feat: SSO group autocomplete for per-host SSO allow-lists (v1.34.0)

The per-host "Allowed groups" field suggested only local groups,
permission subjects and conf.auth maps. None of those can ever match an
SSO-gated host: its allow-list is checked against the `groups` claim the
SSO issues (utils/host_sso.js), so only SSO groups are candidates.

Adds a conf.sso block (url + read-only apiToken, minted by theta-suite's
bootstrap) and a cached /api/group lookup merged into the suggestions.
Degrades silently to the previous local-only list when unset, and never
fails the request.

Authenticates with `Authorization: Bearer <token>` -- the SSO's
`auth-token` header is for browser session UUIDs and rejects a minted
API token.

+## v1.34.0
+- feat: the per-host SSO **Allowed groups** field now autocompletes from the SSO directory's groups. Suggestions previously came only from local groups, permission subjects and `conf.auth` maps — none of which can match an SSO-gated host, because its allow-list is checked against the `groups` claim the SSO issues. New `conf.sso` block (`url` + read-only `apiToken`, minted by theta-suite's bootstrap); results are cached for 5 minutes and the endpoint degrades silently to the old local-only list when unset.
+- fix: the SSO group lookup authenticates with `Authorization: Bearer <token>`, not the `auth-token` header — the latter is for browser session UUIDs and would be rejected for a minted API token.
+- docs: `docs/concepts-hosts.md` gains a "Putting a host behind single sign-on" section covering the per-host `/__proxy_auth` flow, the wildcard redirect URI the IdP must allow, and where group suggestions come from.
+- docs: `secrets.js.example` documents the new `sso` block.
+
+## v1.33.0
+- feat: Add SSO-style error page (404/500) for browser navigation instead of a bare JSON/text response
+- feat: DNS page is now admin-only (hidden from non-admins; API already admin-gated)
+- feat: navbar — username no longer underlined; only the active link is bold + underlined

