Require a terminal XCTest completion signal.
Line 24 accepts a partial batch when it contains one prior summary with 0 unexpected. For example, Executed 2 tests, with 0 failures (0 unexpected) followed by an app-host crash returns success. The workflow then tolerates exit code 65 and masks the crash.
Require the final XCTest completion record before returning success. Add a regression input that contains a zero-unexpected summary followed by a crash marker.

Classifier misses skipped-test summaries
High Severity
SUMMARY_RE only matches the no-skip XCTest line and misses the common with N tests skipped and ... failures form. Suites that skip via XCTSkip then drop out of the all-summary sum, so an unexpected failure on a skipped suite can be ignored when another suite reports 0 unexpected.

…ectation `runCoderouterCLI(waitForSocket: false)` still asked `startMockServer` for a case-bound `expectation(description: "cli mock socket handled")` and then never waited on it. The shared accept loop fulfills that expectation when the listener closes at the end of the helper, so XCTest ended `testCoderouterUnknownVerbStillPassesThroughToTheInstalledCLI` and `testCoderouterClaudeAddOAuthTokenRejectsAPIKeyShapeBeforeTheSocket` with "Failed due to unwaited expectation", which it counts as an *unexpected* failure. Since #12207 the app-host batch classifier fails a batch on any unexpected failure, so this one test turned shard 5 (and the sibling test shard 6) red on main and on every PR: run 34401456032, main run 34342638735 attempts 1 and 2. Serve those two tests from the detached mock server instead, which owns no expectation, and keep the waited path for every other Coderouter test.

…issions guard, screenshot decoupling, notarization hardening) (#12157) * ci: guard reusable-workflow permission grants (red on main's shape) GitHub validates a reusable workflow's permissions against the calling job when it parses the caller. A callee that requests a scope the caller does not grant fails the whole caller run at startup, before any job runs. That is what blocks the stable release today: release.yml calls ios-screenshots.yml, which requests `actions: write` while release.yml grants none (#12149). Add scripts/ci/check_reusable_workflow_permissions.py (python3 stdlib only) that walks every local `uses: ./.github/workflows/*.yml` call, computes the calling job's grant (job block, else workflow block, else the repository default) and the callee's request (max over its workflow block and every job block, gated jobs included, mirroring 4b9720d), follows nested calls with the intermediate grant, and fails on any scope that asks for more. tests/test_ci_reusable_workflow_permissions.py covers the rule on fixture trees (the exact #12149 shape, shorthands, job-level overrides, repository defaults, nesting, missing callees) and then runs the checker on the real tree, which fails until the next commit fixes the workflows. Wired into the workflow-guard-tests job in ci.yml. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * ci: stop ios-screenshots.yml requesting actions: write (fixes release startup) The screenshot workflow declared `actions: write` since #6697, but no step ever used it: checkout runs with persist-credentials disabled, the two artifact uploads use the runner's artifact token, the capture is a DEBUG simulator build, and the App Store Connect upload path authenticates with an API key. When #11342 made release.yml call this workflow, GitHub compared the callee's block with the caller's grant (contents/attestations/id-token only) and refused the release workflow at parse time: startup_failure, no job run, for tag pushes and dispatches alike (#12149). Reduce the callee to `contents: read`, the minimum its steps use. Widening release.yml instead would have handed a UI-test job the ability to cancel or dispatch runs for no benefit. The guard added in the previous commit now passes on the tree. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * release: do not gate build-sign-notarize on iOS screenshot capture #11342 made build-sign-notarize need generate-ios-screenshots ("gates build-sign-notarize on screenshot success"). The DMG never consumes those artifacts: nothing in build-sign-notarize downloads them, and the App Store tooling (ios/scripts/appstore-shots.sh capture) dispatches its own ios-screenshots.yml run rather than reading a release run. What the gate did do was make every stable macOS release wait for, and fail with, a 300-minute simulator capture across nine locales on shared macOS runners, a lane that had "not compiled on main for days" before #11342 healed it. Keep the capture in release.yml as a sibling job, so every tag still gets screenshots at the exact release ref and a failed capture still turns the run red, but drop it from build-sign-notarize.needs. Trade-off: a green macOS release no longer implies the screenshot capture succeeded; the run conclusion still does. tests/test_ci_release_ios_screenshots_decoupled.sh pins the policy (fails on main's needs list, passes here) and runs in workflow-guard-tests. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * release: give the screenshot capture job only contents: read and no secrets The screenshot job runs a DEBUG simulator UI test after `brew install` of fastlane and imagemagick. Capture-only needs to read the repository and nothing else: checkout runs with persist-credentials disabled, artifact uploads use the runner's artifact token, and the App Store Connect upload path in ios-screenshots.yml is gated to workflow_dispatch from main, so it is unreachable from a release run whatever `upload` says. Set job-level `permissions: contents: read` on the calling job (the pattern the cmux-tui callers already use) instead of passing the workflow's contents/attestations/id-token write grant through, and drop `secrets: inherit`, which handed every repository secret (Developer ID certificate and password, notarization credentials, Sparkle private key, R2 keys, Sentry token, ASC key) to that job for no benefit. Trade-off: if the release lane ever wants the ASC upload, it must add `secrets: inherit` back together with `upload: true` and relax the callee's dispatch-only guard. That should be a deliberate change. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * release: let the Sparkle monotonic guard warn on non-tag dry runs release.yml runs tests/test_ci_sparkle_build_monotonic.sh at the top of build-sign-notarize. On plain main it fails (CURRENT_PROJECT_VERSION 102 equals the published 0.64.22 build), which is correct for a tag push about to publish but wrong for the workflow's built-in dry run: a non-tag workflow_dispatch publishes nothing and, by design, runs from a branch that has not been bumped yet. The dry run was therefore impossible without a throwaway bump commit. Chosen fix: a CMUX_SPARKLE_MONOTONIC_MODE switch on the guard, `enforce` by default (tag pushes, scripts/release-pretag-guard.sh) and `warn` when release.yml runs from anything but refs/tags/*. Rejected alternative: running the dry run from a throwaway branch with a temporary bump, which would validate a commit that never merges and leave the pipeline un-dry-runnable for everyone else. tests/test_sparkle_build_monotonic_modes.sh drives the guard against fixture project files and a local appcast (stale fails in enforce and by default, warns in warn mode, bumped passes in both, unreachable appcast soft-passes, unknown mode fails) and pins the ref-based selection in release.yml. Wired into workflow-guard-tests.

