ci: build the nightly app on cmux15's trusted runner first, Blacksmith as fallback - #14821
Merged
Merged
Conversation
…h as fallback build-nightly-app was hard-coded to blacksmith-12vcpu-macos-26, so a push to main never considered an owned mini (run 36239331473). Attempt 1 of a push or schedule run on main now asks for vars.CI_SEED_TRUSTED_POOL, the trusted owned pool (no pull request runners; the glaeda hook admits only main's push and schedule jobs), because the job holds the ci-cache-writer R2 keys and the Sentry token and its app is signed and shipped. Forks, rc/**, dispatches, fast dogfood and re-runs keep Blacksmith. - owned_pool_rescue.py / ci-owned-pool-rescue.yml: watch nightly.yml runs like a picker-less side lane (NIGHTLY_WORKFLOW_PATH). Recognise glaeda-trusted-* labels. Allow one queue round behind a DerivedData seed. A stuck or refused build is re-run on Blacksmith, unless a newer nightly run on main is still pending. - nightly.yml: an owned runner folds its workspace path into the release compile-cache key, so the mini and Blacksmith lineages never evict each other (Blacksmith's key is unchanged). Clear build outputs a persistent runner kept. - runner_label_policy.py: CI_SEED_TRUSTED_POOL may only name a glaeda-trusted-* label; the health report and variable check read it. - Signing and notarization stay on Blacksmith (unproven on owned Macs; #6264). Docs list every macOS job's route. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Merge Risk: 🟡 Moderate · up to A stuck nightly app build can be cancelled without a replacement build. Fix the rescue supersession check before merging, and restrict or confirm the approved runner-label configuration. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The new runner selection is restricted to main-branch builds and requires two trusted-runner labels. However, its configuration check accepts runner names other than the intended build machine. A misconfiguration could place a build that uses sensitive credentials and produces a shipped app on another trusted machine with a different workload. Retained concerns

their existing behavior.
- Around line 805-807: Update rescue() so it treats a newer unfinished run as

Ignore runs where build-nightly-app is skipped, and preserve the existing

GitHub Actions REST API rerun-failed-jobs cancelled job conclusion rerun cancelled jobs
💡 Result:
`POST /repos/{owner}/{repo}/actions/runs/{run_id}/rerun-failed-jobs` is documented to rerun **failed jobs and their dependent jobs**. GitHub’s docs don’t say that it includes jobs whose conclusion is `cancelled`, so don’t rely on this endpoint to rerun cancelled jobs. [1]
For a specific cancelled job, use the job rerun endpoint:
```http
POST /repos/{owner}/{repo}/actions/jobs/{job_id}/rerun
```
That endpoint reruns the specified job and its dependents. Or rerun the entire workflow with `POST /repos/{owner}/{repo}/actions/runs/{run_id}/rerun`. [1]
You can inspect job conclusions with the [list-jobs endpoint](https://docs.github.com/en/rest/actions/workflow-jobs#list-jobs-for-a-workflow-run); it reports each job’s status and conclusion. [2]
Use a full rerun for cancelled nightly builds.
target.side makes nightly rescue call rerun-failed-jobs after cancellation. That endpoint reruns failed jobs and their dependents, but it does not establish reruns for a job whose conclusion is cancelled. The nightly build and its dependent publishing jobs can therefore remain skipped.
Use a full workflow rerun for a stuck nightly build. Keep failed-only reruns for refused nightly jobs.

Do not treat every unfinished nightly run as a replacement app build.
The six-hour schedule run can remain unfinished while build-nightly-app is skipped. newer_unfinished_runs() filters by workflow, branch, run ID, and status only. It does not check whether the run will build or publish an app. rescue() can therefore cancel the stuck app-producing run without rerunning it.
Require the newer run to be an app-producing nightly run before using it as a superseding run.

Both trusted minis carry glaeda-trusted-std-xcode-26.6, but cmuxs-mac-mini-6 also runs the team dev-build worker as the same user, so the shipped build should never land there. Seeding keeps both, so CI_SEED_TRUSTED_POOL is unchanged. build-nightly-app now asks for ["<CI_SEED_TRUSTED_POOL>", "<CI_NIGHTLY_TRUSTED_RUNNER>"]: the trusted pool and one runner's own glaeda-runner-<name> label (glaeda-cmux-runner's runner_label()). Either variable empty means Blacksmith, so this is inert until cmux15's runner is re-registered with that label and the variable is set. - runner_label_policy.py: CI_NIGHTLY_TRUSTED_RUNNER may only be a lowercase glaeda-runner-* label (also safe inside the JSON runs-on). - ci-health-report.yml / ci-repo-variables.yml: report it. - ci-owned-pool-rescue.yml: watch nightly runs only while both are set. - Docs and tests follow.

