Cloud dogfood: Run fan-out mode (N Runs at once, timed) - #22344
Conversation
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
run_fanout=N creates N single-variant Runs at once from one smoke account, each a small read-only codex task, follows each to a terminal state and records admission, queue wait, attempt time and the agent's reply. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

There was a problem hiding this comment.
The reply read hides request errors with .catch(() => null). A failed request, a non-200 response, and valid output with no agent message all become agentReply: null. The journey can still report success because it checks only Run outcomes.
Record a separate reply-read status and error for each lane so operators can tell why a reply is missing.
…9 message Review findings on #22344: Run API errors are { error, message }; a lane past the deadline is cancelled so it can't create a VM after the account is deleted; run-time stats cover succeeded lanes only; a cleanup error no longer rewrites the receipt; retention drops to 5 minutes.

-
Explanation
The description provides a detailed summary, testing results, risk assessment, and known limitations. It omits the template's Changelog, Proof, and Checklist sections, but the core information needed for review is present.
Full details: Docstring Coverage
-
Explanation
Docstring coverage is 83.33% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 6 functions across 3 files. (1 skipped: 1 unsupported.)
Full details: Cmux Cloud Persistent Session And Early Input
-
Explanation
PASS. The pull request changes only the Cloud VM dogfood workflow, its Run API fan-out orchestration, and tests. The diff does not add or change
cmux-tui, Ghostty, PTY or shell readiness, terminal attachment, persistent transport, input routing, snapshot refresh, revision fences, leases, or authentication. The/api/vm/{id}/execcall reads retained VM output after a completed Run; it does not create a terminal client or transport per request or event. No condition in the persistent-session and early-input rule is introduced.
Full details: Cmux Swift Actor Isolation
-
Explanation
The pull request changes only YAML, JavaScript, and TypeScript files. The authoritative diff contains no Swift files or Swift production changes, so it does not introduce or worsen Swift 6 actor isolation issues.
Full details: Cmux Browser Automation Off-Main
-
Explanation
The pull request changes only the Cloud VM dogfood workflow and JavaScript fan-out orchestration/tests. It does not change
Sources/TerminalController.swift,ControlCommandExecutionPolicy.swift, browser socket commands, WebKit/AppKit worker routing, or browser policy tests. Therefore, it does not introduce or worsen the specified browser automation off-main violations.
Full details: Cmux Expensive Synchronous Load
-
Explanation
PASS: The pull request changes only GitHub workflow, JavaScript, and TypeScript files. The authoritative diff contains no Swift changes, so it cannot introduce or move an expensive synchronous Swift agent-history load onto an interactive path.
Full details: Cmux Cache Substitution Correctness
-
Explanation
The diff does not substitute a cache for an authoritative read. The new fan-out code reads Run state from
GET /api/runs/:id, derives timings from returned events, and reads agent output from the retained VM. Itssnapshotvariable is an API response, not a cache. The only writes are the workflow result and screen artifacts. No persistence, history, undo, or snapshot consumer trusts a cached value, so the cold-cache and stale-cache conditions do not apply.
Full details: Cmux Algorithmic Complexity
-
Explanation
No algorithmic-complexity failure is introduced. The new production fan-out path accepts at most 32 lanes through
parseRunFanout, while the workflow exposes at most 20. Per-lane polling is independent, and the repeated lane filtering, mapping, and statistics sorting operate on this explicit small bound. The event and JSONL scans are linear within one Run. Existing scans indogfood-journey.mjsare not worsened by the diff.
Full details: Cmux Swift Concurrency
-
Explanation
The pull request changes only one YAML workflow, two JavaScript modules, and one TypeScript test. The reviewed diff contains no Swift files or Swift concurrency changes, so this check is not applicable.
Full details: Cmux Swiftpm Lockfiles
-
Explanation
PASS. The PR changes one GitHub Actions workflow and web JavaScript/TypeScript files only. It does not change any Package.swift, Package.resolved, .gitignore, cmux.xcodeproj package references, or SwiftPM dependency pins. Therefore the SwiftPM lockfile policy is not violated.
Full details: Cmux User-Facing Error Privacy
-
Explanation
PASS. The changed error and receipt data belong to the Cloud VM dogfood GitHub workflow and its developer-only orchestration script. The workflow writes summaries and artifacts for operators; no changed text reaches a cmux app UI, product CLI, or product API response. The captured lane errors are truncated diagnostics, and the tests are explicitly exempt. The provider/configuration terms are therefore within the rule's internal CI and operator-diagnostics allowance.
Full details: Cmux Full Internationalization
-
Explanation
PASS. The diff changes only a GitHub dogfood workflow, cloud-vm operational scripts, and tests. The added English strings are workflow/operator output, CLI diagnostics, and a temporary smoke-run instruction. No Swift text, app catalog, web UI, locale metadata, API response copy, rendered markdown, or
web/messages/entry is changed.
Full details: Cmux Architecture Rethink
-
Explanation
The pull request changes only a GitHub workflow, JavaScript modules, and a TypeScript test. It introduces no Swift architecture changes, so the Swift architectural-rethink failure conditions do not apply.
Full details: Cmux Swift Auxiliary Window Close Shortcuts
-
Explanation
PASS: The pull request changes only a GitHub workflow, JavaScript modules, and a TypeScript test. The authoritative diff contains no Swift, storyboard, or XIB changes, so it does not add or materially change a cmux-owned auxiliary window.
Full details: Cmux Source Artifacts
-
Explanation
The diff adds or updates only intentional source-control content: a workflow configuration, two hand-written fan-out scripts, and a test file. No logs, screenshots, recordings, temp or scratch directories, dependency checkouts, caches, build output, downloads, or copied artifacts appear in the changed paths.
-
Full details: Cmux No Hacky Sleeps
-
Explanation
The new production path adds fixed-delay polling in
web/scripts/cloud-vm/run-fanout.mjs:97-100. Each admitted Run waitspollMs(default 3 seconds) before the nextGET /api/runs/:id, and the production journey passes its realsetTimeout-basedsleepatdogfood-journey.mjs:495-496. This coordinates Run lifecycle completion through elapsed time, without cancellation propagation. The Run service already records terminal events such asattempt.succeeded,attempt.failed, andattempt.cancelled, and exposes them at/api/runs/:id/events; the new code does not use that readiness signal. Deterministic test sleeps do not make the production delay test-only.Resolution
Replace the fixed-delay snapshot polling with a cancellation-aware Run completion mechanism owned by the Run API, such as a long-poll or event stream backed by terminal Run events. Preserve a bounded deadline, propagate cancellation through the wait, and add tests for terminal-event completion, cancellation, and deadline expiry.