The budget was 20 x 15s. Nightly run 34208928547 (2026-09-08) exhausted it: Accepted at 09:51:28, still "Unnotarized Developer ID" at 09:56:18, exit 3, whole universal lane failed, while the arm64 and x86_64 lanes passed in the same window. Raise the default to 80 x 15s (twenty minutes) and announce the budget on the first rejection so a log reader can tell propagation from a hang. Trade-off: a genuinely rejected helper now takes up to twenty minutes to fail instead of five, which only delays an already-lost release; a short budget failed good releases, each costing a full rebuild and a human retry. Both knobs remain env-configurable (CMUX_GATEKEEPER_ASSESS_ATTEMPTS/_DELAY_SECONDS). nightly's signing job has an 80-minute timeout with a 7-10 minute typical duration, so the budget fits there; release.yml's timeout is raised in the next commit. tests/test_notarize_computer_use_helper.sh now pins the defaults (at least 1200s, polled at least every 30s, env-configurable literals) and the budget announcement, alongside the existing override and give-up coverage.

Since then the job gained the Cloud tunnel system extension and its Go engine build (#11789), the universal diff sidecar and cmux-tui client install (#12006), two extra smoke launches, and a Gatekeeper propagation wait that can now run twenty minutes on its own. A 60-minute ceiling leaves no room for a slow notarytool day, and a timeout mid-notarization wastes the whole build. 90 minutes covers the measured baseline plus the known variable waits with headroom while still bounding a hung job on a shared self-hosted runner. To be re-checked against the dry-run duration for this branch: the timeout must stay at least 25 percent above it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * release: name the tunnel extension by its bundle identifier, not its App ID The first release dry run that could start after the permission fix (run 34222835589) failed 30 minutes in, at "Verify binary architectures": error: system extension identifier is 'com.cmuxterm.app.tunnel', expected '7WLXT3NR37.com.cmuxterm.app.tunnel' #11789 passed the team-prefixed App ID to scripts/normalize-system-extension-bundle.sh and looked for the tunnel binary under 7WLXT3NR37.com.cmuxterm.app.tunnel.systemextension. The Release build's PRODUCT_BUNDLE_IDENTIFIER for the extension is com.cmuxterm.app.tunnel; only NEMachServiceName ($(CMUX_TEAM_ID_PREFIX)$(PRODUCT_BUNDLE_IDENTIFIER)) and the provisioning profile's com.apple.application-identifier carry the team prefix, and the app activates whatever CFBundleIdentifier the bundled extension declares. nightly.yml already does it this way and ships com.cmuxterm.app.nightly.tunnel.systemextension with a profile for 7WLXT3NR37.com.cmuxterm.app.nightly.tunnel (run 34220568401). The mistake was invisible until now because release.yml could not start at all. Use the bundle identifier for the normalize call and the directory the verify step inspects; keep the App ID for the profile check. tests/test_ci_release_tunnel_identifiers.sh derives all three from cmux.xcodeproj/project.pbxproj (fails on main's release.yml, passes here) and runs in workflow-guard-tests. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * Fix main's package-test compile error and Swift warning-budget violations main is red for every branch that routes the macOS lane (#12161, #12165), which keeps ci-status from ever reporting green on this release-pipeline PR. Fix both at the root rather than refreshing the budget: - swift-package-tests: FakeTerminalEngine.swift gained a `UUID` parameter in #10564 but imports only GhosttyKit. Add `import Foundation`. - tests-build-and-lag (scripts/swift_warning_budget.py, actual > budget): * AppDelegate+PaneMemoryGuardrail.swift: parenthesize the two `compactMap` closures inside the `guard` condition ("trailing closure in this context is confusable with the body of the statement"). * SessionIndexTableController.swift: the bounds-change observer block is typed @sendable in the current SDK, so referencing `isApplyingRows` and `reconcilePresentation(in:)` warned. The block is delivered on `queue: .main`, so run it under `MainActor.assumeIsolated`, the same pattern SidebarWorkspaceRowCellView uses; no async hop, same timing. * CmuxTuiSnapshotParser.swift: `switch resourceID.kind` already covers every SurfaceResourceKind case (terminal, display, browser), so the `default: continue` could never run. Remove it; a new case now fails to compile here instead of being silently skipped. * SurfaceCatalogModel.swift: `if let rowID,` rebound a value the body never read; test `rowID != nil` instead. * TerminalController.swift: `payload` in the `.delivered` branch is never mutated; make it `let`. Every change is behavior-preserving. Verified with `swiftc -parse` on each file locally (no app build on the shared machine); the routed CI lane proves the build and the budget.

This is the output of scripts/normalize-pbxproj.py: three lines reordered, no identifier or setting changed.

The job log shows why: ./scripts/sparkle_generate_appcast.sh: line 93: delta_args[@]: unbound variable A tag push would have published a GitHub Release without appcast.xml, so no Sparkle client would ever be offered the update, and the R2 stable appcast upload would then fail after the release already existed. tests/test_sparkle_generate_appcast_no_deltas.sh runs the real script with fake git/xcodebuild/generate_appcast/sign_update tools under every bash on the machine (/bin/bash 3.2 on macOS reproduces the bug; bash 5 never did) and requires a signed appcast at the requested output path with no delta arguments when there are no previous archives, and with --maximum-deltas when there are. It also requires release.yml to verify the feed after generation instead of trusting the exit status. Fails on main's script and workflow; the next commit fixes both. Wired into workflow-guard-tests. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * release: generate the appcast when there are no previous archives (bash 3.2) #11788 added `delta_args=()` and passed "${delta_args[@]}" to generate_appcast. In bash 4.4+ an empty array expands to nothing; in bash 3.2 (macOS /bin/bash, which `#!/usr/bin/env bash` resolves to on the release runner) it is an "unbound variable" error under `set -u`. Worse, with the script's EXIT trap bash 3.2 then exits 0, so the step passed and no appcast was written. Nightly always has previous archives (delta_args non-empty) and was never affected; the stable release lane never has them and has been broken since 2026-09-03, unnoticed because release.yml could not start at all (#12149). Expand the array as ${delta_args[@]+"${delta_args[@]}"}, which is empty when the array is empty in every bash. In release.yml, verify after generation that appcast.xml exists, carries sparkle:edSignature and references cmux-macos.dmg before anything uploads it: the exit status alone is not a reliable signal on bash 3.2. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * release: fail the Sparkle monotonic guard closed when the appcast is unreachable CodeRabbit on #12157: enforce mode (tag pushes, release-pretag-guard.sh) soft-passed when the published appcast could not be fetched, so a tag push could publish a stale CURRENT_PROJECT_VERSION on a network blip or on a latest release that lacks appcast.xml, the exact state that leaves Sparkle clients without updates. A missing signal must fail closed when the run is about to publish. enforce mode now fails with an explanation when the published build is unknown; warn mode (non-tag dry runs) keeps the soft pass because it publishes nothing. curl retries transient failures (3 x 2s by default, overridable so the tests exercise the unreachable path without waiting). tests/test_sparkle_build_monotonic_modes.sh covers enforce, default and warn against an unreachable appcast.

