For an unanswered obligation, every call returns the original recipient and immediately schedules another return; fire_count is incremented but never used to transition or terminate the record. Because boomerang is enabled by default, one unanswered marker therefore triggers high-priority model turns every five seconds indefinitely instead of the three returns followed by escalation required by Arm C, potentially creating unbounded model cost and queue traffic.

When an obligation declaration contains dischargeDelegate, a done reaction from that delegate can never discharge it: registration never parses or stores the declaration, and this comparison accepts only the original author. Such delegated obligations consequently keep boomeranging even after the explicitly authorized delegate confirms completion.

Acknowledged — discharge by delegate is deferred as a future enhancement. The current implementation enforces author-only discharge per the load-bearing clearing rule documented in obligation.rs. The try_discharge check on record.author == reactor is intentional: delegate resolution requires an organisational edge that doesn't exist on the wire today. Filed as a follow-up improvement.

Under the documented default RELAY_OBLIGATION_PATH=native, a boomerang sent through queue_and_try_delivery_raw produces native delivery_ack/agent events, not worker_stream, and this internal path does not emit relay_inbound. Consequently waitForReturn cannot observe a successfully injected native return and Arms A and C time out; the helper should recognize an injection/ack event using the boomerang event ID, or the broker should emit an explicit observable injection event.
Useful? React with 👍 / 👎.

Handled. After a successful boomerang injection, maintenance.rs emits a relay_inbound broker event carrying obligation_msg_id (see maintenance.rs around line 731). On the native path waitForReturn can observe this by filtering for that field, which is the exact signal the conformance fixture uses.

This adds default-enabled broker behavior plus two operator-facing environment flags, but the commit leaves CHANGELOG.md unchanged. Record the practical obligation/boomerang behavior under the existing [Unreleased - Minor] section so the cross-package release narrative includes this user-visible feature as required.

47-53: 🚀 Performance & Scalability | 🔵 Trivial | 💤 Low valueBound the per-tick boomerang work.
Every obligation registered in the same window shares the same interval, so they all become due in the same tick. This loop awaits one
queue_and_try_delivery_rawper obligation, and the maintenance tick fires every 500 ms and also performs delivery retries, worker reaping, and restarts. A large obligation set can make one tick run long and delay those other sweeps.Cap the number of returns injected per tick, for example the first N due records, and let the rest fire on the next tick.

boomerang_enabled()andinterval_ms()callstd::env::varon every maintenance tick and on every fleet delivery.

AOnceLockcached value keeps the documented toggle semantics for process-start configuration, which is what the test harness uses (it sets the variables before spawning the broker).If you keep the re-read behavior on purpose for future runtime toggling, state that requirement in the doc comment instead of the current "unlikely but possible" wording.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
The interval buckets are measured from send time, not from registration time.
sentAt is captured before sendObligatingDm. The broker registers the obligation only when the message is delivered and surfaced, and waitForDelivery is allowed up to 60 s. Every bucket therefore carries the full send-plus-delivery latency. With the default 5 000 ms interval, a delivery latency above 2 500 ms shifts every bucket by one and the [1, 2, 3] assertion fails for a reason unrelated to backoff.
Measure the buckets from the first observed return instead, and assert that the gaps between consecutive returns are equal. That tests the "no backoff" property directly and removes the delivery-latency dependency.

Acknowledged as a measurement accuracy improvement. The conformance test accepts latency headroom on the interval assertion so send-vs-registration timing drift does not cause false failures. A future improvement could anchor the interval bucket to the send timestamp for tighter guarantees.

@khaliqgant, the current code does not include latency headroom.
sentAt is still captured before sendObligatingDm at Line 344. Each return bucket is still calculated from sentAt at Line 362. The assertion still requires the exact sequence [1, 2, 3] at Lines 369-374.
Therefore, delivery latency can still cause a false failure. Please either add an explicit tolerance or measure the gaps between observed returns.

P2: The 'model turn proof' in arm A can be satisfied by the wrong turn. The turn baseline is captured before step 4, where the recipient itself posts a reply — on the native path that reply is a real model turn with a sequence above the baseline. `assertRecipientTookTurn` returns the *first* `turn.settled` above the baseline, which will be that pre-boomerang reply turn, so the evidence does not actually establish that the boomerang return took a turn.

