Build and test Aura with Xcode 27.0 build 27A266a on the xcode-27 runner. Snapshot tests use a test-owned iPhone 17 on iOS 27.0 build 24A434 and wait for it to boot. Missing or mismatched toolchains/runtimes fail visibly. iOS 26 and macOS 26.5 support remain declared.

Re-record and review all 592 iOS reference images for the new rendering environment. Keep the existing four required checks, full device/appearance matrix, comparison tolerances, dependency pins, and failure artifacts. The playback fix has already merged separately.

Minimum-runtime validation adds an iOS 26 CI job that builds, installs, and launches the Xcode 27-built app before running package tests. Two recording-test preconditions now observe native load completion instead of counting task yields; their behavior assertions remain unchanged. Simulator setup has a bounded boot-and-wait operation and retains startup diagnostics on failure.

Validation at 086c3af in CI run 38719577014:

• All five checks passed: both app builds, host package tests, iOS snapshots, and iOS 26 compatibility.
• iOS 26.0 build 23A343: app installation and launch succeeded; all 892 package tests passed, with zero failures or skips. The focused 25-test live-player diagnostic also passed.
• iOS 27: all 79 snapshot tests in 11 suites passed.
• All seven CI-script tests passed.
• Local visual review covered 592 panels and 11 full-resolution comparison pairs; no new missing content or controls were found.

Hosted simulator startup was intermittent in earlier attempts; this candidate completed successfully. Native macOS 26.5 execution remains unverified. Xcode Cloud archive settings and signed distribution remain separate.