It updated the Python hook tests to the new wire contract but not ClaudeHookLifecycleCleanupTests, whose two moved-pane tests still expected the removed command. They fail on main in the strict app-host agent-notification step (shard 6), unnoticed because #11976's PR CI never routed the macOS lane. Assert the new contract instead: the journal event for the hook names the re-homed workspace and the live pane (via the existing AgentJournalAppendCapture parser), and nothing still wipes the whole destination workspace. SessionEnd keeps sending the v1 command, so its tests are unchanged. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * ci: make app-host hangs fail in minutes instead of the 75-minute job timeout Every macOS lane run since 2026-09-03 has ended with app-host shards "cancelled" at the 75-minute job timeout. Today's logs (run 34236235360, shards 1/2/4, both attempts) show the mechanism, and it is two plumbing defects rather than the tests: 1. scripts/ci/xcodebuild_noninteractive.py resets its 300s idle deadline on every output chunk. Since #11755 (merged 2026-09-03T02:09Z, after the last green lane at 2026-09-02T09:21Z) the app host logs every Cloud API poll, `[CloudVM] GET /api/vm not_signed_in`, every 45 seconds. A test host hung inside a WebKit page load (WebContent XPC: "Could not signal service ... 113") therefore never looks idle, so the wrapper's kill and retry path, which handled the same WebKit failure on the 09-02 green run, never fires. 2. The tolerant batch watchdog in ci.yml (1800s) killed only the console-session launcher and left the lock wrapper, xcodebuild and the app host alive; the app host kept the `| tee` pipe open, so the step sat idle from "timeout after 1800s; terminating" until the job timeout. Fixes: - CMUX_XCODEBUILD_NONINTERACTIVE_IDLE_IGNORE_RE: output lines matching it do not count as progress. run-app-host-xcodebuild.sh defaults it to the Cloud poll line (an empty value restores counting everything; an invalid regex fails closed with exit 2). Real output still resets the clock, so a slow but progressing batch is unaffected. - The ci.yml batch runner writes xcodebuild output to the capture file and streams it with a detached tail, kills the whole process tree (pgrep -P recursion, TERM then KILL) when the batch budget expires, and reads both the streamed and per-batch captures for the SwiftPM retry heuristic. Behavior tests: tests/test_ci_xcodebuild_noninteractive_helper.py drives a child that prints only the keepalive every 50ms (finishes without the pattern, idles out at 0.3s with it, invalid pattern exits 2); tests/test_ci_change_areas.py runs the real step script against a runner that hangs and leaves a grandchild holding stdout, and requires exit 124 within seconds with the grandchild dead.

Keep the pinned line and append the per-batch captures on the next line instead. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * ci: keep a watchdog-killed app-host batch terminal; drop the wall-clock assert CodeRabbit on #12157: the expected-failure normalization in run_unit_test_batch greps the capture for the last "Executed ... failures" summary and returns success on "(0 unexpected)". After the watchdog kills a batch (status 124) the capture can still hold an earlier attempt's summary (run-app-host-xcodebuild.sh retries into the same file), so a terminated batch could be reported as passed. Treat 124 as terminal before the normalization. The hung-runner behavior test now prints a decoy "(0 unexpected)" summary before hanging and requires the step to stay at 124 without the "All failures ... are expected" message. Also drop the `elapsed < 60` assertion from that test: the harness's 120s subprocess timeout already bounds a runaway step, and a hard wall-clock ceiling only adds scheduler-delay flakes.

Serve those two tests from the detached mock server instead, which owns no expectation, and keep the waited path for every other Coderouter test.

Capture each suite's output and rerun the suite exactly once, only when xcodebuild printed "Restarting after unexpected exit, crash, or test timeout". An assertion failure never earns a rerun and a second crash still fails the shard, so the gate keeps rejecting real regressions. tests/test_ci_change_areas.py drives the real step script against a fake console runner: crash-then-pass is green with three invocations, an assertion failure exits 65 after one invocation, and two crashes exit 65 after two.

When the first connection's handler reached that check after the replacement had already recorded, it promoted `first` instead, superseded the freshly admitted replacement, and the replacement's own markUsable returned false: "Expectation failed: await admission.markUsable()" at CmxIrohEndpointServerTests.swift:353 in CI run 34414741413 (swift-package-tests), while the previous run passed the same code. Admit before recording so the test's `recorder.next()` proves `first` is active before `replacement` is enqueued, and promote only the replacement by identity.