+# Deployment Guide — theta42/proxy
+
+The proxy is an OpenID Connect-protected reverse proxy (OpenResty front + Node
+management app + Redis) that is **both** an OIDC client of an SSO Manager *and*
+a direct LDAP client for user lookups. Two deployment methods:
+
+1. **Docker** — a single all-in-one image bundling OpenResty + the app + Redis
+   (`docker compose up`).
+2. **Bare metal** — `ops/install.sh` on Debian/Ubuntu (installs Node.js,
+   OpenResty, Lua modules, Redis, and a systemd unit).
+
+## How configuration works
+
+The app loads configuration via [`@simpleworkjs/conf`](https://www.npmjs.com/package/@simpleworkjs/conf),
+which deep-merges, in order:
+
+1. `conf/base.js` (committed, generic defaults)
+2. `conf/<NODE_ENV>.js` (optional)
+3. `conf/secrets.js` (gitignored — secrets + per-deployment values)
+4. **`app_*` environment variables** — the highest-precedence layer
+
+Any env var whose name starts with `app_` overrides the merged config. The rest
+of the name is split on **double-underscore** (`__`) into a nested path. Values
+are `JSON.parse`-coerced when possible and kept as raw strings otherwise.
+
+| Env var | Sets | Notes |
+|---------|------|-------|
+| `app_oidc__issuer` | `conf.oidc.issuer` | browser-facing SSO URL |
+| `app_oidc__authorizationEndpoint` | `conf.oidc.authorizationEndpoint` | browser-facing |
+| `app_oidc__tokenEndpoint` | `conf.oidc.tokenEndpoint` | server-to-server; can be internal |
+| `app_oidc__userinfoEndpoint` | `conf.oidc.userinfoEndpoint` | server-to-server; can be internal |
+| `app_oidc__endSessionEndpoint` | `conf.oidc.endSessionEndpoint` | browser-facing |
+| `app_oidc__clientId` / `app_oidc__clientSecret` | OIDC client creds | register in the SSO first |
+| `app_oidc__redirectUri` | `conf.oidc.redirectUri` | must match the SSO client exactly |
+| `app_oidc__enabled` | `conf.oidc.enabled` | boolean |
+| `app_ldap__url` | `conf.ldap.url` | `ldaps://…:636` or `ldap://…:389` |
+| `app_ldap__bindDN` / `app_ldap__bindPassword` | LDAP service account | don't reuse the admin DN |
+| `app_ldap__searchBase` / `app_ldap__userFilter` | user search | |
+| `app_ldap__tlsOptions__rejectUnauthorized` | `conf.ldap.tlsOptions.rejectUnauthorized` | `false` for self-signed LDAPS |
+| `app_ldap__tlsOptions__ca` | `conf.ldap.tlsOptions.ca` | path to a CA cert for strict trust |
+| `app_auth__adminUsers` | `conf.auth.adminUsers` | local anti-lockout admin (uid) |
+| `app_auth__adminGroups` | `conf.auth.adminGroups` | SSO/LDAP groups that are global admin (JSON array) |
+| `app_auth__localAdminPass` | `conf.auth.localAdminPass` | initial password for the local anti-lockout admin (used once, on first creation only — defaults to the username itself if unset) |
+| `app_redis__prefix` | `conf.redis.prefix` | default `proxy_` |
+
+See [`docs/docker.md`](docs/docker.md) for a shorter, container-focused version
+of this reference.
+
+> **Requires `@simpleworkjs/conf` >= 1.1.0.** The Docker image will not honor
+> `app_*` env vars on 1.0.0. The lock is already on `^1.1.0`; if you regenerate it:
+> ```bash
+> cd nodejs && npm install @simpleworkjs/conf@^1.1.0
+> ```
+
+---
+
+## Method 1: Docker (all-in-one)
+
+The image (`Dockerfile`) bundles OpenResty + the app + Redis in one container,
+mirroring the bare-metal `ops/install.sh` layout. `docker-entrypoint.sh`:
+generates the fallback SSL cert, parameterizes the OpenResty `resolver`/
+`set_real_ip_from` directives, starts Redis + the node app, and execs OpenResty
+in the foreground under `dumb-init`.
+
+### Setup
+
+The bundled `docker-compose.yml` reads the OIDC + LDAP + auth wiring from a
+bind-mounted `./config/proxy-secrets.js` (not from `app_*` env). Copy the
+example, fill in your secrets, then build + start:
+
+```bash
+mkdir -p config && chmod 700 config
+cp secrets.js.example config/proxy-secrets.js
+$EDITOR config/proxy-secrets.js     # set oidc.clientId/clientSecret, ldap.bindPassword, ...
+docker compose up -d --build
+```
+
+`docker-entrypoint.sh` sets `CONF_SECRETS=/config/proxy-secrets.js` so
+`@simpleworkjs/conf` reads it directly. No `app_*` env is passed — `app_*` env
+would override the file (env beats secrets.js in `@simpleworkjs/conf`), so the
+file is kept authoritative. `RESOLVER` / `REAL_IP_FROM` / `NODE_ENV` /
+`NODE_PORT` are OpenResty-runtime / process env, not `app_*` config, so they
+stay in the compose.
+
+> Running the unified `theta-env` stack? Its `setup.sh` generates
+> `./config/proxy-secrets.js` (+ `./config/sso-secrets.js`) for you and
+> registers the OAuth client with the SSO — see the theta-env README.
+
+### Access
+
+- Proxy (public): `https://<host>/` — OpenResty front, auto-SSL (Let's Encrypt)
+- Management UI / API: `http://127.0.0.1:3000/` (bound to localhost; the front
+  proxies the UI under its own TLS)
+- Health: `http://127.0.0.1:3000/health` → `{"status":"ok"}`
+
+### API tokens (personal access tokens)
+
+Any logged-in user can mint a long-lived bearer token to call the management
+API from scripts/CI/other services, without an OIDC browser session. Tokens are
+self-service and authenticate **as their creator**: the creator's groups are
+snapshotted at mint time (mirroring how the proxy's browser session captures
+groups at login — the proxy never re-queries the IdP), and the existing authz
+layer (`Permission.effectiveFor` / `roles.resolveEffective`) applies unchanged.
+Local groups and owned-domain rights are recomputed live each request; only the
+SSO/LDAP group membership is the mint-time snapshot.
+
+Create one in the UI under **API Tokens** (the token string is shown **once**),
+then use it as a bearer token:
+
+```bash
+curl -H "Authorization: Bearer prx_<id>_<secret>" https://proxy.example.com/api/host
+```
+
+Format: `prx_<id>_<secret>` — the `id` is the lookup key, the `secret` is
+bcrypt-hashed and never stored in plaintext. Rotate or revoke from the same page
+(immediate effect). Optional expiry (in days) at creation. Tokens persist in the
+bundled Redis (AOF — see *Backups and restore*), so they survive rebuilds.
+
+The token carries the creator's effective rights: a global admin's token can
+manage Hosts/Users/Groups; a domain manager's token can manage their own
+domains but `requireAdmin` routes return 403. To tighten permissions after group
+changes, revoke and re-mint the token.
+
+### OpenResty runtime env
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `RESOLVER` | `127.0.0.11` | DNS for upstream names in Host records (Docker's embedded DNS) |
+| `REAL_IP_FROM` | _empty_ | Trusted CIDR for `X-Real-IP`. Empty = proxy is the front (removes the real_ip block). Set to an upstream proxy's CIDR if one sits in front. |
+
+### Auto-SSL / Let's Encrypt
+
+`lua-resty-auto-ssl` stores certs in the bundled Redis. Redis is now AOF+RDB
+persisted to the `proxy-data` volume (not in-memory), so **Let's Encrypt certs
+survive container recreation** — no re-issue / rate-limit on rebuild. Port 80 is
+required for HTTP-01 challenges (mapped in the compose).
+
+### Backups and restore
+
+**What lives where**
+
+| State | Location | Persisted? |
+|-------|----------|------------|
+| Host records, permissions, DNS creds, local users | `proxy-data` volume (`/data`, Redis) | yes (AOF + RDB) |
+| Let's Encrypt certs (auto-ssl) | `proxy-data` volume (`/data`, Redis) | yes — same Redis |
+| nginx response cache / logs | `proxy-cache` / `proxy-logs` volumes | yes (volume) |
+| Secrets (OIDC client secret, LDAP bind password) | `./config/proxy-secrets.js` (bind mount) | your responsibility — back up off-host |
+
+**Automatic snapshots** — when run as part of the unified `theta-env` stack,
+`setup.sh` snapshots Redis + `./config/` to `./backups/<timestamp>/` before every
+rebuild and keeps the last `BACKUP_KEEP` (default 5). Standalone deployments
+should run `ops/backup.sh` the same way (on a cron/systemd timer, or by hand
+before an upgrade):
+
+```bash
+./ops/backup.sh              # keeps the last 5 by default
+./ops/backup.sh 10           # or override retention
+BACKUP_KEEP=10 ./ops/backup.sh
+```
+
+It snapshots Redis (`BGSAVE`, falling back to a synchronous `SAVE` if that
+doesn't complete quickly) and `./config/` to `./backups/<timestamp>/`,
+pruning older backups beyond the retention count — the same approach
+`theta-env`'s `setup.sh` uses, just scoped to this one container. Equivalent
+manual steps, if you'd rather not use the script:
+
+```bash
+# Redis — hot snapshot: trigger a save, then copy the RDB out
+docker compose exec proxy redis-cli BGSAVE
+docker compose cp proxy:/data/dump.rdb proxy-redis-$(date +%F).rdb
+
+# Secrets — copy the config dir (holds OIDC client secret, LDAP bind password)
+cp -a ./config config-backup-$(date +%F) && chmod 700 config-backup-$(date +%F)
+```
+Store the backup **off the host** — it contains secrets and the whole
+Host/permission/user dataset.
+
+**Restore — Redis (full proxy state + certs)**
+
+```bash
+cp -a config-backup-<date> ./config && chmod 700 ./config
+docker compose up -d
+docker compose stop proxy
+# AOF wins on startup — delete it so the RDB is loaded instead (see note).
+docker compose run --rm --no-deps --entrypoint sh proxy -c \
+  'rm -f /data/appendonly.aof /data/appendonly.aof.*'
+docker compose cp proxy-redis-<date>.rdb proxy:/data/dump.rdb
+docker compose start proxy
+```
+
+> **AOF vs RDB (important):** with `--appendonly yes`, Redis loads
+> `appendonly.aof` on startup and **ignores** `dump.rdb` if the AOF exists. To
+> restore from an RDB snapshot you **must delete the AOF first** (the runbook
+> does this); Redis then loads the RDB and writes a fresh AOF. Verify:
+> `docker compose exec proxy redis-cli DBSIZE`.
+>
+> Restoring Redis restores cert state **at the snapshot time** — certs issued
+> after the snapshot are lost and will be re-issued on next request.
+
+**Upgrades**
+
+```bash
+./setup.sh          # backs up, then rebuilds — proxy-data keeps Redis state
+# (standalone) docker compose pull && docker compose up -d
+```
+Host records, permissions, DNS creds, local users, and Let's Encrypt certs all
+survive the rebuild because they live on the `proxy-data` volume, not in the
+image. **Migrations note:** if a release ships a `nodejs/migrations/` script,
+run it after upgrading (it transforms in-Redis records); see the release notes.
+
+### Logs
+
+OpenResty runs in the foreground and the Node app in the background, both
+writing to the container's stdout/stderr. nginx access/error logs go to files
+(`/var/log/nginx`, on the `proxy-logs` volume), so they do **not** appear in
+`docker logs`.
+
+```bash
+docker compose logs -f proxy                       # app + OpenResty (stdout/stderr)
+docker compose exec proxy tail -f /var/log/nginx/error.log   # nginx errors
+docker compose exec proxy tail -f /var/log/nginx/access.log  # nginx access
+docker compose logs --tail=200 --since=10m proxy    # recent context
+```
+
+---
+
+## Method 2: Bare metal (Debian/Ubuntu)
+
+`ops/install.sh` is an idempotent installer: it installs Node.js 22.x, OpenResty
+(from openresty.org), Lua modules (luarocks), Redis, force-syncs the repo to
+`/opt/theta42/proxy`, symlinks the OpenResty + systemd config from the repo, and
+starts `proxy.service`. Re-run it to update — it prints the version you're
+updating from and to (or "Already up to date" if there's nothing new).
+
+```bash
+wget -O - https://raw.githubusercontent.com/theta42/proxy/master/ops/install.sh | sudo bash
+```
+
+or, if you already have the repo checked out:
+
+```bash
+sudo ./ops/install.sh
+```
+
+Configuration is file-based: on first run the installer seeds
+`/etc/proxy/secrets.js` from `secrets.js.example` (placeholders you must fill
+in — OIDC + LDAP values, see `nodejs/conf/base.js` for the shape). Edit it,
+then `sudo systemctl restart proxy`. Later runs never touch an existing
+secrets file.
+
+---
+
+## Fronting an SSO Manager
+
+The proxy is a natural front for [`theta42/sso-manager-node`](https://github.com/theta42/sso-manager-node):
+it terminates TLS for the SSO's UI and protects it with OIDC login, while also
+binding to the SSO's LDAP directly for user lookups. To run both together:
+
+1. **One Docker network** so the proxy can reach the SSO internally at
+   `http://sso-manager:3001` (token/userinfo, server-to-server) and
+   `ldaps://sso-manager:636` (LDAP).
+2. **Set the SSO's `OAUTH_ISSUER`** to the browser-facing HTTPS URL the proxy
+   serves the SSO at (e.g. `https://sso.example.com`).
+3. **Register the proxy as an OIDC client** in the SSO, with a `redirectUri`
+   matching the proxy's callback (`https://proxy.example.com/api/auth/oidc/callback`).
+4. **LDAP**: point `app_ldap__url` at `ldaps://sso-manager:636` and create a
+   dedicated service account (`cn=ldapclient,ou=people,…`) — don't reuse the
+   admin DN. For the SSO's self-signed LDAPS cert, set
+   `app_ldap__tlsOptions__rejectUnauthorized=false` (or mount the cert and use
+   `app_ldap__tlsOptions__ca=<path>`).
+
+The [`theta42/theta-env`](https://github.com/theta42/theta-env) unified repo
+automates all four steps with `./setup.sh`.
+
+---
+
+## Security notes
+
+1. **Never commit `secrets.js`** — it's in `.gitignore`.
+2. **Bind the management port to localhost** (the compose does: `127.0.0.1:3000`).
+   The OpenResty front proxies the UI under TLS; don't expose 3000 to the LAN.
+3. **`REAL_IP_FROM` empty by default** — the proxy trusts no one to set `X-Real-IP`
+   (it's the front). Only set it if a trusted proxy sits in front.
+4. **LDAPS for any LDAP that crosses the network.** Use `ldaps://`/StartTLS; plain
+   `ldap://` is fine only on a private docker network.
+5. The image runs OpenResty workers as `nobody` and the node app as root (matches
+   the bare-metal systemd unit). Harden to a non-root user for production if needed.

