vault, `secret_refs` in steps, the ESO read path
+and its bearer token) · `browser-console` (SSH/RDP/VNC, one-time tokens) ·
+`audit-log` · `settings` (members and roles, OIDC per org, retention, ESO token,
+licence).
+
+### Vantage HQ (the portal)
+
+`accounts-and-signup` (account-first signup, email verification, an account is
+a team) · `people-and-roles` (owner/admin/member, invitations, accepting) ·
+`cloud-instances` (create, overview, granting members and what a grant actually
+is) · `self-hosted-instances` (purchase creates a placeholder, claim-link binds
+the real UUID, relink) · `licensing-and-entitlements` (tiers, metered server
+count, feature toggles, desired vs granted) · `billing` (Paddle as merchant of
+record, checkout, the customer portal, changing configuration) · `free-tier`
+(limits, the renewal window, reaping on cloud).
+
+### Reference
+
+`environment-variables` (server, sitesvc, admin, agent) · `rest-api` (the route
+tables, grouped as in `CLAUDE.md`) · `grpc-api` (the eight RPCs, the command
+stream) · `agent-config` (config.yaml, paths, permissions) ·
+`ports-and-networking` (which ports, which direction, what needs to be
+reachable) · `troubleshooting`.
+
+### Operations
+
+`upgrading` (pull and recreate) · `backups` (MongoDB is the durable state; Redis
+is sessions only) · `agent-updates` · `ci-cd` (which image rebuilds when, and
+the repo-variable gap that pushes no commit).
+
+## Writing rules
+
+- Every guide is task-shaped: numbered steps, real paths and commands taken from
+  the repository, never invented UI.
+- Behaviour that is a hard refusal gets an admonition, not a paragraph: default
+  steps are read-only (409 `ErrDefaultStep`), `POST /license` answers 409
+  `cloud_managed` on cloud, HQ-sourced users cannot have their role changed
+  locally (409 `ErrHQManaged`).
+- Where the UI enforces something, say that the API is the boundary and the UI
+  is the courtesy — the same phrasing the codebase uses.
+- No screenshots in this pass. They rot faster than prose and there is no
+  capture pipeline.
+
+## Out of scope
+
+- Versioned documentation. One version, tracking `main`. Docusaurus versioning
+  can be switched on later without restructuring.
+- Internationalisation.
+- Screenshots and diagrams beyond what Mermaid renders inline.
+- A docs search backed by an external service.

+# Agent-relayed console proxy
+
+Date: 2026-07-29
+Status: approved, not yet implemented
+
+## Problem
+
+`consoleTunnel` builds guacamole parameters from `srv.IPAddress` and hands them
+to guacd, which then dials the target itself. On a self-hosted deployment the
+control plane and the managed servers share a network, so that works. On Vantage
+Cloud they do not: guacd runs on the cloud host and the customer's server is on
+an RFC1918 address behind their NAT. Every cloud console session to a private
+address fails, for SSH, RDP and VNC alike.
+
+Agents already hold an outbound gRPC connection to the control plane. The fix is
+to carry the console's TCP bytes over that existing path rather than asking guacd
+to route somewhere it cannot reach.
+
+## Decisions
+
+**Self-relay only.** The agent relays to its own host and nowhere else. It is
+never told a hostname; the host is hardcoded to `127.0.0.1` on the agent side and
+only the port comes from the server. A jump-host mode (reaching agentless devices
+through a neighbouring agent) was rejected: it would give an agent the power to
+dial arbitrary addresses on the customer's LAN, and the console today can only
+target servers that run an agent anyway.
+
+**A dedicated bidirectional RPC, one stream per TCP connection.** Multiplexing
+console bytes onto the existing `CommandStream` was rejected — that stream
+already carries control commands and workflow stdout, and an RDP framebuffer
+would introduce head-of-line blocking against key sync and step output. A
+separate stream also gets connection lifetime, flow control and close semantics
+for free instead of needing a hand-rolled connection-ID demux.
+
+**Always proxy, both deployments.** Direct dial is deleted rather than kept as a
+self-hosted fast path or a fallback. One code path means one tested code path,
+and the cloud path is the one no developer can reproduce locally. A
+try-direct-then-fall-back design was rejected outright: it puts a timeout in
+front of every private-network session and makes "which path did this session
+use" unanswerable from the audit log.
+
+The cost is that the console now requires a live agent, where a self-hosted
+deployment could previously reach a server whose agent was down. In practice an
+offline agent almost always means an offline host, and the failure is now an
+immediate, explicit refusal instead of a hang.
+
+## Architecture
+
+Three parties rendezvous on a single `proxy_id`. Neither guacd nor the agent
+changes which direction it dials: guacd still makes an outbound TCP connection,
+the agent still only connects outbound to the control plane.
+
+```
+consoleTunnel (server)
+  1. proxy.Open(instance, server_id, port) -> proxy_id + ephemeral listener :N
+  2. push OpenProxyCmd{proxy_id, port} down the existing CommandStream
+  3. agent dials 127.0.0.1:port locally, then opens ProxyStream and sends
+     ProxyOpen{server_id, agent_token, proxy_id}
+  4. guacd dials PROXY_ADVERTISE_HOST:N  (the params it was handed in step 1)
+  5. registry holds both halves -> io.Copy in both directions
+  6. either side EOFs -> close listener, close stream, drop the registry entry
+```
+
+Steps 3 and 4 race, so a registry entry has two slots and starts piping when the
+second one arrives. Both waits share a single 10 second deadline; expiry closes
+everything and frees the entry.
+
+The agent dials locally *before* opening the stream, so a refused connection
+arrives as an explicit `ProxyClose{reason}` rather than as a hang.
+
+`BuildGuacParams` stops reading `srv.IPAddress` and takes the relay host and port
+instead. `IPAddress` remains in use for display and for monitors.
+
+## Wire protocol
+
+Additive only; no existing message changes shape.
+
+```protobuf
+rpc ProxyStream(stream ProxyClientMsg) returns (stream ProxyServerMsg);
+
+message OpenProxyCmd {            // ServerCommand oneof field 8
+  string proxy_id = 1;
+  uint32 port     = 2;
+}
+
+message ProxyClientMsg {
+  oneof payload {
+    ProxyOpen  open  = 1;         // first message only
+    bytes      data  = 2;
+    ProxyClose close = 3;
+  }
+}
+message ProxyOpen  { string server_id = 1; string agent_token = 2; string proxy_id = 3; }
+message ProxyServerMsg { oneof payload { bytes data = 1; ProxyClose close = 2; } }
+message ProxyClose { string reason = 1; }
+```
+
+Two implementation facts about this repo shape the above. The `pb` packages are
+**hand-written Go, not protoc output** — `vantage.proto` is documentation, and
+both `server/internal/grpc/pb` and `agent/internal/grpc/pb` are edited by hand
+and kept in sync manually. And the registered codec is JSON, so a `bytes` field
+travels as a base64 string: roughly 33% overhead on relayed traffic. That is
+accepted rather than fixed here, because introducing a second codec for one RPC
+is a larger change than this feature warrants. Relay chunks are 32 KiB.
+
+## Security
+
+**The agent only ever dials `127.0.0.1`.** The port is the only field it takes
+from the server; the host is hardcoded agent-side. A compromised control plane
+cannot use an agent to reach anything else on the customer's network. This is the
+strongest property in the design and the reason self-relay was chosen.
+
+**`proxy_id` is 32 random bytes, single-use and scoped.** On `ProxyOpen` the
+server checks three things together: the agent token hash matches that
+`server_id`, the `proxy_id` exists in the registry, and the entry's `server_id`
+and `instance_id` match the authenticated agent. Any mismatch closes the stream
+without revealing which check failed.
+
+**The listener is the exposed surface and is narrowed four ways.** It binds an
+ephemeral port; it lives at most 10 seconds unclaimed; it accepts exactly one
+connection and closes immediately afterwards; and the accepted connection's
+remote address must resolve to a host named in `GUACD_ADDR`. Without that last
+check, any other container on the Docker network could claim the session during
+the window.
+
+**Agent-offline is refused early.** `consoleConnect` checks
+`srv.Status == "active"` and returns 409 `agent_offline`, rather than letting the
+browser open a WebSocket that dies on a deadline.
+
+**Audit.** `console.opened` gains the relay port and `proxy_id`. A relay that
+expires or is refused writes `console.proxy_failed` with a reason, so a failed
+console session stops being invisible.
+
+Credentials are unchanged. Private keys and RDP passwords travel from the server
+to guacd inside the guacamole handshake and never reach the agent. The SSH and
+RDP sessions are negotiated end-to-end between guacd and the target daemon, so
+the agent relays bytes it cannot read.
+
+## Components
+
+New, server:
+
+| Unit | Responsibility |
+| --- | --- |
+| `server/internal/proxy/registry.go` | `Open`, `AttachAgent`, `AttachTCP`, expiry sweep. Pure state — no net, no gRPC, testable alone |
+| `server/internal/proxy/session.go` | One relay: listener, deadline, the `io.Copy` pair, teardown-once |
+| `server/internal/grpc/proxystream.go` | The `ProxyStream` handler: authenticate, then hand the stream to the registry. No relay logic of its own |
+
+New, agent:
+
+| Unit | Responsibility |
+| --- | --- |
+| `agent/internal/proxy/proxy.go` | `Open(ctx, client, proxyID, port)` — dial loopback, open the stream, pump bytes. No build tags; Linux and Windows share it |
+
+Changed:
+
+- `proto/vantage/v1/vantage.proto`, and both generated pb trees
+- `server/internal/services/console.go` — `BuildGuacParams(srv, relayHost, relayPort, …)`
+- `server/internal/api/console.go` — offline pre-check in `consoleConnect`; open the relay before the guacd handshake in `consoleTunnel` and close it in `OnDisconnect`
+- `agent/internal/sync/sync.go` — handle `OpenProxyCmd`, one goroutine per proxy
+- `deploy/docker-compose.yml`, `deploy/docker-compose.site.yml` — `PROXY_ADVERTISE_HOST=server`
+
+Two new optional environment variables on the server: `PROXY_ADVERTISE_HOST`
+(default `server`, the name guacd resolves the control plane by) and
+`PROXY_LISTEN_HOST` (default `0.0.0.0`).
+
+Nothing new is opened on the customer's firewall — the relay rides the agent's
+existing outbound gRPC connection.
+`docsite/docs/reference/ports-and-networking.md` and
+`docsite/docs/vantage/browser-console.md` must say so, and must state the new
+requirement that the agent be online.
+
+A secondary benefit beyond cloud: a VNC or RDP service bound only to `127.0.0.1`
+is now reachable, where a direct dial from guacd never could be.
+
+## Failure modes
+
+| Failure | Behaviour |
+| --- | --- |
+| Agent offline at connect | 409 `agent_offline` from `consoleConnect`, before any WebSocket is opened |
+| Agent never opens the stream | 10s deadline; listener closed; `console.proxy_failed{reason:"agent_timeout"}`; WebSocket closed with a message the UI surfaces |
+| Local dial refused (daemon down, wrong port) | `ProxyClose{reason}` relayed up as the same audit event, reason `dial_refused` |
+| guacd never dials | Same deadline path, reason `guacd_timeout` |
+| Bad token, unknown or foreign `proxy_id` | Stream closed with no detail leaked; `console.proxy_failed{reason:"rejected"}` |
+| Agent process dies mid-session | Stream EOF, relay torn down, console shows a disconnect |
+| CommandStream reconnects mid-session | No effect on live sessions — the relay is on its own stream. Only a new `OpenProxyCmd` needs the control stream |
+
+Teardown is guarded by `sync.Once` on both sides: both `io.Copy` goroutines
+finish, and whichever finishes second must not double-close.
+
+## Testing
+
+Written test-first.
+
+- `server/internal/proxy/registry_test.go` — the two halves pair in either
+  order; expiry frees the entry; a second claim on a used `proxy_id` is
+  rejected; a mismatched `instance_id` is rejected. No network.
+- `server/internal/proxy/session_test.go` — two `net.Pipe` halves; bytes flow
+  both ways; EOF in each direction tears down; double-close is safe.
+- `server/internal/grpc/proxystream_test.go` — the authentication matrix: valid,
+  wrong token, unknown `proxy_id`, `proxy_id` belonging to another instance.
+- `agent/internal/proxy` — a refused dial emits `ProxyClose`; the happy path
+  echoes bytes.
+- End-to-end in `server`: a fake agent plus a `net.Listen` echo server, asserting
+  bytes traverse listener → registry → stream → echo and back. This is the test
+  that would have caught the original bug.
+
+Manual verification, in this order: self-hosted SSH (proves no regression),
+cloud SSH to a private-network host, cloud RDP to a Windows agent.

