+# Delegation/split-domain deployment
+
+Matrix allows clients and servers to discover a homeserver's "true" destination via **`.well-known` delegation**. This is especially useful if you would like to:
+
+- Serve Continuwuity on a subdomain while having only the base domain for your usernames
+- Use a port other than `:8448` for server-to-server connections
+
+This guide will show you how to have `@user:example.com` usernames while serving Continuwuity on `https://matrix.example.com`. It assumes you are using port 443 for both client-to-server connections and server-to-server federation.
+
+## Configuration
+
+First, ensure you have set up A/AAAA records for `matrix.example.com` and `example.com` pointing to your IP.
+
+Then, ensure that the `server_name` field matches your intended username suffix. If this is not the case, you **MUST** wipe the database directory and reinstall Continuwuity with your desired `server_name`.
+
+Then, in the `[global.well_known]` section of your config file, add the following fields:
+
+```toml
+[global.well_known]
+
+client = "https://matrix.example.com"
+
+# port number MUST be specified
+server = "matrix.example.com:443"
+
+# (optional) customize your support contacts
+#support_page =
+#support_role = "m.role.admin"
+#support_email =
+#support_mxid = "@user:example.com"
+```
+
+Alternatively if you are using Docker, you can set the `CONTINUWUITY_WELL_KNOWN` environment variable as below:
+
+```yaml
+services:
+  continuwuity:
+    ...
+    environment:
+      CONTINUWUITY_WELL_KNOWN: |
+        {
+        client=https://matrix.example.com,
+        server=matrix.example.com:443
+        }
+```
+
+## Serving with a reverse proxy
+
+After doing the steps above, Continuwuity will serve these 3 JSON files:
+
+- `/.well-known/matrix/client`: for Client-Server discovery
+- `/.well-known/matrix/server`: for Server-Server (federation) discovery
+- `/.well-known/matrix/support`: admin contact details (strongly recommended to have)
+
+To enable full discovery, you will need to reverse proxy these paths from the base domain back to Continuwuity.
+
+<details>
+
+<summary>For Caddy</summary>
+
+```
+matrix.example.com:443 {
+  reverse_proxy 127.0.0.1:8008
+}
+
+example.com:443 {
+  reverse_proxy /.well-known/matrix* 127.0.0.1:8008
+}
+```
+
+</details>
+
+<details>
+
+<summary>For Traefik (via Docker labels)</summary>
+
+```
+services:
+  continuwuity:
+    ...
+    labels:
+      - "traefik.enable=true"
+      - "traefik.http.routers.continuwuity.rule=(Host(`matrix.example.com`) || (Host(`example.com`) && PathPrefix(`/.well-known/matrix`)))"
+      - "traefik.http.routers.continuwuity.service=continuwuity"
+      - "traefik.http.services.continuwuity.loadbalancer.server.port=8008"
+```
+
+</details>
+
+Restart Continuwuity and your reverse proxy. Once that's done, visit these routes and check that the responses match the examples below:
+
+<details open>
+
+<summary>`https://example.com/.well-known/matrix/server`</summary>
+
+```json
+{
+  "m.server": "matrix.example.com:443"
+}
+```
+
+</details>
+
+<details open>
+
+<summary>`https://example.com/.well-known/matrix/client`</summary>
+
+```json
+{
+  "m.homeserver": {
+    "base_url": "https://matrix.example.com/"
+  }
+}
+```
+
+</details>
+
+## Troubleshooting
+
+### Cannot log in with web clients
+
+Make sure there is an `Access-Control-Allow-Origin: *` header in your `/.well-known/matrix/client` path. While Continuwuity serves this header by default, it may be dropped by reverse proxies or other middlewares.
+
+---
+
+## Using SRV records (not recommended)
+
+:::warning
+The following methods are **not recommended** due to increased complexity with little benefits. If you have already set up `.well-known` delegation as above, you can safely skip this part.
+:::
+
+The following methods uses SRV DNS records and only work with federation traffic. They are only included for completeness.
+
+<details>
+
+<summary>Using only SRV records</summary>
+
+If you can't set up `/.well-known/matrix/server` on :443 for some reason, you can set up a SRV record (via your DNS provider) as below:
+
+- Service and name: `_matrix-fed._tcp.example.com.`
+- Priority: `10` (can be any number)
+- Weight: `10` (can be any number)
+- Port: `443`
+- Target: `matrix.example.com.`
+
+On the target's IP at port 443, you must configure a valid route and cert for your server name, `example.com`. Therefore, this method only works to redirect traffic into the right IP/port combo, and can not delegate your federation to a different domain.

