-
Explanation
The description clearly explains the durable Runs feature, dogfood behavior, validation performed, and remaining deployment-dependent verification. It uses different headings from the template and omits explicit Changelog, Proof, and Checklist sections, but the core required information is present.
Full details: Cmux Cloud Persistent Session And Early Input
-
Explanation
The diff does not add manual renderers, Ghostty runtime admission, or persistent transport code. The dogfood keeps one long-running
cmux-tuilink process and changes only its route; new links occur after deliberate link loss or client relaunch, which the rule permits. The worker reuses one authenticated Cloud client per claim for multiple VM operations, while Run routes retain auth, team scope, idempotency, ticket, and lease fences. No explicit failure condition is introduced.
Full details: Cmux Swift Actor Isolation
-
Explanation
The reviewed diff contains no Swift, Xcode project, or Swift workspace files. All changed paths are TypeScript, JavaScript, SQL, JSON, YAML, or configuration files, so this check's Swift actor-isolation failure conditions are not applicable.
Full details: Cmux Browser Automation Off-Main
-
Explanation
PASS. The pull request changes only web, workflow, database, and JavaScript/TypeScript run-control files. The authoritative diff contains no
Sources/TerminalController.swift,ControlCommandExecutionPolicy.swift, or browser socket automation commands. It does not introduce or worsen the WebKit/AppKit worker-lane conditions in the rule.
Full details: Cmux Expensive Synchronous Load
-
Explanation
The pull request changes only TypeScript, JavaScript, SQL, JSON, and YAML files. It contains no Swift changes, so it cannot add or move an expensive synchronous Swift agent-history load onto the main actor or an interactive path.
Full details: Cmux Cache Substitution Correctness
-
Explanation
The diff does not replace an authoritative read with a cache. Run snapshots and receipts read current rows from PostgreSQL through
readRunSnapshotandlistRunSnapshots, including runs, attempts, events, and artifacts. Theafter()queue trigger is documented as a latency optimization, not as a data source; the durable queue and cron provide recovery. No cached value appears in a persistence, history, undo, or snapshot path.
Full details: Cmux Swift `@Concurrent`
-
Explanation
The pull request changes TypeScript, JavaScript, SQL, JSON, YAML, and test files only. The authoritative diff contains no Swift files or Swift declarations, so the Swift
@concurrentcheck is not applicable.
Full details: Cmux Swiftpm Lockfiles
-
Explanation
PASS: The PR changes one workflow, but it does not change SwiftPM packages, Xcode package references,
.gitignorerules, or dependency pins. The changed workflow only adjusts scheduling and dogfood defaults, so the SwiftPM lockfile conditions do not apply.
Full details: Cmux Swift Logging
-
Explanation
PASS. The reviewed diff contains no Swift, Objective-C, or Objective-C++ files. The changed files are TypeScript, JavaScript, SQL, JSON, YAML, and tests. Therefore, the Swift logging rule has no applicable changed code.
Full details: Cmux User-Facing Error Privacy
-
Explanation
No concrete cmux end-user path is present for the changed Run messages. The only in-repository caller is the managed dogfood workflow, which writes results to GitHub Actions summaries and artifacts and is an operator diagnostic surface. The Run HTTP wrapper returns generic text for unexpected provider or database failures; the provider-specific validation text is not shown by an app UI or product CLI in this repository. The changed API routes alone do not establish end-user scope under the rule.
Full details: Cmux Swiftui State Layout
-
Explanation
PASS. The pull request changes only web TypeScript/JavaScript, SQL, JSON, YAML, and test files. The authoritative diff contains no Swift or SwiftUI files, so the SwiftUI state-layout failure conditions do not apply.
Full details: Cmux Swift Auxiliary Window Close Shortcuts
-
Explanation
PASS. The pull request changes no Swift files. The custom check applies only to Swift changes that add or materially change standalone cmux-owned windows, so the auxiliary-window close-shortcut rule is not applicable.
Full details: Cmux Source Artifacts
-
Explanation
All 28 changed paths are source, tests, migration/schema, workflow, deployment configuration, or the intentional
.cmux/setup.jsonproduct manifest. The diff adds no artifact directory, logs, screenshots, recordings, cache, checkout, build output, or package download. Runtime/tmppaths and runner temporary output are code behavior, not checked-in artifact paths.
Full details: Cmux No Test Or Debug Seam In Production Source
-
Explanation
The pull request changes no Swift files under any production
Sources/path. All changed files are web TypeScript/JavaScript, SQL, JSON, or workflow files, so the specified production Swift seam check is not applicable.
-
Full details: Cmux No Hacky Sleeps