+description: The proxy's management REST API — hosts, DNS providers, users, groups, and permissions.
+---
+
+# API Documentation
+
+[← Back to Home](index.html)
+
+All API endpoints require authentication unless otherwise noted. Three
+authentication methods are supported:
+
+- **`auth-token` header** — a browser-session token from `POST /api/auth/login`
+  or the OIDC flow (below).
+- **`Authorization: Bearer <token>` header** — a self-service API token (PAT,
+  see [API Tokens](#api-tokens)), for scripts/CI without a browser session.
+- **OIDC (browser)** — if the proxy is configured as an OIDC client of an SSO
+  (`app_oidc__*` / `conf.oidc`, see [DEPLOYMENT.md](https://github.com/theta42/proxy/blob/master/DEPLOYMENT.md)),
+  users can log in via `GET /api/auth/oidc/start` instead of posting a
+  username/password.
+
+The proxy can also be configured as a **direct LDAP client** (`app_ldap__*` /
+`conf.ldap`) for looking up/validating users, independent of the OIDC flow —
+see DEPLOYMENT.md for the full configuration reference.
+
+Authenticated requests also carry **RBAC** (role-based access control):
+global admins can manage everything; other users are scoped to `viewer` or
+`manager` rights on specific domains via [Permissions](#permissions) and
+[Groups](#groups).
+
+Base URL: `https://your-proxy-host.com/api`

+
+`subdomains` is a comma-separated list of the subdomains you've registered at

+DuckDNS only supports one A/AAAA record and one TXT record per domain (no
+arbitrary sub-records) — enough for dynamic DNS and DNS-01 wildcard certs.

+
+```bash
+curl -H "auth-token: your-token-here" \
+  https://proxy-host.com/api/dns/dynamic/ip
+```
+
+**Responses:**
+- `200` `{"ip": "203.0.113.5"}`
+
+#### List Dynamic Records
+
+**GET** `/api/dns/dynamic`

+**DELETE** `/api/dns/dynamic/:id`
+
+Stop managing a record. Requires `manager` rights on the record's domain.
+Leaves the provider's A record in place at its last value.
+
+```bash
+curl -H "auth-token: your-token-here" \
+  -X DELETE \
+  https://proxy-host.com/api/dns/dynamic/<id>

+## Certificates
+
+Retrieve SSL certificate information.
+
+### Get Certificate
+
+**GET** `/api/cert/:host`
+
+Get the SSL certificate for a host.

+- `500` Internal server error
+
+## Notes
+
+- All timestamps are in milliseconds since epoch
+- Authenticated endpoints accept either the `auth-token` header (browser
+  session / OIDC login) or an `Authorization: Bearer <token>` API token
+- Host names support wildcards: `*` (single level) and `**` (multi-level)
+- DNS providers are validated on creation - invalid API credentials will be rejected

