atlas 1f214f9f01 bound the request line on the host admin and in-agent sockets 
hive-c0re's admin socket and hive-agent's in-agent socket (mode 0666) read
the request with an unbounded read_line: no length cap and no deadline, so
a peer that never sends a newline grows a buffer and pins a task forever.

The bounded reader (16 MiB cap) moves from hive-c0re's socket_server into
hive-sock-client, the one crate both daemons already share or can take, and
gains optional deadlines for the first byte and for the rest of the line.
Both sockets now use it and answer an over-long or stalled line with the
same error reply the bounded sockets give, then close. The admin socket
bounds only the started line (clients may idle between requests); the
in-agent socket is single-shot and bounds silence too. The per-agent
sockets keep their behaviour (no deadline).

hive-agent

The in-container harness serve-loop binary — one instance per agent. Long-polls the broker inbox and drives one turn per inbox message through hive-runtime, on the agent's runtime (claude --print by default, or an ACP agent). It has one role (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 landing in the inbox and the agent's reply, how the harness bootstraps login/auth, how it serves the per-agent web UI, 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

  • main.rs — the serve loop and the Surface trait; broker calls (inbox poll, ack, send) go through hive-sock-client with hive-core-agent-sock wire types.
  • turn.rs — the turn-loop policy layer: renders the system prompt + MCP config, runs the turn through hive-runtime, classifies the outcome, and feeds the event/turn-stats sinks.
  • 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 the agent's permissions.
  • 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/.
  • 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.

Siblings: hive-agent-mcp (the MCP server this loop points the agent at every turn) and hive-runtime (the library a turn runs through). docs/turn-loop/::Harness binary shape covers all three together.
