atlas 07852cabc1 feat(3088): move the gateway's nginx + dnsmasq onto the host 
The gateway's nginx + dnsmasq no longer run in their own nspawn container.
`nix/host-modules/hive-gateway/default.nix` loses the
`containers.hive-gateway` wrapper and everything that existed only to punch
holes in it: `privateNetwork = false`, `CAP_NET_ADMIN`, five bind mounts,
its own `stateVersion`, `networking.firewall.enable = false`,
`networking.resolvconf.enable = false`, and the `hive-gateway-resolv`
path+service pair. 465 -> 303 lines.

The container never bought isolation here. It shared the host netns by
necessity — nginx binds the host's :80/:443, dnsmasq answers on the bridge —
so each of those settings was undoing a boundary the gateway could not
afford in the first place.

Four things made it more than a deletion, none of them visible in the nix
diff:

- The self-signed cert service also imports the hive CA leaf, so removing it
  with the container would have left nginx naming a missing cert file, which
  it refuses to load at all.
- The nginx reload is a hive-priv verb. It still needs root, but no longer
  for the reason its doc gave, and `--machine=` was both transport and
  scope — so the unit name is now hard-coded in the helper as the
  containment.
- The lifecycle verb named a container that stops existing.
- `journalctl -M hive-gateway` had no machine to enter.

Per the operator's ruling, the operator verb keeps working and agents lose
it. `InfraContainer` answered three questions that used to share an answer;
it now splits into `name()` (identity), `target()` (Container vs HostUnit),
`service_unit()` (the systemd unit), and `agent_restartable()`, which the
MCP restart path checks before the capability so the refusal cannot read as
"ask for infra_admin". `SIBLING_CONTAINERS` drops the gateway — it gates the
requests that name a container as a string — while `FromStr` still accepts
it, because that answers what a name is, not who may act on it. The
dashboard's gateway journal reads host journald filtered to `nginx.service`.

Prose was corrected where it only named a location, and re-argued where the
container was doing security work: a `0666` per-agent socket was safe
because only the gateway container had the directory bind-mounted. There is
no mount now, so the directory permissions are the whole of the access
control — the constraint holds, its mechanism doesn't.

Gate: nix fmt / clippy --all-targets -D warnings / cargo test all clean (710
tests); hivectl-cli.md regenerated from the clap tree. The nix eval was run
in both TLS shapes at this commit: every delta in the rendered
virtualHosts is one of the three intended path moves, dnsmasq settings are
byte-identical, and the absence probe flips true -> false with bindMounts
emptied.

README.md

hive-agent

The in-container harness serve-loop binary — one instance per agent. Long-polls the broker inbox and drives one claude --print turn per inbox message, over the hive-claude driver. There is one role here (agent); the Surface trait + AgentSurface zero-sized type tag keep the turn loop generic and testable for future roles without a parallel copy of the loop.

When to use it

You don't call into this crate from elsewhere — it's the top-level binary systemd starts per agent container. Look here when you need to understand or change: what happens between "a message lands in the inbox" and "claude produces a reply", how login/auth is bootstrapped, how the per-agent web UI is served, or how turn/event stats get recorded. Architecture detail lives in docs/turn-loop/; this README is just the map of the module tree.

Shape

  • turn.rs — the turn-loop policy layer: renders the system prompt + MCP config, invokes hive-claude, classifies the outcome, and feeds the event/turn-stats sinks.
  • client.rs — broker client (inbox poll, ack, send) speaking the hive-sh4re wire protocol.
  • login.rs / login_session.rs — first-run and session-resume auth flow for the claude CLI.
  • mcp_config.rs — renders the per-turn --mcp-config / --allowedTools blob from tool groups + capabilities.
  • todos.rs / reminders.rs / todo_server.rs — the harness-local loose-ends v2 stores (sqlite-backed) and the in-agent socket server extra MCP daemons + hive-agent-mcp dial into for todo/reminder ops.
  • vacuum.rs — periodic sqlite vacuum sweep for the harness-local stores.
  • events.rs / turn_stats.rs / stats.rs — append-only event sink and per-turn telemetry recording (context usage, cost, tool favorites) under harness/.
  • forge_notify.rs — subscribes to forge notifications and wakes the harness on new activity.
  • prompt.rs — system-prompt renderer (persona + tool docs + environment facts).
  • web_ui/ — the per-agent dashboard (terminal pane, status, schedules) served over the built-in hive-agent web port.
  • paths.rs — canonical path resolution for state/harness dirs and the harness-local sqlite files.

Sibling: hive-agent-mcp (the MCP server this loop points claude at every turn). Both are described together in docs/turn-loop/::Harness binary shape.
