Summary

This PR updates three build tooling dependencies to their latest patch/minor versions:

• Kotlin: 2.2.20 → 2.2.21 (patch release)
• KSP: 2.2.20-2.0.4 → 2.2.21-2.0.4 (Kotlin version alignment)
• Kover: 0.9.2 → 0.9.3 (patch release)

All changes are in gradle/libs.versions.toml:47-52. The PR correctly follows the comment on line 46 requiring Kotlin and KSP versions to stay in sync.

Suggested Improvements

ℹ️ Consider verification approach for tooling updates

While CI checks have passed successfully, future tooling updates could benefit from additional verification:

1. Build validation across all modules: Ensure all 9 modules compile successfully
2. Coverage report generation: Verify Kover still produces valid coverage reports (./gradlew koverXmlReportMergedCoverage)
3. KSP code generation: Confirm Hilt/Room/other annotation processors work correctly
4. Detekt integration: Validate no new Kotlin language feature conflicts

These checks are particularly important for:

• Kotlin compiler updates (can affect language features/warnings)
• KSP updates (can affect code generation patterns)
• Kover updates (can affect coverage calculation/reporting)

---

Good Practices Observed

• ✅ Maintained Kotlin/KSP version compatibility per inline comment
• ✅ Updated all three tools together (prevents version skew)
• ✅ CI checks passed (Lint, Test, Security Scan, Coverage)
• ✅ Minimal, focused change scope

---

Compatibility Analysis

Kotlin 2.2.20 → 2.2.21: Patch release, typically only bug fixes and stability improvements. No breaking changes expected.

KSP 2.2.20-2.0.4 → 2.2.21-2.0.4: Version bump to align with Kotlin 2.2.21. KSP API version (2.0.4) remains unchanged, indicating processor compatibility is maintained.

Kover 0.9.2 → 0.9.3: Minor version bump. The existing Kover configuration in build.gradle.kts:49-117 uses standard APIs that should remain stable across 0.9.x releases.

Dependencies verified:

• ✅ Kotlin plugins properly versioned (lines 147-150 in gradle/libs.versions.toml)
• ✅ KSP plugin properly versioned (line 152)
• ✅ Kover plugin properly versioned (line 151)
• ✅ No direct Kotlin runtime version conflicts

---

Verdict

Recommendation: ✅ Approve and merge

This is a low-risk maintenance update following proper version compatibility practices. All CI checks have passed, and the changes follow the project's established pattern for synchronized Kotlin/KSP updates.