+
+A self-hosted install runs unlicensed until you give it a licence. Free is a
+real tier in both deployments, and you can claim one for your install from the
+HQ portal.
+
+## What a licence is
+
+A signed file. It carries the instance UUID it belongs to, the tier, the server
+allowance, feature toggles and an expiry. The control plane verifies the
+signature locally checking a licence never contacts HQ, and a running instance
+does not need HQ to be reachable.
+
+Signing happens in exactly one place, in HQ. The control plane can only verify.
+
+## 1. Find your instance UUID
+
+In the control plane, go to **Settings → Licence**. The instance UUID is shown
+there. It is the identity your licence binds to.
+
+## 2. Link the install to your HQ account
+
+1. Sign in at [Vantage HQ](https://vantage-hq.hostxtra.co.uk). If you have no
+   account, see [Accounts and signup](../hq/accounts-and-signup.md).
+2. Choose **Link an instance**.
+3. Paste the instance UUID and give it a name you will recognise.
+
+Linking claims the UUID for your account. A UUID already linked elsewhere is
+refused with a conflict rather than silently moved.
+
+## 3. Claim Free
+
+With the instance linked, choose **Claim Free** on it. HQ issues a Free licence
+bound to that UUID and hands it back.
+
+:::info One Free per account, per deployment
+The limit is enforced per account **and** deployment, so a Free cloud instance
+does not stop you claiming Free on a self-hosted install. Both the friendly
+pre-check and the issuer apply the same rule deliberately, because a
+pre-check stricter than the issuer would refuse something that would actually
+have worked.
+:::
+
+## 4. Install the licence
+
+Download the licence from HQ and paste it in the control plane at
+**Settings → Licence**.
+
+The instance validates the signature, checks the UUID matches its own, and
+starts reporting the tier, allowance and expiry.
+
+:::warning Cloud instances cannot paste a licence
+On a cloud instance `POST /license` answers `409 cloud_managed`, and the UI
+hides the form entirely. A cloud licence is written directly by HQ. This is not
+a restriction the injection path has to work around it writes to the database,
+not through the endpoint.
+:::
+
+## Renewing
+
+Free licences are renewable from HQ within a renewal window near expiry;
+outside that window the renew call refuses. See [Free tier](../hq/free-tier.md).
+
+Pasting a licence keeps working while the current one is expired that endpoint
+is exempt from the licence check, because it is the way out of degraded mode.
+
+## Moving the install to new hardware
+
+Rebuilding produces a new instance UUID, and a licence binds to a UUID. Use
+**Relink** in HQ to move the licence across. The number of relinks per term is
+capped; the portal shows how many you have left.

+| Team members          | Granted from HQ; the instance holds a projection    | Created in the instance itself |

+| Expired Free instance | Eventually deleted, after warning                   | Never deleted                  |
+
+## Cloud
+
+You create an instance from the HQ portal and it exists a few seconds later,
+already licensed. People you grant access to get a real user inside that
+instance see [People and roles](../hq/people-and-roles.md) but HQ owns their
+password, role and existence.
+
+:::info The instance does not phone home
+A grant writes a user row into the control plane once. After that the instance
+authenticates that person entirely on its own. HQ being down does not stop
+anyone signing in to a running instance.
+:::
+
+Cloud instances on the Free tier are reaped after their licence expires, with
+warning emails first. See [Free tier](../hq/free-tier.md).
+
+## Self-hosted
+
+You run the Docker Compose stack on your own infrastructure. Nothing about the
+control plane requires an internet connection to HQ at runtime a licence is a
+signed file, verified locally.
+
+Two ways to get one:
+
+1. **Free** link the install to an HQ account and claim it
+   ([Claim a Free licence](./claim-free-licence.md)).
+2. **Paid** buy from HQ, which creates a placeholder, then paste the install's
+   real instance UUID to bind and issue
+   ([Self-hosted instances](../hq/self-hosted-instances.md)).
+
+Self-hosted users are local (or OIDC). There is no projection from HQ, and the
+three member endpoints in HQ refuse to touch a self-hosted instance at all.
+
+## Which should you pick
+
+Pick cloud if you want the thing running now and do not want to own a MongoDB.
+Pick self-hosted if your policy requires the control plane inside your own
+network, or the servers you manage cannot reach the public internet.
+
+Moving between them is a migration, not a switch instances are bound to a
+deployment at creation, and a licence binds to an instance UUID.

+
+Enrolling a machine means running one command on it. The control plane issues a
+short-lived token, the install script fetches the agent and writes a config, and
+the machine registers itself.
+
+## 1. Create the enrolment
+
+In the UI, go to **Servers → Add server**. That calls `POST /api/servers/new`,
+which generates a server ID and a pre-registration token and hands back a ready
+one-liner.
+
+:::warning The token is single-use and lives one hour
+It is the only credential in the flow, and it is spent the moment the agent
+calls `Register`. If you paste it somewhere and come back tomorrow, create a new
+enrolment instead nothing is lost by doing so.
+:::
+
+## 2. Run the one-liner
+
+### Linux
+
+```bash
+curl -fsSL "https://vantage.example.com/install?server_id=<id>&token=<token>" | bash
+```
+
+Run it as root. The script:
+
+1. Detects architecture `x86_64` and `aarch64` only; anything else exits.
+2. Asks the Gitea API for the newest `agent/v*` release.
+3. Downloads the binary and `checksums.txt`, and **verifies the SHA-256**,
+   aborting on a mismatch.
+4. Installs to `/usr/local/bin/vantage-agent`, mode `0755`.
+5. Writes `/etc/vantage/config.yaml` (directory `0700`, file `0600`) containing
+   the server ID, the pre-registration token and the gRPC host.
+6. Writes `/etc/systemd/system/vantage-agent.service` with `Restart=always`, and
+   runs `systemctl enable --now vantage-agent`.
+
+### Windows
+
+```powershell
+irm "https://vantage.example.com/install.ps1?server_id=<id>&token=<token>" | iex
+```
+
+Run from an elevated PowerShell. The agent is registered as a service through
+NSSM, with the config at `%ProgramData%\vantage\config.yaml`. There is also an
+MSI built by CI if you would rather deploy that.
+
+:::info Windows agents are second-class on purpose
+They register, heartbeat, run workflow steps and report inventory. They do
+**not** manage `authorized_keys` the key subsystem is Linux-only, and a
+Windows agent stops after the heartbeat portion of the poll.
+:::
+
+## 3. Watch it come up
+
+The server appears immediately as `pending`. Within one poll interval 30
+seconds it flips to `active`.
+
+On the machine:
+
+```bash
+systemctl status vantage-agent
+journalctl -u vantage-agent -f
+```
+
+What happens on that first run:
+
+```
+1. Load /etc/vantage/config.yaml
+2. pre_reg_token present  → register → save agent_token, clear pre_reg_token
+3. Reconnect with the permanent token
+4. Start: command stream · hourly update check · inventory · monitors
+5. Enter the key poll loop
+```
+
+After registration the config no longer contains the pre-registration token; it
+contains a permanent agent token instead. The control plane stores only the
+SHA-256 of that token, never the token itself.
+
+## 4. Confirm it works
+
+Open the server's detail page. Within a minute or two you should see:
+
+- Status `active`, with a recent last-seen timestamp.
+- Inventory CPU, memory, swap, partitions, kernel. Metrics refresh every 30
+  seconds; the full static snapshot every 15 minutes.
+- Pending OS updates, checked hourly.

