Conversation
…ilures and identity takeover The relaycast engine pushes ephemeral `context.update` frames to every ws-kind node, but `ServerToNode` had no variant for them, so every frame failed to parse and was logged as `invalid fleet node ws frame`. Among the events lost that way were the `delivery.failed` / `delivery.deferred` notices the engine sends to the SENDING agent when a recipient could not be reached (relay#1615), and `agent.identity_taken_over`. - fleet_wire: add `ContextUpdate` + `ContextTopic` mirroring the engine's canonical schema, forward-compatible (no `deny_unknown_fields`) like the other inbound frames, plus the canonical fixture and round-trip coverage. - runtime/fleet: route the parsed frame off the existing fleet-control channel. `delivery.failed`/`delivery.deferred` for a hosted agent now emit the same `BrokerEvent::MessageDeliveryFailed` the broker's own dead-letter path uses (engine reason + target agent name) plus an info log; `agent.identity_taken_over` drops the worker's cached Relaycast registration via `forget_agent_registration` so the next operation re-registers instead of first hitting a 401. Everything else is ignored at debug — never as an invalid frame. - RelayFlow proof case 1615-context-update-frames stands up a dependency-free fake Relaycast (HTTP + /v1/node/ws) and observes the exact base/head broker binaries.

… log filter Review follow-up on relay#1615. - runtime/fleet: `delivery.deferred` no longer emits `BrokerEvent::MessageDeliveryFailed`. A deferred delivery stays queued for a later `available_at` retry, so reporting it as a failure invites the sender to resend and duplicate the message the engine still holds. It now takes a log-only path (`log_fleet_delivery_deferral`, info with worker/target/ available_at/reason); only `delivery.failed` is surfaced as an event. - RelayFlow case 1615-context-update-frames: widen `RUST_LOG` so the routed marker survives the filter regardless of which prefix the call site uses. The event's tracing target is its module path (`relay_broker::runtime::fleet`) — `target = "relay_broker::fleet"` in the macro is a structured field, not the metadata target — so the directive now enables both. - Docstrings on the new `context.update` surface (fleet_wire fields and tests, node_control test, runtime helpers). - Trajectory traj_h0xx33q5a1ga: record the commit, the product files it touched, a real start/end trace range, and the verification actually run. - CHANGELOG: the bullet now only claims `delivery.failed` is surfaced.

P3: The summary text now describes delivery.deferred as log-only, but that behavior was introduced by commit e22a7a71 (keep deferred deliveries non-terminal), which is outside the traced range that ends at c919d2ee. The range cited (6d5199ff..c919d2ee) therefore does not span the work the Summary now describes. Regenerate the trajectory summary (via the trail renderer, not a hand edit) so the Commits/traced range extends to the PR head e22a7a71, keeping the metadata consistent with the described behavior.</violation>

…changelog with impact Review follow-up on relay#1615. - runtime/fleet: the `delivery.failed`, `delivery.deferred` and `agent.identity_taken_over` arms of `handle_fleet_context_update` each repeated the same resolve-then-debug-drop guard. Extracted it as `resolve_context_update_workers`, which returns `None` (after logging the shared "no matching worker" debug drop) when this broker hosts none of the addressed agents, so each arm is a single `let Some(workers) = ... else`. Behaviour is identical; `fleet_context_update_workers` stays `pub(super)` because `runtime/tests.rs` exercises it directly. - CHANGELOG: lead the `delivery.failed` bullet with the user-visible impact (a DM to an unreachable agent is no longer silently lost) and demote the frame-parsing fix to the parenthetical it is. - Trajectory traj_h0xx33q5a1ga: extend the record to the review follow-up commit e22a7a7 (commits list, `_trace.endRef`, summary Commits/Traced range). e22a7a7 touched no product file c919d2e had not, so `filesChanged` is unchanged. Hand-edited and re-validated with `agent-trajectories doctor` because `trail` cannot amend a completed trajectory.

