atlas 3fc1588e83 fix: declare the agent socket dir's owner in tmpfiles, not by chown after 
/run/hive-agent/<name> was 0777 root root in steady state, not just during
first spawn. A directory without the sticky bit lets any user unlink files
in it, and the gateway container has all of /run/hive-agent bind-mounted
in, so anything that could reach the path could delete an agent's
agent.sock, bind its own, and receive that agent's todos from hive-c0re.

Two mechanisms were writing the dir and undoing each other: the tmpfiles.d
entry wrote 0777 root root, then hive-c0re round-tripped through hive-priv's
ChownSocketDir to narrow it. `d` re-asserts mode and owner on every apply
and the file is regenerated on any agent's spawn or destroy, so every such
event reset every agent's dir back to world-writable.

SyncAgentTmpfiles now carries each agent's container uid/gid and the entry
declares the answer: 0751 <uid> <gid>. Three principals need the dir and no
two share a group -- the harness binds its sockets (owner rwx), hive-c0re
dials agent.sock and the gateway's nginx dials web.sock (both only need
traverse, and both sockets are already 0666).

Deletes ChownSocketDir and ChmodSocketDir, both priv_client wrappers, the
either/or in host_config with its two swallowed warn!s, and the now-dead
socket_dir_path -- two verbs off the privileged helper's surface and one
round-trip off every agent spawn.

Also makes the two tmpfiles rules for /run/hive-agent itself agree: the
gateway module said hive-core, the generated file said root, and which won
depended on the order systemd read them in.

hive-c0re

The unprivileged host daemon (runs as hive-core). Owns the sqlite broker, the approval/question/schedule queues, the generic job-DAG queue, container lifecycle, gateway/forge/matrix provisioning, per-container stats, and the axum operator dashboard. Largest crate in the workspace — bin-only, no separate lib.

When to use it

Host-level, cross-container orchestration: spawning/rebuilding/ destroying agent containers, the approval flow, dashboard-visible state, provisioning per-agent forge/matrix/gateway accounts. Agent-side behavior (turn loop, MCP tools) lives in hive-agent/hive-agent-mcp instead — this daemon only talks to agents over the socket wire types in hive-sh4re.

Shape

Cohesive clusters live in directory submodules, each re-exported at the crate root (crate::broker::… keeps resolving regardless of which subdirectory a module actually lives in). One line each — read the module's own //! doc-comment for real detail, don't expect this file to track it:

  • dashboard/ — the operator dashboard (containers, approvals, schedules, questions, logs, topology).
  • job_queue/ — the job-DAG queue + desired-state reconciliation (docs/coordinator.md).
  • lifecycle/ — nixos-container lifecycle + per-agent config flake generation.
  • stores/ — sqlite-backed stores (broker, queues, audit, power).
  • workers/ — background sweeps (crash watch, scheduled prompts, auto-update, knowledge sync).
  • agent_config/ — per-agent registries (tool groups, capabilities, resource limits, topology).
  • stats/ — dashboard metrics aggregation + OTEL export.
  • socket_server/ — the unix-socket request server shared by per-agent + manager sockets.
  • forge/ — optional Forgejo wiring (docs/forge.md).
  • coordinator.rs — top-level wiring for serve.
  • meta.rs, migrate.rs — the meta flake + schema/state migrations.
  • matrix.rs, gateway_nginx.rs, webhook_secret.rs, priv_client.rs — matrix provisioning, gateway vhosts, webhook secrets, and the hive-priv client respectively.