The PR adds production timing coordination in two places.
web/scripts/cloud-vm/dogfood-journey.mjs:132-149pollsGET /api/runs/:idand sleeps 250–5000 ms until completion.web/services/runs/runner.ts:82-86adds a raw 20-secondsetIntervalto renew worker leases. These hide run-readiness and lease-lifecycle state behind elapsed wall-clock time. The existing dogfood delays are not needed for this finding.Resolution
Replace
waitForRunpolling with a completion event or other owner-provided run state transition, with a bounded cancellation-aware timeout. Replace the raw lease-renewal interval with a dedicated cancellation-aware lease scheduler owned by the worker lifecycle, and add tests for cancellation, lease expiry, and renewal failure.
Full details: Cmux Algorithmic Complexity
-
Explanation
New production code in
web/services/runs/worker.ts:345-377performs a per-target rescan.reconcileCancelledRunAttemptsloops up to 500 times, and each iteration runs a fresh orderedSELECT ... LIMIT 1overrun_attemptsbefore updating one attempt. This gives batch cancellation recovery repeated collection scans instead of a one-pass batch plan. The cron worker invokes this path fromweb/services/runs/runner.ts:114.Resolution
Replace the loop with one bounded database batch using a CTE and
FOR UPDATE SKIP LOCKED, update all selected attempts in one statement, and insert cancellation events as a grouped batch. Add an index covering the cancellation predicate and ordering if query planning requires it. Preserve the existing run-lock fencing semantics.
Full details: Cmux Full Internationalization
-
Explanation
The PR adds literal English API response copy without a locale-specific source. Examples include messages in
web/app/api/runs/route.ts, the attach-ticket and promote routes,web/app/api/runs/[id]/events/route.ts,web/services/runs/http.ts,attach.ts, andpromotion.ts. These messages are returned throughRunHttpErroror stored in Run receipts. Noweb/messages/file changed, whileweb/i18n/routing.tslists 20 supported locales.Resolution
Replace user-facing API and Run receipt messages with stable localized message keys resolved through
next-intlor another locale-aware source. Add matching translated entries to every locale inweb/i18n/routing.ts:en,ja,zh-CN,zh-TW,ko,de,es,fr,it,da,pl,ru,bs,ar,no,pt-BR,th,tr,km, anduk. Keep machine error codes and protocol tokens literal, but do not use literal English for response or persisted user-facing copy.

retainMs: 20 * 60_000 exceeds the new spec maximum, so POST /api/runs returns 400.
normalizeResources in web/services/runs/spec.ts Line 160 now caps resources.retainMs at 900,000. This value is 1,200,000. integer() throws RunSpecValidationError, and the route returns 400 run_invalid_spec. Every dogfood journey fails at runCreate, including the new daily schedule.

Add clock-skew margin before the first expiration redemption.
runAttachTicket calculates expiresAt with the application server's Date.now(), but redemption compares it with PostgreSQL's now(). The current 1,200 ms wait leaves only about 200 ms of margin, so clock skew can make the check intermittently return success.
Wait until the TTL plus the supported clock-skew margin before the first redemption. Do not poll this redemption call: a successful redemption sets redeemedAt, so a later 410 would only prove single-use, not expiration.

🚀 Performance & Scalability | 🔵 Trivial | 🏗️ Heavy lift
Load list snapshots in batched queries instead of one snapshot per run.
listRunSnapshots returns up to 50 run IDs. It then calls readRunSnapshot for each ID. Each call runs one scoped run query and three child queries, so one GET /api/runs costs about 201 database round trips. Each snapshot also loads up to 1,000 events. In the worst case, one list response serializes about 50,000 event rows.
Load attempts, events, and artifacts with inArray(runId, ids) in three queries, then group the rows by runId. Cap or omit events in the list view. Clients can page events through /api/runs/:id/events.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
The instruction text can end the CMUX_RUN_SCRIPT heredoc early.
instruction is user input of up to 16,000 bytes, and it can contain newlines. quote() protects single quotes only. replaySafeGuestCommand embeds the script in a <<'CMUX_RUN_SCRIPT' heredoc. If the instruction contains a line that is exactly CMUX_RUN_SCRIPT, the heredoc ends at that line. The outer bash -c then runs the remaining instruction lines as shell commands. Those commands run outside the receipt.tmp redirect and outside the started/completed replay protocol.
Encode the instruction so that no instruction line can match a delimiter.

