Closes #1585.

What changed

  • publish the broker-owned live WorkerName set in a reserved capability on the existing node heartbeat, independent of agent/provider registration and workspace-roster writes
  • decode those names for remote fleet nodes and label missing, malformed, or count-mismatched snapshots as degraded
  • make fleet agent list --node X an exact local filter that skips the workspace roster entirely
  • explicitly advertise --json and keep JSON as the default output

Mechanism proof

A temporary broker built from this branch ran on sf-mini. Its node record first reported activeAgents: 0 and metadata.names: []; after spawning one disposable PTY, both became 1 and ["relay-1585-e2e-sf-0820"], matching the OS process table. The new decoder rendered that exact name. Release returned the set to empty on the next heartbeat. The temporary worker, broker, and directory were removed.

This also falsified provider registration and historical node-agent bindings as reliable live-name sources; no workspace roster is used for targeted output.

Validation

  • 46 focused CLI tests, including the required must-fire/must-not-fire filter pair
  • 5 broker heartbeat tests
  • Prettier, cargo fmt --check, changed-file TypeScript check, and git diff --check

📝 Walkthrough

Walkthrough

The broker now publishes active worker names in heartbeat capabilities. The CLI decodes these names for remote fleet listings, applies strict node filtering, excludes roster-only agents, and reports degraded inventory states.

Changes

Remote live-agent listing

Layer / File(s) Summary
Heartbeat worker-name publication
crates/broker/src/fleet_wire.rs, crates/broker/src/node_control.rs, crates/broker/src/runtime/...
Fleet load snapshots now carry active worker names. Heartbeats publish sorted, deduplicated names through relay:live-agents:v1.
Remote-agent decoding and rendering
packages/cli/src/cli/commands/fleet-agent.ts, packages/cli/src/cli/commands/fleet-agent.test.ts
The CLI validates and sorts heartbeat names, renders named remote rows, and reports unsupported, malformed, mismatched, or incomplete data.
Fleet filtering and orchestration
packages/cli/src/cli/commands/fleet.ts, packages/cli/src/cli/commands/fleet.test.ts
Targeted queries filter visible nodes, skip roster retrieval, exclude roster-only agents, and retain local-node handling.
Validation and release records
tests/e2e/fleet/fleet-e2e.test.ts, .gitattributes, CHANGELOG.md, .agentworkforce/trajectories/...
Tests, changelog entries, diff attributes, and trajectory records were updated.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to d032b

The change makes targeted fleet-agent listing use live heartbeat names, but whitespace-only names can still pass validation and render as a blank NAME entry. This is a bounded display and correctness issue for malformed node metadata; the PR is otherwise mergeable with explicit owner awareness or follow-up.

Poem

A rabbit checks the heartbeat stream,
Where worker names now neatly gleam.
Node filters keep the roster tight,
Sorted rows report live states right.
When counts and names disagree,
Degraded notes explain what we see.

Add cases for two uncovered remote branches.

Two new user-visible branches in buildRows have no test:

  1. remoteWarning propagation. A contribution with remoteWarning set must produce a row note containing degraded: <warning>.
  2. activeAgents === undefined with an empty name list. That path renders <node inventory returned no names; active count unavailable> with presence count only (degraded).

Both are cheap to add next to the existing mismatch tests.

1492-1497: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Four copies of the active worker-name collection. Every fleet-load publication site inlines workers.workers.keys().map(|name| name.as_str().to_string()).collect() next to workers.workers.len(). The shared root cause is a missing WorkerRegistry accessor that pairs the count with the name list. If one site later diverges, the CLI reports a false heartbeat reports N, broker returned M mismatch on that node.

Add WorkerRegistry::active_worker_names() and call it at each site:

64-70: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Reject whitespace-only names as malformed.

The guard accepts any non-empty string. A name of ' ' passes validation and reaches sanitizeCell, which does not strip spaces. The row then renders with a blank NAME cell, which reads the same as an error row. Trim before the check so a whitespace-only entry is counted as malformed instead of rendered as an agent.

-      if (typeof rawName !== 'string' || !rawName || names.has(rawName)) {

Scenario: publish_fleet_load_snapshot (crates/broker/src/runtime/fleet.rs:1830) calls fleet_control_tx.try_send(FleetControlCommand::UpdateLoad(...)) from BrokerRuntime::maintenance_tick (crates/broker/src/runtime/maintenance.rs:729-742) after a worker change. If the mpsc channel is full at that instant, the snapshot is dropped and the very next heartbeat emits the previous active_agent_names.