+
+<summary>Using SRV records + .well-known</summary>
+
+You can also set up `/.well-known/matrix/server` with a delegated domain but no ports:
+
+```toml
+[global.well_known]
+server = "matrix.example.com"
+```
+
+Then, set up a SRV record (via your DNS provider) to announce the port number as below:
+
+- Service and name: `_matrix-fed._tcp.matrix.example.com.`
+- Priority: `10` (can be any number)
+- Weight: `10` (can be any number)
+- Port: `443`
+- Target: `matrix.example.com.`
+
+On the target's IP at port 443, you'll need to provide a valid route and cert for `matrix.example.com`. It provides the same feature as pure `.well-known` delegation, albeit with more parts to handle.

+
+<details>
+
+<summary>Using SRV records as a fallback for .well-known delegation</summary>
+
+Assume your delegation is as below:
+
+```toml
+[global.well_known]
+server = "example.com:443"
+```
+
+If your Continuwuity instance becomes temporarily unreachable, other servers will not be able to find your `/.well-known/matrix/server` file, and defaults to using `server_name:8448`. This incorrect cache can persist for a long time, and would hinder re-federation when your server eventually comes back online.
+
+If you want other servers to default to using port :443 even when it is offline, you could set up a SRV record (via your DNS provider) as follows:
+
+- Service and name: `_matrix-fed._tcp.example.com.`
+- Priority: `10` (can be any number)
+- Weight: `10` (can be any number)
+- Port: `443`
+- Target: `example.com.`
+
+On the target's IP at port 443, you'll need to provide a valid route and cert for `example.com`.

+Get a working Continuwuity server with an admin user in four steps:
+
+#### Prerequisites
+
+Continuwuity requires HTTPS for Matrix federation. You'll need:
+
+- A domain name pointing to your server
+- A reverse proxy with SSL/TLS certificates (Traefik, Caddy, nginx, etc.)
+
+See [Docker Compose](#docker-compose) for complete examples.
+
+#### Environment Variables
+
+- `CONTINUWUITY_SERVER_NAME` - Your Matrix server's domain name
+- `CONTINUWUITY_DATABASE_PATH` - Where to store your database (must match the
+  volume mount)
+- `CONTINUWUITY_ADDRESS` - Bind address (use `0.0.0.0` to listen on all
+  interfaces)
+- `CONTINUWUITY_ALLOW_REGISTRATION` - Set to `false` to disable registration, or
+  use with `CONTINUWUITY_REGISTRATION_TOKEN` to require a token (see
+  [reference](../reference/environment-variables.mdx#registration--user-configuration)
+  for details)
+
+See the
+[Environment Variables Reference](../reference/environment-variables.mdx) for
+more configuration options.
+
+#### 1. Pull the image
 
 ```bash
-docker run -d -p 8448:6167 \
+docker pull forgejo.ellis.link/continuwuation/continuwuity:latest
-    -v db:/var/lib/continuwuity/ \
-    -e CONTINUWUITY_SERVER_NAME="your.server.name" \
-    -e CONTINUWUITY_ALLOW_REGISTRATION=false \
-    --name continuwuity $LINK
 ```
 
-or you can use [Docker Compose](#docker-compose).
+#### 2. Start the server with initial admin user
 
-The `-d` flag lets the container run in detached mode. You may supply an
+```bash
-optional `continuwuity.toml` config file, the example config can be found
+docker run -d \
-[here](../reference/config.mdx). You can pass in different env vars to
+  -p 6167:6167 \
-change config values on the fly. You can even configure Continuwuity completely by
+  -v continuwuity_db:/var/lib/continuwuity \
-using env vars. For an overview of possible values, please take a look at the
+  -e CONTINUWUITY_SERVER_NAME="matrix.example.com" \
-<a href="/examples/docker-compose.yml" target="_blank">`docker-compose.yml`</a> file.
+  -e CONTINUWUITY_DATABASE_PATH="/var/lib/continuwuity" \
+  -e CONTINUWUITY_ADDRESS="0.0.0.0" \
+  -e CONTINUWUITY_ALLOW_REGISTRATION="false" \
+  --name continuwuity \
+  forgejo.ellis.link/continuwuation/continuwuity:latest \
+  /sbin/conduwuit --execute "users create-user admin"
+```
 
