feat(cloud): headless device-link login (agent-relay cloud login --device) - #1435
Conversation
`agent-relay cloud login` was browser-only, so a machine reachable only over ssh could not be provisioned. This left `barry` as the only fleet node unable to push ai-hist history. Copying `cloud-auth.json` from a logged-in machine is not a workaround: refresh tokens rotate against a single server-side session row, so two machines sharing a file silently log each other out within hours. The device flow gives each machine its own session instead. - `agent-relay cloud login --device` prints a short code to approve in a browser on any other device, then polls until approved. - Login falls back to the device flow automatically over ssh, or on a Unix host with no display server, rather than waiting on a loopback callback that can never arrive there. - The poll honours the RFC 8628 backoff contract: it always sleeps a full interval before each request, widens the interval on `slow_down` and on a 429 `Retry-After`, and never narrows it again. Denied, expired, and replayed grants raise distinct errors instead of hanging. - Sessions are written through the existing persistence path, so `cloud session --json --reveal-token` is unchanged afterwards. Headlessness is deliberately not keyed off `CI`: a CI runner has no browser, but it also has no human to approve the code, so routing it to the device flow would hang for the full grant lifetime instead of failing fast. `auth.test.ts` now pins the browser-availability signal so the browser-flow tests do not inherit whether the runner is a headless Linux box. Requires the cloud device authorization endpoints (AgentWorkforce/cloud#2941). Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

| - `agent-relay cloud login --device` authenticates a machine that has no browser, using the OAuth device flow: the CLI prints a short code, you approve it in a browser on any other device, and the headless machine writes its own `cloud-auth.json`. Login now falls back to this automatically over SSH or on a Unix host with no display server, instead of waiting on a loopback callback that can never arrive. Each machine gets its own cloud session, so copying `cloud-auth.json` between hosts — which silently logs them out of each other as refresh tokens rotate — is no longer necessary. Requires cloud with the device authorization endpoints. |

Condense the changelog entry to the shipped impact
The new entry is a four-sentence implementation narrative, including refresh-token backstory and a deployment dependency, whereas the repository requires a concise, impact-first bullet and explicitly asks contributors to drop implementation backstory. Reduce this to a short statement naming cloud login --device, the automatic headless fallback, and their practical effect.

Retry transient device-token polling failures
When a token poll encounters a transient connection timeout or reset, this catch immediately abandons the still-valid grant, so even an approval completed by the user is lost and the entire login must be restarted. RFC 8628 §3.5 requires connection timeouts to reduce polling frequency with backoff; keep polling with a widened interval until the grant deadline rather than treating the first transport failure as terminal.

Preserve the widened polling interval after a 429
If an earlier slow_down has widened the interval to 30 seconds and a later 429 carries Retry-After: 10, this assignment narrows the next wait to 10 seconds. That violates the device-flow requirement that a slow_down increase apply to all subsequent requests and can cause repeated rate limiting; use the maximum of the current interval and the parsed retry delay.

…orting The server half of this flow (AgentWorkforce/cloud#2941) wraps claiming the grant and minting the session in one transaction: if issuance fails, the claim rolls back, the grant stays `approved` and claimable, and the endpoint answers 503 `server_error` rather than burning the approval. That exists specifically so the client can poll again and still succeed. This client did not. `server_error` fell through to the default branch and became fatal, so a momentary blip discarded an approval the human had already given and made them redo the whole flow — the exact harm the server-side fix was written to prevent. The two halves did not compose. Any 5xx is now retried with a widened interval, bounded by the grant deadline, so a gateway 502 with an HTML body recovers too while an outage that outlasts the grant still ends the loop. Backing off rather than retrying at pace avoids hammering a server that is already failing. Each of the three new tests was confirmed red against the parent (`Device login failed: server_error`) before the fix. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

So a momentary DB blip during the minting poll discarded an approval the human had already given and made them redo the entire flow — precisely the harm the server-side transaction was written to prevent. The server stopped burning the approval; the client threw it away instead. Worth being direct about: I introduced the 503 path in cloud#2941 and did not check the client against it. The server test suite proved the grant survives; nothing proved anyone could use the surviving grant. That gap only shows up when you read both repos against each other. The CLI's own suite had no 5xx case at all, which is why green CI on both sides said nothing about it. FixAny 5xx is retried with a widened interval, bounded by the existing grant deadline:

Holding merge — the Major finding is live at head, and it is the one that matters most for this feature's actual purpose. CodeRabbit commented at 1. MAJOR — no request timeout on the device-flow fetches.
This is not a generic robustness nit — it defeats the point of the feature. The whole reason this exists is barry: a headless box reached over ssh, where nobody is watching a terminal. A silent indefinite hang there is strictly worse than a failure, because a failure is visible. Add a bounded timeout to both the start call and each poll request, and surface a clear error on expiry. 2. Minor —
3. Minor — the CI assertions do not cover the case the comment warns about. Both cases pin a browser signal ( What is good: all checks green including E2E Integration Test, CodeQL and Dependency Review; you self-unblocked the Fix 1 and 2, decide on 3 explicitly. Then the acceptance test I actually want: barry, over ssh, no browser, authenticates and starts pushing. |
…ntly Node's `fetch` has no default timeout. Neither the start request nor any poll passed a signal, so a stalled TCP connection never settled and `agent-relay cloud login --device` hung with no output and no error. That is the one failure this feature cannot have. It exists for a headless box reached over ssh, where nobody is watching a terminal — a silent indefinite hang there is strictly worse than a failure, because a failure is visible. And the start request stalls before anything has been printed, so the user sees a bare cursor forever. Both legs now carry an abort budget (30s by default, injectable for tests): - The start request fails with "Timed out after 30s trying to reach <url>", as a CloudAuthError callers can already branch on. - Each poll is bounded by whichever is sooner, the request budget or the grant deadline, so a stalled socket can never outlive the grant it is waiting on and skip the loop's own expiry check. - A stalled poll is treated like the transient 5xx handled in the parent commit: back off and retry rather than discard an approval the human may already have given, and say so on stdout so a slow network does not look like a hang. Stalls that outlast the grant still end with the expiry error, not an infinite loop. All five new tests were confirmed red against the parent — three of them by hanging until the test timeout, which is the bug itself. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`method` was computed before the already-logged-in short-circuit, and the `finally` block emitted `cloud_auth` with it regardless. A no-op invocation — live session, no `--force`, `ensureAuthenticated` never called — therefore reported `method: 'device'` or `'browser'` as though a flow had run. The whole point of the field is measuring headless adoption, so this inflates exactly the number it exists to produce, on the invocations that are cheapest to repeat. And it is the class of telemetry that later gets trusted. `method` is now assigned immediately before `ensureAuthenticated` and omitted from the event when it is still undefined, so the no-op path records the login attempt without claiming a style for it. Three CLI tests cover it; the omission case was confirmed red against the parent. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The two `CI` assertions each pinned a browser signal — first a `DISPLAY`,
then a platform that always has `open`. A typical Linux runner has neither,
so `isHeadlessEnvironment({ CI: 'true' }, 'linux')` returns true and selects
the device flow, and that branch was the untested one in a headless-login
feature.
Pin it. `CI` never suppresses headless detection; it simply is not a signal
on its own, and the absent display is what decides. The behaviour is right
as it stands: unattended runs never reach this code, because a
non-interactive `ensureCloudSession` throws "login required" before any flow
is chosen, so only an explicit `cloud login` on a runner lands here — and
there the device flow is the only one that can work.

…imits Follow-up on the two P2s cubic raised against the timeout commit. Both are real, and both turn the timeout budget back into the failure it was added to prevent. `AbortSignal.timeout` throws a RangeError on a fractional delay and silently collapses anything past the 32-bit timer range to 1ms — an immediate abort. The fractional case does not need a careless caller to reach: the poll budget is derived from the grant deadline, which is derived from the server's `expires_in`, so a non-integer `expires_in` is enough. And because the signal is constructed inside the fetch call, the RangeError was caught by the connection handler and misreported as "Could not reach <url>" — a wrong diagnosis of a bug in our own arithmetic. Delays are now floored and clamped to [1, 2^31-1] before they reach a timer. Separately, the poll slept a full widened interval before re-checking the deadline, so a 60s backoff with 5s of grant left sat on the expiry report for most of a minute. Every retry path widens the interval, so this was reachable from `slow_down`, from a transient 5xx, and from the new stall retry. The wait is now capped at the remaining grant lifetime, which makes expiry land on time rather than a backoff step late — the same "looks like a hang" failure the request timeouts address, one level up. Three tests, each confirmed red against b8200a5. The sleep-cap test needed a 25s grant to discriminate: against 30s the 5/10/15 backoff lands exactly on the deadline and passes either way.

Retracting my earlier assessment — I said this was clean, and it is not. A P1 is live at head. I verified five findings and reported the PR verified.

Unchanged and still good: all checks SUCCESS, the fetch timeouts, the Report the status of every finding, not just the ones you fixed. "Addressed" and "not applicable because X" are both fine answers; silence is not. |
`authorizedApiFetch` called `loginWithBrowser` directly when a 401 could not be refreshed, bypassing the `loginInteractive` selector that `ensureCloudSession` uses. A headless machine could therefore complete the device flow once and then hang on its first re-auth, waiting on a loopback callback it has no way to complete — the feature failed exactly in the steady state it exists for. Route that fallback through `loginInteractive`. `authorizedApiFetch` gains optional `device` and `env` options; nothing mid-request carries an explicit `--device`, so left unset the selector still auto-detects a headless host, which is the behaviour that matters here. Also condenses the device-login changelog entry per review. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

P1 fixed — and it introduced two new findings, both live at head The P1 fix is right, and the comment you left explaining why the selector must be shared is exactly the kind of note that stops someone re-breaking it later. Confirmed at line 847: But cubic reviewed the fix at P2 — P3 — CI is green at head. Everything previously verified still holds. For the record, this PR has now had 14 review comments across three bots over four fix cycles, and each fix has surfaced the next finding in the same neighbourhood — timeouts, then timer clamping, then deadline capping, then the selector, now cancellation. That is a sign the review is working, not that the work is bad. |
Routing re-auth through the device flow made cancellation matter more than it did under the browser flow: the device grant blocks for its full lifetime, so an aborted request that fell through to a login left a cancelled CLI or workflow waiting on authorization nobody asked for. Check init.signal?.aborted before loginInteractive and surface signal.reason, matching the abort idiom already used for the auth lock. Also restore vi.spyOn spies in an afterEach: clearAllMocks resets call history but leaves spies installed, so a test failing mid-body silenced console.log for every later test in the file - exactly when a failure needs the output.

cloud-auth.jsonfrom a logged-in machine is not a stopgap but a latent outage: refresh tokens rotate against a single server-side session row, so whichever machine refreshes first invalidates the other. The device flow gives each machine its own session.What