Not changing this — the design is intentional coalescing, and the reader-side label handles the transient window:

  1. Capacity is 256 (crates/broker/src/runtime/init.rs:310). Reaching that means ~256 unprocessed commands are queued for run_node_control_client. In steady state this is impossible; if the node-control loop is that far behind, its own send_wire for heartbeats and pings is also failing, and the READ_IDLE_TIMEOUT guard (crates/broker/src/node_control.rs:1874-1885) forces a reconnect within ~4 heartbeat intervals. On reconnect, RegisterNode re-seats load.max_agents/load.handlers_live from the manifest, and the next publish_fleet_load seeds a fresh WorkerName set.

  2. UpdateLoad is periodic state, not an event log. The receiver stores *load = next (crates/broker/src/node_control.rs:1828), and every heartbeat tick reads the current load (crates/broker/src/node_control.rs:1885). A dropped snapshot causes at most one stale-name heartbeat; the very next spawn/release/reap re-emits with workers.workers.keys().collect(). Retain-and-retry would duplicate the coalescing the receiver already provides.

  3. The CLI labels the transient explicitly. buildRows (packages/cli/src/cli/commands/fleet-agent.ts) compares node.activeAgents against the decoded relay:live-agents:v1 names and, on any divergence, renders count only (degraded) with the note degraded: heartbeat reports N, broker returned M. An operator reading fleet agent list during that window sees degraded, not a silent stale list.

The finding names a real narrow window; it does not name a silent stale-forever failure. The queue size, the reconnect guard, and the CLI degradation label together make this a labelled degraded window, which is the invariant this PR was written to hold.

P2: When the fleet-control queue is full during a spawn or release, active_agent_names is dropped and every subsequent heartbeat advertises the previous WorkerName set. Deliver this authoritative live-name snapshot reliably, or retain and retry the latest pending load update, so remote fleet agent list cannot remain stale indefinitely.

This is the same finding as crates/broker/src/runtime/maintenance.rs:732, directed at the field on the snapshot type. Full response is on that thread; short version:

  • The active_agent_names field is coalesced periodic state, not an event-log entry. Every subsequent spawn/release/reap in BrokerRuntime::publish_fleet_load (crates/broker/src/runtime/fleet.rs:1489-1509) or maintenance_tick (crates/broker/src/runtime/maintenance.rs:729-742) re-emits with a fresh workers.keys().collect().
  • The fleet_control_tx channel is capacity 256 (crates/broker/src/runtime/init.rs:310); reaching it means the node-control task is far enough behind that the read-idle guard (crates/broker/src/node_control.rs:1874-1885) fires reconnect within ~4 heartbeat intervals, and RegisterNode reseeds load on the new connection.
  • The CLI already labels the transient — buildRows (packages/cli/src/cli/commands/fleet-agent.ts) renders count only (degraded) with degraded: heartbeat reports N, broker returned M whenever node.activeAgents and the decoded WorkerName set disagree. Operators do not read a stale window as a confirmed list.

Retain-and-retry on the sender would duplicate the coalescing the receiver already provides (*load = next at crates/broker/src/node_control.rs:1828), without changing the observable degraded-labelled window.

P3: This complete code-fix PR (relay#1585) ships its tracked Trail trajectory still parked under .agentworkforce/trajectories/active/traj_rb4zzwul9nse/trajectory.json with status: "active" and no completedAt/retrospective/chapter endedAt, and no summary.md/.trace.json artifacts. The implementation, validation, and mechanism proof in the PR description are finished, so the trail should be finalized with trail complete: set status to "completed", add completedAt and the retrospective, move the trajectory to .agentworkforce/trajectories/completed/2026-08/traj_rb4zzwul9nse/, and preserve the generated summary.md and .trace.json. Leaving completed work under active/ breaks the repository's audit-history convention.

Addressed in e418a9c7.

The trajectory has been finalized with trail complete and moved to .agentworkforce/trajectories/completed/2026-08/traj_rb4zzwul9nse/. Status is now completed, completedAt and the retrospective are set on trajectory.json, and the generated summary.md and traj_rb4zzwul9nse.trace.json sit next to it. .agentworkforce/trajectories/active/traj_rb4zzwul9nse/ is gone.

Warn when `fleet agent list --node <name>` skips the workspace roster
fetch, so the PRESENCE column's `remote live` value on those rows is
labelled as node-local liveness only rather than reading as a confirmed
non-membership. Same finding on both fleet.ts:461 and fleet.ts:479.

Split the changelog entry into three impact-first bullets and drop the
"from each broker's live worker map" implementation backstory to match
the repository's changelog conventions.