The hang sample shows SSHPTYAttachReconnectInputFilterTests.stdinPumpFiltersReadyInputBeforeStopSignal parked in stopFiltering() -> read() on the stop-acknowledgement pipe with every other visible cooperative-pool thread also inside a test body's synchronous wait. The pump under test is a detached task that needs one of those same threads, and the five pump tests each hold a thread for the ~13s reconnect probe deadline while running concurrently, so the suite can leave no thread for any pump (the family issue #12180 tracks). Run the suite serialized so at most one test parks a thread at a time, and bound every wait: stopFiltering now takes a 30s acknowledgement timeout and must succeed, and the EOF/exact reads poll with the same deadline. A pump that never gets scheduled now fails its test inside the batch instead of parking the shard until the idle timeout retries are exhausted. The two assertions in this suite that already fail on main (readUntilEOF == forwardedInput in stdinPumpFiltersReadyInputBeforeStopSignal and stdinPumpKeepsFilteringLateProbeRepliesAfterInitialDrain) are unchanged; the batch classifier tolerates them today.

…rkflow permissions guard, screenshot decoupling, notarization hardening) (manaflow-ai#12157) * ci: guard reusable-workflow permission grants (red on main's shape) GitHub validates a reusable workflow's permissions against the calling job when it parses the caller. A callee that requests a scope the caller does not grant fails the whole caller run at startup, before any job runs. That is what blocks the stable release today: release.yml calls ios-screenshots.yml, which requests `actions: write` while release.yml grants none (manaflow-ai#12149). Add scripts/ci/check_reusable_workflow_permissions.py (python3 stdlib only) that walks every local `uses: ./.github/workflows/*.yml` call, computes the calling job's grant (job block, else workflow block, else the repository default) and the callee's request (max over its workflow block and every job block, gated jobs included, mirroring 4b9720d), follows nested calls with the intermediate grant, and fails on any scope that asks for more. tests/test_ci_reusable_workflow_permissions.py covers the rule on fixture trees (the exact manaflow-ai#12149 shape, shorthands, job-level overrides, repository defaults, nesting, missing callees) and then runs the checker on the real tree, which fails until the next commit fixes the workflows. Wired into the workflow-guard-tests job in ci.yml.

When manaflow-ai#11342 made release.yml call this workflow, GitHub compared the callee's block with the caller's grant (contents/attestations/id-token only) and refused the release workflow at parse time: startup_failure, no job run, for tag pushes and dispatches alike (manaflow-ai#12149). Reduce the callee to `contents: read`, the minimum its steps use. Widening release.yml instead would have handed a UI-test job the ability to cancel or dispatch runs for no benefit. The guard added in the previous commit now passes on the tree. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * release: do not gate build-sign-notarize on iOS screenshot capture manaflow-ai#11342 made build-sign-notarize need generate-ios-screenshots ("gates build-sign-notarize on screenshot success"). The DMG never consumes those artifacts: nothing in build-sign-notarize downloads them, and the App Store tooling (ios/scripts/appstore-shots.sh capture) dispatches its own ios-screenshots.yml run rather than reading a release run. What the gate did do was make every stable macOS release wait for, and fail with, a 300-minute simulator capture across nine locales on shared macOS runners, a lane that had "not compiled on main for days" before manaflow-ai#11342 healed it. Keep the capture in release.yml as a sibling job, so every tag still gets screenshots at the exact release ref and a failed capture still turns the run red, but drop it from build-sign-notarize.needs. Trade-off: a green macOS release no longer implies the screenshot capture succeeded; the run conclusion still does. tests/test_ci_release_ios_screenshots_decoupled.sh pins the policy (fails on main's needs list, passes here) and runs in workflow-guard-tests. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * release: give the screenshot capture job only contents: read and no secrets The screenshot job runs a DEBUG simulator UI test after `brew install` of fastlane and imagemagick. Capture-only needs to read the repository and nothing else: checkout runs with persist-credentials disabled, artifact uploads use the runner's artifact token, and the App Store Connect upload path in ios-screenshots.yml is gated to workflow_dispatch from main, so it is unreachable from a release run whatever `upload` says. Set job-level `permissions: contents: read` on the calling job (the pattern the cmux-tui callers already use) instead of passing the workflow's contents/attestations/id-token write grant through, and drop `secrets: inherit`, which handed every repository secret (Developer ID certificate and password, notarization credentials, Sparkle private key, R2 keys, Sentry token, ASC key) to that job for no benefit. Trade-off: if the release lane ever wants the ASC upload, it must add `secrets: inherit` back together with `upload: true` and relax the callee's dispatch-only guard. That should be a deliberate change.

