fix(e2e): pin Portable rootless Podman runtime

[senthilr-nv]

Summary

The automatic Portable rootless job previously accepted a moving Ubuntu image and unpinned Podman package, so it exercised an unvalidated Podman 4.9 runtime and failed during the first registry container start. This change pins the accepted Ubuntu 26.04 and Podman 5.7 matrix, applies the validated pasta AppArmor correction, and verifies the runtime contract before the live test starts.

Related Issue

Fixes #9006

Changes

• Run the rootless-linux job on Ubuntu 26.04 with the exact 5.7.0+ds2-3build1 Podman package and assert both package and runtime versions.
• Apply and verify the existing pasta signal policy correction before live product execution.
• Extend the workflow contract to protect catalogue compilation and the OS, package, policy, and live-test ordering.
• Configure actionlint to recognize the required ubuntu-26.04 runner label and assert that the rootless-linux job uses it.
• Require actionlint labels to remain an array containing ubuntu-26.04 and preserve the AppArmor file, include, conditional insertion, uniqueness, and reload guards.

📝 Walkthrough

Walkthrough

The portable rootless Linux E2E workflow targets Ubuntu 26.04, pins Podman to 5.7.0+ds2-3build1, prepares the pasta AppArmor profile, and validates these requirements with one consolidated contract test.

Changes

Portable rootless runtime

Layer / File(s)	Summary
Pin runtime environment .github/workflows/portable-profile-e2e.yaml	The job uses Ubuntu 26.04. Runtime setup installs Podman 5.7.0+ds2-3build1 and verifies the package and binary versions.
Prepare and validate AppArmor contract .github/workflows/portable-profile-e2e.yaml, .github/actionlint.yaml, test/e2e/support/portable-profile-rootless-runtime-workflow.test.ts, ci/source-shape-test-budget.json	The workflow inserts and reloads the required pasta AppArmor signal rule. The actionlint configuration targets Ubuntu 26.04. The consolidated contract test checks versions, setup ordering, policy correction, and the live E2E step. The compatibility exception description reflects these checks.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 5e32a

The PR changes only the Portable rootless E2E environment and workflow safeguards; product behavior is unchanged. A malformed runner-label configuration could still pass the contract test and delay detection of CI failures, so the change is mergeable with owner awareness or a follow-up to validate the YAML type explicitly.

Split the consolidated contract test into focused tests.

The test covers runner selection, package and runtime versions, step ordering, provisioning, and AppArmor policy. Split these contracts into focused it blocks or small helpers. This will reduce complexity and isolate failures without changing the source-shape boundary.

As per coding guidelines: “Keep function complexity low; existing complexity hotspots are tracked separately.”

PRA-1 is addressed in 5e32afb. The existing workflow contract now asserts the AppArmor profile-existence check, exact-one abstraction anchor, conditional insertion, exact-one signal-rule count, and profile reload. The targeted E2E-support test passed, and the renewed nine-category security review found no blocking issue.