Run 33763946847 failed with The Cloud RelayFlow runner has not scheduled any proof run since roughly 14:00 UTC, so a re-run right now would hang for another hour. I will re-run this once a proof run on any relay PR gets past pending, and will note the result here. Generated by Claude Code |

Re-ran the proof once the Cloud queue started scheduling again (attempt 2 of 33763946847, 16:53 UTC). It got through the queue this time but failed before either arm ran: The organization's Daytona CPU/concurrency quota is exhausted, so the per-step sandbox cannot be created; the same error hit #1649's proof at 16:58. Still nothing to do with this PR's diff. Once the quota is freed (stale sandboxes from the earlier stuck runs are the likely culprit), a single re-run of this workflow should pass as it did on 90294ad. Generated by Claude Code |

Summary
The relaycast engine pushes a
context.updateframe to everywsnode for ephemeral events (presence, channel membership, delivery receipts, identity takeover). The broker'sServerToNodeenum had no variant for it, so every such frame failed to parse and was logged asinvalid fleet node ws frame. The broker's own fixture test hard-coded the same five frame types, so the gap was self-consistently untested.This PR:
ServerToNode::ContextUpdate(plus a snake_caseContextTopicenum) infleet_wire.rs, mirroring@relaycast/typesFleetContextUpdateMessageSchema. Notdeny_unknown_fields, matchingDeliver. Copies the engine's canonicalcontext.update.jsonfixture intotests/fixtures/fleet-wire/and adds it to the round-trip test.handle_server_message; theOk(other)arm already carries it) and handles it inruntime/fleet.rs:delivery.failed(topicagent): resolvesagent_idsto locally hosted workers via the authoritativeagent.registerbinding and emits the existingmessage_delivery_failedbroker event for each sending worker (to= the engine's target agent,lastError=relaycast delivery.failed: <reason>,delivery_id/event_idcarried through), plus a structuredinfo!. SDK and dashboard consumers already render that event, so a broker-hosted agent that DMs an unreachable agent now surfaces the failure. Related: /api/send reports Relaycast publication as success without recipient reachability #1615. No PTY injection and no change to/api/send's response shape.delivery.deferred(topicagent): logged at info withavailable_atand the reason, and deliberately emits no event. A deferred delivery stays queued for a later retry, so surfacing it as a terminal failure would invite duplicate resends.agent.identity_taken_over: invalidates the worker's cached agent token viaforget_agent_registration, the same path release uses, so the next operation re-registers instead of first hitting a 401. Structuredwarn!.agent_idsname no worker here: onedebug!, neverwarn, never "invalid".FleetDeliveryBook::active_agent_name()(inverse ofactive_agent_id, authoritative bindings only).Out of scope, deliberately: no
#[serde(other)]catch-all (unknown frame types should still surface), noagent.recover/node.spawn, no heartbeatload_reported, no wire renames.Test Plan
New tests: three
fleet_wireunit tests (fixture parse, nullchannel_id, topic serde), twoFleetDeliveryBook::active_agent_nametests, and runtime tests inruntime/tests.rscovering thedelivery.failedemit, thedelivery.deferredno-event path, theidentity_taken_overtoken invalidation, the ignored-event path, and the no-matching-worker path.The RelayFlow case below was run on both arms against freshly built binaries (base from
origin/main, head from this branch) and produced the declared outcomes.RelayFlow Proof
bugfix1615-context-update-framesThe case stands up a dependency-free fake Relaycast (HTTP routes plus a hand-rolled RFC 6455 node-control server), answers
node.register, pushes exactly onecontext.update(topic: agent,event: delivery.failed), and watches the exact broker binary's stderr: base emitsinvalid fleet node ws frame(context_update_rejected_as_invalid_frame), head routes the frame to the runtime (context_update_accepted_and_routed). The head marker is the routed-and-handled log line rather than themessage_delivery_failedemit, because the emit requires a live spawned worker with an authoritative binding; that path is covered by the runtime unit tests.Note for future readers: the broker's
target = "relay_broker::…"macro arguments are structured fields, not tracing targets (only thetarget:form sets metadata), so the real target of every broker log line is its module path. The case'sRUST_LOGenables both forms.Screenshots