+
+This installs the control plane on a host you own. Budget about fifteen minutes.
+
+## Before you start
+
+You need:
+
+- A Linux host with **Docker** and the **Compose plugin**.
+- A DNS name pointing at it. You will use it for both the web UI and, with a
+  port, for agents.
+- A reverse proxy terminating TLS in front of the web UI. gRPC on `:9090` is
+  reached directly by agents.
+- Two ports reachable from every machine you intend to manage: the web port for
+  people, and **9090** for agents.
+- Outbound access from the control plane, and from every managed machine, to
+  `gitea.hostxtra.co.uk`, which serves the agent releases.
+
+The stack itself brings MongoDB, Redis and guacd with it. You do not need to
+provide a database.
+
+## 1. Get the compose file
+
+Put `deploy/docker-compose.yml` from the repository in a working directory, for
+example `/opt/vantage`.
+
+```bash
+mkdir -p /opt/vantage/data && cd /opt/vantage
+# copy docker-compose.yml here
+```
+
+The `server` service bind-mounts `./data`, which is where workflow run logs are
+written. Create it before first boot so it is not owned by root-in-container in
+a way you did not intend.
+
+## 2. Write the environment file
+
+Create `/opt/vantage/.env`:
+
+```bash
+# The host:port agents dial. NOT the web URL this port speaks gRPC.
+GRPC_HOST=vantage.example.com:9090
+
+
+# 32 bytes as 64 hex characters. Generate with the command below.
+KEY_ENCRYPTION_KEY=
+
+# Optional: where workflow run logs are written inside the container.
+VANTAGE_WORKFLOW_LOG_DIR=/data/workflow-logs
+```
+
+Generate the encryption key:
+
+```bash
+openssl rand -hex 32
+```
+
+:::danger Keep the encryption key
+`KEY_ENCRYPTION_KEY` encrypts SSH private keys, vault secrets, OIDC client
+secrets and console credentials with AES-256-GCM. Lose it and every one of those
+becomes unreadable there is no recovery path. Back it up somewhere other than
+the server it protects, and never rotate it without a planned re-encryption.
+:::
+
+:::warning `GRPC_HOST` has no default
+The server refuses to boot without it. There is deliberately no fallback to the
+web host: that would hand every agent a port that does not speak gRPC, and the
+failure would only surface later, on each agent, as a connection error.
+:::
+
+## 3. Start the stack
+
+```bash
+docker compose up -d
+docker compose ps
+```
+
+Five services come up: `mongo`, `redis`, `guacd`, `server` and `web`.
+
+Check the server got through boot:
+
+```bash
+docker compose logs -f server
+```
+
+Boot runs database migrations, builds indexes and seeds the default workflow
+step library. Index builders for auth and settings are **fatal on failure** —
+they enforce tenant isolation, so the server would rather not start than start
+without them.
+
+## 4. Put a proxy in front
+
+Point your reverse proxy at `web` on port `3000` and terminate TLS there. The
+web app calls the REST API through a Next rewrite, so you do not need to expose
+`8080` publicly.
+
+Do **not** proxy `9090`. Agents connect to it directly over TLS.
+
+## 5. First sign-in
+
+Open your hostname in a browser. With no users in the database, you are sent to
+`/setup`.
+
+Continue with [First login](./first-login.md).
+
+## Verifying the install
+
+| Check                                          | Expected                        |
+| ---------------------------------------------- | ------------------------------- |
+| `docker compose ps`                            | five services `running`         |
+| `curl -s localhost:8080/auth/bootstrap-status` | JSON saying bootstrap is needed |
+| `nc -z your-host 9090`                         | open                            |
+| `docker compose logs server \| grep -i fatal`  | nothing                         |
+
+## Common install problems
+
+**Server exits immediately.** Almost always a missing `GRPC_HOST`. The log line
+names it.
+
+**Agents register but never go active.** They reached `:9090` for `Register` but
+cannot sustain the poll, or `GRPC_HOST` names a host they resolve differently.
+Check from the managed machine, not from the control plane host.
+
+**Secrets pages error.** `KEY_ENCRYPTION_KEY` is empty or not 64 hex characters.
+
+More in [Troubleshooting](../reference/troubleshooting.md).
+
+## What this install does not include
+
+The website, the HQ portal and this documentation site are hosted by us and are
+not part of a self-hosted install. It deliberately runs none of them, and in
+particular never holds the licence signing key.

+title: What is Vantage
+sidebar_label: What is Vantage
+---
+
+Vantage manages a fleet of servers from one place. It began as SSH key
+management and grew outwards: key assignment, scripted workflow execution,
+service monitoring, a secrets vault, a browser-based console and OS update
+management.
+
+## The pieces
+
+```mermaid
+flowchart TD
+    W["Web UI<br/>servers · keys · workflows · monitors<br/>secrets · audit · console · settings"]
+    S["Server<br/>REST :8080 · gRPC :9090<br/>MongoDB · Redis · guacd"]
+    A["Agent<br/>one per managed server<br/>Linux and Windows"]
+    W -->|REST, cookie session| S
+    S -->|gRPC over TLS| A
+    A -.->|outbound only| S
+```
+
+**The server** holds all state and does all decision-making. It exposes a REST
+API on `:8080` for the web UI and a gRPC API on `:9090` for agents. MongoDB
+stores everything durable; Redis stores sessions and nothing else.
+
+**The agent** is a single Go binary running as root on each managed server. It
+polls the control plane every 30 seconds for desired key state, and holds a
+bidirectional command stream so the server can push work run a workflow step,
+generate a key, apply updates without waiting for the next poll.
+
+**The web UI** is the operator interface. Everything it does goes through the
+REST API, which is the actual security boundary; the UI only ever makes things
+convenient.
+
+## How agents connect
+
+The agent dials **out** to the control plane. There is no inbound listener on a
+managed server, no port to open and no NAT traversal to arrange. If the machine
+can reach your Vantage host on the gRPC port, it can be managed.
+
+That direction is why `GRPC_HOST` exists as an explicit setting: the agent has
+to be told a `host:port` it can reach, and there is no safe default the server
+could guess on its behalf.
+
+## Two request patterns
+
+| Pattern                       | Used for                                                   | Why                                                                                              |
+| ----------------------------- | ---------------------------------------------------------- | ------------------------------------------------------------------------------------------------ |
+| Poll, every 30s               | desired SSH key state                                      | Key changes are not urgent, and polling survives a dropped connection with no reconnection logic |
+| Push, over the command stream | workflow steps, key generation, updates, agent self-update | Clicking Run should not wait up to 30 seconds                                                    |
+
+## Multi-tenancy
+
+Every document in the database carries an instance ID, and every query is scoped
+by it. One deployment can therefore host many independent tenants. On a
+self-hosted install that mechanism is still there you simply have one tenant.

+
+Vantage HQ, at `vantage-hq.hostxtra.co.uk`, is where you manage the **account**
+behind your instances: your team, your instances, their licences and billing.
+
+## An account is a team, not a person
+
+One account holds many people and many instances. Everyone in it has an account
+role:
+
+| Role     | Can                                                    |

+| `admin`  | Invite people, create instances, grant instance access |
+| `member` | Read what the account holds                            |
+
+Reading is open to any signed-in member. Every mutation except changing your own
+password requires `owner` or `admin`. Billing is owner-only.
+
+The three words are the same as the control plane's roles, on purpose but they
+are separate things. Your account role governs the portal; your role _inside_ an
+instance governs that instance.
+
+## Signing up
+
+Signup is **account-first**. Creating an account creates the account and you;
+it does not create a Vantage instance. Nothing exists in any control plane until
+you later create or link one.
+
+1. Go to the signup form.
+2. Enter your name, email and a password.
+3. Check your email and click the verification link.
+
+:::info Verify before you can sign in
+An unverified account gets a distinct "check your email" message rather than a
+generic authentication failure the address is already known to be yours, so
+there is nothing to protect by being vague.
+:::
+
+Verification links are valid for **24 hours**. The token is 32 random bytes and
+only its SHA-256 hash is stored, so a leaked database yields no working links.
+
+If the verification email cannot be sent, the signup is rolled back rather than
+left stranded retry rather than assuming a half-created account is in the way.
+
+## Signing in
+
+Email and password. The session is a cookie, separate from the control plane's:
+signing in to HQ does not sign you in to an instance, and vice versa.
+
+## What comes next

+## The portal layout
+
+Three destinations: **Overview**, **People**, **Billing**.
+
+Settings lives in the account menu rather than the nav, because it is your
+password rather than a place. The appearance toggle is there too.
+
+Overview lists your instances. Each is one record, closed to a row and open to
+its licence contents, members and actions. It opens by default when it is your
+only instance or when it needs attention, and your manual choice is remembered.
+
+There is deliberately no "your plan" card in the sidebar: tier, limits and
+expiry belong to a **licence**, and a licence belongs to one instance. An
+account with a Free cloud instance and a Professional self-hosted one has no
+single plan to show.

+Paid plans are billed through **Paddle**, which is the merchant of record. Your
+invoice, your card details and your tax handling are all Paddle's; HQ holds a
+customer reference and nothing sensitive.
+
+Billing is **owner-only**.
+
+## Buying
+
+### Cloud
+
+Open the instance, change its configuration to what you want, and check out.
+Checkout runs in the browser.
+
+### Self-hosted
+
+**Buy self-hosted**, then bind the purchase to your install's UUID. See
+[Self-hosted instances](./self-hosted-instances.md).
+
+## What you are buying
+
+A subscription's line items are the configuration: the plan base, the metered
+server count above the base, and any per-instance features. Changing the
+configuration changes the line items.
+
+## Changing configuration
+
+**Instance → Configuration**, adjust servers or features, and save.
+
+- **Increases** take effect when the payment confirms.
+- **Reductions** are scheduled for the end of the term. The portal shows the
+  date and the new value.
+
+## The customer portal
+
+**Billing → Manage** mints a Paddle customer-portal session where you can
+update your payment method, see invoices and cancel.
+
+## How a licence follows a payment
+
+```mermaid
+flowchart LR
+    C["Checkout / change"] --> P["Paddle"]
+    P -->|signed webhook| H["HQ"]
+    H --> G["Entitlement: desired → granted"]
+    G --> L["Licence signed from granted"]
+```
+
+The webhook is the **only** issuing path for paid plans. It is signature
+verified, processed exactly once, and resolved from the subscription's _current_
+line items so a webhook that arrives out of order still produces the right
+answer rather than replaying a stale state.
+
+A licence is signed from **granted** only. A checkout you abandon changes
+nothing.
+
+## Cancelling and failed payments
+
+Cancelling, or a payment going past due, takes **no immediate licence action**.
+Your licence runs to its grace-padded expiry and then lapses normally. There is
+no mid-term cut-off.
+
+For a cloud Free instance, lapsing eventually leads to deletion see
+[Free tier](./free-tier.md). Paid instances are not reaped.
+
+## Renewals
+
+At renewal the subscription bills again and the licence is reissued for the new
+term. It is also the only moment a scheduled **reduction** takes effect.
+
+Self-hosted customers: download and paste the reissued licence. Cloud customers:
+nothing to do.
+
+## Free is not in Paddle at all
+
+Free has no subscription, no £0 line item and no Paddle record. It has its own
+renewal, in the portal. An account only acquires a Paddle customer reference
+with its first paid purchase.

