atlas 282bbc3709 feat(#2862): push a snapshot to a peer hive's store over the mesh
Adds the caller the fd-passing machinery existed for: hivectl agent
<name> subvol snapshot push --peer <hive> resolves the peer, connects
to its snapshot store, writes the agent header, and hands the connected
socket to hive-priv, which runs btrfs send straight into it.

The split keeps the root helper ignorant. Everything that involves
knowing where a peer is, what the wire protocol looks like, and which
hive to trust happens in the unprivileged daemon; hive-priv only ever
receives an already-open descriptor. Once btrfs send starts, neither
process is in the data path, so a multi-gigabyte transfer costs no
per-byte work and survives a hive-c0re restart.

call_with_fd takes the descriptor by value and closes it as soon as the
kernel has it. A socket stays open until every copy closes, so holding
one back would leave the receiver waiting for an EOF that never comes:
btrfs receive blocks and this side reports success for a transfer the
peer never committed. Ownership makes that unrepresentable.

The peer's store port is a new swarm.peers.<domain>.snapshotStorePort
option rather than a constant matching the module default. A pushing
hive cannot read the receiver's configuration, so assuming 51821 would
push at a port nobody promised to listen on; absent, the push fails
naming the option. swarm_peers parses the mesh address the host module
has always rendered into HYPERHIVE_PEERS but nothing read.

hivectl

The operator-facing host CLI. A thin client for the hive-c0re daemon — speaks the host admin socket protocol (hive-host-sock) and does not link the daemon crate. Container lifecycle, the approval queue, and provisioning verbs all forward to the daemon and need it running; a few (wg/peer-config, choom) work off local host state instead.

When to use it

Reach for this crate when adding an operator-run host command — agents talk to the daemon over their own MCP tool surface (hive-agent-mcp), not this binary. hivectl is what a human operator (or a host-side script) runs.

Shape

One module per subcommand family; main.rs is just the clap parse + dispatch:

  • agents.rs — container lifecycle (spawn/kill/rebuild/restart/…).
  • approvals.rs — the config/init-config/meta-input approval queue.
  • dag_progress.rs — rebuild-queue progress rendering.
  • power.rs — restart/start/stop at the container level.
  • choom.rs — drop into an interactive claude session in a container.
  • forge.rs, matrix.rs, github.rs, gateway.rs — per-integration account/token provisioning.
  • wg.rs — WireGuard mesh helpers.
  • subvol.rs — btrfs state-subvolume ops.
  • quota.rs, util.rs, completions.rs, open.rs — shared helpers, shell completions, browser-open.
