Update the update-os-coverage skill to treat image-info.dotnet-dotnet-buildtools-prereqs-docker-main.json as the authoritative source for prereqs tags and to prefer architecture-specific aliases when the Helix queue is processor-specific.

🤖 Copilot Code Review — PR #126524

Holistic Assessment

Motivation: This PR updates WASM/WASI Helix pipeline images from Ubuntu 22.04/24.04 to Ubuntu 26.04, fixes inconsistent .Open queue ID suffixes, standardizes on architecture-specific image tags (-amd64), removes stale CBL-Mariner 2.0 documentation references, and improves the update-os-coverage skill guidance. All of these are well-motivated infrastructure improvements.

Approach: The approach is sound — updating image tags across all three pipeline files (helix-platforms, coreclr helix-queues, libraries helix-queues), fixing pre-existing naming inconsistencies along the way, and codifying lessons learned into the skill documentation. The changes are consistent with existing patterns in the codebase.

Summary: ⚠️ Needs Human Review. The code changes are technically correct — all image tags are verified in image-info, the .Open suffix convention is now consistent with other public queues, and the documentation updates are accurate. However, there are two observations worth human confirmation: (1) helix_browser_wasm_latest/helix_browser_wasm_oldest variables in helix-platforms.yml are defined but never consumed by any pipeline, and (2) the libraries pipeline WASM entries lack public/internal branching unlike other platforms in the same file.

Detailed Findings

✅ Image Tags Verified — All referenced tags exist in `image-info`

Verified against image-info.dotnet-dotnet-buildtools-prereqs-docker-main.json:

ubuntu-26.04-helix-webassembly-amd64 ✅
ubuntu-22.04-helix-webassembly-amd64 ✅
azurelinux-3.0-net11.0-cross-arm64 ✅ (for the cross-building.md docs update)

Both generic (no arch suffix) and processor-specific (-amd64) variants exist in image-info, confirming the switch to -amd64 is valid.

✅ `.Open` Queue ID Fix — Correctly aligns with codebase convention

The PR fixes a pre-existing inconsistency where WASM queue IDs were missing the .Open suffix that all other public container-backed queues use. For example, in helix-platforms.yml:

Before (inconsistent): (Ubuntu.2204.Amd64)AzureLinux.3.Amd64.Open@...
After (consistent): (Ubuntu.2204.Amd64.Open)AzureLinux.3.Amd64.Open@...

This matches the established pattern seen across all other container-backed entries in the file (e.g., (Ubuntu.2204.Amd64.Open), (Debian.13.Amd64.Open), (Fedora.44.Amd64.Open), etc.). The internal variant in coreclr/helix-queues-setup.yml correctly omits .Open in both queue ID and host queue.

✅ Architecture-Specific Tags — Consistent with new guidance

The switch from generic tags (ubuntu-22.04-helix-webassembly) to processor-specific tags (ubuntu-26.04-helix-webassembly-amd64) is correct for Amd64-specific queues and aligns with the new guidance codified in the SKILL.md update.

✅ Documentation Updates — Accurate and well-scoped

linux-build-methodology.md: Correctly removes outdated parenthetical CBL-Mariner 2.0 references. The factual content remains accurate — .NET 8 did use CBL-Mariner 2.0 at release, but the new phrasing ("in the Azure Linux family") avoids naming a specific obsolete version.
cross-building.md: The Docker example image tag azurelinux-3.0-net11.0-cross-arm64 is verified to exist in image-info.
update-os-coverage/SKILL.md: The guidance improvements (exact tag verification, architecture-specific tag preference, validation checklist addition) are well-written and clearly motivated by lessons learned from this PR.

⚠️ Unused Variables — `helix_browser_wasm_*` defined but never consumed

File: eng/pipelines/helix-platforms.yml lines 266-271

The variables helix_browser_wasm_latest and helix_browser_wasm_oldest are updated by this PR, but a search for $(helix_browser_wasm across the entire repo yields zero consumers. By contrast, other Helix platform variables like $(helix_macos_arm64), $(helix_linux_x64_oldest) etc. are actively consumed in pipeline templates.

This is a pre-existing issue — the variables were unused before this PR too. However, it means the "oldest: Ubuntu 22.04" retention in helix-platforms.yml has no actual effect on CI behavior. The real WASM queue definitions in coreclr/helix-queues-setup.yml and libraries/helix-queues-setup.yml all moved to 26.04.

Recommendation: Consider either (a) wiring up the libraries/coreclr WASM entries to use these variables (like other platforms do), or (b) removing the unused variables, or (c) adding a comment noting they're for reference/future use. (Follow-up, not blocking.)

⚠️ Missing Internal Variants — Libraries WASM entries are public-only

File: eng/pipelines/libraries/helix-queues-setup.yml lines 162-172

The WASI, browser_wasm, and browser_wasm_firefox entries define only public queues (with .Open in both queue ID and host queue). This contrasts with:

coreclr/helix-queues-setup.yml which correctly has both public (.Open) and internal (no .Open) branches for browser_wasm
Other platforms in the same libraries file (e.g., Android, Linux arm/arm64) which have public/internal branching

This is a pre-existing issue — the old entries also used .Open in the host queue part (AzureLinux.3.Amd64.Open), so they were already public-only. However, the PR now makes this more visibly public-only by adding .Open to the queue ID as well. If these pipeline paths are ever invoked in internal builds, they would use public queues.

Recommendation: Confirm that the WASM/WASI libraries test jobs are only triggered for public builds. If they could be triggered internally, consider adding internal variants as coreclr/helix-queues-setup.yml does. (Follow-up, not blocking.)

Internal pipeline runs would also incorrectly reference public `.Open` queues, potentially causing test scheduling failures. # Regression No. This updates image versions to stay current with available prereqs images. # Testing Pipeline configuration change only. Validated that the exact container image tag (`ubuntu-26.04-helix-webassembly-amd64`) is present in `image-info.dotnet-dotnet-buildtools-prereqs-docker-main.json`. # Risk Low. This is a Helix queue image version bump with no code changes. The queue identifiers follow the established `.Open` / non-`.Open` convention for public and internal pipelines respectively. # Package authoring no longer needed in .NET 9 IMPORTANT: Starting with .NET 9, you no longer need to edit a NuGet package's csproj to enable building and bump the version. Keep in mind that we still need package authoring in .NET 8 and older versions. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>
