# Private Matrix homeserver (matrix-tuwunel — the official conduwuit
# successor) for hyperhive agents, wrapped in a nixos-container so it
# doesn't fight any existing `services.matrix-*` the operator may
# already run on the host. Same shape as `nix/modules/hive-forge.nix`:
# shared host netns (`privateNetwork = false`) so agents reach it at
# `http://localhost:<httpPort>` (or via the configured server_name
# for federation), nixos-container only here for state + systemd-unit
# isolation.
#
# Container name `hive-matrix` (not `h-*`) so the lifecycle scanner
# ignores it; operator manages via the standard `nixos-container` CLI.
#
# Persistent state at `/var/lib/nixos-containers/hive-matrix/var/lib/
# matrix-tuwunel/` (survives container restart / host reboot). To
# wipe, destroy the container.
#
# Initial rollout (#548): federation enabled (needed for multi-hive
# swarms; trusted_servers starts empty so no actual federation traffic
# leaves until peers are explicitly listed), registration via admin
# API only, e2ee disabled per operator call (tracked for follow-up at
# #551).

Run hive-matrix — a private matrix-tuwunel homeserver (in a
nixos-container) for hyperhive agents. Off by default while
the integration phases in; flip to `true` once the operator
has set `hyperhive.domain` and is ready to onboard agents.

matrix-tuwunel package to run inside the container. Defaults
to nixpkgs's `pkgs.matrix-tuwunel`. Override to pin a
specific upstream if you need an unreleased feature.

Matrix `server_name` — the host part of every user ID
(`@argus:<server_name>`) and room ID minted on this
homeserver. CRITICAL: must be stable from day one because
it's embedded irrevocably in the identifiers. Defaults to
`matrix.''${hyperhive.domain}` (always a subdomain — keeps
the root domain free for the dashboard or forge). Override
here only if you need a name that doesn't follow the
`matrix.<domain>` shape.

TCP port tuwunel serves the matrix client-server API on.
Default 8008 is the matrix-spec well-known port. Sits
outside hyperhive's claimed ranges (dashboard 7000, manager
8000, sub-agents 8100..8999). Federation listens on
`federationPort` separately.

openFirewall = lib.mkOption {

default = true;
description = ''
Open `httpPort` in the host firewall. Off when the
homeserver should only be reachable from inside the host
(e.g. while bringing the integration up before announcing
it to other hives).
Note: federation (the matrix-spec well-known port 8448) is
intentionally not opened here. tuwunel serves the federation
API on the same `httpPort` as the client-server API by
default; reaching it on 8448 requires either binding tuwunel
to that port explicitly OR a reverse-proxy + `.well-known/
matrix/server` delegation, neither of which lives in this
module. Add that proxy config alongside whatever serves your
dashboard or forge on 443.

description = ''
List of trusted matrix servers (homeservers whose signing
keys this server will fetch identity-server-style). Empty
by default — federation is enabled at the protocol level
but no peer is trusted until listed here, so the homeserver
is effectively closed until the operator declares hive
peers explicitly.

hyperhive.matrix.enable = true requires either:

(recommended; shared with forge / dashboard), or
- hyperhive.matrix.serverName set explicitly.
The matrix server_name is embedded into every user ID and
room ID on this homeserver — it cannot be changed later
without losing every account and chat history. Pick a
stable hostname before enabling.