+A cloud instance is a Vantage control plane we run for you, reachable at
+`<your-slug>.vantage.hostxtra.co.uk`.
+
+## Creating one
+
+1. **Overview → New instance**.
+2. Choose a name and a slug.
+3. Create.
+
+The instance is provisioned with you as its owner, and a Free licence is issued
+immediately. The owner user inside it gets your HQ password hash **copied**, not
+shared see [People and roles](./people-and-roles.md).
+
+### Slugs
+
+The slug becomes your hostname label, so it is lowercase, and some names are
+reserved. Pick something you can say on a phone call.
+
+:::warning One Free instance per account, per deployment
+Creating a second Free cloud instance is refused. If you want another, it needs
+a paid plan or free up the first.
+:::
+
+## Using it
+
+Sign in at your instance's hostname with the email and password you use for HQ.
+It is a normal Vantage install from that point: see
+[Getting started](../getting-started/first-login.md) and the
+[Vantage](../vantage/servers.md) section.
+
+The instance does not depend on HQ at runtime. HQ being unreachable does not
+affect anyone signing in or any agent syncing.
+
+## The instance record
+
+Each instance on Overview is one record. Closed, it is a row. Open, it shows:
+
+- **Licence contents** tier, server allowance, features, expiry.
+- **Members** who has access and with what instance role.
+- **Actions** grant access, change configuration, renew.
+
+## Members
+
+Granting access writes a real user into the instance. Covered fully in
+[People and roles](./people-and-roles.md).
+
+## Changing what it can do
+
+Server allowance and per-instance features (browser console, single sign-on) are
+part of the instance's **entitlement**. Changing it goes through billing see
+[Licensing and entitlements](./licensing-and-entitlements.md) and
+[Billing](./billing.md).
+
+## Renaming
+
+The display name is free to change. The slug is the hostname and is not
+casually changed ask support if you need it.
+
+## What happens if the licence lapses
+
+A cloud instance whose Free licence expires enters degraded mode, then, after a
+grace period, the instance and all its data are deleted. Warning emails go out
+first. See [Free tier](./free-tier.md).
+
+Paid instances do not get reaped by that mechanism. A cancelled subscription
+runs to its grace-padded expiry and then lapses.
+
+## Deleting
+
+Ask support. Deletion is performed by the control plane, not by HQ the control
+plane is the only service that knows which collections carry the instance ID,
+and duplicating that list into HQ would be a list that drifts.

+
+## One per account, per deployment
+
+The limit is enforced per account **and** deployment. A Free cloud instance does
+not prevent a Free self-hosted one they are separate slots.
+
+## Free is outside Paddle
+
+There is no subscription, no £0 line item and no invoice. Your account acquires
+a Paddle customer reference only with its first paid purchase.
+
+## Renewing
+
+Free licences have a term and must be renewed from the portal.
+
+- The renew button appears **7 days before expiry**.
+- It stays available **after** expiry, right up until the instance is reaped —
+  so the same button rescues a lapsed instance rather than needing a second
+  mechanism.
+- Renewing outside that window is refused, and the message names the date it
+  opens.
+
+:::tip Put the expiry in a calendar
+Warning emails go to the account address. If nobody watches that inbox, a Free
+cloud instance can lapse and eventually be deleted without anyone noticing.
+:::
+
+## What happens when it lapses
+
+**Self-hosted:** the instance goes into degraded mode after the grace period and
+stays that way. Nothing is deleted, ever.
+
+**Cloud:** the instance goes into degraded mode, and after a further period the
+instance **and all its data are deleted**. Warning emails are sent first, naming
+the date.
+
+:::danger Deletion is permanent
+There is no restore. If a cloud Free instance is approaching that date and you
+want to keep it, renew it, or move it to a paid plan.
+:::
+
+Deletion is carried out by the control plane rather than by HQ. HQ sends the
+warnings because it knows the billing address; the control plane performs the
+delete because it is the only service that knows which collections carry the
+instance ID.
+
+## Moving off Free
+
+Change the instance's configuration to a paid tier and check out. Your data
+stays where it is a tier change reissues a licence, it does not rebuild
+anything.
+
+## Relinks
+
+Free instances get the same relink allowance as paid ones: three per term. That
+cap exists to put a human in front of a fourth attempt, not to obstruct a
+genuine rebuild.

+
+A **licence** is a signed statement of what one instance may do. An
+**entitlement** is the configuration a licence is cut from.
+
+## Tiers
+
+Three tiers, in both deployments. The allowances are identical across cloud and
+self-hosted what differs is the term on offer, not what you get.
+
+|                       | Free      | Professional | Enterprise            |
+| --------------------- | --------- | ------------ | --------------------- |
+| Servers (base)        | 3         | 3            | 10                    |
+| Monitors              | 3         | unlimited    | unlimited             |
+| Secret groups         | 1         | unlimited    | unlimited             |
+| Notification channels | 1         | unlimited    | unlimited             |
+| Audit retention       | 30 days   | 365 days     | unlimited             |
+| Support               | Community | Email, 24×5  | Email and phone, 24×7 |
+
+The server count is **metered**: the base allowance comes with the tier, and you
+buy additional servers on top. That is why Professional shows a real number
+rather than "unlimited" the number you actually have is the one in your
+entitlement.
+
+## Features
+
+Two are per-instance toggles rather than tier bundles:
+
+| Feature   | What it enables                                                           |
+| --------- | ------------------------------------------------------------------------- |
+| `console` | The [browser console](../vantage/browser-console.md)                      |
+| `oidc`    | Per-instance [single sign-on](../vantage/settings.md#single-sign-on-oidc) |
+
+No tier includes them by default; you enable them on the instances that need
+them.
+
+## Entitlements: desired and granted
+
+Each instance has one entitlement row holding two configurations:
+
+|             | Meaning                      |
+| ----------- | ---------------------------- |
+| **Desired** | What you last asked for      |
+| **Granted** | What a payment has confirmed |
+
+Checkout is built from **desired**. A licence is only ever signed from
+**granted**. An abandoned checkout therefore leaves a desired that reached
+nothing and changed nothing.
+
+### Increases and reductions
+
+An increase takes effect when payment confirms, and the entitlement is promoted
+desired → granted.
+
+A **reduction** is scheduled rather than immediate: you keep what you paid for
+until the end of the term, and the portal shows the date it drops. The collapse
+happens at renewal.
+
+## What a licence carries
+
+Instance UUID, deployment, tier, resolved limits, features, term and expiry —
+all signed.
+
+Two properties follow from that:
+
+- **A licence is bound to one instance UUID.** Moving it takes a
+  [relink](./self-hosted-instances.md#relinking).
+- **A licence is a snapshot.** Editing a plan later never rewrites an issued
+  licence, the same way editing a workflow step never rewrites a past run.
+
+Verification is local. Your instance does not call HQ to check a licence, and
+signing happens only in HQ.
+
+## Expiry and grace
+
+Expiry is padded with a grace period. Past that, the instance goes into degraded
+mode: it keeps running and keeps your data, but stops letting you do everything.
+
+The way out is a current licence renew or purchase, then paste it (self-hosted)
+or let it be written for you (cloud).
+
+## Server limits in practice
+
+When you exceed your server allowance, enrolling another one is refused. The
+existing fleet is unaffected. Raise the allowance in the portal, or remove a
+server you are not using.
+
+## Legacy tiers
+
+An older `self_hosted` tier is mapped forward to self-hosted Professional
+wherever it appears. Nothing needs doing about it.

+
+Two separate things live here: who is in your **account**, and who has access to
+each **instance**.
+
+## Account members
+
+**People** lists everyone in the account.
+
+| Role     | Can                                             |
+| -------- | ----------------------------------------------- |

+| `member` | Read                                            |
+
+Owners and admins invite; billing is owner-only.
+
+### Inviting someone
+
+1. **People → Invite**.
+2. Enter their email and pick a role.
+3. They receive a link and set their own password at `/accept-invite`.
+
+:::info Why you cannot set their password
+An invitation creates a person with an **empty password hash**, which cannot
+authenticate at all until they set one. If the inviter chose it, that password
+would be a shared credential to every instance the person is later granted
+access to.
+
+The verification endpoint knows the difference: a token belonging to a
+passwordless person reports that a password is needed and is left unspent, so
+the link still works when they get to it.
+:::
+
+### Removing someone
+
+Removing them from the account removes their portal access. See below for what
+happens to their instance access.
+
+## Instance access
+
+Granting access to a **cloud** instance creates a real user inside that
+instance's control plane, with `auth_source: "hq"`.
+
+```mermaid
+flowchart LR
+    P["HQ account member"] -->|grant| U["Control-plane user<br/>auth_source: hq"]
+    U --> I["The instance authenticates<br/>this user like any other"]
+```
+
+The instance authenticates that user exactly as it authenticates anyone else,
+with **no runtime dependency on HQ**. Revoking deletes the row the control
+plane has no disabled state, and a row that exists is a row that can sign in.
+
+### Granting
+
+On an instance record, **Members → Add**, choose an account member and an
+instance role (`owner`, `admin`, `member`).
+
+One person holds at most one user per instance, so granting twice is refused
+rather than quietly creating a second user.
+
+### Roles inside an instance
+
+Independent of the account role. Someone can be an account `member` and an
+instance `owner`, or the reverse.
+
+### Revoking
+
+Removes the user from the instance immediately. Any live session ends with the
+session, since the user row backing it is gone.
+
+:::warning Self-hosted instances cannot be granted from HQ
+All three member endpoints refuse when the instance is self-hosted. Manage those
+users in the instance itself, at **Settings → Access**.
+:::
+
+## Passwords
+
+Your HQ password is the single source of truth for every user projected from it.
+Changing it in the portal rehashes it and copies the hash to every instance you
+have been granted.
+
+Propagation is best-effort and immediate; a background pass compares and repairs
+every 15 minutes, so a temporarily unreachable instance catches up on its own.
+
+There is no local password-change endpoint for those users in the control plane,
+so there is never a second writer for the hash.
+
+:::warning HQ-managed users are read-only in the instance
+Changing the role of, or deleting, an `hq`-sourced user inside the control plane
+is refused with `409`. Do it from the portal. The UI shows those rows read-only
+with a link back here, but the API is the boundary; the UI is the courtesy.

