Review: AGP 8.7.2 → 9.2.1 (MAJOR build-system bump) — DeepDiver1975, maintainer review.

This is a one-line bump of the Android Gradle Plugin major version (8.x → 9.x), i.e. the core of the build toolchain. CI is red, which is the decisive signal here:

• Run Android Unit Tests — fail
• Run Android Instrumented Data Tests — fail
• Detekt — fail

(Validation, string-validation and semantic-commit checks pass, but those don't compile the project.)

Root cause / migration risk — Gradle version floor. The repo pins the wrapper to Gradle 8.9 (gradle/wrapper/gradle-wrapper.properties → gradle-8.9-bin.zip). AGP 9.x requires Gradle 9.x; AGP 8.7 was the last line that ran on Gradle 8.9. So this bump cannot build until the wrapper is upgraded to a Gradle 9.x release first. That alone explains the failing build/test jobs.

Other AGP 9 migration concerns to verify before this can go green (not addressable by a version-only bump):

• JDK: CI runs JDK 17 (detekt.yml etc.). AGP 9 requires JDK 17 as the minimum to run Gradle — OK at 17, but worth confirming all jobs are on 17+.
• Removed/changed DSL: AGP 9 removes long-deprecated DSL and the legacy Variant API, and tightens namespace requirements. The build uses Groovy DSL with buildscript{} classpath wiring (build.gradle) plus KSP/ktlint/detekt/sonarqube/cyclonedx plugins applied to all subprojects — each plugin must have an AGP-9-compatible version, and any removed DSL must be migrated.
• AGP–KGP coupling: AGP 9 changes how the Kotlin plugin integrates; the Kotlin Gradle Plugin version (libs.kotlin.gradlePlugin) likely needs a coordinated bump.

Verdict: changes requested. A major build-system jump is not a safe version-only Dependabot bump for this repo. It needs a deliberate migration PR: bump the Gradle wrapper to 9.x, audit the third-party Gradle plugins for AGP-9 compatibility, migrate any removed DSL, and only land once all build/test checks are green. As-is the change does not build.

Recommend: hold (or close in favour of a dedicated AGP-9 migration effort). Not merging from here.
