🔍 CI Failure Analysis — PR #35602

Verdict: All failures are pre-existing on net11.0. They are not caused by this PR.

This PR is a Maestro codeflow update that bumps a single Android-x64 MIBC AOT profile package version. That change physically cannot affect iOS trimmer behavior, macOS build target resolution, or Windows tests.

Pipeline summary

Pipeline	Build	Failures	Verdict
maui-pr	1437470	5 jobs (4 integration tests + 1 macOS build)	Pre-existing on net11.0
maui-pr-devicetests	1437469	6 jobs	Pre-existing on net11.0
maui-pr-uitests	1437468	90 jobs	Pre-existing on net11.0

Root cause #1 — iOS Release / TrimFull integration tests (NETSDK1144)

13× ILLink IL2026 trim-analysis errors on Microsoft.Maui.Handlers.HybridWebViewHandler.SchemeHandler and WebViewScriptMessageHandler (both marked RequiresUnreferencedCode for System.Text.Json dynamic serialization). These warnings are promoted to hard errors by -p:TreatWarningsAsErrors=true -p:TrimMode=full in the integration test build args.

Affected jobs (identical on the PR build and on every recent net11.0 main build):

• Integration Tests - AOT (macOS)
• Integration Tests - RunOniOS_MauiRelease (ARM64)
• Integration Tests - RunOniOS_MauiReleaseTrimFull (ARM64)
• Integration Tests - RunOniOS_MauiReleaseTrimFull_CoreCLR (ARM64)

Root cause #2 — Build macOS (Release) (MSB4019)

error MSB4019: The imported project ".buildtasks/Microsoft.Maui.Core.After.targets" was not found.

Originates from Essentials.AI.Sample.csproj via $(AfterMicrosoftNETSdkTargets). Looks like a transient build-task-ordering glitch — not deterministic in baselines, and definitely not caused by an Android-x64 MIBC package bump.

Evidence this is pre-existing

I cross-referenced the 5 most recent net11.0 main builds (last successful baseline: 1431279 on 2026-05-22) — they all show the same 4 integration test failures as this PR. The net11.0 branch has been red across all three MAUI pipelines (maui-pr, maui-pr-devicetests, maui-pr-uitests) for at least 2 weeks.

Recommended next steps

1. Fix the underlying HybridWebViewHandler IL2026 trim errors on net11.0 — that's the real blocker for the whole branch.
2. Once net11.0 is green, retrigger this PR with /azp run maui-pr, maui-pr-uitests, maui-pr-devicetests — the Maestro change itself is benign and should pass.

NEEDS_DISCUSSION (confidence: high) — multi-model review (4/4), no code-level findings.

Clean automated Maestro codeflow bump of optimization.android-x64.MIBC.Runtime (Android AOT PGO profile data); the version is consistent across eng/Versions.props and eng/Version.Details.xml. Mechanically correct.

The only reason this isn't a clean LGTM: CI is red (multiple maui-pr legs incl. UI/Device tests). For a profile-data bump these failures are most likely infra/unrelated, but please confirm a green run before merge.