Why
Owned minis should be the first choice for every macOS job they can run, with Blacksmith as overflow. Pull request jobs already work this way. Several non-PR jobs are still hard-coded to Blacksmith. The trigger was run 36239331473 (push to main):
build-nightly-appran onblacksmith-12vcpu-macos-26because itsruns-onnever considered a mini.What moves
nightly.ymlbuild-nightly-appnow tries one trusted owned mini first: cmux15. On attempt 1 of a push or schedule run onmain, whileCI_PR_POOL_OWNED == 1, it asks for["<vars.CI_SEED_TRUSTED_POOL>", "<vars.CI_NIGHTLY_TRUSTED_RUNNER>"]. Only a runner carrying both the trusted pool label and its ownglaeda-runner-<name>label can take the job. In every other case it falls back to the existing Blacksmith 12 vCPU expression: forks,rc/**, dispatches, fast dogfood, re-runs, or either variable empty.Why cmux15 only, not mini-6. Both carry
glaeda-trusted-std-xcode-26.6, so seeding keeps using both. mini-6 also runs the team dev-build worker as the same user, and hosts ci-dash, subrouter-dash and tunnels. cmux15 has no PR runners and no dev-build worker. Over the last 24.7 h it ran 70 jobs, allseed, all admitted, at about 40% utilisation with a p50 of 504 s, so it has headroom.CI_SEED_TRUSTED_POOLitself is not narrowed.The label does not exist on cmux15 yet. It carries no unique label today; its runner was registered before glaeda started adding
glaeda-runner-<name>to root runners. Current glaeda main already addsglaeda-runner-cmux15-glaedawhen the runner is registered again from the manifest; theglaeda-cmux-runner --manifest … --member cmux15plan shows it. Until the label exists and the variable is set, nothing changes and the job stays on Blacksmith.Hook.
trusted_refusalalready admits main's push and schedule runs. glaeda-cmux-runner-hook: class cmux's nightly app build as isolated teamleaderleo/glaeda#1287 classesnightly.yml/build-nightly-appasisolated(2 units, no token). As an unknown id it would take thecompileclass and hold the canonical root that a seed on the same mini waits for.Why the trusted pool and not the PR pool (
glaeda-std). This job holds theci-cache-writerR2 keys andSENTRY_AUTH_TOKEN, and its unsigned app is whatbuild-sign-notarize-nightlysigns and ships. The PR pool minis run pull request code and keep state between jobs. The repo already refuses owned PR minis forci-cache-writerjobs (ios_runner_pool.owned_blocker: "seed_cache runs in the ci-cache-writer environment with the R2 write keys"). The trusted pool is the owned pool built for this case. Its runners have no pull request runners, and the glaeda hook (trusted_refusalinglaeda-cmux-runner-hook) admits only main's own push and schedule jobs.seed-derived-data.ymlalready writes R2 seeds from it with the same environment, so the environment and its secrets are proven on self-hosted runners.Fallback uses the existing rescue, not a new mechanism. The job has no picker, like the side lanes.
ci-owned-pool-rescue.ymlnow also triggers onNightly macOS build(workflow_run: requested).owned_pool_rescue.pywatches it as a side lane (NIGHTLY_WORKFLOW_PATH,Target.nightly), andjob_poolnow recognisesglaeda-(root-)trusted-*labels.CI_OWNED_POOL_RESCUE_SECONDSplus oneQUEUE_ROUND_SECONDS(900 s). The extra round exists because the same minis seed DerivedData on every push, and a seed takes 5–7 min. The run is cancelled and its failed and cancelled jobs are re-run on Blacksmith.nightly.yml's concurrency group never cancels in progress, so a re-run would join the group and cancel the pending newer run. A stuck run is still cancelled, so the newer run can start.Compile-cache key. The minis run the same Xcode build as Blacksmith (Xcode 26.6, 17F113;
CMUX_CI_XCODE_APP_MACOS_26=/Applications/Xcode_26.6.app), so OS, arch and toolchain would collide. The workspace path differs, so mini entries would mostly miss on Blacksmith and push Blacksmith's own entry out of the prefix restore. On a*-glaeda[-K]runner the key step now folds the workspace path into the toolchain hash. Each lineage restores only its own entries, and the Blacksmith key bytes are unchanged.Workspace reuse. The job already clears stale git locks. It now also clears
build-universalandremote-daemon-assetsby name after checkout (scripts/ci/clear-dirs.sh), so a stale product or dSYM from an earlier job can never ship.Timeouts and speed. The one universal Release build measured on a mini (run 36010907785, ci: try the nightly app compile on an owned Mac mini first, Blacksmith fallback #14208) compiled in 15.5 min. The Blacksmith 12 vCPU job took 16 min in run 36239331473. The 90 min timeout is unchanged.
Guard rails.
runner_label_policy.pynow accepts only these values:CI_SEED_TRUSTED_POOL:glaeda-trusted-<class>-xcode-<version>or empty. A PR pool label there would put these credentials on PR machines.CI_NIGHTLY_TRUSTED_RUNNER(new):glaeda-runner-<lowercase name>or empty. This shape also keeps the value safe inside the JSONruns-onarray. Even a PR runner's name label could match nothing here, because PR runners never carry the trusted pool label.ci-health-report.ymlandci-repo-variables.ymlreport both. No repo variable was changed.To turn it on (owner)
