Unix user the harness service runs as inside the container.
The meta-flake overrides this to the agent's own name so the
user inside the container matches the agent label (`HIVE_LABEL`).
Stand-alone evaluation defaults to `"agent"` so module evaluation
without the meta-flake wrapper still builds.
Constraints match `useradd`'s NAME_REGEX: lowercase / `_` start,
total length 31, no special characters. UID is auto-assigned

across rebuilds isn't a concern when the home and state dirs

same surface the previous root-user shape had, just elevated

When `true`, set `HIVE_WEB_SOCKET=/run/hive-agent/${userName}/web.sock`

`UnixListener` at that path instead of the legacy TCP listener
on `HIVE_PORT`.
Default `false` so an agent's web UI keeps binding TCP until
the per-agent flip is explicit. Rollout shape:
1. flip one canary agent to `true` via its `agent.nix`;
2. validate the gateway's `proxy_pass http://unix:.../web.sock`
end-to-end against that canary;
3. flip remaining agents per-agent as the gateway side soaks;
4. eventually drop this option once every agent is on unix and
the TCP fallback is removed from the harness.
Sub-agents only: the manager always has `HIVE_WEB_SOCKET` set
unconditionally in the `isManager` env block, so this toggle
has no effect when `hyperhive.role = "manager"`.

meta.rs flips this to `"manager"` for the manager container

Enable per-agent matrix integration via `hive-matrix-mcp`.

- runs `hive-matrix-daemon` as a systemd unit that holds a
matrix-sdk Client + sync against the homeserver at
`HIVE_MATRIX_URL` (default `http://localhost:8008` the
in-host tuwunel from `nix/modules/hive-matrix.nix`). The
daemon auto-skips when `<state>/matrix-token` is missing,
and a `systemd.paths` watcher restarts it the moment
hive-c0re provisions the token (same path-trigger shape
as `matrix-avatar-sync`).
- exposes the matrix tool surface (send_message, send_dm,
send_reaction, send_reply, mark_read, list_rooms,
list_room_members, read_room) to claude via an auto-injected
`extraMcpServers.matrix` entry. Claude spawns the stdio
`hive-matrix-mcp` bridge per turn, which forwards each tool
call to the daemon over `/run/hive-matrix/socket`.
- wakes the agent on incoming room events via a short teaser
Wake signal (`[matrix] <sender> in <room>: <first 100c>`)
to the hyperhive control socket; the full event stays
unread server-side until `read_room` consumes it.
Set to `false` for agents that should NOT have matrix tools at

both no-op cleanly anyway, so `false` is rarely necessary.

The default agent UI remains served at `/`; entries here only
add new routes and never replace the default. Overwrite
semantics are **hard-fail**: if `target` collides with an
existing file or directory in the default dist (or with a
prior entry's target), the `mergedDist` build aborts with
`refusing to overwrite existing path '<target>' in the
default dist`. To override a default file, fork the dist via
`hyperhive.frontend.dist` instead `extraFiles` is for
pure additions.
`target` must be a relative path inside the static dir. An

eval time (string-concat-into-paths safety, even though
agent.nix goes through operator review before deploy).