+A self-hosted instance is your install, licensed through HQ. HQ never touches
+it: it issues a signed file that your install verifies locally.

+## Free
+
+Install first, then link and claim. Step by step in
+[Claim a Free licence](../getting-started/claim-free-licence.md).
+

+    D --> E["Licence issued<br/>bound to that UUID"]
+```
+
+1. **Overview → Buy self-hosted**, choose tier, term and configuration.
+2. Complete checkout. HQ creates a **placeholder** instance in state
+   `awaiting_link` with no licence attached.
+3. [Install Vantage](../getting-started/self-hosted-install.md) if you have not
+   already, and find its instance UUID at **Settings → Licence**.
+4. Back in HQ, open the placeholder and paste the UUID.
+5. The licence is issued, bound to that UUID. Download it and paste it into your
+   install.
+
+:::info Why there is a placeholder at all
+A licence binds to an instance UUID, and at the moment of payment that UUID may
+not exist yet. Issuing early would mean issuing to nothing; refusing to sell
+until you had installed would be the wrong order. The placeholder holds the
+purchase until there is something to bind to.
+:::
+
+## Linking an existing install
+
+If the install already exists, **Link an instance** takes the UUID directly. A
+UUID already claimed by another account is refused with a conflict.
+
+## Relinking
+
+Rebuilding the host produces a new instance UUID, and the old licence no longer
+matches. **Relink** moves the licence to the new UUID and reissues.
+
+The number of relinks per term is capped, and the portal shows how many you have
+left. This is not meant to obstruct disaster recovery if you have exhausted
+them for a real reason, ask support.
+
+## Installing the licence
+
+Paste it at **Settings → Licence** in your install. The instance verifies the
+signature and checks that the UUID matches its own.
+
+Pasting works even while the current licence is expired that endpoint is
+exempt from the licence check, because it is the route out of degraded mode.
+
+## Keeping it current
+
+Your install does not fetch licences. When a licence is reissued renewal,
+configuration change, relink download the new one from HQ and paste it in.
+
+:::warning Nothing reminds your install
+The control plane knows only what its licence says. Expiry emails come from HQ,
+to the account's address. Make sure someone reads them.

+# Vantage documentation
+
+Vantage is a self-hosted, multi-tenant infrastructure control plane. It manages
+SSH keys, runs scripted workflows, watches services, stores secrets, opens
+browser consoles and applies OS updates across a fleet of servers.
+
+A central server drives a lightweight agent installed on each managed machine.
+The agent connects **outbound only**, so managed servers need no inbound
+firewall holes.
+
+## Where to start
+
+| If you want to                          | Read                                                            |

+## The two products
+
+**Vantage** is the control plane the thing you sign in to in order to manage
+servers. It runs either on your own infrastructure or as a cloud instance we
+run for you.
+
+**Vantage HQ** is the portal at `vantage-hq.hostxtra.co.uk` where you manage the
+account behind those instances: who is on your team, which instances exist, what
+licence each one holds and how it is billed. HQ never manages your servers, and
+a Vantage instance never depends on HQ being reachable in order to run.

+
+Agents are versioned and released independently of the control plane, and update
+themselves on command.
+
+## Checking the current version
+
+Each server's detail page shows the version it reported at its last sync.
+`GET /api/agent/latest-version` reports the newest release available.
+
+## Updating from the UI
+
+**Servers → _a server_ → Update agent** pushes `UpdateAgentCmd` with a target
+version. The agent then:
+
+1. Downloads the binary for its platform from the release.
+2. Verifies the SHA-256 against `checksums.txt`.
+3. Stops itself, replaces the binary in place, and starts again.
+
+`Restart=always` on the systemd unit is what makes the last step work.
+
+The server briefly goes `offline` and comes back within a poll interval or two.
+
+## Updating from the machine
+
+There is a dynamic update script, the counterpart to the install one:
+
+```bash
+curl -fsSL https://vantage.example.com/update | bash
+```
+
+```powershell
+irm https://vantage.example.com/update.ps1 | iex
+```
+
+It does the same download, checksum and replace, then restarts the service. Use
+this when the control plane cannot push for example, when the machine is
+reachable but its command stream is not.
+
+## Rolling out across a fleet
+
+There is no built-in bulk update. Two reasonable approaches:
+
+- Update from each server's page, a few at a time.
+- Build a [workflow](../vantage/workflows.md) whose step runs the update script,
+  and target it at the machines you want. That gives you ordering, failure
+  handling and a log.
+
+:::tip Update a canary first
+An agent that fails to start after replacing itself needs hands on that machine.
+Do one, confirm it returns to `active`, then do the rest.
+:::
+
+## Version compatibility
+
+The agent API is versioned to tolerate an agent older than the control plane. The
+reverse an agent newer than the control plane is not a case anyone tests.
+Upgrade the control plane first.
+
+Agents report their version on every poll, so a fleet running mixed
+versions is visible in the server list rather than something you have to go
+looking for.
+
+## If an update fails
+
+| Symptom                           | Cause                                                                                                                               |
+| --------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------- |
+| "Checksum mismatch"               | Interrupted download, or a proxy rewriting the body. Retry                                                                          |
+| Downloads nothing                 | The machine cannot reach `gitea.hostxtra.co.uk`                                                                                     |
+| Service will not start afterwards | Wrong architecture binary, or the file was replaced while a different service manager held it. Reinstall with the install one-liner |
+
+Reinstalling is always safe: the config file is left alone, so the agent comes
+back with the same identity and token.

+nowhere in the database. Restore the database without it and every one of those
+values is permanently unreadable.
+
+Store the key somewhere other than the server it protects.
+:::
+
+## Backing up MongoDB
+
+With the bundled Mongo container:
+
+```bash
+docker compose exec -T mongo mongodump --archive --gzip --db vantage \
+  > /backups/vantage-$(date +%F).archive.gz
+```
+
+Restoring:
+
+```bash
+docker compose exec -T mongo mongorestore --archive --gzip --drop \
+  < /backups/vantage-2026-07-28.archive.gz
+```
+
+`--drop` replaces existing collections. Stop the `server` container first, so
+nothing writes during the restore.
+
+## Backing up the environment file
+
+```bash
+cp /opt/vantage/.env /secure-location/vantage.env
+```
+
+Treat it as a credential in its own right it holds the encryption key.
+
+## Run logs
+
+Workflow run logs live in the `./data` bind mount, not in the database. They are
+swept on the retention schedule anyway, so most people do not back them up. If
+you keep them for compliance, set retention to `0` (forever) and include the
+directory.
+
+## What a restore gives you
+
+Everything: fleet, keys, assignments, workflows and their history, monitors and
+incidents, secrets, settings and the audit log.
+
+What it does **not** do is reconcile the world. After a restore:
+
+- Agents reconnect with their existing tokens, since the token hashes are in the
+  database.
+- If the restore is older than an enrolment, that server's token hash is missing
+  and the agent will fail to authenticate re-enrol it.
+- The next agent poll rewrites `authorized_keys` to match the restored desired
+  state, which may remove keys added since the backup.
+
+## A workable schedule
+
+| What              | When                                                  |

+Upgrading the control plane is a pull and a recreate. Agents are versioned and
+upgraded separately see [Agent updates](./agent-updates.md).
+
+:::info Cloud instances upgrade themselves
+This page is for self-hosted installs. If your instance is hosted by us, there
+is nothing here for you to do.
+:::
+
+## Upgrade
+
+```bash
+cd /opt/vantage
+docker compose pull
+docker compose up -d --remove-orphans
+```
+
+`--remove-orphans` clears containers for services that no longer exist in the
+Compose file, which is what leaves a stale container running after a service is
+renamed or removed.
+
+## What happens on boot
+
+1. **Migrations** run, recording markers so each runs once.
+2. **Indexes** are ensured. Auth and settings index builders are fatal on
+   failure; secret and workflow ones only warn.
+3. **Default steps** are reseeded from the image, overwriting the `default`
+   library which is why those steps are read-only.
+
+Watch it:
+
+```bash
+docker compose logs -f server
+```
+
+## Before you upgrade
+
+- **Back up MongoDB.** See [Backups](./backups.md). Migrations are one-way.
+- **Read the release notes** for anything about migrations or environment
+  variables.
+- **Check your `.env`** still supplies everything required. A newly required
+  variable stops the boot rather than defaulting to something unsafe.
+
+## Downgrading
+
+There is no automatic downgrade. Migrations do not roll back, so returning to an
+older image means restoring the database backup taken before the upgrade. This
+is the reason the backup is not optional.

+The stack is not designed for it. `docker compose up -d` recreates the server
+container, which is a short interruption:
+
+- Agents reconnect on their own they retry, and the poll loop is idempotent.
+- Workflow runs in progress lose their command stream. Steps already dispatched
+  finish on the agent, but their results have nowhere to go. **Do not upgrade
+  during a run.**
+- Sessions survive, because they live in Redis rather than in the server.
+
+## After upgrading
+
+- Confirm every service is `running`.
+- Confirm servers return to `active` within a couple of poll intervals.
+- Open a page that touches encryption a secret group to confirm
+  `KEY_ENCRYPTION_KEY` came through.