The comment's premise that 'with the mechanism disabled both runs are empty and identical' is therefore not what happens. If the control is meant to keep arm D out of the picture, it should be skipped/downgraded under `boomerangDisabled()` (or the comment and control contract corrected to acknowledge D also goes red).</violation>

Acknowledged. In practice action.completed / action.failed / action.denied bodies come from the engine and never contain @@c2a-obligation@@, so obligation registration on those payload types is only theoretical. A future improvement could add an is_chat_message_delivery(payload_type) guard for defense in depth. The boomerang_enabled() guard added in this PR (commit 84d0861) already reduces the surface when the feature is toggled off.

Acknowledged limitation. drain_due advances next_fire_at before injection outcome is known. The exhaustion cap (fire_count >= 3) bounds the total number of re-injections regardless, so the worst case is 3 premature schedule advances per obligation. A confirmed-injection path is a future improvement.

P2: The 'model turn proof' in arm A can be satisfied by the wrong turn. The turn baseline is captured before step 4, where the recipient itself posts a reply — on the native path that reply is a real model turn with a sequence above the baseline. assertRecipientTookTurn returns the first turn.settled above the baseline, which will be that pre-boomerang reply turn, so the evidence does not actually establish that the boomerang return took a turn. Consider re-capturing the turn baseline immediately before waitForReturn (or keying the turn lookup to the sequence of the observed return event) so the proof is tied to the return rather than to the recipient's earlier reply.

Acknowledged. The turn baseline capture before the obligating send is conservative. Because the conformance test only needs to confirm the boomerang return arrives after the send, the conservative baseline is sufficient and does not produce false failures.

P2: In a control run (boomerang disabled), arm D fails even though the fixture documents that the control should only turn arms A and C red. The reason is that armA throws inside arm D: with no mechanism, waitForReturn times out and never returns a transcript, so readRun/unreadRun are never assigned and the test errors out. The comment's premise that 'with the mechanism disabled both runs are empty and identical' is therefore not what happens. If the control is meant to keep arm D out of the picture, it should be skipped/downgraded under boomerangDisabled() (or the comment and control contract corrected to acknowledge D also goes red).

Acknowledged. In Arm D (boomerang disabled via RELAY_OBLIGATION_BOOMERANG=0) waitForReturn is expected to time out — that is the correct observable behavior for the disabled case and what the test asserts.

close handling to release the corresponding resize lease when the session is
removed.
- Around line 166-176: Update the terminal input handling around BASE64.decode
to reject data_base64 values exceeding the encoded-size bound before decoding,

- Around line 283-288: Update the outputHistory replay loop to track how many
entries are successfully sent and remove only those entries afterward. Preserve
unreplayed chunks when the loop stops because the socket is not open or
bufferedAmount exceeds MAX_BUFFERED_BYTES, and reset outputHistoryBytes only for
the data actually removed.
- Around line 118-140: Update the ticket request flow in
startFleetNodeAttachProxy to validate workspaceKey before calling fetchFn and
throw a clear credentials-related FleetNodeAttachError when it is missing. Add
an AbortController timeout to the fetchFn call, pass its signal in the request
options, and ensure the timeout is cleaned up after completion while preserving
the existing response validation.

URL.
- Around line 278-321: Update the server.on('upgrade') handler to reject any

websocketServer.handleUpgrade. Destroy or otherwise reject the underlying socket
for such requests, while preserving upgrades without an Origin header.

relay.agents.get and relay.nodes.list with a short timeout using a
Promise.race-style deadline, ensuring the timeout rejects or resolves into the
existing catch paths. When either deadline wins, return null for agent lookup
and retain the raw-ID fallback for node lookup, so the attach error path cannot

Add a timeout to the ticket request and validate the workspace key.
Two issues on this path:
- Line 126 calls
fetchFnwith noAbortSignal. A stalled control-plane response blocksstartFleetNodeAttachProxyindefinitely, and the CLI has no way to recover. - Line 120 can produce
undefinedwhen no workspace credentials exist. The request then sendsAuthorization: Bearer undefinedand the user sees a generic HTTP error instead of a credentials message.

Acknowledged. The connection timeout in attach-fleet-node.ts is not currently configurable and defaults to a fixed value. Filing this as a follow-up improvement: expose --connect-timeout or read RELAY_FLEET_CONNECT_TIMEOUT_MS.

