fix(sdk): omit stale active-agent load for offline nodes

[miyaontherelay]

Summary

Port the missing SDK half of relay#1610 onto current main. toRelayNode now omits activeAgents when live === false or status is offline, preserving numeric zero for a live node. Relaycast can retain a stale numeric load after provider loss; zero is a measurement, not an unknown sentinel.

The broker reconnect half and RelayFlow case 1591-application-ack-reconnect are already in main from #1770. The old offlineNode helper is retained only as a local assertion in the messaging test; no additional production helper is needed. relayflow_application_ack_reconnect_probe and #1610 trajectory files are omitted: the former belongs to #1770's broker reconnect proof, while this PR has its own SDK RelayFlow case.

• Change type: bugfix
• RelayFlow case: 1610-sdk-node-load-liveness

Validation

• SDK focused tests (messaging.test.ts, relaycast-translate.test.ts): 24 passed.
• Full SDK suite: 179 passed, 3 pre-existing failures in agent-relay.test.ts workspace-setup mocks; those failures are unrelated to this translation change.
• Diff excludes .agentworkforce/trajectories.

No merge was performed.

Note

Low Risk
Narrow SDK mapping change; activeAgents was already optional and consumers should treat omission as unknown load.

Overview
Fixes SDK node translation so stale activeAgents counts are not surfaced after a provider goes offline or when liveness is not confirmed.

toRelayNode now sets activeAgents only when live === true and status is not offline, so a retained wire value of 0 is not treated as a real measurement for unreachable nodes. A live online node with zero agents still reports activeAgents: 0.

Tests in messaging.test.ts and a dedicated relaycast-translate.test.ts cover offline, live-zero, and unconfirmed-liveness cases. RelayFlow case 1610-sdk-node-load-liveness proves base vs head behavior in CI.

📝 Walkthrough

Walkthrough

toRelayNode now omits activeAgents for offline or non-live nodes. Live online nodes retain measured zero values. SDK tests and a relay-flow case cover the behavior.

Changes

Node load liveness

Layer / File(s)	Summary
Liveness-aware SDK normalization packages/sdk/src/messaging/relaycast-translate.ts, packages/sdk/src/__tests__/*	toRelayNode normalizes status and omits activeAgents when the node is offline or not live. Tests cover list results, lookups, and live zero values.
Relay-flow regression coverage tests/relayflows/cases/1610-sdk-node-load-liveness/*	The new relay-flow case, probe, and runner verify that the base arm reports the bug and the head arm omits offline-node load.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~15 minutes

Change: Bug fix

Merge Risk: ⚪ Minimal · up to ce26c

The SDK now withholds stale node-load values when liveness is not confirmed while retaining valid zero measurements for live nodes. No merge-blocking risk remains.

- Line 149: Update the activeAgents condition in toRelayNode to expose the
measurement only when live is explicitly true and status is not offline, using
live !== true while preserving the existing readNumber behavior. Add a test
covering records with active_agents but no live field, verifying activeAgents
remains undefined.