-If you just want to test Continuwuity for a short time, you can use the `--rm`
+Replace `matrix.example.com` with your actual server name and `admin` with
-flag, which cleans up everything related to your container after you stop
+your preferred username.
-it.
+
+#### 3. Get your admin password
+
+```bash
+docker logs continuwuity 2>&1 | grep "Created user"
+```
+
+You'll see output like:
+
+```
+Created user with user_id: @admin:matrix.example.com and password: `[auto-generated-password]`
+```
+
+#### 4. Configure your reverse proxy
+
+Configure your reverse proxy to forward HTTPS traffic to Continuwuity. See
+[Docker Compose](#docker-compose) for examples.
+
+Once configured, log in with any Matrix client using `@admin:matrix.example.com`
+and the generated password. You'll automatically be invited to the admin room
+where you can manage your server.

+reverse proxy configurations for Matrix federation.
 
-Depending on your proxy setup, you can use one of the following files:
+#### Matrix Federation Requirements
 
-### For existing Traefik setup
+For Matrix federation to work, you need to serve `.well-known/matrix/client` and
+`.well-known/matrix/server` endpoints. You can achieve this either by:
+
+1. **Using a well-known service** - The compose files below include an nginx
+   container to serve these files
+2. **Using Continuwuity's built-in delegation** (easier for Traefik) - Configure
+   delegation files in your config, then proxy `/.well-known/matrix/*` to
+   Continuwuity
+
+**Traefik example using built-in delegation:**
+
+```yaml
+labels:
+  traefik.http.routers.continuwuity.rule: >-
+    (Host(`matrix.example.com`) ||
+     (Host(`example.com`) && PathPrefix(`/.well-known/matrix`)))
+```
+
+This routes your Matrix domain and well-known paths to Continuwuity.
+
+#### Creating Your First Admin User
+
+Add the `--execute` command to create an admin user on first startup. In your
+compose file, add under the `continuwuity` service:
+
+```yaml
+services:
+    continuwuity:
+        image: forgejo.ellis.link/continuwuation/continuwuity:latest
+        command: /sbin/conduwuit --execute "users create-user admin"
+        # ... rest of configuration
+```
+
+Then retrieve the auto-generated password:
+
+```bash
+docker compose logs continuwuity | grep "Created user"
+```
+
+#### Choose Your Reverse Proxy
+
+Select the compose file that matches your setup:
+
+:::note DNS Performance
+Docker's default DNS resolver can cause performance issues with Matrix
+federation. If you experience slow federation or DNS timeouts, you may need to
+use your host's DNS resolver instead. Add this volume mount to the
+`continuwuity` service:
+
+```yaml
+volumes:
+  - /etc/resolv.conf:/etc/resolv.conf:ro
+```
+
+See [Troubleshooting - DNS Issues](../troubleshooting.mdx#potential-dns-issues-when-using-docker)

-
-The images *do not contain a shell*. They contain only the Continuwuity binary, required libraries, TLS certificates, and metadata.

-# Build for the current platform and load into the local Docker daemon
-docker buildx build --load --tag continuwuity:latest -f docker/Dockerfile .
-
-# Example: Build for specific platforms and push to a registry.
-# docker buildx build --platform linux/amd64,linux/arm64 --tag registry.io/org/continuwuity:latest -f docker/Dockerfile . --push
-
-# Example: Build binary optimised for the current CPU (standard release profile)
-# docker buildx build --load \
-#   --tag continuwuity:latest \
-#   --build-arg TARGET_CPU=native \
-#   -f docker/Dockerfile .
-
-# Example: Build maxperf variant (release-max-perf profile with LTO)
-# Optimised for runtime performance and smaller binary size, but requires longer build time
-# docker buildx build --load \
-#   --tag continuwuity:latest-maxperf \
-#   --build-arg TARGET_CPU=native \
-#   --build-arg RUST_PROFILE=release-max-perf \
-#   -f docker/Dockerfile .

-

-### Use Traefik as Proxy
+### Building Custom Images
 
-As a container user, you probably know about Traefik. It is an easy-to-use
+For information on building your own Continuwuity Docker images, see the
-reverse proxy for making containerized apps and services available through the
+[Building Docker Images](../development/index.mdx#building-docker-images)
-web. With the Traefik-related docker-compose files provided above, it is equally easy
+section in the development documentation.
-to deploy and use Continuwuity, with a small caveat. If you have already looked at
-the files, you should have seen the `well-known` service, which is the
-small caveat. Traefik is simply a proxy and load balancer and cannot
-serve any kind of content. For Continuwuity to federate, we need to either
-expose ports `443` and `8448` or serve two endpoints: `.well-known/matrix/client`
-and `.well-known/matrix/server`.
-
-With the service `well-known`, we use a single `nginx` container that serves
-those two files.
-
-Alternatively, you can use Continuwuity's built-in delegation file capability. Set up the delegation files in the configuration file, and then proxy paths under `/.well-known/matrix` to continuwuity. For example, the label ``traefik.http.routers.continuwuity.rule=(Host(`matrix.ellis.link`) || (Host(`ellis.link`) && PathPrefix(`/.well-known/matrix`)))`` does this for the domain `ellis.link`.

