atlas 89013b5408 agent permissions: hold hive-c0re's stored grant until the agent's own read
Until its first successful read of its key, the harness read its
permissions as the default set, `execution` included. So did the
subagent daemon. An agent the operator had narrowed ran wider than
granted after every restart while the queue was unreachable, and in the
gap before the first 10 s poll. During the meta-repo import, every
non-ruth key is still unset, and the agent read that as the default too,
for as long as the import stayed pending.

mara picked option (a) on #5293: "a, removal of the old path as a follow
up in 1w".

hive-c0re now writes each agent's entry from
swarm-agent-permissions.json into the agent's runtime dir as
swarm-permissions.json (/run/hive in the container), together with
whether the import is still pending. It writes the file at every start
(write_dropins) and after every 30 s pass of the permissions worker. The
harness and the subagent daemon hold that stored list until their own
first read succeeds. While the import is pending, an unset key keeps
the stored list rather than reverting it to the default. A queue that
is down never blocks a start: the agent runs on the stored grant.

The decision lives in swarm_queue_client::agent_permissions::HiveCopy,
shared by both readers.

Part of #5170.

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.
