Recent churn is highest in frontend results/export work, the comparison engine, API handlers, and transport workflows. Lockfiles and generated Tauri schemas produce large churn numbers, so they should not be read as product complexity by themselves.

Product hotspot	Approximate churn driver
frontend/src/features/results/htmlExport.ts	HTML export model and rendering changes.
src/comparison/engine.rs	Core comparison planning, flexible keys, result generation.
tests/comparison_engine_integration.rs	Regression coverage for comparison behavior.
src/api/handlers.rs	HTTP workflow handlers and error/attachment behavior.
frontend/src/components/ResultsTable.tsx	Results table search, sort, expansion, and chunk rendering.
frontend/src/hooks/useComparisonWorkflow.ts	UI workflow orchestration and stale async guards.

Bot-attributed commits

The history scan found 288 commits. Of those, 63 commits, about 21.9%, contain bot-style attribution such as a [bot] account in the author or commit body. Another 79 commits, about 27.4%, contain obvious AI co-authorship traces such as Co-Authored-By: Claude Fable 5. Treat both numbers as lower bounds, since editor-side AI tools generally leave no trace in git metadata.

Complexity

Largest source file	Lines	Why it matters
tests/comparison_engine_integration.rs	2,331	Broad comparison regression coverage.
tests/linux_package_metadata_integration.rs	1,294	Linux package metadata gates.
frontend/src/features/results/resultsSurface.css	1,258	Results surface styling.
tests/backend_workflow_integration.rs	1,123	Shared backend workflow coverage.
tests/response_contracts.rs	1,004	API and response contract coverage.
src/comparison/engine.rs	836	Core comparison algorithm and planning.

The largest implementation hotspots are documented in cleanup opportunities. Dependency counts and major libraries are listed in dependencies.
