find-my-files — C# API

Classes
FocusedQueryRewriter	Focused search: a pure query rewrite in the UI layer — the engine is never touched (ADR-0019). Every top-level OR group of the user's query gets the configured noise-path exclusions (!path:"…") and the extension whitelist (one ext:a;b;… term) appended, except where the user already expressed intent: a group mentioning ext:/regex: keeps its own type filter, a group mentioning path: or containing \ keeps its own location.
MainViewModel	Provides a mechanism for releasing unmanaged resources.
NotificationCenter	The InfoBar notification stack: capped at three, Info entries dissolve after five seconds. Every error path in the app funnels through here via Notifier. UI thread only (the Notifier subscription marshals).
PerfPanelViewModel	Supports all classes in the .NET Framework class hierarchy and provides low-level services to derived classes. This is the ultimate base class of all classes in the .NET Framework; it is the root of the type hierarchy.
RequeryOriginExtensions	Helpers over RequeryOrigin.
ResultRow	Supports all classes in the .NET Framework class hierarchy and provides low-level services to derived classes. This is the ultimate base class of all classes in the .NET Framework; it is the root of the type hierarchy.
ResultsPresenter	Supports all classes in the .NET Framework class hierarchy and provides low-level services to derived classes. This is the ultimate base class of all classes in the .NET Framework; it is the root of the type hierarchy.
SearchOrchestrator	When and what to search: 50ms debounce on typing (clearing is instant), a generation counter that discards superseded responses, requery triggers (index changes, stale results) and exception classification. Results are handed to the ResultsPresenter; failures surface through SearchFailed so the ViewModel owns the user-facing wording. All entry points run on the UI thread.
ServiceManagerViewModel	Supports all classes in the .NET Framework class hierarchy and provides low-level services to derived classes. This is the ultimate base class of all classes in the .NET Framework; it is the root of the type hierarchy.
StatusFormatter	All user-facing status wording in one place — keys resolve through Loc (Strings/<lang>/Resources.resw).

Structs
ResultsPublication	Describes one published result set so the view can place the viewport: reset origins scroll to the top, position-preserving origins scroll to RestoreIndex. The seeded index window is where a previously selected row may be re-found.
SearchRequest	Snapshot of what to search — the ViewModel stays the single source of truth for the UI state; the orchestrator only pulls it.

Enums
RequeryOrigin	Why a requery ran. Reset origins land the user at the top of the list; position-preserving origins restore the previous viewport (docs/ARCHITECTURE.md "two requery families").
