- Daemon: factor the terminal command into terminal_command(); add `--selftest`
which opens the host terminal PTY locally and prints ~2.5s of raw output, so
you can confirm tmux/zsh actually draws on a given node without the browser.
(Verified locally: tmux spawns zsh + draws its status bar.)
- cm-api: temporary [fleet-term] eprintln tracing in open_terminal, the pty_out
router, and the browser bridge (byte counts + sink presence) to locate where
output stops between daemon→server→browser. To be removed once diagnosed.

The node terminal opened a bare bash PTY — bash prints its prompt once, so a
freshly-attached xterm showed nothing. Switch to `tmux new-session -A -s
clawmates` on the HOST (mirrors the agent terminal, but on the node itself, not
in a container): tmux redraws the whole screen on attach (no blank), and the
session is resumable across reopens. Starts in $HOME. Falls back to a login
shell if tmux is unavailable. ensure_tmux() best-effort installs tmux via the
host package manager when the daemon runs as root (systemd); otherwise logs a
hint to `apt install tmux`. Rebuilt + re-hosted both binaries.

Hostname/IP:
- Daemon reports the machine's hostname (sysinfo) + primary outbound IPv4 on each
heartbeat. migrations/0021 adds nodes.hostname/local_ip; cm-db heartbeat stores
them; node JSON exposes them. Cards now title on the real hostname (falling back
to name) + show the IP, instead of the "New node" placeholder. `name` stays
user-overridable (rename).
Terminal moved into the pull-out computer (no more per-card modal):
- New infra computer app NodeTerminalApp (computer/apps/infra) — xterm bridged to
a node's host shell over the node control channel, filling the app window
(mirrors the agent Terminal's layout + ResizeObserver). Added "terminal" to the
INFRA_CATALOG grid; a ?node= panel param targets a specific node (picker when
unset). Clicking Terminal on a node card now opens the infra computer to that
node's shell instead of a separate full-screen window. Deleted NodeTerminal.tsx.
Rebuilt + re-hosted both daemon binaries (hostname change).

Two bugs surfaced running the daemon on a real node:
- Linking cm-sandbox (bollard) brought a second rustls provider into the graph,
so rustls couldn't auto-pick one and panicked at the WSS TLS handshake. Install
the ring provider explicitly at startup (rustls dep + install_default()).
- The daemon auto-ran `tailscale set --ssh`, which tries to reroute the user's
live SSH session and aborts ("will result in your session disconnecting"). Now
Tailscale is only touched when an auth key is explicitly passed (opt-in), with
--accept-risk=lose-ssh to avoid the interactive abort.
Rebuilt + re-hosted both binaries (linux-amd64, darwin-arm64).

Agents can now provision their sandbox on a connected fleet node instead of the
gateway host. Local stays the strict default, so existing agents are byte-for-
byte unaffected until explicitly placed elsewhere.
Security parity: the daemon links the REAL cm-sandbox DockerDriver and runs the
typed container ops (sb_provision/sb_exec/sb_destroy/sb_health/sb_list) through
it — identical hardening (cap-drop ALL, seccomp, no-net, read-only, non-root) to
local sandboxes. cm-sandbox spec types are now Serialize/Deserialize so the spec
crosses the channel.
- cm-api: RemoteDriver (impl SandboxDriver over the node channel) + HubDriverProvider
(impl cm_runtime::NodeDriverProvider, hands out a driver only for connected
nodes via a sync online set) + NodeHub.call/is_connected. AppState.with_node_hub
so the hub is shared with the placement provider.
- cm-runtime SandboxManager: driver_for(node_id) routes by the recorded
agent_containers.node_id (local default = existing driver, identical path);
placement_node() reads the workspace setting and falls back to local if the
node is offline; exec/release route accordingly. NodeDriverProvider trait.
- DB: 0020_workspace_placement + repo (for_agent/get/set/clear).
- main.rs: build the NodeHub first; inject HubDriverProvider into the agent
manager + share the hub with AppState.
- API+UI: GET/PUT /api/fleet/placement + a "Run agents on: Local / <node>"
selector in the Fleet overview.
Note: a node must be able to pull the agent image (the daemon docker-pulls it);
interactive PTY for agent containers on remote nodes is not wired (Terminal app
stays local) — the in-dashboard node shell already covers host access.

Proves a connected node can host hardened agent workloads end-to-end, without
touching the agent run loop (zero blast radius on existing agents).
- Daemon: typed `sb_check` op — pulls a tiny image and runs it fully locked down
(cap-drop ALL, no-new-privileges, no network, read-only rootfs, non-root,
memory/pids caps), then tears it down. Fixed command; nothing caller-supplied
runs (preserves the exec-hardening invariant).
- cm-api: NodeHub.sandbox_check + POST /api/nodes/{id}/sandbox-check.
- UI: a shield "sandbox check" button on each online node card streams the
result (✓ SANDBOX READY + container id/uname).
This validates the full provision→run→destroy mechanism on nodes. The remaining
P2 work — wiring real agent deploys to auto-place onto nodes — is its own
subsystem (a RemoteDriver reusing the local DockerDriver for security parity,
agent-image distribution to nodes, and node-routing in SandboxManager) and is
best done as a focused pass; it is intentionally NOT bundled here to keep the
core agent path untouched.

You can now open a real shell on any connected node from the dashboard — the
daemon spawns a host PTY and streams it over the existing outbound control
channel (no inbound port, no Tailscale brokering needed).
Daemon:
- portable-pty host shell sessions: pty_open/pty_in/pty_resize/pty_close ops; a
reader thread streams base64 pty_out frames. Outbound frames now funnel through
one mpsc channel so PTY output and heartbeats interleave.
cm-api NodeHub:
- per-connection pty_sinks + sid multiplexing; open_terminal/terminal_input/
terminal_resize/terminal_close; in-memory single-use terminal tickets (the
browser WS can't carry a bearer, and the session is instance-local anyway).
- routes/nodes.rs: POST /api/nodes/{id}/terminal/ticket + GET .../terminal/ws
(bridges browser xterm <-> node PTY: binary = keystrokes, text = resize).
Frontend:
- NodeTerminal xterm modal (reuses the agent Terminal's xterm setup); a Terminal
button on each online node card opens a shell.
This proves the bidirectional streaming-over-channel mechanism the RemoteDriver
will reuse. Remaining P2: RemoteDriver + placement (run agent workloads on nodes).

Security hardening:
- The gateway no longer sends arbitrary shell to nodes. The WSS exec op is
replaced by a typed `verify` op the daemon runs itself (fixed host+docker
check); future container ops are typed too. cm-api NodeHub.verify() + the
daemon's handle_command only dispatches vetted ops.
BYO Tailscale:
- migrations/0019_workspace_tailscale.sql + cm-db fleet_tailscale repo (store the
user's Tailscale API key + tailnet, server-side only).
- cm-api routes/tailscale.rs: POST/GET/DELETE /api/fleet/tailscale + GET
/api/fleet/tailscale/devices (proxies api.tailscale.com device list).
- Daemon: --tailscale-authkey → `tailscale up --authkey … --ssh` (enables
Tailscale SSH for keyless user access); else `tailscale set --ssh=true`. Reports
its tailscale IP (already).
UI:
- Fleet overview gains a Tailscale section: connect (key+tailnet) + live tailnet
device status (online/last-seen/IP/os). Node cards show a copyable Tailscale SSH
target (ssh <ip>).
Remaining: P2 — RemoteDriver + placement (run agents on nodes) and the in-UI
remote terminal (PTY proxied over the WSS channel).