On plain main it fails (CURRENT_PROJECT_VERSION 102 equals the published 0.64.22 build), which is correct for a tag push about to publish but wrong for the workflow's built-in dry run: a non-tag workflow_dispatch publishes nothing and, by design, runs from a branch that has not been bumped yet. The dry run was therefore impossible without a throwaway bump commit. Chosen fix: a CMUX_SPARKLE_MONOTONIC_MODE switch on the guard, `enforce` by default (tag pushes, scripts/release-pretag-guard.sh) and `warn` when release.yml runs from anything but refs/tags/*. Rejected alternative: running the dry run from a throwaway branch with a temporary bump, which would validate a commit that never merges and leave the pipeline un-dry-runnable for everyone else. tests/test_sparkle_build_monotonic_modes.sh drives the guard against fixture project files and a local appcast (stale fails in enforce and by default, warns in warn mode, bumped passes in both, unreachable appcast soft-passes, unknown mode fails) and pins the ref-based selection in release.yml. Wired into workflow-guard-tests.

The budget was 20 x 15s. Nightly run 34208928547 (2026-09-08) exhausted it: Accepted at 09:51:28, still "Unnotarized Developer ID" at 09:56:18, exit 3, whole universal lane failed, while the arm64 and x86_64 lanes passed in the same window. Raise the default to 80 x 15s (twenty minutes) and announce the budget on the first rejection so a log reader can tell propagation from a hang. Trade-off: a genuinely rejected helper now takes up to twenty minutes to fail instead of five, which only delays an already-lost release; a short budget failed good releases, each costing a full rebuild and a human retry. Both knobs remain env-configurable (CMUX_GATEKEEPER_ASSESS_ATTEMPTS/_DELAY_SECONDS). nightly's signing job has an 80-minute timeout with a 7-10 minute typical duration, so the budget fits there; release.yml's timeout is raised in the next commit. tests/test_notarize_computer_use_helper.sh now pins the defaults (at least 1200s, polled at least every 30s, env-configurable literals) and the budget announcement, alongside the existing override and give-up coverage.

Since then the job gained the Cloud tunnel system extension and its Go engine build (manaflow-ai#11789), the universal diff sidecar and cmux-tui client install (manaflow-ai#12006), two extra smoke launches, and a Gatekeeper propagation wait that can now run twenty minutes on its own. A 60-minute ceiling leaves no room for a slow notarytool day, and a timeout mid-notarization wastes the whole build. 90 minutes covers the measured baseline plus the known variable waits with headroom while still bounding a hung job on a shared self-hosted runner. To be re-checked against the dry-run duration for this branch: the timeout must stay at least 25 percent above it.

The Release build's PRODUCT_BUNDLE_IDENTIFIER for the extension is com.cmuxterm.app.tunnel; only NEMachServiceName ($(CMUX_TEAM_ID_PREFIX)$(PRODUCT_BUNDLE_IDENTIFIER)) and the provisioning profile's com.apple.application-identifier carry the team prefix, and the app activates whatever CFBundleIdentifier the bundled extension declares. nightly.yml already does it this way and ships com.cmuxterm.app.nightly.tunnel.systemextension with a profile for 7WLXT3NR37.com.cmuxterm.app.nightly.tunnel (run 34220568401). The mistake was invisible until now because release.yml could not start at all. Use the bundle identifier for the normalize call and the directory the verify step inspects; keep the App ID for the profile check. tests/test_ci_release_tunnel_identifiers.sh derives all three from cmux.xcodeproj/project.pbxproj (fails on main's release.yml, passes here) and runs in workflow-guard-tests.

Fix both at the root rather than refreshing the budget: - swift-package-tests: FakeTerminalEngine.swift gained a `UUID` parameter in manaflow-ai#10564 but imports only GhosttyKit. Add `import Foundation`. - tests-build-and-lag (scripts/swift_warning_budget.py, actual > budget): * AppDelegate+PaneMemoryGuardrail.swift: parenthesize the two `compactMap` closures inside the `guard` condition ("trailing closure in this context is confusable with the body of the statement"). * SessionIndexTableController.swift: the bounds-change observer block is typed @sendable in the current SDK, so referencing `isApplyingRows` and `reconcilePresentation(in:)` warned. The block is delivered on `queue: .main`, so run it under `MainActor.assumeIsolated`, the same pattern SidebarWorkspaceRowCellView uses; no async hop, same timing. * CmuxTuiSnapshotParser.swift: `switch resourceID.kind` already covers every SurfaceResourceKind case (terminal, display, browser), so the `default: continue` could never run. Remove it; a new case now fails to compile here instead of being silently skipped. * SurfaceCatalogModel.swift: `if let rowID,` rebound a value the body never read; test `rowID != nil` instead. * TerminalController.swift: `payload` in the `.delivered` branch is never mutated; make it `let`. Every change is behavior-preserving. Verified with `swiftc -parse` on each file locally (no app build on the shared machine); the routed CI lane proves the build and the budget.

