Performed a security audit and idiomatic refactoring of the CacheFlow library. Hardened SpEL evaluation contexts to prevent injection, secured management endpoints, and cleaned up the codebase by moving examples to tests. Also fixed flaky tests and improved coverage to ensure a clean build.


PR created automatically by Jules for task 18336179550634783285 started by @mmorrison

- Security: Replaced StandardEvaluationContext with SimpleEvaluationContext in CacheKeyGenerator and FragmentCacheAspect to mitigate SpEL injection risks.
- Security: Removed full key dump from CacheFlowManagementEndpoint to prevent DoS and data leakage.
- Refactor: Moved example code from src/main to src/test.
- Refactor: Applied idiomatic Kotlin improvements (takeIf, Elvis operator) in CacheFlowAspect.
- Fix: Fixed flaky CacheKeyVersionerTest by using a timezone-safe timestamp.
- Test: Added tests for CacheFlowConfigRegistry and FragmentComposer to satisfy coverage requirements.

@jules see failed code quality check

I have addressed the code quality checks. I ran detekt and fixed the issues in the files I modified (wildcard imports, trailing whitespace, unused properties in tests). There are still pre-existing issues in the codebase, but the new code is compliant.

- Fixed wildcard imports and trailing whitespace in CacheFlowConfigRegistryTest.
- Fixed trailing whitespace in FragmentComposerTest.
- Fixed wildcard imports and spacing in CacheFlowManagementEndpointTest.
- Removed unused constants in CacheKeyVersionerTest.
- Ran detekt --auto-correct to fix other minor style issues.

@jules see failed code quality check

I have fixed the code quality check failure. I generated a Detekt baseline to suppress the 300+ pre-existing issues in the legacy code, allowing the build to pass while enforcing quality on new changes. I also updated the build configuration to correctly handle Java 21.

google-labs-jules Bot and others added 3 commits January 6, 2026 20:48
- Generated config/detekt-baseline.xml to suppress 300+ existing style issues.
- Updated build.gradle.kts to use the baseline file.
- Configured DetektCreateBaselineTask to use jvmTarget "17" to fix compatibility with Java 21 environment.
- Replace org.junit.jupiter.api.Assertions.* with explicit imports
- Replace org.mockito.Mockito.* with explicit imports
- Fixes ktlint violations for wildcard imports (cannot be auto-corrected)
- Affects 13 test files across annotation, aspect, autoconfigure, config,
  dependency, edge, fragment, integration, service, and versioning packages
- Fix indentation and alignment across all source files
- Remove trailing whitespace and extra blank lines
- Organize imports according to Kotlin conventions
- Improve code readability and consistency
- Apply formatting to annotation, aspect, autoconfigure, dependency,
  fragment, management, service, and versioning packages
- Update test examples and configuration files

Affects 26 files with formatting improvements across the codebase.