+
+## Startup sequence
+
+```
+1. Load the config
+2. pre_reg_token present → register → save agent_token,
+   clear pre_reg_token, reconnect
+3. Start: command stream · hourly update check · inventory · monitors
+4. Enter the key poll loop
+```
+
+## The poll loop
+
+```
+1. Ask the control plane for the desired key state, reporting the
+   agent version
+2. Non-Linux hosts stop here Windows agents register and heartbeat only
+3. Diff the desired keys against /root/.ssh/authorized_keys;
+   unchanged → write nothing
+4. Changed → write a temp file, rename it over the real one, chmod 0600
+```
+
+## Service management
+
+### Linux
+
+Unit at `/etc/systemd/system/vantage-agent.service`, `Restart=always`, running
+as root.
+
+```bash
+systemctl status vantage-agent
+systemctl restart vantage-agent
+journalctl -u vantage-agent -f
+```
+
+### Windows
+
+A service registered through NSSM, or installed by the MSI that CI builds.
+
+```powershell
+Get-Service vantage-agent
+Restart-Service vantage-agent
+```
+
+## Command-line flags
+
+```
+vantage-agent -generate-key
+```
+
+Generates a keypair locally. Normal operation takes no flags.
+
+## Moving an agent to a new control plane
+
+Change `server_url`, clear `agent_token`, set a fresh `pre_reg_token` from a new
+enrolment, and restart. The old control plane still holds a server record that
+will go `offline`; delete it there.
+
+## Uninstalling
+
+```bash
+systemctl disable --now vantage-agent
+rm -f /usr/local/bin/vantage-agent /etc/systemd/system/vantage-agent.service
+rm -rf /etc/vantage
+systemctl daemon-reload
+```
+
+Keys already written to `authorized_keys` remain on disk the agent is no
+longer running to remove them. Revoke first if that matters.

+
+Two things are worth reading off that diagram.
+
+**Agents connect outbound.** No inbound rule is needed on a managed server, and
+NAT is not an obstacle. The only requirement is that the machine can reach
+`GRPC_HOST`.
+
+**The console rides the agent's connection too.** guacd never dials the target
+directly; the server pushes a command down the agent's existing outbound gRPC
+stream on `9090`, and the agent relays the protocol traffic from its own
+loopback. No route from the control plane to the target's address is needed,
+and no new inbound port opens on the target — the same connection that carries
+key sync carries console traffic. This is what makes the console work for a
+machine behind NAT on a private subnet, as long as its agent is online.
+
+## What to open
+
+### On your firewall, inbound to the control plane
+
+- Your web port, from wherever people are.
+- `9090`, from every network holding managed machines.
+
+### Outbound from the control plane
+
+- `gitea.hostxtra.co.uk`, for agent releases and version checks.
+- Anything a server-run [monitor](../vantage/monitors.md) checks.
+- SMTP, if you use an SMTP notification channel.
+
+No route to the machines you intend to console is needed — that traffic rides
+the agent's existing outbound `9090` connection instead.
+
+### Outbound from a managed machine
+
+- `GRPC_HOST`.
+- `gitea.hostxtra.co.uk`, for install and self-update.
+- Its package mirrors, for OS updates.
+
+## TLS
+
+Terminate TLS for the web UI at your reverse proxy.
+
+gRPC on `9090` is reached directly by agents with `tls: true`, so that port needs
+a valid certificate for the name in `GRPC_HOST`. If you proxy it, the proxy must
+speak HTTP/2 end to end many do not by default, and the symptom is agents that
+register and then fail to hold the command stream.
+
+## Reverse proxy notes
+
+- Point the proxy at `web:3000`. The web app reaches the REST API internally, so
+  `8080` does not need publishing.
+- The console uses a **WebSocket** at `/api/console/tunnel`. A proxy that does
+  not forward upgrade headers breaks the console and nothing else.
+- Workflow log streaming is a long-lived response. A short proxy read timeout
+  truncates live logs while the run itself continues.
+
+## Air-gapped and restricted networks
+
+The control plane needs outbound access to fetch agent releases. Managed
+machines need it too, unless you distribute the agent binary yourself and write
+the config by hand the install script's only job is to do those two things.
+
+Licence verification is entirely local, so a licensed install works with no
+outbound access to HQ at all.

+
+## Multi-tenancy
+
+Every request is scoped to the instance resolved from the session. On a
+multi-tenant deployment, a request arriving at `<slug>.vantage.<tld>` also has
+its host checked against the session's instance, and a mismatch is rejected.
+
+## Errors
+
+Errors are JSON with an `error` field. Customer-facing endpoints in the HQ API
+answer `404` rather than `403` for another account's resource, because a `403`
+confirms the resource exists; the control plane's own API is single-tenant per
+session and does not need that distinction.
+
+## Admin API
+
+Vantage HQ is a separate hosted service with its own API and its own session.
+Its behaviour is described in the [Vantage HQ](../hq/accounts-and-signup.md)
+section rather than here; the two services share no session and no
+authentication.

+Symptoms, in the order people hit them.
+
+## The server will not start
+
+**Exits immediately on boot.** Almost always a missing `GRPC_HOST` the server
+refuses to start rather than guess a value that would break every agent later.
+
+**Fails during index creation.** The auth and settings index builders are fatal
+on failure by design: those unique indexes are what enforce tenant isolation,
+so starting without them is worse than not starting. Check the MongoDB user's
+permissions and whether a conflicting index already exists.
+
+**Starts, but every secret operation errors.** `KEY_ENCRYPTION_KEY` is missing
+or is not 64 hex characters.
+
+## Nobody can sign in
+
+**`/setup` appears when users already exist.** The server is pointed at a
+different database than you think. Check the database name in `MONGO_URI` —
+it comes from the URI path, not a separate variable.
+
+**Sessions do not stick.** Redis is unreachable, or the cookie is being dropped
+because the site is served over plain HTTP.
+
+**"Wrong organisation" style rejections.** The host and session guard is
+comparing the request host's label against the session's organisation. Check
+`APP_ROOT_LABEL`.
+
+**OIDC redirects and then fails.** The callback URL registered with the provider
+must match exactly. Keep one local owner account so a broken provider is not a
+lockout.
+
+## A server never becomes active
+
+Work through it in this order:
+
+1. Is the agent running? `systemctl status vantage-agent`.
+2. What does it say? `journalctl -u vantage-agent -f`.
+3. Can that machine reach the endpoint? Test `GRPC_HOST` **from the machine**,
+   not from the control plane host.
+4. Was the token already used or expired? It is single-use and lives one hour —
+   create a fresh enrolment rather than reusing the old command.
+

+## Keys are not appearing on a machine
+
+- **It is a Windows server.** Key management is Linux-only, by design.
+- **The agent is not running.** Nothing polls, nothing writes.
+- **The key is assigned but revoked.** Revocation is soft; check the assignment

+- **Fails immediately with an interpreter error.** A bash step on a Windows
+  target, or PowerShell on Linux.
+- **A value does not reach the next step.** Values pass through the file at
+  `$WORKFLOW_ENV`, one `KEY=value` per line. Declaring an output does not export
+  it.
+- **A secret is empty.** The group is not in the step's `secret_refs`, or the

+
+## What is recorded
+
+Creation, modification and deletion across the product: servers and enrolments,
+keys and assignments, workflow and step changes, runs triggered, monitors and
+channels, secret groups and reveals, console sessions opened, settings and
+member changes, licence installs.
+
+Reads are not recorded, with one deliberate exception: **revealing a secret**
+writes an event, because reading that particular thing is an act rather than a
+lookup.
+
+## What is not recorded
+
+- Sign-ins and sign-out.
+- Anything inside a console session.
+- Step output. That lives in the run log, kept under the workflow retention
+  setting rather than with the audit log.
+
+## Retention
+
+Audit events are not swept by the workflow log retention setting that setting
+governs run logs only. Audit history stays until the instance does.
+
+:::warning It is a log, not a control
+The audit log tells you what happened. It does not restrict what can happen, and
+an admin can do anything an admin can do. Use roles for restriction and the log
+for accountability.
+:::
+
+## Getting events out
+
+`GET /api/audit` returns recent events as JSON and accepts a `limit`. There is
+no streaming or push export; if you need events in a SIEM, poll that endpoint.

+
+An SSH, RDP or VNC session in a browser tab, with no client software and no
+inbound port on the target beyond the one the protocol already uses.
+
+Protocol handling is Apache Guacamole's the control plane proxies a WebSocket
+to a **guacd** daemon and manages credentials around it.
+
+## Requirements
+
+- `guacd` running and reachable from the server. The bundled Compose stack
+  includes it; `GUACD_ADDR` defaults to `guacd:4822`.
+- `KEY_ENCRYPTION_KEY` set, since every credential involved is stored encrypted.
+- The target's **agent must be online**. Console traffic is relayed over the
+  agent's existing outbound connection, so the control plane never needs a route
+  to the server's address — but it does need the agent.
+- No inbound port on the target, beyond what the protocol already listens on
+  locally. A service bound only to `127.0.0.1` works, because the agent dials
+  loopback on the target itself.
+
+## Opening a session
+
+From a server's page, choose **Console**. Then:
+
+1. The UI calls `POST /api/console/connect`, which mints a **one-time** session
+   token. If the target's agent is not connected, this fails immediately with
+   `409 agent_offline` rather than hanging.
+2. The browser opens a WebSocket to `GET /api/console/tunnel` with that token.
+3. The server marks the token consumed atomically, so a second use cannot
+   race and proxies the connection to guacd.
+
+## Credentials
+
+### SSH
+
+Authenticates with a private key stored in the [key library](./ssh-keys.md). The
+key must have its private half uploaded; a public-only key cannot open a
+session.
+
+### RDP and VNC
+
+You supply credentials when connecting. They are encrypted, **single-use**, and
+consumed when the tunnel opens. They are not retained for the next session.
+
+:::info Why single-use
+A stored console credential is a standing grant to that machine for anyone who
+can reach the endpoint. Consuming it at tunnel-open means a leaked session token
+is worth one connection at most, and only until it is used.
+:::
+
+## Session behaviour
+
+Closing the tab ends the session. There is no reconnect and no session
+persistence reopening mints a new token and a new connection.
+
+## Auditing
+
+Opening a console is an audited action, with actor, server and time. What
+happens _inside_ the session is not recorded: there is no session capture or
+keystroke log. If you need that, it has to come from the target machine.
+
+## When it does not work