+```
+
+### Redis (Data Store)
+
+**ORM:** [model-redis](https://www.npmjs.com/package/model-redis) - A lightweight Redis ORM for Node.js with schema validation, relationships, and automatic key management.
+
+**Stored Data:**
+- Host configurations (domain, IP, port, SSL settings)
+- User accounts and hashed passwords
+- Authentication tokens
+- SSL certificates (for wildcard domains)
+- DNS provider credentials
+- Domain-to-provider mappings
+
+**Key Prefixes:**
+```
+proxy_Host_<hostname>           # Host configuration
+proxy_User_<username>           # User account
+proxy_AuthToken_<token>         # Auth tokens
+proxy_DnsProvider_<id>          # DNS provider
+proxy_Domain_<domain>           # Domain info
+<hostname>:latest               # SSL certificate cache
+```
+
+## Request Flow
+
+### Standard HTTP/HTTPS Request
+
+1. **Client** sends HTTPS request to `app.example.com`
+2. **OpenResty** receives request, terminates SSL
+3. **Lua script** (`targetinfo.lua`) queries **Redis first** for host config
+4. If **found in Redis**, jump to step 7 (Node.js not involved)
+5. If **not in Redis**, Lua queries Node.js via Unix socket as fallback
+6. **Node.js** performs host lookup (supports wildcards), caches result in Redis
+7. **OpenResty** proxies request to backend service using target IP and port
+8. **Response** proxied back to client
+
+**Resilience**: If Node.js goes down, all hosts already cached in Redis continue to work. Only new/uncached hosts will fail until Node.js recovers.
+
+### Wildcard SSL Certificate Request
+
+1. **User** creates wildcard host (`*.example.com`) via API
+2. **Node.js** validates domain has DNS provider configured
+3. **Let's Encrypt** DNS-01 challenge initiated
+4. **DNS provider** API creates TXT record (`_acme-challenge.example.com`)
+5. **Let's Encrypt** validates TXT record
+6. **Certificate** generated and stored in Redis
+7. **DNS provider** cleans up TXT record
+8. **Background scheduler** monitors expiration, renews 30 days before expiry
+
+## Host Lookup Algorithm
+
+The lookup tree enables sophisticated domain matching:
+
+```
+Input: "api.v1.example.com"
+
+Tree Structure:
+{
+  "com": {
+    "example": {
+      "*": {          // Matches api.example.com
+        "#record": {...}
+      },
+      "v1": {
+        "api": {      // Matches api.v1.example.com (exact)
+          "#record": {...}
+        }
+      }
+    }
+  }
+}
+
+Priority: Exact > Single wildcard (*) > Double wildcard (**)
+```
+
+**Wildcard Types:**
+- `example.com` - Exact match only
+- `*.example.com` - Matches `sub.example.com` (single level)
+- `**.example.com` - Matches any depth (`sub.deep.example.com`)
+- `api.*.example.com` - Matches `api.v1.example.com`, `api.v2.example.com`
+
+## Security Architecture
+
+### Authentication Flow
+
+1. User sends credentials to `/api/auth/login`
+2. Credentials validated against stored hash (bcrypt)
+3. Token generated and stored in Redis with TTL
+4. Token returned to client
+5. Subsequent requests include token in `auth-token` header
+6. Middleware validates token before processing request
+
+### SSL Certificate Security
+
+- **Private keys** stored only in Redis (memory/disk based on config)
+- **Fallback certificates** used when SNI unavailable
+- **Let's Encrypt** rate limiting respected
+- **DNS provider credentials** marked as `isPrivate` (not returned in API)
+
+### Unix Socket Communication
+
+- Socket file: `/var/run/proxy_lookup.socket`
+- Permissions: `777` (container-safe, single-use deployment)
+- Protocol: JSON over Unix stream socket
+- Buffer handling: Accumulates partial messages until complete JSON
+
+## Performance Optimizations
+
+### Caching Strategy
+
+The system uses a multi-tier caching approach:
+
+1. **Redis (L1 Cache)** - OpenResty checks Redis FIRST for every request
+   - Primary host configuration storage
+   - Survives Node.js restarts/failures
+   - Shared across all OpenResty workers
+
+2. **Node.js Lookup Tree (L2 Cache)** - In-memory host lookup with wildcard matching
+   - Only queried when Redis has no entry
+   - Rebuilt automatically when hosts change
+   - Supports complex wildcard resolution
+
+3. **Wildcard Parent Caching** - Resolved wildcard matches stored back to Redis
+   - Subsequent requests to `api.example.com` hit Redis directly
+   - No repeated wildcard resolution needed
+
+### Unix Socket vs HTTP API
+
+Unix socket chosen over HTTP for host lookups:
+- **Lower latency** - No TCP overhead
+- **Higher throughput** - No HTTP parsing
+- **Simpler** - Direct JSON communication
+- **Secure** - Filesystem permissions, no network exposure
+
+## Scalability Considerations
+
+### Current Architecture
+
+- **Single instance** - OpenResty + Node.js + Redis on one server
+- **Vertical scaling** - Add CPU/RAM as needed
+- **Limitations** - Unix socket ties OpenResty to Node.js on same host
+
+### Future Scaling Options
+
+- **Redis cluster** - Distribute data storage
+- **Multiple OpenResty instances** - Load balance incoming requests
+- **Stateless Node.js** - Run multiple API instances
+- **Replace Unix socket** - Use TCP/HTTP for cross-host communication
+- **Separate cert management** - Dedicated service for wildcard SSL
+
+## Monitoring and Observability
+
+### Logs
+
+- **OpenResty**: `/var/log/nginx/access.log`, `/var/log/nginx/error.log`
+- **Node.js**: `journalctl -u proxy.service`
+- **Redis**: `redis-cli MONITOR`
+
+### Health Checks
+
+- Node.js API: `curl http://localhost:3000/api/host`
+- Redis: `redis-cli PING`
+- OpenResty: `systemctl status openresty`
+- Unix socket: `ls -la /var/run/proxy_lookup.socket`
+
+### Metrics to Monitor
+
+- Request rate and response times
+- SSL certificate expiration dates
+- Redis memory usage
+- Host lookup cache hit rate
+- Background service execution times

+
+# Users, Groups & Permissions
+
+This page explains, in plain language, who can manage what in this app. For
+the deeper system-design detail, see [Architecture](architecture.html).
+
+## Two different ways to log in
+
+Most people who use apps you've proxied through this app never see this
+app's own login at all — they use whatever authentication you set up on
+the *individual host* (basic auth, or single sign-on through your SSO
+Manager). This page is about a different, smaller group: the people who
+manage the proxy itself — adding hosts, registering DNS providers, and so
+on.
+
+There are two ways someone gets into the proxy's own management UI:
+
+- **A local account**, created on the **Users** page — a username and
+  password specific to this app.
+- **Single sign-on**, if you've connected this proxy to an SSO Manager (or
+  another OIDC provider) — the same login your other connected apps use.
+
+Either way, once logged in, what they're actually *allowed to do* here is
+controlled by permissions, described below.
+
+## Groups
+
+A **group** here is just a named list of local usernames, used to grant
+the same permission to several people at once instead of one at a time.
+If you're using SSO instead of local accounts, group membership normally
+comes from your identity provider instead — local groups exist mainly for
+the local-account case.
+
+## Permissions: scope + role
+
+Each **permission** entry grants one subject (a user or a group) one
+**role**, at one **scope** — the two are independent choices:
+
+**Scope** — *where* the role applies:
+
+- **Domain** — only hosts under one specific domain (e.g. someone can
+  manage everything under `example.com`, but can't see or touch a
+  completely different domain you also proxy).
+- **Global** — everywhere, across every domain this proxy manages.
+
+**Role** — *what* they can do within that scope:
+
+- **Viewer** — read-only. Can see hosts and their settings, but not
+  change anything.
+- **Manager** — full control over hosts (create, edit, delete) within
+  that scope.
+- **Admin** — same host control as Manager, **plus**, but *only when
+  granted at Global scope*, the ability to manage other people's
+  permissions, DNS providers, and local user accounts. An Admin role
+  granted at Domain scope instead of Global behaves exactly like Manager
+  for that one domain — it does not unlock those extra admin-only pages.
+
+In practice: give someone **Manager** on just the domain(s) they're
+responsible for to delegate day-to-day host management without handing
+them the keys to everything. Reserve **Global Admin** for people who
+should be able to change anything, anywhere, including who else has
+access.

+title: API Tokens
+description: A plain-language guide to personal access tokens in theta42/proxy.
+---
+
+# API Tokens
+
+This page explains what an API token is and when you'd want one. For the
+full list of API endpoints a token can call, see the
+[API reference](api.html).
+
+## What's an API token, in plain terms?
+
+Normally, you interact with this app by logging in through a web browser.
+An **API token** (also called a personal access token, or PAT) is an
+alternative way in — a long, random string that a script, a scheduled job,
+or another program can use instead of a username and password, to act on
+your behalf without a human typing a login in each time.
+
+If you've ever set up a script to talk to GitHub, GitLab, or a similar
+service using a "token" instead of your real password, this is the same
+idea.
+
+## When would you actually need one?
+
+Most people never need to create one of these — you'll only want a token
+if you're automating something, for example:
+
+- A script that registers or updates hosts automatically (say, spinning up
+  a new service and wanting the proxy entry created for it without a
+  manual step).
+- A monitoring or backup job that checks this app's health via its API.
+- A configuration-management tool that keeps your host list in sync with
+  something else.
+
+If you're not doing any of that, you don't need an API token — just log in
+normally through the web UI.
+
+## How it works
+
+Create a token from your Profile page, give it a name so you remember what
+it's for later, and optionally an expiry. You'll be shown the token's
+value **exactly once** — copy it somewhere safe immediately, because it
+can't be viewed again afterward (only revoked or rotated). Whatever script
+or tool you're using it with sends it along with each request, the same
+way a browser sends your login session.
+
+A token acts **as you**, with **your** [permissions](concepts-access.html)
+— if you're only a Manager on one domain, a token you create can't touch
+any other domain either. If you ever suspect a token has leaked (ended up
+somewhere it shouldn't have, like a public script or log file), revoke it
+immediately from your Profile page; it stops working right away.
+
+## Want more detail?
+
+This page doesn't attempt to list every API endpoint or show request/
+response examples — for that, see the full [API reference](api.html).