 ## Building Docker Images
 
-To build a Docker image for Continuwuity, use the standard Docker build command:
+Official Continuwuity images are built using **Docker Buildx** and the
+Dockerfile found at [`docker/Dockerfile`][dockerfile-path].
+
+The images are compatible with Docker and other container runtimes like Podman
+or containerd.
+
+The images _do not contain a shell_. They contain only the Continuwuity binary,
+required libraries, TLS certificates, and metadata.

+# Space Permission Cascading — Design Document
+
+**Date:** 2026-03-17
+**Status:** Approved
+
+## Overview
+
+Server-side feature that allows user rights in a Space to cascade down to its
+direct child rooms. Includes power level cascading and role-based room access
+control. Enabled via a server-wide configuration flag, disabled by default.
+
+## Requirements
+
+1. Power levels defined in a Space cascade to all direct child rooms (Space
+   always wins over per-room overrides).
+2. Admins can define custom roles in a Space and assign them to users.
+3. Child rooms can require one or more roles for access.
+4. Enforcement is continuous — role revocation auto-kicks users from rooms they
+   no longer qualify for.
+5. Users are auto-joined to all qualifying child rooms when they join a Space or
+   receive a new role.
+6. Cascading applies to direct parent Space only; no nested cascade through
+   sub-spaces.
+7. Feature is toggled by a single server-wide config flag
+   (`space_permission_cascading`), off by default.
+
+## Configuration
+
+```toml
+# conduwuit-example.toml
+
+# Enable space permission cascading (power levels and role-based access).
+# When enabled, power levels cascade from Spaces to child rooms and rooms
+# can require roles for access. Applies to all Spaces on this server.
+# Default: false
+space_permission_cascading = false
+```
+
+## Custom State Events
+
+All events live in the Space room.
+
+### `m.space.roles` (state key: `""`)
+
+Defines the available roles for the Space. Two default roles (`admin` and `mod`)
+are created automatically when a Space is first encountered with the feature
+enabled.
+
+```json
+{
+  "roles": {
+    "admin": {
+      "description": "Space administrator",
+      "power_level": 100
+    },
+    "mod": {
+      "description": "Space moderator",
+      "power_level": 50
+    },
+    "nsfw": {
+      "description": "Access to NSFW content"
+    },
+    "vip": {
+      "description": "VIP member"
+    }
+  }
+}
+```
+
+- `description` (string, required): Human-readable description.
+- `power_level` (integer, optional): If present, users with this role receive
+  this power level in all child rooms. When a user holds multiple roles with
+  power levels, the highest value wins.
+
+### `m.space.role.member` (state key: user ID)
+
+Assigns roles to a user within the Space.
+
+```json
+{
+  "roles": ["nsfw", "vip"]
+}
+```
+
+### `m.space.role.room` (state key: room ID)
+
+Declares which roles a child room requires. A user must hold **all** listed
+roles to access the room.
+
+```json
+{
+  "required_roles": ["nsfw"]
+}
+```
+
+## Enforcement Rules
+
+All enforcement is skipped when `space_permission_cascading = false`.
+
+### 1. Join gating
+
+When a user attempts to join a room that is a direct child of a Space:
+
+- Look up the room's `m.space.role.room` event in the parent Space.
+- If the room has `required_roles`, check the user's `m.space.role.member`.
+- Reject the join if the user is missing any required role.
+
+### 2. Power level override
+
+For every user in a child room of a Space:
+
+- Look up their roles via `m.space.role.member` in the parent Space.
+- For each role that has a `power_level`, take the highest value.
+- Override the user's power level in the child room's `m.room.power_levels`.
+- Reject attempts to manually set per-room power levels that conflict with
+  Space-granted levels.
+
+### 3. Role revocation
+
+When an `m.space.role.member` event is updated and a role is removed:
+
+- Identify all child rooms that require the removed role.
+- Auto-kick the user from rooms they no longer qualify for.
+- Recalculate and update the user's power level in all child rooms.
+
+### 4. Room requirement change
+
+When an `m.space.role.room` event is updated with new requirements:
+
+- Check all current members of the room.
+- Auto-kick members who do not hold all newly required roles.
+
+### 5. Auto-join on role grant
+
+When an `m.space.role.member` event is updated and a role is added:
+
+- Find all child rooms where the user now meets all required roles.
+- Auto-join the user to qualifying rooms they are not already in.
+
+This also applies when a user first joins the Space — they are auto-joined to
+all child rooms they qualify for. Rooms with no role requirements auto-join all
+Space members.
+
+### 6. New child room
+
+When a new `m.space.child` event is added to a Space:
+
+- Auto-join all qualifying Space members to the new child room.
+
+## Caching & Indexing
+
+The source of truth is always the state events. The server maintains an
+in-memory index for fast enforcement lookups, following the same patterns as the
+existing `roomid_spacehierarchy_cache`.
+
+### Index structures
+
+| Index                        | Source event           |
+|------------------------------|------------------------|
+| Space → roles defined        | `m.space.roles`        |
+| Space → user → roles         | `m.space.role.member`  |
+| Space → room → required roles| `m.space.role.room`    |
+| Room → parent Space          | `m.space.child` (reverse lookup) |
+
+The Space → child rooms mapping already exists.
+
+### Cache invalidation triggers
+
+| Event changed              | Action                                              |
+|----------------------------|-----------------------------------------------------|
+| `m.space.roles`            | Refresh role definitions, revalidate all members    |
+| `m.space.role.member`      | Refresh user's roles, trigger auto-join/kick        |
+| `m.space.role.room`        | Refresh room requirements, trigger auto-join/kick   |
+| `m.space.child` added      | Index new child, auto-join qualifying members       |
+| `m.space.child` removed    | Remove from index (no auto-kick)                    |
+| Server startup             | Full rebuild from state events                      |
+
+## Admin Room Commands
+
+Roles are managed via the existing admin room interface, which sends the
+appropriate state events under the hood and triggers enforcement.
+
+```
+!admin space roles list <space>
+!admin space roles add <space> <role_name> [description] [power_level]
+!admin space roles remove <space> <role_name>
+!admin space roles assign <space> <user_id> <role_name>
+!admin space roles revoke <space> <user_id> <role_name>
+!admin space roles require <space> <room_id> <role_name>
+!admin space roles unrequire <space> <room_id> <role_name>
+!admin space roles user <space> <user_id>
+!admin space roles room <space> <room_id>
+```
+
+## Architecture
+
+**Approach:** Hybrid — state events for definition, database cache for
+enforcement.
+
+- State events are the source of truth and federate normally.
+- The server maintains an in-memory cache/index for fast enforcement.
+- Cache is invalidated on relevant state event changes and fully rebuilt on
+  startup.
+- All enforcement hooks (join gating, PL override, auto-join, auto-kick) check
+  the feature flag first and no-op when disabled.
+- Existing clients can manage roles via Developer Tools (custom state events).
+  The admin room commands provide a user-friendly interface.
+
+## Scope
+
+### In scope
+
+- Server-wide feature flag
+- Custom state events for role definition, assignment, and room requirements
+- Power level cascading (Space always wins)
+- Continuous enforcement (auto-join, auto-kick)
+- Admin room commands
+- In-memory caching with invalidation
+- Default `admin` (PL 100) and `mod` (PL 50) roles
+
+### Out of scope
+
+- Client-side UI for role management
+- Nested cascade through sub-spaces
+- Per-space opt-in/opt-out (it is server-wide)
+- Federation-specific logic beyond normal state event replication

+# Environment Variables
+
+Continuwuity can be configured entirely through environment variables, making it
+ideal for containerised deployments and infrastructure-as-code scenarios.
+
+This is a convenience reference and may not be exhaustive. The
+[Configuration Reference](./config.mdx) is the primary source for all
+configuration options.
+
+## Prefix System
+
+Continuwuity supports three environment variable prefixes for backwards
+compatibility:
+
+- `CONTINUWUITY_*` (current, recommended)
+- `CONDUWUIT_*` (compatibility)
+- `CONDUIT_*` (legacy)
+
+All three prefixes work identically. Use double underscores (`__`) to represent
+nested configuration sections from the TOML config.
+
+**Examples:**
+
+```bash
+# Simple top-level config
+CONTINUWUITY_SERVER_NAME="matrix.example.com"