The job log shows why: ./scripts/sparkle_generate_appcast.sh: line 93: delta_args[@]: unbound variable A tag push would have published a GitHub Release without appcast.xml, so no Sparkle client would ever be offered the update, and the R2 stable appcast upload would then fail after the release already existed. tests/test_sparkle_generate_appcast_no_deltas.sh runs the real script with fake git/xcodebuild/generate_appcast/sign_update tools under every bash on the machine (/bin/bash 3.2 on macOS reproduces the bug; bash 5 never did) and requires a signed appcast at the requested output path with no delta arguments when there are no previous archives, and with --maximum-deltas when there are. It also requires release.yml to verify the feed after generation instead of trusting the exit status. Fails on main's script and workflow; the next commit fixes both. Wired into workflow-guard-tests.

In bash 4.4+ an empty array expands to nothing; in bash 3.2 (macOS /bin/bash, which `#!/usr/bin/env bash` resolves to on the release runner) it is an "unbound variable" error under `set -u`. Worse, with the script's EXIT trap bash 3.2 then exits 0, so the step passed and no appcast was written. Nightly always has previous archives (delta_args non-empty) and was never affected; the stable release lane never has them and has been broken since 2026-09-03, unnoticed because release.yml could not start at all (manaflow-ai#12149). Expand the array as ${delta_args[@]+"${delta_args[@]}"}, which is empty when the array is empty in every bash. In release.yml, verify after generation that appcast.xml exists, carries sparkle:edSignature and references cmux-macos.dmg before anything uploads it: the exit status alone is not a reliable signal on bash 3.2.

A missing signal must fail closed when the run is about to publish. enforce mode now fails with an explanation when the published build is unknown; warn mode (non-tag dry runs) keeps the soft pass because it publishes nothing. curl retries transient failures (3 x 2s by default, overridable so the tests exercise the unreachable path without waiting). tests/test_sparkle_build_monotonic_modes.sh covers enforce, default and warn against an unreachable appcast.

It updated the Python hook tests to the new wire contract but not ClaudeHookLifecycleCleanupTests, whose two moved-pane tests still expected the removed command. They fail on main in the strict app-host agent-notification step (shard 6), unnoticed because manaflow-ai#11976's PR CI never routed the macOS lane. Assert the new contract instead: the journal event for the hook names the re-homed workspace and the live pane (via the existing AgentJournalAppendCapture parser), and nothing still wipes the whole destination workspace. SessionEnd keeps sending the v1 command, so its tests are unchanged.

Today's logs (run 34236235360, shards 1/2/4, both attempts) show the mechanism, and it is two plumbing defects rather than the tests: 1. scripts/ci/xcodebuild_noninteractive.py resets its 300s idle deadline on every output chunk. Since manaflow-ai#11755 (merged 2026-09-03T02:09Z, after the last green lane at 2026-09-02T09:21Z) the app host logs every Cloud API poll, `[CloudVM] GET /api/vm not_signed_in`, every 45 seconds. A test host hung inside a WebKit page load (WebContent XPC: "Could not signal service ... 113") therefore never looks idle, so the wrapper's kill and retry path, which handled the same WebKit failure on the 09-02 green run, never fires. 2. The tolerant batch watchdog in ci.yml (1800s) killed only the console-session launcher and left the lock wrapper, xcodebuild and the app host alive; the app host kept the `| tee` pipe open, so the step sat idle from "timeout after 1800s; terminating" until the job timeout. Fixes: - CMUX_XCODEBUILD_NONINTERACTIVE_IDLE_IGNORE_RE: output lines matching it do not count as progress. run-app-host-xcodebuild.sh defaults it to the Cloud poll line (an empty value restores counting everything; an invalid regex fails closed with exit 2). Real output still resets the clock, so a slow but progressing batch is unaffected. - The ci.yml batch runner writes xcodebuild output to the capture file and streams it with a detached tail, kills the whole process tree (pgrep -P recursion, TERM then KILL) when the batch budget expires, and reads both the streamed and per-batch captures for the SwiftPM retry heuristic. Behavior tests: tests/test_ci_xcodebuild_noninteractive_helper.py drives a child that prints only the keepalive every 50ms (finishes without the pattern, idles out at 0.3s with it, invalid pattern exits 2); tests/test_ci_change_areas.py runs the real step script against a runner that hangs and leaves a grandchild holding stdout, and requires exit 124 within seconds with the grandchild dead.

Keep the pinned line and append the per-batch captures on the next line instead.