+title: DNS Providers
+description: A plain-language guide to why theta42/proxy needs a DNS provider, and only for wildcard certificates.
+---
+
+# DNS Providers
+
+This page explains, in plain language, what a "DNS provider" is for in this
+app and when you actually need one. For setup steps, see
+[Installation](installation.html).
+
+## Do you need this at all?
+
+**Only if you want a [wildcard host](concepts-hosts.html)** (something like
+`*.example.com` covering every subdomain with one certificate). A normal,
+single-name host doesn't need a DNS provider configured at all — skip this
+page entirely if that's all you're setting up.
+
+## Why a wildcard cert needs this extra step
+
+To prove you actually own `example.com` before issuing a certificate that
+covers *every* possible subdomain of it, Let's Encrypt needs to see a
+specific, temporary DNS record appear on that domain — something only the
+real owner of the domain could add. A normal single-host certificate
+doesn't need this because it can prove ownership a simpler way (by
+responding to a web request instead).
+
+So: to get a wildcard certificate, this app needs to be able to add (and
+later remove) that one temporary DNS record on your domain automatically,
+which means it needs your domain registrar or DNS host's API credentials —
+that's what registering a **DNS provider** here does.
+
+## What you're actually giving it access to
+
+A DNS provider entry only needs enough access to add/remove TXT records —
+it's not given your registrar account's full login, and it can't do
+anything to your domain besides that one narrow task (and, for some
+providers, keeping a dynamic A record updated if you use that feature
+separately). Check your specific provider's page in the
+[Installation guide](installation.html) for exactly what kind of
+credential to generate and how narrowly you can scope it.
+
+## Want more detail?

+DuckDNS, etc.), see [Installation](installation.html).

+
+# Hosts & HTTPS
+
+This page explains, in plain language, what a "host" is and how this app
+gets you working HTTPS without you having to think about certificates. For
+the deeper system-design detail, see [Architecture](architecture.html); for
+step-by-step setup, see [Installation](installation.html).
+
+## What's a "host"?
+
+A **host** is one entry telling the proxy: "when someone requests *this*
+public address, send them to *that* server." For example: requests for
+`photos.example.com` get sent to the little box in your closet running your
+photo app on port 8080. Each app or service you want to reach from outside
+your network — a home automation dashboard, a media server, this proxy's
+own management UI — gets its own host entry.
+
+Two settings on a host are easy to mix up:
+
+- **Incoming host name** — the public address people type in their
+  browser (`photos.example.com`).
+- **Target IP/port** — where the proxy actually sends the request behind
+  the scenes (`10.0.0.5:8080`, or a hostname like `photo-server`).
+
+Everything else on the host form (traffic limits, access rules,
+authentication) is optional — a bare host with just those two fields
+already works.
+
+## HTTPS certificates: mostly automatic
+
+Every public website needs an HTTPS certificate so browsers show the lock
+icon instead of a scary warning. This app gets one for you automatically
+from [Let's Encrypt](https://letsencrypt.org) the first time a host is
+actually requested — you don't manually request, install, or renew
+anything for a normal host. This happens behind the scenes using a method
+called **HTTP-01**, and it's the default for every new host.
+
+## Wildcards: one certificate for a whole family of hosts
+
+Sometimes you want *every* subdomain under one name to work — `app1.`,
+`app2.`, `anything.example.com` — without registering each one by hand and
+waiting for its own certificate. That's what a **wildcard** host does: a
+single host entry named `*.example.com` gets one certificate that covers
+the whole family at once. Setting one up needs one extra piece of
+information the automatic method above doesn't need — see
+[DNS Providers](concepts-dns.html) for why.
+
+Once a wildcard exists, you have two ways to actually use it:
+
+- **Register nothing else, and turn on "Match any subdomain"** on the
+  wildcard host itself — *any* subdomain that doesn't already have its own
+  entry gets automatically routed to the wildcard's target the first time
+  it's requested. Convenient, but it means literal typos and random scan
+  traffic get routed too, not just the subdomains you meant to use.
+- **Register each subdomain as its own host, as a "Parent Wildcard"
+  child** — more setup, but each subdomain can point at a different
+  target/server while still reusing the one wildcard certificate instead
+  of getting its own. This is the recommended default and is what
+  "Match only subdomains defined here" (the host form's default) does.
+
+You'll see the **"Parent Wildcard"** option light up automatically on the
+host form whenever the name you're entering already has a matching
+wildcard available to reuse — including the wildcard's own bare base
+domain (e.g. `example.com` itself, not just `something.example.com`).
+
+## Putting a host behind single sign-on
+
+Each host can be gated on its own, independently of the proxy's management UI.
+On the host's **Auth** tab pick **Single sign-on (SSO)** and, optionally, fill in
+the **Allowed users** / **Allowed groups** lists. Empty lists mean any
+authenticated user is allowed; otherwise the identity must match one of them.
+
+The proxy runs the OIDC flow itself at `/__proxy_auth` on the protected host and
+keeps a Redis-backed session in a `__proxy_sso` cookie, so the app behind it
+needs no changes.
+
+**The IdP must allow the per-host callback.** Each protected host calls back to
+`https://<that-host>/__proxy_auth/callback`, which is a different URL for every
+host, all against the proxy's one OAuth client. Register a wildcard redirect URI
+on that client — the SSO Manager supports `*` (one label) and `**` (any number):
+
+```
+https://**.example.com/__proxy_auth/callback
+https://example.com/__proxy_auth/callback
+```
+
+theta-suite's bootstrap registers both automatically, and backfills them onto an
+existing client. Without them, switching a host to SSO fails at the IdP with
+`400 redirect_uri is not registered for this client`.
+
+**Group suggestions come from the SSO.** The Allowed groups field autocompletes
+from the SSO directory's groups when `sso.url` and `sso.apiToken` are set in the
+proxy's config (theta-suite's bootstrap mints that read-only token). Without it
+the field can only suggest the proxy's local groups, which for an SSO-gated host
+are rarely the ones you want — the allow-list is matched against the `groups`
+claim in the SSO's token, so only SSO groups can ever match.
+
+## Load Balancing
+
+If you have multiple servers running the same application, you can load balance traffic across them. When editing a host, you can specify **Additional Targets** (one `IP:port` per line). The proxy will automatically distribute incoming requests across your primary target and all additional targets using a round-robin strategy, providing simple high availability and load distribution without extra configuration.
+
+## Want more detail?

+This page skips the system-internals (Redis, OpenResty, the lookup service)
+and the exact install steps. For those, see
+[Architecture](architecture.html) and [Installation](installation.html).

