feat(fleet): B4.3 — per-mission rootfs selection (missions.backend)
`vm_create` takes a backend name and boots `rootfs-<backend>.ext4`; NULL or "default" boots the golden image. Makes the per-CLI images from B4.1 actually reachable (one image per CLI, per A6). A missing image is an ERROR naming the file and how to build it, never a quiet fall back to the default. That fallback is the tempting version and the wrong one: it would run a claude mission in a kimi VM, or in a rootfs with no CLI at all, and report success for whatever came out. Verified on real hardware, not just in a unit test — the selftest asks for an image that does not exist and FAILS if it boots. `create` now reports the rootfs that actually booted, not the one that was requested, so a mission artifact can show the wrong VM ran. The migration adds no CHECK constraint listing the CLIs. Which images exist is a property of the NODES, not the schema; a constraint would need migrating for every new image while still not guaranteeing the image exists anywhere. The node validates and names what is missing. Backend names are `[A-Za-z0-9_-]` and rejected rather than sanitised, since they become filenames. Verified on tank: default backend 8/8; `CLAWMATES_FC_BACKEND=agent-terminal` 9/9 including the absent-image check, create in 910ms on a rootfs built from a real Docker image. 435 tests green, no leaked processes or VM dirs.

feat(fleet): B2 — vm_* node ops for Firecracker microVMs
create / inject / exec / collect / destroy / list, riding the node's
existing frame dispatch ({t, id, …} -> {t:"result", id, ok, output}), so
no protocol change was needed. Control is length-prefixed JSON over
vsock; the serial console stays a log, because feeding a guest over stdin
races its startup and arrives half-consumed.
DEVIATION FROM THE PLAN, deliberately: this does NOT implement
cm_sandbox::SandboxDriver. That trait is container-shaped —
attach_pty/resize_pty/argv exec — while missions need
create -> inject -> run -> collect -> destroy. Conforming would mean
building PTY-over-vsock and window-resize semantics that no mission path
calls, purely to satisfy a signature. We give up automatic RemoteDriver
marshalling; orphan reaping is a label/id sweep either way.
Three traps from the B0 spike are handled in code rather than remembered:
- Firecracker does NOT unlink its vsock UDS on exit, so destroy unlinks
it explicitly, and the selftest ASSERTS it is gone. Assuming the VM
tidies up after itself is how the mission checkout accumulated four
uid bugs.
- firecracker is spawned via setsid and killed as a process GROUP, so a
background child cannot outlive the VM holding its workdir open.
- create does not return until the guest agent has answered a ping. A
VM that booted but serves nothing is worse than one that failed, so a
half-created VM is destroyed rather than left registered.
A vm id becomes a path component, so ids are restricted to [A-Za-z0-9_-]
and REJECTED rather than sanitised — a caller that sent `../../etc`
wanted something we should not guess at.
Verified on tank through the real Rust path, as the daemon user, with no
sudo: `clawmates-node --vm-selftest` -> 8/8, create in 986ms, and the
host left with zero firecracker processes and zero VM directories. The
selftest asserts every step, including that a destroyed VM can no longer
be exec'd; a test that only reports the steps it completed cannot
distinguish "passed" from "stopped early".

Fleet terminal: WebRTC DataChannel direct path (low-latency) + WS fallback
Terminal keystrokes were ~400ms because every byte relayed browser→Cloudflare→
gw-04 (Europe)→tailscale→node, even when the node is on the user's own LAN. Add a
direct browser↔node WebRTC DataChannel so co-located terminals run at LAN speed;
the gateway is reduced to signaling; the WebSocket relay stays as the automatic
fallback (graceful degradation — never worse than before).
Daemon (clawmates-node v0.4.0, new src/rtc.rs):
- Add the `webrtc` crate (reuses the ring crypto provider we already install — no
conflict). Browser is the offerer; we answer, trickle ICE back over the control
channel, and on DataChannel open spawn a host PTY (tmux) bridged DIRECTLY to the
channel. Refactor open_pty → spawn_terminal_pty shared by both transports.
iceServers: STUN + auto host/tailnet candidates (direct, no relay, for LAN/tailnet).
Server (cm-api):
- NodeConn.signal_sinks; Uplink WebRtcAnswer/WebRtcIce/WebRtcFailed routed to the
browser; NodeHub webrtc_offer/ice/close + open_session/open_pty (open_terminal
split so the PTY opens only once the transport is chosen). bridge_terminal relays
signaling over the existing ticket-authed WS and opens the relay PTY on
{type:"fallback"}.
Browser (NodeTerminalApp):
- RTCPeerConnection + reliable/ordered DataChannel; offer/answer/ICE over the WS;
2.5s race → use the DataChannel if it opens, else fall back to the WS relay.
Reconnect wraps both. A direct⚡/relayed indicator shows the live transport.
Deployed; both nodes (morpheus, tank) updated to v0.4.0 and steady online. Direct-
path proof is a browser action (the ⚡ indicator + latency); confirmable from the
daemon's [rtc] logs.