Cancel and settle timed-out Runs before account cleanup.
runFanout records "timeout" without cancelling the Run. cleanup() can then delete the account while a worker still provisions or uses a VM. Cancel each non-terminal Run, wait for cancellation to settle, and delete each recorded providerVmId before deleting the account.
The deadline handler also needs access to in-flight Run IDs. Register those IDs when admission succeeds so the handler can cancel them.
Run-provisioned VMs are already included by GET /api/vm; no separate listing workaround is required.

Fence timed-out Runs before account cleanup.
cancelRun marks the Run as cancelled but does not wait for its running attempt. A worker can still be inside POST /api/vm when emptyAccount() lists and deletes the account's VMs. A failed cancellation is also ignored, and the journey deadline path has no access to the in-flight Run IDs.
Do not treat the Run's terminal status as cancellation settlement. Require a successful cancel response, poll fresh snapshots until the attempt is terminal, and read attempts[0].providerVmId from the final snapshot. Track all admitted Run IDs so the journey deadline handler cancels them as well. If cancellation fails or an attempt remains active, do not delete the user; leave cleanup for the existing sweep.

snapshots until the attempt reaches a terminal state; use the final snapshot’s
attempts[0].providerVmId for cleanup. Ensure the journey deadline handler
cancels all tracked Run IDs, and if cancellation fails or any attempt remains
active, skip user deletion so the existing sweep can retry cleanup.

Summary
Leo's goal for the agent lanes is to run them as Cloud Runs instead of local subagents. Nothing in the repo measured fan-out through the Run API, so this adds a
run_fanoutinput (0, 1, 5, 20) to the existing Cloud VM dogfood journey workflow.With
run_fanout=N, the journey signs in its smoke account and creates N single-variant Runs at the same moment throughPOST /api/runs, instead of the TUI journey. Each Run's variant has a real instruction: codex reads README.md and replies with its first line. The receipt records, per Run:rejected)attempt.started) and attempt time, from the Run's own eventsThe job summary prints the outcomes and p50/p90/max of each timing. Cleanup is the journey's: every VM of the smoke account and then the account are deleted.

Adds a
run_fanoutinput to the Cloud VM dogfood workflow so agent lanes can run through the Run API instead of the local TUI journey. It accepts 0–32 runs; the workflow exposes 0, 1, 5, and 20.With
run_fanout=N, the journey signs in with its smoke account and creates N single-variant Runs at once, each running a small codex task (read README.md, reply with its first line). The receipt per Run records admission time and HTTP status (a 429 at the active-VM cap counts as rejected, and the receipt names the cap), queue wait and attempt time from the Run's own events, and the outcome, error, and the agent's last retained message. Lanes still running at the deadline are cancelled so they can't create a VM after the account is deleted; run-time stats cover succeeded lanes only, and a cleanup error no longer rewrites an already-written receipt. The job summary prints outcomes plus p50/p90/max of each timing, and the journey exits non-zero if any lane fails.Not yet exercised: the workflow itself —
cloud-vm-stagingonly deploys from protected branches, so the 5- and 20-Run fan-outs run after merge.run_fanoutdefaults to0, leaving the journey unchanged.Written for commit 11612db. Summary will update on new commits.
