The complete local durable-L3 stack will run restart and restore qualification on Linux CPU, macOS Metal, and Windows CPU once its supporting workflow plumbing and feature stack are present on main.

This PR is now the catalog-only activation required by the protected planner. The planner intentionally requires ci/slices.yml to match the default-branch catalog during ordinary feature PRs, so the safe landing sequence is:

  1. land dormant workflow plumbing in ci(skippy): stage durable L3 qualification plumbing #1743 with the catalog unchanged;
  2. land the durable-L3 feature stack;
  3. rebase and land this catalog-only activation.

Linux and macOS activate the dense and recurrent product suites. Windows activates the durable-L3 phase on the composed CPU product.

Stack

Validation

  • git diff --check
  • actionlint -config-file .github/actionlint.yaml
  • python3 -m unittest -v scripts.tests.test_ci_workflow_artifacts scripts.tests.test_plan_ci — 50 passed

The branch was rebased onto the exact #1514 head. Its unique diff is limited to ci/slices.yml and the two planner/workflow contract test files at 4fdab0f070edca9d18938642ecf974d595f4ddf6.

Summary by CodeRabbit

  • CI Improvements
    • Added product-integration smoke coverage for Linux CPU, macOS Metal, and Windows CPU environments.
    • Updated platform smoke coverage to use product-integration checks where applicable.
    • Added explicit platform and backend details for Metal model loading validation.
    • Expanded CI planning and workflow validation to include the new smoke test scenarios.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Update the protected planner catalog before enabling these rows.

On pull_request runs, .github/actions/plan-ci/action.yml compares git show "$SOURCE_SHA:ci/slices.yml" with the checked-out catalog and exits when they differ. The Linux, macOS, and Windows planner jobs all use this action, so each plan fails before its lane can schedule the new smoke rows. Land the protected-catalog update, then rebase or enable these rows.

Confirmed at exact head 4fdab0f: the ten failures are the intended protected-catalog guard. This activation PR must remain blocked until dormant planner plumbing #1743 lands and the protected catalog is synchronized; enabling the rows earlier would bypass the repository sequencing contract. Leaving this thread open as the explicit landing-order blocker.

@i386, acknowledged. The finding remains valid and the thread will remain open.

Land #1743 and synchronize the protected catalog before this activation PR enables the durable-L3 smoke rows. This preserves the planner sequencing contract.

Learning: For the durable-L3 smoke-row activation in `ci/slices.yml`, the protected planner catalog guard must intentionally block the PR until dormant planner plumbing in GitHub PR `#1743` lands and synchronizes the protected catalog. Enabling the rows before that sequence would bypass the repository sequencing contract.

Not approving yet — CI is red across every lane, and the cause looks structural rather than flaky.

Every Plan * job fails at the same point:

source slice catalog differs from the protected planner catalog

The plan action compares ci/slices.yml against the protected planner catalog resolved from the base ref. This PR edits the catalog directly — adding product-integration-cpu / -metal / -windows-cpu to smoke_rows, adding platform/backend to metal-model-load, and rewiring the split-serving, platform-macos and platform-windows domain mappings — so the guard trips before anything else runs, and the five PR / * gates then fail on PLAN_RESULT: failure. Nothing downstream ever executes, so the three test files this PR updates have not actually been exercised.

Worth noting the base is skippy-disaggregation (#1514), which is still a draft carrying a changes-requested review. #1743 makes the same class of catalog edit against main and its planner check passes, which points at the base ref rather than the edit itself.

Two things would unblock it: retarget onto whichever branch owns the protected catalog these rows belong to, and confirm the planner-authority path this change is supposed to go through — if catalog rows require a separate authority step, the diff needs to carry it. Happy to re-review once the plan job gets past the catalog guard; the diff itself is small and reads fine.

Superseded by consolidated integration PR #1838. The focused branch and review history remain available; further production wiring continues from the consolidated head.