Fleet: robust real-time connectivity + mosh-inspired reconnecting terminal
Nodes flapped online/offline and the terminal died on the first blip. WebSockets are the right transport (outbound, NAT-friendly); the fixes harden around it. Server (cm-api): - Anti-clobber connection epoch: a reconnecting daemon gets a fresh epoch; a stale run_channel's teardown only clears the hub + sets offline if it still owns the slot — so a lingering old channel can't flip a live reconnection offline (the main false-offline cause). - WS keepalive: run_channel now pings every 15s and tears down if no inbound frame (incl. pong) for 35s — dead links detected in seconds, not minutes. - Staleness sweeper backstop: spawn_node_sweeper (8s tick / 20s window) wired in clawmates-server, so a vanished node goes offline within ~28s even if its channel hangs (mark_stale_offline was defined but never called). Daemon (clawmates-node v0.3.0): - Heartbeats off the select thread (dedicated thread owns System + blocking docker/tailscale/disk CLIs) so a slow op never starves heartbeats/pongs. - Each handle_frame runs on its own task; added a 40s inbound idle deadline so a half-open socket triggers a reconnect. Frontend: - useNodes streams /api/nodes/live (SSE push) instead of a 3s poll; isLive() derives online from lastSeen freshness (<15s) so a transient column flip never shows a healthy node down. - Node terminal: clean auto-reconnect loop (re-mint ticket -> reconnect -> tmux re-attaches and redraws the live screen = mosh-style snap-to-state over TCP), replacing the [disconnected] dead-end. Mosh evaluated: harvest principles (session/transport decoupling, snap-to-state, already given by tmux), don't adopt — UDP is incompatible with our browser+CF+NAT topology and it's GPLv3. Removed temporary terminal debug traces + /api/debug route. Verified: node holds steadily online (heartbeat 1-3s, no flap) and goes cleanly offline when the daemon stops.

Fleet terminal: fix tmux nesting-refusal + frontend resize storm
Root cause (from the server trace: 69 banner bytes then immediate "to_browser
ended" = pty_exit): tmux spawned and exited instantly, writing its "sessions
should be nested with care" warning to stderr (not the PTY). The operator runs
the daemon inside their own tmux, so $TMUX was inherited and the spawned tmux
refused to nest → browser saw nothing.
- daemon (v0.2.2): spawn tmux on a DEDICATED socket (`tmux -L clawmates
new-session -A -s main`) and `env_remove("TMUX")`, so it can never collide with
or be refused by the operator's tmux.
- NodeTerminalApp: debounce the ResizeObserver (150ms). The pull-out animates
open, firing the observer on every pixel — previously ~80 resize frames per
open, each fit()+SIGWINCH. Now one resize after layout settles.

Fleet terminal: daemon self-diagnosis + immediate banner + debug route
The server trace showed pty_open is sent but the daemon (morpheus, v0.2.0) emits
no pty_out — so the PTY spawn was dying silently. Instrument it:
- daemon open_pty: log open/tmux/first-read/EOF/error/total to stdout, and send
an IMMEDIATE banner pty_out ("[clawmates] host shell on <host> — starting…") so
the browser confirms the relay even before the shell draws. If open_pty fails,
send the error as pty_out (was a silent pty_exit). Bump to v0.2.1.
- cm-api: temp GET /api/debug/node-pty/{id}?dbg=… opens a node terminal and reads
~2s of output with no browser/auth, to test the relay in isolation.
- NodeTerminalApp + ticket/ws routes already log each hop ([node-term]/[fleet-term]).
Diagnostic logic: banner shows + shell doesn't → relay ok, shell is the problem;
nothing shows → relay broken; daemon "EOF after N bytes" → shell exited.

clawmates-node: fix rustls CryptoProvider panic + non-intrusive Tailscale
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).

Fleet P2b: run agent sandboxes on connected nodes (RemoteDriver + placement)
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.

Fleet P2a: in-dashboard remote terminal (PTY over the WSS channel)
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).

Fleet P0: node registry + daemon + health + connect-host wizard
Users can connect their own local-hardware nodes into a fleet. Each node runs a
new Rust daemon that dials home over an outbound WebSocket, reports host health,
and runs commands we send.
Backend:
- migrations/0018_fleet_nodes.sql: nodes + node_health tables + agent_containers
(node_id, workspace_id) index. cm-domain NodeId.
- cm-db repo/nodes.rs: create/auth/list+health/get/heartbeat/set_status/delete
(unchecked sqlx, no .sqlx regen).
- cm-api fleet.rs NodeHub: live daemon channels (node_id→sender) + the WS channel
runner (heartbeat→DB upsert, exec request/response framing). routes/nodes.rs:
POST /pair, GET /nodes, SSE /nodes/live, POST /{id}/exec-test, DELETE /{id},
WS /nodes/agent (token-auth). Wired into AppState + router.
Daemon (new crate crates/bins/clawmates-node):
- sysinfo host metrics (cpu/mem/pressure/swap/disk/load/containers), outbound WSS
dial + reconnect, heartbeat loop, exec command handling, tailscale-ip probe.
install.sh convenience installer.
Frontend:
- Fleet sidebar item + FleetOverview + LocalHardware node-health cards (live via
/api/nodes, 3s poll) + ConnectHostWizard (install → verify connection →
exec-test). InfraStage dispatches fleet/local; default selection = fleet.
Deferred: P1 (BYO Tailscale + network metrics), P2 (RemoteDriver + placement so
agents actually run on connected nodes).
