`Coordinator::set_paused` wrote the marker directly with `std::fs::write`
from hive-c0re, which runs as the unprivileged `hive-core` user. The
agent's harness dir is chowned to the agent user on every container boot
(`user.nix`'s activation chown), mode 0755 — so hive-core can stat the
marker but gets EACCES creating or unlinking it. Pause therefore only
ever worked on an agent that had never booted; the read side works
because a stat needs traverse, not write, which is why the paused pill
and `is_paused` looked healthy.
Route both directions through hive-priv, the root helper that already
owns the other writes into agent-owned directories:
- `PrivRequest::SetAgentPaused { agent_name, paused }`, with the marker
filename constant moved to hive-priv-sock. That is the narrowest crate
all three sides share (hive-priv deliberately does not depend on
hive-sh4re, which re-exports it for the in-container resolver). A
private copy on any one side would break pause silently, since every
reader just sees "no marker".
- `write_agent_state_file` generalised to `write_agent_dir_file`, taking
the target directory: `state/` and `harness/` are both agent-owned,
which is the same reason both need root.
- resume unlinks via `remove_file`, which acts on the leaf and never
follows a symlink — an agent could otherwise plant a link at the
marker path and have root delete an arbitrary file.
`Coordinator::set_paused` becomes an async round-trip; its three call
sites were already async. Both directions stay idempotent because the
dashboard toggle and `hivectl pause|resume` fire without reading the
current state first.

hive-priv-sock
Wire types for the hive-priv privileged-helper socket
(/run/hive/priv.sock) — the contract between hive-priv (the root helper,
server) and hive-c0re (client, via its priv_client).
Why it's its own crate
Split out of hive-sh4re so hive-priv — a root-privileged binary —
depends on just this narrow protocol crate instead of the much larger
daemon-shared crate. Two wins: fewer dependencies in a root process's supply
chain, and a small, self-contained interface makes the privilege boundary this
crate encodes easier to audit. Mirrors hive-host-sock's split for the host
admin socket.
Shape
Serde-derived request/response types only — no server or client logic. Both
sides import them so the shapes stay in sync. See docs/boundary.md +
docs/security.md for the privilege boundary these types sit on, and
hive-priv/README for the helper itself.