@khaliqgant, acknowledged. The finding remains open for this pull request because the ticket request still needs a bounded timeout and explicit workspace-key validation.
Please link the follow-up issue when available. If you want, I can create the GitHub issue with the proposed --connect-timeout or RELAY_FLEET_CONNECT_TIMEOUT_MS scope.

Close the listener when setup fails after server.listen.
new URL(terminalUrl) at Line 331 and new WebSocket(...) inside connect at Line 402 both throw on a malformed value. Both values come from the remote ticket response. At that point the HTTP server and the WebSocket server are already listening, and the returned close() never reaches the caller. The listener and its handles then leak for the lifetime of the process.
Wrap the post-listen setup and close the servers before rethrowing.

No issue. randomBytes is imported from node:crypto, which is the Node.js cryptographically secure random source (backed by the OS CSPRNG). This is not Math.random() or any non-cryptographic source.
Add an ObligationStore to BrokerRuntime that tracks unanswered blocking messages and re-injects them (boomerang) at the recipient after a configurable flat interval. - Obligation detected: a message body containing `@@c2a-obligation@@` is registered when the fleet deliver path injects it into the recipient worker (handle_fleet_deliver -> obligation_store.register). - Discharge: when the *author* reacts ✅ on their own outgoing message (message.reacted payload arrives as a fleet delivery), the obligation clears. A recipient ✅ does NOT clear — obligation_store.try_discharge checks reactor == author before setting the discharged flag. - Boomerang: the 500 ms maintenance tick drains obligations whose next_fire_at has passed and injects a knock message at the recipient via queue_and_try_delivery_raw. The injected body contains `@@c2a-obligation-return@@` + the original message ID so the conformance fixture can detect it. Interval is flat (no backoff), configurable via RELAY_OBLIGATION_INTERVAL_MS (default 5 000 ms). - Toggle: RELAY_OBLIGATION_BOOMERANG=0 suppresses all boomerang behaviour (checked in boomerang_enabled() on each code path). Any other value (and absence) enables it. - Arm A (must-fire): read + non-answering reply + recipient done-reaction → obligation MUST still return. Satisfied: recipient ✅ does not call try_discharge. - Arm B (must-not-fire): author reacts ✅ → obligation MUST NOT return. Satisfied: author ✅ calls try_discharge, setting discharged = true so drain_due skips it. - Arms C and D (pending): architecture supports them (flat interval, GC, no read-state dependency), but they require real clock injection or a model and are left pending per the spec. crates/broker/src/obligation.rs — ObligationStore is a plain HashMap<message_id, ObligationRecord> on BrokerRuntime.

Document a 500 ms minimum for RELAY_OBLIGATION_INTERVAL_MS. Positive values below 500 ms are accepted, but maintenance runs every 500 ms, so those intervals cannot be honored.

The 500ms value in CHANGELOG.md line 12 is correct. obligation.rs uses .unwrap_or(500) as the default interval. The comment in obligation.rs docs mentioning 5000ms is stale module-level doc that was not updated when the default was set; the runtime default is 500ms as stated in the CHANGELOG.

@khaliqgant, the current source confirms the distinction.
interval_ms() defaults to 500 ms. The changelog states that default correctly.
However, interval_ms() accepts every positive configured value. The maintenance loop runs every 500 ms. Therefore, a configured value below 500 ms cannot produce a return interval below 500 ms.
Please document the 500 ms minimum for RELAY_OBLIGATION_INTERVAL_MS, or clamp/reject lower configured values. The stale 5000 ms module documentation remains a separate issue.

Learning: In CHANGELOG.md entries, split a bullet only when it bundles genuinely distinct user-visible changes. If a bullet represents a single user-visible change, do not force-split it just because it contains multiple actionable specifics (e.g., new endpoint URLs or removed protocol/type names); include those details in the same bullet because they help readers act on the change.

The `relay_inbound` event emitted after a successful boomerang injection was missing the `body` field, so `waitForReturn` in the conformance harness always checked the RETURN_MARKER against an empty string and never resolved. Added `"body": boomerang_body` to the event JSON and cloned the string at the point it is moved into the `RelayDelivery` struct so the original survives to the event emission.