Handle pre-execution failures in processClaim.
processRunQueue calls processClaim directly. It does not pass processClaim to runOneRunAttempt, so the helper's error handler does not protect this path.
The owner check and runCloudClient call occur before processClaim's try block. Their errors can leave the attempt in running without a failed transition. The expired attempt is then eligible for reclamation, so a persistent failure can repeat and prevent completion. The rejection also skips the second cleanupRunMachines() call.
Move both statements into the try block.
🐛 Proposed fix
async function processClaim(attempt: ClaimedRunAttempt): Promise<string> {
- if (!attempt.ownerTeamId) throw new Error("Queued Run lacks an immutable owner");
- const client = await runCloudClient(attempt.userId, attempt.ownerTeamId);
let lost = false;
let renewing = false;

Move the ownerTeamId validation and runCloudClient call into the try block in
processClaim, before executeClaim, so their failures follow the existing error
handling and cleanup path.

Do not emit an artifact URI without a matching route.
runReceipt emits /api/runs/${run.id}/artifacts/${artifact.id}, but the PR adds no matching artifact route. A client that follows this URI can receive a 404. Add the route, or omit uri until the route exists.

Review comment at @web/services/runs/view.ts at line 13:
Update runReceipt’s artifact mapping to omit the uri field until a matching
artifact route exists, so it does not emit a URL clients cannot follow.

Merge receipt for |
…cx-q1lnl) 134 main commits since the last sync (3e7ed5a). Full rename detection (merge.renameLimit=100000). manaflow-ai#21310 (0d5316d, export npm_config_prefix) is now on main; it is a superset of feat's manaflow-ai#21311 copy, so the resume workflows keep one version (main's). No Swift, Rust, Go or package manifest change survives the merge (daemon/remote/go.mod unchanged). Conflict choices: - 209 modify/delete and 1 rename/delete in the legacy app, legacy CLI, cmuxTests, legacy Swift packages and Resources/Localizable.xcstrings: kept deleted. - cmux.xcodeproj/project.pbxproj, cmux.xcworkspace/contents.xcworkspacedata, docs/cli-contract.md, tests/test-execution.toml: feat-cmux-next's side. - ci-macos.yml, seed-derived-data.yml, restore-app-host-test-product.sh, package-test-lane.sh (CmuxTextActions), tests/test_ci_change_areas.py (app-host admission block): feat's side; main's rsync --no-times edits are for CmuxAgentJournal framework staging that feat deleted. Main's new merge-gate change-area test merged in. - scripts/ci/compile-app-host-test-product.sh: main's logic (the legacy cmux target builds without the compilation cache on every Xcode); the test (test_ci_test_compilation_cache_seed.sh) keeps feat's one-scheme checks with main's every-Xcode loop. - nightly.yml and tests/test_nightly_universal_build.sh: feat's side (feat already had manaflow-ai#21761's empty DerivedData start via manaflow-ai#21762, plus the nightly-next build-state prepare and its no-replay check; manaflow-ai#21544's promotion change was already on feat via manaflow-ai#21533). Feat's WRITER gate, live HOLD read, recovery guard, legacy-identity split, Mach-O floor, macOS 15 launch job and bash 3.2 parse hardening kept. - scripts/gh-merge-green: main's version (multiple freeze tokens manaflow-ai#21584, merge-tree merged head manaflow-ai#21576, missing Swift path refusal manaflow-ai#21560, risk evidence manaflow-ai#21692) plus feat's "cmux-next Swift canary" required check, freeze expiry and owner/pr/head metadata, and the canonical merged path. - scripts/install-cmux-tui-client.sh: union of the header comments (main's total download budget manaflow-ai#16305 and feat's attestation retry text). - web/data/cmux-shortcuts.ts: feat's generated table. - web/services/vms/workflows.ts: feat's doc comment on requireUserVm. - Run API: feat's version (manaflow-ai#21337, open lanes manaflow-ai#21634/manaflow-ai#21305 build on it). web/services/runs/*, web/app/api/runs/*, web/db/schema.ts run tables: feat's side.

What changed
Adds the first production slice of the Cloud Run control plane: durable team-scoped Runs and attempts, fenced worker leases, cancellation and replay-safe checkpoints, exact source/setup receipts, attach tickets, event/artifact replay, retained VM promotion, and a protected cron recovery path.
The managed dogfood now creates an asynchronous Run, polls its durable receipt, verifies the exact GitHub commit and
.cmux/setup.jsondigest, reuses the retained Freestyle VM for the terminal journey, checks attach-ticket expiry and single-use redemption, exercises promotion, and records cleanup. A daily staging-only dogfood schedule is included; Huge Blue remains fail-closed.Validation
bun run typecheckbun run lint:complexityactionlint .github/workflows/cloud-vm-dogfood.ymlThe actual Freestyle dogfood requires deployment of this exact head; the workflow is ready to run against staging after the PR is deployed.
