A paused agent keeps its container, its claude session and its
dashboard/todo servers up, but stops driving turns. Messages queue
unacked and are drained on resume.
The whole protocol is a single marker file, `<harness>/paused`. That
directory is already a bind-mount shared between host and container, so
both sides just stat the same path: the harness reads it to decide
whether to drive a turn, hive-c0re reads it to render the badge and
writes/removes it for `hivectl pause|resume`. No new wire protocol, no
container round-trip, and it is sticky across restarts by construction.
Not calling `recv_next` while paused *is* the queueing semantic, so
there is no fencing to get wrong: reminders buffer in their unbounded
channel, the todo `Notify` permit coalesces, and a `request_next_turn`
that raced the pause survives because the gate sits above
`self_continue.take()`.
Graceful stop is handled host-side rather than in the harness: a paused
agent provably has no turn in flight, so `run_signal` skips the fence
entirely instead of eating the full `GRACEFUL_STOP_TIMEOUT` waiting for
a checkpoint turn that will never run.
`paused` is reported on `ContainerView` / `AgentStatusRow` for the
dashboard, orthogonal to `running` and reported for stopped containers
too.
Closes: hyperhive/hyperhive issue 2271
The host admin socket `/run/hyperhive/host.sock` was `0660 root:root` (no
SocketGroup), so hivectl needed sudo. Group-own it by a new `hive-admin`
group and add a `services.hyperhive.c0re.adminUsers` allowlist: listed users
join `hive-admin` and drive hivectl without root.
- `SocketGroup = "hive-admin"`, `SocketMode = "0660"` on the hive-c0re.socket
unit.
- `/run/hyperhive` -> `0751` (traverse-only, no listing) so the group can reach
the socket path; the socket's own `0660 hive-admin` mode gates the
connection, and the per-agent subdirs keep their own restrictive perms.
- Empty `adminUsers` (the default) leaves `hive-admin` memberless -> root-only,
as before.
The admin socket is full hive control (spawn/kill/destroy/deploy), so
`adminUsers` is an explicit, opt-in trust grant. Documented in
docs/boundary.md (host admin socket access) + docs/tools/hivectl.md.
hivectl has verbs scattered across CLAUDE.md and domain docs (gateway.md
has the gateway subcommands, matrix.md has a brief mention) but no
single cheatsheet. Add docs/tools/hivectl.md covering all subcommands:
- forge create-user: provision/refresh agent or human forge accounts
- matrix create-user / sync-admin / promote-user / reset-password
- gateway create-user / delete-user / list-users (htpasswd management)
- agents restart / restart-all (container lifecycle via admin socket)
- choom <name> [--fresh]: interactive claude session in agent container
Also add a reading-path entry to CLAUDE.md pointing at the new file.