+# Contributing Guide
+
+[← Back to Home](index.html)
+
+Thank you for considering contributing to the Proxy project! This guide will help you get started.
+
+## Development Setup
+
+### Prerequisites
+
+- Node.js 18+ (18.x, 20.x, or 22.x recommended)
+- Redis server
+- Git
+
+### Local Development
+
+1. **Clone the repository**
+   ```bash
+   git clone https://github.com/theta42/proxy.git
+   cd proxy/nodejs
+   ```
+
+2. **Install dependencies**
+   ```bash
+   npm install
+   ```
+
+3. **Start Redis** (if not already running)
+   ```bash
+   redis-server
+   ```
+
+4. **Run in development mode**
+   ```bash
+   npm run dev
+   ```
+
+   This starts the Node.js API with nodemon for auto-reload on file changes.
+
+5. **Access the API**
+   - API: `http://localhost:3000/api`
+   - Web UI: `http://localhost:3000`
+
+## Testing
+
+The project uses Node.js built-in test runner (requires Node 18+).
+
+### Running Tests
+
+```bash
+# Run all tests
+npm test
+
+# Run only unit tests
+npm run test:unit
+
+# Run only integration tests
+npm run test:integration
+
+# Watch mode for development
+npm run test:watch
+```
+
+### Test Structure

+```
+
+### Writing Tests
+
+We test **custom logic**, not third-party libraries:
+
+**DO test:**
+- Host lookup algorithm
+- Socket buffering logic
+- DNS provider contracts
+- Custom utility functions
+
+**DON'T test:**
+- Express.js routing
+- Redis ORM
+- External DNS APIs (use mocks instead)
+
+### Adding DNS Provider Tests
+
+When adding a new DNS provider, you **must** add contract tests:
+
+```javascript
+describe('NewProvider Provider', () => {
+    const NewProvider = require('../../models/dns_provider/newprovider');
+
+    test('should meet DNS provider contract', () => {
+        const mockCredentials = {api_key: 'mock-key'};
+        const instance = validateDnsProviderContract(NewProvider, mockCredentials);
+        assert.ok(instance);
+    });
+
+    test('should have valid method signatures', () => {
+        const instance = new NewProvider({api_key: 'mock'});
+        validateMethodSignatures(instance);
+    });
+
+    test('should validate key mapping', () => {
+        const instance = new NewProvider({api_key: 'mock'});
+        validateKeyMapping(instance);
+    });
+
+    test('should validate type checking', () => {
+        const instance = new NewProvider({api_key: 'mock'});
+        validateTypeChecking(instance);
+    });
+});
+```
+
+See `test/integration/dns_provider.test.js` for examples.
+
+## Code Style
+
+### General Guidelines
+
+- Use strict mode: `'use strict';`
+- Use tabs for indentation
+- Clear, descriptive variable names
+- Comment complex logic
+- No trailing whitespace
+
+### File Organization
+
+```javascript
+'use strict';
+
+// 1. Node.js built-ins
+const fs = require('fs');
+const path = require('path');
+
+// 2. Third-party modules
+const express = require('express');
+const redis = require('redis');
+
+// 3. Local modules
+const {Host} = require('./models');
+const middleware = require('./middleware/auth');
+
+// 4. Code...
+```
+
+### Naming Conventions
+
+- Classes: `PascalCase`
+- Functions: `camelCase`
+- Constants: `UPPER_SNAKE_CASE`
+- Private methods: `__privateMethod` (double underscore prefix)

+
+**Example Model:**
+```javascript
+const Table = require('../utils/redis_model');
+
+class Host extends Table {
+    static _key = 'host';  // Primary key field
+    static _keyMap = {
+        'host': {isRequired: true, type: 'string', min: 3, max: 500},
+        'ip': {isRequired: true, type: 'string', min: 3, max: 500},
+        'targetPort': {isRequired: true, type: 'number', min: 0, max: 65535},
+        'forcessl': {default: true, type: 'boolean'},
+        'created_on': {default: () => Date.now(), type: 'number'}
+    };
+}
+```

+description: Running the proxy's all-in-one Docker image — OpenResty, the management app, and Redis in one container.
+---
+
+# Docker Deployment
+
+[← Back to Home](index.html)
+
+The proxy ships as a single all-in-one Docker image bundling **OpenResty + the
+Node management app + Redis** in one container, mirroring the bare-metal
+[`ops/install.sh`](https://github.com/theta42/proxy/blob/master/ops/install.sh)
+layout. This is the easiest way to run the proxy standalone, or as part of the
+unified [theta-env](https://github.com/theta42/theta-env) stack.
+
+## Quick start (standalone)
+
+```bash
+git clone https://github.com/theta42/proxy.git
+cd proxy
+mkdir -p config && chmod 700 config
+cp secrets.js.example config/proxy-secrets.js   # set OIDC/LDAP wiring
+$EDITOR config/proxy-secrets.js
+docker compose up -d --build
+```
+
+- Proxy (public, auto-SSL): `https://<host>/`
+- Management UI / API: `http://127.0.0.1:3000/` (bound to localhost)
+- Health: `http://127.0.0.1:3000/health` → `{"status":"ok"}`
+
+## How configuration works
+
+The app loads config via [`@simpleworkjs/conf`](https://www.npmjs.com/package/@simpleworkjs/conf),
+which deep-merges, in order:
+
+1. `conf/base.js` (committed defaults)
+2. `conf/<NODE_ENV>.js` (optional)
+3. `conf/secrets.js` (gitignored)
+4. **`app_*` environment variables** — the highest-precedence layer
+
+The bundled `docker-compose.yml` mounts `./config/proxy-secrets.js` at `/config`,
+and `docker-entrypoint.sh` sets `CONF_SECRETS=/config/proxy-secrets.js` so the
+app reads the OIDC + LDAP + auth wiring from the file. **No `app_*` env is
+passed** — `app_*` env beats `secrets.js`, so the file is authoritative only if
+the matching `app_*` env is absent. See `secrets.js.example` for the shape.
+
+Any env var starting with `app_` overrides the merged config; the rest of the
+name splits on **double-underscore** (`__`) into a nested path. Values are
+`JSON.parse`-coerced when possible, kept as strings otherwise. `app_*` env is
+still supported for advanced/standalone use — add the vars to the compose
+`environment:` block yourself (the bundled compose no longer sets them).
+
+> **Requires `@simpleworkjs/conf` >= 1.1.0.** The `app_*` env layer is not
+> honored on 1.0.0. The lock is already on `^1.1.0`.
+
+### Key `app_*` variables
+
+| Env var | Sets |
+|---------|------|
+| `app_oidc__issuer` | `conf.oidc.issuer` (browser-facing SSO URL) |
+| `app_oidc__authorizationEndpoint` | `conf.oidc.authorizationEndpoint` |
+| `app_oidc__tokenEndpoint` | `conf.oidc.tokenEndpoint` (server-to-server; can be internal) |
+| `app_oidc__userinfoEndpoint` | `conf.oidc.userinfoEndpoint` (server-to-server) |
+| `app_oidc__endSessionEndpoint` | `conf.oidc.endSessionEndpoint` |
+| `app_oidc__clientId` / `app_oidc__clientSecret` | OIDC client creds |
+| `app_oidc__redirectUri` | `conf.oidc.redirectUri` (must match the SSO client) |
+| `app_oidc__enabled` | `conf.oidc.enabled` (boolean) |
+| `app_ldap__url` | `conf.ldap.url` (`ldaps://…:636` or `ldap://…:389`) |
+| `app_ldap__bindDN` / `app_ldap__bindPassword` | LDAP service account |
+| `app_ldap__searchBase` / `app_ldap__userFilter` | user search |
+| `app_ldap__tlsOptions__rejectUnauthorized` | `false` for self-signed LDAPS |
+| `app_ldap__tlsOptions__ca` | path to a CA cert for strict trust |
+| `app_auth__adminUsers` | local anti-lockout admin (uid) |
+| `app_auth__adminGroups` | SSO/LDAP groups that are global admin (JSON array) |
+| `app_redis__prefix` | `conf.redis.prefix` (default `proxy_`) |
+
+See [`DEPLOYMENT.md`](https://github.com/theta42/proxy/blob/master/DEPLOYMENT.md)
+for the complete reference.
+
+## OpenResty runtime env
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `RESOLVER` | `127.0.0.11` | DNS for upstream names in Host records (Docker's embedded DNS) |
+| `REAL_IP_FROM` | _empty_ | Trusted CIDR for `X-Real-IP`. Empty = the proxy is the front (removes the real_ip block). Set to an upstream proxy's CIDR if one sits in front. |
+
+## Auto-SSL / Let's Encrypt
+
+`lua-resty-auto-ssl` stores certs in the bundled Redis. Redis is now AOF+RDB
+persisted to the `proxy-data` volume (not in-memory), so **Let's Encrypt certs
+survive container recreation** — no re-issue / rate-limit on rebuild. Port 80 is
+required for HTTP-01 challenges (mapped in the compose). Back up + restore Redis
+to back up + restore cert state (see *Backups and restore* in `DEPLOYMENT.md`).
+
+## Fronting an SSO Manager
+
+The proxy is a natural front for
+[`theta42/sso-manager-node`](https://github.com/theta42/sso-manager-node): it
+terminates TLS for the SSO's UI and protects it with OIDC login, while also
+binding to the SSO's LDAP directly for user lookups. To run both together:
+
+1. **One Docker network** so the proxy reaches the SSO internally at
+   `http://sso-manager:3001` (token/userinfo) and `ldaps://sso-manager:636`.
+2. **Set the SSO's `app_oauth__issuer`** to the browser-facing HTTPS URL the
+   proxy serves the SSO at (e.g. `https://sso.example.com`).
+3. **Register the proxy as an OIDC client** in the SSO, with `redirectUri`
+   matching `https://proxy.example.com/api/auth/oidc/callback`.
+4. **LDAP**: point `app_ldap__url` at `ldaps://sso-manager:636`, create a
+   dedicated service account (`cn=ldapclient,ou=people,…`), and for the SSO's
+   self-signed LDAPS cert set `app_ldap__tlsOptions__rejectUnauthorized=false`
+   (or mount the cert and use `app_ldap__tlsOptions__ca=<path>`).
+
+The [`theta42/theta-env`](https://github.com/theta42/theta-env) unified repo
+automates all four steps with `./setup.sh` — see
+[theta-env docs](https://theta42.github.io/theta-env/).
+
+## API tokens (personal access tokens)
+
+Any logged-in user can mint a long-lived bearer token to call the management API
+from scripts/CI without an OIDC browser session. Self-service; authenticates as
+the creator (groups snapshotted at mint; authz layer unchanged).
+
+Create one under **API Tokens** in the UI (shown once), then:
+
+```bash
+curl -H "Authorization: Bearer prx_<id>_<secret>" https://proxy.example.com/api/host
+```
+
+Rotate/revoke from the same page (immediate effect). Optional expiry at
+creation. The token carries the creator's rights (admin → full mgmt API;
+domain manager → those domains; `requireAdmin` routes 403). To tighten after
+group changes, revoke + re-mint. Tokens persist in Redis (AOF) and survive
+rebuilds.