After the watchdog kills a batch (status 124) the capture can still hold an earlier attempt's summary (run-app-host-xcodebuild.sh retries into the same file), so a terminated batch could be reported as passed. Treat 124 as terminal before the normalization. The hung-runner behavior test now prints a decoy "(0 unexpected)" summary before hanging and requires the step to stay at 124 without the "All failures ... are expected" message. Also drop the `elapsed < 60` assertion from that test: the harness's 120s subprocess timeout already bounds a runaway step, and a hard wall-clock ceiling only adds scheduler-delay flakes.

The shared accept loop fulfills that expectation when the listener closes at the end of the helper, so XCTest ended `testCoderouterUnknownVerbStillPassesThroughToTheInstalledCLI` and `testCoderouterClaudeAddOAuthTokenRejectsAPIKeyShapeBeforeTheSocket` with "Failed due to unwaited expectation", which it counts as an *unexpected* failure. Since manaflow-ai#12207 the app-host batch classifier fails a batch on any unexpected failure, so this one test turned shard 5 (and the sibling test shard 6) red on main and on every PR: run 34401456032, main run 34342638735 attempts 1 and 2. Serve those two tests from the detached mock server instead, which owns no expectation, and keep the waited path for every other Coderouter test. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * ci: rerun a remote tmux mirror suite once after an app-host crash The non-tolerant "Run remote tmux mirror detach and placement regressions" gate on shard 6 fails whenever the app host crashes mid-suite, which manaflow-ai#9348 documents as nondeterministic: the crash point moves between tests and the relaunched host passes the rest (run 34401456032 crashed in dedicatedWindowSocketDefaultsToFocusNeutral; the previous run and both main attempts passed the same step). Capture each suite's output and rerun the suite exactly once, only when xcodebuild printed "Restarting after unexpected exit, crash, or test timeout". An assertion failure never earns a rerun and a second crash still fails the shard, so the gate keeps rejecting real regressions. tests/test_ci_change_areas.py drives the real step script against a fake console runner: crash-then-pass is green with three invocations, an assertion failure exits 65 after one invocation, and two crashes exit 65 after two.

When the first connection's handler reached that check after the replacement had already recorded, it promoted `first` instead, superseded the freshly admitted replacement, and the replacement's own markUsable returned false: "Expectation failed: await admission.markUsable()" at CmxIrohEndpointServerTests.swift:353 in CI run 34414741413 (swift-package-tests), while the previous run passed the same code. Admit before recording so the test's `recorder.next()` proves `first` is active before `replacement` is enqueued, and promote only the replacement by identity. The suite passes three consecutive local runs. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * cmuxTests: serialize the stdin pump suite and bound its blocking waits Shard 3 of CI run 34414741413 hung three times at the app-host wrapper's 300s idle timeout in the same batch. The hang sample shows SSHPTYAttachReconnectInputFilterTests.stdinPumpFiltersReadyInputBeforeStopSignal parked in stopFiltering() -> read() on the stop-acknowledgement pipe with every other visible cooperative-pool thread also inside a test body's synchronous wait. The pump under test is a detached task that needs one of those same threads, and the five pump tests each hold a thread for the ~13s reconnect probe deadline while running concurrently, so the suite can leave no thread for any pump (the family issue manaflow-ai#12180 tracks). Run the suite serialized so at most one test parks a thread at a time, and bound every wait: stopFiltering now takes a 30s acknowledgement timeout and must succeed, and the EOF/exact reads poll with the same deadline. A pump that never gets scheduled now fails its test inside the batch instead of parking the shard until the idle timeout retries are exhausted. The two assertions in this suite that already fail on main (readUntilEOF == forwardedInput in stdinPumpFiltersReadyInputBeforeStopSignal and stdinPumpKeepsFilteringLateProbeRepliesAfterInitialDrain) are unchanged; the batch classifier tolerates them today.

Medium Risk
Changes when sharded app-host CI passes vs fails; misclassified logs could block merges or briefly allow bad runs, but the logic is intentionally conservative.
Overview
Tightens app-host unit-test batch handling so CI no longer treats a failed
xcodebuildas green by reading only the lastExecuted … (0 unexpected)line.App-host batches now call
scripts/ci/classify-app-host-test-output.py, which scans every XCTest summary in the log and tolerates the run only when exit code is 65 and no unexpected failures appear anywhere. Crashes, timeouts, missing summaries, and earlier unexpected failures stay red.Workflow guard tests run
tests/test_ci_app_host_test_output.py, andtests/test_ci_change_areas.pysimulates a second batch that crashes without a summary (exit 9 instead of 65) so a prior expected-failure batch cannot mask it.Reviewed by Cursor Bugbot for commit ded2e80.
