Summary

The first master build of 1.5.0-beta.2 stopped in Android lint (Lint and unit test):

NovaGameDetailActivity.kt:597: Error: Call requires API level 23 (current min is 21): android.content.Context#getSystemService [NewApi]

registerNetworkChangeCallback already returns below Android 7.0 (API 24), and it is the only place networkChangeCallback is set. Cleanup therefore never reached the typed getSystemService call on older devices, but lint cannot see that field invariant. Cleanup now takes and clears the callback exactly as before, then makes the same SDK_INT < N check explicit before asking for ConnectivityManager.

• API 24 and newer: cleanup unregisters the callback that registration added, exactly as before.
• API 21 to 23: registration never sets the callback, so cleanup still returns at the null check and never reaches the new line.
• Unchanged: minSdk stays 21. There is no lint suppression, @TargetApi, baseline or lintFailOnError change.

Steam Frame alpha. This workflow never builds the Frame bundle. The bundle qualified from 5dd0cf58 is attached to the draft release first, and a tag build checks it against pinned digests. That check refuses the tag if any path outside RELEASE_ONLY changed since 5dd0cf58.

• This activity is Android code. The Frame bundle is built from clients/deck with CMake and does not compile it, so RELEASE_ONLY gains exactly this one path.
• The Frame source, tree, bundle digest, size and runtime pins are unchanged.
• NovaReleaseMetadataTest adds three cases:
  • an activity-only change passes;
  • a near-name file (NovaGameDetailActivity.kt.orig) is refused before any release call;
  • another Android source (NovaLibraryActivity.kt) is refused before any release call.

CHANGELOG.md and the 1.5.0 release notes are unchanged.

Preserve this commit when merging; do not squash or rebase. The v1.5.0-beta.2 tag will target the exact candidate above.

Verification

• Frame release controls: the controls embedded in NovaReleaseMetadataTest, run directly with Python, pass all 30 cases on this tree (27 existing, 3 new). Against the previous workflow, the activity-only case is refused, so the new cases detect the change.
• Frame diff: git diff --no-renames --name-only 5dd0cf58 7cc76a20 lists 14 paths, all inside the new RELEASE_ONLY set.
• Not run locally: Android lint, the JVM tests and the APK build. Android lint must pass in this PR. The signed APK is built and checked by the subsequent master and tag pipelines.