+---
+
+# Proxy
+
+A reverse proxy and HTTPS termination service built on OpenResty/nginx, with a
+management API and web GUI. It puts any of your apps behind single sign-on
+(OIDC) and can also look users up directly in LDAP — so the same people who
+log in to your SSO are the people allowed to reach your proxied apps.
+
+Automatic HTTPS from Let's Encrypt (including wildcards), routing by hostname,
+and per-host access control tied to your identity provider — managed from a
+web UI or a REST API, with no downtime on config changes.
+
+Part of the theta42 self-hosted identity stack, alongside
+[SSO Manager](https://theta42.github.io/sso-manager-node/) and
+[theta-env](https://theta42.github.io/theta-env/) (the two composed with one
+command).

+
+Basic auth and SSO are mutually exclusive per host, with per-user password
+management once basic auth is enabled:

+
+## Why this over the alternatives
+
+Nginx Proxy Manager, Traefik, and Caddy are all good reverse proxies with
+auto-HTTPS. This one is built around identity: it is both an **OIDC client**
+of an SSO provider (for browser login) **and** a direct **LDAP client** (for
+user lookups and per-host access control), so access decisions come from your
+real user directory, not a static allow-list or a separate auth proxy bolted
+on top. The trade-off is that it expects an OIDC/LDAP identity source to point
+at — it is not a standalone auth server. Pair it with
+[SSO Manager](https://theta42.github.io/sso-manager-node/) (bundled OpenLDAP +
+OIDC) for a self-hosted SSO + proxy stack, or point it at any OIDC provider +
+LDAP directory you already run.
+
+## Features
+
+- Automated HTTPS via Let's Encrypt — HTTP-01 and DNS-01 (wildcard) challenges
+- Multiple DNS providers (Cloudflare, DigitalOcean, PorkBun, DuckDNS — free)
+- Dynamic host routing with wildcard domain matching (`*`, `**`)
+- **Multi-target load balancing** — configure multiple backend targets per host with built-in round-robin load balancing
+- **OIDC login** and **direct LDAP lookups**, independently of each other
+- Per-host **basic auth** as an alternative to SSO (mutually exclusive, so
+  it's never ambiguous which one gated a request)
+- **Role-based access control** — global admins, local groups, and
+  per-domain permissions (viewer/manager)
+- Self-service API tokens for scripting/CI without a browser session
+- Web UI and a full REST API
+
+## Get it
+
+```bash
+git clone https://github.com/theta42/proxy.git
+cd proxy && docker compose up -d --build
+```
+
+That's the standalone quick start. For the full set of install options (Docker,
+bare-metal, or as part of the combined SSO + proxy stack), configuration
+reference, and API docs, see the
+**[GitHub repository](https://github.com/theta42/proxy)**.