+Monitors check that something is answering. Four types, two places they can run
+from, and a notification path when they stop being satisfied.
+
+## Types
+
+| Type   | Checks                                  | Options                                                                           |
+| ------ | --------------------------------------- | --------------------------------------------------------------------------------- |
+| `http` | An HTTP(S) URL                          | method, expected status, keyword that must appear in the body, allow insecure TLS |
+| `tcp`  | A host and port accept a connection     |                                                                                   |
+| `icmp` | A host answers ping                     |                                                                                   |
+| `tls`  | A certificate is valid and not expiring | warn N days before expiry                                                         |
+
+An `http` monitor with a keyword is usually the one you want for an application:
+a 200 that returns an error page still fails the keyword.
+
+## Where a check runs
+
+Every monitor has a **runner**:
+
+| Runner      | Meaning                                                        |
+| ----------- | -------------------------------------------------------------- |
+| `server`    | The control plane's scheduler performs the check               |
+| a server ID | That server's agent performs it locally and reports the result |
+
+Use `server` for anything reachable from the control plane public endpoints,
+your own front door. Use an agent for anything only reachable from inside the
+target network: a database on a private subnet, a service bound to localhost, a
+device on a management VLAN.
+
+:::tip Agent-run monitors measure what your users can't
+A check run from the control plane tells you the service is reachable from
+there. A check run on the machine tells you the process is alive. Those are
+different questions, and outages usually live in the gap.
+:::
+
+## Interval, retries and state
+
+- **Interval** how often to check.
+- **Retries** how many consecutive failures are tolerated before the state
+  flips.
+
+A monitor sits in `pending` until its first result. Failures accumulate; once
+they exceed `retries`, the monitor goes `down`, an **incident** opens and the
+attached notification channels fire. A subsequent success closes the incident.
+
+Retries are what keeps one dropped packet from paging you. Set them to at least
+`1` for anything crossing the public internet.
+
+## Notifications
+
+Attach one or more [notification channels](./notification-channels.md) to a
+monitor. Channels are shared, so one Slack destination can serve every monitor
+you have.
+
+Notification state is tracked per monitor, so a service that is down for six
+hours does not send a message per interval.
+
+## Uptime and incidents
+
+The monitor detail page shows:
+
+- **Uptime**, from hourly rollup records checks performed, how many were up,
+  and mean latency per hour. Rollups are what make the graph cheap to draw over
+  long windows.
+- **Incidents**, each with a start, a resolution and the cause recorded at the
+  moment it opened.
+
+## Disabling versus deleting
+
+Disabling stops the checks and keeps the history. Deleting removes the monitor.
+Prefer disabling for anything seasonal the uptime record is usually the part
+you wanted.

+A channel is a destination for alerts. [Monitors](./monitors.md) reference
+channels by ID, so one destination serves as many monitors as you like.
+
+Manage them at **Settings → Notifications**.
+
+## Types
+
+### Webhook
+
+Posts JSON to a URL you choose.
+
+| Setting |          |
+| ------- | -------- |

+
+```json
+{
+    "monitor": "API front door",

+    "message": "HTTP 502",
+    "time": "2026-07-28T09:14:02Z"
+}
+```
+
+Any response of 300 or above counts as a delivery failure. The request times out
+after 10 seconds.
+
+### Discord
+
+| Setting |                     |
+| ------- | ------------------- |
+| `url`   | Discord webhook URL |
+
+Posts the alert as message content.

+| `token`   | Bot token   |
+| `chat_id` | Target chat |
+

+| `from`, `to`           | Required                                             |
+| `username`, `password` | Optional; auth is skipped when the username is empty |
+
+Port `465` uses implicit TLS; anything else uses STARTTLS.
+
+Alert emails are rendered by the same email system that sends licence and
+account mail, so a monitor alert and an account email look like the same
+product.
+
+## The message
+
+Non-webhook channels all send the same one-line title:
+
+```
+[Vantage] API front door (http) is DOWN: HTTP 502
+```
+
+Recoveries read `recovered` in place of `is DOWN`. The webhook payload carries
+the same information as fields, which is the one to use if you are routing into
+something that needs to branch on status.
+
+## Testing
+
+Every channel has a **Test** button. It dispatches a fabricated down event for a
+monitor called "Test monitor", through the real delivery path so a test that
+arrives proves the credentials, the network path and the destination, not just
+the configuration form.
+
+:::tip Test after every change
+Channel settings are only exercised when something breaks, which is the worst
+time to discover a stale webhook URL. Re-test after rotating a token.
+:::
+
+## Choosing destinations
+
+- Use a **chat channel** for awareness, and make sure someone owns it.
+- Use **SMTP** where a durable record matters.
+- Use a **webhook** to reach an on-call system that does escalation properly.
+  Vantage does not do escalation, rotas or acknowledgement; a webhook into
+  something that does is the intended answer.

+Key/value pairs, grouped by name, encrypted at rest with AES-256-GCM under
+`KEY_ENCRYPTION_KEY`. Two things consume them: workflow steps, and Kubernetes
+External Secrets Operator.
+
+## Groups and values
+
+A **group** is a named bundle `prod-db`, `registry`, `acme-api`. Inside it are
+key/value pairs.
+
+Group by consumer, not by type. A group is the unit a workflow step references
+and the unit ESO reads, so a group that matches one consumer is one reference;
+a group holding everything is over-sharing to every step that needs any of it.
+
+## Managing them
+
+**Secrets → New group**, then add keys.
+
+Values are write-then-hidden. The list shows keys, never values. **Reveal** is a
+separate action on a separate endpoint, and it writes an audit event so
+looking at a secret is a recorded act.
+
+Deleting a single key and deleting the whole group are separate operations.
+
+## Using secrets in workflows
+
+Add the group name to a step's `secret_refs`. At execution the group's pairs are
+injected into the step's environment:
+
+```bash
+# secret_refs: ["registry"]
+echo "$REGISTRY_PASSWORD" | docker login registry.example.com -u "$REGISTRY_USER" --password-stdin
+```
+
+A workflow can also override `secret_refs` per step, without changing the
+library entry.
+
+:::warning A step can print its own secrets
+Injection puts values in the environment. If your script echoes them, or runs
+with `set -x`, they land in the run log which is stored on disk and readable
+in the UI. Vantage does not scrub step output.
+:::
+
+## Kubernetes External Secrets Operator
+
+`GET /api/secrets/:group/values` returns a group's pairs for ESO, authenticated
+with a **bearer token** rather than a session.
+
+1. Generate the token at **Settings → Integrations**. It is shown once; only its
+   SHA-256 is stored.
+2. Put it in a Kubernetes secret.
+3. Point an ESO `SecretStore` at the endpoint with that bearer token.
+
+The token is rotatable: generating a new one replaces the stored hash and
+invalidates the old one immediately.
+
+:::danger This token reads every group
+It is instance-wide, not scoped to one group. Treat it as a credential to the
+whole vault: store it as a secret in the cluster, never in a manifest in git,
+and rotate it when anyone with access leaves.
+:::
+
+## What the vault is not
+
+- **Not a password manager.** There is no sharing, expiry or per-user
+  visibility. Anyone who can sign in and reveal, can reveal.
+- **Not versioned.** Overwriting a value loses the previous one.
+- **Not recoverable without the key.** If `KEY_ENCRYPTION_KEY` is lost, so is
+  every value. Back it up separately from the database.

+The fleet. Every managed machine runs an agent that connects outbound to the
+control plane, and everything else in Vantage keys, workflows, monitors,
+consoles targets these records.
+
+## Enrolling a server
+
+Covered step by step in [Add your first server](../getting-started/first-server.md).
+In short: **Servers → Add server** issues a single-use, one-hour token and shows
+a one-liner to run as root on the target machine.
+
+## Lifecycle
+
+| Status    | Meaning                                             |
+| --------- | --------------------------------------------------- |
+| `pending` | Enrolment created; the agent has not registered yet |
+| `active`  | The agent registered and is syncing                 |
+| `offline` | Last-seen passed the threshold                      |
+
+The offline sweep runs every two minutes, so a machine that has just gone away
+takes a little while to be marked as such. That delay is intentional a single
+missed poll is not an outage.
+
+## The server detail page
+
+### Keys
+
+Which SSH keys are assigned to this machine, and their state. See
+[SSH keys](./ssh-keys.md).
+
+### Inventory
+
+Agents report:
+
+| Data                                     | Refreshed        |
+| ---------------------------------------- | ---------------- |
+| CPU, memory, swap, load                  | every 30 seconds |
+| Partitions, kernel, full static snapshot | every 15 minutes |
+
+The two carry separate timestamps, so a stale static snapshot beside fresh
+metrics is normal rather than a fault.
+
+### OS updates
+
+Agents check for pending package updates hourly and report the count. From the
+server page you can:
+
+- **Apply updates** pushes `ApplyUpdatesCmd` down the command stream. The
+  agent runs the platform's package manager and reports back.
+- **Update agent** pushes `UpdateAgentCmd` with a target version; the agent
+  downloads the release, verifies it and replaces itself. See
+  [Agent updates](../operations/agent-updates.md).
+
+:::warning Applying updates is not scheduled or staged
+It runs now, on that machine. If you need ordering, health gates or a canary,
+build it as a [workflow](./workflows.md) instead that is what workflows exist
+for.
+:::
+
+### Console
+
+Opens a browser SSH, RDP or VNC session. See [Browser console](./browser-console.md).
+
+## Windows servers
+
+Windows agents register, heartbeat, run workflow steps and report inventory.
+They do not manage `authorized_keys` the poll loop stops after the heartbeat
+on any non-Linux host. This is a deliberate scope decision, not a gap being
+worked on.
+
+## Removing a server
+
+Deleting the server record removes it from the fleet. It does **not** uninstall
+the agent, which will keep trying to sync and failing. Uninstall it on the
+machine too:
+
+```bash
+systemctl disable --now vantage-agent
+rm -f /usr/local/bin/vantage-agent /etc/systemd/system/vantage-agent.service
+rm -rf /etc/vantage
+systemctl daemon-reload
+```
+
+Keys previously written to `authorized_keys` stay on disk, because the agent is
+no longer running to remove them. Revoke and let the agent apply the change
+**before** you delete the server if that matters to you.
+
+## Agent tokens
+
+Each server has its own token. The control plane stores only its SHA-256; the
+plaintext exists in the agent's `0600` config and nowhere else. There is no way
+to read a token back out of the control plane if one is lost, re-enrol the
+machine.

