Complexity hotspots

Large and churn-heavy files are good places to look when planning refactors or targeted tests.

Recent churn

Path	Why it matters
src-tauri/src/commands/ai/streaming_exec.rs	Process execution, streaming, cancellation, and watchdog behavior changed often recently.
frontend/src/app/useAppController.test.ts	Central workflow tests changed often as app state behavior evolved.
crates/qa-scribe-core/src/generation/html.rs	Backend HTML handling is sensitive because it touches generated rich content.
.github/workflows/release.yml	Release automation has many packaging paths and platform cases.

Large source files

Path	Notes
scripts/build_apt_repository.py	Largest script by line count.
scripts/validate_linux_package_metadata.py	Package metadata validation logic.
.github/workflows/release.yml	Largest CI workflow.

Before changing these areas, read Testing and run a focused check followed by bun run verify:fast or bun run verify depending on scope.