+
+## Quick Install (Recommended)
+
+For modern Debian-based systems (Ubuntu 20.04+, Debian 11+):
+
+```bash
+wget -O - https://raw.githubusercontent.com/theta42/proxy/master/ops/install.sh | sudo bash
+```
+
+This automated installer will:
+- Install Node.js 22.x
+- Install OpenResty and required dependencies
+- Install and configure Redis
+- Set up SSL fallback certificates
+- Install Lua dependencies
+- Clone and install the proxy application
+- Configure systemd service
+- Start the proxy service
+
+## Manual Installation
+
+> **Recommended path:** `ops/install.sh` (above) is idempotent and safe to
+> re-run — it symlinks the OpenResty/systemd config from the repo checkout,
+> so future updates stay in sync automatically (`git pull` + re-run). The
+> manual steps below *copy* those same files instead of symlinking them, so
+> they will **not** auto-track later changes to `ops/nginx_conf/` or
+> `ops/proxy.service` — you'd need to re-copy them by hand after every
+> update. Prefer the manual path only if `install.sh` doesn't fit your
+> distribution.
+
+### System Requirements
+
+- Modern Linux distribution (Ubuntu 20.04+, Debian 11+, or equivalent)
+- Root access
+- Inbound internet access for Let's Encrypt validation
+- Minimum 1GB RAM, 10GB disk space
+
+### Step 1: Install Dependencies
+
+**Ubuntu/Debian:**
+```bash
+apt install libpam0g-dev build-essential redis-server luarocks -y
+```
+
+### Step 2: Install Node.js 22.x
+
+```bash
+curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | \
+  sudo gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg
+
+NODE_MAJOR=22
+echo "deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_$NODE_MAJOR.x nodistro main" | \
+  sudo tee /etc/apt/sources.list.d/nodesource.list
+
+apt update && apt install nodejs -y
+```
+
+Verify installation:
+```bash
+node --version  # Should show v22.x.x
+npm --version
+```
+
+### Step 3: Install OpenResty
+
+openresty.org ships distinct trees (and components) for Debian and Ubuntu. The
+Debian tree is published only up to **bookworm** (there is no trixie block) and
+uses the **`openresty`** component; Ubuntu uses the host codename and **`main`**.
+So on a Debian 13 (trixie) host, point at the `bookworm` distribution (binary-
+compatible, same OpenSSL 3 era).
+
+```bash
+. /etc/os-release
+CODENAME="$(lsb_release -sc)"
+case "$ID" in
+  debian)
+    OR_PATH=package/debian
+    OR_COMPONENT=openresty
+    # Debian tree only publishes up to bookworm; fall back to it for trixie+.
+    case "$CODENAME" in jessie|stretch|buster|bullseye|bookworm) OR_DISTRO="$CODENAME";; *) OR_DISTRO=bookworm;; esac
+    ;;
+  *)
+    OR_PATH=package/ubuntu
+    OR_DISTRO="$CODENAME"
+    OR_COMPONENT=main
+    ;;
+esac
+
+wget -O - https://openresty.org/package/pubkey.gpg | \
+  sudo gpg --dearmor -o /usr/share/keyrings/openresty.gpg
+
+echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/openresty.gpg] http://openresty.org/${OR_PATH} ${OR_DISTRO} ${OR_COMPONENT}" | \
+  sudo tee /etc/apt/sources.list.d/openresty.list
+```
+
+> **Debian 13 (trixie):** apt's sequoia GPG backend rejects SHA-1 signatures by
+> default, and the OpenResty signing key is still SHA-1, so `apt update` will
+> refuse the repo. Extend the SHA-1 acceptance window before updating:
+> ```bash
+> sudo mkdir -p /etc/crypto-policies/back-ends
+> sudo cp /usr/share/apt/default-sequoia.config /etc/crypto-policies/back-ends/apt-sequoia.config
+> sudo sed -i 's/2026-02-01/2028-02-01/' /etc/crypto-policies/back-ends/apt-sequoia.config
+> ```
+> (The `default-sequoia.config` file only ships on Debian 13+, so this is a no-op
+> on older releases. `ops/install.sh` applies this automatically.)
+
+```bash
+apt update && apt install openresty -y
+```
+
+### Step 4: Install Lua Dependencies
+
+```bash
+luarocks install lua-resty-auto-ssl
+luarocks install luasocket
+```
+
+### Step 5: SSL Configuration
+
+Create fallback SSL certificates:
+
+```bash
+mkdir -p /etc/ssl/
+
+openssl req -new -newkey rsa:2048 -days 3650 -nodes -x509 \
+  -subj '/CN=sni-support-required-for-valid-ssl' \
+  -keyout /etc/ssl/resty-auto-ssl-fallback.key \
+  -out /etc/ssl/resty-auto-ssl-fallback.crt
+```
+
+### Step 6: Configure OpenResty
+
+Clone the repository and copy configuration files:
+
+```bash
+mkdir -p /opt/theta42
+cd /opt/theta42
+git clone https://github.com/theta42/proxy.git
+cd proxy
+
+# Copy nginx configs
+mkdir -p /etc/openresty/sites-enabled/
+cp ops/nginx_conf/nginx.conf /etc/openresty/nginx.conf
+cp ops/nginx_conf/autossl.conf /etc/openresty/autossl.conf
+cp ops/nginx_conf/proxy.conf /etc/openresty/sites-enabled/000-proxy
+cp ops/nginx_conf/targetinfo.lua /usr/local/openresty/lualib/targetinfo.lua
+```
+
+### Step 7: Install Application
+
+```bash
+cd /opt/theta42/proxy/nodejs
+npm install
+```
+
+### Step 7b: Configure Secrets
+
+```bash
+mkdir -p /etc/proxy
+cp /opt/theta42/proxy/secrets.js.example /etc/proxy/secrets.js
+chmod 600 /etc/proxy/secrets.js
+$EDITOR /etc/proxy/secrets.js   # set oidc.clientId/clientSecret, ldap.bindPassword, ...
+```
+
+`@simpleworkjs/conf` reads this file via the `CONF_SECRETS` env var, which the
+systemd unit below sets to `/etc/proxy/secrets.js`.
+
+### Step 8: Configure Systemd Service
+
+```bash
+cp /opt/theta42/proxy/ops/proxy.service /etc/systemd/system/proxy.service
+systemctl daemon-reload
+systemctl enable proxy.service
+systemctl start proxy.service
+```
+
+Verify service is running:
+```bash
+systemctl status proxy.service
+```
+
+### Step 9: Initial Setup
+
+The proxy API will be available on port 3000 by default. You'll need to:
+
+1. Create your first user account
+2. Configure DNS providers (for wildcard SSL)
+3. Add your first host
+
+See the [API Reference](api.html) for details.
+
+## Configuration
+
+### Environment Variables
+
+- `NODE_ENV` - Set to `production` for production deployments
+- `NODE_PORT` - Override default port (default: 3000)
+
+### Redis Configuration
+
+The proxy uses Redis with the prefix `proxy_`. To change this, edit `nodejs/conf/base.js`:
+
+```javascript
+redis: {
+  prefix: 'proxy_'
+}
+```
+
+### OpenResty Configuration
+
+Key configuration files in `/etc/openresty/`:
+- `nginx.conf` - Main nginx configuration
+- `autossl.conf` - Let's Encrypt HTTP-01 challenge handler
+- `sites-enabled/000-proxy` - Proxy server configuration
+
+### Unix Socket
+
+The proxy communicates with OpenResty via Unix socket at:
+```
+/var/run/proxy_lookup.socket
+```
+
+This path is configurable in `nodejs/conf/base.js`.
+
+## Troubleshooting
+
+### Service won't start
+
+Check logs:
+```bash
+journalctl -u proxy.service -f
+```
+
+Common issues:
+- Port 3000 already in use
+- Redis not running: `systemctl status redis-server`
+- Permission issues: Service must run as root for user management
+
+### SSL certificates not working
+
+Check OpenResty logs:
+```bash
+tail -f /var/log/nginx/error.log
+```
+
+Common issues:
+- Firewall blocking ports 80/443
+- DNS not pointing to server
+- Let's Encrypt rate limits exceeded
+
+### Host lookup not working
+
+Check Unix socket:
+```bash
+ls -la /var/run/proxy_lookup.socket
+# Should show srwxrwxrwx (socket permissions)
+```
+
+Test lookup:
+```bash
+echo '{"domain":"example.com"}' | nc -U /var/run/proxy_lookup.socket
+```