+One page, three groups: **Access**, **Monitoring** and **Integrations**. Plus
+the licence, which has its own page.
+
+Settings require the `owner` or `admin` role.
+
+:::info Where instance settings went
+Members and single sign-on used to live at `/settings/instance`. They are now
+the Access group at the top of this page splitting "who can sign in" from "how
+this instance behaves" produced two half-pages and a nav entry nobody could
+distinguish from Settings. The old path still redirects.
+:::
+
+## Access
+
+### Members
+
+Add, remove and re-role the people who can sign in.
+
+| Role     | Can                                                  |
+| -------- | ---------------------------------------------------- |
+| `owner`  | Everything                                           |
+| `admin`  | Everything except owner-only settings                |
+| `member` | Servers, keys, workflows, monitors, secrets, console |
+
+Local members authenticate with email and a bcrypt-hashed password.
+
+#### Members managed by Vantage HQ
+
+On a cloud instance, people granted access from the HQ portal appear here as
+read-only rows with a link to the portal.
+
+:::warning HQ-managed users cannot be edited locally
+Changing the role of, or deleting, an `hq`-sourced user is refused with `409`.
+HQ owns their role, their password and whether they exist at all a local
+change would be overwritten by the next sync and would leave two writers for one
+password hash. Manage them from [People and roles](../hq/people-and-roles.md).
+:::
+
+### Single sign-on (OIDC)
+
+Configured per organisation:
+
+| Field         |                              |
+| ------------- | ---------------------------- |
+| Issuer        | Your provider's issuer URL   |
+| Client ID     |                              |
+| Client secret | Stored AES-256-GCM encrypted |
+
+Sign-in then goes `/auth/oidc/start` → your provider → `/auth/oidc/callback`.
+
+Local and OIDC users coexist. Keep at least one local owner: if the provider is
+misconfigured or unreachable, a local account is the way back in.
+
+## Monitoring
+
+- **Alert defaults** for monitors.
+- **Notification channels** their own page. See
+  [Notification channels](./notification-channels.md).
+
+## Integrations
+
+### Workflow log retention
+
+How long run logs are kept.
+
+| Value    | Meaning        |
+| -------- | -------------- |
+| unset    | 30 days        |
+| a number | that many days |
+| `0`      | forever        |
+
+### ESO read token
+
+The bearer token External Secrets Operator uses to read secret groups. Shown
+once, stored as a SHA-256 hash, rotatable. See
+[Secrets](./secrets.md#kubernetes-external-secrets-operator).
+
+## Licence
+
+`/settings/license` shows the deployment, tier, server allowance, enabled
+features and expiry.
+
+On **self-hosted**, paste a licence here. This works even while the current
+licence is expired that is the way out of degraded mode.
+
+On **cloud**, there is no paste form. The endpoint answers `409 cloud_managed`,
+because a cloud licence is written by HQ directly. The page links to the portal
+instead.
+
+See [Licensing and entitlements](../hq/licensing-and-entitlements.md).
+
+## Sessions
+
+Sessions are an opaque token in the `km_session` cookie, held in Redis with a
+24-hour TTL. There is no per-session management UI; restarting Redis signs
+everyone out and affects nothing else.
+
+## Host and organisation guard
+
+On a multi-tenant deployment, a request to `<slug>.vantage.<tld>` resolves the
+organisation from the slug and rejects a session belonging to a different one.
+The label it looks for comes from `APP_ROOT_LABEL`.
+
+:::warning A wrong `APP_ROOT_LABEL` disables the guard
+It does not fail loudly it simply stops matching, and the host check stops
+protecting anything. If you serve the UI on a custom domain, set it to match.

+
+Vantage holds a library of public keys and decides, per server, which ones
+belong in `/root/.ssh/authorized_keys`. The agent makes the file match.
+
+:::info root only
+Vantage manages `/root/.ssh/authorized_keys` and nothing else. There is no
+per-user key management. The agent runs as root because writing that file
+requires it.
+:::
+
+## Adding a key
+
+### Upload one you already have
+
+**Keys → Add key**, paste the public half. Vantage stores the public key and its
+fingerprint, and never needs the private half for this path.
+
+### Generate one on a server
+
+Vantage can have an agent generate a keypair on a managed machine
+(`GenerateKeyCmd` over the command stream). The public half comes back to the
+library. You may optionally upload the private half too, in which case it is
+stored **AES-256-GCM encrypted** under `KEY_ENCRYPTION_KEY`.
+
+The JSON representation of a key exposes only `has_private_key` and
+`has_passphrase` never the material. Retrieving a stored private key is its
+own endpoint and its own audit event.
+
+:::tip Why store a private key at all
+The [browser console](./browser-console.md) needs one to open an SSH session. If
+you are not using the console, do not upload private halves.
+:::
+
+## Assigning
+
+Assign a key to one or more servers. Within one poll interval 30 seconds the
+agent picks up the change.
+
+## Revoking
+
+Revocation is **soft**: the assignment gets a `revoked_at` timestamp rather than
+being deleted, so the history of who had access to what, and when, survives.
+
+The agent treats a revoked assignment as "not desired" and removes the line from
+`authorized_keys` on its next sync.
+
+:::warning Revoking does not close open sessions
+It removes the key from the file. An SSH session already established stays up
+until it ends. Kill sessions on the machine if that matters.
+:::
+
+## What the agent actually does
+
+Each poll:
+
+1. The control plane returns the desired set of public keys for that server.
+2. The agent reads `/root/.ssh/authorized_keys` and computes fingerprints.
+3. **If the sets match, it writes nothing.** No disk churn on unchanged state,
+   which is most polls.
+4. If they differ, it writes a temporary file, then `os.Rename()`s it over the
+   real one and sets mode `0600`.
+
+The rename is atomic, so a machine that dies mid-write keeps the old file
+intact. There is no window in which `authorized_keys` is truncated or partial.
+
+:::danger Vantage owns the whole file
+The agent rewrites `authorized_keys` to match the desired set. Keys added by
+hand on the machine are removed on the next change. If a key must survive, put
+it in Vantage.
+:::
+
+## Recovering from a lockout
+
+If you have removed every key from a machine and cannot get in, you still have
+the console provided a private key is stored or out-of-band access from your
+hosting provider. Vantage has no backdoor and does not keep a break-glass key.

+title: Workflows and steps
+sidebar_label: Workflows
+---
+
+A **step** is a reusable script with declared inputs, outputs and secret
+references. A **workflow** composes steps in order and targets a set of servers.
+Running one dispatches the steps to each target's agent and streams the output
+back live.
+
+## Steps
+
+A step has:
+
+| Field                 | Meaning                                         |
+| --------------------- | ----------------------------------------------- |
+| `name`, `description` | Library identity                                |
+| `interpreter`         | `bash` or `powershell`                          |
+| `script`              | The body                                        |
+| `declared_inputs`     | Named parameters with defaults and descriptions |
+| `declared_outputs`    | Names this step promises to export              |
+| `secret_refs`         | Vault entries injected as environment variables |
+
+### Passing values between steps
+
+Each step runs with `WORKFLOW_ENV` set to a file path. Anything written there as
+`KEY=value` becomes an environment variable for the **later steps of the same
+run on the same server**.
+
+```bash
+HOSTNAME=$(hostname)
+echo "$HOSTNAME"
+echo "HOSTNAME=$HOSTNAME" >> $WORKFLOW_ENV
+```
+
+That is the whole mechanism. `declared_outputs` documents what a step exports so
+the designer can show it; the file is what actually carries the value.
+
+### Secrets
+
+List a vault group in `secret_refs` and its key/value pairs are injected as
+environment variables when the step runs. They are not written to the run log
+unless your own script echoes them. See [Secrets](./secrets.md).
+
+### The workspace
+
+Every run gets a per-run working directory on each target. Steps share it, so
+one step can leave a file for the next. The agent removes it at the end of the
+run (`CleanupWorkspaceCmd`).
+
+Do not use it for anything that must outlive the run.
+
+## Default steps
+
+A small library is seeded into every organisation at boot from the image, so a
+new install is not staring at an empty page.
+
+:::warning Default steps are read-only
+Editing or deleting one is refused with `409`. Seeding rewrites them on every
+boot, so an edit would silently revert and a delete would come back at the next
+restart refusing is the honest answer.
+
+To customise one, use the per-step **script override** in the workflow designer,
+which belongs to that workflow and is not touched by seeding. To add to the
+shared library permanently, a file has to be committed to the repository and the
+server image rebuilt.
+:::
+
+The UI mirrors this the step modal opens read-only and Delete is hidden but
+the API is the boundary; the UI is the courtesy.
+
+## Building a workflow
+
+1. **Workflows → New**.
+2. Add steps in order from the library.
+3. Set inputs per step.
+4. Set failure behaviour per step.
+5. Choose target servers.
+
+### Failure behaviour
+
+| `on_failure` | Effect                                                          |
+| ------------ | --------------------------------------------------------------- |
+| `stop`       | Abort this server's run. Other servers continue                 |
+| `continue`   | Record the failure, run the next step anyway                    |
+| `retry`      | Re-run the step up to `max_retries`, then treat it as a failure |
+
+### Per-step overrides
+
+A workflow can override a step's script or its secret references without
+touching the library entry. This is how you adapt a default step, and it is
+scoped to that workflow.
+
+## Running
+
+**Run** snapshots the resolved steps into the run record and dispatches each step
+to the target's agent over the command stream no waiting for the next poll.
+
+:::info Runs freeze their steps
+The snapshot is why editing a step tomorrow never rewrites what happened today.
+A run shows the script that actually executed, not the current library version.
+:::
+
+Targets run **in parallel**; steps within one server run **in order**.
+
+## Watching a run
+
+Step stdout and stderr stream back as chunks, are appended to a log file on the
+server, and the UI follows them live. Each step records status, attempts, exit
+code and its exported environment.
+
+**Cancel** stops a run in progress. Steps already running on an agent finish;
+nothing further is dispatched.
+
+## Log retention
+
+Run logs are swept on a schedule set by `workflow_log_retention_days` in
+Settings:
+
+| Value    | Meaning        |
+| -------- | -------------- |
+| unset    | 30 days        |
+| a number | that many days |
+| `0`      | keep forever   |
+
+## Import and export
+
+Steps export to a JSON file (`vantage.step/v1`) and import back, which is how
+you move a step between instances or keep one in version control. There is also
+a parse endpoint that turns a pasted script into a draft step by reading its
+declared inputs and outputs.
+
+## Practical notes
+
+- A step is a script. It runs as root, on the target, with no sandbox. Review
+  what you import.
+- Keep steps small and single-purpose; compose them in the workflow. That is
+  what makes the library reusable rather than a folder of near-duplicates.
+- PowerShell steps only make sense on Windows targets and bash steps on Linux
+  ones. Nothing stops you targeting the wrong one; the step simply fails.
